Perfectionism in sports has been shown to predict longitudinal changes in athlete burnout. What mediates these changes over time, however, is still unclear. Adopting a self-determination theory perspective and using a three-wave longitudinal design, the current study examined perfectionistic strivings, perfectionistic concerns, autonomous motivation, controlled motivation, and athlete burnout i...
In 1949 William Evans gave the name of familial cardiomegaly to what he believed to be a "distinct syndrome having a definite clinical, cardiographic, and pathological pattern." The essential features were the familial incidence of cardiomegaly without obvious cause and a marked tendency to arrhythmia and heart block with associated palpitation, giddiness, and syncope. Death may be sudden or ra...
a 28-year-old man presented with a chest radiograph strongly suggestive for cardiomegaly. although he did not consent any hemodynamic studies, cardiomegaly was ruled out on the basis of the clinical course. computed tomography showed the existence of a large mass in both sides of the heart and in both lower hemithoraces. the tumor was resected by anterior mediastinotomy; it was weighted 2100 g ...
AMONG CAUSES of cardiac enlargement Of obscure origin that confront the clinician and pathologist alike are subendocardial fibroelastosis, inflammatory myocardiopathies, glycogen-storage disease, amyloidosis, muscular subaortic stenosis,' asymmetrical hypertrophy of the heart,2 idiopathic myocardiopathy,3 and familial cardiomegaly. Familial cardiomegaly, originally named in 1949 by Evans,4 has ...
The term "cardiomegaly" is found in 5-7% of chest X-ray film evaluations in tropical Africa. However, "cardiomegaly" is a descriptive term, devoid of any aetiological meaning. Therefore, providing information about the aetiological factors leading to heart enlargement in a group of Africans (Nigerians) was the purpose of this study. In the years 2002-2011, 170 subjects (aged 17-80 years, mean a...
Perfectionism in sports has been shown to be associated with burnout in athletes. Whether perfectionism predicts longitudinal changes in athlete burnout, however, is still unclear. Using a two-wave cross-lagged panel design, the current study examined perfectionistic strivings, perfectionistic concerns, and athlete burnout in 101 junior athletes (mean age 17.7 years) over 3 months of active tra...
Background and Objective: COVID-19 was first seen in Wuhan-China in December 2019, and became a widely- spreadepidemic and caused a terrifying life-threatening problem in most societies of the world. In Iran, a declaration was made on January 20, 2020, and all health systems were alerted of the disease threats. Materials and Methods: We collected all chest CT scans of 200 cases diagnosed as C...
