Abstract
Coarctation of the aorta (CoA) is a ductus arteriosus (DA)-dependent form of congenital heart disease (CHD) characterized by narrowing in the region of the aortic isthmus. CoA is a challenging diagnosis to make prenatally and is the critical cardiac lesion most likely to go undetected on the pulse oximetry-based newborn critical CHD screen. When undetected CoA causes obstruction to blood flow, life-threatening cardiovascular collapse may result, with a high burden of morbidity and mortality. Hemodynamic monitoring practices during DA closure (known as an "arch watch") vary across institutions and existing tools are often insensitive to developing arch obstruction. Novel measures of tissue oxygenation and oxygen deprivation may improve sensitivity and specificity for identifying evolving hemodynamic compromise in the newborn with CoA. We explore the benefits and limitations of existing and new tools to monitor the physiological changes of the aorta as the DA closes in infants at risk of CoA.

Abstract
INTRODUCTION In the USA, an estimated 45% of veterans personally own firearms. Firearm access increases the risk of suicide, so suicide prevention efforts in the US Department of Defense (DoD) focus on lethal means safety, including reducing firearm access. Spouse input may enhance effective messaging and intervention delivery of lethal means safety. This study used qualitative methods to explore the perspectives of military spouses or partners on personal firearm storage, including at-home decisions, on-base storage and existing messaging from the DoD. MATERIALS AND METHODS Qualitative data were obtained using 1:1 interviews and focus groups with spouses/partners of US military service members (active duty, Reserve, National Guard, recently separated from the military) and representatives from military support organisations. Sessions focused on personal firearm storage (at home or on military installations) and military messaging around secure firearm storage and firearm suicide prevention. Data were analysed using a team-based, mixed deductive-inductive approach. RESULTS Across 56 participants (August 2022-March 2023), the themes were variability in current home firearm storage and spousal participation in decision-making; uncertainty about firearm storage protocols on military installations; mixed awareness of secure firearm storage messaging from the military; and uncertainty about procedures or protocols for removing firearm access for an at-risk person. CONCLUSION US military spouses are important messengers for firearm safety and suicide prevention, but they are currently underutilised. Tailored prevention campaigns should consider spousal dynamics and incorporate education about installation procedures.

Abstract
OBJECTIVE Acute outcomes after atrioventricular canal defects (AVCD) surgery in the current era are excellent; yet despite surgical advances, ∼15% of patients require future left atrioventricular valve (LAVV) repair. Among patients with AVC who undergo LAVV repair after primary AVC surgery, we sought to characterize the durability of these repairs. Specifically, we aimed to determine predictors for reintervention following an LAVV repair in patients with repaired AVCD, with a focus on postoperative transesophageal echocardiography (TEE). METHODS We reviewed all patients undergoing LAVV repair (after a primary AVCD surgery) at Boston Children's Hospital between 2010 and 2020. Competing risk analysis was performed to evaluate cumulative incidence of LAVV reinterventions. Predictors of LAVV reintervention were evaluated using multivariable Cox regression. RESULTS A total of 137 LAVV repairs following primary AVCD surgery were performed in 113 patients. Median age and weight at LAVV repair were 25 months (interquartile range, 12-76 months) and 11.1 kg (interquartile range, 7.8-19.4 kg). Original anatomy was complete AVCD in 87 (63%), transitional AVCD in 27 (20%), and partial AVCD in 23 (17%) cases. Over a median follow-up of 12 months (interquartile range, 1.3 months-4 years), 47 (34%) of the LAVV repairs required LAVV reintervention. Reinterventions included a total of 27 LAVV re-repairs and 20 LAVV replacements. In multivariable analysis, age at LAVV repair younger than 72 months, partial AVCD anatomy, left ventricle dysfunction, mean LAVV stenosis gradient ≥5 mm Hg, and multiple jets of regurgitation on postoperative LAVV repair TEE were associated with LAVV reintervention. Grade of LAVV regurgitation on postoperative TEE was not an independent risk factor, but reintervention rates were high when residual LAVV stenosis gradient was ≥5 mm Hg and residual mild LAVV regurgitation was present on postoperative TEE (47%) and even higher when residual LAVV stenosis gradient was ≥5 mm Hg and LAVV regurgitation was greater than mild (73%). CONCLUSIONS Reintervention rates remain high for LAVV repairs that occur after primary AVCD surgery, particularly for patients with LAVV stenosis gradient ≥5 mm Hg and mild or greater LAVV regurgitation on postoperative TEE.

