Solitary Pleural Fibroma: A Case Report and Review of Literature.

Solitary fibrous tumors ofthe pleura (SFTP) are uncommon. They tend to be discovered incidentally or during workup for unexplained cough or paraneoplastic effects. It is important to recognize the entityand perform a surgical excision because of the possibility of subsequent malignant transformation and local compressive effects. We present the case of a SFTP discovered on chest imaging. Our patient had surgical excision with good response. A review of the literature is also presented.

Statins and cognitive function: an updated review.

Ischemic heart disease remains the leading cause of death in the USA. Statins have substantially contributed to the decline in mortality due to heart disease. Historically, statins are hypothesized to be neuroprotective and beneficial in dementia, but recent reports have suggested an association with transient cognitive decline. We have critically appraised the relationship between statins and cognitive function in this review. Most of the data are observational and reported a protective effect of statins on dementia and Alzheimer's disease in patients with normal cognition at baseline. Few studies, including two randomized control trials, were unable to find a statistically significant decrease in the risk or improvement in patients with established dementia or decline in cognitive function with statin use. As more randomized control trials are required to definitively settle this, cardiovascular benefits of statins must be weighed against the risks of cognitive decline on an individual basis.

Health-related quality of life after transcatheter or surgical aortic valve replacement in high-risk patients with severe aortic stenosis: an updated review of literature.

Recent trials have highlighted the comparable mortality benefits and durability of the results for patients with severe aortic stenosis (AS) and high surgical risk managed with either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (AVR). Various national guidelines and international regulatory bodies have approved TAVR, thereby leading to potential wide usage and dissemination of this technique worldwide. Quality-of-life outcomes, in spite of being an important measure of success and acceptability of the procedure, have not been publicized as extensively. For high risk patients with severe AS, implementation of TAVR has resulted in comparable survival, but different and novel adverse events compared with AVR. We present an updated review focusing on the quality-of-life outcomes and issues with this new and important procedural approach.

Thrombolysis for pulmonary embolism and risk of all-cause mortality, major bleeding, and intracranial hemorrhage: a meta-analysis.

IMPORTANCE: Thrombolytic therapy may be beneficial in the treatment of some patients with pulmonary embolism. To date, no analysis has had adequate statistical power to determine whether thrombolytic therapy is associated with improved survival, compared with conventional anticoagulation. OBJECTIVE: To determine mortality benefits and bleeding risks associated with thrombolytic therapy compared with anticoagulation in acute pulmonary embolism, including the subset of hemodynamically stable patients with right ventricular dysfunction (intermediate-risk pulmonary embolism). DATA SOURCES: PubMed, the Cochrane Library, EMBASE, EBSCO, Web of Science, and CINAHL databases from inception through April 10, 2014. STUDY SELECTION: Eligible studies were randomized clinical trials comparing thrombolytic therapy vs anticoagulant therapy in pulmonary embolism patients. Sixteen trials comprising 2115 individuals were identified. Eight trials comprising 1775 patients specified inclusion of patients with intermediate-risk pulmonary embolism. DATA EXTRACTION AND SYNTHESIS: Two reviewers independently extracted trial-level data including number of patients, patient characteristics, duration of follow-up, and outcomes. MAIN OUTCOMES AND MEASURES: The primary outcomes were all-cause mortality and major bleeding. Secondary outcomes were risk of recurrent embolism and intracranial hemorrhage (ICH). Peto odds ratio (OR) estimates and associated 95% CIs were calculated using a fixed-effects model. RESULTS: Use of thrombolytics was associated with lower all-cause mortality (OR, 0.53; 95% CI, 0.32-0.88; 2.17% [23/1061] vs 3.89% [41/1054] with anticoagulants; number needed to treat [NNT] = 59) and greater risks of major bleeding (OR, 2.73; 95% CI, 1.91-3.91; 9.24% [98/1061] vs 3.42% [36/1054]; number needed to harm [NNH] = 18) and ICH (OR, 4.63; 95% CI, 1.78-12.04; 1.46% [15/1024] vs 0.19% [2/1019]; NNH = 78). Major bleeding was not significantly increased in patients 65 years and younger (OR, 1.25; 95% CI, 0.50-3.14). Thrombolysis was associated with a lower risk of recurrent pulmonary embolism (OR, 0.40; 95% CI, 0.22-0.74; 1.17% [12/1024] vs 3.04% [31/1019]; NNT = 54). In intermediate-risk pulmonary embolism trials, thrombolysis was associated with lower mortality (OR, 0.48; 95% CI, 0.25-0.92) and more major bleeding events (OR, 3.19; 95% CI, 2.07-4.92). CONCLUSIONS AND RELEVANCE: Among patients with pulmonary embolism, including those who were hemodynamically stable with right ventricular dysfunction, thrombolytic therapy was associated with lower rates of all-cause mortality and increased risks of major bleeding and ICH. However, findings may not apply to patients with pulmonary embolism who are hemodynamically stable without right ventricular dysfunction.

