Importance Induction of labor (IOL) is a common obstetric intervention that stimulates the onset of labor using artificial methods. Objective The aim of this study was to summarize and compare recommendations from 4 national or international medical societies on the IOL. Evidence Acquisition A descriptive review was conducted of major published guidelines on IOL: the American College of Obstetricians and Gynecologists' “Induction of Labor” and “Management of Late-Term and Postterm Pregnancies,” the guidelines of the Society of Obstetricians and Gynaecologists of Canada (SOGC) on “Induction of Labour,” those of the National Institute for Health and Care Excellence (NICE) on “Inducing Labour,” and the World Health Organization's (WHO's) “Recommendations for Induction of Labour” and “WHO Recommendations: Induction of Labour at or Beyond Term.” These guidelines were compared in terms of their recommendations on clinical indications and methods. Results Many similar indications and contraindications to IOL are identified between American College of Obstetricians and Gynecologists and SOGC, whereas NICE and WHO do not mention any contraindications. The timing of IOL in postterm pregnancies also differs among the guidelines. Regarding the methods of induction, all the medical societies recommend the use of membrane sweeping, mechanical methods, prostaglandins, and oxytocin, whereas NICE argues against the use of misoprostol for IOL. The American College of Obstetricians and Gynecologists and SOGC consider amniotomy a method of IOL, whereas NICE and WHO do not recommend it. All the guidelines also make similar recommendations regarding the management of uterine tachysystole in cases of IOL. Conclusions The World Health Organization seems to be the most evidence-based guideline with recommendations based mainly on Cochrane reviews. The variation in the clinical indications and methods of IOL highlights the need to adopt an international consensus, which may help to optimize the quality of obstetric care and further promote evidence-based medicine. Target Audience Obstetricians and gynecologists, family physicians. Learning Objectives After participating in this activity, the learner should be better able to identify the appropriate indications for induction of labor; explain the effectiveness and associated risks of using prostaglandins, misoprostol, oxytocin, and amniotomy for induction of labor; and assess the definition and alternatives of failure of induction of labor.

Importance: Gestational diabetes mellitus (GDM) represents one of the most frequent complications of pregnancy and is associated with increased maternal and neonatal morbidity. Its incidence is rising, mostly due to an increase in maternal age and maternal obesity rate.Objective: The aim of this study was to review and compare the recommendations of the most recently published guidelines on the diagnosis and management of this condition.Evidence Acquisition: A descriptive review of guidelines from the National Institute for Health and Care Excellence (NICE), the International Federation of Gynecology and Obstetrics, the Australasian Diabetes in Pregnancy Society (ADIPS), the Society of Obstetricians and Gynecologists of Canada (SOGC), the American College of Obstetricians and Gynecologists (ACOG), the American Diabetes Association, and the Endocrine Society on gestational diabetes mellitus was carried out.Results: The NICE guideline recommends targeted screening only for women with risk factors, whereas the International Federation of Gynecology and Obstetrics, ADIPS, SOGC, and the ACOG recommend screening for all pregnant women at 24 to 28 weeks of gestation in order to diagnose and effectively manage GDM; they also state that women with additional risk factors should be screened earlier (ie, in the first trimester) and retested at 24 to 28 weeks, if the initial test is negative. These guidelines describe similar risk factors for GDM and suggest the same thresholds for the diagnosis of GDM when using a 75-g 2-hour oral glucose tolerance test. Of note, the NICE only assesses the fasting and the 2-hour postprandial glucose levels for the diagnosis of GDM. Moreover, the SOGC and the ACOG do not recommend this test as the optimal screening method. The Endocrine Society alone, on the other hand, recommends the universal testing of all pregnant women for diabetes before 13 weeks of gestation or as soon as they attend the antenatal service and retesting at 24 to 28 weeks if the initial results are normal. In addition, there is a general consensus on the appropriate ultrasound surveillance of pregnancies complicated with GDM, and all the medical societies, except the ADIPS, recommend self-monitoring of capillary glucose to assess the glycemic control and set the same targets for fasting and postprandial glucose levels. There is also agreement that lifestyle modifications should be the first-line treatment; however, the reviewed guidelines disagree on the medical management of GDM. In addition, there are controversies regarding the timing of delivery, the utility of hemoglobin A 1c measurement, and the postpartum and lifelong screening for persistent hyperglycemia and type 2 diabetes. However, all the guidelines state that all women in pregnancies complicated by GDM should
