There is still a lack of reliable clinical tools to predict the incidence of HDP. The purpose of this study was to establish and validate a nomogram prediction model for assessing the risk of HDP in pregnant women based on laboratory indicators and HDP risk factors. Method: A total of 307 pregnant women who were hospitalized in the obstetrics and gynecology department of our hospital were included in this study, and were randomly divided into a training cohort and validation cohort at a ratio of 7:3. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for the development of HDP on laboratory indicators as well as risk factors for HDP in the training cohort of patients. The results of the multivariate regression model were visualized by forest plots. A nomogram was constructed based on the results of multivariate logistic regression to predict the risk of HDP in pregnant women. The validity of the risk prediction model was evaluated by the area under the receiver operating characteristic curve (AUC), the consistency index (C-index), the calibration curve and the decision curve analysis (DCA). Results: BMI ≥ 25 Kg/m2, total cholesterol in early pregnancy, uric acid and proteinuria in late pregnancy were independent risk factors for HDP. The AUC and C-index of the nomogram constructed by the above four factors were both 0.848. The calibration curve is closely fitted with the ideal diagonal, showing a good consistency between the nomogram prediction and the actual observation of HDP. The DCA has demonstrated the great clinical utility of nomogram. Internal verification proves the reliability of the predicted nomograms. Conclusion: The BTUP nomogram model based on laboratory indicators and risk factors proposed in this study showed good predictive value for the risk assessment of HDP. It is expected to provide evidence for clinical prediction of the risk of HDP in pregnant women.展开更多

Globally, the incidence of HDP increased from 16.30 million to 18.08 million, with a total increase of about 10.9% from 1990 to 2019. Umbilical Doppler study in hypertensive disorders of pregnancy helps to predict neonatal outcomes and prevent neonatal and maternal morbidity and mortality. Objective: This study aims to determine the incidence of abnormal umbilical Doppler among hypertensive pregnant women, to identify the adverse neonatal outcomes associated with abnormal umbilical Doppler, and also to detect the diagnostic predictive values of umbilical Doppler to neonatal outcomes at KCMC. Material and methods: A hospital-based prospective cohort study included women with hypertensive disorders of pregnancy from the gestational age of 28 weeks and above, followed up to delivery during the study period from August 2022 to March 2023. Multivariate logistic regression analysis was used to determine the association between AUD and neonatal outcomes. Results: Out of 112 women with HDP, the incidence of abnormal umbilical Doppler was 38 (33.93%). Abnormal umbilical Doppler was associated with neonates with low birth weight aOR (95% of CI) of 4.52 (1.59 - 12.83) p = 0.005 and neonatal ICU admission 9.71 (2.90 - 32.43) p Conclusion: The incidence of abnormal umbilical Doppler is high in hypertensive disorders of pregnancy which is associated with an increase in neonatal low birth weight and neonatal ICU admissions, the sensitivity of abnormal umbilical Doppler in prediction of low birth weight and neonatal ICU admission is significant hence the routine use of umbilical Doppler assessment among hypertensive pregnant women is crucial.展开更多

Leveraging data from the Jiangsu Birth Cohort, in the present study, we re-visited such associations in one-year-old infants from 2 576 singleton pregnancies and 261 twin pregnancies. We first assessed infant neurodevelopment by the Bayley Scales of Infant and Toddler Development Screening Test (the Third Edition), and then estimated its association with maternal HDP using general linear regression models and Poisson regression models. In singleton pregnancies, compared with mothers unexposed to HDP, infants born to mothers with chronic hypertension exhibited a lower score (β, −0.67;95% confidence interval [CI], −1.19-−0.15) and a higher risk of "non-optimal" gross motor development (risk ratio [RR], 2.21;95% CI, 1.02-4.79);in twin pregnancies, infants born to mothers with HDP exhibited lower scores in cognition (β, −0.49;95% CI, −0.96-−0.01), receptive communication (β, −0.55;95% CI, −1.03-−0.06), and gross motor (β, −0.44;95% CI, −0.86-−0.03), and at a higher risk of "non-optimal" gross motor development (RR, 2.12;95% CI, 1.16-3.88). These findings indicate that infants born to mothers with HDP may have inferior neurodevelopment outcomes at the age of one year.展开更多

The aim is to determine the socio-demographic characteristics and maternal prognosis of these women with Hypertension during pregnancy. Material and Method: We conducted a cross-sectional study, we interview patients and after discussion we transcripts in a database in Excel software before analysis with SPSS version 20.0 and Stata 14.0 The qualitative variables have been summarised by the Percentage and the quantitative variables will be summarised by Means and Standard Deviation. The associations of the variables were calculated by Pearson’s chi-square test with a significance level set at a p-value Result: The average age of the patients was 30.33 ± 7.020 years, 92.1% were married, 79.8% lived in urban areas, most of the patients were overweight (43%), 92.1% of them had monofetal pregnancies, 36% were multiparous, 34.2% had a previous history of preeclampsia in pregnancy and 14% were known to have hypertension. Pre-eclampsia was the most frequent form of hypertension in pregnancy with 73.68% of cases and represents 84.8% of severe forms of hypertension in pregnancy, 53.4% of the patients delivered vaginally. Eclampsia was the most frequent complication in our patients with 31.7% frequency and among the socio-demographic parameters, age and body mass index were significantly associated with maternal complications. Conclusion: Maternal age and body mass index are important socio-demographic factors associated with the occurrence of maternal complications in women with hypertensive disorders in pregnancy.展开更多

