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.

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.

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.

Survival After Single-Stage Repair of Truncus Arteriosus and Associated Defects.

BACKGROUND: The goal of this study was to describe in-hospital and long-term mortality after single-stage repair of truncus arteriosus communis (TAC) and explore factors associated with these outcomes. METHODS: This was a cohort study of consecutive patients undergoing single-stage TAC repair between 1982 and 2011 reported to the Pediatric Cardiac Care Consortium registry. In-hospital mortality was obtained for the entire cohort from registry records. Long-term mortality was obtained for patients with available identifiers by matching with the National Death Index through 2020. Kaplan-Meier survival estimates were created for up to 30 years after discharge. Cox regression models estimated hazard ratios for the associations with potential risk factors. RESULTS: A total of 647 patients (51% male) underwent single-stage TAC repair at a median age of 18 days; 53% had type I TAC, 13% had interrupted aortic arch, and 10% underwent concomitant truncal valve surgery. Of these, 486 (75%) patients survived to hospital discharge. After discharge, 215 patients had identifiers for tracking long-term outcomes; 30-year survival was 78%. Concomitant truncal valve surgery at the index procedure was associated with increased in-hospital and 30-year mortality. Concomitant interrupted aortic arch repair was not associated with increased in-hospital or 30-year mortality. CONCLUSIONS: Concomitant truncal valve surgery but not interrupted aortic arch was associated with higher in-hospital and long-term mortality. Careful consideration of the need and timing for truncal valve intervention may improve TAC outcomes.

The First Sign of Recurrent Angioimmunoblastic T-Cell Lymphoma: A Cutaneous Presentation.

Angioimmunoblastic T-cell lymphoma (AITL) is a subtype of peripheral T-cell lymphoma with a nonspecific clinical presentation. Cutaneous manifestations of AITL are variable and include morbilliform eruptions, urticaria, papulonodules, and erythroderma. We present the case of a 74-year-old male with a medical history of AITL presenting with diffuse erythematous macules and papules coalescing into patches and plaques on the trunk and bilateral upper extremities. Histopathology demonstrated a mild perivascular lymphocytic infiltrate in the dermis. By immunohistochemistry, the lymphocytic infiltrate was strongly positive for programmed cell death protein 1 (PD-1) (CD279) as well as cluster of differentiation 3 (CD3), CD5, and (focally) B-cell lymphoma-6 (BCL-6). Many cells within the infiltrate were positive for Epstein-Barr virus (EBV) by in situ hybridization. Additionally, a bone marrow biopsy demonstrated an atypical lymphoid infiltrate with T-cell predominance, many EBV-positive cells, and clonal T-cell receptor (TCR) beta gene rearrangement. Based on these histopathological findings, a diagnosis of recurrent AITL with cutaneous involvement was made. This case is a rare example of skin findings presenting as a first sign of recurrent AITL.

Coexisting ions and long-chain per- and polyfluoroalkyl substances (PFAS) inhibit the adsorption of short-chain PFAS by granular activated carbon.

We assessed the competitive adsorption between long-chain and short-chain PFAS and the impact of coexisting ions to understand the mechanisms leading to the early breakthrough of short-chain PFAS from granular activated carbon (GAC) filters. Three pairs of short-chain and long-chain PFAS representing different functional groups were studied using GAC (Filtrasorb 400) in batch systems. In bisolute systems, the presence of long-chain PFAS decreased the adsorption of short-chain PFAS by 30-50% compared to their single solute adsorption capacity (0.22-0.31 mmol/g). In contrast to the partial decrease observed in bisolute systems, the addition of long-chain PFAS to GAC pre-equilibrated with short-chain PFAS completely desorbed all short-chain PFAS from GAC. This suggested that the outermost adsorption sites on GAC were preferentially occupied by short-chain PFAS in the absence of competition but were prone to displacement by long-chain PFAS. The presence of inorganic/organic ions inhibited the adsorption of short-chain PFAS (up to 60%) but had little to no impact on long-chain PFAS, with the inhibitory trend inversely correlated with Kow values. Study results indicated that the displacement of short-chain PFAS by long-chain PFAS and charge neutralization are important mechanisms contributing to the early breakthrough of short-chain PFAS from GAC systems.

