Survival Differences in Men and Women With Primary Malignant Cardiac Tumor: An Analysis Using the Surveillance, Epidemiology and End Results (SEER) Database From 1973 to 2015.

Background No data are available on sex disparities in prevalence and survival for primary malignant cardiac tumors (PMCT). This study aimed to compare male and female PMCT prevalence and long-term survival rates. Methods and Results We utilized the Surveillance, Epidemiology, and End Results (SEER) 18 database from the National Cancer Institute for all PMCTs diagnosed between 1973 and 2015. From a total of 7 384 580 cases of cancer registered in SEER, we identified 327 men and 367 women with PMCTs. The majority (78%) of patients were white. Sarcoma was the most common type of PMCT in both men and women (≈60%). Individuals diagnosed with lymphoma exhibited better survival than those with other types of PMCTs. Men were diagnosed at a younger age than women; however, there was no significant difference in overall survival between the sexes. Men diagnosed with PMCT between the ages of 51 and 65 years demonstrated prolonged survival compared with those diagnosed at younger or older ages. There was no difference in survival rates among women based on age at diagnosis. Conclusions PMCTs are rare in both men and women. Tumors tend to be diagnosed at an earlier age in men compared with women, but there is no sex disparity in survival rate. Sarcoma is the most common type of PMCT, and lymphoma is associated with the highest survival rate among both sexes.

Percutaneous mitral valve repair for secondary mitral valve regurgitation: A systematic review and meta-analysis.

BACKGROUND: The first two randomized control trials (RCTs) studying the role of MitraClip in patients with secondary mitral regurgitation (MR) had antagonizing results. We, therefore, performed an updated meta-analysis of RCTs and propensity score-matched observational studies investigating the role of MitraClips in patients with secondary MR. A novel method of Kaplan Meier Curve reconstruction from derived individual patient data will be used to compare the survival probability of control groups in COAPT and MITRA HF trail, and hence, access inter-study heterogeneity. METHODS: Medline and Cochrane databases was used for systematic search. We used the Mantel-Haenszel method with a random-effect model to calculate risk ratio (RR) with 95% confidence interval (CI) and inverse variance method with a random-effect model to calculate the mean difference (MD) with 95% confidence interval (CI). We used a fixed-effect approach for meta-regression. RESULTS: MitraClip reduced the risk of all-cause mortality [RR: 0.72, CI: 0.55-0.95, P value = 0.02, I2 = 55%, χ2P-value = 0.08] and readmission [RR: 0.62, CI: 0.42-0.92, P value = 0.02, I2 = 90%, χ2P-value<0.01] at two years follow-up. There was no effect of MitraClip on change in cardiovascular mortality and 6 m walking distance at 12 months follow-up. Meta-regression indicated left ventricular end diastolic volume and age among the factors affecting outcomes. Reconstructed Kaplan Meier curves confirmed considerable heterogeneity among patients randomized in MITRA HF and COAPT trial. CONCLUSION: The present meta-analysis confirms the beneficial role of percutaneous mitral valve repair in patients with secondary MR. However, all the results were associated with considerable heterogeneity.

Impact of chronic kidney disease on in-hospital outcomes following left ventricular assist device placement: A national perspective.

BACKGROUND: Left ventricular assist devices (LVADs) are being increasingly utilized for the treatment of stage-D heart failure. A LVAD is a battery-operated, mechanical pump that assists in pumping blood out of the left ventricle (LV) into the aorta, thereby lowering left ventricular burden. Prevalence of chronic kidney disease (CKD) is increasing in patients receiving LVAD. OBJECTIVES: The purpose of this study was to compare in-hospital mortality and hospitalization expenditure associated with CKD in patients receiving LVAD implantation. METHODS: Using the National Inpatient Sample from January 2012 through September 2015, index hospitalizations for LVAD were identified. Based on kidney function, LVAD recipients were divided into three groups: Group 1 included patients with normal renal function or CKD stages I-III. Groups 2 and 3 comprised of patients with CKD stage IV/V, and end-stage renal disease on dialysis respectively. RESULTS: A total of 20,656 patients received LVAD during the study period. Mean age was 56.1 years; 76.8% were men. In a fully adjusted model, in-hospital mortality was higher in group 2 (OR: 1.33, CI: 1.16-1.50) and highest in group 3 (OR: 8.95, CI: 6.90-11.61). Similarly, the length of hospitalization, and hospitalization cost were higher in group 2 and highest in group 3. CONCLUSION: Despite improving outcomes in patients receiving LVAD, CKD remained a significant health problem. Worsening in-hospital outcomes paralleling the degree of kidney dysfunction were observed in patients receiving LVADs in this study.