Considering the large population with wide geographic area of China, we aimed to add more in- formation regarding the risk factors for hypertensive disorders of pregnancy. A case-control study was performed on 373 hypertensive cases and 507 normotensive controls. Participants were recruited from 2008 to 2014 in Yichang Maternal and Child Health Care Center in Hubei province and Anyang Mater- nal and Child Health Care Hospital in Henan province, China. Socio-demographic factors, fam- ily-related factors, pregnancy-associated factors, factors related to daily life behaviors and psychosocial factors were investigated with respect to hypertensive disorders in pregnancy through well-designed questionnaire. Chi-square test, t-test, univariate logistic regression analysis, and multivariate logistic re- gression analysis were used to find the possible risk factors behind hypertensive disorders in pregnancy. The results showed that family history of cardiovascular diseases （OR=6.18, 95% CI, 2.37 to 16.14）, history of pregnancy-induced hypertension （OR=16.64, 95% CI, 5.74 to 48.22）, low maternal educa- tional level （OR=2.81, 95% CI, 1.30 to 6.04）, and poor relationship with their parents-in-law （OR=3.44, 95% CI, 1.55 to 7.59） had statistically significant associations with hypertensive disorders in pregnancy through multivariate logistic regression analysis. Increased maternal age, increased pre-pregnancy body mass index, living in rural area, low paternal education level, family history of hypertension, passive smoking one year before and/or in pregnancy, and poor sleeping quality were significantly associated with hypertensive disorders in pregnancy from univariate logistic regression analysis while the associa- tions became uncertain when they were entered for multivariate logistic regression analysis. It was con- cluded that family history of cardiovascular diseases, history of pregnancy-induced hypertension, low maternal educational level, and poor relationship with their parents-in-law were independent risk factors for hypertensive disorders among Chinese pregnant women.展开更多

The objective of this study was to describe the prognosis in the postpartum period of patients with HDP in Departmental University Hospital of Borgou CHUD-B from Parakou in 2020. <b><i>Methods</i>: </b>The study was prospective with a descriptive and analytical design and was conducted from January 2020 to September 2020. Patients with HDP were recruited from the gynecology-obstetrics department and each followed for 3 months in the cardiology department. HDP was classified according to the International Society for the Study of Hypertension in Pregnancy, and blood pressure (BP) was taken according to WHO recommendations. Self-measurement of BP at home was performed to assess blood pressure control outside the hospital. Epidata 3.1 and SPSS 21 software were used for data processing and analysis. P values < 5% were considered statistically significant. <b><i>Results</i>: </b>During the study period, the hospital frequency of HDP was 15.6%. The frequency of maternal complications in the postpartum period was 28% (severe hypertension: 23.2%;eclampsia: 3.6%;puerperal psychosis: 1.2%). At the end of the three-month follow-up, blood pressure returned to normal in 73.2% of cases;it persisted in 26.8% of women. Factors associated with persistence of hypertension after multivariate analysis were, overweight/obesity RRa 8.664 [1.566 - 47.941], (p = 0.013);family history of hypertension RRa 6.499 [1.493 - 28.289], (p = 0.013);history of hypertension in previous pregnancies RRa 7.764 [1.561 - 38.601], (p < 0.012). <b><i>Conclusion</i>: </b>The frequency of HDP is not negligible at CHUD-B/A. The evolution of these HDP was marked in more than a quarter of cases by complications in the postpartum period followed by a persistence of hypertension 3 months after childbirth predicted by cardiovascular risk factors.</span></span>展开更多