Procedure-Specific Center Volume and Mortality After Infantile Congenital Heart Surgery.

BACKGROUND: Regionalization of congenital heart surgery (CHS) has been proposed to improve postsurgical outcomes by increasing experience in the care of high-risk patients. We sought to determine whether procedure-specific center volume was associated with mortality after infantile CHS up to 3 years post-procedure. METHODS: We analyzed data from 12,263 infants in the Pediatric Cardiac Care Consortium undergoing CHS between 1982 and 2003 at 46 centers within the United States. We used logistic regression to assess the association between procedure-specific center volume and mortality from discharge to 3 years post-procedure, accounting for clustering at the center level and adjusting for patient age and weight at surgery, chromosomal abnormality, and surgical era. RESULTS: We found decreased odds for in-hospital mortality for Norwood procedures (odds ratio [OR] 0.955, 95% CI 0.935-0.976), arterial switch operations (OR 0.924, 95% CI 0.889-0.961), tetralogy of Fallot repairs (OR 0.975, 95% CI 0.956-0.995), Glenn shunts (OR 0.971, 95% CI 0.943-1.000), and ventricular septal defect closures (OR 0.974, 95% CI 0.964-0.985). The association persisted up to 3 years post-surgery for Norwood procedures (OR 0.971, 95% CI 0.955-0.988), arterial switches (OR 0.929, 95% CI 0.890-0.970), and ventricular septal defect closures (OR 0.986, 95% CI 0.977-0.995); however, after excluding deaths that occurred within the first 90 days of following surgery, we observed no association between center volume and mortality for any of the procedures studied. CONCLUSIONS: These findings suggest that procedure-specific center volume is inversely associated with early postoperative mortality for infantile CHS across the complexity spectrum but has no measurable effect on later mortality.

The Ever-Changing Work Environment During COVID-19: Nurses' Experiences in the Early Phase.

The COVID-19 pandemic is a history-changing event affecting all nurses. This study sought to explore nurses' experiences during the pandemic's early phase using a phenomenological approach. One hundred sixty-one participants enrolled in the study. Demographic data, written narratives, and digital images were collected. Ever-changing environment emerged as the overarching theme, along with six subthemes. Because of a crisis situation created by the pandemic, nurses need specialized support and education to manage their constantly changing environment.

Using a Brief Intervention to Improve Partner-Focused Conversation in Adolescents with Autism.

Individuals on the autism spectrum often experience pragmatic social conversation difficulties that include showing interest in their conversational partners. This may become particularly evident during adolescence when conversation with peers is the primary medium for social interaction. This study used a multiple baseline design across participants to investigate the effects of a brief intervention package on the partner-focused conversation of three adolescents with autism. Results showed increased partner-focused questions and comments for all participants. Social validity assessments indicated that the intervention led to meaningful improvements in peer conversations.

NASW's Supervisory Leaders in Aging: One-year practice change outcomes of an innovative training program for social work supervisors.

Social work supervision addresses professional development, staff support, and management of direct service workers. It is important in aging-services settings because of the impacts of complex and evolving biopsychosocial forces in clients' lives. This article presents findings of the Supervisory Leaders in Aging (SLA) study based on data available one-year post completion. SLA is a 30-hour certificate program for supervisors from aging-services settings addressing best practices in supervision of gerontological practice. The study compares participants' self-assessment of use of supervisory best practices before attending a 3-month workshop series and at two times following graduation. This article reports findings from the analysis of data provided by 114 out of 129 supervisors who completed the program. Participants increased the frequency of use of best practices at both three and 12 months after graduation. These increases were conceptually meaningful and statistically significant among participants who were low users of best practices prior to the program. SLA has led to significant adoption and maintenance of supervisory best practices among participating social work supervisors and especially among those who have not previously adopted routine use of best practices. The interactive small-group learning activities of SLA's educational model should be promoted and the curriculum of best practices should be further refined and tested as SLA is implemented in other communities.

Thirty-Year Survival After Cardiac Surgery in Children With Williams-Beuren Syndrome (from the Pediatric Cardiac Care Consortium Study).

