Perceptions of the Addictiveness of Low-Nicotine Cigarettes Versus Typical Cigarettes and Exposure to Tobacco Industry-Sponsored Corrective Campaign.

BACKGROUND: In 2017, the U.S. Food and Drug Administration (FDA) announced a regulatory plan to reduce the nicotine content of cigarettes. This study examines the association of exposure to industry-sponsored corrective statements on perceptions of the addictiveness of low-nicotine cigarettes relative to typical cigarettes within the general US population. METHODS: The study comprised 4975 US adult respondents of the 2019 Health Information National Trends Survey (HINTS 5, Cycle 3). Multinomial logistic regression models were used to examine associations between exposure to tobacco industry corrective messages and perceptions of the addictiveness of low-nicotine cigarettes relative to typical cigarettes. RESULTS: In the overall population, 4.1% reported that low-nicotine cigarettes were much more addictive than typical cigarettes, 67.5% said they were equally addictive, while 28.4% reported they were slightly/much less addictive. Adults exposed to industry-sponsored corrective messages had higher odds of perceiving low-nicotine cigarettes as equally addictive as typical cigarettes (aOR 1.57; 95% CI, 1.13-2.19) than those who saw no corrective messages. Those exposed to the corrective messages specifically about the addictiveness of smoking and nicotine had higher odds of perceiving low-nicotine cigarettes as equally addictive as typical cigarettes (aOR, 1.73; 95% CI, 1.07-2.81) compared to those who saw no corrective message. CONCLUSIONS: Our findings suggest that exposure to court-ordered tobacco industry corrective statements may have reinforced perceptions on the addictive potential of nicotine. However, study findings indicate a need for campaigns specifically tailored to address misperceptions observed in this study.

67.5% of US adults perceived low-nicotine cigarettes and typical cigarettes as being equally addictiveExposure to court-ordered corrective statements increased the odds of equal addictiveness perceptionExposure to corrective statements specifically tailored to addiction increased the odds of equal addictiveness perception.

Case Series and Review of Literature for Superior Vena Cava Injury During Laser Lead Extraction.

Transvenous laser lead extraction poses a risk of major complications (0.19%-1.8%), notably injury to the superior vena cava (SVC) in 0.19% to 0.96% of cases. Various factors contribute to SVC injury, which can be categorized as patient-related (such as female gender, low body mass index, diabetes, renal problems, anemia, and reduced ejection fraction), device-related (including the number, dwell time, and type of leads), or procedural-related (such as reason for extraction, venous obstructions, and bilateral lead placements).

Clinical effects of physiologic lesion testing in influencing treatment strategy for multi-vessel coronary artery disease.

Background: The application of fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) in multivessel coronary artery disease (CAD) patients has not been definitively explored. We herein assessed how treatment strategies were decided based on FFR/iFR values in vessels selected clinically. Specifically, we sought to determine whether treatment selection was based on whether the vessel tested was the clinical target stenosis. Methods: 270 consecutive patients with angiographically determined multivessel disease who underwent FFR/iFR testing were included. Patients were classified initially based on their angiographic findings, then re-evaluated from FFR/iFR results (normal or abnormal). Tested lesions were classified into target or non-target lesions based on clinical and non-invasive evaluations. Results: Abnormal FFR/iFR values were demonstrated in 51.9 % of patients, in whom 51.4 % received coronary stenting (PCI) and 44.3 % had bypass surgery (CABG). With two-vessel CAD patients, medical therapy was preferred when the target lesion was normal (72.6 %), while PCI was preferred when it was abnormal (78.4 %). In non-target lesions, PCI was preferred regardless of FFR/iFR results (78.0 %). With three-vessel CAD patients, CABG was preferred when the target lesion was abnormal (68.5 %), and there was no difference in the selected modality when it was normal. Furthermore, the incidence of tested lesions was higher in the left anterior descending (LAD) compared to other coronary arteries, and two-vessel CAD patients with LAD stenoses were more frequently treated by PCI. Conclusion: The use of invasive physiologic testing in multivessel CAD patients may alter the preferred treatment strategy, leading to an overall increase in PCI selection.

Contemporary Trends in Clinical Characteristics, Therapeutic Strategies and Outcomes in Patients Aged 80 Years and Older Presenting with non-ST Elevation Myocardial Infarctions in the United States.

