Health disparities in ocular oncology.

Social determinants of health (SDH) play a crucial role in shaping health outcomes. Few studies have explored the impact of SDH in ocular oncology, looking at differences in disease presentation, treatment choices, and outcomes based on race, ethnicity, socioeconomic status (SES), and insurance status. Retinoblastoma exhibits disparities in survival, with lower-income countries experiencing substantially lower rates compared to high-income countries. In the U.S., racial and SES disparities exist, impacting treatment choices and outcomes in children with retinoblastoma. Disparities in treatment modalities based on race and SES have been reported in uveal melanoma, with non-White and economically disadvantaged patients more likely to undergo primary enucleation. Ocular surface squamous neoplasia (OSSN) exhibits racial and socioeconomic disparities in treatment outcomes. Black patients with OSSN face higher mortality, independent of tumor size, eye laterality, or tumor behavior. Given the rarity, there is no data on disparities in vitreoretinal lymphoma management. When using primary central nervous system lymphoma as a surrogate, management and survival outcomes vary based on factors such as race, socioeconomic status, and insurance status. This article aims to review current literature on disparities in ocular oncology, highlighting the need for granular data to better understand existing gaps in care within ocular oncology.

Clinical Profile and Prognosis of Patients with Left-Sided Infective Endocarditis with Surgical Indication Who Are Not Operated.

Approximately a quarter of patients with infective endocarditis (IE) who have surgical indication only receive antibiotic treatment. Their short-term prognosis is dismal. We aimed to describe the characteristics of this group of patients to evaluate the mortality according to the cause of rejection and type of surgical indication and to analyze their prognostic factors of mortality. From 2005 to 2022, 1105 patients with definite left-sided IE were consecutively attended in three tertiary hospitals. Of them, 912 (82.5%) had formal surgical indication according to the most recent European Guidelines available in each period of the study and 303 (33%) only received medical treatment. These were older, had more comorbidities and higher in-hospital (46% vs. 24%; p < 0.001) and one year mortality (57.1% vs. 27.6%; p < 0.001) than operated patients. The main reason for surgical rejection was high surgical risk (57.1%) and the highest mortality when the cause were severe neurological conditions (76%). When the endocarditis team took the decision not to operate (25.5% of the patients), in-hospital (7%) and one-year mortality (17%) were low. In-hospital mortality associated with each surgical indication was 67% in heart failure, 53% in uncontrolled infection and 45% in prevention of embolisms (p < 0.001). Heart failure (OR: 2.26 CI95%: 1.29-3.96; p = 0.005), Staphylococcus aureus (OR: 3.17; CI95%: 1.72-5.86; p < 0.001) and persistent infection (OR: 5.07 CI95%: 2.85-9.03) are the independent risk factors of in-hospital mortality. One third of the patients with left-sided IE and formal surgical indication are rejected for surgery. In-hospital mortality is very high, especially when heart failure is the indication for surgery and when severe neurological conditions the reason for rejection. Short term prognosis of patients rejected by a specialized endocarditis team is favorable.

Urban environment and health: a cross-sectional multiregional project based on population health surveys in Spain (DAS-EP project) - study protocol.

INTRODUCTION: The European Environment Agency estimates that 75% of the European population lives in cities. Despite the many advantages of city life, the risks and challenges to health arising from urbanisation need to be addressed in order to tackle the growing burden of disease and health inequalities in cities. This study, Urban environment and health: a cross-sectional multiregional project based on population health surveys in Spain (DAS-EP project), aims to investigate the complex association between the urban environmental exposures (UrbEEs) and health. METHODS AND ANALYSIS: DAS-EP is a Spanish multiregional cross-sectional project that combines population health surveys (PHS) and geographical information systems (GIS) allowing to collect rich individual-level data from 17 000 adult citizens participating in the PHS conducted in the autonomous regions of the Basque Country, Andalusia, and the Valencian Community, and the city of Barcelona in the years 2021-2023. This study focuses on the population living in cities or metropolitan areas with more than 100 000 inhabitants. UrbEEs are described by objective estimates at participants' home addresses by GIS, and subjective indicators present in PHS. The health outcomes included in the PHS and selected for this study are self-perceived health (general and mental), prevalence of chronic mental disorders, health-related quality of life, consumption of medication for common mental disorders and sleep quality. We aim to further understand the direct and indirect effects between UrbEEs and health, as well as to estimate the impact at the population level, taking respondents' sociodemographic and socioeconomic characteristics, and lifestyle into consideration. ETHICS AND DISSEMINATION: The study was approved by the regional Research Ethics Committee of the Basque Country (Ethics Committee for Research Involving Medicinal Products in the Basque Country; PI2022138), Andalusia (Biomedical Research Ethics Committee of the Province of Granada; 2078-N-22), Barcelona (CEIC-PSMar; 2022/10667) and the Valencian Community (Ethics Committee for Clinical Research of the Directorate General of Public Health and Center for Advanced Research in Public Health; 20221125/04). The results will be communicated to the general population, health professionals, and institutions through conferences, reports and scientific articles.

