Pathologic Outcomes in Single Versus Multiple Areas of Architectural Distortion on Digital Breast Tomosynthesis.

BACKGROUND. Digital breast tomosynthesis (DBT) has led to increased detection of architectural distortion (AD). Management of patients with multiple areas of AD is not established. OBJECTIVE. The purpose of this article is to compare pathologic outcomes between single and multiple areas of AD identified on DBT. METHODS. This retrospective study included 402 patients (mean age, 56 years) who underwent image-guided core needle biopsy of AD visualized on DBT between April 7, 2017, and April 16, 2019. Patients were classified as having a single or multiple areas of AD according to the presence of distinct areas of AD described in the clinical radiology reports. The pathologic diagnosis for each AD was on the basis of the most aggressive pathology identified on either biopsy or surgical excision, if performed. Patients with single and multiple areas of AD were compared. RESULTS. The sample included 372 patients with a single AD (145 benign, 121 high risk, 105 malignant, one other) and 30 patients with multiple visualized ADs, including 66 biopsied ADs (10 benign, 35 high risk, 21 malignant). At pathologic assessment on a per-lesion basis, multiple compared with single ADs showed higher frequency of high-risk pathology (53.0% vs 32.5%, p = .002) but no difference in frequency of malignancy (31.8% vs 28.2%, p = .56). In multivariable analysis of a range of patient-related characteristics, the presence of single versus multiple areas of AD was not independently associated with malignancy (p = .51). In patients with multiple areas of AD, the most aggressive pathology (benign, high risk, or malignant) across all ADs was not associated with the number of ADs (p = .73). In 8 of 24 patients with at least two ipsilateral biopsied ADs, the ipsilateral areas varied in terms of most aggressive pathology; in 5 of 10 patients with contralateral biopsied ADs, the contralateral areas varied in most aggressive pathology. CONCLUSION. The presence of multiple areas of AD, compared with a single AD, was significantly more likely to yield high-risk pathology but was not significantly different in yield of malignancy. In patients with multiple ADs, multiple ipsilateral or contralateral ADs commonly varied in pathologic classification (benign, high risk, or malignant). CLINICAL IMPACT. These findings may help guide management of AD visualized by DBT, including multiple ADs. For patients with multiple areas of AD, biopsy of all areas may be warranted given variation in pathologic diagnoses.

A Single-Center Study of Adherence to Breast Cancer Screening Mammography Guidelines by Transgender and Non-Binary Patients.

BACKGROUND: Adherence to screening guidelines among transgender and non-binary (TGNB) populations is not well studied. This study examines breast cancer screening patterns among TGNB patients at an urban academic medical center. METHODS: Demographic information, risk factors, and screening mammography were collected. Mammography rates were calculated in populations of interest according to national guidelines, and mammogram person-years were also calculated. Univariate and multivariate logistic regression was performed. RESULTS: Overall, 253 patients were analyzed: 193 transgender women and non-binary people designated male at birth (TGNB DMAB) and 60 transgender men and non-binary people designated female at birth (TGNB DFAB). The median (interquartile range) age was 53.2 years (42.3-62.6). Most patients had no family history of breast cancer (n = 163, 64.4%) and were on hormone therapy (n = 191, 75.5%). Most patients where White (n = 164, 64.8%), employed (n = 113, 44.7%), and had public insurance (n = 128, 50.6%). TGNB DFAB breast screening rates were low, ranging from 2.0 to 50.0%, as were TGNB DMAB screening rates, ranging from 7.1 to 47.6%. The screening rates among the TGNB DFAB and TGNB DMAB groups did not significantly differ from one another. Among TGNB DFAB patients, univariate analyses showed no significant predictors for mammography. Among TGNB DMAB patients, not being on hormone therapy resulted in fewer odds of undergoing mammography. There were no significant findings on multivariate analyses. CONCLUSION: Mammography rates in the TGNB population are lower than institutional and national rates for cisgender patients, which are 77.3% and 66.7-78.4%, respectively. Stage of transition, organs present, hormone therapy, and risk factors should be considered to guide screening.

Nipple Discharge: Current Clinical and Imaging Evaluation.

