background and aims: the aim of this study was the modeling of the incidence rates of colorectal, breast and prostate cancers using a shared component model in order to explore the spatial pattern of their shared risk factors (i.e., obesity and low physical activity) affecting on cancer incidence, and also to estimate the relative weight of these shared components. methods: in this study, the ...

nocturnal oxygen desaturation using pulse oximeter and apnomonitor in patients with chronic pulmonary disease. Why are patients with chronic obstructive pulmonary disease at increased risk of cardiovascular dis-eases? The potential role of systemic inflammation in chronic obstructive pulmonary disease. W hile health-related problems have a definite and identifiable effect on patients, the patie...

the objective of this study was to investigate the validity and reliability of the farsi version of the perceived benefits/barriers scale of physical activity in iranian elderly.overall, 388 elderly subjects (60 yr and over) completed the demographic characteristics questionnaire, the exercise benefits/barriers scale (ebbs) and the yale physical activity scale. data were analyzed through of exp...

Outcome assessment in patients with rheumatoid arthritis (RA) includes measurement of physical function. We derived a scale to quantify global physical function in RA, using three performance-based rheumatology function tests (RFTs). We measured grip strength, walking velocity, and shirt button speed in consecutive RA patients attending scheduled appointments at six rheumatology clinics, repeat...

We present a new ion kinetic model describing the ignition and burn of the deuterium-tritium fuel of inertial fusion targets. The analysis of the underlying physical model enables us to develop efficient numerical methods to simulate the creation, transport and collisional relaxation of fusion reaction products (α-particles) at a kinetic level. A two-energy-scale approach provides a framework f...

background: fatigue, depression, and physical impairment are common  among  multiple  sclerosis (ms) patients. the aim  of  this  study was to  determine  the   relationship between depression,  physical impairment,  and  fatigue  in an iranian ms cohort. methods: fifty consecutive  relapsing-remitting ms patients and  50 age- and  sex-matched healthy  controls (hcs) were recruited  from sina r...

This paper surveys recent research on the use of sensor networks, communications and computer systems to enhance the human outcome of emergency situations. Areas covered include sensing, communication with evacuees and emergency personnel, path finding algorithms for safe evacuation, simulation and prediction, and decision tools. The systems being considered are a special instance of real-time ...

Background: Increasingly randomized controlled trials in cancer research include Health-Related Quality of Life (HRQoL) alongside traditional biomedical outcome measures. The majority of these trials focus on a general cancer HRQoL measure. The objective of this meta-analysis was to identify which HRQoL indicators influence a patient’s overall quality of life, in order to better understand the ...
