ObjectivesTo systematically review the association between pregnancy-induced hypertension (PIH) and preterm birth in mainland China.MethodsPubMed, The Cochrane Library, ScienceDirect, Web of Science, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on the association between PIH and preterm birth in mainland China from January, 2007 to March, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 48 studies were included, involving 43 276 cases of premature birth, 527 995 cases of full-term control group, in which there were 3 446 cases of PIH in premature delivery, with a prevalence rate of 7.96%. There were 14 099 cases of PIH in the full-term control group, with a prevalence rate of 2.67%. The results of meta-analysis showed that PIH was associated with preterm birth (OR=3.27, 95%CI 2.64 to 4.05, P<0.001). The overall population attributable risk was 13.0%. Subgroup analysis was conducted for different study types, and the results were unaltered.ConclusionsThe current evidence shows that PIH is associated with preterm birth. During pregnancy, the management and intervention of pregnant females with gestational hypertension should be strengthened, and active treatment should be supervised to prevent the occurrence of premature birth.
Abstract: Objective To investigate the anticoagulation effect of warfarin on pregnant women with prosthetic mechanical heart valves during the whole course of pregnancy and their fetuses. Methods Followup survey was carried out on 103 pregnant women with prosthetic mechanical heart valves treated in the Second Xiangya Hospital of Central South University from April 1998 to June 2010. Their age ranged from 19 and 38 years (26.4±3.8 years). All the 103 pregnant women were given oral administration of warfarin during the whole course of pregnancy. The average dose of domestic warfarin was 3.30±0.43 mg/d (87 cases), while the average dose of imported warfarin was 2.90±1.05 mg/d (16 cases). Results None of the patients suffered from serious embolic events. One patient suffered from spontaneous peritoneal hemorrhage. There were 4 cases of intrauterine deaths, and 5 cases of fetal malformation including 1 case of Down’s syndrome and 4 cases of hydrocephalus. Six cases of low birth weight infants and 1 case of ABO hemolytic disease were also found. All the other neonates were healthy with normal weight. No pregnant women suffered from postpartum hemorrhage. Conclusion Oral administration of low dose warfarin (lt;5 mg/d) during the whole course of pregnancy is a relative safe and effective anticoagulation protocol.
ObjectivesTo systematically review the perinatal outcomes after laparoscopic myomectomy versus transabdominal myomectomy.MethodsPubMed, Web of Science, Elsevier, The Cochrane Library, CNKI, VIP and WanFang Data databases were searched from inception to July 2017, to collect randomized controlled trials or cohort studies comparing the perinatal outcomes after laparoscopic myomectomy and transabdominal myomectomy. Two reviewers independently screened literature, extracted data and assessed the risk of bias of include studies. Meta-analysis was then performed by RevMan 5.3 software.ResultsEight randomized controlled trials, twenty-one cohort studies involving 4357 patients were included. The results of meta-analysis showed that: the premature birth rate (OR=0.60, 95%CI 0.38 to 0.95, P=0.03) in the laparoscopic myomectomy was lower than that in the laparotomy group. However, the rate of uterine rupture during pregnancy (OR=3.19, 95%CI 1.29 to 7.89, P=0.01) in the laparoscopic myomectomy was higher than that in the laparotomy group. There were no significant differences between two groups in the myoma residual (OR=1.00, 95%CI 0.37 to 2.65, P=0.99), recurrence (OR=0.92, 95%CI 0.68 to 1.25, P=0.60), abortion (OR=0.90, 95%CI 0.63 to 1.28, P=0.56), ectopic pregnancy (OR=1.11, 95%CI 0.54 to 2.26, P=0.78), pregnancy rate (OR=1.06, 95%CI 0.89 to 1.27, P=0.52), cesarean (OR=0.82, 95%CI 0.57 to 1.19, P=0.31), and pregnancy complications (OR=0.84, 95%CI 0.45 to 1.59, P=0.60).ConclusionsCurrent evidence shows that there are no significant differences between two groups in the myoma residual, myoma recurrence, abortion, ectopic pregnancy, pregnancy rate, cesarean and pregnancy complications. While the rate of uterine rupture during pregnancy in the laparoscopic myomectomy is higher than that in the laparotomy group, the premature birth rate after operation in the laparoscopic myomectomy is lower and shorter than that in the laparotomy group. Due to the limited quantity and quality of the included studies, more high quality studies are required to verify the above conclusion.
ObjectivesTo explore the association between liver dysfunction and premature birth (PTB).MethodsA prospective cohort of HBV-infected or uninfected pregnant women of Han nationality attending antenatal care at Nantong Maternal and Child Health Hospital was recruited from January 1st, 2012 to June 30th, 2016. Liver function tests (LFTs) were monitored through pregnancy. Robust Poisson regression was used to estimate adjusted risk ratios (RRs) on HBV infection and LFT abnormalities.ResultsAmong 35 452 pregnant women (1 073 HBV carriers and 34 379 non-HBV women), 4 266 (12.03%) had at least one instance of abnormal LFT results. One fold upper limit of normal aspartate aminotransferase (AST), two folds upper limit of normal total bilirubin, and four folds upper limit of normal total bile acid rather than HBsAg positivity, were identified as independent risk factors for PTB by Robust Possion regression analysis.ConclusionsAbnormal LFTs among pregnant women is an independent risk factor of PTB. We suggest monitoring the LFTs results of high-risk population throughout pregnancy.