OBJECTIVE. Nipple discharge is a common complaint that is first evaluated with clinical assessment. Physiologic discharge does not require imaging other than routine screening mammography. Initial evaluation of pathologic nipple discharge involves mammography and ultrasound. evaluation of pathologic nipple discharge involves mammography and ultrasound. Because of its high sensitivity in detecting breast malignancy and its biopsy capability, MRI is increasingly used in lieu of ductography. CONCLUSION. The problem-solving algorithm for evaluating suspicious nipple discharge is evolving. When diagnostic imaging for evaluation of pathologic nipple discharge is negative, management is based on clinical suspicion. If additional imaging is warranted, MRI is preferred because of its increased sensitivity, specificity, and patient comfort. Although central duct excision is the current standard for evaluation of malignancy in patients with pathologic nipple discharge, studies suggest that, given the high negative predictive value of MRI, surveillance may be a reasonable alternative to surgery.

Cardio-oncology Training in the COVID-19 Era.

OPINION STATEMENT: Cardio-oncology is a field dedicated to the prevention, diagnosis, and management of cardiovascular disease in cancer patients before, during, and after cancer therapy. It is an emerging field with limited opportunities for structured education and training. In the year 2021, we cannot define the requirements of cardio-oncology training without acknowledging the impact of the global coronavirus disease 19 (COVID-19) pandemic. While this pandemic poses significant health risks to patients with cancer and cardiovascular disease as well as the providers who care for them, it also allows novel opportunities for the nascent field of cardio-oncology to readily adapt. In this article, we detail how the COVID-19 pandemic has impacted all aspects of cardio-oncology training, how programs and trainees can adapt to these challenges, and how lessons learned from the COVID-19 era can continue to positively impact cardio-oncology training for the foreseeable future.

Cardiovascular magnetic resonance in immune checkpoint inhibitor-associated myocarditis.

AIMS: Myocarditis is a potentially fatal complication of immune checkpoint inhibitors (ICI). Sparse data exist on the use of cardiovascular magnetic resonance (CMR) in ICI-associated myocarditis. In this study, the CMR characteristics and the association between CMR features and cardiovascular events among patients with ICI-associated myocarditis are presented. METHODS AND RESULTS: From an international registry of patients with ICI-associated myocarditis, clinical, CMR, and histopathological findings were collected. Major adverse cardiovascular events (MACE) were a composite of cardiovascular death, cardiogenic shock, cardiac arrest, and complete heart block. In 103 patients diagnosed with ICI-associated myocarditis who had a CMR, the mean left ventricular ejection fraction (LVEF) was 50%, and 61% of patients had an LVEF ≥50%. Late gadolinium enhancement (LGE) was present in 48% overall, 55% of the reduced EF, and 43% of the preserved EF cohort. Elevated T2-weighted short tau inversion recovery (STIR) was present in 28% overall, 30% of the reduced EF, and 26% of the preserved EF cohort. The presence of LGE increased from 21.6%, when CMR was performed within 4 days of admission to 72.0% when CMR was performed on Day 4 of admission or later. Fifty-six patients had cardiac pathology. Late gadolinium enhancement was present in 35% of patients with pathological fibrosis and elevated T2-weighted STIR signal was present in 26% with a lymphocytic infiltration. Forty-one patients (40%) had MACE over a follow-up time of 5 months. The presence of LGE, LGE pattern, or elevated T2-weighted STIR were not associated with MACE. CONCLUSION: These data suggest caution in reliance on LGE or a qualitative T2-STIR-only approach for the exclusion of ICI-associated myocarditis.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of severe gastrointestinal and hepatic toxicities from checkpoint inhibitors.