The aim of this study was to investigate whether the goal-directed fluid therapy （GDFT） with LiDCOrapid system can improve well-being of both HDP parturient and their babies. Methods： Fifty-two stable HDP parturient scheduled for elective cesarean delivery were recruited. After loading with 10 ml/kg lactated Ringer＇s solution （LR）, parturient were randomized to the GDFT and control group. In the GDFT group, individualized fluid therapy was guided by increase in stroke volume （ASV） provided via LiDCO rapid system. The control group received the routine fluid therapy. The primary endpoints included maternal hypotension and the doses of vasopressors administered prior to fetal delivery. The secondary endpoints included umbilical blood gas abnormalities and neonatal adverse events. Results： The severity of HDP was similar between two groups. The total LR infusion （P 〈 0.01） and urine output （P 〈 0.05） were higher in the GDFT group than in the control group. Following twice fluid challenge tests, the systolic blood pressure, mean blood pressure, cardiac output and SV in the GDFT group were significantly higher, and the heart rate was lower than in the control group. The incidence of maternal hypotension and doses of phenylephrine used prior to fetal delivery were significantly higher in the control group than in the GDFT group （P 〈 0.01）. There were no differences in the Apgar scores between two groups. In the control group, the mean values of pH in umbilical artery/vein were remarkably decreased （P 〈 0.05）, and the incidences of neonatal hypercapnia and hypoxemia were statistically increased （P 〈 0.05） than in the GDFT group. Conclusions： Dynamic responsiveness guided fluid therapy with the LiDCOrapid system may provide potential benefits to stable HDP parturient and their babies.展开更多

We analyzed the high-risk factors inducing hypertensive disorders in pregnancy （HDP） and estimated the potential effect of anti-oxidants administration, including vitamin C （VC）, vitamin E （VE） and Salvia Miltiorrhiza L （SML）, a Chinese herb medicine, in amelioration of the high-risk factors in pregnancy. Methods From April 2005 to July 2006, 4814 pregnant women from 24 national wide cooperative hospitals were involved in this prospective research. The participants were randomly divided into two groups： 1607 cases were in anti-oxidants group with administration of vitamins and SML; 3207 cases were in control group without any medicine given. Every participant was under monitoring for the morbidity of HDP and the high-risk factors were investigated in HDP cases in each group. Results （1）The morbidity of HDP was 3.55% in anti-oxidants group vs. 4.18% in control group. No statistical difference existed between the two groups （P〉0.05）. （2） In anti-oxidants group, the HDP morbidities among three subgroups： VC ＋ VE ＋ SML, VC ＋ VE and SML only, were 5.51%, 3.05% and 5% respectively. It showed no statistical difference among three remedies （P 〉0.05）. （3） The related index of factors affecting HDP showed in intensity sequence as follows： family HDP history 〉 profession 〉 education level 〉 age 〉 body weight. The incidence of HDP in normal population was 3.51%, and the incidence of HDP in high-risk pregnant women （family HDP history, heavy physical labor, low education level （middle school and below）, age 〉40, body mass index 〉24） was 5.84%, which was obviously higher than that in normal population （P 〈0.01）. In anti-oxidants group, the probability of HDP in women with high-risk factors was 3.81%, which was obviously lower than that in control group with high-risk factors at 7.14% （P〈0.01）. （4） In control group, the morbidity of HDP in women with family HDP history （especially with sisters＇）, heavy physical labor, middle school and below, age 〉35 was： 50.00%, 15.22%, 6.33%, 26.28% and 5.75%, respectively, and that in anti-oxidants group was 0, 7.69%, 3.74%, 9.27% and 2.67%, respectively, which was obviously lower than that in control group. Conclusions The high-risk factors prone to induce HDP included： family history of HDP, heavy physical labor, low education level, aging and obesity. No impressive effect of anti-oxidants application was found in preventing HDP in general population but the remedy demonstrated positive effect on preventing HDP in pregnant women with high-risk factors.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

The frequencies of genotype and allele were compared between the two groups. The results showed that with-308G→A polymorphism distribution, the allele frequency of TNF2 and the frequency of the genotype TNF2/1 in the patient group was significantly higher in the patient group than in control group （P〈0.05）. A significant difference in genotype distribution of --850C→T polymorphism was observed between the two groups. The allele frequencies of T in patient group was higher in the control group as compared with the patient group. The frequencies of CT and TT genotypes were lower in the patient group. It is concluded that the TNF2 allele of -308 is associated with the occurrence of hypertensive disorder complicating pregnancy, while T allele of--850 may be the protective factor against the development of the disease. TNF2/1 CC may be susceptibility genotype of hypertensive disorder complicating pregnancy.展开更多

Compared with the healthy pregnant group, the expression of endogenous ouabain dramatically increased in the HDCP groups （P〈0.01）. There was a significantly positive correlation between the expression of en- dogenous ouabain with ET-1 （r= 0.5567, P〈0.01）, while the correlation of endogenous ouabain and NO was significantly negative （r=-0.6895, P〈0.01）. As expected, the correlation between ET-1 and NO was negative （r=-0.7796, P〈0.01）. ET-1 concentrations of maternal and cord sera in HDCP groups were significantly higher in comparison with healthy pregnant group （P〈0.01）. On the contrast, NO concentrations were much lower in the maternal and cord sera of HDCP groups as compared with healthy pregnant group （P〈0.01）. Our data suggest that endogenous ouabain is directly involved in the nosogenesis of HDCP, with accompanying decreased NO and the elevated of ET-1.展开更多

