Is bigger better? A comparison of growth restriction rates using the crown-rump length derived due date from the smaller versus larger twin.

BACKGROUND: Although the smaller twin's crown-rump length is most accurate in establishing the estimated due date in dichorionic gestations, societal guidelines favor the use of the larger twin measurements based on concern for missing a diagnosis of fetal growth restriction. OBJECTIVE: This study aimed to compare the accuracy of the diagnosis of early- and late-onset fetal growth restriction in dichorionic twin gestations conceived by assisted reproductive technology using the estimated due date as established by the crown-rump length of the smaller vs larger twin. STUDY DESIGN: This was a 10-year retrospective cohort study of nonanomalous, dichorionic gestations conceived with assisted reproductive technology at 2 institutions. The incidence of early-onset (<32 weeks of gestation) and late-onset (≥32 weeks of gestation) growth restriction derived from the Hadlock formula using the smaller and larger crown-rump length estimated due date was compared with the true estimated due date by assisted reproductive technology. Statistical significance was determined using the Fisher exact test. The incidence of missed fetal growth restriction cases, false-positive rate, and error were calculated along with the relative risk for a missed diagnosis using the smaller crown-rump length. RESULTS: A total of 176 subjects were screened: 81 had a fetal growth ultrasound at 24 to <32 weeks of gestation, and 58 had a fetal growth ultrasound at ≥32 weeks of gestation. There was a significant difference in the incidence of fetal growth restriction using the 3 dating strategies in both gestational age ranges (P<.001) with the smaller crown-rump length estimated due date more closely approximating the true rate. Before 32 weeks of gestation, the smaller crown-rump length estimated due date missed 2.5% of fetal growth restriction cases, whereas the larger crown-rump length estimated due date missed 0.6% of fetal growth restriction cases, with false-positive and error rates of 1.2% and 3.7% and 5.5% and 6.2%, respectively. After 32 weeks of gestation, the smaller crown-rump length estimated due date missed 1.8% of cases, whereas the larger crown-rump length estimated due date missed 0% of cases, with false-positive and error rates of 2.6% and 4.4% and 5.3% and 5.3%, respectively. The relative risk for a missed diagnosis of fetal growth restriction using the smaller crown-rump length estimated due date was 1.77 for early-onset growth restriction and 1.22 for late-onset growth restriction. CONCLUSION: Using the estimated due date derived from the smaller twin led to a more accurate detection of fetal growth restriction at a cost of a higher missed diagnosis rate.

A Randomized Controlled Trial on the Effect of Standardized Video Education on Prenatal Genetic Testing Choices: Uptake of Genetic Testing.

OBJECTIVE: This study aimed to assess the use of a standardized prenatal genetic testing educational video and its effects on patient uptake of prenatal testing, patient knowledge, decisional conflict, and decisional regret. STUDY DESIGN: This was an Institutional Review Board-approved randomized controlled trial. Patients were randomized to intervention (standardized video education) or control (no video education). The video education group viewed a 5-minute educational video on genetic testing options, and the control group did not review the video. Both groups answered validated questionnaires to assess maternal knowledge (Maternal Serum Screening Knowledge Questionnaire [MSSK]), conflict (Decisional Conflict Scale [DCS]), and regret (Decisional Regret Scale [DRS]). The primary outcome was genetic testing uptake; secondary outcomes were knowledge-based test score, and level of decisional conflict and regret. RESULTS: We enrolled 210 patients between 2016 and 2020, with 208 patients randomized, 103 patients in the video education group and 105 patients in the control group. Four patients were excluded from the video education group for missing data. Video education was associated with a 39% lower chance of prenatal testing compared with patients who did not receive video education, (odds ratio 0.39, 95% confidence interval 0.16-0.92). Patients in the video education group had higher mean MSSKQ scores by 2.9 points (8.5 vs. 5.7, p < 0.001), lower Decisional Conflict Scores by 7.3 points (31.5 vs. 38.8, p < 0.001), lower Decisional Regret Scores by 5.4 points (23.8 vs. 29.2, p < 0.001). CONCLUSION: We found that video education on prenatal genetic testing improved patients' knowledge, decreased testing and decisional conflict and regret regarding testing. This may indicate improved understanding of testing options and more informed decisions that align with their personal values and beliefs. This standardized video can be easily implemented in clinical practice to increase patient understanding and support decisions that align with patient's values. KEY POINTS: · A standardized educational video improves patient knowledge about prenatal testing options in pregnancy.. · Video education decreases testing and decisional conflict and decisional regret in pregnancy.. · A standardized educational video may be used in the clinical setting to educate patients on testing options and help them make informed decisions about testing..