Immune-related adverse events (IrAEs) affecting the gastrointestinal (GI) tract and liver are among the most frequent and most severe inflammatory toxicities from contemporary immunotherapy. Inflammation of the colon and or small intestines (entero)colitis is the single most common GI IrAE and is an important cause of delay of discontinuation of immunotherapy. The severity of these GI IrAEs can range from manageable with symptomatic treatment alone to life-threatening complications, including perforation and liver failure. The frequency and severity of GI IrAEs is dependent on the specific immunotherapy given, with cytotoxic T lymphocyte antigen (CTLA)-4 blockade more likely to induce severe GI IrAEs than blockade of either programmed cell death protein 1 (PD-1) or PD-1 ligand (PD-L1), and combination therapy showing the highest rate of GI IrAEs, particularly in the liver. To date, we have minimal prospective data on the appropriate diagnosis and management of GI IrAEs, and recommendations are based largely on retrospective data and expert opinion. Although clinical diagnoses of GI IrAEs are common, biopsy is the gold standard for diagnosis of both immunotherapy-induced enterocolitis and hepatitis and can play an important role in excluding competing, though less common, diagnoses and ensuring optimal management. GI IrAEs typically respond to high-dose corticosteroids, though a significant fraction of patients requires secondary immune suppression. For colitis, both TNF-α blockade with infliximab and integrin inhibition with vedolizumab have proved highly effective in corticosteroid-refractory cases. Detailed guidelines have been published for the management of low-grade GI IrAEs. In the setting of more severe toxicities, involvement of a GI specialist is generally recommended. The purpose of this review is to survey the available literature and provide management recommendations focused on the GI specialist.

Cancer immunotherapy-related adverse events: causes and challenges.

Despite the success and ongoing promise of monoclonal antibody-targeted immune checkpoint inhibitor immunotherapy of advanced malignancies, in particular, antibodies directed against CTLA-4 and PD-1/PD-L1, the development of immune-related adverse events (irAEs) remains a constraint of this type of therapy. Although rarely fatal, the occurrence of irAEs may necessitate discontinuation of immunotherapy, as well as administration of corticosteroids or other immunosuppressive therapies that may not only compromise efficacy but also predispose for development of opportunistic infection. Clearly, retention of efficacy of immune checkpoint-targeted therapies with concurrent attenuation of immune-mediated toxicity represents a formidable challenge. In this context, the current brief review examines mechanistic relationships between these events, as well as recent insights into immunopathogenesis, and strategies which may contribute to resolving this issue. These sections are preceded by brief overviews of the discovery and functions of CTLA-4 and PD-1, as well as the chronology of the development of immunotherapeutic monoclonal antibodies which target these immune checkpoint inhibitors.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of immune-related adverse events: pulmonary toxicity.

The immune checkpoints associated with the CTLA-4 and PD-1 pathways are critical modulators of immune activation. These pathways dampen the immune response by providing brakes on activated T cells, thereby ensuring more uniform and controlled immune reactions and avoiding immune hyper-responsiveness and autoimmunity. Cancer cells often exploit these regulatory controls through a variety of immune subversion mechanisms, which facilitate immune escape and tumor survival. Immune checkpoint inhibitors (ICI) effectively block negative regulatory signals, thereby augmenting immune attack and tumor killing. This process is a double-edged sword in which release of regulatory controls is felt to be responsible for both the therapeutic efficacy of ICI therapy and the driver of immune-related adverse events (IrAEs). These adverse immune reactions are common, typically low-grade and may affect virtually every organ system. In the early clinical trials, lung IrAEs were rarely described. However, with ever-expanding clinical applications and more complex ICI-containing regimens, lung events, in particular, pneumonitis, have become increasingly recognized. ICI-related lung injury is clinically distinct from other types of lung toxicity and may lead to death in advanced stage disease. Thus, knowledge regarding the key characteristics and optimal treatment of lung-IrAEs is critical to good outcomes. This review provides an overview of lung-IrAEs, including risk factors and epidemiology, as well as clinical, radiologic, and histopathologic features of ICI-related lung injury. Management principles for ICI-related lung injury, including current consensus on steroid refractory pneumonitis and the use of other immune modulating agents in this setting are also highlighted.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of severe dermatological toxicities from checkpoint inhibitors.

