OVARIO phase II trial of combination niraparib plus bevacizumab maintenance therapy in advanced ovarian cancer following first-line platinum-based chemotherapy with bevacizumab.

OBJECTIVE: To assess safety and efficacy of niraparib + bevacizumab as a first-line maintenance therapy for patients with newly diagnosed advanced ovarian cancer. METHODS: This multicenter, phase II, single-arm, open-label study enrolled adult patients with stage IIIB to IV ovarian, fallopian tube, or primary peritoneal cancer (NCT03326193). Patients were required to have an attempt at debulking surgery and have a complete response, partial response, or no evidence of disease following first-line, platinum-based chemotherapy with ≥3 cycles of bevacizumab. The primary endpoint was the progression-free survival (PFS) rate at 18 months. Secondary endpoints included PFS, overall survival, and safety. RESULTS: Among the 105 evaluable patients, the PFS rate at 18 months was 62% (95% CI 52-71%) in the overall population and 76% (95% CI 61-87) in the homologous recombination deficient (HRd), 47% (95% CI 31-64%) in the HR proficient (HRp), and 56% (95% CI 31-79%) in the HR not determined (HRnd) subgroups (December 24, 2020, cutoff). After a median follow-up time of 28.7 months (IQR, 23.9-32.5 months), median PFS was 19.6 months (95% CI 16.5-25.1) in the overall population (N = 105) and 28.3 months (95% CI 19.9-NE), 14.2 months (95% CI 8.6-16.8), and 12.1 months (95% CI 8.0-NE) in the HRd, HRp, and HRnd subgroups, respectively (June 16, 2021, cutoff). The most common any-grade treatment-related adverse events (related to niraparib and/or bevacizumab) were thrombocytopenia (74/105), fatigue (60/105), and anemia (55/105; December 24, 2020, cutoff). CONCLUSION: Niraparib + bevacizumab first-line maintenance therapy displayed promising PFS results. Safety was consistent with the known safety profiles of niraparib and bevacizumab as monotherapy.

Factors Associated with Inability to Discharge After Stage 1 Palliation for Single Ventricle Heart Disease: An Analysis of the National Pediatric Cardiology Quality Improvement Collaborative Database.

Patient-level characteristics associated with survival for single ventricle heart disease following initial staged palliation have been described. However, the impact of peri-operative events on hospital discharge has not been examined. To characterize patient-level characteristics and peri-operative events that were associated with inability to be discharged after Stage 1 palliation (S1P). Analysis of the National Pediatric Cardiology Quality Improvement Collaborative Dataset including patients who underwent a S1P procedure between 2016 and 2019 (Norwood or Hybrid Stage 1 procedure). We examined patient-level characteristics and peri-operative events as possible predictors of inability to discharge after S1P. We constructed multivariate logistic regression models examining post-S1P discharge and in-hospital mortality, adjusting for covariates. 843 patients underwent a S1P and 717 (85%) patients were discharged home or remained inpatient until Stage 2 for social but not medical concerns. Moderate or greater pre-operative atrioventricular valve regurgitation (odds ratio (OR) 4.6, 95% confidence interval (CI) 1.8-12), presence of high-risk pre-operative adverse events (OR 1.5, 95%CI 1.0-2.3), peri-operative events: temporary dialysis (OR 5.4, 95%CI 1.5-18.9), cardiac catheterization or cardiac surgery (OR 2.9, 95%CI 1.8-4.6), sepsis (OR 2.7, 95%CI 1.2-6.2), junctional tachycardia (OR 2.6, 95%CI 1.0-6.3), necrotizing enterocolitis (OR 2.6, 95%CI 1.3-5.2), ECMO (OR 2.5, 95%CI 1.4-4.3), neurological injury (OR 2.1, 95%CI 1.1-4.1), and re-intubation (OR 1.8, 95%CI 1.1-2.9) were associated with inability to discharge after Stage 1. Cardiac anatomical factors, pre-operative adverse events, post-operative re-intubation, post-operative ECMO, infectious complications, and unplanned catheter or surgical re-interventions were associated with inability to discharge after S1P. These findings suggest that quality improvement efforts aimed at reducing these peri-operative events may improve Stage 1 survival and likelihood of discharge.

Atezolizumab and Nab-Paclitaxel in Advanced Triple-Negative Breast Cancer.

