Tinnitus mostly results from central and peripheral auditory pathology. Chronic kidney disease (CKD) is a major risk factor for cerebrovascular disease. However, no studies have evaluated the association between tinnitus and CKD. The aim of this study is to investigate the risk of tinnitus in patients with CKD. This retrospective cohort study was conducted using Taiwan National Health Insurance Research Database from 2000 to 2010. We established a CKD group (n = 185,430) and a non-CKD comparison group (n = 556,290) to investigate the incidence of tinnitus...

Heart failure is a prevalent, progressive chronic disease costing in excess of $1billion per year in Australia alone. Disease self-management has positive implications for the patient and decreases healthcare usage. However, adherence to recommended guidelines is challenging and existing literature reports sub-optimal adherence. mHealth applications in chronic disease education have the potential to facilitate patient enablement for disease self-management. To the best of our knowledge no heart failure self-management application is available for safe use by our patients...

PURPOSE: Vitamin D is principally known for its role in calcium homeostasis, but preclinical studies implicate multiple pathways through which vitamin D may affect cardiovascular function and influence risk for heart failure. Many adults with cardiovascular disease have low vitamin D status, making it a potential therapeutic target. We review the rationale and potential role of vitamin D supplementation in the prevention and treatment of chronic heart failure. RECENT FINDINGS: Substantial observational evidence has associated low vitamin D status with the risk of heart failure, ventricular remodeling, and clinical outcomes in heart failure, including mortality...

BACKGROUND: Heart transplantation (HTx) is the preferred treatment for patients with end-stage heart failure and has been successful for >30 y. The clinical course of recipients at the extreme of age is unknown. We reviewed our experience to determine the overall health and prevalence of Tx-related medical problems for recipients in their ninth decade. METHODS: We reviewed the UCTP experience from 1985 to present to identify patients who survived into their 80s and matched (1:1) with other recipients for gender and age at HTx, but did not survive to ≥80 y...

Chronic hypocalcemia, irrespectively of its etiology, can lead to severe impairment of the left ventricular (LV) contractility manifesting as dilated cardiomyopathy, usually defined as hypocalcemic cardiomyopathy (hypocaCM). This rarely diagnosed type of heart failure (HF), can be completely reversible, when treated properly with calcium and vitamin D supplementation or, in some subjects, with human recombinant parathormone. A CASE REPORT: The authors present a case of a 60-year-old male admitted with advanced pulmonary congestion, recurrent pulmonary edema and pleural effusion...

INTRODUCTION: Clinical onset of chronic obstructive pulmonary disease (COPD) is the point at which the disease is first identifiable by physicians. It is a poorly defined stage which seems to include both mild spirometric and non-spirometric disease, and could be described as early grade COPD, for practical purposes. While dyspnoea; chronic bronchitis and CT imaging evidence of emphysema and airway disease may be present very early, the lone significance of dyspnoea, the most relevant symptom in COPD in identifying these individuals, has been scarcely assessed...

BACKGROUND: Our aim was to develop a model of acute right heart failure (ARHF) in the setting of pulmonary hypertension and to characterize acute right ventricular lesions that develop early after hemodynamic restoration. METHODS AND RESULTS: We used a described piglet model of chronic pulmonary hypertension (cPH) induced by pulmonary artery occlusions. We induced ARHF in animals with cPH (ARHF-cPH group, n=9) by volume loading and iterative acute pulmonary embolisms until hemodynamic compromise followed by dobutamine infusion for hemodynamic restoration prior to sacrifice for right ventricular tissue evaluation...

OBJECTIVE: For chronic heart failure (CHF), more emphasis has been placed on evaluation of systolic as opposed to diastolic function. Within the study of diastology, measurements of left ventricular (LV) longitudinal myocardial relaxation have the most validation. Anterior wall radial myocardial tissue relaxation velocities along with mitral valve inflow (MVI) patterns are applicable diastolic parameters in the differentiation between moderate and severe disease in the ischemic rat model of CHF...

Fatigue is a symptom experienced almost universally by people living with a chronic illness. People diagnosed with heart failure have described experiencing significant levels of fatigue. The family experience of fatigue, that is, how families perceive, respond to, and manage fatigue, is unknown. Semistructured family group interviews with 22 families ( N = 62 family members) were conducted. Thematic analysis was undertaken to explore the family experience of fatigue. Fatigue was described as a significant symptom that affected physical, emotional, and social functioning at a family level...
