- Abstract
When dislodged stents remain on the coronary wire, the wire can be snared outside of the body (presnaring), and the snare loop advanced over the wire into the body to retrieve the stent. Presnaring may be a valuable technique to retrieve dislodged coronary stents when the stent remains on the coronary wire, as demonstrated in the 2 patients described.

- Abstract
Background & Aims: Patients with cirrhosis and significant coronary artery disease (CAD) are at risk of peri-liver transplantation (LT) cardiac events. The coronary artery disease in liver transplantation (CAD-LT) score and algorithm aim to predict the risk of significant CAD in LT candidates and guide pre-LT cardiac evaluation., Methods: Patients who underwent pre-LT evaluation at Indiana University (2010-2019) were studied retrospectively. Stress echocardiography (SE) and cardiac catheterization (CATH) reports were reviewed. CATH was performed for predefined CAD risk factors, irrespective of normal SE. Significant CAD was defined as CAD requiring percutaneous or surgical intervention. A multivariate regression model was constructed to assess risk factors. Receiver-operating curve analysis was used to compute a point-based risk score and a stratified testing algorithm., Results: A total of 1,771 pre-LT patients underwent cardiac evaluation, including results from 1,634 SE and 1,266 CATH assessments. Risk-adjusted predictors of significant CAD at CATH were older age (adjusted odds ratio 1.05; 95% CI 1.03-1.08), male sex (1.69; 1.16-2.50), diabetes (1.57; 1.12-2.22), hypertension (1.61; 1.14-2.28), tobacco use (pack years) (1.01; 1.00-1.02), family history of CAD (1.63; 1.16-2.28), and personal history of CAD (6.55; 4.33-9.90). The CAD-LT score stratified significant CAD risk as low (≤2%), intermediate (3% to 9%), and high (≥10%). Among patients who underwent CATH, a risk-based testing algorithm (low: no testing; intermediate: non-invasive testing vs. CATH; high: CATH) would have identified 97% of all significant CAD and potentially avoided unnecessary testing (669 SE [57%] and 561 CATH [44%])., Conclusions: The CAD-LT score and algorithm (available at www.cad-lt.com) effectively stratify pre-LT risk for significant CAD. This may guide more targeted testing of candidates with fewer tests and faster time to waitlist., Lay Summary: The coronary artery disease in liver transplantation (CAD-LT) score and algorithm effectively stratify patients based on their risk of significant coronary artery disease. The CAD-LT algorithm can be used to guide a more targeted cardiac evaluation prior to liver transplantation., Competing Interests: Conflict of interest The authors declare no conflicts of interest that pertain to this work.

- Abstract
Background: Targeted temperature management (TTM) improves neurologic outcome after cardiac arrest. However, better neurologic prognostication is needed., Objective: The purpose of this study was to test the hypothesis that noninvasive recording of skin sympathetic nerve activity (SKNA) and its association with heart rate (HR) during TTM may serve as a biomarker of neurologic status., Methods: SKNA recordings were analyzed from 29 patients undergoing TTM. Patients were grouped based on Clinical Performance Category (CPC) score into group 1 (CPC 1-2) representing a good neurologic outcome and group 2 (CPC 3-5) representing a poor neurologic outcome., Results: Of the 29 study participants, 18 (62%) were deemed to have poor neurologic outcome. At all timepoints, low average skin sympathetic nerve activity (aSKNA) was associated with poor neurologic outcome (odds ratio 22.69; P = .002) and remained significant (P = .03) even when adjusting for presenting clinical factors. The changes in aSKNA and HR during warming in group 1 were significantly correlated (ρ = 0.49; P <.001), even when adjusting for corresponding temperature and mean arterial pressure measurements (P = .017), whereas this correlation was not observed in group 2. Corresponding to high aSKNA, there was increased nerve burst activity during warming in group 1 compared to group 2 (0.739 ± 0.451 vs 0.176 ± 0.231; P = .013)., Conclusion: Neurologic recovery was retrospectively associated with SKNA. Patients undergoing TTM who did not achieve neurologic recovery were associated with low SKNA and lacked a significant correlation between SKNA and HR. These preliminary results indicate that SKNA may potentially be a useful biomarker to predict neurologic status in patients undergoing TTM., (Copyright © 2021 Heart Rhythm Society.