Abstract
Globally, health care workers (HCWs) are at a high risk of occupational exposure to needlestick injuries (NSIs). Needlestick injuries not only are associated with an increased risk of infections caused by bloodborne pathogens but are also a primary source of emotional distress and job burnout for HCWs and patients. Insulin injection-related NSIs are common among HCWs working in hospitals in the Asia-Pacific (APAC) region and impose a significant burden. Insulin pen needles have a high risk of transmitting infections (at both the patient-end and cartridge end of the sharp) after use. Recapping a needle after administering an insulin injection poses a major risk to HCWs. Currently, several safety-engineered needle devices (SENDs) are available with active or passive safety mechanisms. Passive insulin safety pen needles with dual-ended protection and automatic recapping capabilities have resulted in a significant drop in accidental punctures to HCWs while administering insulin to patients with diabetes. In this article, we have reviewed the burden and common causes of NSIs with insulin injections among HCWs in the APAC region. We have discussed current approaches to address the issues associated with NSIs and the benefits of introducing SENDs in health care settings, including long-term care facilities, nursing homes, and home care settings where patients may require assisted insulin injections. This review also summarizes key strategies/recommendations to prevent NSIs in HCWs and patients with diabetes in the APAC region.

Abstract
As new variants of SARS-Co-V 2 have emerged over time and Omicron sub-variants have become dominant, the severity of illness from COVID-19 has declined despite greater transmissibility. There are fewer data on how the history, diagnosis, and clinical characteristics of multisystem inflammatory syndrome in children (MIS-C) have changed with evolution in SARS-CoV-2 variants. We conducted a retrospective cohort study of patients hospitalized with MIS-C between April 2020 and July 2022 in a tertiary referral center. Patients were sorted into Alpha, Delta, and Omicron variant cohorts by date of admission and using national and regional data on variant prevalence. Among 108 patients with MIS-C, significantly more patients had a documented history of COVID-19 in the two months before MIS-C during Omicron (74%) than during Alpha (42%) (p = 0.03). Platelet count and absolute lymphocyte count were lowest during Omicron, without significant differences in other laboratory tests. However, markers of clinical severity, including percentage with ICU admission, length of ICU stay, use of inotropes, or left ventricular dysfunction, did not differ across variants. This study is limited by its small, single-center case series design and by classification of patients into era of variant by admission date rather than genomic testing of SARS- CoV-2 samples. Conclusion: Antecedent COVID-19 was more often documented in the Omicron than Alpha or Delta eras, but clinical severity of MIS-C was similar across variant eras. What is Known: • There has been a decrease in incidence of MIS-C in children despite widespread infection with new variants of COVID-19. • Data has varied on if the severity of MIS-C has changed over time across different variant infections. What is New: • MIS-C patients were significantly more likely to report a known prior infection with SARS-CoV-2 during Omicron than during Alpha. • There was no difference in severity of MIS-C between the Alpha, Delta, and Omicron cohorts in our patient population.

