Motivation: how to create a cohort of engaged, energized, and happy radiology trainees.

Burnout among physicians continues to be a "hot topic" as medical culture struggles to adapt to the changing marketplace, where clinical demands are ever increasing but healthcare systems are pivoting to prefer value and cost-savings. To date, many attempts to understand and battle burnout center around the individual physician, rather than the system, limiting the medical community's ability to counter it successfully. The training environment is a common nidus for burnout. By promoting an understanding of motivation, happiness, and engagement in the workplace, we suggest several changes that training programs can make to minimize burnout and promote resident wellness. Creating a culture of support, promoting a positive work environment, building a cohesive team, and encouraging wellness both inside and outside the workplace stands to create engaged, happy, and motivated trainees who will hopefully continue to promote those strategies as they advance their careers.

Vasa previa: diagnosis and management.

BACKGROUND: Vasa previa is a rare condition that is associated with a high rate of fetal or neonatal death when not diagnosed antenatally. The majority of available studies are either small, do not include antepartum data, limited to single institutions, or are biased by inclusion of patients from registries and online vasa previa support groups. OBJECTIVE: The purpose of this study was to investigate the diagnostic and management strategies for this potentially catastrophic entity and to describe further maternal and placental risk factors that may aid in the establishment of a screening protocol for vasa previa. STUDY DESIGN: This was a retrospective multicenter descriptive study that included all pregnancies that were complicated by vasa previa that delivered between January 1, 2000, and December 31, 2012. Nine maternal fetal medicine practices and the hospitals in which they practice participated in data collection of diagnosis, treatment, and maternal-neonatal outcomes. RESULTS: Sixty-eight pregnancies were identified that included the diagnosis of vasa previa or "possible vasa previa" either in the ultrasound record or in the hospital record at the time of delivery. Four cases (5.8%) appeared to resolve on repeat ultrasound examination. Fifteen of the 64 cases that were suspected of having vasa previa could not be verified or were not documented at delivery. Of the remaining 49 cases, where vasa previa was documented, 47 cases (96%) were diagnosed by ultrasound scanning antenatally. Known risk factors for vasa previa were present in 41 of 47 cases (87%). Of the 49 cases, 41 were delivered by planned cesarean delivery at a mean gestational age of 34.7 weeks, and 8 cases required emergent cesarean delivery at a mean gestational age of 34.6 weeks (range, 32.4-36.0 weeks gestation). Seven of these emergent cesarean deliveries had been diagnosed previously; 1 case had not. All of the emergent cesarean deliveries were for vaginal bleeding; 1 case was also for a concerning fetal heart rate, but only 1 of the known cases had a documented ruptured fetal vessel. None of these cases were found to have cervical shortening before the onset of bleeding. One of the undiagnosed cases resulted in a ruptured fetal vessel and a baby with no heart beat at birth who survived but had periventricular leukomalacia at 1 month of age with mild white-matter atrophy. Of the remaining neonates in this group, there were no deaths and no major complications beyond mild respiratory distress syndrome in 9 cases. There were no other major neonatal complications, which included no cases of periventricular leukomalacia, neonatal sepsis, necrotizing enterocolitis, or any grade of intraventricular hemorrhage in the confirmed cases of vasa previa. CONCLUSION: This study confirms most current recommendations that include risk-based ultrasound screening, early hospitalization at 30-34 weeks gestation, antenatal corticosteroids at 30-32 weeks gestation, and elective delivery at 33-34 weeks gestation. Thus, with these recommendations for current identification and management of vasa previa in this series of geographically diverse mostly private practice maternal fetal medicine practices, we have confirmed recent reports that show a dramatic improvement in neonatal survival and complications compared with earlier reports.

Evidence for the clinical management of chorioamnionitis.

Acute chorioamnionitis or intra-amniotic infection is defined by maternal fever in association with at least one additional clinical criterion including maternal or fetal tachycardia, maternal leukocytosis, uterine tenderness, or foul amniotic fluid odor. In clinically uncertain cases, the diagnosis can be augmented by routine laboratory studies (e.g. white blood cell count and differential count and acute phase reactants) and assays done on amniotic fluid. In general, the clinical management of chorioamnionitis is based on observational or cohort studies; only a few randomized controlled trials have been done. Prompt administration of antibiotics and delivery decrease maternal and neonatal morbidity. The most commonly used antibiotic regimen is ampicillin and gentamicin. Recent evidence supports daily rather than three-times-daily dosing of gentamicin for greater efficacy and decreased fetal toxicity. There is no evidence demonstrating harm with the administration of corticosteroids (to promote fetal lung maturity) in women with acute chorioamnionitis. Cesarean delivery should be reserved for standard obstetric indications.

