Intra-oral radiographs of 59 primary teeth were examined to judge the resorption of the mesial and distal roots, and were measured to record infra-occlusion of the primary teeth and tipping of the adjacent permanent teeth. The study comm...
Sports and energy (S/E) drinks are commonly used by high school (HS) athletes, yet little is known about this population’s consumption patterns or the drinks’ side-effects. The objectives of this pilot study were to survey HS athletes about their use of S/E drinks and assess potential side-effects. One hundred American HS athletes (72 were female; 27 were male; one did not identify gender) were...
UNLABELLED Cannabis use is associated with an earlier age of onset of psychosis (AOP). However, the reasons for this remain debated. METHODS We applied a Cox proportional hazards model to 410 first-episode psychosis patients to investigate the association between gender, patterns of cannabis use, and AOP. RESULTS Patients with a history of cannabis use presented with their first episode of ...
Purpose: A theory states that strong core stability allows athletes to fully transfer forces from the upper extremities to lower extremities, and finally to the ground. On the contrary, weak core stability causes alterations in transferring forces, reduces sport performance, and increases risk for injury, especially in the lower extremities. Therefore, the current study investigated the relatio...
OBJECTIVES Sustained aerobic dynamic exercise is beneficial in preventing cardiovascular disease. The effect of lifelong endurance exercise on cardiac structure and function is less well documented, however. A 12 year follow up of 20 veteran athletes was performed, as longitudinal studies in such cohorts are rare. METHODS Routine echocardiography was repeated as was resting, exercise, and 24 ...
BACKGROUND Right atrial (RA) size is important in screening, diagnosis, and follow-up assessment in patients with pulmonary hypertension. The objective of this study was to define normal reference values for RA area by echocardiography in a large population of athletic versus sedentary healthy subjects. METHODS AND RESULTS In the first part of the study, 880 healthy adult subjects (mean age, ...
BACKGROUND Lateral ankle sprains (LAS) are among the most common sports- related injuries and the reinjury rate is very high. OBJECTIVES This study aimed to evaluate the prevalence of some intrinsic risk factors among professional football and basketball players with or without history of acute or recurrent ankle sprain.

In this issue of the Journal, Corrado et al. (1) have described a prospective cohort study conducted in Veneto Region of Italy from 1979 to 1999 comparing sudden death (SD) in competitive athletes versus non-athletes in the range of 12 to 35 years of age. The study was well powered at approximately 29,000,000 person-years. The prospective cohort design was also optimal in addressing the study q...
Objective: Balance is the most basic function of the neuromuscular system in performing all simple and complex activities that contribute to health-related physical fitness. Musculoskeletal deformity especially, genu varum in the Lower extremity abnormality has negative effect on body biomechanics in walking and running. The aim of this study was to the comparison of balance between 1...
background: silicosis is known in industrial workers for centuries. till recently, the mainstay of its diagnosis and progress was clinical examination of the respiratory system, pulmonary function test and chest radiography. several biomarkers such as serum angiotensin converting enzyme (ace) activity have been examined to determine the extent of silicosis. objective: to elucidate the effect of...