BACKGROUND: Unresectable locally advanced or metastatic triple-negative (hormone-receptor-negative and human epidermal growth factor receptor 2 [HER2]-negative) breast cancer is an aggressive disease with poor outcomes. Nanoparticle albumin-bound (nab)-paclitaxel may enhance the anticancer activity of atezolizumab. METHODS: In this phase 3 trial, we randomly assigned (in a 1:1 ratio) patients with untreated metastatic triple-negative breast cancer to receive atezolizumab plus nab-paclitaxel or placebo plus nab-paclitaxel; patients continued the intervention until disease progression or an unacceptable level of toxic effects occurred. Stratification factors were the receipt or nonreceipt of neoadjuvant or adjuvant taxane therapy, the presence or absence of liver metastases at baseline, and programmed death ligand 1 (PD-L1) expression at baseline (positive vs. negative). The two primary end points were progression-free survival (in the intention-to-treat population and PD-L1-positive subgroup) and overall survival (tested in the intention-to-treat population; if the finding was significant, then it would be tested in the PD-L1-positive subgroup). RESULTS: Each group included 451 patients (median follow-up, 12.9 months). In the intention-to-treat analysis, the median progression-free survival was 7.2 months with atezolizumab plus nab-paclitaxel, as compared with 5.5 months with placebo plus nab-paclitaxel (hazard ratio for progression or death, 0.80; 95% confidence interval [CI], 0.69 to 0.92; P=0.002); among patients with PD-L1-positive tumors, the median progression-free survival was 7.5 months and 5.0 months, respectively (hazard ratio, 0.62; 95% CI, 0.49 to 0.78; P<0.001). In the intention-to-treat analysis, the median overall survival was 21.3 months with atezolizumab plus nab-paclitaxel and 17.6 months with placebo plus nab-paclitaxel (hazard ratio for death, 0.84; 95% CI, 0.69 to 1.02; P=0.08); among patients with PD-L1-positive tumors, the median overall survival was 25.0 months and 15.5 months, respectively (hazard ratio, 0.62; 95% CI, 0.45 to 0.86). No new adverse effects were identified. Adverse events that led to the discontinuation of any agent occurred in 15.9% of the patients who received atezolizumab plus nab-paclitaxel and in 8.2% of those who received placebo plus nab-paclitaxel. CONCLUSIONS: Atezolizumab plus nab-paclitaxel prolonged progression-free survival among patients with metastatic triple-negative breast cancer in both the intention-to-treat population and the PD-L1-positive subgroup. Adverse events were consistent with the known safety profiles of each agent. (Funded by F. Hoffmann-La Roche/Genentech; IMpassion130 ClinicalTrials.gov number, NCT02425891 .).

The efficacy and safety of enzalutamide with trastuzumab in patients with HER2+ and androgen receptor-positive metastatic or locally advanced breast cancer.

PURPOSE: Androgen receptor (AR) expression occurs in up to 86% of human epidermal growth factor receptor 2-positive (HER2+) breast cancers. In vitro, AR inhibitors enhance antitumor activity of trastuzumab, an anti-HER2 antibody, in trastuzumab-resistant HER2+ cell lines. This open-label, single-arm, phase II study evaluated the efficacy and safety of enzalutamide, an AR-signaling inhibitor, in patients with advanced HER2+ AR+ breast cancer previously treated with trastuzumab. METHODS: Eligible patients had measurable or non-measurable evaluable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, Eastern Cooperative Oncology Group status ≤ 1, no history of brain metastases, and previously received ≥ 1 anti-HER2 regimen for advanced disease. Patients received 160 mg oral enzalutamide daily and 6 mg/kg intravenous trastuzumab every 21 days until disease progression or unacceptable toxicity. Primary end point was clinical benefit rate at 24 weeks (CBR24); secondary end points included progression-free survival (PFS) and safety. RESULTS: Overall, 103 women were enrolled [median age 60 years (range 34-83)]; 62% had received ≥ 3 lines of prior anti-HER2 therapy. CBR24, comprising patients with confirmed partial responses (5%) and durable stable disease at 24 weeks (19%), was 24% in the efficacy evaluable set (n = 89). CBR24 did not seem related to AR-expression levels or hormone receptor status. Median PFS was 3.4 months (95% confidence interval 2.0-3.8). Overall, 97 (94%) patients experienced treatment-emergent adverse events (TEAEs), with fatigue most common (34%). Dyspnea (4%) and malignant neoplasm progression (3%) were the only TEAEs grade ≥ 3 reported in ≥ 3 patients. 22 patients (21%) reported serious TEAEs. Four patients (4%) experienced fatal, non-drug-related TEAEs. CONCLUSIONS: Enzalutamide plus trastuzumab was well tolerated, and a subset of patients in this heavily pretreated population had durable disease control. Determination of biomarkers is needed to identify patients most likely to benefit from this combination. CLINICALTRIALS. GOV NUMBER: NCT02091960.

Longitudinal Assessment of Right Ventricular Function in Hypoplastic Left Heart Syndrome.

