Outcomes of Drug-Eluting Balloons for In-Stent Restenosis: Large Cohort Analysis and Single-Center Clinical Experience.

BACKGROUND: The use of drug-eluting balloons (DEBs) remains clinically relevant in the contemporary era of drug-eluting stent percutaneous coronary interventions (DES-PCI), especially in the setting of in-stent restenosis (ISR). Our goal was to assess the outcomes of ISR patients in a large prospective registry. METHODS: A total of 2329 consecutive patients with ISR-PCI (675 using DEB and 1654 with DES) were treated in our medical centre from 2010 to 2021. Clinical end points included mortality and major adverse cardiac events (MACE) at 1 year. Clinical outcomes were adjusted for multiple confounders. RESULTS: Mean ages (65.9 ± 11.0 vs 66.1 ± 10.5; P = 0.73) and percentages of female patients (16.6% vs 18.2%; P = 0.353) were similar between both ISR groups. Patients treated with DEB for ISR suffered more from diabetes, hypertension, and previous myocardial infarction (P < 0.01 for all) and presented more frequently with acute coronary syndrome (40.0% vs 34.4%; P = 0.01) compared with patients treated with DES for ISR. One-year MACE was significantly higher in the DEB ISR-PCI group (23.4% vs 19.6%; P = 0.002) compared to the DES ISR-PCI group, but no significant differences in mortality were observed at 1 year between the groups. After adjustment for multiple confounders, DEB ISR-PCI was not associated with increased MACE at 1 year (P = 0.55). CONCLUSIONS: In our large experience, patients treated with DEB for ISR-PCI have higher baseline risk and sustained increased MACE rates compared with DES ISR-PCI patients. After adjustment for confounding variables, clinical outcomes are similar between the groups at 1 year after PCI.

Short- and long-term outcomes of patients with active cancer presenting with an acute coronary syndrome.

BACKGROUND: Management of cancer patients presenting with an acute coronary syndrome (ACS) may be challenging. In this study, we sought to examine whether and how a concomitant diagnosis of active cancer affects patients' management and outcomes following an event of ACS. METHODS: We used a retrospective cohort data analysis of patients from the Acute Coronary Syndrome Israeli Survey (ACSIS) carried out between the years 2016-2021 to compare patients with and without a concomitant diagnosis of active cancer. RESULTS: Of 4913 patients who presented with an ACS, 90 (1.8%) patients had a concomitant active cancer. Cancer patients were older, with a higher prevalence of hypertension and chronic renal failure. The rate of ST-elevation myocardial infarction (STEMI) was similar (40%) between both groups. Cancer patients were less likely to undergo coronary angiography during hospitalization; but once it was performed, the rate of percutaneous coronary intervention was similar. The presence of cancer during an ACS was associated with an increased short- and long-term mortality. In a multivariate analysis, the risk for 1-year mortality remained significantly higher in cancer patient (HR 2.72, 95% CI 1.74-4.24, p < 0.001), and was most prominent in patients presenting with STEMI (HR 5.00, 95% CI 2.40-10.39, p < 0.001). Short- and long-term death rates were also higher in cancer patients after a propensity score matching and adjustment for comorbidities other than cancer. CONCLUSION: Despite significant advances in oncologic and cardiac care, the presence of active cancer in patients with an ACS is still associated with significantly increased risk for 1-year mortality.

Is 90 the New 80? Temporal Trends in Nonagenarians Undergoing Percutaneous Coronary Interventions.

BACKGROUND: Coronary artery disease (CAD) is a leading cause of death in the elderly population. Data regarding percutaneous coronary interventions (PCIs) in nonagenarians are scarce, and differences in long term outcomes between generations remain unclear. We aimed to study the pattern and temporal trends of nonagenarians treated with PCI. MATERIALS AND METHODS: A total of 14,695 patients underwent PCI between 2009-2020. We identified 2,034 (13.8%) octogenarians (age 80-89), and 222 (1.5%) nonagenarians (age 90-99). Endpoints included mortality and major adverse cardiac events (MACE) at 1 year. RESULTS: The number of nonagenarians undergoing PCI has increased substantially during the study time period, from 89 patients in the earlier time period (2009-2014) to 133 patients in the later time period (2015-2020). At 1-year, nonagenarians had significantly higher rates of both death (24.3% vs. 14.9%, p<0.01), and MACE (30.6% vs. 22.0%, p<0.01), as compared to octogenarians. The cumulative survival rate was higher among octogenarians both in the early and late time period (p<0.01 and p=0.039, respectively). A significant reduction in nonagenarian MACE rates were observed during the study time period, resulting in a non-significant difference in MACE rates in the later time period between both groups. CONCLUSION: The number of nonagenarians who undergo PCI is on the rise. While their clinical outcomes are inferior as compared to younger age groups, improvement was noted in the late time period.

Empiric Usage of "Anti-Pseudomonal" Agents for Hospital-Acquired Urinary Tract Infections.

Hospital-acquired urinary tract infection (HAUTI) is one of the most common hospital-acquired infections, and over 80% of HAUTI are catheter-associated (CAUTI). Pseudomonas aeruginosa, as well as other non-glucose fermenting Gram negative organisms (NGFGN, e.g., Acinetobacter baumannii), are frequently covered empirically with "anti-Pseudomonals" being administered for every HAUTI (and CAUTI). However, this common practice was never trialed in controlled settings in order to quantify its efficacy and its potential impacts on hospitalization outcomes. There were 413 patients with HAUTI that were included in this retrospective cohort study (2017-2018), 239 (57.9%) had CAUTI. There were 75 NGFGN infections (18.2% of HAUTI, 22.3% of CAUTI). P. aeruginosa was the most common NGFGN (82%). Despite multiple associations per univariable analysis, recent (3 months) exposure to antibiotics was the only independent predictor for NGFGN HAUTI (OR = 2.4, CI-95% = 1.2-4.8). Patients who received empiric anti-Pseudomonals suffered from worse outcomes, but in multivariable models (one for each outcome), none were independently associated with the empiric administration of anti-Pseudomonals. To conclude, approximately one of every five HAUTI (and CAUTI) are due to NGFGN, which justifies the practice of empiric anti-Pseudomonals for patients with HAUTI (and CAUTI), particularly patients who recently received antibiotics. The practice is not associated with independent deleterious impacts on outcomes.

Demographic and Clinical Features of Pediatric Uveitis in Israel.

Purpose: To report the epidemiology, etiology, ocular characteristics, treatment and visual outcome of pediatric uveitis in Israel.Methods: Retrospective study from two tertiary uveitis centers.Results: Included were 107 patients (182 eyes), 55% females. Mean age at diagnosis 8.8 years. Uveitis was predominantly anterior, idiopathic, bilateral, and chronic. Systemic associations were seen in 36% of patients of which the most common disease was juvenile idiopathic arthritis. Infectious uveitis accounted for 37% of posterior uveitis cases of which toxoplasmosis was the most common cause. Anterior segment complications were commonly observed at presentation (41%); the most predominant were posterior synechiae, cataract, and band keratopathy. The most common posterior segment complications were papillitis, epiretinal membrane, and macular atrophy/scar. Ninety-three percent of eyes had visual acuity >20/40 at last follow-up.Conclusion: The pattern of pediatric uveitis in Israel is similar to that in the western world. Visual outcome was good in most eyes.