Methods： Radioimmunoassay was used to test the level of serum Leptin, and the activity of EMCA was determined chemically in 38 pregnant women with hypertensive disorder complicating pregnancy and 36 normotensive pregnant women. Results： The level of serum Leptin in hypertensive disorder complicating pregnancy（gestational hypertension： 13.76 ± 3.46 ng/ml; preeclampsia： 15.76 ± 5.47 ng/ml; eclampsia： 18.32 ± 6.38 ng/ml）was significantly higher than that in normotensive pregnant women （11.33 ± 2.93 ng/ml） ,respectively. The average EMCA activity of patients with hypertensive disorder complicating pregnancy （gestational hypertension： 1.65 ± 0.24 μmol·pi/mg.h ; preeclampsia： 1.37 ± 0.19 μ mol·pi/mg·h;eclampsia：1.12 ± 0.14 μmol·pi/mg·h） was significantly lower than that of normotensive pregnant women（1.83 ± 0.38 μ mol·pi/mg·h）,respectively. There was a negative correlation between the level of serum Leptin and the activity of RMCA in hypertensive disorder complicating pregnancy （r = -0.63）. Conclusion： Inhibition of EMCA activity of erythrocyte in hypertensive disorder complicating pregnancy may increase cytoplasmic free calcium, which contributes to the development of hypertensive disorder complicating pregnancy. The negative correlation between the level of serum Leptin and the activity of EMCA, also suggested that serum Leptin and the activity of EMCA may play a role in the development of hypertensive disorder complicating pregnancy.展开更多

文摘Background: Hypertensive disorder of pregnancy (HDP) is a group of diseases in which pregnancy and elevated blood pressure coexist. There is still a lack of reliable clinical tools to predict the incidence of HDP. The purpose of this study was to establish and validate a nomogram prediction model for assessing the risk of HDP in pregnant women based on laboratory indicators and HDP risk factors. Method: A total of 307 pregnant women who were hospitalized in the obstetrics and gynecology department of our hospital were included in this study, and were randomly divided into a training cohort and validation cohort at a ratio of 7:3. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for the development of HDP on laboratory indicators as well as risk factors for HDP in the training cohort of patients. The results of the multivariate regression model were visualized by forest plots. A nomogram was constructed based on the results of multivariate logistic regression to predict the risk of HDP in pregnant women. The validity of the risk prediction model was evaluated by the area under the receiver operating characteristic curve (AUC), the consistency index (C-index), the calibration curve and the decision curve analysis (DCA). Results: BMI ≥ 25 Kg/m2, total cholesterol in early pregnancy, uric acid and proteinuria in late pregnancy were independent risk factors for HDP. The AUC and C-index of the nomogram constructed by the above four factors were both 0.848. The calibration curve is closely fitted with the ideal diagonal, showing a good consistency between the nomogram prediction and the actual observation of HDP. The DCA has demonstrated the great clinical utility of nomogram. Internal verification proves the reliability of the predicted nomograms. Conclusion: The BTUP nomogram model based on laboratory indicators and risk factors proposed in this study showed good predictive value for the risk assessment of HDP. It is expected to provide evidence for clinical prediction of the risk of HDP in pregnant women.
文摘Hypertensive disorders of pregnancy (HDP) are the most common maternal and perinatal health challenges. Globally, the incidence of HDP increased from 16.30 million to 18.08 million, with a total increase of about 10.9% from 1990 to 2019. Umbilical Doppler study in hypertensive disorders of pregnancy helps to predict neonatal outcomes and prevent neonatal and maternal morbidity and mortality. Objective: This study aims to determine the incidence of abnormal umbilical Doppler among hypertensive pregnant women, to identify the adverse neonatal outcomes associated with abnormal umbilical Doppler, and also to detect the diagnostic predictive values of umbilical Doppler to neonatal outcomes at KCMC. Material and methods: A hospital-based prospective cohort study included women with hypertensive disorders of pregnancy from the gestational age of 28 weeks and above, followed up to delivery during the study period from August 2022 to March 2023. Multivariate logistic regression analysis was used to determine the association between AUD and neonatal outcomes. Results: Out of 112 women with HDP, the incidence of abnormal umbilical Doppler was 38 (33.93%). Abnormal umbilical Doppler was associated with neonates with low birth weight aOR (95% of CI) of 4.52 (1.59 - 12.83) p = 0.005 and neonatal ICU admission 9.71 (2.90 - 32.43) p Conclusion: The incidence of abnormal umbilical Doppler is high in hypertensive disorders of pregnancy which is associated with an increase in neonatal low birth weight and neonatal ICU admissions, the sensitivity of abnormal umbilical Doppler in prediction of low birth weight and neonatal ICU admission is significant hence the routine use of umbilical Doppler assessment among hypertensive pregnant women is crucial.