- Abstract
Objective: To identify patients undergoing complex, high-risk indicated percutaneous coronary intervention (CHIP-PCI) and compare their outcomes with non-CHIP patients. We created a CHIP score to risk stratify these patients., Background: Risk stratification of PCI patients remains difficult because most scoring systems reflect hemodynamic instability and predict early mortality., Methods: CHIP-PCI was defined as any of the following: age >80 years; ejection fraction <30%; dialysis; prior bypass surgery; treatment of left main trunk; chronic total occlusion; or >2 lesions in >1 coronary artery. The primary endpoint was 1-year all-cause mortality. Logistic regression identified independent predictors of 1-year mortality and the odds ratios (ORs) for those predictors were used to create a CHIP score. Patients were then classified as low, intermediate, and high risk., Results: Among 4478 patients, a total of 1730 (38.6%) were CHIP. There were 85 deaths (2.2%) at 1 year (4.1% in CHIP patients and 1.0% in non-CHIP patients; P<.001). CHIP-PCI was an independent predictor of mortality (OR, 2.57; 955 confidence interval, 1.52-4.32; P<.001). Four CHIP criteria were independent predictors of mortality: age >80 years (3 points); dialysis (6 points); ejection fraction <30% (2 points); and number of lesions treated >2 (2 points). Accordingly, there were 2752 low-risk (score of 0), 889 intermediate-risk (score of 2-3), and 267 high-risk patients (score of 4-13). The 1-year mortality rates among these 3 groups were 1.24%, 2.47%, and 10.86%, respectively (P<.001)., Conclusion: Compared with non-CHIP, CHIP-PCI is associated with increased risk of 1-year mortality, which is particularly evident among those fulfilling >1 CHIP criterion.

- Abstract
As the severe acute respiratory syndrome coronavirus 2 virus pandemic continues to grow globally, an association is apparent between patients with underlying cardiovascular disease comorbidities and the risk of developing severe COVID-19. Furthermore, there are potential cardiac manifestations of severe acute respiratory syndrome coronavirus 2 including myocyte injury, ventricular dysfunction, coagulopathy, and electrophysiologic abnormalities. Balancing management of the infection and treatment of underlying cardiovascular disease requires further study. Addressing the increasing reports of health care worker exposure and deaths remains paramount. This review summarizes the most contemporary literature on the relationship of the cardiovascular system and COVID-19 and society statements with relevance to protection of health care workers, and provides illustrative case reports in this context., (Published by Elsevier Inc.)

- Abstract
Background and Aims: A study at Indiana University demonstrated a reduction in myocardial infarction (MI) incidence with increased frequency of cardiac catheterization (CATH) in liver transplant (LT) candidates. A strict protocol for performing CATH based upon predefined risk factors, rather than noninvasive testing alone, was applied to a subgroup (2009-2010) from that study. CATH was followed by percutaneous coronary intervention (PCI) in cases of significant coronary artery disease (CAD; ≥50% stenosis). The current study applies this screening protocol to a larger cohort (2010-2016) to assess post-LT clinical outcomes., Approach and Results: Among 811 LT patients, 766 underwent stress testing (94%) and 559 underwent CATH (69%), of whom 10% had CAD requiring PCI. The sensitivity of stress echocardiography in detecting significant CAD was 37%. Predictors of PCI included increasing age, male gender, and personal history of CAD (P < 0.05 for all). Compared to patients who had no CATH, patients who underwent CATH had higher mortality (P = 0.07), and the hazard rates (HR) for mortality increased with CAD severity (normal CATH, HR, 1.35; 95% confidence interval [CI], 0.79-2.33; P = 0.298; nonobstructive CAD, HR, 1.53; 95% CI, 0.84-2.77; P = 0.161; and significant CAD, HR, 1.96; 95% CI, 0.93-4.15; P = 0.080). Post-LT outcomes were compared to the 2009-2010 subgroup from the previous study and showed similar 1-year overall mortality (8% and 6%, P = 0.48), 1-year MI incidence (<1% and <1%, P = 0.8), and MI deaths as a portion of all deaths (3% and 9%, P = 0.35)., Conclusions: Stress echocardiography alone is not reliable in screening LT patients for CAD. Aggressive CAD screening with CATH is associated with low rate of MI and cardiac mortality and validates the previously published protocol when extrapolated over a larger sample and longer follow-up period., (© 2019 American Association for the Study of Liver Diseases.)

