The authors studied retrospectively clinical data of seventy cases with breast cancer during pregnancy and lactation.They were treated and diagnosed by operation and pathology.Primary factors influencing prognosis were analyzed.It was demonstrated that 5year survival rate of the patients were significantly influenced by clinical stage , month of pregnancy and lactation, time of symptoms, type of operation, type of pathology, histological grade of malignancy, recurrence and metastasis, and estrogen receptor status (Ｐ＜0.05).Age and termination of pregnancy had no beneficial effect on survival (Ｐ＞0.05).The prognosis of pregnant and lactating breast cancer was poorer than ordinary breast cancer.Their 5year survival rate were 55.7% and 74.3%, respectively. After they were matched for stage and for age, no difference in survival was found.Early diagnosis and radical operation combined with radiotherapy, chemotherapy and hormonal therapy have better prognosis.The method can shorten time of treatment and improve survival rate.Termination of pregnancy has not been shown to improve survival and shall not be advised routinely.Future pregnancy may be detrimental and shall be discouraged.
ObjectiveTo explore whether the vaginal environment changes of pregnant women were correlated with pathogenesis of fungal vaginitis.
MethodsWe selected 166 women in their early pregnancy in the Obstetrics and Gynaecology Clinic between July 2011 and July 2012 as the study objects (excluding fungal vaginitis patients already confirmed). Two important indicators of changes in pH and the amount of vaginal lactobacilli were chosen to determine changes in the vaginal environment. Using prospective study method, by checking changes in the vaginal environment, the objects were divided into two groups: 96 were in the changing environment group, and 70 were in the normal environment group. Sixty seven of them had a pH value lower or equal to 4.0, and 99 higher than 4.0. Fifty-eight of them had a reduced amount of lactobacillus, and 108 had a normal amount of lactobacillus. The rate of fungal vaginitis in each group was counted.
ResultsThe morbidity rate in patients whose pH value was lower than or equal to 4.0 was 17.9% (12/67), while it was 6.1% (6/99) in patients with a pH value higher than 4.0, and the difference was significant (χ2=5.804, P=0.016). The morbidity rate in patients with a reduced amount of lactobacillus was 25.9% (15/58), and it was 2.8% (3/108) in patients with normal lactobacillus, and the difference was also significant (χ2=20.800, P=0.000). The morbidity rate for patients with changing vaginal environment was 16.7% (16/96), and for those with normal environment was 2.9% (2/70), and the difference was significant (χ2=7.985, P=0.005). In those with normal lactobacillus, the reduction of pH value was not correlated with the occurrence of fungal vaginitis (χ2=0.000, P=1.000).
ConclusionThe vaginal environment changes during pregnancy (pH value decrease and Lactobacillus decrease) are associated with the incidence of fungal vaginitis, and it can be prevented and treated based on this phenomenon.
ObjectiveTo investigate the diagnostic value of serum cystatin-C (Cys-C) detection in hypertensive disorder complicating pregnancy patients.
MethodsA hundred patients with pregnancy induced hypertension (PIH) were chosen as the research object from February 2012 to March 2013, and they were divided into mild group, moderate group and severe group according to the severity of the disease. The other 40 healthy pregnant women were selected as the controls (the control group). We compared the four groups in terms of Cys-C, serum urea nitrogen (BUN) and creatinine level, as well as the positive rate of Cys-C, BUN, and creatinine.
ResultsCys-C, BUN, and creatinine in the PIH group were significantly higher than those in the control group (P<0.05). Cys-C and creatinine in preeclampsia mild group were significantly higher than those in the control group (P<0.05), but BUN level between the two was not statistically significant (P>0.05). Cys-C, BUN, and creatinine in the PIH moderate and severe groups were significantly higher than those in the control group (P<0.05). The abnormal rate of Cys-C in the PIH mild group was significantly higher than that of Cys-C and creatinine (P<0.05).