Abstract
The degree to which functional abilities explain the negative associations between chronic disease and employment is not well understood. If functional limitations play an important role, then increasing access to accommodations and rehabilitation could facilitate employment among people with chronic illness. If not, other barriers related to living with chronic illness may be at play, calling for other interventions. The goal of this study was to 1) assess how health conditions were associated with employment for adults ages 30-69, and 2) test how much of these illness-employment associations was explained by physical and cognitive/emotional functioning. We fielded the state-of-the-art Work Disability Functional Assessment Battery (WD-FAB) in the nationally-representative RAND American Life Panel (N = 1774) in 2020, stratifying the sample by age and educational attainment. We found that mental health conditions, nervous system/sensory conditions, and cardiovascular conditions were significantly associated with large reductions in the probability of working, at -8, -10, and -19 percentage points (pp) respectively, while there were no significant associations for other conditions. Functional abilities were positively associated with employment to different degrees depending on education. Among those without college degrees, physical functioning (+16 pp) but not cognitive/emotional functioning was significantly associated with working. Among those with college degrees, both physical (+6 pp) and cognitive/emotional (+4 pp) functioning were associated with working. Older workers (ages 51-69) showed a larger association between physical functioning and work with no association between cognitive/emotional functioning and work. Importantly, accounting for functioning reduced the negative associations with employment for mental health and nervous system/sensory conditions but not for cardiovascular conditions. This implies that, for the former conditions, accommodating functional limitations could promote greater employment. However, broader accommodations, such as paid sick leave, increased control over work schedules, and other improvements to working conditions may be necessary to reduce work exits due to cardiovascular conditions.

Abstract
OBJECTIVE To provide evidence-based recommendations and expert guidance for the management of Kawasaki disease (KD), focusing on clinical scenarios more commonly addressed by rheumatologists. METHODS Sixteen clinical questions regarding diagnostic testing, treatment, and management of KD were developed in the Patient/Population, Intervention, Comparison, and Outcomes (PICO) question format. Systematic literature reviews were conducted for each PICO question. We used the Grading of Recommendations, Assessment, Development and Evaluation method to assess the quality of evidence and formulate recommendations. Each recommendation required consensus from at least 70% of the Voting Panel. RESULTS We present 1 good practice statement, 11 recommendations, and 1 ungraded position statement to guide the management of KD and clinical scenarios of suspected KD. These recommendations for KD are focused on situations in which input from rheumatologists may be requested by other managing specialists, such as in cases of treatment-refractory, severe, or complicated KD. The good practice statement affirms that all patients with KD should receive initial treatment with intravenous immunoglobulin (IVIG). In addition, we developed 7 strong and 4 conditional recommendations for the management of KD or suspected KD. Strong recommendations include prompt treatment of incomplete KD, treatment with aspirin, and obtaining an echocardiogram in the setting of unexplained macrophage activation syndrome or shock. Conditional recommendations include use of IVIG with other adjuvant agents for patients with KD and high-risk features of IVIG resistance and/or coronary artery aneurysms. These recommendations endorse minimizing risk to the patient by using established therapy promptly at disease onset and identifying situations in which adjunctive therapy may be warranted. CONCLUSION These recommendations provide guidance regarding diagnostic strategies, use of pharmacologic agents, and use of echocardiography in patients with suspected or confirmed KD.

Abstract
BACKGROUND The Long-terM OUtcomes after the Multisystem Inflammatory Syndrome In Children (MUSIC) study aims to characterize the frequency and time course of acute and long-term cardiac and non-cardiac sequelae in multisystem inflammatory syndrome in children associated with COVID-19 (MIS-C), which are currently poorly understood. METHODS This multicenter observational cohort study will enroll at least 600 patients <21 years old who meet the Centers for Disease Control and Prevention case definition of MIS-C across multiple North American centers over 2 years. The study will collect detailed hospital and follow-up data for up to 5 years, and optional genetic testing. Cardiac imaging at specific time points includes standardized echocardiographic assessment (all participants) and cardiac magnetic resonance imaging (CMR) in those with left ventricular ejection fraction (LVEF) <45% during the acute illness. The primary outcomes are the worst LVEF and the highest coronary artery z-score of the left anterior descending or right coronary artery. Other outcomes include occurrence and course of non-cardiac organ dysfunction, inflammation, and major medical events. Independent adjudication of cases will classify participants as definite, possible, or not MIS-C. Analysis of the outcomes will include descriptive statistics and regression analysis with stratification by definite or possible MIS-C. The MUSIC study will provide phenotypic data to support basic and translational research studies. CONCLUSION The MUSIC study, with the largest cohort of MIS-C patients and the longest follow-up period to date, will make an important contribution to our understanding of the acute cardiac and non-cardiac manifestations of MIS-C and the long-term effects of this public health emergency.

