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 A1c 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 undergo a glycemic test at around 6 to 12 weeks after delivery. Finally, there is a universal consensus on the importance of breastfeeding and preconception screening before future pregnancies. Conclusions: As GDM is an increasingly common complication of pregnancy, it is of paramount importance that inconsistencies between national and international guidelines should encourage research to resolve the issues of controversy and allow uniform international protocols for the diagnosis and management of GDM, in order to safely guide clinical practice and subsequently improve perinatal and maternal outcomes. Target Audience: Obstetricians and gynecologists, family physicians Learning Objectives: After participating in this activity, the learner should be better able to identify all available screening methods for gestational diabetes mellitus; describe diagnostic procedures for gestational diabetes mellitus; and explain appropriate management issues during the antenatal, intrapartum, and postpartum period in pregnancies complicated by gestational diabetes mellitus.

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: Postpartum hemorrhage (PPH) is a common complication of childbirth and the leading cause of maternal deaths worldwide, also associated with important secondary sequelae. Objective: The aim of this study was to review and compare the most recently published influential guidelines on evaluation, management, and prevention of this severe, life-threatening obstetric complication. Evidence Acquisition: A descriptive review of guidelines from the American College of Obstetricians and Gynecologists, the Royal College of Obstetricians and Gynecologists, the Royal Australian and New Zealand College of Obstetricians and Gynecologists, the Society of Obstetricians and Gynecologists of Canada, the Network for the Advancement of Patient Blood Management, Hemostasis and Thrombosis in collaboration with the International Federation of Gynecology and Obstetrics, the European Board and College of Obstetrics and Gynecology and the European Society of Anaesthesiology, and the World Health Organization on PPH was carried out. Results: There is a consensus among the reviewed guidelines that once PPH occurs, it is important to identify the underlying cause (4 T's), estimate the blood loss, and immediately initiate a resuscitation protocol with fluid replacement, blood transfusion, and close monitoring of the woman. In case of uterine atony, all the reviewed medical societies recommend uterine massage, bimanual uterine compression, and administration of uterotonics, although minor discrepancies are observed regarding the optimal regimens. If these measures fail, the use of intrauterine balloon tamponade or other surgical interventions is unanimously recommended. There is also agreement regarding the management of PPH due to retained placenta, placenta accreta, obstetric trauma, uterine rupture or inversion, and acute coagulopathy. Massive transfusion protocols are not consistent in the reviewed guidelines. Finally, all guidelines highlight the importance of the active management of the third stage of labor for the prevention of PPH, suggesting several interventions, with the administration of oxytocin being the criterion standard. Conclusions: Postpartum hemorrhage is a significant contributor of maternal morbidity and mortality. Thus, the development of consistent international practice protocols for the effective management and prevention of this major complication seems of paramount importance and will hopefully improve obstetric outcomes and especially maternal mortality rate. Target Audience: Obstetricians and gynecologists, family physicians. Learning Objectives: After participating in this activity, the learner should be better able to explain the definition of postpartum hemorrhage, as well as the initial maternal evaluation; describe the appropriate management of postpartum hemorrhage; and assess the risk factors and adopt strategies for the prevention of postpartum hemorrhage.

Background/Objectives: Inflammation, infections, and oxidative stress (OS) all have an impact on male infertility, which is a complicated, multifaceted illness. OS affects motility and fertilization capability. It accomplishes this through damaging sperm DNA, oxidizing proteins, and triggering lipid peroxidation. These effects occur due to an imbalance between reactive oxygen species (ROS) and antioxidant defenses. Methods: This review aims to evaluate the impact of oxidative stress and inflammation on male infertility by assessing recent literature. Results: Pro-inflammatory cytokines, like TNF-α and IL-6, interfere with spermatogenesis and promote oxidative damage. Additionally, infections caused by pathogens like Escherichia coli and Chlamydia trachomatis alter the reproductive microenvironment, leading to sperm dysfunction and inflammation. Conclusions: Early detection and targeted treatment are essential due to the intricate interactions among these elements. Microbiota-modulating techniques, antimicrobial therapies, anti-inflammatory drugs, and antioxidants are therapeutic approaches that may help reduce oxidative damage and enhance male fertility.