Soluble ST2, BCN-Bio-HF calculator and MAGGIC-HF score in long-term risk prediction after an urgent visit for heart failure.

Soluble ST2 (sST2) is the expression of a pathogenic process related to adverse remodeling that ultimately leads to increased mortality in heart failure (HF). Risk score models provide a comprehensive approach for mortality prediction, beyond the use of biomarkers alone. The objective was to determine the additional value of sST2 and two well-validated contemporary risk scores, BCN-Bio-HF and MAGGIC-HF, in predicting mortality and readmission in the acute setting. This prospective study included 129 patients (mean age 75 ± 9 years; 52% males) after an urgent HF visit. Baseline sST2 levels were measured and the two risk scores were calculated. The primary endpoint was all-cause mortality, and the secondary endpoint was HF readmissions. The follow-up period was 3.6 ± 1.9 years. Patients who died (46%) had higher sST2 concentrations (80.5 vs. 42.7 ng/ml; p < 0.001). The BCN-Bio-HF calculator with sST2 demonstrated the best discriminative ability for mortality prediction (area under the ROC curve: 0.792; p < 0.001). In multivariate analysis for each risk score, the MAGGIC-HF score retained its predictive value only in the model without sST2 (3-year risk: HR = 1.036; 95% CI 1.019-1.054; p < 0.001). However, the BCN-Bio-HF score maintained its prognostic value with sST2 (HR = 1.032; 95%CI 1.020-1.044; p < 0.001), as well as without sST2 (HR = 1.035; 95% CI 1.021-1.049; p < 0.001). sST2 was not associated with readmission, and only the BCN-Bio-HF risk of HF hospitalization showed independent predictive value (OR = 1.040; 95% CI 1.005-1.076; p = 0.023). For predicting long-term mortality in HF in the emergency department, the BCN-Bio-HF calculator with sST2 demonstrated superior discrimination and allows estimation of the risk of HF hospitalizations.

Bicaval TricValve Implantation in Patients With Severe Symptomatic Tricuspid Regurgitation: 1-Year Follow-Up Outcomes.

BACKGROUND: Several orthotopic transcatheter strategies have been developed to treat severe tricuspid regurgitation (TR); however, many patients are deemed unsuitable. Caval valve implantation with the TricValve system addresses this unmet need. OBJECTIVES: This study sought to determine the impact of TricValve on systemic congestion and quality of life (QOL) at 1 year. METHODS: The TRICUS (Safety and Efficacy of the TricValve® Transcatheter Bicaval Valves System in the Superior and Inferior Vena Cava in Patients With Severe Tricuspid Regurgitation) and TRICUS EURO studies were prospective, nonblinded, nonrandomized, single-arm trials representing the early-in-man experience of the TricValve system in NYHA functional class III or IV severe TR patients, optimally medicated and ineligible for open heart surgery, with significant caval backflow. The primary endpoint was QOL metrics and functional status. The 1-year results of the combined cohort are described here. RESULTS: Forty-four patients were included. Mean age was 76.2 ± 7.5 years, 81.0% were women, and the TRISCORE (risk score model for isolated tricuspid valve surgery) was 5.3 ± 1.3. Clinical improvement at 1 year was achieved in 42 (95.5%) patients, measured by (at least 1 of) an increase in ≥15 points from baseline in 12-item Kansas City Cardiomyopathy Questionnaire score, improvement to NYHA functional class to I or II, or an increase ≥40 m in the 6-minute walk test. There were 3 (6.8%) deaths at 1-year follow-up (1 cardiovascular), and the heart failure rehospitalization rate was 29.5%. Stent fracture, conduction system disturbances, or clinically significant leaflet thrombosis were not detected. Abolished hepatic vein backflow was achieved and persisted in 63.8% of the patients, contributing towards a reduction in congestive symptoms, N-terminal pro-B-type natriuretic peptide levels (P = 0.032), and diuretic treatment. CONCLUSIONS: Caval valve implantation with the TricValve system associated with meaningful 1-year clinical improvements in terms of QOL along with relatively low mortality rates.