Overall survival of patients with hypoplastic left heart syndrome (HLHS) has shown continued improvement. Right ventricular (RV) dysfunction, in the long term, adversely affects prognosis in these patients. This study examines changes in echocardiographic markers of RV function in a longitudinal cohort. We retrospectively reviewed patients with HLHS managed at our institution from 7/1994 to 1/2016. Follow-up included surgical and clinical data, and echocardiographic measures. Measures of RV function preceding and following all three stages of single ventricular palliation were collected. Freedom from transplant-free survival was assessed by Kaplan-Meier analysis. Multivariable associations with time to death or transplant were explored using the Cox proportional hazards model. A total of 120 patients with HLHS were identified. Norwood operation was performed in all patients. The probability of survival for the cohort was 71 ± 4.4%, 69 ± 4.5% and 66 ± 4.7% at 1, 2 and 5 years respectively after stage I Norwood operation. RV fractional area change (FAC), compared to post-Norwood was decreased at all subsequent stages with the greatest change noted post-superior cavo-pulmonary shunt from 40.7 ± 9.3% to 31.1 ± 8.3% (p < 0.001). Similarly, tricuspid valve annular systolic excursion (TAPSE) Z-score declined from -2.9 ± 1.3 to -9.7 ± 1.3 (p < 0.001) with a decrement at every stage of evaluation. In comparison to patients with post-Norwood RV FAC >35% and TAPSE Z-score > -5, patients with RV FAC ≤ 35% and TAPSE Z-score ≤ -5 had a significantly lower transplant-free survival (p < 0.0001). In patients with HLHS undergoing staged palliation, decrement in RV function manifests longitudinally. Post-Norwood RV FAC and TAPSE Z-score appear to be early markers of poor outcome in this population.

Does liver biopsy accurately measure fibrosis in Fontan-associated liver disease? A comparison of liver biopsy pre-combined heart and liver transplant and liver explant post-transplant.

The accuracy of liver biopsy to stage fibrosis due to Fontan-associated liver disease (FALD) remains unclear. We compared the results of biopsy pre-combined heart and liver transplantation (CHLT) to the results of whole liver explant. Liver biopsy and explants from 15 Fontan patients (ages 16-49, median 28 years) were retrospectively reviewed. Staging was as follows: stage 0: no fibrosis, stage 1: pericellular fibrosis, stage 2: bridging fibrosis, and stage 3: regenerative nodules. There is no stage 4. Clinical characteristics including Model of End-stage Liver Disease eXcluding INR and Varices, Ascites, Splenomegaly, and Thrombocytopenia (VAST) scores were collected, and descriptive statistics and Mann-Whitney U tests were used to analyze the data. All patients had biopsies with at least bridging fibrosis, and all had nodularity on explant; transjugular biopsy never overestimated fibrosis. Explant showed higher-grade fibrosis (stage 3) than pre-CHLT biopsy (stage 2) in 6 of 15 patients and equal grade of fibrosis (stage 3) in 9 of 15 patients. Though clinical characteristics varied significantly, VAST score was ≥2 in all but two patients. Transjugular liver biopsy does not overestimate and can underestimate fibrosis in Fontan patients undergoing CHLT, likely due to the patchy nature of fibrosis in FALD.

The Fontan outcomes network: first steps towards building a lifespan registry for individuals with Fontan circulation in the United States.

The Fontan Outcomes Network was created to improve outcomes for children and adults with single ventricle CHD living with Fontan circulation. The network mission is to optimise longevity and quality of life by improving physical health, neurodevelopmental outcomes, resilience, and emotional health for these individuals and their families. This manuscript describes the systematic design of this new learning health network, including the initial steps in development of a national, lifespan registry, and pilot testing of data collection forms at 10 congenital heart centres.

Trilaciclib plus chemotherapy versus chemotherapy alone in patients with metastatic triple-negative breast cancer: a multicentre, randomised, open-label, phase 2 trial.