文摘Inconsistent findings have been reported regarding the associations between hypertensive disorders in pregnancy (HDP) and infant neurodevelopment. Leveraging data from the Jiangsu Birth Cohort, in the present study, we re-visited such associations in one-year-old infants from 2 576 singleton pregnancies and 261 twin pregnancies. We first assessed infant neurodevelopment by the Bayley Scales of Infant and Toddler Development Screening Test (the Third Edition), and then estimated its association with maternal HDP using general linear regression models and Poisson regression models. In singleton pregnancies, compared with mothers unexposed to HDP, infants born to mothers with chronic hypertension exhibited a lower score (β, −0.67;95% confidence interval [CI], −1.19-−0.15) and a higher risk of "non-optimal" gross motor development (risk ratio [RR], 2.21;95% CI, 1.02-4.79);in twin pregnancies, infants born to mothers with HDP exhibited lower scores in cognition (β, −0.49;95% CI, −0.96-−0.01), receptive communication (β, −0.55;95% CI, −1.03-−0.06), and gross motor (β, −0.44;95% CI, −0.86-−0.03), and at a higher risk of "non-optimal" gross motor development (RR, 2.12;95% CI, 1.16-3.88). These findings indicate that infants born to mothers with HDP may have inferior neurodevelopment outcomes at the age of one year.
文摘Background: Hypertensive disease in pregnancy is an important cause of morbidity, long-term disability, and maternal and neonatal mortality. The aim is to determine the socio-demographic characteristics and maternal prognosis of these women with Hypertension during pregnancy. Material and Method: We conducted a cross-sectional study, we interview patients and after discussion we transcripts in a database in Excel software before analysis with SPSS version 20.0 and Stata 14.0 The qualitative variables have been summarised by the Percentage and the quantitative variables will be summarised by Means and Standard Deviation. The associations of the variables were calculated by Pearson’s chi-square test with a significance level set at a p-value Result: The average age of the patients was 30.33 ± 7.020 years, 92.1% were married, 79.8% lived in urban areas, most of the patients were overweight (43%), 92.1% of them had monofetal pregnancies, 36% were multiparous, 34.2% had a previous history of preeclampsia in pregnancy and 14% were known to have hypertension. Pre-eclampsia was the most frequent form of hypertension in pregnancy with 73.68% of cases and represents 84.8% of severe forms of hypertension in pregnancy, 53.4% of the patients delivered vaginally. Eclampsia was the most frequent complication in our patients with 31.7% frequency and among the socio-demographic parameters, age and body mass index were significantly associated with maternal complications. Conclusion: Maternal age and body mass index are important socio-demographic factors associated with the occurrence of maternal complications in women with hypertensive disorders in pregnancy.

文摘Summary： The prevalence of hypertensive disorders in China was much higher than that in the United States. Considering the large population with wide geographic area of China, we aimed to add more in- formation regarding the risk factors for hypertensive disorders of pregnancy. A case-control study was performed on 373 hypertensive cases and 507 normotensive controls. Participants were recruited from 2008 to 2014 in Yichang Maternal and Child Health Care Center in Hubei province and Anyang Mater- nal and Child Health Care Hospital in Henan province, China. Socio-demographic factors, fam- ily-related factors, pregnancy-associated factors, factors related to daily life behaviors and psychosocial factors were investigated with respect to hypertensive disorders in pregnancy through well-designed questionnaire. Chi-square test, t-test, univariate logistic regression analysis, and multivariate logistic re- gression analysis were used to find the possible risk factors behind hypertensive disorders in pregnancy. The results showed that family history of cardiovascular diseases （OR=6.18, 95% CI, 2.37 to 16.14）, history of pregnancy-induced hypertension （OR=16.64, 95% CI, 5.74 to 48.22）, low maternal educa- tional level （OR=2.81, 95% CI, 1.30 to 6.04）, and poor relationship with their parents-in-law （OR=3.44, 95% CI, 1.55 to 7.59） had statistically significant associations with hypertensive disorders in pregnancy through multivariate logistic regression analysis. Increased maternal age, increased pre-pregnancy body mass index, living in rural area, low paternal education level, family history of hypertension, passive smoking one year before and/or in pregnancy, and poor sleeping quality were significantly associated with hypertensive disorders in pregnancy from univariate logistic regression analysis while the associa- tions became uncertain when they were entered for multivariate logistic regression analysis. It was con- cluded that family history of cardiovascular diseases, history of pregnancy-induced hypertension, low maternal educational level, and poor relationship with their parents-in-law were independent risk factors for hypertensive disorders among Chinese pregnant women.

