Gestational weight gain and pregnancy outcome in women with a history of gestational diabetes mellitus / 中华围产医学杂志

Objective:To explore the association of the total gestational weight gain (GWG) and GWG in different trimesters with adverse pregnancy outcomes during the second pregnancy in women with history of gestational diabetes mellitus (GDM).Methods:This retrospective cohort study recruited 441 singleton pregnant women with a history of GDM who gave birth at Beijing Obstetrics and Gynecology Hospital of Capital Medical University from January 2017 to December 2018 as the GDM history group. Another 1 637 singleton pregnant women without a history of GDM who gave birth at the same period were selected through the mechanical sampling method as the control group. Independent sample t-test and Chi-square test were used to compare the differences in general conditions, GWG and perinatal outcomes between the two groups. Based on the Institute of Medicine guidelines for GWG, the subjects were further divided into three subgroups: inadequate GWG, adequate GWG and excessive GWG groups. Multivariate logistic regression analysis was used to compare the pregnancy outcome in women with the same GWG in different periods of pregnancy between the two groups. Results:(1) Women with GDM history had lower GWG before and after oral glucose tolerance test (OGTT) and the whole pregnancy than those without [(6.3±3.3) vs (7.9±3.7) kg, (4.8±2.6) vs (5.6± 2.6) kg, (11.8±4.6) vs (14.4± 4.6) kg; t=8.074, 5.183, 10.277; all P<0.001]. The incidence of GDM, gestational hypertension, and large for gestational age (LGA) in the GDM history group were higher than those in the control group [46.5% (205/441) vs 18.1% (296/1 637), 8.4% (37/441) vs 5.4% (88/1 637), 12.9% (57/441) vs 9.7% (158/1 637); χ2=153.181, 5.583, 4.013; all P<0.05]. (2) Before OGTT: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI for inadequate, adequate and excessive GWG were 4.02 (2.35-6.88), 3.92 (2.65-5.79) and 3.33 (2.11-5.25), respectively, all P<0.001]. Except for women with inadequate GWG, pregnancy with a history of GDM also had a higher risk of preeclampsia [ OR and 95% CI were 3.62 (1.47-9.23) and 2.22 (1.07-5.57) for adequate and excessive GWG, respectively, both P<0.05]. After OGTT: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI for inadequate, adequate and excessive GWG were 2.48 (1.60-3.84), 4.63 (2.92-7.35) and 4.22 (2.73-6.51), respectively, all P<0.001]. Pregnant women with a history of GDM with excessive GWG had an increased risk of preeclampsia ( OR=2.46, 95% CI: 1.10-5.51, P<0.05). During pregnancy: pregnant women with GDM history of different GWG categories had a higher risk of developing GDM [ OR and 95% CI were 3.02(2.00-4.59), 4.08(2.76-6.04) and 2.66(1.54-4.59) for inadequate, adequate and excessive GWG, respectively, all P<0.001]. Women with GDM history had an increased risk of large for gestational age (LGA) in those with inadequate GWG and postpartum hemorrhage in those with excessive GWG [ OR and 95% CI were 1.94 (1.09-4.21) and 2.93 (1.31-6.55), respectively, both P<0.05]. Conclusions:The total GWG and GWG in different periods during the second pregnancy in women with a history of GDM are lower than those without, but with a higher risk of adverse outcomes. Even in women with the same range of GWG, GDM history still increases the risk of adverse pregnancy outcomes.

Relation of interpersonal adaptation to extraversion and self-control in college students / 中国心理卫生杂志

Objective: To explore the situation of interpersonal adaption and its relation to extroversion and self-control in college students. Methods: Totally 3125 college students (1497 males, 1628 females; age from 16 to24 years) were assessed with the interpersonal adaption dimension from China College Student Adjustment Scale (CCSAS), Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) and Self-Control Scale (SCS). Results: The average score of interpersonal adaption was (33. 3 ± 3. 6). Regression analysis showed that extraversion and self-control positively predicted interpersonal adaption (β = 0. 25, 0. 08), interaction of extraversion and selfcontrol negatively predicted interpersonal adaption significantly (β =-0. 08). In the introvert group, the interpersonal adaption scores were higher in students with higher self-control scores than in those with lower self-control scores (P ＜ 0. 001). Conclusion: It suggests that college students have good interpersonal adaptation. Self-control may buffer the negative effect of low extraversion on interpersonal adaption.

Forensic Pathological Analysis of Maternal Death Cases / 昆明医科大学学报

Objective This study aimed to investigate the characteristics of maternal death cases, the cause of maternal death and the cause of medical dispute,and recommended the relative prevention measures. Methods We retrospectively analyzed 35 cases of maternal death identified in the College of Forensic Medicine in Kunming Medical University from January 2002 to December 2012. Results In 35 maternal death cases: (1) Most maternal deaths are over 30 years old (14 cases, 40%), followed by 17 to 19 years old (6 cases, 17.1%) . And most maternal deaths came from countryside (25 cases,71.4%) . (2) 26 cases maternal deaths happened during the perinatal period (68.5%) . (3) 26 cases happened in county hospitals, township hospitals and informal medical organizations (74.3%) . 5 maternal deaths happened on the way to the hospital or at home (14.3%) . (4) 17 cases died of obstetric hemorrhagic shock (48.6%), 11 cases died of amniotic fluid embolism (31.4%), 2 cases died of amniotic fluid embolism and obstetric hemorrhagic shock (5.7%) . (5) 30 cases of medical disputes were caused by maternal death. Among them, the clinical diagnosis was not consistent with the pathological diagnosis in 20 cases (The misdiagnosis rate was 66.7%) . (6) The causes of medical dispute:clinical diagnosis was unknown in 11 cases (36.7%),11 cases were suspected that rescue was not timely or improper (36.7%),and 8 cases were suspected of misdiagnosis (26.6%) . Conclusion Obstetric hemorrhage and pulmonary amniotic fluid embolism were the main reasons of the maternal death. The incidence of maternal death and medical disputes could be reduced by improving the ability of obstetric staff,and strengthening the diagnosis and treatment about obstetric hemorrhage and pulmonary amniotic fluid embolism. At the same time, women should improve their self-care awareness, reduce early marriage and early pregnancy,and enhance the consciousness of hospital treat and cure.