Williams-Beuren syndrome (WBS) is a genetic condition frequently requiring interventions for associated congenital heart disease (CHD). Long-term survival data after cardiac interventions for children with WBS are sparse. This is a retrospective cohort study aiming to describe the 30-year survival outcomes of children with WBS after interventions for CHD using the Pediatric Cardiac Care Consortium (PCCC), a large North American-based registry of interventions for pediatric heart diseases, between 1982 and 2009. Outcomes were obtained from the PCCC and by linkage with the National Death Index through 2020. Survival of patients with WBS and their major subgroups was assessed by Kaplan-Meier survival curves and Cox regression. A total of 200 patients met the inclusion criteria of having their first intervention for CHD at a US PCCC center and age <21 years at time of intervention. The most common lesions were left heart obstructive lesions (LHOL), either in isolation (37%) or in combination with right heart obstructive lesions (RHOL) (49.0%), whereas isolated RHOL accounted for 11% of the total. The first procedure was surgery for 85.5% of the group, and the remainder underwent a transcatheter procedure. There were 5 in-hospital deaths (2.5%), and among survivors to hospital discharge, 164 had sufficient identifiers for National Death Index linkage. Over a median period of postdischarge follow-up of 23.7 years (interquartile range 18.7 to 27.3), 16 deaths occurred, with an overall 30-year survival rate of 90%. Survival rates ranged from 96.1% for isolated LHOL or RHOL to 83.4% for patients with combined disease (adjusted hazard ratio 4.7, 95% confidence intervals 1.35 to 16.59).

Surveillance, Diversity and Vegetative Compatibility Groups of Fusarium oxysporum f. sp. vasinfectum Collected in Cotton Fields in Australia (2017 to 2022)

Cotton (Gossypium hirsutum) is a billion-dollar crop in regional New South Wales (NSW) and Queensland, Australia. Fusarium wilt (FW) caused by Fusarium oxysporum f. sp. vasinfectum (Fov) is an economically important disease. Initial disease losses of up to 90% when the disease was first detected resulted in fields being taken out of cotton production. The disease is now well-managed due to the adoption of highly resistant varieties. However, annual disease surveys recently revealed that the disease dynamic has changed in the past few seasons. With relatively mild and wet weather conditions during the 2021/22 growing season, FW was detected in eight surveyed valleys in NSW and Queensland, with the disease incidence as high as 44.5% and 98.5% in individual fields in early and late seasons, respectively. Fov is genetically distinct and evolved from local Fusarium oxysporum strains. Additionally, the pathogen was reported to evolve rapidly under continuous cotton cropping pressure. However, our knowledge of the genetic composition of the prevailing population is limited. Sequences of the translation elongation factor alpha 1 (TEF1) revealed that 94% of Fusarium isolates recovered from FW-infected cotton were clustered together with known Australian Fov and relatively distant related to overseas Fov races. All these isolates, except for nine, were further confirmed positive with a specific marker based on the Secreted in Xylem 6 (SIX6) effector gene. Vegetative compatibility group (VCG) analyses of 166 arbitrarily selected isolates revealed a predominance of VCG01111. There was only one detection of VCG01112 in the Border Rivers valley where it was first described. In this study, the exotic Californian Fov race 4 strain was not detected using a specific marker based on the unique Tfo1 insertion in the phosphate (PHO) gene. This study indicated that the prevalence and abundance of Fov across NSW and Queensland in the past five seasons was probably independent of its genetic diversity.

A rehabilitation protocol for the use of a 3D-printed prosthetic hand in pediatrics: A case report.