Abstract
OBJECTIVE To characterize viscoelastic testing profiles of children with multisystem inflammatory syndrome in children (MIS-C). METHODS This single-center retrospective review included 30 patients diagnosed with MIS-C from March 1 to September 1, 2020. Thromboelastography (TEG) with platelet mapping was performed in 19 (63%) patients and compared to age- and sex-matched controls prior to cardiac surgery. Relationships between TEG parameters and inflammatory markers were assessed using correlation. RESULTS Patients with MIS-C had abnormal TEG results compared to controls, including decreased kinetic (K) time (1.1 vs. 1.7 minutes, p < .01), increased alpha angle (75.0° vs. 65.7°, p < .01), increased maximum amplitude (70.8 vs. 58.3 mm, p < .01), and decreased lysis in 30 minutes (Ly30) (1.1% vs. 3.7%, p = .03); consistent with increased clot formation rate and strength, and reduced fibrinolysis. TEG maximum amplitude was moderately correlated with erythrocyte sedimentation rate (ESR) (r = 0.60, p = .02), initial platelet count (r = 0.67, p < .01), and peak platelet count (r = 0.51, p = .03). TEG alpha angle was moderately correlated with peak platelet count (r = 0.54, p = .02). Seventeen (57%) patients received aspirin (ASA) and anticoagulation, five (17%) received only ASA, and three (10%) received only anticoagulation. No patients had a symptomatic thrombotic event. Six (20%) patients had a bleeding event, none of which was major. CONCLUSIONS Patients with MIS-C had evidence of hypercoagulability on TEG. Increased ESR and platelets were associated with higher clot strength. Patients were prophylactically treated with ASA or anticoagulation with no symptomatic thrombosis or major bleeding. Further multicenter study is required to characterize the rate of thrombosis and optimal thromboprophylaxis algorithm in this patient population.

Abstract
Evaluate outcomes of single leaflet aortic valve reconstruction using Ozaki sizer and template. Single institute retrospective analysis between August 2015 and August 2019. Thirty-three patients, median age 9.3 years and weight 29.2 kg underwent single leaflet Ozaki repair. Preoperative indications were: AR (n = 17), AS (n = 3) or AS/AR (n = 13). Baseline anatomy was unicuspid (n = 15), bicuspid (n = 9) or tricuspid (n = 9). Two patients had endocarditis. Prior interventions included balloon valvuloplasty (n = 22) and aortic valve repair (n = 9). Pre-op average native annulus diameter was 19.6 mm and peak echo gradient was 36 mm Hg. Autologous pericardium, Photofix and CardioCel bovine pericardium were used in 26, 5, and 2 patients. Non-coronary sinus enlargement was required in 3 and aortic root reduction in 9 patients. Single leaflet reconstruction was done for the right coronary cusp (n = 25), non-coronary cusp in (n = 6) and left coronary cusp (n = 2). Additional procedures were done in 30 patients. Median ICU and hospital LOS were 2.1 and 6.3 days. There were no early re-interventions or conversions to valve replacement and one unrelated mortality.en At discharge, all patients had < moderate AR and/or AS with average peak gradients of 15 mm Hg. The median follow-up was 1.1 year, (IQR 0.7-1.8 years). Freedom from ≥ moderate AR and AS at 2 years was 76% and 86%. One patient required surgical re-intervention for severe AR 1.5 years after surgery for inflammatory infiltrate with calcification and fibrosis. Single-leaflet aortic valve leaflet reconstruction utilizing the Ozaki technique has promising early results and can be considered in patients when there are acceptable native leaflets.

