Cancer mortality in children surviving congenital heart interventions: A study from the Pediatric Cardiac Care Consortium.

INTRODUCTION: Children with congenital heart defects (CHD) have shorter life expectancy than the general population. Previous studies also suggest that patients with CHD have higher risk of cancer. This study aims to describe cancer-related mortality among patients with a history of CHD interventions using the Pediatric Cardiac Care Consortium (PCCC), a large US cohort of such patients. METHODS: We performed a retrospective cohort study of individuals (<21 years) who underwent interventions for CHD in the PCCC from 1982 to 2003. Patients surviving their first intervention were linked to the National Death Index through 2020. Multivariable models assessed risk of cancer-related death, adjusting for age, sex, race, and ethnicity. Patients with/without genetic abnormalities (mostly Down syndrome [DS]) were considered separately, due to expected differential risk in cancer. RESULTS: Among the 57,601 eligible patients in this study, cancer was the underlying or contributing cause of death for 208; with 20% among those with DS. Significantly increased risk of cancer-related death was apparent among patients with DS compared to the non-genetic group (aHR: 3.63, 95% confidence interval [CI]: 2.52-5.24, p < .001). For the group with non-genetic abnormalities, the highest association with cancer-related death compared to those with mild CHD was found among those with more severe CHD (severe two-ventricle aHR: 1.82, 95% CI: 1.04-3.20, p = .036, single-ventricle aHR: 4.68, 95% CI: 2.77-7.91, p < .001). CONCLUSIONS: Patients with more severe forms of CHD are at increased risk for cancer-related death. Despite our findings, we are unable to distinguish whether having CHD raises the risk of cancer or reduces survival.

Evaluating the perceived impact and legacy of master's degree level research in the allied health professions: a UK-wide cross-sectional survey.

BACKGROUND: Post graduate master's degree qualifications are increasingly required to advance allied health profession careers in education, clinical practice, leadership, and research. Successful awards are dependent on completion of a research dissertation project. Despite the high volume of experience gained and research undertaken at this level, the benefits and impact are not well understood. Our study aimed to evaluate the perceived impact and legacy of master's degree training and research on allied health profession practice and research activity. METHODS: A cross-sectional online survey design was used to collect data from allied health professionals working in the United Kingdom who had completed a postgraduate master's degree. Participants were recruited voluntarily using social media and clinical interest group advertisement. Data was collected between October and December 2022 and was analysed using descriptive statistics and narrative content analysis. Informed consent was gained, and the study was approved by the university research ethics committee. RESULTS: Eighty-four responses were received from nine allied health professions with paramedics and physiotherapists forming the majority (57%) of respondents. Primary motivation for completion of the master's degree was for clinical career progression (n = 44, 52.4%) and formation of the research dissertation question was predominantly sourced from individual ideas (n = 58, 69%). Formal research output was low with 27.4% (n = 23) of projects published in peer reviewed journal and a third of projects reporting no output or dissemination at all. Perceived impact was rated highest in individual learning outcomes, such as improving confidence and capability in clinical practice and research skills. Ongoing research engagement and activity was high with over two thirds (n = 57, 67.9%) involved in formal research projects. CONCLUSION: The focus of master's degree level research was largely self-generated with the highest perceived impact on individual outcomes rather than broader clinical service and organisation influence. Formal output from master's research was low, but ongoing research engagement and activity was high suggesting master's degree training is an under-recognised source for AHP research capacity building. Future research should investigate the potential benefits of better coordinated and prioritised research at master's degree level on professional and organisational impact.

Medicaid Enrollment and Intergenerational Transfers of Wealth Among Older Adults.

BACKGROUND AND OBJECTIVES: Medicaid look-back periods are meant to prevent Medicaid applicants from gifting assets to meet eligibility requirements. These policies have the potential to affect families across generations given their ability to restrict the transfer of assets between parent and child. RESEARCH DESIGN AND METHODS: Using 2008-2018 data from the Health and Retirement Study, this study analyzed the estate planning and familial wealth transfer behaviors of a cohort of older adults aged 65 and older who became Medicaid recipients during a 10-year period. RESULTS: There were 8,347 respondents aged 65 and older in 2008 and 11.96% of respondents who were not Medicaid recipients at baseline became recipients over the study period. A little more than one third (36.47%) of Medicaid recipients participated in estate planning and asset transfer prior to becoming a recipient, with significant differences among select demographic characteristics. Married recipients were more likely to transfer money compared to their widowed counterparts (51.69% compared to 36.44%; p < .001) and transferred larger amounts compared to those unmarried ($16,286.94 compared to 5,379.13). White, well-educated, married, men participated in higher rates of estate planning, likely a reflection of who has access to resources to make necessary arrangements early. DISCUSSION AND IMPLICATIONS: This analysis concludes that more structurally advantaged groups are more likely to engage in estate planning prior to Medicaid enrollment. This analysis demonstrates that some individuals may circumvent Medicaid policies like look-back periods and estate recovery, while others cannot. Policymakers should consider policies that promote the financial health of low-income families.