INTRODUCTION AND PURPOSE: The purpose of this study was to evaluate the outcomes of utilizing a 3D prosthetic device with a home exercise program. This case study was intended to see if the application of a home exercise program utilizing a 3D printed prosthetic hand resulted in increased range of motion, strength, coordination, sensory integration, and perceived function of the upper extremity. STUDY DESIGN: Case Study METHODS: This study outlines one rehabilitation protocol for a 6-year-old boy with right congenital upper limb deficiency. A 4-week home rehabilitation protocol was utilized with a 3D printed prosthetic hand. Pre-assessment measurements were taken of range of motion, strength testing, BOT-2 coordination, and a sensory questionnaire. The home program included ROM exercises, body-powered use of the 3D printed device, strengthening without the device and sensory integration exercises. The frequency of the protocol was 3 times per week for 30 minutes with adult supervision. RESULTS: Improvements were seen in range of motion, strength, coordination, and sensory integration. Results demonstrated improved right upper extremity strength with all movements except radial deviation. Range of motion improved with passive and active wrist flexion, extension, and forearm pronation. Sensory integration questionnaires showed decreased sensory sensitivities. A structured home exercise program with and without a 3D printed hand improved upper extremity function in this population. DISCUSSION: Evaluating the outcomes of a home rehabilitation protocol for a child using a 3D printed hand was successful. The studies evidence will help guide treatment and clinical decision making for future studies.

Long-Term Outcomes of Cardiovascular Operations in Children With Connective Tissue Disorders.

Connective tissue disorders can be associated with significant cardiovascular morbidity needing cardiac surgery during childhood. In this retrospective study, we used the Pediatric Cardiac Care Consortium, a multicenter United States-based registry of pediatric cardiac interventions, to describe the long-term outcomes of patients who underwent their first surgery for connective tissue-related cardiovascular conditions aged <21 years. Between 1982 and 2003, a total of 103 patients were enrolled who underwent cardiac surgery for a connective tissue-related cardiovascular disorder, including 3 severe infantile cases operated on within the first year of life. Most patients underwent aortic site surgery (n = 85) as a composite graft (n = 50), valve-sparing (n = 33), or other aortic surgery (n = 2). The remaining patients underwent atrioventricular valve surgery (mitral 17, tricuspid 1). Of the 99 patients surviving to discharge, 80 (including the 3 infantile) had adequate identifiers for tracking long-term outcomes through 2019 through linkage with the National Death Index and the Organ Procurement. Over a median period of 19.5 years (interquartile range 16.0 to 23.1), 29 deaths and 1 transplant occurred in the noninfantile group, whereas all 3 infantile patients died before the age of 4 years. The postdischarge survival for the noninfantile group was 92.2%, 68.2%, and 56.7% at 10, 20, and 25 years, respectively. Cardiovascular-related pathology contributed to all deaths in the infantile and 89% (n = 27) of deaths for the noninfantile cases after hospital discharge. The significant late attrition from cardiovascular causes emphasizes the need for close monitoring and ongoing management in this population.

A single center observational study of the incidence, frequency and timing of critical care physiotherapy intervention during the COVID-19 pandemic.

Introduction: The recent COVID-19 pandemic saw many patients admitted to an intensive care setting and requiring mechanical ventilation. The NHS increased their critical care beds which included expanding the amount of staff. Physiotherapists were a key part of this and were required to complete numerous interventions within the COVID critical care setting throughout the pandemic. Our aim was to collect the incidence and frequency of physiotherapy interventions performed during the COVID-19 pandemic in a critical care setting. Method: Data was collected across all critical care beds at the Royal London Hospital for an eight-week period between March- April 2020. We retrospectively collected physiotherapy interventions for example, endotracheal suctioning and functional rehabilitation for every patient in the critical care setting. The Chelsea Critical Care Physical Assessment Tool (CPAx) scores were also obtained for patients on ACCU admission and discharge. Results: A total of 213 patients were included in the sample, 163 COVID-19 positive and 50 COVID-19 negative. Recorded sessions included secretion management (821), weaning (271), rescue therapy (82) and functional rehab (534) across the eight-week period. The mean CPAx score on admission to ACCU for the entire sample was 9/45 points. On discharge that score had improved to 25/45 points. Conclusion: This unique project has enabled us to report on the critical care physiotherapy interventions provided during the COVID 19 pandemic. This interesting data on frequency and timing of interventions may be useful to plan future relocation staffing plans and optimal allocation of care.

Transcatheter Recanalization of Atretic Pulmonary Veins in Infants and Children.