- Abstract
Postoperative atrial fibrillation/flutter (POAF) is the most common perioperative arrhythmia and may be particularly problematic after liver transplantation (LT). This study is a single-center retrospective analysis of POAF to determine its incidence following LT, to identify risk factors, to assess its impact on clinical outcomes, and to summarize management strategies. The records of all patients who underwent LT between 2010 and 2018 were reviewed. Extracted data included pre-LT demographics and cardiac evaluation, in-hospital post-LT cardiac events, early and late complications, and survival. Among 1011 patients, the incidence of post-LT POAF was 10%. Using binary logistic regression, pre-LT history of atrial fibrillation was the strongest predictor of POAF (odds ratio [OR], 6.72; 95% confidence interval [CI], 2.00-22.57; P < 0.001), followed by history of coronary artery disease (CAD; OR, 2.52; 95% CI, 1.10-5.81; P = 0.03). Cardiac stress testing abnormality and CAD on cardiac catheterization were also associated with higher risk. Median time to POAF onset after LT was 3 days with 72% of cases resolving within 48 hours. POAF patients had greater hospital length of stay, death during the LT admission, and 90-day and 1-year mortality. POAF was an independent risk factor for post-LT mortality (OR, 2.0; 95% CI, 1.3-3.0; P < 0.01). Amiodarone was administered to 73% of POAF patients with no evidence of increased serum alanine aminotransferase levels. POAF occurred in 10% of post-LT patients with early onset and rapid resolution in most affected patients. POAF patients, however, had significant morbidity and mortality, suggesting that POAF is an important marker for worse early and late post-LT outcomes., (Copyright © 2019 by the American Association for the Study of Liver Diseases.)

- Abstract
Dual-antiplatelet therapy is recommended for all patients with acute coronary syndromes (ACS), regardless of performance of revascularization. Ticagrelor (T) was shown to be superior to clopidogrel (C) in a large, randomized clinical trial, but data from real-world practice are lacking. We identified ACS patients from our institutional registry who underwent percutaneous coronary intervention and received one of the two drugs at hospital discharge based on physician preference. Among 1439 patients, there were 774 patients (53.8%) in the C group and 665 patients (46.2%) in the T group. T and C patients were similar except for a higher incidence of ST-elevation myocardial infarction (MI) and lower frequency of prior MI in the T group (P<.05 for both). The primary endpoint - 1-year all-cause death - occurred in 58 C patients and 48 T patients (6.9% vs 7.9%, respectively; P=.42). Sixty percent of these deaths (n = 62; 31 C and 31 T) were considered cardiovascular in nature based on chart review. By multivariable logistic regression model, only dialysis (hazard ratio [HR], 2.64; 95% confidence interval [CI], 1.50-4.64; P=.01), age (HR, 1.83; 95% CI, 1.49-2.24 per 10 years; P<.001), and prior heart failure (HR, 1.78; 95% CI, 1.12-2.82; P=.02) were independent predictors of 1-year death. Treatment with T was not a predictor of death (HR, 1.21; 95% CI, 0.81-1.82; P=.35) or cardiovascular death (HR, 1.18; 95% CI, 0.72-1.94; P=.52). Landmark analysis from day 10 showed similar results (HR, 1.13; 95% CI, 0.71-1.84; P=.59). Thus, we conclude that C and T have similar rates of 1-year all-cause mortality, which is predominantly affected by age, end-stage renal disease, and pre-existing heart failure.

- Abstract
Disseminated histoplasmosis among immunocompetent patients is rare, but may be associated with clinically significant refractory thrombocytopenia. Platelet counts often return to normal levels following antifungal therapy. Therefore, the most important management of this refractory thrombocytopenia is the recognition and treatment of histoplasmosis infection.

- Abstract
Mutations in the gap junction protein connexin47 (Cx47) are associated with lymphedema. However, the role of Cx47 in lymphatic pathophysiology is unknown. We demonstrate that Cx47 is expressed in lymphatic endothelial cells by whole-mount immunostaining and qPCR. To determine if Cx47 plays a role in lymphatic vessel function we analysed Cx47-/- mice. Cx47-deficiency did not affect lymphatic contractility (contractile amplitude or frequency) or lymphatic morphology (vessel diameter or number of valves). Interstitial fluid drainage or dendritic cell migration through lymphatic vessels was also not affected by Cx47-deficiency. Cx47 is dispensable for long-chain fatty acid absorption from the gut but rather promotes serum lipid handling as prolonged elevated triglyceride levels were observed in Cx47-deficient mice after oral lipid tolerance tests. When crossed with Apolipoprotein E-deficient (Apoe-/-) mice, LDL-cholesterol was decreased in young Cx47-/-Apoe-/- adults as compared to Apoe-/- mice, which was inverted later in life. Finally, advanced atherosclerotic plaques in thoracic-abdominal aortas of 15 months-old mice tended to be larger in Cx47-/-Apoe-/- mice. These plaques contained fewer macrophages but similar amounts of T lymphocytes, collagen and lipids than plaques of Apoe-/- mice. In conclusion, Cx47 is expressed in lymphatic endothelium and seems modestly implicated in multiple aspects of lymphatic pathophysiology.