With the opening of the two child policy in China, the number of pregnant women has increased. Pregnancy has a huge impact on the cardiovascular system, and heart disease during pregnancy increases the risk of maternal heart failure and death, intrauterine growth retardation, and the risk of complications such as premature birth. Pregnancy with heart disease ranks first among indirect obstetric deaths in China. Reducing maternal mortality is a global goal of the World Health Organization. Thus, to strengthen the prevention and management of patients with critical heart disease during pregnancy is important. However, clinical decision-making and management of pregnant women with heart disease is still controversial. This article combines relevant literature of pregnancy and heart disease published in recent years and reviews of relevant diagnostic and therapeutic methods, to provide clinical reference for pregnant women with heart disease preventive care and management of the whole strategy.
Objective To summarize the recent studies on diagnosis and treatment for pregnancy-associated breast cancer （PABC） to provide evidence for diagnosis and treatment for PABC. Methods By PubMed， Medline， and CNKI retrieval system， with “pregnancy-associated breast cancer or PABC， diagnosis of pregnancy-associated breast cancer or PABC， treatment of pregnancy-associated breast cancer or PABC” as key words to retrieval for the recent researches about PABC. All of the publications about studies on diagnosis and treatment for PABC were reviewed and summarized. Results Diagnosis of PABC included ultrasound， mammography， magnetic resonance imaging， needle biopsy， and so on， and the treatment contained surgery， chemotherapy， endocrine therapy， radiation therapy， and targeted therapy. However， when diagnosis and treatment for PABC involved， the impact to patients with pregnancy and fetus must be considered in priority. Conclusions By reviewing the studies of relevant papers about diagnosis and treatment for PABC which can provide a clinical guidance for clinicians. Usage of bevacizumab and lapatinib still needs to further be studied.
Objective To summarize our diagnostic and treatment experience for patients with acute Stanford type A aortic dissection （AAAD） during pregnancy. Methods Clinical data of 3 AAAD gravida （age of 30，32，35） who received surgical treatment in Beijing Anzhen Hospital of Capital Medical University from May 2008 to July 2010 were retros-pectively analyzed. One gravida received Sun’s procedure （total arch replacement combined with stented elephant trunk implantation） 3 days after cesarean section，but the fetus died in the uterus. Another gravida successfully underwent Bentall procedure and Sun’s procedure immediately after cesarean section and hysterectomy. The third gravida received cesarean section with the uterus in situ followed by ascending aorta replacement and Sun’s procedure. Results All the 3 puerperasrecovered uneventfully，and the 2 newborns of the second and third puerperas also lived well. The 3 puerperas were followedup for 6 months after discharge. CT scan showed organized thrombus in the aortic false lumen. During follow-up，the 3 puerperas recovered well，and the 2 infants had normal growth and development. Conclusions Management principles of AAAD during pregnancy firstly include timely and accurate diagnosis，which is of prime importance. Secondly，gravidas’hemodynamics should maintain stable. Thirdly，intraoperative hemorrhage should be satisfactorily controlled. Lastly，multi-modality treatment is very important to improve the prognosis of both gravidas and fetuses.
Inflammatory bowel disease (IBD) is a group of chronic, recurrent, and non-specific intestinal inflammatory diseases. It usually occurs between 20 and 40 years old, overlapping with the patient’s childbearing age. Active IBD may lead to decreased fertility and adverse pregnancy outcomes, and pregnancy may also lead to recurrence of IBD. Through studying domestic and foreign related literature on pregnancy and IBD, this article elaborates on the guidance and management of IBD before pregnancy, the disease management of IBD during pregnancy, the disease management of IBD during lactation, and the current status and prospects of traditional Chinese medicine treatment. It aims to provide references for patients and clinicians to have a more scientific understanding of pregnancy with IBD.
Currently, cardiac arrest has become a major public health problem, which has a high incidence rate and a high mortality rate in humans. With the continuous advancement of cardiopulmonary resuscitation techniques, the overall prognosis of cardiac arrest victims is gradually improved. However, cardiac arrest events under special circumstances are still serious threats to human health. This article reviews the progress of epidemiology, pathogenesis, treatment characteristics, and key points of cardiopulmonary resuscitation in those special cardiac arrest events associated with trauma, poisoning, drowning and pregnancy.
ObjectiveTo explore the pathogenesis of acute pancreatitis during pregnancy, differential diagnosis, and standardized treatment. MethodsThe related literatures at home and abroad in recent years were reviewed, and the progress of pathogenesis and treatment of acute pancreatitis during pregnancy were summarized. ResultsThe common cause of acute pancreatitis during pregnancy include biliary system diseases, hyperlipidemia, hyperparathyroidism, the direct effect of pregnancy on the pancreas, etc. According to the different pathogenic factors of acute pancreatitis during pregnancy, the laparoscopic cholecystectomy (LC), endoscopic retrograde cholangiopancreatography (ERCP), low-fat diet combined with Omega-3 fatty acids, parathyroid adenoma resection, or terminal pregnancy could be use. ConclusionAcute pancreatitis during pregnancy is dangerous, the cause, general condition of patients, and the growth of fetus should be give full consideration, and the diagnosis and treatment are standardized.
