Racial and ethnic representation in peripheral artery disease randomized clinical trials.

Clinical trial enrollment provides various benefits to study participants including early access to novel therapies that may potentially alter the trajectory of disease states. Trial sponsors benefit from enrolling demographically diverse trial participants enabling the trial outcomes to be generalizable to a larger proportion of the community at large. Despite these and other well-documented benefits, clinical trial enrollment for Black and Hispanic Americans as well as women continues to be low. Specific disease states such as peripheral artery disease (PAD) have a higher prevalence and clinical outcomes are relatively worse in Black Americans compared with non-Hispanic white Americans. The recruitment process for PAD clinical trials can be costly and challenging and usually comes at the expense of representation. Participant willingness and trust, engagement, and socioeconomic status play essential roles in the representation of under-represented minority (URM) groups. Despite the contrary belief, URM groups such as Blacks and Hispanics are just as willing to participate in a clinical trial as non-Hispanic Whites. However, financial burdens, cultural barriers, and inadequate health literacy and education may impede URMs' access to clinical trials and medical care. Clinical trials' enrollment sites often pose transportation barriers and challenges that negatively impact creating a diverse study population. Lack of diversity among a trial population can stem from the stakeholder level, where corporate sponsors of academic readers do not consider diversity in clinical trials a priority due to false cost-benefit assumptions. The funding source may also impact the racial reporting or the results of a given trial. Industry-based trials have always been criticized for over-representing non-Hispanic White populations, driven by the desire to reach high completion rates with minimum financial burdens. Real efforts are warranted to ensure adequate minorities' representation in the PAD clinical trials and to the process toward the ultimate goal of developing more durable and effective PAD treatments that fit the needs of real-world populations.

No difference in midterm outcomes and complication rate between retroperitoneal and transperitoneal open aortic aneurysm repair in females.

OBJECTIVES: Abdominal Aortic Aneurysms (AAA) in females are less prevalent, have higher expansion rates and experience rupture at smaller diameters than in males. Studies have compared outcomes of the retroperitoneal (RP) and transperitoneal (TP) approach in open aortic aneurysm repair (OAR) with conflicting results. No study to date has compared the two approaches solely in females. In this study we compare midterm outcomes of the RP and TP approach in females undergoing OAR. METHODS: Single-center, retrospective review of all females undergoing OAR from 2010 to 2021. Patients undergoing elective, symptomatic and ruptured OAR were included. The cohort was stratified by surgical approach RP versus TP and midterm outcomes were compared amongst the groups. Outcomes included mortality, graft related, and non-graft related complications. RESULTS: A total of 244 patients (RP n = 133; TP n = 111) were identified. Follow-up period was 28 ± 30.7 months. Baseline perioperative characteristics were similar except that more people in the RP group had ejection fraction ((EF) > 50% (82% vs 68%), p = .037). Patients who underwent RP repair had longer visceral/renal ischemia time (p = .01), larger graft diameter (18 vs 16 mm; p = <0.001), were more likely to have a suprarenal clamp placed(70.5 vs 48.2; p < .001), and had decreased autotransfusion volume (611 vs 861 mL; p < .01) compared to those who underwent TP repair. Number of deaths was higher in the TP group during study follow-up period (36.4 vs 23.8; p = .035), but the difference of the time to event analysis was not significant. There was no difference in all-cause survival at 36 months between RP and TP (77.8 vs 76.8; p = .045). Overall midterm complications were 9.5% in both groups. Any graft related complication was 1.8% in TP versus 3% RP (p = .69). In a multivariable model, after adjusting for age, urgency, smoking, prior aneurysm repair, and ASA level, the hazard ratio decreases with the RP approach, however this did not reach significance (p = .052). CONCLUSION: In a 12-year period of OAR in females, TP and RP results were comparable at midterm analysis. The RP approach appeared to be used more often for OAR requiring suprarenal clamping. Although the TP group had increased mortality, the difference of the time to event analysis was not significant. Midterm postoperative complications in both groups were low. This suggests that both approaches are safe in the female population and decision should be driven by anatomy and surgeon's preference.