Objective: To obtain normative data for nasalance scores in Middle Eastern English-speaking adult population., Design: Cross-sectional study., Participants: A total of 102 subjects were recruited in the study, 26 were excluded, thus, 77 Middle Eastern English-speaking adults (mean age = 23.77 ± 4.295; 39 males, 38 females) with normal speech and no hearing problems participated in the study., Interventions: Using Nasometer II 6450, nasalance scores were obtained for each participant's readings of 3 passages: Zoo and Rainbow passages and nasal sentences., Main Outcome Measures: Mean nasalance score, standard deviation and range., Results: Mean nasalance scores for Zoo passage, Rainbow passage and nasal sentences were 25.21 ± 11.07, 34.04 ± 9.30 and 41.29 ± 9.87 respectively. Mean scores didn't differ significantly between males and females, though scores for the Zoo passage were slightly higher among males (26.51 ± 11.66) than females (23.87 ± 10.42). In within-session reliability testing, 86% of retests for all three passages fell within 5 nasalance points of the previous test. In across-session reliability testing, 93% of retests for all 3 passages were within 5 points of initial test., Conclusions and Relevance: This study provides normative data for nasalance scores among Middle-Eastern adults, which can help make nasometer and determination of nasalance more clinically useful in this population.

- Abstract
Background: Atherosclerosis is a chronic inflammatory disease of large- to medium-sized arteries and is the main underlying cause of death worldwide. The lymphatic vasculature is critical for processes that are intimately linked to atherogenesis such as the immune response and cholesterol metabolism. However, whether lymphatic vessels truly contribute to the pathogenesis of atherosclerosis is less clear despite increasing research efforts in this field., Design: PubMed and Ovid MEDLINE databases were searched. In addition, key review articles were screened for relevant original publications., Results: Current knowledge about lymphatic vessels in the arterial wall came from studies that examined the presence and location of such vessels in human atherosclerotic plaque specimens, as well as in a variety of arteries in animal models for atherosclerosis (e.g. rabbits, dogs, rats and mice). Generally, three experimental approaches have been used to investigate the functional role of plaque-associated lymphatic vessels; experimental lymphostasis was used to investigate lymphatic drainage of the arterial wall, and more recently, studies with genetic interventions and/or surgical transplantation have been performed., Conclusions: Lymphatic vessels seem to be mostly present in the adventitial layer of the arterial walls of animals and humans. They are involved in reverse cholesterol transport from atherosclerotic lesions, and arteries with a dense lymphatic network seem naturally protected against atherosclerosis. Lymphangiogenesis is a process that is an important part of the inflammatory loop in atherosclerosis. However, how augmenting or impeding the distribution of lymphatic vessels impacts disease progression remains to be investigated in future studies., (© 2014 Stichting European Society for Clinical Investigation Journal Foundation.)

- Abstract
Purpose: To analyze the correlation between acoustic parameters and body height, weight, and mass composition in young males., Material: A total of 40 male subjects were included in this study. Each subject underwent acoustic analysis using the Kay Elemetric VISI Pitch (Model 3300, KayPentax, Lincoln Park, NJ) and complete body mass analysis. Pearson correlation was calculated to estimate the strength of the relationship between acoustic parameters and each of the weight analysis variables., Results: The mean age of the male subjects was 24 years with a range between 18 and 40 years. The average weight and height were almost 80 and 180cm, with standard deviation (SD) of 7.42 and 10.46, respectively. The fat weight ranged between 3 and 25kg, with the main concentration being in the extremities, 61.84%±17.4 and less concentrated in the trunk, 16.20% ± 7.6. The mean fundamental frequency was 120.13Hz with an SD of 19.16Hz. The mean Habitual Pitch was 114.16Hz with an SD of 16.55Hz. There was no significant correlation between the acoustic parameters and any of the body composition variables, in particular fat weight and distribution. There was a weak correlation between Shimmer, trunk fat (r value=0.328, P=0.039), and muscle mass (r value=0.326, P=0.038)., Conclusion: The body mass composition and distribution do not correlate significantly with the fundamental frequency and the Habitual pitch., (Copyright © 2012 The Voice Foundation.