Immune checkpoint inhibitors (ICIs) frequently result in cutaneous immune-related adverse events (IrAEs). Although the majority of these events are mild-to-moderate in severity, up to 5% are severe, which may lead to morbidity and dose interruption or discontinuation of ICI therapy. In addition, up to 25% of dermatologic IrAEs are corticosteroid-refractory or corticosteroid-dependent. These 2020 MASCC recommendations cover the diagnosis and management of cutaneous IrAEs with a focus on moderate-to-severe and corticosteroid-resistant events. Although the usage of immune-suppressive therapy has been advocated in this setting, there is a lack of randomized clinical trial data to provide a compelling level of evidence of its therapeutic benefit.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of immune-mediated cardiovascular, rheumatic, and renal toxicities from checkpoint inhibitors.

Immune checkpoint inhibitors (ICIs) have emerged as the newest pillar of cancer treatment. Immune-mediated toxicities, stemming from increased activity within the T cell lineage, range from asymptomatic or mild complications to those that are fulminant and potentially fatal. Although they are of variable occurrence, cardiovascular, rheumatic, and renal immune-mediated toxicities are among the most serious of these adverse events. We present MASCC recommendations with respect to the workup and management of cardiovascular, rheumatic, and renal immune-mediated toxicities with a focus on presentations that require treatment with immunomodulating agents.

Multinational Association of Supportive Care in Cancer (MASCC) 2020 clinical practice recommendations for the management of immune checkpoint inhibitor endocrinopathies and the role of advanced practice providers in the management of immune-mediated toxicities.

Immune checkpoint inhibitors (ICIs) have emerged as the newest pillar of cancer treatment, transforming outcomes in melanoma and showing benefit in a range of malignancies. Immune-mediated toxicities, stemming from increased activity within the T cell lineage, range from asymptomatic or mild complications to those that are fulminant and potentially fatal. Immune-mediated endocrinopathies include hypophysitis, thyroiditis, and insulin-dependent diabetes mellitus. These presentations, which may be vague and non-specific, can be life-threatening if not diagnosed and treated appropriately. This review considers the work-up and management of immune-mediated endocrinopathies and also considers the role of advanced practice practitioners in the management of immune-mediated toxicities. These state-of-the-art MASCC recommendations represent a comprehensive overview of the management and clinical work-up in those in whom the diagnosis should be considered.

Exercise Therapy and Cardiovascular Toxicity in Cancer.

Cardio-oncology is an emerging discipline focused predominantly on the detection and management of cancer treatment-induced cardiac dysfunction (cardiotoxicity), which predisposes to development of overt heart failure or coronary artery disease. The direct adverse consequences, as well as those secondary to anticancer therapeutics, extend beyond the heart, however, to affect the entire cardiovascular-skeletal muscle axis (ie, whole-organism cardiovascular toxicity). The global nature of impairment creates a strong rationale for treatment strategies that augment or preserve global cardiovascular reserve capacity. In noncancer clinical populations, exercise training is an established therapy to improve cardiovascular reserve capacity, leading to concomitant reductions in cardiovascular morbidity and its attendant symptoms. Here, we overview the tolerability and efficacy of exercise on cardiovascular toxicity in adult patients with cancer. We also propose a conceptual research framework to facilitate personalized risk assessment and the development of targeted exercise prescriptions to optimally prevent or manage cardiovascular toxicity after a cancer diagnosis.

Myocarditis Surveillance in Patients with Advanced Melanoma on Combination Immune Checkpoint Inhibitor Therapy: The Memorial Sloan Kettering Cancer Center Experience.

This letter to the editor describes myocarditis screening among patients undergoing combination immune checkpoint inhibitor therapy, in light of the consensus document from the Checkpoint Inhibitor Safety Working Group.

Combined effect of ZnO nanoripples and solvent additive on the nanomorphology and performance of PTB7-Th: PC71BM organic solar cells.