Facets of impulsivity in the relationship between antisocial personality and abstinence.

Most individuals who enter drug treatment programs are unable to maintain long-term abstinence. This problem is especially relevant for those presenting with Antisocial Personality Disorder (ASPD). In examining potential mechanisms underlying the relationship between ASPD and abstinence, one factor that may be especially useful is the personality variable of impulsivity. Thus, the current study examined ASPD status in relation to longest abstinence attempt among 117 substance use treatment-seeking individuals, considering the mediating role of five facets of impulsivity: urgency, perseverance, premeditation, control, and delay discounting. Results indicated that individuals with ASPD evidenced shorter previous abstinence attempts and lower levels of perseverance and control than those without ASPD. Further, lower levels of control were associated with shorter abstinence attempts. Finally, control mediated the relationship between ASPD and longest quit attempt. These results suggest the potential value of multiple facets of impulsivity in efforts to understand relapse and subsequent treatment development efforts.

Risk factors for preterm delivery with placenta previa.

AIMS: To identify factors associated with preterm delivery in cases of sonographically identified placenta previa. METHODS: Pregnancies with sonographic evidence of placenta previa at ≥ 28 weeks were identified. Demographic information, antepartum course, and delivery information were extracted from electronic medical records. Statistical analysis was performed with Fisher's exact test, Mann-Whitney U, Spearman's ρ (correlation), and logistic regression. Continuous data are presented as median (interquartile range). RESULTS: Of 113 singleton pregnancies with placenta previa, 54 (48%) delivered at term and 59 (52%) delivered preterm. Fifty-one (45%) experienced antepartum bleeding at a median gestational age of 31 weeks (29-33 weeks) with a median interval of 20 days (11-33 days) between first bleeding episode and delivery. Women with antepartum bleeding were more likely to be delivered for hemorrhage (36 of 51 vs. 8 of 62, P<0.001) and delivered emergently (40 of 51 vs. 14 of 62, P<0.001). Antepartum bleeding before 34 weeks had a positive predictive value of 88% for preterm birth and 83% for emergent delivery. CONCLUSION: In pregnancies with placenta previa, antepartum bleeding is a strong predictor of preterm delivery.

The utility of fetal echocardiography after an unremarkable anatomy scan.

OBJECTIVE: To estimate whether fetal echocardiography detects major cardiac anomalies after normal anatomy ultrasound scan in patients at increased risk for having a fetus with congenital heart disease. METHODS: A computerized database was used to identify patients who underwent fetal echocardiography at the New York University Division of Pediatric Cardiology after anatomy ultrasound scan at the New York University Obstetrics and Gynecology Ultrasound Unit. Only patients with normal anatomy ultrasound scan results were included in the primary analysis. Patients were excluded if they had suspicious cardiac views on anatomy ultrasound scan or extracardiac anomalies. Major cardiac anomalies were defined as those judged by a blinded pediatric cardiologist as likely to require medical or surgical intervention in the first 6 months of life. RESULTS: Of 1,034 patients in the pediatric cardiology database, 536 patients underwent anatomy ultrasound scan at the New York University Obstetrics and Gynecology Department. Eighty patients in the case group were excluded for suspicious or inadequate cardiac views and 139 were excluded for extracardiac ultrasound findings. Of the remaining 317 patients with normal obstetric ultrasound scan results, none had a major cardiac malformation diagnosed on fetal echocardiography. CONCLUSION: In a tertiary care center with operators performing a high volume of ultrasound screenings, fetal echocardiography after normal anatomy ultrasound scan may be of limited benefit. LEVEL OF EVIDENCE: III.

Risk factors for emergent preterm delivery in women with placenta previa and ultrasound findings suspicious for placenta accreta.