文摘Background:Hypertensive disorders of pregnancy(HDP)are among obstetrics'most intriguing and yet unsolved problems.It is one of the major causes of maternal and perinatal morbidity and mortality.This study estimates the prevalence of hypertensive disorders of pregnancy,their associated risk factors and pregnancy complications in primiparous women.Methods:All primigravida who gave birth in our hospital from December 2020 to December 2021 were included in the study.The prevalence,risk factors,mode of delivery,and maternal and fetal outcomes of hypertensive disorders of pregnancy in primigravidae were collected from the patient's medical records.Statistical analysis was done using the SPSS 18.0 software package.The Chi-square test was used to analyse the association between the risk factors and hypertensive disorders of pregnancy in primigravida.Results:A total of 807 women were included in the study,and the mean age was 26.34±3.84 years.The prevalence of hypertensive disorders of pregnancy in primigravidae was found to be 18.6%.Among the prevalent population,79.3%of women had gestational hypertension.The findings indicate that hypertension in pregnancy has a significant relationship with risk factors such as increased maternal age(p<0.004),family history of hypertension in pregnancy(p<0.001),body mass index>30 kg/m^(2)(p<0.001),hyperglycaemia in pregnancy(p<0.001),IVF pregnancy(p<0.004)and polycystic ovary syndrome(p<0.001).The most reported adverse maternal and perinatal outcomes were placental abruption(p<0.001),postpartum haemorrhage(p<0.001),prematurity(p<0.001),and fetal growth restriction(p<0.001).Conclusion:The study emphasises the importance of knowledge and timely assessment of risk factors of HDP.It also highlights the need for pre-conceptional counselling,which includes early detection,careful monitoring and treatment of HDP for preventing morbidity and mortality related to this disorder and it should be followed up even in the postpartum period.
文摘Background： Hypotension induced by combined spinal epidural anesthesia in parturient with hypertensive disorders of pregnancy （HDP） can easily compromise blood supply to vital organs including uteroplacental perfusion and result in fetal distress. The aim of this study was to investigate whether the goal-directed fluid therapy （GDFT） with LiDCOrapid system can improve well-being of both HDP parturient and their babies. Methods： Fifty-two stable HDP parturient scheduled for elective cesarean delivery were recruited. After loading with 10 ml/kg lactated Ringer＇s solution （LR）, parturient were randomized to the GDFT and control group. In the GDFT group, individualized fluid therapy was guided by increase in stroke volume （ASV） provided via LiDCO rapid system. The control group received the routine fluid therapy. The primary endpoints included maternal hypotension and the doses of vasopressors administered prior to fetal delivery. The secondary endpoints included umbilical blood gas abnormalities and neonatal adverse events. Results： The severity of HDP was similar between two groups. The total LR infusion （P 〈 0.01） and urine output （P 〈 0.05） were higher in the GDFT group than in the control group. Following twice fluid challenge tests, the systolic blood pressure, mean blood pressure, cardiac output and SV in the GDFT group were significantly higher, and the heart rate was lower than in the control group. The incidence of maternal hypotension and doses of phenylephrine used prior to fetal delivery were significantly higher in the control group than in the GDFT group （P 〈 0.01）. There were no differences in the Apgar scores between two groups. In the control group, the mean values of pH in umbilical artery/vein were remarkably decreased （P 〈 0.05）, and the incidences of neonatal hypercapnia and hypoxemia were statistically increased （P 〈 0.05） than in the GDFT group. Conclusions： Dynamic responsiveness guided fluid therapy with the LiDCOrapid system may provide potential benefits to stable HDP parturient and their babies.
文摘Background This is a prospective clinical study based on a large sample gathered from multiple centers in China, subordinating to 10th Five-Year Plan of National Science ＆ Technology Progression. We analyzed the high-risk factors inducing hypertensive disorders in pregnancy （HDP） and estimated the potential effect of anti-oxidants administration, including vitamin C （VC）, vitamin E （VE） and Salvia Miltiorrhiza L （SML）, a Chinese herb medicine, in amelioration of the high-risk factors in pregnancy. Methods From April 2005 to July 2006, 4814 pregnant women from 24 national wide cooperative hospitals were involved in this prospective research. The participants were randomly divided into two groups： 1607 cases were in anti-oxidants group with administration of vitamins and SML; 3207 cases were in control group without any medicine given. Every participant was under monitoring for the morbidity of HDP and the high-risk factors were investigated in HDP cases in each group. Results （1）The morbidity of HDP was 3.55% in anti-oxidants group vs. 4.18% in control group. No statistical difference existed between the two groups （P〉0.05）. （2） In anti-oxidants group, the HDP morbidities among three subgroups： VC ＋ VE ＋ SML, VC ＋ VE and SML only, were 5.51%, 3.05% and 5% respectively. It showed no statistical difference among three remedies （P 〉0.05）. （3） The related index of factors affecting HDP showed in intensity sequence as follows： family HDP history 〉 profession 〉 education level 〉 age 〉 body weight. The incidence of HDP in normal population was 3.51%, and the incidence of HDP in high-risk pregnant women （family HDP history, heavy physical labor, low education level （middle school and below）, age 〉40, body mass index 〉24） was 5.84%, which was obviously higher than that in normal population （P 〈0.01）. In anti-oxidants group, the probability of HDP in women with high-risk factors was 3.81%, which was obviously lower than that in control group with high-risk factors at 7.14% （P〈0.01）. （4） In control group, the morbidity of HDP in women with family HDP history （especially with sisters＇）, heavy physical labor, middle school and below, age 〉35 was： 50.00%, 15.22%, 6.33%, 26.28% and 5.75%, respectively, and that in anti-oxidants group was 0, 7.69%, 3.74%, 9.27% and 2.67%, respectively, which was obviously lower than that in control group. Conclusions The high-risk factors prone to induce HDP included： family history of HDP, heavy physical labor, low education level, aging and obesity. No impressive effect of anti-oxidants application was found in preventing HDP in general population but the remedy demonstrated positive effect on preventing HDP in pregnant women with high-risk factors.
文摘The growing incidence of obesity and the rising trend of increased age during pregnancy have led to a high number of pregnant women with chronic kidney disease(CKD).Chronic hypertension is commonly associated with CKD and is not only the result of renal damage but is also the cause of declining renal function.Pregnancy and its unique physiological adaptations are affected by a decrease in the filtration capacity of the kidneys.Preeclampsia is a disorder of the vascular endothelium and is exacerbated by endothelial dysfunction resulting from CKD.Blood pressure targets must be strictly maintained owing to overlapping disease pathogenesis and to minimize cardiovascular damage.Moreover,preexisting renal dysfunction poses a challenge in identifying superimposed preeclampsia,which alters the management strategies in pregnancy.Fetal outcomes in patients with CKD are considerably affected by the presence of hypertension.This review is expected to aid in developing a focused and individualized treatment plan for hypertension in pregnant women with CKD to improve pregnancy outcomes and preserve postpartum renal function.
文摘Objective:To investigate the changes and the corresponding clinical value of serum cortisol levels in patients with hypertensive disorders during pregnancy.Methods:In this study,90 patients with different degrees of hypertensive disorders during pregnancy who were admitted from August 2018 to August 2019 in our hospital were set as the research objects.90 cases were grouped according to the diagnostic criteria in Obstetrics and Gynecology,including 30 cases in each of the hypertension group,the preeclampsia group,and the eclampsia group.Another 30 healthy pregnant women were selected as the control group.The serum cortisol levels of pregnant women in the above four groups were measured.Results:Compared with the control group,the serum cortisol levels in the other three groups were significantly increased.In perinatal outcome,compared with the control group,the three groups of patients had an increase in Apgar score,preterm birth,stillbirth rate,growth restriction rate and neonatal asphyxia rate.There were significant differences between groups(P<0.05),and showed as gestational hypertension<preeclampsia<eclampsia.Conclusion:With the exacerbation of hypertensive disorders during pregnancy,the serum cortisol level continues to increase,which has a serious adverse effect on the prognosis of the perinatal infants.
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To study whether the development of hypertensive disorder complicating pregnancy is associated with --308G→A, -850C→T mutation at promoter of TNF-α gene, the --308G→A, --850C→T polymorphism was examined in patients and healthy pregnant women by PCR-RFLP technique. The frequencies of genotype and allele were compared between the two groups. The results showed that with-308G→A polymorphism distribution, the allele frequency of TNF2 and the frequency of the genotype TNF2/1 in the patient group was significantly higher in the patient group than in control group （P〈0.05）. A significant difference in genotype distribution of --850C→T polymorphism was observed between the two groups. The allele frequencies of T in patient group was higher in the control group as compared with the patient group. The frequencies of CT and TT genotypes were lower in the patient group. It is concluded that the TNF2 allele of -308 is associated with the occurrence of hypertensive disorder complicating pregnancy, while T allele of--850 may be the protective factor against the development of the disease. TNF2/1 CC may be susceptibility genotype of hypertensive disorder complicating pregnancy.