Clinical outcomes of TAVI with the Myval balloon-expandable valve for non-calcified aortic regurgitation.

BACKGROUND: Transcatheter aortic valve replacement (TAVR) in non-calcified aortic regurgitation (NCAR) is an off-label procedure. The balloon-expandable Myval includes extra-large sizes (30.5 mm and 32 mm) of interest in this setting. AIMS: We aimed to evaluate the safety and feasibility of Myval in NCAR. METHODS: This was an international, multicentre, observational study that enrolled all consecutive patients with symptomatic severe NCAR undergoing TAVR with the Myval device. The images were centrally analysed. RESULTS: A total of 113 patients were recruited, 64.6% were men, the mean age was 78.4±7.5 years, and the Society of Thoracic Surgeons score was 2.7±1.7%. Aortic root dilatation was present in 59.3% of patients, 7.1% were bicuspid, and the mean annular area was 638.6±106.0 mm2. The annular area was beyond the recommended range for extra-large sizes in 2.6% of cases, and additional volume was added in 92% (median 4 cc, up to 9 cc). The extra-large sizes were used in 95 patients (84.1%), and the mean oversizing was 17.9±11.0%. The technical success rate was 94.7%; the rate of residual ≥moderate aortic regurgitation was 8.9%, and the pacemaker rate was 22.2%. There were no cases of annular rupture, cardiac tamponade, or aortic dissection, but in 4 patients (3.5%) valve embolisation occurred (1 antegrade and 3 ventricular), all in cases with a tapered left ventricle outflow tract (p=0.007). Thirty-day and 1-year mortality were 5.3% and 9.7%, respectively. Technical success was associated with better survival (97.1% vs 72.7%; p=0.012), and valve embolisation was the main determinant of mortality (p=0.047). CONCLUSIONS: Myval is a feasible and safe option for selected non-operable patients with NCAR and demonstrated good midterm outcomes and lack of impact of oversizing on device durability.

Magnetic resonance analysis of ventricular volumes in bicuspid and trileaflet aortic regurgitation.

OBJECTIVE: To identify differences in left ventricular (LV) remodelling between patients with bicuspid aortic valve (BAV) and trileaflet aortic valve (TAV) with chronic aortic regurgitation (AR). METHODS: Retrospective cohort study of 210 consecutive patients undergoing cardiac magnetic resonance for AR evaluation. We divided the study population according to valvular morphology. Independent predictors of LV enlargement AR were evaluated. RESULTS: There were 110 patients with BAV and 100 patients with TAV. Patients with BAV were younger (mean age BAV vs TAV: 41±16 years vs 67±11 years; p<0.01), mostly male (% male BAV vs TAV: 84.5% vs 65%, p=0.01) and presented milder degrees of AR (median regurgitant fraction BAV vs TAV: 14 (6-28)% vs 22 (12-35)%, p=0.002). Both groups presented similar indexed LV volumes and ejection fraction. According to the degree of AR, at mild AR, patients with BAV presented larger LV volumes (BAV vs TAV: indexed end diastolic left ventricular volumes (iEDV): 96.5±19.7 vs 82.1±19.3 mL, p<0.01; indexed end systolic left ventricular volumes (iESV): 39.4±10.3 mL vs 33.2±10.5 mL, p=0.01). These differences disappeared at higher degrees of AR. Independent predictors of LV enlargement were regurgitant fraction (EDV: OR 1.118 (1.081-1.156), p<0.001; ESV: OR 1.067 (1.042-1.092), p<0.001), age (EDV: OR 0.940 (0.917-0.964), p<0.001, ESV: OR 0.962 (0.945-0.979), p<0.001) and weight (EDV: OR 1.054 (1.025-1.083), p<0.001). CONCLUSIONS: In chronic AR, LV enlargement is an early finding. LV volumes display a direct correlation with regurgitant fraction and an inverse association with age. Patients with BAV present larger ventricular volumes, especially at mild AR. However, these differences are attributable to demographic disparities; valve type is not independently associated with LV size.

Latest-iteration balloon- and self-expandable transcatheter valves for severe bicuspid aortic stenosis: the TRITON study.

