RESUMEN
OBJECTIVE: We sought to determine whether racial and ethnic disparities existed in inferior vena cava (IVC) filter (IVCF) placement rates among Black and Latino patients for the treatment of acute proximal lower extremity (LE) deep vein thrombosis (DVT) in the United States from 2016 to 2019. METHODS: We performed a retrospective review of National Inpatient Sample data to identify adult patients with a primary discharge diagnosis of acute proximal LE DVT from January 2016 to December 2019, including self-reported patient race and ethnicity. IVCF placement rates were identified using International Classification of Diseases, 10th revision, codes. Weighted multivariable logistic regression was used to compare IVCF use by race and ethnicity. The regression model was adjusted for patient demographics (ie, sex, primary payer, quartile classification of household income), hospital information (ie, region, location, teaching status, bed size), weekend admission, and clinical characteristics (ie, modified Charlson comorbidity index, hypertension, atrial fibrillation, diabetes mellitus type 2, congestive heart failure, dyslipidemia, coronary artery disease, smoking, obesity, alcohol abuse, chronic kidney disease, pulmonary embolism, malignancy, contraindications to anticoagulation, including other major bleeding). RESULTS: Of 134,499 acute proximal LE DVT patients, 18,909 (14.1%) received an IVCF. Of the patients who received an IVCF, 12,733 were White (67.3%), 3563 were Black (18.8%), and 1679 were Latino (8.9%). IVCF placement decreased for all patient groups between 2016 and 2019. After adjusting for the U.S. population distribution, the IVCF placement rates were 11 to 12/100,000 persons for Black patients, 7 to 8/100,000 persons for White patients, and 4 to 5/100,000 persons for Latino patients. The difference in IVCF placement rates was statistically significant between patient groups (Black patients vs White patients, P < .05; Black patients vs Latino patients, P < .05; Latino patients vs White patients, P < .05). CONCLUSIONS: This nationwide study showed that Black patients have higher IVCF placement rates compared with White and Latino patients. Given the known long-term complications and uncertain benefits of IVCFs, coupled with the 2010 U.S. Food and Drug Administration safety warning regarding adverse patient events for these devices, proactive measures should be taken to address this disparity among the Black patient population to promote health equity. Future work should assess whether clinician bias might be perpetuating this disparity.

Objectives: We sought to evaluate the efficacy and safety of refined balloon pulmonary angioplasty (BPA) in the treatment of patients with chronic thromboembolic pulmonary hypertension (CTEPH). Background: BPA is rapidly evolving therapeutic option for patients with nonsurgical CTEPH. There are few US studies that have reported on the outcomes of this novel therapeutic option. Methods: This is a retrospective study of CTEPH patients that underwent BPA at Temple University Hospital. The primary efficacy endpoint was the change in pulmonary vascular resistance (PVR) after BPA as compared to baseline and the primary safety endpoint was the rate of hemoptysis within 24 hours. Secondary endpoints included death, WHO functional class, and 6-minute walk distance (6MWD). We used logistic regression to evaluate factors associated with a hemodynamic and functional response. Results: A total of 211 BPA sessions were performed on 77 patients (average 2.7 ± 1.7 sessions/patient). After BPA the mean PVR improved by 26% (P<0.001) while the mean 6MWD improved by 71.7 meters (P <0.001) and WHO functional class improved by one functional class (P <0.001). Ten sessions (4.7%) were complicated by hemoptysis. The independent factors associated with a improved functional and hemodynamic response included the pre-procedural use of riociguat, reduce baseline PA compliance and > 3 BPA sessions per patient. Conclusion: This single center study from the US showed that BPA with refined techniques in patients with CTEPH was safe and was associated with significant improvements in pulmonary hemodynamics and functional capacity.
RESUMEN
Spontaneous coronary artery dissection (SCAD) is an important cause of acute myocardial infarction (AMI); however, the prevalence of SCAD and its predictors in AMI are unknown. We sought to derive and validate a simple score that can help predict SCAD in patients with AMI. We analyzed the Nationwide Readmissions Database and created a risk score for SCAD in patients with an index hospitalization for AMI. We used a multivariate logistic regression analysis to determine the independent predictors of SCAD, and each was assigned points proportional to its regression coefficient. Among 1,155,164 patients with AMI, 8,630 (0.75%) had SCAD. Based on the derivation cohort, the independent predictors of SCAD were fibromuscular dysplasia (odds ratio [OR] 67.0, 95% confidence interval [CI] 42.0 to 107.9, p <0.01), Marfan or Ehlers-Danlos syndrome (OR 4.7, 95% CI 1.7 to 12.5, p <0.01), polycystic ovarian syndrome (OR 5.4, 95% CI 3.0 to 9.8, p <0.01), female gender (OR 1.99, 95% CI 1.9 to 2.1, p <0.01), and aortic aneurysm (OR 1.41, 95% CI 1.1 to 1.7, p <0.01). The SCAD risk score included fibromuscular dysplasia (5 points), Marfan or Ehlers-Danlos syndrome (2 points), polycystic ovarian syndrome (2 points), female gender (1 point), and aortic aneurysm (1 point). The C-statistics of the score were 0.58 (derivation cohort) and 0.61 (validation cohort). In conclusion, the SCAD score is an easy bedside clinical tool that can help clinicians identify patients with AMI who are at risk for SCAD.