BACKGROUND: Pulmonary vein stenosis is a progressive disease associated with a high rate of mortality in children. If left untreated, myofibroblastic proliferation can lead to pulmonary vein atresia (PVA). In our experience, transcatheter recanalization has emerged as a favorable interventional option. We sought to determine the acute success rate of recanalization of atretic pulmonary veins and mid-term outcomes of individual veins after recanalization. METHODS: We reviewed all patients with PVA at our institution between 2008 and 2020 diagnosed by either catheterization or cardiac computed tomography. All veins with successful recanalization were reviewed and procedural success rate and patency rate were noted. Competing risk analysis was performed to demonstrate outcomes of individual atretic veins longitudinally. RESULTS: Between 2008 and 2020, our institution diagnosed and treated 131 patients with pulmonary vein stenosis. Of these, 61 patients developed atresia of at least one pulmonary vein. In total, there were 97 atretic pulmonary veins within this group. Successful recanalization was accomplished in 47/97 (48.5%) atretic veins. No atretic pulmonary veins were successfully recanalized before 2012. The majority of veins were recanalized between 2017 and 2020-39/56 (70%). The most common intervention after recanalization was drug-eluting stent placement. At 2-year follow-up 42.6% of recanalized veins (20.6% of all atretic veins) remained patent with a median of 4 reinterventions per person. CONCLUSIONS: Transcatheter recanalization of PVA can result in successful reestablishment of flow to affected pulmonary veins in many cases. Drug-eluting stent implantation was the most common intervention performed immediately post-recanalization. Vein patency was maintained in 42.6% of patients at 2-year follow-up from recanalization with appropriate surveillance and reintervention. Overall, only a small portion of atretic pulmonary veins underwent successful recanalization with maintained vessel patency at follow-up. Irrespective of successful recanalization, there was no detectable survival difference between the more recently treated PVA cohort and non-PVA cohort.

Association of the affordable care act Medicaid expansions with postpartum contraceptive use and early postpartum pregnancy.

OBJECTIVES: Before the Affordable Care Act (ACA), 55% of individuals giving birth with Medicaid lost insurance postpartum, potentially affecting their access to postpartum contraception. We evaluate the association of the ACA Medicaid expansions with postpartum contraceptive use and pregnancy at the time of the survey. METHODS: We used 2012-2019 Pregnancy Risk Assessment Monitoring System data to estimate difference-in-difference models for the association of Medicaid expansions with the use of postpartum contraception (mean: 4 months postpartum): any contraception, long-acting reversible contraception, or LARC (contraceptive implant and intrauterine device), short-acting (contraceptive pill, patch, and ring), permanent, or non-prescription methods (condoms, rhythm method, and withdrawal), and pregnancy at the time of the survey. We examine low-income respondents overall and stratified by race and ethnicity. RESULTS: We find that Medicaid expansion was associated with a 7.0 percentage point (95% CI: 3.0, 11.0) increase in postpartum LARC, a 3.1 percentage point (95% CI: -6.0, -0.2) decrease in short-acting contraception, and a 3.9 percentage point (95% CI: -6.2, -1.5) decrease in non-prescription contraceptive use overall. In stratified analyses, we find that increases in LARC use were concentrated among non-Hispanic White and Black respondents, with shifts in other postpartum contraceptives towards LARCs. Medicaid expansion was associated with a decrease in early postpartum pregnancy only among non-Hispanic Black respondents. CONCLUSIONS: Medicaid expansions led to shifts from methods with a lower upfront out-of-pocket cost for people without insurance towards methods with the higher upfront out-of-pocket cost for people without insurance. These changes suggest that Medicaid expansion improved postpartum contraceptive access. IMPLICATIONS: These findings indicate that postpartum uninsurance was a barrier to postpartum contraceptive access prior to Medicaid expansions under the Affordable Care Act. Medicaid expansions increased access to the full range of contraceptive methods.

Long-term outcomes after repair for anomalous right coronary artery from the pulmonary artery.

