ABSTRACT
Objective To explore the feasibility of excluding oral 75 g glucose tolerance test (OGTT)in pregnant women with fasting plasma glucose (FPG) ＜4.4 mmol/L in middle and late trimester.Methods From February 1,2012 to August 31,2013,18 851 pregnant women without pre-gestational diabetes mellitus who received 75 g OGTT in Maternal and Child Health Hospital of Hubei Province,China,at 24-28 weeks of gestation were enrolled.The criteria for gestational diabetes mellitus (GDM) were FPG ＞5.1 mmol/L and/or 1 h plasma glucose ＞10.0 mmol/L and/or 2 h plasma glucose ＞8.5 mmol/L in OGTT.The values of FPG in predicting GDM were analyzed with receiver operating characteristic (ROC) curve.The differences of detection rates for GDM among women of different ages,women with different FPG levels,and those with or without risk factors of GDM were compared by x2 test and Fisher's exact test.Results The overall detection rate of GDM was 9.11％(1 718/18 851).The detection rate of GDM was lower in women aged ＜ 25 years than women aged 25-,30-and ≥ 35 years [4.77％ (137/2 875) vs 7.76％ (803/10 350),12.43％ (552/4 440)and 19.06％ (226/1 186),respectively,x2=30.53,120.24 and 210.66,all P＜0.01].The sensitivity and specificity were 55％ and 68％,respectively,when the cutoff value of FPG was 4.4 mmol/L,and the Youden index was 0.23 and the area under the ROC curve was 0.61 (95％CI:0.59-0.63,P＜0.01).The sensitivity and specificity were 40％ and 80％,respectively,when the cutoff value was 4.5 mmol/L,and the Youden index was 0.20 and the area under the ROC curve was 0.61 (95％CI:0.59-0.63,P＜0.01).The missed diagnosis rate was lower when the cutoff point of FPG was defined as 4.4 mmol/L.The detection rate for GDM was 3.45％ (384/11 121) in women with FPG ＜4.4 mmol/L,significantly lower than in those with FPG ≥ 4.4 but ＜5.1 mmol/L and ≥ 5.1 mmol/L [8.06％ (561/6 957) and 100.00％ (773/773),x2=183.66 and 7 672.08,all P＜0.01].When FPG was ＜4.4 mmol/L or ≥ 4.4 but ＜5.1 mmol/L,the detection rate for GDM was significantly higher in women with GDM risk factors than in those without [5.09％ (118/2 318) and 10.75％ (184/1 712) vs 3.02％ (266/8 803) and 7.19％ (377/5 245),x2=23.56 and 22.06,P＜0.01].Conclusion OGTT may not be included in GDM screening in the pregnant women with FPG＜4.4 mmol/L and without GDM risk factors in the areas lack of medical resources.
ABSTRACT
Objective To discuss clinical effect of anti-inflammatory No.1 on prevention and treat-ment of chemotherapeutic phlebitis. Methods 200 patients undergoing peripheral venous chemotherapy were divided into the observation group and the control group with 100 patients in each group. The control group received routine nursing, the observation group was given local compression with gauze dipped with anti-inflammatory No.1 agents. The incidence of phlebitis was compared between the two groups and un-derwent χ2 test. Results The incidence of phlebitis in the observation group was lower than that of the control group. Conclusions Application of local compression with anti-inflammatory No.1 agents proves to be an effective method in prevention and treatment of chemotherapeutic phlebitis.