OBJECTIVE: Although it is traditionally considered ominous, the natural history of early proximal attachment site endoleaks (IA) after endovascular aneurysm repair (EVAR) is not well known. Our aim was to identify risk factors for persistent type IA endoleaks and to determine their effect on long-term outcomes after EVAR. METHODS: All patients who underwent infrarenal EVAR at a single institution between 1998 and 2015 were identified. Preoperative axial imaging and intraoperative arteriograms were reviewed, and those patients with a type IA endoleak were further studied. Aneurysm features were characterized by two reviewers and were studied for predictors of persistent endoleaks at the conclusion of the case. Patient records and the Social Security Death Index were used to record 1-year and overall survival. RESULTS: We identified 1484 EVARs, 122 (8%) of which were complicated by a type IA endoleak on arteriography after graft deployment, with a median follow-up of 4 years. The majority of patients underwent additional ballooning of the proximal site (52 [43%]) or placement of an aortic cuff (47 [39%]); 30 patients (25%) received a Palmaz stent, and four patients were treated with coils or anchors. At case end, only 43 (35%) of the type IA endoleaks remained; at 1 month, only 16 endoleaks persisted (13%), and only six persisted at 1 year (6%). In multivariable analysis, the only independent predictor of persistence of type IA endoleak at the conclusion of the case was the presence of extensive neck calcifications (odds ratio [OR], 9.9; 95% confidence interval [CI], 1.4-67.9; P = .02). Thirteen patients (11%) underwent reintervention for type IA endoleaks, with a time frame ranging from 3 days postoperatively to 11 years. There were three patients (2.4%) who experienced aneurysm rupture. Postoperative type IA endoleak was associated with lower survival at 1 year (79% vs 91%; relative risk, 2.5; 95% CI, 1.1-5.4; P = .02), but it did not affect long-term survival (log-rank, P = .45). Both an increase in aneurysm sac size and failure of the endoleak to resolve by case end were independent predictors of a need for reintervention (growth: OR, 8.3; 95% CI, 2.2-31.6; P < .01; persistent endoleak: OR, 7.6; 95% CI, 1.8-31.5; P < .01). A persistent type IA endoleak was not independently associated with an increase in sac size on surveillance imaging (P = .28). CONCLUSIONS: Aneurysm rupture secondary to persistent type IA endoleak is rare, and most will resolve within 1 year. Extensive neck calcification is the only independent predictor of persistent type IA endoleak, and an increase in sac size warrants reintervention. These data suggest that select early persistent type IA endoleaks can be safely observed.

Sunscreens have been widely used by the general public for their photoprotective properties, including prevention of photocarcinogenesis and photoaging and management of photodermatoses. It is important to emphasize to consumers the necessity of broad-spectrum protection, with coverage of both ultraviolet A (320-400 nm) and ultraviolet B (290-320 nm) radiation. This review discusses the benefits of sunscreen, different ultraviolet filters, sunscreen regulations and controversies, the importance of broad-spectrum protection, issues of photostability and formulation, and patient education and compliance.