Bariatric and Metabolic Surgery in the Adult Population: What a Primary Care Provider Needs to Know.

Obesity is a significant public health concern worldwide and a leading cause of preventable death and morbidity, but the management of this condition remains a challenge. Metabolic and bariatric surgery (MBS) is safe and currently has the most consistent and robust data among anti-obesity interventions for ameliorating obesity and its associated complications. Despite the benefits and safety of MBS, it is significantly underused. There are several proposed reasons for this underuse, one of which is a knowledge gap among primary care physicians, contributing to low referral rates. The purpose of this review is to summarize key points of the 2022 American Society for Metabolic and Bariatric Surgery/International Federation for the Surgery of Obesity and Metabolic Disorders guidelines regarding MBS, as well as to discuss indications, benefits and risks, most common types of MBS, and barriers to access, thereby increasing awareness of MBS among primary care physicians. This narrative review was based on articles found by searching PubMed from its inception until April 2024 for the terms sleeve gastrectomy, gastric bypass, and metabolic and bariatric surgery. Our search was confined to English-language publications, with emphasis placed on evidence derived from systematic literature reviews, meta-analyses, and randomized clinical trials whenever available.

Effects of Sociodemographic Factors on Access to and Outcomes in Congenital Heart Disease in the United States.

Congenital heart defects (CHDs) are complex conditions affecting the heart and/or great vessels that are present at birth. These defects occur in approximately 9 in every 1000 live births. From diagnosis to intervention, care has dramatically improved over the last several decades. Patients with CHDs are now living well into adulthood. However, there are factors that have been associated with poor outcomes across the lifespan of these patients. These factors include sociodemographic and socioeconomic positions. This commentary examined the disparities and solutions within the evolution of CHD care in the United States.

Predictors of spontaneous pregnancy loss in single ventricle physiology.

BACKGROUND: Pregnant patients with single ventricle (SV) physiology carry a high risk of spontaneous pregnancy loss (SPL), yet the clinical factors contributing to this risk are not well defined. METHODS: Single-centre retrospective study of pregnant patients with SV physiology seen in cardio-obstetrics clinic over the past 20 years with chart review of their obstetric history. Patients without a known pregnancy outcome were excluded. Univariable Bayesian panel-data random effects logit was used to model the risk of SPL. RESULTS: The study included 20 patients with 44 pregnancies, 20 live births, 21 SPL and 3 elective abortions. All had Fontan palliation except for two with Waterston and Glenn shunts. 10 (50%) had a single right ventricle (RV). 14 (70%) had moderate or severe atrioventricular valve regurgitation (AVVR). Atrial arrhythmias were present in 16 (80%), Fontan-associated liver disease (FALD) in 15 (75%) and FALD stage 4 in 9 (45%). 12 (60%) were on anticoagulation. Average first-trimester oxygen saturation was 93.8% for live births and 90.8% for SPL. The following factors were associated with higher odds of SPL: RV morphology (OR 1.72 (95% credible interval (CrI) 1.0008-2.70)), moderate or severe AVVR (OR 1.64 (95% CrI 1.003-2.71)) and reduced first-trimester oxygen saturation (OR 1.83 (95% CrI 1.03-2.71) for each per cent decrease in O2 saturation. CONCLUSION: Pregnant patients with SV physiology, particularly those with RV morphology, moderate or severe AVVR, and lower first-trimester oxygen saturations, have a higher risk of SPL. Identifying these clinical risk factors can guide preconception counselling by the cardio-obstetrics team.

Transcatheter Aortic Valve Replacement in Congenital Heart Disease.

Transcatheter aortic valve replacement is not widely used in patients with congenital heart disease. We describe our single-center experience of transcatheter aortic valve replacement in congenital heart disease, demonstrating short-term feasibility and safety, role in lifetime management of congenital aortic valve disease, and use as a bridge to recovery, future surgery, or transplantation.