文摘Expression of endogenous ouabain in placenta and the concentrations of serum ET-1 and NO were examined in 30 patients with hypertensive disorder complicating pregnancy （HDCP） and 30 healthy pregnant women to investigate the effect of endogenous ouabain on HDCP. Compared with the healthy pregnant group, the expression of endogenous ouabain dramatically increased in the HDCP groups （P〈0.01）. There was a significantly positive correlation between the expression of en- dogenous ouabain with ET-1 （r= 0.5567, P〈0.01）, while the correlation of endogenous ouabain and NO was significantly negative （r=-0.6895, P〈0.01）. As expected, the correlation between ET-1 and NO was negative （r=-0.7796, P〈0.01）. ET-1 concentrations of maternal and cord sera in HDCP groups were significantly higher in comparison with healthy pregnant group （P〈0.01）. On the contrast, NO concentrations were much lower in the maternal and cord sera of HDCP groups as compared with healthy pregnant group （P〈0.01）. Our data suggest that endogenous ouabain is directly involved in the nosogenesis of HDCP, with accompanying decreased NO and the elevated of ET-1.
文摘Objective： To study the significance of Leptin and the activity of erythrocyte membrane Ca^2＋-ATPase（EMCA） in the development of hypertensive disorder complicating pregnancy. Methods： Radioimmunoassay was used to test the level of serum Leptin, and the activity of EMCA was determined chemically in 38 pregnant women with hypertensive disorder complicating pregnancy and 36 normotensive pregnant women. Results： The level of serum Leptin in hypertensive disorder complicating pregnancy（gestational hypertension： 13.76 ± 3.46 ng/ml; preeclampsia： 15.76 ± 5.47 ng/ml; eclampsia： 18.32 ± 6.38 ng/ml）was significantly higher than that in normotensive pregnant women （11.33 ± 2.93 ng/ml） ,respectively. The average EMCA activity of patients with hypertensive disorder complicating pregnancy （gestational hypertension： 1.65 ± 0.24 μmol·pi/mg.h ; preeclampsia： 1.37 ± 0.19 μ mol·pi/mg·h;eclampsia：1.12 ± 0.14 μmol·pi/mg·h） was significantly lower than that of normotensive pregnant women（1.83 ± 0.38 μ mol·pi/mg·h）,respectively. There was a negative correlation between the level of serum Leptin and the activity of RMCA in hypertensive disorder complicating pregnancy （r = -0.63）. Conclusion： Inhibition of EMCA activity of erythrocyte in hypertensive disorder complicating pregnancy may increase cytoplasmic free calcium, which contributes to the development of hypertensive disorder complicating pregnancy. The negative correlation between the level of serum Leptin and the activity of EMCA, also suggested that serum Leptin and the activity of EMCA may play a role in the development of hypertensive disorder complicating pregnancy.
文摘Objective:To investigate the effect of serum cortisol level on perinatal prognosis in patients with hypertensive disorder during pregnancy.Methods:In this study,different degrees of patients with hypertensive disorder during pregnancy who were admitted from August 2018 to August 2019 in our hospital were selected as the research subjects,and divided into groups according to the severity of the patients’conditions.The 120 patients were divided into gestational hypertension group,preeclampsia group and eclampsia group,with 40 cases each,and another 40 healthy pregnant women were selected.The detection of serum cortisol levels was carried out for the above 4 groups of pregnant women.Results:The serum cortisol level in the control group was(260.35±10.96)nmol/L.The case number of neonatal asphyxia was 1(2.50%),the case number of premature births was 1(2.50%),the number of fetal growth restriction was 1(2.50%),the number of deaths was 0,and the other three groups were higher than this.It showed as gestational hypertension<preeclampsia<eclampsia.The Apgar score of pregnant women in the control group was(9.13±0.29),the ZL index was(1.07±0.07),and the other three groups were lower than this.It showed as gestational hypertension>preeclampsia>eclampsia.There were significant differences between groups(all P<0.05).Conclusion:Early detection of serum cortisol levels in pregnant women is beneficial to timely improve the symptoms of gestational hypertension,thereby suppressing the effects of serum cortisol on perinatal infants and improving the prognosis of newborns.