The current guidelines for the management and treatment of acute coronary syndromes do not fully consider the role of age in guiding medical or invasive management. We investigated the characteristics, management strategies, and clinical outcomes of patients aged 80 years and older presenting with non-ST elevation myocardial infarction (NSTEMI). A cohort study using the nationwide inpatient sample database of patients aged 80 years and older presenting with NSTEMI in the United States between 2012 to 2018 was performed. About 24.2% (151,472/625,916) of NSTEMI patients were 80 years and older. Older patients (≥80 years) had higher in-hospital mortality and cardiovascular complications compared to younger patients (odds ratio (OR) 1.79, 95% confidence intervals (CI) 1.71-1.88, P < 0.001). Among older patients, conservative medical management was associated with higher inpatient mortality compared to percutaneous coronary intervention (PCI) (OR 2.3, 95% CI 2.18-2.41, P < 0.001) or coronary artery bypass graft (CABG) (OR 1.9, 95% CI 1.76-2.09, P < 0.001). The highest mortality rate was observed in older patients who underwent both PCI and CABG, followed by those treated conservatively and those undergoing coronary angiography without revascularization. This study provides valuable insights into the clinical characteristics and outcomes of elderly patients presenting with NSTEMI in the United States. The results emphasize the importance of a tailored approach to the management of ACS in elderly patients and the need for improved revascularization strategies to reduce in-hospital mortality and adverse cardiovascular outcomes. Therefore, the clinician should tailor the management of older patients presenting with NSTEMI.

Utility of Intracardiac Echocardiography for Infective Endocarditis and Cardiovascular Device-Related Endocarditis: A Contemporary Systematic Review.

The diagnosis of infective endocarditis (IE) can pose a significant challenge, particularly in cases of prosthetic valve endocarditis (PVE) or cardiac device-related endocarditis (CDIE) (1). While echocardiography remains a crucial diagnostic tool for identifying IE, including PVE and CDIE, there are certain circumstances where transesophageal echocardiography (TEE) may not be conclusive or practically feasible (2). Recently, intracardiac echocardiography (ICE) has emerged as a promising alternative for diagnosing IE and evaluating intracardiac infections, especially in cases where transthoracic echocardiography (TTE) has not been revealing, and TEE has been contraindicated. Furthermore, ICE has been found to be useful in guiding transvenous lead extractions in infected implantable cardiac devices (3). This systematic review aims to comprehensively explore the various applications of ICE in the diagnosis of IE and assess its efficacy in comparison to traditional diagnostic methods.

In-hospital outcomes of transapical versus surgical aortic valve replacement: from the U.S. national inpatient sample.

OBJECTIVE: To compare the outcomes of transapical transcatheter aortic valve replacement (TA-TAVR) and surgical aortic valve replacement (SAVR) using a large US population sample. METHODS: The U.S. National Inpatient Sample was queried for all patients who underwent TA-TAVR or SAVR during the years 2016-2017. The primary outcome was all-cause in-hospital mortality. Secondary outcomes were in-hospital stroke, pericardiocentesis, pacemaker insertion, mechanical ventilation, vascular complications, major bleeding, acute kidney injury, length of stay, and cost of hospitalization. Outcomes were modeled using multi-variable logistic regression for binary outcomes and generalized linear models for continuous outcomes. RESULTS: A total of 1560 TA-TAVR and 44,280 SAVR patients were included. Patients who underwent TA-TAVR were older and frailer. Compared to SAVR, TA-TAVR correlated with a higher mortality (4.5% vs. 2.7%, effect size (SMD) = 0.1) and higher periprocedural complications. Following multivariable analysis, both TA-TAVR and SAVR had a similar adjusted risk for in-hospital mortality. TA-TAVR correlated with lower odds of bleeding with (adjusted OR (aOR) = 0.26; 95% CI: 0.18-0.38;P < 0.001), and a shorter length of stay (adjusted mean ratio (aMR) = 0.77; 95% CI: 0.69-0.84; P < 0.001), but higher cost (aMR = 1.18; 95% CI: 1.10-1.28; P < 0.001). No significant differences in other study outcomes. In subgroup analysis, TA-TAVR in patients with chronic lung disease had higher odds for mortality (aOR = 3.11; 95%CI: 1.37-7.08; P = 0.007). CONCLUSION: The risk-adjusted analysis showed that TA-TAVR has no advantage over SAVR except for patients with chronic lung disease where TA-TAVR has higher mortality.

Diagnosis of Infective Endocarditis by Subtype Using 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography: A Contemporary Meta-Analysis.

Background Infective endocarditis (IE) remains a difficult to diagnose condition associated with high mortality. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) has recently emerged as another IE imaging modality, although diagnostic accuracy varies across observational studies and types of IE. This meta-analysis assessed the diagnostic performance of 18F-FDG PET/CT for IE and its subtypes. Methods We searched Pubmed, Cochrane, and Embase from January 1980 to September 2019 for studies reporting both sensitivity and specificity of 18F-FDG PET/CT for IE. Meta-Disc 1.4 was used to pool data for all cases of IE and its subgroups of native valve IE, prosthetic valve IE, and cardiac implantable electronic devices IE. Results We screened 2566 records from the search, assessed 52 full-text articles, and included 26 studies totaling 1358 patients (509 IE cases). Pooled sensitivity and specificity (95% CI, inconsistency I-square statistic) were 0.74 (0.70-0.77, 71.5%) and 0.88 (0.86-0.91, 78.5%) for all cases of endocarditis. Corresponding parameters for native valve IE were sensitivity 0.31 (0.21-0.41, 29.4%) and specificity 0.98 (0.95-0.99, 34.4%); for prosthetic valve IE: sensitivity 0.86 (0.81-0.89, 60.0%) and specificity 0.84 (0.79-0.88, 75.2%); and for cardiac implantable electronic devices IE: sensitivity 0.72 (0.61-0.81, 76.2%) and specificity 0.83 (0.75-0.89, 83.6%). Pooled sensitivities and specificities were higher for the 17 studies since 2015 than the 9 studies published before 2015. Conclusions 18F-FDG PET/CT had high specificity for all IE subtypes; however, sensitivity was markedly lower for native valve IE than prosthetic valve IE and cardiac implantable electronic devices IE. It is, therefore, a useful adjunct modality for assessing endocarditis, especially in the challenging scenarios of prosthetic valve IE and cardiac implantable electronic devices IE, with improving performance over time, related to advances in 18F-FDG PET/CT techniques.