In bulk heterojunction organic solar cells (OSCs), nanomorphology of the photoactive layer plays a crucial role in determining photocurrent and fill factor (FF) of OSCs, and therefore it is essential to control the nanomorphology of the photoactive layer to fabricate devices with high power conversion efficiency (PCE). We demonstrate the combined effects of a ZnO nanorippled electron transport layer (ETL) and solvent additive (1,8-diiodooctane (DIO)) on the nanomorphology and performance of a model OSC in an inverted geometry. The photoactive layer in the model OSC is composed of Poly [4,8-bis (5-(2-ethylhexyl)thiophen-2-yl)benzo[1,2-b;4,5-b']dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl] (PTB7-Th):phenyl-C71-butyric acid methyl ester (PC71BM) blend. It is observed that the use of ZnO nanoripples as an ETL and DIO as a solvent additive facilitates the formation of near ideal nanomorphology of bi-continuous interpenetrating network of donor and acceptor. This is confirmed by morphological studies using atomic force microscopy, scanning electron microscopy and transmission electron microscopy. Photo-electrochemical impedance spectroscopy measurements confirm that obtained nanomorphology of bicontinuous interpenetrating network is contributing to the improved device performance. The device with 3 vol% DIO, with underneath ZnO nanoripples exhibited improved current density (J sc), FF, open circuit voltage (V oc) and PCE of 15.57 mA cm-2, 64.50%, 0.81V and 8.20%, respectively.

Development and Validation of a Clinical Score for Cardiovascular Risk Stratification of Long-Term Childhood Cancer Survivors.

BACKGROUND: Long-term childhood cancer survivors (CCS) are at increased risk of adverse cardiovascular events; however, there is a paucity of risk-stratification tools to identify those at higher-than-normal risk. SUBJECTS, MATERIALS, AND METHODS: This was a population-based study using data from the Surveillance, Epidemiology, and End Results Program (1973-2013). Long-term CCS (age at diagnosis ≤19 years, survival ≥5 years) were followed up over a median time period of 12.3 (5-40.9) years. Independent predictors of cardiovascular mortality (CVM) were combined into a risk score, which was developed in a derivation set (n = 22,374), and validated in separate patient registries (n = 6,437). RESULTS: In the derivation registries, older age at diagnosis (≥10 years vs. reference group of 1-5 years), male sex, non-white race, a history of lymphoma, and a history of radiation were independently associated with an increased risk of CVM among long-term CCS (p < .05). A risk score derived from this model (Childhood and Adolescence Cancer Survivor CardioVascular score [CHACS-CV], range: 0-8) showed good discrimination for CVM (Harrell's C-index [95% confidence interval (CI)]: 0.73 [0.68-0.78], p < .001) and identified a high-risk group (CHACS-CV ≥6), with cumulative CVM incidence over 30 years of 6.0% (95% CI: 4.3%-8.1%) versus 2.6% (95% CI: 1.8%-3.7%), and 0.7% (95% CI: 0.5%-1.0%) in the mid- (CHACS-CV = 4-5) and low-risk groups (CHACS-CV ≤3), respectively (plog-rank < .001). In the validation set, the respective cumulative incidence rates were 4.7%, 3.1%, and 0.8% (plog-rank < .001). CONCLUSION: We propose a simple risk score that can be applied in everyday clinical practice to identify long-term CCS at increased cardiovascular risk, who may benefit from early cardiovascular screening, and risk-reduction strategies. IMPLICATIONS FOR PRACTICE: Childhood cancer survivors (CCS) are known to be at increased cardiovascular risk. Currently available prognostic tools focus on treatment-related adverse events and late development of congestive heart failure, but there is no prognostic model to date to estimate the risk of cardiovascular mortality among long-term CCS. A simple clinical tool is proposed for cardiovascular risk stratification of long-term CCS based on easily obtainable information from their medical history. This scoring system may be used as a first-line screening tool to assist health care providers in identifying those who may benefit from closer follow-up and enable timely deployment of preventive strategies.

Practitioner Gender and Quality of Care in Ambulatory Cardiology Practices: A Report From the National Cardiovascular Data Practice Innovation and Clinical Excellence (PINNACLE) Registry.