ConclusionCys-C, BUN and creatinine can all show renal damage in PIH patients, but the Cys-C value in early diagnosis is better than that of BUN and creatinine. It can be used as a monitoring index of pregnancy-induced hypertension prevention and early treatment.
ObjectivesTo systematically review the correlation between maternal serum selenium levels during pregnancy and premature birth.MethodsDatabases including PubMed, The Cochrane Library, EMbase, Web of Science, CNKI and CBM were searched to collect studies on correlation between maternal serum selenium levels during pregnancy with preterm birth in the offspring from inception to January, 2020. Two reviewers independently screened literature, extracted data and evaluated risk of bias of the included literature. Then, meta-analysis was conducted by using RevMan 5.3 software.ResultsA total of 12 studies involving 2 484 patients were included. The results of meta-analysis showed that compared with control group, the preterm group had lower serum selenium levels in pregnant females (SMD=?0.89, 95%CI ?1.56 to ?0.22, P=0.01). The results of the subgroup analysis showed that heterogeneity among subjects was still large when grouped accorcding to the continent to which a country belongs, the time of blood sample collection and test method in pregnant females.ConclusionsLow maternal serum selenium levels during pregnancy may increase the risk of preterm birth. Due to the limitation of the quantity and quality of the included studies, the above conclusions are required to be verified by more high quality studies.
ObjectiveTo systematically review the safety of low molecular weight heparin (LMWH) in pregnancy. MethodsPubMed, EMbase, The Cochrane Library, WanFang Data, VIP, and CNKI databases were electronically searched to collect randomized controlled trials (RCTs) and cohort studies on the safety of LMWH in pregnancy from inception to March 30th, 2020. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 77 RCTs and 13 cohort studies were included. The results of meta-analysis showed that LMWH increased the incidence of postpartum hemorrhage (RR=1.50, 95%CI 1.00 to 2.25, P=0.05). However, there was no significant difference. The incidence of hematological adverse events was different from the results of RCTs and cohort studies. The results of RCT subgroup analysis showed that LMWH increased ecchymosis at the injection site (RR=1.60, 95%CI 1.24 to 2.08, P=0.000 4). However, the incidence of overall skin system adverse events did not increase significantly. LMWH reduced the incidence of cardiovascular adverse events (RR=0.18, 95%CI 0.07 to 0.46, P=0.000 3). LMWH failed to increase the occurrence of fetal congenital malformations, digestive system, central nervous system, skeletal system, and systemic adverse events. ConclusionsCurrent evidence suggests that LMWH is relatively safe to use during pregnancy. However, whether it increases postpartum hemorrhage and hematological adverse events is unclear. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
ObjectiveTo systematically review the prevalence rate of gestational diabetes mellitus in Chinese population.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect relevant literature of the prevalence rate of gestational diabetes in Chinese population from inception to October 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using R 3.4.1 software.ResultsA total of 27 studies were included involving 183 338 peoples, of whom 23 834 were diagnosed as gestational diabetes mellitus by oral glucose tolerance test (75g). The prevalence rate was 13% (95%CI 10 to 16). The prevalence rate of gestational diabetes mellitus in north area was 13% (95%CI 9 to 19), central area was 11% (95%CI 2 to 39), east area was 15% (95%CI 12 to 19), south area was 12% (95%CI 11 to 14), northwest area was 5% (95%CI 3 to 8) and southwest area was 4% (95%CI 3 to 4). The prevalence rate of gestational diabetes mellitus during January 2005 to December 2012 was 11% (95%CI 7 to 16), during December 2012 to June 2016 was 17% (95%CI 14 to 20). The prevalence of specialist hospitals was 9% (95%CI 6 to 14), and which of comprehensive hospital was 14% (95%CI 11 to 18). The prevalence of gestational diabetes screening at 24 to 28 weeks gestation remained at 13% (95%CI 10 to 17).ConclusionThe prevalence rate of gestational diabetes mellitus is high in China. The prevalence rate of gestational diabetes mellitus in north China, central China and east China is significantly higher than that in southern China, northwest China and southwest China. The prevalence rate during 2012-2016 is significantly higher than that in 2005 to 2012. Improvement of lifestyle and living standard should be considered be closely related with that. The prevalence of comprehensive hospitals is higher than specialist hospitals. It is related to the China’s economic conditions, medical care situations and the medical habits of patients.