INTRODUCTION AND OBJECTIVES: No comparisons have been published yet regarding the newest iteration of balloon- and self-expandable transcatheter heart valves for the treatment of bicuspid aortic valve (BAV) stenosis. METHODS: Multicenter registry of consecutive patients with severe BAV stenosis treated with balloon-expandable transcatheter heart valves (Myval and SAPIEN 3 Ultra, S3U) or self-expanding Evolut PRO+(EP+). TriMatch analysis was carried out to minimize the impact of baseline differences. The primary endpoint of the study was 30-day device success, and the secondary endpoints were the composite and individual components of early safety at 30 days. RESULTS: A total of 360 patients (age 76.6±7.6 years, 71.9% males) were included: 122 Myval (33.9%), 129 S3U (35.8%), and 109 EP+(30.3%). The mean STS score was 3.6±1.9%. There were no cases of coronary artery occlusion, annulus rupture, aortic dissection, or procedural death. The primary endpoint of device success at 30 days was significantly higher in the Myval group (Myval: 100%; S3U: 87.5%; and EP+: 81.3%), mainly due to higher residual aortic gradients with S3U and greater≥moderate aortic regurgitation (AR) with EP+. No significant differences were found in the unadjusted rate of pacemaker implantation. CONCLUSIONS: In patients with BAV stenosis deemed unsuitable for surgery, Myval, S3U and EP+showed similar safety but balloon-expandable Myval had better gradients than S3U, and both balloon-expandable devices had lower residual AR than EP+, suggesting that, taking into consideration the patient-specific risks, any of these devices can be selected with optimal outcomes.

Electrically evoked stapedial reflex threshold and behavioral method usefulness in the cochlear implant programming in pediatric population.

OBJETIVE: To determine the utility of the electrically evoked stapedial reflex test (ESRT) and behavioral method in the CIs programming as an objective method to identify MCL levels in the CIs programming in pediatric patients. METHOD: Cross-sectional cohort study that included 20 pediatric patients with postlingual deafness and CI unilateral. They were performed clinical history, tympanometry, ESRT and by free field audiometry, before and after programming modifications according to MCL levels obtained by ESRT were performed. ESRT threshold was assessed with individual 300 ms stimuli on the 12 electrodes and recorded through manual decay. Likewise, the maximum comfort threshold (MCL) of each electrode was obtained through a behavioral analysis. RESULTS: No significant differences were found between the ESRT and behavioral method in MCLs levels in each of the electrodes evaluated. In addition, the correlation coefficients were significant and located in a range of 0.55-0.81, higher in electrodes 7, 8, and 9 (r = 0.77, 0.76, and 0.81, respectively). However, the median hearing threshold established by the ESRT was significantly lower compared to the behavioral threshold (36.0 vs. 47.0 dB, p < 0.0001), regardless of age (p = 0.249) or the etiology of hearing loss (p = 0.292). The difference between the tests was in the number of times to do it, the ESRT was done once and the behavioral on average 4 ± 1 times. CONCLUSION: Similar MCL thresholds were obtained in both ESRT and behavioral test, establishing that both methods are reliable for use in pediatric patients; however, ESRT allows shortening the time to achieve normal hearing and language acquisition thresholds in a more optimal time.

Treatment of COVID-19 with convalescent plasma in patients with humoral immunodeficiency - Three consecutive cases and review of the literature.

Patients lacking humoral response have been suggested to develop a less severe COVID-19, but there are some reports with a prolonged, relapsing or deadly course. From April 2020, there is growing evidence on the benefits of COVID-19 convalescent plasma (CCP) for patients with humoral immunodeficiency. Most of them had a congenital primary immunodeficiency or were on treatment with anti CD20 antibodies. We report on three patients treated in our hospital and review thirty-one more cases described in the literature. All patients but three resolved clinical picture with CCP. A dose from 200 to 800ml was enough in most cases. Antibody levels after transfusion were negative or low, suggesting consumption of them in SARS-CoV-2 neutralization. These patients have a protracted clinical course shortened after CCP. CCP could be helpful for patients with humoral immunodeficiency. It avoid relapses and chronification. CCP should be transfused as early as possible in patients with COVID-19 and humoral immunodeficiency.