Risk factors for intracranial haemorrhage in patients with pulmonary embolism treated with thrombolytic therapy Development of the PE-CH Score.

Pulmonary embolism (PE) is a major cause of morbidity and mortality world-wide, and the use of thrombolytic therapy has been associated with favourable clinical outcomes in certain patient subsets. These potential benefits are counterbalanced by the risk of bleeding complications, the most devastating of which is intracranial haemorrhage (ICH). We retrospectively evaluated 9703 patients from the 2003-2012 nationwide in-patient sample database (NIS) who received thrombolytics for PE. All patients with ICH during the PE hospitalisation were identified and a clinical risk score model was developed utilizing demographics and comorbidities. The dataset was divided 1:1 into derivation and validation cohorts. During 2003-2012, 176/9705 (1.8 %) patients with PE experienced ICH after thrombolytic use. Four independent prognostic factors were identified in a backward logistic regression model, and each was assigned a number of points proportional to its regression coefficient: pre-existing Peripheral vascular disease (1 point), age greater than 65 years (Elderly) (1 point), prior Cerebrovascular accident with residual deficit (5 points), and prior myocardial infarction (Heart attack) (1 point). In the derivation cohort, scores of 0, 1, 2 and ≥ 5 points were associated with ICH risks of 1.2 %, 1.9 %, 2.4 % and 17.8 %, respectively. Rates of ICH were similar in the validation cohort. The C-statistic for the risk score was 0.65 (0.61-0.70) in the derivation cohort and 0.66 (0.60-0.72) in the validation cohort. A novel risk score, derived from simple clinical historical elements was developed to predict ICH in PE patients treated with thrombolytics.

Adherence to Positive Airway Pressure Therapy in Hospitalized Patients with Decompensated Heart Failure and Sleep-Disordered Breathing.

STUDY OBJECTIVES: Sleep-disordered breathing (SDB) has been implicated as a risk factor for the development of several adverse cardiovascular outcomes, but can be mitigated with positive airway pressure therapy (PAP). The nonadherence of patients with SDB on PAP in the outpatient setting ranges from 29% to 84%. However, adherence of PAP in patients with congestive heart failure (CHF) admitted for decompensated CHF and in whom SDB has been diagnosed in the hospital setting is not known. We hypothesized that despite a diagnosis in the hospital, the compliance of these patients with PAP therapy would not be different from the well-established adherence in patients with a diagnosis and treatment in the outpatient setting. METHODS: The study was a retrospective analysis of patients admitted to an academic tertiary care hospital between March 2013 and February 2014. Patients presenting with decompensated CHF were screened and high-risk patients were started on PAP empirically and advised to undergo a postdischarge polysomnogram. Compliance of the patients with PAP was tracked for over 12 mo. Data from a similar outpatient group who underwent polysomnography during the study period were also reviewed. RESULTS: Ninety-one patients underwent polysomnograhy postdischarge. Of the 91 patients, 81 patients agreed to PAP therapy. One patient was excluded as data were missing. The adherence at 3, 6, and 12 mo was 52%, 37%, and 27%, which was not significantly different than an outpatient control group. There was a trend for those with CHF plus SDB and compliant with PAP to have a higher probability of survival compared to those who were noncompliant (p = 0.07). CONCLUSIONS: Adherence of patients to PAP therapy in whom a SDB diagnosis is made during acute hospitalization for heart failure is comparable to patients in the ambulatory setting. Adherence in first 3 mo is a predictive marker for improved survival trend.

Pre-procedural Elevated White Blood Cell Count and Neutrophil-Lymphocyte (N/L) Ratio are Predictors of Ventricular Arrhythmias During Percutaneous Coronary Intervention.

AIMS: The absolute white blood cell (WBC) count and neutrophil to lymphocyte (N/L) ratio are predictors of death/myocardial infarction in patients who have undergone coronary angiography. We hypothesized that a pre-procedural elevated WBC count and an elevated N/L ratio would be a predictor of development of significant ventricular arrhythmias in subjects undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS: We retrieved the data for all patients developing ventricular arrhythmia during PCI between 1999 to 2009 from our cath lab database (from 30,798 records), a total of 70 patients (Group I), and tabulated their WBC counts and absolute neutrophil and lymphocyte counts as well as N/L ratios. We compared the data with a random group of age, gender, medications and pre-existing condition matched controls (n=70) (Group II). We also adjusted for amount of myocardium under jeopardy. Group I had a significantly higher total WBC count (means 14,344 Vs 6852; 95% CI; p=0.0004); neutrophil count (means 75.79% Vs 58.06%; 95% CI; p < 0.0001) and N/L ratio (means 3.79 Vs 1.56; 95% CI; p < 0.0001) [means compared with t test]. CONCLUSION: Our data suggests a pre-procedural elevated WBC count, neutrophils and elevated N/L ratio are predictors of significant ventricular arrhythmias in patients undergoing percutaneous coronary intervention (PCI).