ObjectiveTo systematically review the relationship between maternal alcoholic consumption during pregnancy and the occurrence of childhood cancer in offspring. MethodsThe PubMed, Embase, Web of Science, Cochrane library, CNKI, WanFang Data, VIP, and CBM databases were electronically searched to obtain related case-control and cohort studies from inception to December 2024. Two reviewers independently screened articles, extracted data and assessed the risk of bias of the included articles. Meta-analysis was performed by using the RevMan 5.4 software. ResultsA total of 18 articles involving 9 childhood tumors' outcome were included. The results of meta-analysis showed that compared with women who never drink alcohol during pregnancy, alcoholic consumption during pregnancy increased the incidence risk of childhood cancer (OR=1.13, 95%CI 1.01 to 1.26, P=0.04). Subgroup analysis showed that alcoholic consumption during pregnancy significantly increased the incidence risk of acute leukemia (OR=1.17, 95%CI 1.06 to 1.30, P=0.002) and acute lymphocytic leukemia (OR=1.23, 95%CI 1.02 to 1.48, P=0.03). ConclusionThe current evidence suggests that alcoholic consumption during pregnancy significantly increases the incidence risk of childhood cancer in offspring, particularly acute leukemia and acute lymphocytic leukemia. Due to the limited quantity and quality of the included articles, more high-quality birth cohort studies are needed to verify the above conclusion.
ObjectiveTo systematically review the clinical efficacy and effects on pregnancy outcomes of S-adenosy-L-methionine combined with ursodesoxycholic acid in the treatment of intrahepatic cholestasis of pregnancy.
MethodsDatabases such as PubMed, The Cochrane Library, CNKI, VIP, WanFang Data were searched for the studies about the clinical efficacy and effects on pregnancy outcomes of S-adenosy-L-methionine combined with ursodesoxycholic acid in the treatment of intrahepatic cholestasis of pregnancy up to December 31st, 2013. Two reviewers independently screened literature, extracted data and evaluated methodological quality. Then meta-analysis was conducted using RevMan 5.0.24 software.
ResultsA total of 11 RCTs involving 776 patients were included. The results of meta-analysis showed that, combined medication reduced blood biochemical indexes inlcuding ALT (MD=3.63, 95%CI 0.63 to 6.64, P=0.02), TB (MD=3.70, 95%CI 1.45 to 5.96, P=0.001), and AST (MD=7.61, 95%CI 2.47 to 12.75, P=0.004). Combined therapy significantly decreased the rates of amniotic fluid contamination (OR=0.29, 95%CI 0.19 to 0.45, P=0.000 01), cesarean section (OR=0.53, 95%CI 0.36 to 0.79, P=0.002), postpartum hemorrhage (OR=0.32, 95%CI 0.12 to 0.90, P=0.03), preterm birth (OR=0.36, 95%CI 0.24 to 0.55, P < 0.000 01), fetal distress (OR=0.33, 95%CI 0.19 to 0.58, P=0.000 1) and neonates asphyxia (OR=0.30, 95%CI 0.19 to 0.47, P < 0.000 01). Combined therapy was also beneficial to improving pruritus symptoms (MD=0.20, 95%CI 0.08 to 0.31, P=0.000 08) and benefiting fetus growth (MD=0.45, 95%CI 0.23 to 0.66, P < 0.000 1).
ConclusionThe combination of S-adenosy-L-methionine and ursodesoxycholic acid is superior to ursodesoxycholic acid alone in improving clinical symptoms and pregnant outcomes of patients with intrahepatic cholestasis of pregnancy.