Incidence and implications of acute kidney injury in patients hospitalized with acute decompensated heart failure.

Acute kidney injury (AKI) is a common complication in patients hospitalized with heart failure (HF). There is a paucity of research on the incidence and consequences of AKI among patients hospitalized with HF who do not have evidence of chronic kidney disease (CKD). The National Inpatient Sample database was used to identify index hospitalizations for acute HF from January 2012 through September 2015. The incidence of new-onset AKI was determined, and the study population was divided into two groups: HF with AKI (HFwAKI) and HF without AKI (HFwoAKI). These groups were further divided into the subgroups HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF). A total of 2,010,095 index hospitalizations for HF were identified. The incidence of new-onset AKI was found to be ~ 20% for this population. In a fully adjusted model, in-hospital mortality was higher in the HFwAKI group (adjusted OR 3.63, P ≤ 0.001) and higher among patients with HFrEF (adjusted OR 3.85), as opposed to patients with HFpEF (adjusted OR 3.21). Similarly, length of stay and cost of care for the HFwAKI group were significantly higher as well. New-onset AKI among hospitalizations for HF poses a significant health problem, especially considering the increasing prevalence of HF. Further research into the causes of AKI among HF hospitalizations is, therefore, important as it will enable the development of treatment strategies to prevent AKI in HF hospitalizations and, consequently, benefit both the patients and health care system of the United States.

Mesalamine-Induced Myopericarditis: A Case Report and Literature Review.

Inflammation of the myocardium (myocarditis) or pericardium (pericarditis) or both (myopericarditis) as side effects of mesalamine, a drug widely used in the treatment of inflammatory bowel disease, is a rare, but potentially lethal complication. We report a case of myopericarditis occurring in a young Caucasian woman 14 days following initiation of mesalamine therapy for treatment of a newly diagnosed ulcerative colitis (UC). She presented with pleuritic chest pain, elevated troponin levels and pre-syncope. The diagnosis of myopericarditis was made based on the clinical features, electrocardiogram (EKG) and cardiac magnetic resonance, which showed trace pericardial effusion. The patient's symptom and condition were dramatically improved upon discontinuing mesalamine, and a full recovery was achieved. Mesalamine-induced inflammation of the myocardium (myocarditis) or pericardium (pericarditis) or both (myopericarditis) is rare, but has fatal side effects. Early recognition of these side effects by clinicians and patients is important to prevent progression of the inflammation. Furthermore, patients should be educated to seek urgent medical attention if cardiac symptoms arise.

'Acute leukemia in congenital methehemoglobinemia - an enigma to explore'.

Congenital methemoglobinemia is a rare disease, resulting in increased oxygen affinity and impaired oxygen delivery to the tissues. While there have been studies that have linked acquired methemoglobinemia in almost 79% of leukemia patients, to the best of our knowledge, this is the first case of leukemia development in a patient with congenital methemoglobinemia. Chronic deprivation of oxygen to metabolically active bone marrow can theoretically lead to hematopoietic disorders. It would be interesting to further investigate if presence of congenital methemoglobinemia is a risk factor for developing acute leukemia.

Comparison of Baseline Characteristics and In-hospital Outcomes in Medicaid Versus Private Insurance Hospitalizations for Atrial Fibrillation.