文摘It has been discovered that the number of hypertensive patients with various types of sleep disorders is on the rise,which significantly increases the morbidity and mortality of cardiovascular diseases.Modern medicine has not reached a consensus on the mechanism and treatment of these diseases but relies on drugs to improve sleep disorders and blood pressure.We regard TCM syndrome differentiation as the breakthrough point,along with comprehensive modern and traditional medical methods based on dialectical thinking as means of holistic and symptomatic treatment of Western medicine integrated with the eight principles of TCM diagnosis,Zang-Fu organs,six meridians,Qi,blood and fluid,as well as other dialectical methods,in order to provide a broader idea for TCM treatment and lay a foundation for further and better development of integrated TCM and Western medicine treatment.

文摘Gestational hypertension(GH)is a common complication during pregnancy.GH is regarded as a potential public health challenge for pregnant women and infants.Limited evidence has linked ambient air pollution to an increased GH risk.However,most of the studies were conducted in developed countries,with inconsistent results obtained.The present study was performed to explore whether exposure to particulate matters with an aerodynamic diameter≤2.5(PM2.5)and ozone(O3)was related to elevated odds of GH in a Chinese population.This population-based cohort study involved 38115 pregnant women in Wuhan,China.All information was collected from the Wuhan Maternal and Child Health Management Information System,using standardized quality control.The daily air pollutant data for PM2.5 and O3 were obtained from the 20 monitoring stations of the Wuhan Environmental Monitoring Center during 2014.The nearest monitor approach was applied to individual exposure assessment of PM2.5 and O3 for each participant.After adjusting for major confounders and other air pollutants,a 10μg/m^3 increase in PM25 and O3 concentrations was found to correlate to a 1.14-fold[95%confidence interval(95%CI):1.09,1.20]and a 1.05-fold(95%CI:1.02,1.07)increase in GH risk,respectively.Additionally,stronger relationships between GH risk and PM25 and O3 exposure were observed in women who conceived in winter and summer,respectively.These findings suggest that air pollutants may contribute to the development of GH.
