In addition, they all agree that the use of magnetic resonance imaging should be limited to the evaluation of the extension to pelvic organs in case of placenta percreta. Moreover, American College of Obstetricians and Gynecologists, Royal College of Obstetricians and Gynecologists, International Federation of Gynecology and Obstetrics, and the Society of Obstetricians and Gynecologists of Canada agree that screening for PAS disorders should be based on clinical risk factors along with sonographic findings. Regarding management, they all highlight the importance of a multidisciplinary team approach and recommend delivery by elective cesarean section at a tertiary center with experienced staff and appropriate resources. Routine preoperative ureteric stenting and occlusion of pelvic arteries are universally not recommended. Moreover, hysterectomy following the delivery of the fetus, expectant management with placenta left in situ, and conservative management in case of focal disease and desired fertility are all considered as acceptable treatment options. The reviewed guidelines also suggest some measures for intraoperative and postoperative hemorrhage control and recommend prophylactic administration of antibiotics. Methotrexate after expectant management is unanimously discouraged.

The association between BCAA metabolic changes and nonalcoholic fatty liver disease in PCOS patients has not been fully clarified, which may be related to the lipid accumulation caused by BCAAs. At present, it is believed that hyperandrogenism in patients with PCOS is not related to BCAAs.

In addition, continued investigation into delivery management, breastfeeding recommendations, and congenital abnormalities associated with pregnancies complicated by parvovirus B19 infection is needed.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;This review describes the risks associated with parvovirus B19 infection during pregnancy and the management strategies for fetuses with vertically transmitted infections.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Evidence acquisition: &lt;/strong&gt;Original articles were obtained from literature search in PubMed, Medline, and OVID; pertinent articles were reviewed.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Parvovirus B19 is a viral infection associated with negative pregnancy outcomes. Up to 50% of people of reproductive age are susceptible to the virus. The incidence of B19 in pregnancy is between 0.61% and 1.24%, and, overall, there is 30% risk of vertical transmission when infection is acquired during pregnancy. Although most pregnancies progress without negative outcomes, viral infection of the fetus may result in severe anemia, congestive heart failure, and hydrops fetalis. In addition, vertical transmission carries a 5% to 10% chance of fetal loss. In pregnancies affected by fetal B19 infection, Doppler examination of the middle cerebral artery peak systolic velocity should be initiated to surveil for fetal anemia. In the case of severe fetal anemia, standard fetal therapy involves an intrauterine transfusion of red blood cells with the goal of raising hematocrit levels to approximately 40% to 50% of total blood volume. One transfusion is usually sufficient, although continued surveillance may indicate the need for subsequent transfusions. There are fewer epidemiologic data concerning neonatal risks of congenital parvovirus, although case reports have shown that fetuses with severe anemia in utero may have persistent anemia, thrombocytopenia, and edema in the neonatal period.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions and relevance: &lt;/strong&gt;Parvovirus B19 is a common virus; seropositivity in the geriatric population reportedly reaches 85%.

Concern for parvovirus B19 infection in pregnancy largely surrounds the consequences of vertical transmission of the virus to the fetus. Should vertical transmission occur, the overall risk of fetal loss is between 5% and 10%. Thus, understanding the incidence, risks, and management strategies of pregnancies complicated by parvovirus B19 is essential to optimizing care and outcomes.