BACKGROUND: Trilaciclib is an intravenous cell-cycle inhibitor that transiently maintains immune cells and haemopoietic stem and progenitor cells in G1 arrest. By protecting the immune cells and bone marrow from chemotherapy-induced damage, trilaciclib has the potential to optimise antitumour activity while minimising myelotoxicity. We report safety and activity data for trilaciclib plus gemcitabine and carboplatin chemotherapy in patients with metastatic triple-negative breast cancer. METHODS: In this randomised, open-label, multicentre, phase 2 study, adult patients (aged ≥18 years) with evaluable, biopsy-confirmed, locally recurrent or metastatic triple-negative breast cancer who had no more than two previous lines of chemotherapy were recruited from 26 sites in the USA, three in Serbia, two in North Macedonia, one in Croatia, and one in Bulgaria; sites were academic and community hospitals. Availability of diagnostic samples of tumour tissue confirming triple-negative breast cancer was a prerequisite for enrolment. Eligible patients were randomly assigned (1:1:1) by an interactive web-response system, stratified by number of previous lines of systemic therapy and the presence of liver metastases, to receive intravenous gemcitabine 1000 mg/m2 and intravenous carboplatin (area under the concentration-time curve 2 µg × h/mL) on days 1 and 8 (group 1), gemcitabine and carboplatin plus intravenous trilaciclib 240 mg/m2 on days 1 and 8 (group 2), or gemcitabine and carboplatin on days 2 and 9 plus trilaciclib on days 1, 2, 8, and 9 (group 3) of 21-day cycles. Patients continued treatment until disease progression, unacceptable toxicity, withdrawal of consent, or discontinuation by the investigator. The primary objective was to assess the safety and tolerability of combining trilaciclib with gemcitabine and carboplatin chemotherapy. The primary endpoints were duration of severe neutropenia during cycle 1 and the occurrence of severe neutropenia during the treatment period. Overall survival was included as a key secondary endpoint. Analyses were in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study treatment. This study is registered with EudraCT, 2016-004466-26, and ClinicalTrials.gov, NCT02978716, and is ongoing but closed to accrual. FINDINGS: Between Feb 7, 2017, and May 15, 2018, 142 patients were assessed for eligibility and 102 were randomly assigned to group 1 (n=34), group 2 (n=33), or group 3 (n=35). Of all patients, 38 (37%) had received one or two lines of previous chemotherapy in the metastatic setting. Median follow-up was 8·4 months (IQR 3·8-13·6) for group 1, 12·7 months (5·5-17·4) for group 2, and 12·9 months (6·7-16·8) for group 3. Data cutoff for myelosuppression endpoints was July 30, 2018, and for antitumour activity endpoints was May 17, 2019. During cycle 1, mean duration of severe neutropenia was 0·8 day (SD 2·4) in group 1, 1·5 days (3·5) in group 2, and 1·0 day (2·6) in group 3 (group 3 vs group 1 one-sided adjusted p=0·70). Severe neutropenia occurred in nine (26%) of 34 patients in group 1, 12 (36%) of 33 patients in group 2, and eight (23%) of 35 patients in group 3 (p=0·70). Overall survival was 12·6 months (IQR 5·8-15·6) in group 1, 20·1 months (9·4-not reached) in group 2, and 17·8 months (8·8-not reached) in group 3 (group 3 vs group 1 two-sided p=0·0023). The most common treatment-emergent adverse events were anaemia (22 [73%] of 34), neutropenia (21 [70%]), and thrombocytopenia (18 [60%]) in group 1; neutropenia (27 [82%] of 33), thrombocytopenia (18 [55%]) and anaemia (17 [52%]) in group 2; and neutropenia (23 [66%] of 35), thrombocytopenia (22 [63%]), and nausea (17 [49%]) in group 3. There were no treatment-related deaths. INTERPRETATION: No significant differences were observed in myelosuppression endpoints with trilaciclib plus gemcitabine and carboplatin in patients with metastatic triple-negative breast cancer; however, the regimen was generally well tolerated and overall survival results were encouraging. Further studies of trilaciclib in this setting are warranted. FUNDING: G1 Therapeutics.

Surveillance Testing and Preventive Care After Fontan Operation: A Multi-Institutional Survey.

More children with single ventricle heart disease are surviving after Fontan surgery. This circulation has pervasive effects on multiple organ systems and has unique modes of failure. Many centers have created multidisciplinary programs to care for these patients. Our aim was to survey such programs to better understand current approaches to care. We hypothesized that significant variability in surveillance testing strategy would be present. Eleven academic institutions with established Fontan care programs performing a combined estimated 300 Fontan surgeries per year, with a total population of 1500-2000 Fontan patients, were surveyed using a REDCap survey regarding surveillance testing and basic practice philosophies. Fontan care programs were structured both as consultative services (64%) and as the primary clinical team (9%). Electrocardiograms (73%) and echocardiograms (64%) were most commonly obtained annually. Serum studies, including complete blood count (73%), complete metabolic panel (73%), and Brain-type natriuretic peptide (54%), were most commonly obtained annually. Hepatic testing consisted of liver ultrasound in most centers, obtained biennially (45%) or > every 2 years (45%). Liver biopsy was not routinely recommended (54%). Neurodevelopmental outcomes were assessed at most institutions (54%), with a median frequency of every 3-4 years. There is considerable variability in the surveillance testing regimen and management strategy after a Fontan procedure at surveyed programs. There is an urgent need for surveillance guidelines to reduce variability, define quality metrics, streamline collaborative practice, and prospective research to better understand the complex adaptations of the body to Fontan physiology.

