RESUMEN

PURPOSE: SouthSeq is a translational research study that undertook genome sequencing (GS) for infants with symptoms suggestive of a genetic disorder. Recruitment targeted racial/ethnic minorities and rural, medically underserved areas in the Southeastern United States, which are historically underrepresented in genomic medicine research. METHODS: GS and analysis were performed for 367 infants to detect disease-causal variation concurrent with standard of care evaluation and testing. RESULTS: Definitive diagnostic (DD) or likely diagnostic (LD) genetic findings were identified in 30% of infants, and 14% of infants harbored an uncertain result. Only 43% of DD/LD findings were identified via concurrent clinical genetic testing, suggesting that GS testing is better for obtaining early genetic diagnosis. We also identified phenotypes that correlate with the likelihood of receiving a DD/LD finding, such as craniofacial, ophthalmologic, auditory, skin, and hair abnormalities. We did not observe any differences in diagnostic rates between racial/ethnic groups. CONCLUSION: We describe one of the largest-to-date GS cohorts of ill infants, enriched for African American and rural patients. Our results show the utility of GS because it provides early-in-life detection of clinically relevant genetic variations not detected by current clinical genetic testing, particularly for infants exhibiting certain phenotypic features.

RESUMEN

Despite improved outcomes following modifications to the Fontan technique, significant morbidity and mortality persist. We sought to determine if abnormal pre-Fontan catheterization hemodynamic data will predict postoperative prolonged hospital stay (PHLOS) and adverse post-discharge outcomes. This is a retrospective study of patients who underwent the Fontan procedure at Children's Hospital of New Orleans from 2008 to 2018. PHLOS was defined as ≥ 14 and ≥ 21 days to discharge post Fontan. We defined post-discharge adverse outcomes as thromboembolic phenomena requiring anticoagulation therapy, protein-losing enteropathy, plastic bronchitis, transplantation, persistent chylous effusion requiring fenestration creation, or death. Statistical analysis was performed using student t test, Chi-square test, and multivariable logistic regression analysis using IBM SPSS version 22. Ninety-seven patients underwent extracardiac Fontan. Forty-one patients (42.3%) experienced hospitalization ≥ 14 days, 31 patients (32%) experienced hospitalization ≥ 21 days, and 14 patients (14.4%) experienced adverse post-discharge outcome. Elevated end-diastolic pressure (EDP) ≥ 10 mmHg (p = 0.005, OR 4.2, CI 1.5-11.4) was independently associated with ≥ 14 days of hospitalization, while a CI < 4 L/minute/meters2 combined with one abnormal catheterization variable was associated with PHLOS and post-discharge adverse outcomes (p = 0.03, OR 2.8, CI 1.1-7.3 and p = 0.043, OR 6.42, OR 1.1-38.9, respectively). The absence of fenestration was also associated with post-discharge adverse outcomes (p = 0.007, OR 5.8, CI1.6-20.7). Elevated EDP may be associated with PHLOS, while CI < 4 L/minute/meters2 combined with abnormal catheterization hemodynamics may be associated with PHLOS and adverse post-discharge outcomes, while absence of fenestration may be associated with post-discharge adverse events.

RESUMEN

BACKGROUND: It is critical to understand the wide-ranging clinical and non-clinical effects of genome sequencing (GS) for parents in the NICU context. We assessed parents' experiences with GS as a first-line diagnostic tool for infants with suspected genetic conditions in the NICU. METHODS: Parents of newborns (N = 62) suspected of having a genetic condition were recruited across five hospitals in the southeast United States as part of the SouthSeq study. Semi-structured interviews (N = 78) were conducted after parents received their child's sequencing result (positive, negative, or variants of unknown significance). Thematic analysis was performed on all interviews. RESULTS: Key themes included that (1) GS in infancy is important for reproductive decision making, preparing for the child's future care, ending the diagnostic odyssey, and sharing results with care providers; (2) the timing of disclosure was acceptable for most parents, although many reported the NICU environment was overwhelming; and (3) parents deny that receiving GS results during infancy exacerbated parent-infant bonding, and reported variable impact on their feelings of guilt. CONCLUSION: Parents reported that GS during the neonatal period was useful because it provided a "backbone" for their child's care. Parents did not consistently endorse negative impacts like interference with parent-infant bonding.

RESUMEN

BACKGROUND: Several studies have described predictive models to identify trauma patients who require massive transfusion (MT). Early identification of lethal exsanguination may improve survival in this patient population. The purpose of the current study was to validate a simplified score to predict MT at multiple Level I trauma centers. METHODS: All adult trauma patients treated at three Level I trauma centers from July 2006 to June 2007 who (1) were transported directly from the scene, (2) were trauma activations, and (3) received any blood transfusions during admission were included. Assessment of Blood Consumption (ABC) score developed using the same inclusion criteria for patients admitted to a single trauma center (Vanderbilt University Medical Center [VUMC]-1) between July 2005 and June 2006. ABC score calculated by assigning a value (0 or 1) to each of the four parameters: penetrating mechanism, positive focused assessment with sonography for trauma for fluid, arrival blood pressure <90 mm Hg, and arrival pulse >120 bpm. A score of 2 was used as "positive" to predict MT. Area under receiver-operating characteristic curve was calculated to compare the predictive ability of the score at each institution. RESULTS: There were 586 patients in the developmental (VUMC-1), 513 patients at trauma center 1 (VUMC-2), 372 at trauma center 2 (PMH), and 133 at trauma center 3 (Johns Hopkins Hospital). MT rate was similar between centers: 14% to 15%. Sensitivity and specificity for the ABC score predicting MT ranged from 75% to 90% and 67% to 88%, respectively. Correctly classified patients and area under receiver-operating characteristic curve, however, were 84% to 87% and 0.83 to 0.90, respectively. CONCLUSIONS: The ABC score is a valid instrument to predict MT early in the patient's care and across various demographically diverse trauma centers. Future research should focus on this score's ability to prospectively identify patients who will receive MT.