AIM: To identify factors associated with emergent preterm delivery in women with placenta previa and suspected accreta. METHODS: Pregnancies with placenta previa and ultrasound findings suspicious for accreta were identified. Demographic information and obstetric and neonatal outcomes were obtained from electronic medical records. Mann-Whitney U, Fisher's exact test, and Kaplan-Meier analysis were used. Continuous data are expressed as median (interquartile range). RESULTS: Twenty-one patients with placenta previa and suspicion for accreta delivered at a median of 34 weeks [32-37]. Fourteen bled prior to delivery, 10 at <32 weeks. Fifty-seven percentage of deliveries were planned at a median gestational age of 36.5 weeks [34-37] vs. 32 weeks [29.5-32.5] for emergent deliveries (P<0.001). Emergent delivery was associated with transfusion of a median of nine units packed red blood cells (PRBCs) [4-16] compared to 4.5 units [1-7] with planned delivery (P=0.05). CONCLUSION: Planned late perterm delivery is reasonable and likely women with placenta previa and ultrasound findings suspicious for placenta accreta who do not experience antepartum bleeding. Those women with multiple episodes of antepartum bleeding or bleeding prior to 32 weeks gestation are at increased risk of emergent preterm delivery.

Parvovirus-mediated fetal cardiomyopathy with atrioventricular nodal disease.

Acute parvovirus B19 infection (API) in pregnancy has been associated with fetal anemia and hydrops fetalis. Direct myocardial damage from API in a fetus and an infant has been described. This report presents a case of fetal second-degree heart block and cardiomyopathy secondary to API. A 19-year-old G4P1112 (gravida 4 para 2 with 1 term delivery, 1 preterm delivery, 1 termination, and 2 living children) was referred at 20 weeks gestation for fetal bradycardia. A 2:1 atrioventricular block was identified by fetal echocardiography at 23 weeks. Hydrops developed at 25 weeks. Amniocentesis and percutaneous umbilical blood sampling demonstrated API. At 31 weeks, the patient presented with preterm labor and delivered a viable female infant, who died of poor cardiac function and arrhythmia on the first day of life. In addition to fetal anemia and hydrops fetalis, API in pregnancy may cause direct fetal myocardial damage and conduction system disease.

Maternal and neonatal outcomes after delayed-interval delivery of multifetal pregnancies.

The objective of this study is to evaluate neonatal and maternal outcomes of multiple gestations undergoing delayed-interval delivery at a single institution. A 10-year retrospective review of medical records of patients followed by a Maternal-Fetal Medicine practice in a university-based setting was performed. Patients met criteria for inclusion if a single fetus was delivered spontaneously between 16 and 28 weeks of gestation and a planned attempt was made to prolong the gestation for the remaining fetus(es). Nineteen pregnancies met criteria for inclusion. The median gestational age at delivery of the first fetus was 20 (2)/(7) weeks and the last fetus was 25 (1)/(7) weeks. The median latency was 16 days (range 0 to 152 days). Three patients (15.8%) delivered within 24 hours. There was a 15.8% survival rate for the firstborn fetus and a 53.8% survival rate for all retained fetuses (p = 0.01). There was a 31.6% incidence of serious maternal morbidity related to the procedure. One patient required a postpartum hysterectomy due to massive hemorrhage and uterine atony. Delayed-interval delivery is associated with a higher neonatal survival rate when retained fetuses are compared with firstborn fetuses. However, the procedure is associated with a significant risk of serious maternal morbidity.

Severe uropathy and normal amniotic fluid volume in a male fetus: sonographic surveillance leading to the diagnosis of megacystis-microcolon-intestinal hypoperistalsis syndrome.

The widespread use of sonography as a screening tool for fetal anomalies has facilitated prenatal detection of several fetal conditions characterized by urinary tract dilatation. These conditions are more common in male fetuses and are generally a result of an anatomic defect causing obstruction along the urinary tract system. Although the prognosis of these conditions largely depends on the specific anomaly, several poor prognostic factors have been described. These factors include detection at an early gestational age, bilateral marked dilatation, a persistently obstructed bladder, oligohydramnios causing pulmonary hypoplasia, and the presence of associated fetal or chromosomal anomalies. We report a case in which a male fetus at 14 weeks' gestation had a diagnosis of rapidly progressing bilateral hydronephrosis, massive bladder dilatation, hydroureter, and a surprisingly normal amniotic fluid volume. Serial sonographic surveillance assisted us in obtaining the correct diagnosis, which was important for adequately consulting the patient regarding the fetal prognosis in the affected index pregnancy as well as the likelihood of recurrence in future gestations.