Se ha sugerido que los pacientes carentes de respuesta inmune humoral desarrollan una forma menos severa de COVID-19, pero existen algunos casos de curso prolongado, recurrente o incluso mortal. Desde abril de 2020 existen evidencias de los beneficios del plasma de convalecientes de COVID-19 (PCC) en los pacientes con inmunodeficiencia humoral. La mayoría tienen una inmunodeficiencia congénita primaria o están recibiendo tratamiento con anticuerpos anti-CD20. Describimos tres pacientes con inmunodeficiencia humoral y COVID-19 tratados con PCC en nuestro centro y revisamos los 31 casos más descritos en la literatura. Todos resolvieron el cuadro clínico con PCC, salvo tres. Una dosis de 200-800 mL fue suficiente en la mayoría de los casos. Los niveles de anticuerpos tras la transfusión fueron negativos o bajos, sugiriendo el consumo de los mismos en la neutralización del SARS-CoV-2. Estos pacientes tienen un curso clínico prolongado que se acorta tras la administración del PCC. El PCC podría ser de utilidad en los pacientes con inmunodeficiencia humoral. Evita las recaídas y la cronificación de la COVID-19. El PCC debería transfundirse lo antes posible en los pacientes con COVID-19 e inmunodeficiencia humoral.(AU)

Myval versus alternative balloon- and self-expandable transcatheter heart valves: A central core lab analysis of conduction disturbances.

BACKGROUND: Several studies have compared surface electrocardiographic changes following different self-expandable (SE) (Evolut (Medtronic, USA); Acurate (Boston Scientific, USA); Portico (Abbott, USA); and Allegra (NVT, Germany)) and balloon-expandable (BE) Sapien-3 (Edwards Lifesciences, USA) transcatheter heart valves. We aimed to compare these prosthesis with the novel Myval BE prosthesis (Meril Life, India). METHODS: Academic European registry of consecutive patients with severe aortic stenosis who received any of the 6 aforementioned valves. Baseline, post-procedural, and discharge 12­leads electrocardiograms (ECG) were centrally analyzed and compared. RESULTS: A total of 1131 patients were included: 135 Myval (11.9%), 290 Sapien-3 (25.6%), 298 Evolut (26.3%), 180 Acurate (15.9%), 125 Portico (11.1%), and 103 Allegra (9.1%). There were no baseline differences in intraventricular conduction disturbances rate. Compared to the novel BE Myval, there were similar procedural and in-hospital outcomes. Similar rates of early new permanent pacemaker implant (PPI) were observed amongst Myval (7.4%), Sapien-3 (13.4%), and Acurate (9.1%), but Evolut, Portico, and Allegra presented significantly higher rates (18.5%, p = 0.003; 29.5% p < 0.001 and 22%, p = 0.001, respectively). Central analysis of ECGs, unraveled significant prolongation of the PR segment with Evolut, Portico and Allegra whereas Evolut, Acurate, and Portico showed significant QRS widening compared to Myval. However, at discharge no differences in PR segment duration were observed while, Evolut, and Portico- but not Acurate, Allegra or Sapien-3 - still presented significant widening of QRS segment compared to Myval. CONCLUSIONS: After blinded central ECG analysis, the novel Myval balloon-expandable prosthesis was associated with a low rate of early conduction disturbances.

Next-generation balloon-expandable Myval transcatheter heart valve in low-risk aortic stenosis patients.

OBJECTIVES: We aimed to describe hemodynamic performance and clinical outcomes at 30-day follow-up of the balloon-expandable (BE) Myval transcatheter heart valve (THV) in low-risk patients. BACKGROUND: The results of the next-generation BE Myval THV in low-risk aortic stenosis (AS) patients are still unknown. METHODS: Retrospective registry performed in nine European centers including patients with low predicted operative mortality risk according to Society of thoracic surgeons (STS) and European system for cardiac operative risk evaluation (EuroSCORE-II) scores. RESULTS: Between September 2019 and February 2021, a total of 100 patients (51% males, mean age 80 ± 6.5 years) were included. Mean STS score and EuroSCORE-II were 2.4 ± 0.8% and 2.2 ± 0.7%, respectively. Intermediate sizes were used in 39% (21.5 mm: 8%, 24.5 mm: 15%, 27.5 mm: 15%). There were no cases of valve embolization, coronary artery occlusion, annulus rupture, or procedural death. A definitive pacemaker implantation was needed in eight patients (8%). At 30-day follow-up aortic valve area (0.7 ± 0.2 vs. 2.1 ± 0.6 cm2 ) and mean aortic valve gradient (43.4 ± 11.1 vs. 9.0 ± 3.7 mmHg) improved significantly (p < 0.001). Moderate aortic regurgitation occurred in 4%. Endpoints of early safety and clinical efficacy were 3 and 1%, respectively. CONCLUSIONS: Hemodynamic performance and 30-day clinical outcomes of the BE Myval THV in low-risk AS patients were favorable. Longer-term follow-up is warranted.