Comparing Compensation of U.S. Military Physicians and Civilian Physicians in Residency Training and Beyond.

Introduction  Resident physicians have a professional degree but are compensated less than other recently graduated professionals such as lawyers or nurse practitioners. The U.S. Military Healthcare System differs from the civilian setting in that physicians' salaries are based primarily on military rank. We compared military and civilian physician salaries across various specialties to determine if the increased military pay during residency compensates for military attending physicians' lower income as compared to their civilian counterparts. Methods This cross-sectional study compares military and civilian pay for resident and attending physicians in the fields of Obstetrics & Gynecology (OB/GYN), Family Medicine, and General Surgery. Military pay was obtained from 2018 Defense Finance and Accounting Service (DFAS) data. Civilian salaries were obtained from the Medscape 2018 Residents Salary & Debt Report, Medical Group Management Association (MGMA) 2018 Provider Compensation Report, and 2017-2018 Association of American Medical Colleges (AAMC) Faculty Salary Report. Results Military resident physicians earned 53% more than civilian residents while military attending physicians earned 32%-58% less (after taxes) than their civilian counterparts, varying by specialty. Military attending physicians' negative pay differential occurred in both academic and non-academic practice environments through MGMA data. Discussion The positive pay differential in military residency does not compensate for the negative pay differential of military attending physicians face as compared to their civilian counterparts. This negative pay differential persisted when comparing post-tax pay. Some military service benefits, such as decreased educational debt, are challenging to quantify and vary considerably between individuals. As the military seeks to reshape its healthcare force, military and civilian compensation differences should be considered.

Establishing the Most Accurate Due Date in Dichorionic Twin Gestations by First and Second Trimester Ultrasound.

OBJECTIVE: To determine the optimal sonographic dating of dichorionic gestations. MATERIALS AND METHODS: We reviewed dichorionic pregnancies conceived with assisted reproductive technologies (ART) at 2 institutions between 2006-2016, excluding fetuses with major anomalies. Gestational age was calculated with smaller, larger, and mean of the crown-rump lengths (CRL) and biometry midgestation and compared to the ART age. The mean and mean absolute deviation of the observed gestational age from the ART age was calculated to assess accuracy, precision, and presence of bias. The incidence of small for gestational age using the smaller and larger CRLs was compared to the ART age via McNemar's test. RESULTS: Based on 140 ultrasounds, the CRL from the smaller twin best approximates the true gestational age with least bias compared to the larger twin or average (mean absolute deviation: 2.8, mean deviation: -0.1 [95% CI: -0.4, 0.2] versus 2.7, -0.9 [-1.1, -0.6] and 2.9, -1.5 [-1.8, -1.3], in days, respectively). Based on 165 ultrasounds, biometry from the smaller fetus is least accurate compared to the larger or mean (11.8, 2.5 [1.5, 3.6] versus 11.7, 0.8 [-0.3, 1.8] and 11.9, -1.0 [-2.0, 0.04], respectively). The incidence of small for gestational age neonates did not differ from the true rate using either the CRL from the larger or smaller twin (p > .05). CONCLUSION: In ART dichorionic gestations, ultrasound of the smaller fetus is most accurate in establishing gestational age in the first trimester but least accurate in the second, though all methods performed well with little clinical difference.

Identifying Prevalence and Risk Factors for Mild Cognitive Impairment in Adults Presenting for Urological Evaluation.

OBJECTIVE: To examine mild cognitive impairment (MCI) in a young and older adult urology population, and which external factors were associated with diminished cognitive status at baseline. METHODS: We enrolled patients >18 years of age presenting to a large, urban tertiary care center for a wide variety of urologic complaints. Cognitive status was determined by the Montreal Cognitive Assessment (MoCA) screening test. A score of 26-30 on the MoCA is considered cognitively intact, whereas <26 indicates MCI. Patient charts were retrospectively reviewed; a backwards-stepwise logistic regression was constructed to compare MCI with potential risk factors. RESULTS: One hundred ninety-seven patients were included. There were 10/33 (30%) patients aged 18-40 who had MCI. Moreover, 32/68 (47%) patients aged 41-64 had MCI. Of older adults age 65+, MCI was seen in 65/96 (68%) patients. Factors associated with MCI in age group 41-64 included opioid use. Patients with stone disease were less likely to demonstrate MCI, when compared to other general categories of urologic chief complaints. For patients in age group 65+, associations with MCI included a cancer-related chief complaint, increased age, depressive symptoms, and less education. There were no significant associations with MCI in age group 18-40. CONCLUSION: These results demonstrate a significant prevalence of MCI in an adult urology population and factors that may be associated with its prevalence. We believe that this study lays the groundwork for urology providers to be able to identify patients who may have MCI at baseline.