Long-term Outcomes After Interrupted Aortic Arch Repair.

BACKGROUND: Interrupted aortic arch (IAA) is associated with left ventricular outflow tract obstruction (LVOTO) and DiGeorge syndrome. High-risk infantile surgery is required to address IAA, with limited data available on long-term outcomes. We used the Pediatric Cardiac Care Consortium, a multicenter US-based registry for pediatric cardiac interventions, to assess long-term outcomes after IAA repair by patient characteristics and surgical approach. METHODS: This is a retrospective cohort study of patients undergoing IAA repair between 1982 and 2003. Kaplan-Meier plots and Cox proportional hazards regression were used to examine associations with postdischarge deaths tracked by matching with the US National Death Index. RESULTS: Of 390 patients meeting inclusion criteria, 309 (79.2%) survived to discharge. During a median follow-up of 23.6 years, 30-year survival reached 80.7% for patients surviving hospital discharge after initial IAA repair. Adjusted analysis revealed higher risk of death for type B vs type A (adjusted hazard ratio [aHR], 3.32; 95% CI, 1.48-7.44), staged repair (aHR, 2.50; 95% CI, 1.14-5.50), and LVOTO interventions during initial hospitalization (aHR, 4.12; 95% CI, 1.83-9.27) but not for LVOTO without need for interventions or presence of DiGeorge syndrome. There was a trend toward improved in-hospital and long-term survival over time during the study period. CONCLUSIONS: Staged repair, type B IAA, and need for LVOTO intervention during initial hospitalization for repair are associated with high risk of death out to 30 years. Survival outcomes are improving, but further efforts need to minimize staged approach and risks associated with LVOTO relief procedures.

Long-term Outcomes After Surgical Intervention for Congenital Supravalvar Aortic Stenosis in Children.

BACKGROUND: Primary supravalvar aortic stenosis (SVAS) is a rare congenital cardiovascular condition that can coexist with Williams-Beuren syndrome, coronary artery involvement, aortic coarctation, and pulmonary artery stenosis. SVAS repair can be achieved with low perioperative mortality, but long-term survival remains less well understood. We used the Pediatric Cardiac Care Consortium, a multicenter United States-based registry for pediatric cardiac operations, to assess long-term outcomes after SVAS repair. METHODS: We used Kaplan-Meier plots and Cox proportional hazards regression to examine factors associated with postdischarge deaths. These included sex, age-group, weight z-score, coexisting conditions (Williams-Beuren syndrome, coronary artery involvement, coarctation, and pulmonary artery stenosis), surgical techniques, and era, defined as early (1982-1995) or late (1996-2003). Survival was assessed by matching with the National Death Index through 2021. RESULTS: Of 333 patients who met inclusion criteria, 313 (94.0%) survived to discharge and 188 (60.1%) had identifiers for National Death Index matching. Over a median follow-up of 25.2 years (interquartile range, 21.1-29.4 years), 17 deaths occurred. The 30-year survival after discharge from SVAS repair was 88.7% (95% CI, 82.9%-94.8%). Infantile surgery and non-Williams-Beuren syndrome were associated with decreased 30-year survival. From the various repairs, the 2-sinus technique had better outcomes compared with all other types, except the 3-sinus technique (nonsignificant difference). Adjusted analysis revealed infantile age and type of repair as associated with postdischarge probability of death. CONCLUSIONS: These data demonstrate favorable long-term outcomes after SVAS repair, except for the infantile group that was associated with more diffuse arteriopathy. As techniques continue to evolve, future studies are warranted to investigate their long-term outcomes.

Mechanisms and management of loss of response to anti-TNF therapy for patients with Crohn's disease: 3-year data from the prospective, multicentre PANTS cohort study.