Accuracy of a portable pulse oximeter in monitoring hypoxemic infants with cyanotic heart disease.

OBJECTIVE: Infants with single ventricle physiology have arterial oxygen saturations between 75 and 85%. Home monitoring with daily pulse oximetry is associated with improved interstage survival. They are typically sent home with expensive, bulky, hospital-grade pulse oximeters. This study evaluates the accuracy of both the currently used Masimo LNCS and a relatively inexpensive, portable, and equipped with Bluetooth technology study device, by comparing with the gold standard co-oximeter. DESIGN: Prospective, observational study. SETTING: Single institution, paediatric cardiac critical care unit, and neonatal ICU. INTERVENTIONS: none. PATIENTS: Twenty-four infants under 12 months of age with baseline oxygen saturation less than 90% due to cyanotic CHD. MEASUREMENTS AND RESULTS: Pulse oximetry with WristOx2 3150 with infant sensors 8008 J (study device) and Masimo LCNS saturation sensor connected to a Philips monitor (hospital device) were measured simultaneously and compared to arterial oxy-haemoglobin saturation measured by co-oximetry. Statistical analysis evaluated the performances of each and compared to co-oximetry with Schuirmann's TOST equivalence tests, with equivalence defined as an absolute difference of 5% saturation or less. Neither the study nor the hospital device met the predefined standard for equivalence when compared with co-oximetry. The study device reading was on average 4.0% higher than the co-oximeter, failing to show statistical equivalence (p = 0.16). The hospital device was 7.4% higher than the co-oximeter and also did not meet the predefined standard for equivalence (p = 0.97). CONCLUSION: Both devices tended to overestimate oxygen saturation in this patient population when compared to the gold standard, co-oximetry. The study device is at least as accurate as the hospital device and offers the advantage of being more portable with Bluetooth technology that allows reliable, efficient data transmission. Currently FDA-approved, smaller portable pulse oximeters can be considered for use in home monitoring programmes.

Younger age remains a risk factor for prolonged length of stay after bidirectional cavopulmonary anastomosis.

OBJECTIVE: This study sets out to determine the influence of age at the time of surgery as a risk factor for post-operative length of stay after bidirectional cavopulmonary anastomosis. METHODS: All patients undergoing a Glenn procedure between January 2010 and July 2015 were included in this retrospective cohort study. Demographic data were examined. Standard descriptive statistics was used. A univariable analysis was conducted using the appropriate test based on data distribution. A propensity score for balancing the group difference was included in the multi-variable analysis, which was then completed using predictors from the univariable analysis that achieved significance of p<0.1. RESULTS: Over the study period, 50 patients met the inclusion criteria. Patients were separated into two cohorts of ⩾4 months (28 patients) and <4 months (22 patients). Other than height and weight, the two cohorts were indistinguishable in their pre-operative saturation, medications, catheterisation haemodynamics, atrioventricular valve regurgitation, and ventricular function. After adjusting group differences, younger age was associated with longer post-operative length of hospitalisation - adjusted mean 15 (±2.53) versus 8 (±2.15) days (p=0.03). In a multi-variable regression analysis, in addition to ventricular dysfunction (ß coefficient=8.8, p=0.05), Glenn procedures performed before 4 months were independently associated with longer length of stay (ß coefficient=-6.9, p=0.03). CONCLUSION: We found that Glenn procedures performed after 4 months of age had shorter post-operative length of stay when compared to a younger cohort. These findings suggest that balancing timing of surgery to decrease the inter-stage period should take into consideration differences in post-operative recovery with earlier operations.

A randomized, double-blind, phase 2 study of ruxolitinib or placebo in combination with capecitabine in patients with advanced HER2-negative breast cancer and elevated C-reactive protein, a marker of systemic inflammation.