BACKGROUND: Some studies suggest that female practitioners are more likely to provide guideline-concordant care than male practitioners; however, little is known about the role of practitioner gender in cardiology. OBJECTIVE: The aim of the study was to measure the association between practitioner gender and adherence to the cardiovascular performance measures in the American College of Cardiology's ambulatory Practice Innovation and Clinical Excellence Registry. METHODS: Patients with at least 1 outpatient visit with a unique practitioner were included. Among eligible patients, adherence to 7 guideline-supported performance measures for coronary artery disease, heart failure, and atrial fibrillation over 12 months after registry entry was compared by practitioner gender using hierarchical models adjusting for practitioner type (physicians vs advance practice practitioners) and number of visits. RESULTS: The study cohort included 1493 individual practitioners who saw 769 139 patients; 80% of practitioners were men. Male practitioners were more often physicians compared with female practitioners (98.2% vs 43.7%, P < .01). Accounting for practitioner category and visit frequency, guideline adherence rates were similar by practitioner gender for all measures with the exception of marginally higher rates for coronary artery disease performance measures for male practitioners compared with female practitioners (antiplatelet: rate ratio [RR] = 1.06; 95% confidence interval [CI], 1.03-1.09; ß-blockers: RR = 1.06; 95% CI, 1.01-1.10; and lipid-lowering drug: RR = 1.07; 95% CI, 1.04-1.10) and atrial fibrillation (oral anticoagulants: RR = 1.05; 95% CI, 1.01-1.09). CONCLUSION: Male practitioners marginally outperformed their female counterparts in ambulatory practices enrolled in a voluntary cardiovascular performance improvement registry program. Overall low adherence to some performance measures suggests room for improvement among all practitioners.

Aspirin Is Associated with Improved Survival in Severely Thrombocytopenic Cancer Patients with Acute Myocardial Infarction.

BACKGROUND: Patients with hematologic malignancies are at risk for severe thrombocytopenia (sTP). The risk and benefit of aspirin are not known in thrombocytopenic cancer patients experiencing acute myocardial infarction (AMI). MATERIALS AND METHODS: Medical records of patients with hematologic malignancies diagnosed with AMI at Memorial Sloan Kettering Cancer Center during 2005-2014 were reviewed. sTP was defined as a platelet count <50,000 cells per µL within 7 days of AMI. RESULTS: Of 118 patients with hematologic malignancies who had AMI, 58 (49%) had sTP. Twenty-five patients (43%) with sTP received aspirin as a treatment for AMI. Compared with patients without sTP with AMI, patients with sTP with AMI were less likely to receive aspirin (83% vs. 43%; p = .0001) and thienopyridine treatment (27% vs. 3%; p = .0005). During median follow-up of 3.7 years after AMI, survival was lower in patients with sTP than in those with no sTP (23% vs. 50% at 1 year; log rank p = .003). Patients with sTP who received aspirin for AMI had improved survival compared with those who did not (92% vs. 70% at 7 days, 72% vs. 33% at 30 days, and 32% vs. 13% at 1 year; log rank p = .008). In multivariate regression models, aspirin use was associated with improved 30-day survival both in the overall patient cohort and in sTP patients. No fatal bleeding events occurred. Major bleeding was not associated with sTP or aspirin use. CONCLUSION: Treatment of AMI with aspirin in patients with hematologic malignancies and sTP is associated with improved survival without increase in major bleeding. The Oncologist 2017;22:213-221Implications for Practice: In patients with hematologic malignancies and acute myocardial infarction with severe thrombocytopenia (platelet count < 50,000 cells/µL), guideline-recommended medical therapy is often withheld because of the fear of major bleeding. In this study, aspirin therapy was associated with improved survival without an increase in major bleeding in this high-risk patient cohort.

Prognostic utility of differential tissue characterization of cardiac neoplasm and thrombus via late gadolinium enhancement cardiovascular magnetic resonance among patients with advanced systemic cancer.