The prevalence of atrial fibrillation (Afib) has been increasing over the past few decades. There are very few comparisons of health insurance plans available that incorporate measurement of co-morbidities and in-hospital outcomes. We sought to compare an impact of Medicaid versus private insurance (PI) on outcomes in hospitalizations with Afib. The US National Inpatient Sample database from years January 2010 to September 2015 was used to identify adult (≥18 years) Afib hospitalizations, whose payment source was either Medicaid or PI. We included propensity score-matched analysis for comparison of outcomes between the groups. In a total of 3,264,258 Afib hospitalizations, 22.9% hospitalizations were insured with Medicaid, while 77.1% had PI. Compared with PI, Medicaid beneficiaries (MB) were younger (59 vs 64 years), fewer were men (55.15% vs 63.16%), and fewer were Caucasians (52.66% vs 81.67%; all p<0.0001). As suggested by Charlson co-morbidity index ≥3, more MB (40.86%) had the significantly higher burden of co-morbidities compared with PI (29.87%; p<0.0001). About 83% of Afib hospitalizations had a CHA2DVASC2 score ≥2 in both the groups. After adjusting for confounders, in-hospital mortality was significantly higher (4.8% vs 4.3%, p = 0.02) in MB compared with PI. In MB, 55.3% hospitalizations were discharged to home and their median length of hospital stay was 5 days, whereas 61.3% hospitalizations with PI were discharged to home and their median length of stay was 4 days (p<0.0001). In conclusion, this extensive study of Afib hospitalizations, Medicaid group had greater co-morbidities, marginally higher in-hospital mortality, longer length of stay, and lesser disposition to home as compared with PI group.

Missed opportunities: unnecessary medicine use in patients with lung cancer at the end of life - an international cohort study.

AIMS: The aims of the current study were: (i) to examine the prescribing of preventative medication in a cohort of people with advanced lung cancer on hospital admission and discharge across different healthcare systems; and (ii) to explore the factors that influence preventative medication prescribing at hospital discharge. METHODS: A retrospective cohort study was conducted across two centres in the UK and the US. The prescribing of preventative medication was examined at hospital admission and discharge for patients who died of lung cancer. A zero-inflated negative binomial regression model was used to examine the association between preventative medications at discharge and patient- and hospital-based factors. The classes of preventative medication prescribed included were: vitamins and minerals, and antidiabetic, antihypertensive, antihyperlipidaemic and antiplatelet medications. RESULTS: In the UK site (n = 125), the mean number of preventative medications prescribed was 1.9 [standard deviation (SD) 1.7) on admission, and 1.7 (SD 1.7) on discharge, and in the US site (n = 191) the mean was 2.6 (SD 2.2) on admission and 1.9 (SD 2.2) on discharge. The model found a significant association between the number of preventative drugs prescribed on admission and the number on discharge; it also found a significant association between the total number of drugs prescribed on discharge and the number of preventative medications on discharge. Other indicators related to patient and hospital factors were not significantly associated with the number of preventative medications supplied on discharge. CONCLUSIONS: The use of preventative medication was common in lung cancer patients, despite undergoing discharge. Patient- and hospital-based factors did not influence the prescribing of preventative medication.

A fatal case of diffuse alveolar hemorrhage as the initial presentation of systemic lupus erythematosus: A case report and literature review.

Diffuse alveolar hemorrhage (DAH) is a rare fatal pulmonary complication of systemic lupus erythematosus (SLE). The clinical syndrome is characterized by hemoptysis, acute fall in hematocrit, hypoxemic respiratory failure, and diffuses pulmonary infiltrates. We describe a case of 23-year-old female who presented with Ludwig's angina that was complicated by diffuse alveolar hemorrhage as the initial presentation of undiagnosed systemic lupus erythematosus. A high index of suspicion is need for prompt diagnosis and treatment in order to avoid the high mortality associated with such cases.

A Fatal Case of Non-Uremic Calciphylaxis: A Case Report and Literature Review.

BACKGROUND Calciphylaxis is a rare cutaneous disease, also known as calcific uremic arteriolopathy, that occurs most frequently in patients with advanced chronic kidney disease and on long-term hemodialysis. CASE REPORT We describe the case of a 61-year-old female patient with worsening chronic kidney disease not on dialysis therapy, who presented with severe progressive calciphylaxis on both lower limbs. CONCLUSIONS Calcific uremic arteriolopathy is a rare fatal condition that requires prompt diagnosis and treatment. It is classically described in patients with end-stage kidney disease on long-term renal replacement therapy but can present in patients with an earlier stage of kidney disease. Non-uremic calciphylaxis should be suspected in patients with earlier stages of kidney disease, especially in those with other concurrent risk factors or co-morbid conditions, to avoid the high risk of morbidity and mortality associated with such cases.