PURPOSE: The Janus-associated kinase (JAK)/signal transducer and activator of transcription pathway is a key regulator of inflammatory signaling, associated with tumorigenesis, cell survival, and progression. This randomized phase 2 trial evaluated the efficacy and safety of the addition of ruxolitinib, a JAK1/JAK2 inhibitor, to capecitabine in patients with HER2-negative advanced breast cancer and high systemic inflammation (modified Glasgow Prognostic Score [mGPS] ≥ 1). METHODS: Patients with ≤ 2 prior chemotherapy regimens for advanced or metastatic disease or hormone receptor-positive patients with disease progression on prior hormonal therapies were randomized 1:1 to 21-day cycles of ruxolitinib (n = 76) or placebo (n = 73) plus capecitabine. The primary endpoint was overall survival (OS). RESULTS: Baseline characteristics were well balanced between groups. For ruxolitinib plus capecitabine versus placebo plus capecitabine, median OS was 11.2 months versus 10.9 months (log-rank test P = 0.762); median progression-free survival (PFS) was 4.5 months versus 2.5 months (log-rank test P = 0.151); and overall response rate (ORR) was 28.9% versus 13.7% (Cochran-Mantel-Haenszel test P = 0.024), respectively. A more favorable change in health-related quality of life (HRQoL) was observed with ruxolitinib plus capecitabine versus placebo plus capecitabine. Both regimens were generally tolerable. A higher incidence of grade 3/4 anemia (25.4% vs 5.6%) and a lower incidence of grade 3/4 palmar-plantar erythrodysesthesia (1.4% vs 12.7%) occurred with ruxolitinib plus capecitabine versus placebo plus capecitabine. CONCLUSIONS: The addition of ruxolitinib to capecitabine for patients with advanced breast cancer and high systemic inflammation was generally tolerable; ORR was numerically greater, a more favorable change in HRQoL was observed, but neither OS nor PFS was improved compared with placebo plus capecitabine.

One hundred useful references in pediatric cardiac intensive care: the 2012 update.

OBJECTIVE: The specialty of pediatric cardiac critical care has undergone rapid scientific and clinical growth in the last 25 years. The Board of Directors of the Pediatric Cardiac Intensive Care Society assembled an updated list of sentinel references focused on the critical care of children with congenital and acquired heart disease. We encouraged board members to select articles that have influenced and informed their current practice or helped to establish the standard of care. The objective of this article is to provide clinicians with a compilation and brief summary of these updated 100 useful references. DATA SOURCES: The list of 'One Hundred Useful References for Pediatric Cardiac Intensive Care' (2004) and relevant literature to the practice of cardiac intensive care. DATA SELECTION: A subset of Pediatric Cardiac Intensive Care Society board members compiled the initial list of useful references in 2004, which served as the basis of the new updated list. Suggestions for relevant articles were submitted by the Pediatric Cardiac Intensive Care Society board members and selected pediatric cardiac intensivists with an interest in this project following the Society's meeting in 2010. Articles were considered for inclusion if they were named in the original list from 2004 or were suggested by Pediatric Cardiac Intensive Care Society board members and published before December 31, 2011. DATA EXTRACTION: Following submission of the complete list by the Pediatric Cardiac Intensive Care Society board and contributing Society members, articles were complied by the two co-first authors (D.A., D.K.). The authors also performed Medline searches to ensure comprehensive inclusion of all relevant articles. The final list was then submitted to the Pediatric Cardiac Intensive Care Society board members, who ranked each publication. DATA SYNTHESIS: Rankings were compiled and the top 100 articles with the highest scores were selected for inclusion in this publication. The two co-first authors (D.A., D.K.) reviewed all existing summaries and developed summaries of the newly submitted articles. CONCLUSIONS: An updated compilation of 100 useful references for the critical care of children with congenital and acquired heart disease has been compiled and summarized here. Clinicians and trainees may wish to use this document as a reference for education in this complex and challenging subspecialty.

The feasibility and acceptability of an online mind-body wellness program for patients with primary biliary cholangitis.

Background: Persons with primary biliary cholangitis (PBC) experience significantly higher rates of mental distress and impaired health related quality of life (HrQoL) than the general population. Given limited evidence, but a high need, our primary aim was to assess feasibility and acceptability of a 12-week, online, mind-body wellness program in people with PBC. Methods: This was a single-group, sequential mixed-methods, pre-post feasibility, and acceptability study. Core program components included follow-along movement, meditation and breathwork videos, and cognitive behavioural therapy informed activities. This was supplemented by weekly phone check-ins. Feasibility was assessed by recruitment, adherence, and retention. The pre-post exploratory efficacy assessment included surveys for fatigue, perceived stress, anxiety, depression, HrQoL, and resilience. A qualitative descriptive approach with semi-structured interviews evaluated study experiences. Results: Thirty-two participants were recruited within 30 days and 29 (91%) were retained to end-of-study. Of these, 25 (86%) adhered to carrying out the mind-body practice at least 2-3 days per week. Feedback supported acceptability (satisfaction score 90%). Significant improvements were observed in fatigue (13%, p = 0.004), anxiety (30%, p = 0.005), depression (28%, p = 0.004), and five PBC-40 domains (itch, fatigue, cognitive, emotional, general symptoms). Qualitative interviews revealed improved stress management, better coping, and a more positive mindset. Fatigue and self-sabotaging thoughts were cited as barriers to participation. Conclusions: These findings suggest that a 12-week online mind-body intervention is feasible and acceptable in patients with PBC. After iterative refinement, a randomized controlled trial will be designed using this feedback.