Abstract
BACKGROUND The assessment of real-world effectiveness of immunomodulatory medications for multisystem inflammatory syndrome in children (MIS-C) may guide therapy. METHODS We analyzed surveillance data on inpatients younger than 21 years of age who had MIS-C and were admitted to 1 of 58 U.S. hospitals between March 15 and October 31, 2020. The effectiveness of initial immunomodulatory therapy (day 0, indicating the first day any such therapy for MIS-C was given) with intravenous immune globulin (IVIG) plus glucocorticoids, as compared with IVIG alone, was evaluated with propensity-score matching and inverse probability weighting, with adjustment for baseline MIS-C severity and demographic characteristics. The primary outcome was cardiovascular dysfunction (a composite of left ventricular dysfunction or shock resulting in the use of vasopressors) on or after day 2. Secondary outcomes included the components of the primary outcome, the receipt of adjunctive treatment (glucocorticoids in patients not already receiving glucocorticoids on day 0, a biologic, or a second dose of IVIG) on or after day 1, and persistent or recurrent fever on or after day 2. RESULTS A total of 518 patients with MIS-C (median age, 8.7 years) received at least one immunomodulatory therapy; 75% had been previously healthy, and 9 died. In the propensity-score-matched analysis, initial treatment with IVIG plus glucocorticoids (103 patients) was associated with a lower risk of cardiovascular dysfunction on or after day 2 than IVIG alone (103 patients) (17% vs. 31%; risk ratio, 0.56; 95% confidence interval [CI], 0.34 to 0.94). The risks of the components of the composite outcome were also lower among those who received IVIG plus glucocorticoids: left ventricular dysfunction occurred in 8% and 17% of the patients, respectively (risk ratio, 0.46; 95% CI, 0.19 to 1.15), and shock resulting in vasopressor use in 13% and 24% (risk ratio, 0.54; 95% CI, 0.29 to 1.00). The use of adjunctive therapy was lower among patients who received IVIG plus glucocorticoids than among those who received IVIG alone (34% vs. 70%; risk ratio, 0.49; 95% CI, 0.36 to 0.65), but the risk of fever was unaffected (31% and 40%, respectively; risk ratio, 0.78; 95% CI, 0.53 to 1.13). The inverse-probability-weighted analysis confirmed the results of the propensity-score-matched analysis. CONCLUSIONS Among children and adolescents with MIS-C, initial treatment with IVIG plus glucocorticoids was associated with a lower risk of new or persistent cardiovascular dysfunction than IVIG alone.

Abstract
In the 2017 American Heart Association (AHA) Kawasaki disease (KD) guidelines, risk levels (RLs) for long-term management are defined by both maximal and current coronary artery (CA) dimensions normalized as z-scores. We sought to determine the degree to which current recommended practice differs from past actual practice, highlighting areas for knowledge translation efforts. The International KD Registry (IKDR) included 1651 patients with CA aneurysms (z-score > 2.5) from 1999 to 2016. Patients were classified by AHA RL using maximum CA z-score (RL 3 = small, RL 4 = medium, RL 5 = large/giant) and subcategorized based on decreases over time. Medical management provided was compared to recommendations. Low-dose acetylsalicylic acid (ASA) use ranged from 86 (RL 3.1) to 95% (RL 5.1) for RLs where use was "indicated." Dual antiplatelet therapy (ASA + clopidogrel) use ranged from 16% for RL 5.2 to 9% for RL 5.4. Recommended anticoagulation (warfarin or low molecular weight heparin) use was 65% for RL 5.1, while 12% were on triple therapy (anticoagulation + dual antiplatelet). Optional statin use ranged from 2 to 8% depending on RL. Optional beta-blocker use was 2-25% for RL 5, and 0-5% for RLs 3 and 4 where it is not recommended. Generally, past practice was consistent with the latest AHA guidelines, taking into account the flexible wording of recommendations based on the limited evidence, as well as unmeasured patient-specific factors. In addition to strengthening the overall evidence base, knowledge translation efforts may be needed to address variation in thromboprophylaxis management.