BACKGROUND: Late gadolinium enhancement (LGE-) cardiovascular magnetic resonance (CMR) is well-validated for cardiac mass (CMASS) tissue characterization to differentiate neoplasm (CNEO) from thrombus (CTHR): Prognostic implications of CMASS subtypes among systemic cancer patients are unknown. METHODS: CMASS + patients and controls (CMASS -) matched for cancer diagnosis and stage underwent a standardized CMR protocol, including LGE-CMR (IR-GRE) for tissue characterization and balanced steady state free precession cine-CMR (SSFP) for cardiac structure/function. CMASS subtypes (CNEO, CTHR) were respectively defined by presence or absence of enhancement on LGE-CMR; lesions were quantified for tissue properties (contrast-to-noise ratio (CNR); signal-to-noise ratio (SNR) and size. Clinical follow-up was performed to evaluate prognosis in relation to CMASS etiology. RESULTS: The study population comprised 126 patients with systemic neoplasms referred for CMR, of whom 50% (n = 63) had CMASS + (CNEO = 32%, CTHR = 18%). Cancer etiology differed between CNEO (sarcoma = 20%, lung = 18%) and CTHR (lymphoma = 30%, GI = 26%); cardiac function (left ventricular ejection fraction: 63 ± 9 vs. 62 ± 10%; p = 0.51∣ right ventricular ejection fraction: 53 ± 9 vs. 54 ± 8%; p = 0.47) and geometric indices were similar (all p = NS). LGE-CMR tissue properties assessed by CNR (13.1 ± 13.0 vs. 1.6 ± 1.0; p < 0.001) and SNR (29.7 ± 20.4 vs. 15.0 ± 11.4, p = 0.003) were higher for CNEO, consistent with visually-assigned diagnostic categories. CTHR were more likely to localize to the right atrium (78% vs. 25%, p < 0.001); nearly all (17/18) were associated with central catheters. Lesion size (17.3 ± 23.8 vs. 2.0 ± 1.5 cm2; p < 0.001) was greater with CNEO vs. CTHR, as was systemic disease burden (cancer-involved organs: 3.6 ± 2.0 vs. 2.3 ± 2.1; p = 0.02). Mortality during a median follow-up of 2.5 years was markedly higher among patients with CNEO compared to those with CTHR (HR = 3.13 [CI 1.54-6.39], p = 0.002); prognosis was similar when patients were stratified by lesion size assessed via area (HR = 0.99 per cm2 [CI 0.98-1.01], p = 0.40) or maximal diameter (HR = 0.98 per cm [CI 0.91-1.06], p = 0.61). CTHR conferred similar mortality risk compared to cancer-matched controls without cardiac involvement (p = 0.64) whereas mortality associated with CNEO was slightly higher albeit non-significant (p = 0.12). CONCLUSIONS: Among a broad cancer cohort with cardiac masses, CNEO defined by LGE-CMR tissue characterization conferred markedly poorer prognosis than CTHR, whereas anatomic assessment via cine-CMR did not stratify mortality risk. Both CNEO and CTHR are associated with similar prognosis compared to CMASS - controls matched for cancer type and disease extent.

Clinical Profile of Dysphagia in Patients with Parkinson's Disease, Progressive Supranuclear Palsy and Multiple System Atrophy.

BACKGROUND: Swallowing changes are commonly observed in Parkinson's and Parkinsonism plus syndromes. Expeditious identification is necessary to provide early intervention in this population to avoid risk of aspiration and swallowing complications. OBJECTIVE: To investigate swallowing problems using detailed case history and swallowing speed on 3 ounce water test in three groups i.e. PD, MSA and PSP groups and further, to compare it with control group. SUBJECT AND METHODS: Cross sectional study design. A total of 73 patients were classified in MSA, PSP and PD for testing aged between 38 yrs and 70 yrs according to respective diagnostic criteria. A simple bedside water swallowing test was performed using 90 cc of water. Detailed assessment was done to check swallowing function. RESULTS: The mean age of both experimental group and control group was 62.4±8.37 yrs. and 61.05±7.07 yrs. Males were affected more in every pathological group compared to females. The dysphagia presented earlier in PSP and MSA groups as compared to PD groups. The water swallowing speed was found to be significantly less than 10ml/sec amongst three neurological groups compared to control group. The patients were found to have significant difficulty in parameters like repetitive swallowing, transferring food bolus through mouth, and food sticking in throat after swallowing. CONCLUSIONS: This is the first study comparing clinical profile of dysphagia in patients with PD, MSA, and PSP. Although there is no specific pattern of dysphagia for each of these disorders, the presence of some findings may provide clue to the diagnosis and necessary intervention.