Anomalous right coronary artery from pulmonary artery (ARCAPA) is a rare congenital heart disease that can lead to abnormal coronary perfusion and a need for surgical repair. Here, we report the outcomes of patients who underwent ARCAPA surgery within the Pediatric Cardiac Care Consortium (PCCC), a North American registry of interventions for paediatric heart diseases. We queried the PCCC for patients undergoing surgical repair for ARCAPA at <18 years of age between 1982 and 2003. Outcomes were obtained from the PCCC and after linkage with the National Death Index (NDI) and the Organ Procurement and Transplantation Network (OPTN) through 2019. Twenty-four patients (males: 15) were identified having surgery for ARCAPA at a median age of 5.8 (IQR 2.7-10.3) years. Of them, 23 cases were considered "simple" (without major intracardiac disease) and one "complex" (co-existing with tetralogy of Fallot). Five patients presented with symptoms [chest pain (1), dyspnoea on exertion (2) or history of syncope (2)]; while the remaining 19 patients were referred for evaluation of either murmur or co-existing CHD. There was no in-hospital mortality after the surgical repair. Fourteen patients had sufficient identifiers for NDI/OPTN linkage; among them, only one death occurred from unrelated non-cardiac causes within a median period of 19.4 years of follow-up (IQR: 18-24.6). Outcomes were excellent after reimplantation up to 25 years later and further longitudinal monitoring is important to understand the interaction of pre-existing coronary pathology with the effects of ageing.

Long-term Outcomes of Children Operated on for Anomalous Left Coronary Artery From the Pulmonary Artery.

BACKGROUND: We examined the outcomes of children (<18 years) operated on for anomalous left coronary artery from the pulmonary artery (ALCAPA). METHODS: We linked patients undergoing ALCAPA repair between 1982 and 2003 in the Pediatric Cardiac Care Consortium with the National Death Index and the Organ Procurement and Transplantation Network to examine their outcomes through 2019. RESULTS: We identified 228 children (median age, 6.0 months) operated on for ALCAPA. At the time of repair, 38.6% had severe mitral regurgitation (MR), and 71.4% had severe left ventricular (LV) dysfunction. Repair included primarily coronary reimplantation in 173 and the Takeuchi procedure in 34; concurrently, 18 underwent mitral valve (MV) operation. In-hospital death occurred in 31 (13.6%) and was not associated with MR severity (P = .846); however, among patients with moderate or severe MR, risk of death was 28% lower when undergoing MV operation (P = .033). After adjustment for other risk factors, only infant operation reached statistical significance for in-hospital death (adjusted odds ratio, 12.99; 95% CI, 1.61-104.59; P = .016). Among those discharged alive with long-term data available (n = 155), the 30-year transplant-free survival reached 95.5% (95% CI, 92.3%-98.8%) and was not associated with the degree of preoperative MR or LV dysfunction. Coronary reimplantation was associated with better long-term survival compared with other surgical techniques (adjusted odds ratio, 0.11; 95% CI, 0.02-0.74; P = .023). CONCLUSIONS: Favorable long-term outcomes can be expected after coronary artery reimplantation for ALCAPA, even in patients with severe LV dysfunction at presentation. MV operation predicted decreased risk for in-hospital mortality in patients with moderate/severe MR, but MR severity predicted neither in-hospital nor longer-term outcomes.

Daily experiences of type 1 diabetes stress across adulthood.

AIMS: Daily diabetes stressful events take a toll on individuals with type 1 diabetes, and these experiences may look different across adulthood. The aims of the current study were to understand the nature of daily diabetes stress across adulthood and explore whether these experiences differed by age. METHODS: In this qualitative study, adults with T1D (N = 199, Mage  = 46.81 years) described the most stressful event related to their diabetes each evening as part of a 14-day diary. Using a grounded theory approach, diabetes stressful events were coded for where they occurred, the source of stress (i.e. interpersonal or not), and content (e.g. sleep; blood glucose checking; frustration). RESULTS: Participants reported having a diabetes-related stressful event on 58% (M = 0.58, SD = (0.25)) of days. Daily stressful events included issues of diabetes management, diabetes-related interference to or from other areas of life, and negative impact on psychological well-being, but rarely included a social component. Older adults were less likely to report having a diabetes-related stressful event, but were more likely to report that stressful events occurred at home, compared to younger adults. CONCLUSION: The lived experience of diabetes-related stress appears similar across ages, with individuals continuing to experience generally the same types of diabetes-related events in similar frequencies. Interventions to help improve diabetes outcomes or well-being may benefit from targeting the most commonly experienced areas of stress, which includes reducing the interference of daily activities to and by diabetes management.