Abstract
Background Coronary artery aneurysms (CAAs) may occur after Kawasaki disease (KD) and lead to important morbidity and mortality. As CAA in patients with KD are rare and heterogeneous lesions, prognostication and risk stratification are difficult. We sought to derive the cumulative risk and associated factors for cardiovascular complications in patients with CAAs after KD. Methods and Results A 34‐institution international registry of 1651 patients with KD who had CAAs (maximum CAA Z score ≥2.5) was used. Time‐to‐event analyses were performed using the Kaplan–Meier method and Cox proportional hazard models for risk factor analysis. In patients with CAA Z scores ≥10, the cumulative incidence of luminal narrowing (>50% of lumen diameter), coronary artery thrombosis, and composite major adverse cardiovascular complications at 10 years was 20±3%, 18±2%, and 14±2%, respectively. No complications were observed in patients with a CAA Z score <10. Higher CAA Z score and a greater number of coronary artery branches affected were associated with increased risk of all types of complications. At 10 years, normalization of luminal diameter was noted in 99±4% of patients with small (2.5≤Z<5.0), 92±1% with medium (5.0≤Z<10), and 57±3% with large CAAs (Z≥10). CAAs in the left anterior descending and circumflex coronary artery branches were more likely to normalize. Risk factor analysis of coronary artery branch level outcomes was performed with a total of 893 affected branches with Z score ≥10 in 440 patients. In multivariable regression models, hazards of luminal narrowing and thrombosis were higher for patients with CAAs of the right coronary artery and left anterior descending branches, those with CAAs that had complex architecture (other than isolated aneurysms), and those with CAAs with Z scores ≥20. Conclusions For patients with CAA after KD, medium‐term risk of complications is confined to those with maximum CAA Z scores ≥10. Further risk stratification and close follow‐up, including advanced imaging, in patients with large CAAs is warranted.

Abstract
Fetuses with congenital heart disease (CHD) have third trimester alterations in cortical development on brain magnetic resonance imaging (MRI). However, the intersulcal relationships contributing to global sulcal pattern remain unknown. This study applied a novel method for examining the geometric and topological relationships between sulci to fetal brain MRIs from 21-30 gestational weeks in CHD fetuses (n = 19) and typically developing (TD) fetuses (n = 17). Sulcal pattern similarity index (SI) to template fetal brain MRIs was determined for the position, area, and depth for corresponding sulcal basins and intersulcal relationships for each subject. CHD fetuses demonstrated altered global sulcal patterns in the left hemisphere compared with TD fetuses (TD [SI, mean ± SD]: 0.822 ± 0.023, CHD: 0.795 ± 0.030, P = 0.002). These differences were present in the earliest emerging sulci and were driven by differences in the position of corresponding sulcal basins (TD: 0.897 ± 0.024, CHD: 0.878 ± 0.019, P = 0.006) and intersulcal relationships (TD: 0.876 ± 0.031, CHD: 0.857 ± 0.018, P = 0.033). No differences in cortical gyrification index, mean curvature, or surface area were present. These data suggest our methods may be more sensitive than traditional measures for evaluating cortical developmental alterations early in gestation.

Abstract
Anomalous origin of a coronary artery from the pulmonary artery (PA) is a rare congenital anomaly with the most common pattern being an anomalous left coronary artery (LCA) from the pulmonary artery (ALCAPA). A very rare pattern is the anomalous origin of a single coronary artery from the pulmonary artery (ASCAPA) wherein the single coronary ostium supplies both the right and left coronary systems with profound myocardial ischemia developing once PA pressures begin to fall after birth. Previous reports of this anomaly have all been based on post-mortem findings or pre-mortem angiographic diagnosis [1-3]. Notably, these children often present in extremis due to cardiogenic shock. Institution of veno-arterial extracorporeal life support can be catastrophic as it would lead to myocardial ischemia due to PA decompression. We present here the first echocardiographic-only diagnosis of ASCAPA in a 2-month-old child with the use of bubble contrast echocardiography to help confirm the diagnosis. The patient was resuscitated from a cardiac arrest on arrival with subsequent echocardiographic-only diagnosis. Surgical repair was undertaken with administration of cardioplegia into the pulmonary root with snaring of the branch PAs, and re-implantation of the single coronary to the aorta. At 3-month follow-up, he is thriving clinically with echocardiogram showing improving-though still somewhat depressed-left ventricular function.

