Question:
Prevalence of diabetes (and gestational diabetes) in pregnancy
Answer:
7%; 86% gestational
Question:
Prevalence of gestational diabetes: least common in ..
Answer:
Causcasian women
Question:
Prevalence of gestational diabetes: most common in ..
Answer:
Hispanic, African American, Native American, and Asian or Pacific Islander women same risk factors
seen for type 2 diabetes such as obesity and increased age
Question:
Maternal complications of gestational diabetes
Answer:
higher risk of developing preeclampsia (especially above 115 fasting gluscose), undergoing a cesarean
delivery, developing diabetes (predominantly type 2 diabetes) later in life.
Question:
Fetal complications of gestational diabetes
Answer:
increased risk of macrosomia, neonatal hypoglycemia, hyperbilirubinemia, shoulder dystocia, and
birth trauma
Question:
Screening for most individuals who are pregnant between X weeks
Answer:
24-28 weeks
, Question:
Screening earlier than 24-28 weeks in patients with the following risk factors
Answer:
overweight and obese women (BMI > 25 unless Asian Americans >23) with additional diabetic risk
factors, including those with a prior history of GDM. However, the best test for early GDM or type 2
diabetes screening is not clear. Overweight with additional risk factor
-inactivity
-high risk race/ethnicity
-1st degree relative with diabetes
-previous history
-hypertension
-PCOS
-high cholesterol
-macrosomic baby previously
-A1c > 5.7
Possibly consider 75 g 2 hr testing; but not strong recommendation from ACOG
Question:
Routine glucose challenge and OGTT (oral glucose tolerance testing)at 24-28 weeks
Answer:
50-g oral glucose solution followed by a 1-hour venous glucose determination. Women whose glucose
levels meet or exceed an institution's screening threshold then undergo a 100-g, 3-hour diagnostic
OGTT. Gestational diabetes mellitus is most often diagnosed in women who have two or more
abnormal values on the 3-hour OGTT.
Question:
Discussed range of positive threshold values for 1 hr glucose 50 g testing
Answer:
130 - 140 Depends on the institution
Question:
plasma vs serum
Answer:
plasma: leftover when blood has clotted serum: leftover when blood is anticoagulated
Question:
Serum and plasma glucose level Carpenter and Coustan conversion
Answer:
180, 155, 144, 95