Can perioperative electroencephalogram and adverse hemodynamic events predict neurodevelopmental outcomes in infants with congenital heart disease?

OBJECTIVE: The study objective was to characterize preoperative and postoperative continuous electroencephalogram metrics and hemodynamic adverse events as predictors of neurodevelopment in congenital heart disease infants undergoing cardiac surgery. METHODS: From 2010 to 2021, 320 infants underwent congenital heart disease surgery at our institution, of whom 217 had perioperative continuous electroencephalogram monitoring and were included in our study. Neurodevelopment was assessed in 76 patients by the Bayley Scales of Infant and Toddler Development, 3rd edition, consisting of cognitive, communication, and motor scaled scores. Patient and procedural factors, including hemodynamic adverse events, were included by means of the likelihood of covariate selection in our predictive model. Median (25th, 75th percentile) follow-up was 1.03 (0.09, 3.44) years with 3 (1, 6) Bayley Scales of Infant and Toddler Development, 3rd Edition evaluations per patient. RESULTS: Median age at index surgery was 7 (4, 23) days, and 81 (37%) were female. Epileptiform discharges, encephalopathy, and abnormality (lethargy and coma) were more prevalent on postoperative continuous electroencephalograms, compared with preoperative continuous electroencephalograms (P < .005). In 76 patients with Bayley Scales of Infant and Toddler Development, 3rd edition evaluations, patients with diffuse abnormality (P = .009), waveform discontinuity (P = .007), and lack of continuity (P = .037) on preoperative continuous electroencephalogram had lower cognitive scores. Patients with synchrony (P < .005) on preoperative and waveform continuity (P = .009) on postoperative continuous electroencephalogram had higher fine motor scores. Patients with postoperative adverse events had lower cognitive (P < .005) and gross motor scores (P < .005). CONCLUSIONS: Phenotypic patterns of perioperative continuous electroencephalogram metrics are associated with late-term neurologic injury in infants with congenital heart disease requiring surgery. Continuous electroencephalogram metrics can be integrated with hemodynamic adverse events in a predictive algorithm for neurologic impairment.

Determining the Minimum Clinically Important Difference for the European Hernia Society Quality of Life Instrument in Inguinal Hernia Repair Patients.

BACKGROUND: Patient-reported outcomes in clinical research allow for a more comprehensive and meaningful assessment of interventions but are subjective and difficult to interpret. European Registry for Abdominal Wall Hernias-Quality of Life (EuraHS-QoL) is a tool designed to assess perioperative quality of life for patients undergoing inguinal hernia repair, one of the most performed operations worldwide. Defining the minimum clinically important difference (MCID) for EuraHS-QoL tool can help standardize its interpretation for research purposes and facilitate improved shared decision making in clinical settings. STUDY DESIGN: A combination of 3 approaches for estimating MCIDs was used in this study. First, 2 distribution-based approaches were used that based estimates on statistical parameters of the data. The SEM provided a minimum value for the MCID, and one-half of the SD provided a point estimate of the MCID. Second, anchor-based approaches integrated patient perceptions of their overall well-being before and after surgery to provide benchmarks for the MCID. Last, iterative surveys of expert hernia surgeons were used to yield the final MCIDs for each domain and the composite EuraHS-QoL score. RESULTS: The overall range of EuraHS-QoL is 0 to 90, with subdomain ranges of 0 to 30 for the pain domain, 0 to 40 for the restriction of activities domain, and 0 to 20 for the cosmesis domain, with higher scores representing worse outcomes. The overall MCID for EuraHS-QoL is 10. Domain-specific MCIDs are 3 for the pain domain, 5 for the restriction of activities domain, and 2 for the cosmesis domain. CONCLUSIONS: In this study, we define overall and domain-specific MCIDs for the EuraHS-QoL instrument using statistical methods, patient-based methods, and clinical expertise, providing estimates that are both statistically and clinically significant.