Impact of Reintervention During Stage 1 Palliation Hospitalization: A National, Multicenter Study.

BACKGROUND: Stage 1 palliation (S1P) for hypoplastic left heart syndrome remains associated with high morbidity and mortality. Previous studies on burden of reinterventions did not include patients who remain hospitalized before stage 2 palliation (S2P). This study described the rate of reintervention during S1P hospitalization and sought to determine the impact of reintervention on outcomes. METHODS: All participants enrolled in phase II of the National Pediatric Cardiology Quality Improvement Collaborative after S1P were included in this study. The primary outcome was the rate of reintervention during hospitalization after S1P and before hospital discharge or S2P. Reintervention was defined as 1 or more unplanned interventional cardiac catheterizations or surgical reoperations. RESULTS: Between March 1, 2016 and October 1, 2019, 1367 participants underwent S1P and 339 (24.8%) had a reintervention; most commonly to address the source of pulmonary blood flow. Gestational age, weight at S1P, atrioventricular septal defect, heterotaxy, preoperative pulmonary artery bands, hybrid S1P, and an additional bypass run or early extracorporeal membrane oxygenation were significantly associated with reintervention. Participants in the reintervention group experienced higher rates of nearly all postoperative complications, were less likely to be discharged before S2P (57.1% vs 86%; P < .001), and more likely to experience in-hospital mortality (17% vs 5%; P < .001). CONCLUSIONS: Unplanned reintervention during hospitalization after S1P palliation occurred in 25% of participants in a large, registry-based national cohort. Participants who underwent reintervention were more likely to remain as inpatient and were less likely to survive to S2P. Reintervention was associated with a multitude of postoperative complications that affect survival and long-term outcome.

An online mind-body program improves mental health and quality of life in primary biliary cholangitis: A randomized controlled trial.

BACKGROUND AND AIMS: People with primary biliary cholangitis (PBC) experience high rates of mental distress and fatigue despite standard of care therapy. We aimed to assess the impact of an online mind-body intervention on these symptoms. METHODS: This 12-week RCT used sequential mixed-methods evaluation. Alongside standard of care, participants with primary biliary cholangitis were randomized to receive weekly countdown emails, or the intervention consisting of (i) a weekly 20-30 minute-mind-body follow-along video, (ii) weekly 5-10-minute psychology-based "managing chronic disease skills videos," and (iii) 10-minute telephone check-ins. The primary outcome was a change in the Hospital Anxiety and Depression Scale (HADS). Secondary outcomes evaluated changes in fatigue, perceived stress, resilience, and health-related quality of life. ANCOVA determined between-group differences. RESULTS: Of the 87 randomized patients (control group: n = 44, intervention group: n = 43), the between-group HADS total score improved by 20.0% (95% CI 4.7, 35.2, p = 0.011). Significant improvements were seen in depression (25.8%), perceived stress (15.2%), and 2 primary biliary cholangitis-40 domains [emotional symptoms (16.3%) and social symptoms (11.8%)] with a mean satisfaction of 82/100. This corresponded with end-of-study qualitative findings. Although no improvements were observed in fatigue in the main analysis, a significant benefit was observed in the subgroup of intervention participants (20/36;56%) who completed the mind-body video routine at least 3 times per week. CONCLUSION: This intervention improved measures of mental wellness and quality of life with high satisfaction and reasonable adherence. Future studies could explore strategies to optimize adherence and target fatigue.

Outcomes After Development of Ventricular Arrhythmias in Single Ventricular Heart Disease Patients With Fontan Palliation.

BACKGROUND: With the advent of more intensive rhythm monitoring strategies, ventricular arrhythmias (VAs) are increasingly detected in Fontan patients. However, the prognostic implications of VA are poorly understood. We assessed the incidence of VA in Fontan patients and the implications on transplant-free survival. METHODS: Medical records of Fontan patients seen at a single center between 2002 and 2019 were reviewed to identify post-Fontan VA (nonsustained ventricular tachycardia >4 beats or sustained >30 seconds). Patients with preFontan VA were excluded. Hemodynamically unstable VA was defined as malignant VA. The primary outcome was death and heart transplantation. Death with censoring at transplant was a secondary outcome. RESULTS: Of 431 Fontan patients, transplant-free survival was 82% at 15 years post-Fontan with 64 (15%) meeting primary outcome of either death (n=16, 3.7%), at a median 4.6 (0.4-10.2) years post-Fontan, or transplant (n=48, 11%), at a median of 11.1 (5.9-16.2) years post-Fontan. Forty-eight (11%) patients were diagnosed with VA (90% nonsustained ventricular tachycardia, 10% sustained ventricular tachycardia). Malignant VA (n=9, 2.0%) was associated with younger age, worse systolic function, and valvular regurgitation. Risk for VA increased with time from Fontan, 2.4% at 10 years to 19% at 20 years. History of Stage 1 surgery with right ventricular to pulmonary artery conduit and older age at Fontan were significant risk factors for VA. VA was strongly associated with an increased risk of transplant or death (HR, 9.2 [95% CI, 4.5-18.7]; P<0.001), with a transplant-free survival of 48% at 5-year post-VA diagnosis. CONCLUSIONS: Ventricular arrhythmias occurred in 11% of Fontan patients and was highly associated with transplant or death, with a transplant-free survival of <50% at 5-year post-VA diagnosis. Risk factors for VA included older age at Fontan and history of right ventricular to pulmonary artery conduit. A diagnosis of VA in Fontan patients should prompt increased clinical surveillance.