Recurrent Unilateral Transudative Pleural Effusion Due to Low Flow, Low Gradient Severe Aortic Stenosis.

BACKGROUND In symptomatic severe aortic stenosis (AS), the majority of patients have high gradient AS. However, some patients have an AS gradient less than 40 with a valve area under 1.0 cm². For patients with a low gradient, severe AS is difficult to detect and requires a high index of suspicion. Transcatheter aortic valve replacement (TAVR) is currently recommended for patients with moderate to high risk AS according to the Society of Thoracic Surgery (STS) risk score. CASE REPORT Here we present the case of an 86-year-old female with recurrent pleural effusion over the course of 2-year; she had multiple thoracentesis procedures and was being considered for a pleurodesis. Later the patient was found to have severe AS; an echocardiogram showed an aortic valve (AV) area of 0.67 cm², AV mean gradient of 34 mmHg, and ejection fraction of 75%. The patient underwent a diagnostic cardiac catheterization and was treated with TAVR. CONCLUSIONS The diagnosis was made after exclusion of all other causes of unilateral pleural effusion and was confirmed by improvement of effusion following the TAVR procedure.

Coronary Artery-Left Ventricular Fistula and Takotsubo Cardiomyopathy - An Association or an Incidental Finding? A Case Report.

BACKGROUND A coronary artery-left ventricular fistula is an anomalous communication between the coronary arteries and the cardiac chambers and is a rare congenital coronary anomaly that is often small and asymptomatic. Takotsubo cardiomyopathy, on the other hand, is a syndrome characterized by transient regional systolic dysfunction of the left ventricle, mimicking myocardial infarction, but in the absence of angiographic evidence of obstructive coronary artery disease or acute plaque rupture. We present the case of an elderly woman who presented with Takotsubo cardiomyopathy and who was incidentally discovered to have an associated coronary artery-left ventricular fistula. CASE REPORT We report the case of a 68-years-old woman with a family history of premature cardiac diseases who presented with ischemic chest pain and elevated troponin levels. Her EKG and troponins were suggestive of non-ST-elevation myocardial infarction (NSTEMI), for which she was initially treated medically and later underwent coronary angiography. Unexpectedly, the angiography revealed patent coronary arteries, and we discovered evidence of coronary artery to left ventricular fistula in the addition to angiographic evidence of Takotsubo cardiomyopathy. A working diagnosis of Takotsubo was made, for which she was treated medically with resulting improvement of her symptoms and later in the imaging findings. CONCLUSIONS This described case illustrates a rare association between coronary artery fistulas and Takotsubo cardiomyopathy. It is unclear if this association has played a role in the pathogenesis or perhaps is just an incidental finding. More similar cases are needed to expand the clinical presentation of both conditions and add to the literature.

A case of spontaneous coronary artery dissection presenting with acute anterior wall myocardial infarction in a young adult male - an increasingly recognized rare disease.

Background: Spontaneous coronary artery dissection (SCAD) is increasingly recognized as an important cause of myocardial infarction and sudden death. Although some correlations have been noted in relation to aetiology, no direct causes have been identified in a large number of patients. Most of the patients are women in peripartum period or of childbearing age, with few if any risk factors for coronary heart disease. In men, however, risk factors for atherosclerosis are more prevalent in cases of SCAD Case report: We report a case of a 43-years-old healthy male, with no known risk factors, who presented with ischemic chest pain and elevated troponin levels. He underwent an emergent percutaneous transluminal coronary angiography which revealed a total occlusion of the left anterior descending artery at its origin with an evidence of spontaneous dissection as the cause of the occlusion, which was subsequently treated with placement of a drug-eluting stent and thrombectomy from the distal occluded portion. This case highlights the importance of including spontaneous coronary artery dissection as a cause of ischemic cardiac insults and illustrates the approach to treatment. Conclusion: Internists should have a low threshold of clinical suspicion for SCAD especially in a young patient with no known risk factors and should know the importance of emergency in management.
