Objective To assess and report on the current situation of the families of students, who were involved in the Wenchuan earthquake, to provide data for the government to make decisions that should help with recovery from the earthquake. Methods We selected 2 towns and 4 villages using stratified sampling to take account of different levels of destruction. We performed on-site surveys and secondary research. Results The psychological problems of the parents of the students were serious. These families’ economic situations were not good. Conclusion We should build ‘Mutual Aid’ organization and take the advantage of rural hospitals to promote the long-acting mechanism of the psychological intervention.
Objective To formulate an evidence-based conclusion concerning ultrasound screening for fetal malformations for a pregnant woman after 12 gestational weeks. Methods Based on the clinical problem of whether pregnant women need ultrasound screening for fetal malformations after 11-14 gestational weeks, we used “ultrasound or sonography and prenatal or fetal at first trimester or 11-14 weeks; ultrasound exposure; fetal development” as the keywords and searched The Cochrane Library (Issue 4, 2008), MEDLINE (1981 to 2008), ACP Journal Club (1991 to 2008), and BMJ Clinical Evidence (1999 to 2008) for systematic reviews, randomized controlled trials (RCTs) and controlled clinical trials. The methodological quality of the included studies was assessed to identify the current best evidence. Results Three systematic reviews, two RCTs and ten cohort studies were retrieved. The results showed ultrasound screening detected different fetal malformations in the first, second and third trimester. Not all of the fetal malformations could be detected through prenatal ultrasound screening. Nuchal translucency (NT) measurement as a tool for screening chromosomally abnormal fetuses and detecting fetal malformations by ultrasound proved to be effective if performed within 11-14 gestational weeks. The routine second trimester screening, however, could not be replaced by a detailed ultrasound examination at 11-14 gestational weeks. Most of the trials concluded that the effect of ultrasound on a fetus was not harmful. Conclusion The findings of this study should reassure physicians and parents alike that ultrasound screening is an appropriate option for the pregnant women after 12 gestational weeks.
ObjectiveTo evaluate liver perfusion in pregnant women with hepatitis between 13 and 41 weeks of gestation by three-dimensional color power Doppler angiography (3D-CPA) vascular indexes. MethodsThis study involved 73 pregnant women with hepatitis and 44 healthy pregnant women who had the pregnancy examination between February 2012 and June 2013. We sampled in the area which was near the right lobe of the pregnant women liver's portal vein branch, and obtained the vascularization index (VI), flow index (FI) and vascularization flow index (VFI) via the virtual organ computer-aided analysis (VOCAL) method. Then, we compared the liver perfusion differences between the pregnant women with hepatitis and healthy pregnant women. ResultsThe hepatic flow indexes obtained by 3D-CPA were significantly different between the HBV-DNA viral load and the control groups. The cutoff values of the three vascular indexes of patients with hepatitis with HBV-DNA viral load and the healthy pregnant women were respectively VI=8.760 (P<3×10-4); FI=22.180 (P<6×10-7); and VFI=1.575 (P<3×10-5). ConclusionApplication of the 3D-CPA on liver perfusion may differentiate pregnant women with hepatitis B from normal ones, thus offer a support for clinical prevention and treatment for pregnant women with hepatitis B.
Objective To investigate the incidence of full-term prelabor rupture of membranes (FPROM) and risk factors for FPROM. Methods A prospective nested case-control study was performed on pregnant women in early pregnancy and their spouses, who underwent prenatal examination for the first time in Zhuhai Center for Maternal and Child Health Care from May 2021 to December 2022. Pregnant women with a clear diagnosis of FPROM were included in the case group, and pregnant women without FPROM were randomly selected at a 1∶3 ratio for inclusion in the control group. A questionnaire survey was performed to collect exposure information possibly related to FPROM. The hospital's medical record system was used for information verification and to record the pregnancy outcomes. A multivariate logistic regression analysis was used to investigate the risk factors for FPROM. Results The incidence of FPROM in this study was 24.27%. The multivariate logistic regression analysis showed that obesity pregnant women, smoking, drinking, unbalanced diet, high-intensity physical activity during pregnancy, eating areca nut before pregnancy, using glucocorticoids during pregnancy, older at the time of first pregnancy, a history of adverse pregnancy outcomes, a history of pregnancy complications, a history of diabetes, a history of scar uterus, no folate supplementation during pregnancy, repeated intrauterine operations, polyembryony, polyhydramnios, transverse fetus and fetal cephalopelvic disproportion as the way of conception were risk factors for FPROM (P<0.05). Additionally, the pregnant women whose spouses were obese or smoked or drinking had an increased risk of FPROM (P<0.05). Lower gravidity and lower parity were protective factors against FPROM (P<0.05). Conclusion There are many risk factors for FPROM. Special attention should be given to the life behaviors of pregnant women during pregnancy, and health education should be strengthened for pregnant women and their spouses to help them develop good living habits and reduce the incidence of FPROM.