Importance: Gestational hypertension and preeclampsia are leading causes of maternal and perinatal morbidity and mortality worldwide. Τhe lack of effective screening and management policies appears to be one of the main reasons. Objective: The aim of this study was to review and compare recommendations from published guidelines on these common pregnancy complications. Evidence Acquisition: A descriptive review of guidelines from the National Institute for Health and Care Excellence, the Society of Obstetric Medicine of Australia and New Zealand, the International Society of Hypertension, the International Society for the Study of Hypertension in Pregnancy, the European Society of Cardiology, the International Federation of Gynecology and Obstetrics, the Society of Obstetricians and Gynaecologists of Canada, the American College of Obstetricians and Gynecologists, the International Society of Ultrasound in Obstetrics and Gynecology, the World Health Organization, and the US Preventive Services Task Force on gestational hypertension and preeclampsia was carried out. Results: There is an overall agreement that, in case of suspected preeclampsia or new-onset hypertension, blood and urine tests should be carried out, including dipstick test for proteinuria, whereas placental growth factor–based testing is only recommended by the National Institute for Health and Care Excellence and the European Society of Cardiology. In addition, there is a consensus on the recommendations for the medical treatment of severe and nonsevere hypertension, the management of preeclampsia, the appropriate timing of delivery, the optimal method of anesthesia and the mode of delivery, the administration of antenatal corticosteroids and the use of magnesium sulfate for the treatment of eclamptic seizures, the prevention of eclampsia in cases of severe preeclampsia, and the neuroprotection of preterm neonates. The reviewed guidelines also state that, based on maternal risk factors, pregnant women identified to be at high risk for preeclampsia should receive low-dose aspirin starting ideally in the first trimester until labor or 36 to 37 weeks of gestation, although the recommended dose varies between 75 and 162 mg/d. Moreover, most guidelines recommend calcium supplementation for the prevention of preeclampsia and discourage the use of other agents. However, controversy exists regarding the definition and the optimal screening method for preeclampsia, the need for treating mild hypertension, the blood pressure treatment targets, and the postnatal blood pressure monitoring. Conclusions: The development and implementation of consistent international protocols will allow clinicians to adopt effective universal screening, as well as preventive and management strategies with the intention of improving maternal and neonatal outcomes. Target Audience: Obstetricians and gynecologists, family physicians Learning Objectives: After participating in this activity, the physician should be better able to define gestational hypertension and preeclampsia; identify the risk factors and explain available screening methods for preeclampsia; and describe the recommended antenatal, intrapartum, and postnatal care of women with gestational hypertension or preeclampsia.

Hypoglycemia represents one of the most frequent metabolic disturbances of the neonate, associated with increased morbidity and mortality, especially if left untreated or diagnosed after the establishment of brain damage. The aim of this study was to review and compare the recommendations from the most recently published influential guidelines on the diagnosis, screening, prevention and management of this common neonatal complication. Therefore, a descriptive review of the guidelines from the American Academy of Pediatrics (AAP), the British Association of Perinatal Medicine (BAPM), the European Foundation for the Care of the Newborn Infants (EFCNI), the Queensland Clinical Guidelines-Australia (AUS), the Canadian Pediatric Society (CPS) and the Pediatric Endocrine Society (PES) on neonatal hypoglycemia was carried out. There is a consensus among the reviewed guidelines on the risk factors, the clinical signs and symptoms of NH, and the main preventive strategies. Additionally, the importance of early recognition of at-risk infants, timely identification of NH and prompt initiation of treatment in optimizing the outcomes of hypoglycemic neonates are universally highlighted. All medical societies, except PES, recommend screening for NH in asymptomatic high-risk and symptomatic newborn infants, but they do not provide consistent screening approaches. Moreover, the reviewed guidelines point out that the diagnosis of NH should be confirmed by laboratory methods of BGL measurement, although treatment should not be delayed until the results become available. The definition of NH lacks uniformity and it is generally agreed that a single BG value cannot accurately define this clinical entity. Therefore, all medical societies support the use of operational thresholds for the management of NH, although discrepancies exist regarding the recommended cut-off values, the optimal treatment and surveillance strategies of both symptomatic and asymptomatic hypoglycemic neonates as well as the treatment targets. Over the past several decades, ΝH has remained an issue of keen debate as it is a preventable cause of brain injury and neurodevelopmental impairment; however, there is no clear definition or consistent treatment policies. Thus, the establishment of specific diagnostic criteria and uniform protocols for the management of this common biochemical disorder is of paramount importance as it will hopefully allow for the early identification of infants at risk, the establishment of efficient preventive measures, the optimal treatment in the first hours of a neonate’s life and, subsequently, the improvement of neonatal outcomes.