Abstract
Interrupted right aortic arch is a rare congenital cardiovascular anomaly typically associated with other forms of congenital heart disease. We report two cases of interrupted right aortic arch associated with isolated left pulmonary artery and bilateral ductus arteriosus in the first case and with truncus arteriosus in the second case. Computed tomography was complementary to echocardiography in delineating the anatomic details in both cases, informing surgical repair with reconstruction of a left aortic arch in the first case and right arch in the second case.

Abstract
BACKGROUND Preclinical studies suggest that bb2121, a chimeric antigen receptor (CAR) T-cell therapy that targets B-cell maturation antigen (BCMA), has potential for the treatment of multiple myeloma. METHODS In this phase 1 study involving patients with relapsed or refractory multiple myeloma, we administered bb2121 as a single infusion at doses of 50×106, 150×106, 450×106, or 800×106 CAR-positive (CAR+) T cells in the dose-escalation phase and 150×106 to 450×106 CAR+ T cells in the expansion phase. Patients had received at least three previous lines of therapy, including a proteasome inhibitor and an immunomodulatory agent, or were refractory to both drug classes. The primary end point was safety. RESULTS Results for the first 33 consecutive patients who received a bb2121 infusion are reported. The data-cutoff date was 6.2 months after the last infusion date. Hematologic toxic effects were the most common events of grade 3 or higher, including neutropenia (in 85% of the patients), leukopenia (in 58%), anemia (in 45%), and thrombocytopenia (in 45%). A total of 25 patients (76%) had cytokine release syndrome, which was of grade 1 or 2 in 23 patients (70%) and grade 3 in 2 patients (6%). Neurologic toxic effects occurred in 14 patients (42%) and were of grade 1 or 2 in 13 patients (39%). One patient (3%) had a reversible grade 4 neurologic toxic effect. The objective response rate was 85%, including 15 patients (45%) with complete responses. Six of the 15 patients who had a complete response have had a relapse. The median progression-free survival was 11.8 months (95% confidence interval, 6.2 to 17.8). All 16 patients who had a response (partial response or better) and who could be evaluated for minimal residual disease (MRD) had MRD-negative status (≤10-4 nucleated cells). CAR T-cell expansion was associated with responses, and CAR T cells persisted up to 1 year after the infusion. CONCLUSIONS We report the initial toxicity profile of a BCMA-directed cellular immunotherapy for patients with relapsed or refractory multiple myeloma. Antitumor activity was documented.