BACKGROUND: We sought to report the effectiveness of infliximab and adalimumab over the first 3 years of treatment and to define the factors that predict anti-TNF treatment failure and the strategies that prevent or mitigate loss of response. METHODS: Personalised Anti-TNF therapy in Crohn's disease (PANTS) is a UK-wide, multicentre, prospective observational cohort study reporting the rates of effectiveness of infliximab and adalimumab in anti-TNF-naive patients with active luminal Crohn's disease aged 6 years and older. At the end of the first year, sites were invited to enrol participants still receiving study drug into the 2-year PANTS-extension study. We estimated rates of remission across the whole cohort at the end of years 1, 2, and 3 of the study using a modified survival technique with permutation testing. Multivariable regression and survival analyses were used to identify factors associated with loss of response in patients who had initially responded to anti-TNF therapy and with immunogenicity. Loss of response was defined in patients who initially responded to anti-TNF therapy at the end of induction and who subsequently developed symptomatic activity that warranted an escalation of steroid, immunomodulatory, or anti-TNF therapy, resectional surgery, or exit from study due to treatment failure. This study was registered with ClinicalTrials.gov, NCT03088449, and is now complete. FINDINGS: Between March 19, 2014, and Sept 21, 2017, 389 (41%) of 955 patients treated with infliximab and 209 (32%) of 655 treated with adalimumab in the PANTS study entered the PANTS-extension study (median age 32·5 years [IQR 22·1-46·8], 307 [51%] of 598 were female, and 291 [49%] were male). The estimated proportion of patients in remission at the end of years 1, 2, and 3 were, for infliximab 40·2% (95% CI 36·7-43·7), 34·4% (29·9-39·0), and 34·7% (29·8-39·5), and for adalimumab 35·9% (95% CI 31·2-40·5), 32·9% (26·8-39·2), and 28·9% (21·9-36·3), respectively. Optimal drug concentrations at week 14 to predict remission at any later timepoints were 6·1-10·0 mg/L for infliximab and 10·1-12·0 mg/L for adalimumab. After excluding patients who had primary non-response, the estimated proportions of patients who had loss of response by years 1, 2, and 3 were, for infliximab 34·4% (95% CI 30·4-38·2), 54·5% (49·4-59·0), and 60·0% (54·1-65·2), and for adalimumab 32·1% (26·7-37·1), 47·2% (40·2-53·4), and 68·4% (50·9-79·7), respectively. In multivariable analysis, loss of response at year 2 and 3 for patients treated with infliximab and adalimumab was predicted by low anti-TNF drug concentrations at week 14 (infliximab: hazard ratio [HR] for each ten-fold increase in drug concentration 0·45 [95% CI 0·30-0·67], adalimumab: 0·39 [0·22-0·70]). For patients treated with infliximab, loss of response was also associated with female sex (vs male sex; HR 1·47 [95% CI 1·11-1·95]), obesity (vs not obese 1·62 [1·08-2·42]), baseline white cell count (1·06 [1·02-1·11) per 1 × 109 increase in cells per L), and thiopurine dose quartile. Among patients treated with adalimumab, carriage of the HLA-DQA1*05 risk variant was associated with loss of response (HR 1·95 [95% CI 1·17-3·25]). By the end of year 3, the estimated proportion of patients who developed anti-drug antibodies associated with undetectable drug concentrations was 44·0% (95% CI 38·1-49·4) among patients treated with infliximab and 20·3% (13·8-26·2) among those treated with adalimumab. The development of anti-drug antibodies associated with undetectable drug concentrations was significantly associated with treatment without concomitant immunomodulator use for both groups (HR for immunomodulator use: infliximab 0·40 [95% CI 0·31-0·52], adalimumab 0·42 [95% CI 0·24-0·75]), and with carriage of HLA-DQA1*05 risk variant for infliximab (HR for carriage of risk variant: infliximab 1·46 [1·13-1·88]) but not for adalimumab (HR 1·60 [0·92-2·77]). Concomitant use of an immunomodulator before or on the day of starting infliximab was associated with increased time without the development of anti-drug antibodies associated with undetectable drug concentrations compared with use of infliximab alone (HR 2·87 [95% CI 2·20-3·74]) or introduction of an immunomodulator after anti-TNF initiation (1·70 [1·11-2·59]). In years 2 and 3, 16 (4%) of 389 patients treated with infliximab and 11 (5%) of 209 treated with adalimumab had adverse events leading to treatment withdrawal. Nine (2%) patients treated with infliximab and two (1%) of those treated with adalimumab had serious infections in years 2 and 3. INTERPRETATION: Only around a third of patients with active luminal Crohn's disease treated with an anti-TNF drug were in remission at the end of 3 years of treatment. Low drug concentrations at the end of the induction period predict loss of response by year 3 of treatment, suggesting higher drug concentrations during the first year of treatment, particularly during induction, might lead to better long-term outcomes. Anti-drug antibodies associated with undetectable drug concentrations of infliximab, but not adalimumab, can be predicted by carriage of HLA-DQA1*05 and mitigated by concomitant immunomodulator use for both drugs.