Margetuximab Versus Trastuzumab in Patients With Previously Treated HER2-Positive Advanced Breast Cancer (SOPHIA): Final Overall Survival Results From a Randomized Phase 3 Trial.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Final overall survival (OS) in SOPHIA (ClinicalTrials.gov identifier: NCT02492711), a study of margetuximab versus trastuzumab, both with chemotherapy, in patients with previously treated human epidermal growth factor receptor 2-positive advanced breast cancer, is reported with updated safety. Overall, 536 patients in the intention-to-treat population were randomly assigned to margetuximab (15 mg/kg intravenously once every 3 weeks; n = 266) plus chemotherapy or trastuzumab (6 mg/kg intravenously once every 3 weeks after a loading dose of 8 mg/kg; n = 270) plus chemotherapy. Primary end points were progression-free survival, previously reported, and OS. Final OS analysis was triggered by 385 prespecified events. The median OS was 21.6 months (95% CI, 18.89 to 25.07) with margetuximab versus 21.9 months (95% CI, 18.69 to 24.18) with trastuzumab (hazard ratio [HR], 0.95; 95% CI, 0.77 to 1.17; P = .620). Preplanned, exploratory analysis of CD16A genotyping suggested a possible improvement in OS for margetuximab in CD16A-158FF patients versus trastuzumab (median OS, 23.6 v 19.2 months; HR, 0.72; 95% CI, 0.52 to 1.00) and a possible improvement in OS for trastuzumab in CD16A-158VV patients versus margetuximab (median OS, 31.1 v 22.0 months; HR, 1.77; 95% CI, 1.01 to 3.12). Margetuximab safety was comparable with trastuzumab. Final overall OS analysis did not demonstrate margetuximab advantage over trastuzumab. Margetuximab studies in patients with human epidermal growth factor receptor 2-positive breast cancer with different CD16A allelic variants are warranted.

Trilaciclib Prior to Chemotherapy in Patients with Metastatic Triple-Negative Breast Cancer: Final Efficacy and Subgroup Analysis from a Randomized Phase II Study.

PURPOSE: We report final antitumor efficacy results from a phase II study of trilaciclib, an intravenous cyclin-dependent kinase 4/6 (CDK4/6) inhibitor, administered prior to gemcitabine plus carboplatin (GCb) in patients with metastatic triple-negative breast cancer (NCT02978716). PATIENTS AND METHODS: Patients were randomized (1:1:1) to group 1 [GCb (days 1, 8); n = 34], group 2 [trilaciclib prior to GCb (days 1, 8); n = 33], or group 3 [trilaciclib (days 1, 8) and trilaciclib prior to GCb (days 2, 9); n = 35]. Subgroup analyses were performed according to CDK4/6 dependence, level of programmed death-ligand 1 (PD-L1) expression, and RNA-based immune signatures using proportional hazards regression. T-cell receptor (TCR) ß CDR3 regions were amplified and sequenced to identify, quantify, and compare the abundance of each unique TCRß CDR3 at baseline and on treatment. RESULTS: Median overall survival (OS) was 12.6 months in group 1, not reached in group 2 (HR = 0.31; P = 0.0016), 17.8 months in group 3 (HR = 0.40; P = 0.0004), and 19.8 months in groups 2 and 3 combined (HR = 0.37; P < 0.0001). Efficacy outcomes were comparable regardless of cancer CDK4/6 dependence status and immune signatures. Administering trilaciclib prior to GCb prolonged OS irrespective of PD-L1 status but had greater benefit in the PD-L1-positive population. T-cell activation was enhanced in patients receiving trilaciclib. CONCLUSIONS: Administering trilaciclib prior to GCb enhanced antitumor efficacy, with significant improvements in OS. Efficacy outcomes in immunologic subgroups and enhancements in T-cell activation suggest these improvements may be mediated via immunologic mechanisms.