Abstract
Introduction: mTBI is associated with anterior pituitary hormone dysfunction. The potential long-term effect of this injury on pituitary function in Veterans is not clear. Methods: We present an interim report of our 4-year longitudinal prospective pilot study of pituitary function in Veterans diagnosed with mTBI. Of the 34 mTBI Veterans enrolled, we have tested 28 of them (4 female, 24 male; mean±SD age and BMI, 31.1±7.0 years and 30.2±6.2, respectively) for baseline pituitary hormone levels and cortisol response to ACTH. In 22 subjects growth hormone response to glucagon stimulation (GST) was tested at baseline. The same baseline data were obtained for 15 age-, sex-, deployment- and BMI-matched control subjects without mTBI (2 female,13 male; mean±SD age and BMI 33.9±6.8 years and 32.7±7.2, respectively). Follow-up testing has been done for 18 mTBI subjects in Year 1, 13 subjects in Year 2, 8 subjects in Year 3 and 3 subjects in Year 4. GH cutoffs of <1ng/mL for patients with a BMI≥25, and ≤ 3 ng/mL for a BMI < 25 were used for the diagnosis of GHD. Results: GHD was present in 9% (2/22) at baseline, 22% (4/18) at Year 1, 8% (1/13) at Year 2, 22% (2/9) at Year 3, and 0% (0/3) at Year 4. GHD did not occur in the same subject in subsequent years, and it appeared to recover within a year. The peak GST GH level for all subjects at each year trended downward from baseline to Years 1, 2, 3, and 4: (ng/mL, mean±SD) 7.6±7.7; 7.5±13.0; 3.5±3.3; 4.4±4.3; 1.9±0.9, respectively. Secondary hypogonadism occurred in 11%, 6%, 8% of subjects at baseline, Year 1 and Year 2, respectively; none has been found in Years 3 and 4. There are no subjects identified with hypothyroidism or overt adrenal insufficiency at baseline or over 4 years. Unexpectedly, GHD was detected in 27% (4/15) of control subjects. The mean±SD BMI of 39.4±7.8 for these subjects was higher than the BMI values for GH sufficient (GHS) control subjects (30.2±5.2), mTBI patients with GHD (29.6±4.6) and GHS (30.9±6.2). Secondary hypogonadism was present in 14%, and there were no cases of hypothyroidism or adrenal insufficiency. Conclusions: GHD occurs in patients with mTBI at up to 3 years of observation using the stricter GH cutoff criterion with a BMI ≥25. Because each patient with GHD in a particular year was unique, the cumulative occurrence of GHD thus far is 41% (9/22) over 4 years. The highest prevalence was in Year 2. Each subject appeared to recover from GHD in one year. Attrition of subjects has decreased the later year numbers; a more complete review will be possible when the remaining subject testing is completed. The detection of GHD in the non-mTBI control group suggests there may be additional factors in deployment itself that can put military personnel at risk. BMI as a confounding factor with the GST or any GH testing cannot be excluded. Identification of GHD and hypogonadism in Veterans with mTBI will provide treatment opportunities to enhance their recovery.

Abstract
Fetal cardiac intervention (FCI) offers the potential to alter in utero anatomy and physiology. For aortic stenosis with evolving hypoplastic left heart syndrome and pulmonary atresia with intact ventricular septum with evolving hypoplastic right heart syndrome, FCI may result in maintenance of a biventricular circulation, thus avoiding single-ventricle palliation and its attendant complications. In the case of hypoplastic left heart syndrome with intact atrial septum, FCI may ameliorate in utero pathophysiology and portend a more favorable postnatal prognosis. In all cases, a detailed fetal echocardiographic assessment to identify the appropriate FCI candidate is essential. This article reviews the three aforementioned lesions for which FCI can be considered. The pathophysiology and rationale for intervention, echocardiographic assessment, patient selection criteria, and outcomes for each lesion will be reviewed. A primary focus will be the echocardiographic evaluation of each lesion.

Abstract
Interrupted aortic arch (IAA) is a rare form of critical neonatal heart disease in which there is lack of continuity between the ascending aorta and the descending thoracic aorta. In the absence of prenatal diagnosis, patients with IAA present in shock when the patent ductus arteriosus closes. Diagnosis can generally be made by echocardiography, and initiation of prostaglandin E1 infusion allows for adequate lower body perfusion prior to surgical repair. Full neonatal repair can be achieved with good outcomes in most cases. However, there is often underdevelopment of the left ventricular outflow tract and risk for later surgical re-intervention. Many patients with IAA, particularly those with type B, have DiGeorge syndrome, which has important development implications.

Abstract
The epidemic of Zika virus (ZIKV) has resulted in a surge of newborns with microcephaly and brain abnormalities. In this report, we describe the first case, to our knowledge, of congenital Zika syndrome with concomitant critical congenital heart disease. The mother had a confirmed ZIKV infection in the first trimester of pregnancy. Fetal ultrasonography at 31 weeks of gestation revealed cerebral cortical calcifications and hypoplastic left heart syndrome. The severity of brain involvement was assessed by postnatal magnetic resonance imaging and echocardiogram, and palliative surgery was performed. The ethical dimensions of this infant's clinical management are discussed. ZIKV is known to affect neural progenitor cells, but whether it could have a tropism for other tissues remains unclear.