National Trends of Outcomes in Transcatheter Aortic Valve Replacement (TAVR) Through Transapical Versus Endovascular Approach: From the National Inpatient Sample (NIS).

BACKGROUND: To evaluate the trends in complication rates following transcatheter aortic valve replacement (TAVR) procedures according to the type of vascular approach (endovascular vs. transapical) in a large US population sample. METHODS: The National Inpatient Sample (NIS) was queried for all patients diagnosed with aortic stenosis who underwent a TAVR procedure in the United States during the years 2012-2016. Outcomes assessed were peri-procedural mortality, cardiac, and non-cardiac complications. Hospitalization outcomes were modeled using logistic regression for binary outcomes and generalized linear models for continuous outcomes. RESULTS: There were 97,320 endovascular-TAVR patients and 11,140 transapical-TAVR patients. The mean age was 80.8 years (standard error of the mean: ± 0.1). Most patients were males (53.7%) and Caucasian (87.1%). On multivariate analysis, after adjusting for age, gender, comorbidities, as well as hospital factors, patients with the transapical approach had a higher risk for mortality and adverse outcomes. Among the endovascular-TAVR group, national trends showed a diminishing incidence of procedural mortality (incidence rate ratio [IRR] 0.77; 95% CI: 0.72-0.84, p < 0.001), stroke (IRR 0.80; 95% CI: 0.73-0.87, p < 0.001), and all secondary outcomes, but no significant change in myocardial infarction. In contrast, most transapical-TAVR related procedural complications remained unchanged over time, except for a significant decrease in stroke, acute respiratory failure and need for pacemaker insertion. CONCLUSION: National trends show a steady increase in the number of endovascular-TAVR procedures with a concurrent decrease in procedural complications.

Factors influencing the uptake of influenza vaccination in African American patients with heart failure: Findings from a large urban public hospital.

BACKGROUND: Evidence suggests that annual influenza vaccination may prevent acute heart failure exacerbation episodes and improve survival. OBJECTIVE: Determine the influenza vaccination rate among African American patients with heart failure and identify predictors of uptake. METHODS: African American patients with heart failure were recruited at Grady Memorial Hospital, Atlanta GA between October 1, 2017 and April 28, 2018 (N = 281). All participants completed a questionnaire. RESULTS: Mean age of the sample was 50.5 ± 11.5 years (58% male). The influenza vaccination rate among the patients was 46% (n = 129/281). Patients who received vaccination information and recommendation from their physician, especially cardiologists, were significantly more likely to be vaccinated than those who did not (P<0.05). Major reasons for declining vaccination included fear of getting sick from influenza vaccine and distrust of the pharmaceutical companies that produce vaccines. CONCLUSIONS: Recommendation of influenza vaccines by physicians during medical consultations and cardiology visits may improve uptake rates in heart failure patients.

Endoscopic Ultrasound Guided Rendezvous Drainage of Biliary Obstruction Using a New Flexible 19-Gauge Fine Needle Aspiration Needle.

Background and Aim. A successful endoscopic ultrasound guided rendezvous (EUS-RV) biliary drainage is dependent on accurate puncture of the bile duct and precise guide wire manipulation across the ampulla of Vater. We aim to study the feasibility of using a flexible 19-gauge fine aspiration needle in the performance of EUS-RV biliary drainage. Method. This is a retrospective case series of EUS-RV biliary drainage procedures at a single center. Patients who failed ERCP during the same session for benign or malignant biliary obstruction underwent EUS-RV using a flexible, nitinol covered, 19-gauge needle for biliary access and guide wire manipulation. Result. 24 patients underwent EUS-RV biliary drainage via extrahepatic access while 1 attempt was via intrahepatic access. The technical success rate was 80%, including 83.3% of cases via extrahepatic access. There was no significant difference in success rate of inpatient and outpatient procedures, benign or malignant indications, or type of guide wire used. Adverse events included mild pancreatitis (3 patients) and cholangitis (1 patient). Conclusion. A flexible 19-gauge needle for biliary access can be safe and effective when used to perform EUS-RV biliary drainage. Direct comparison between the nitinol needle and conventional metal needles in the performance of EUS guided biliary drainage is needed.
