background: postoperative cognitive dysfunction (pocd) has been an important complication of cardiac surgery over the years. neurocognitive dysfunction can affect quality of life and lead to social, functional, emotional, and financial problems in the patient’s life. to reduce pocd, we sought to identify the association between cognitive dysfunction and perioperative factors in patients undergo...

chronic obstructive pulmonary disease (copd) is associated with a chronic inflammatory response in airways and lung parenchyma that results in significant morbidity and mortality worldwide. cigarette smoking considered as an important risk factor plays a role in pathogenesis of disease. pneumocystis jirovecii is an atypical opportunistic fungus that causes pneumonia in immunosuppressed host, al...

background: chronic obstructive pulmonary diseases (copd) are planned to rank fifth in burden of disease and third with respect to mortality by 2020. carrying out research regarding different aspects of copd is mentioned as important health priorities by academic institutions and governments. the burden of lung disease (bold) initiative was designed a decade ago to develop robust models that ca...

You visit Mr K. and his family in the hospital ...

background and purpose: chronic obstructive pulmonary disease (copd) has been recognized as a risk factor for invasive aspergillosis. airway colonization by aspergillus species is a common feature of chronic pulmonary diseases. nowadays, the incidence of copd has increased in critically ill patients. the aim of the present study was to isolate and identify aspergillus colonies in the respirator...

conclusions we found statistical differences in pct levels that would differentiate cap from acute exacerbation of copd in the ed setting. further studies are required to verify this finding. methods this cross-sectional prospective descriptive study was performed in the emergency department (ed) on patients with cap and acute exacerbation of copd. a total of 53 patients were included in this s...

introduction: corticosteroids are routinely used in management of chronic obstructive pulmonary disease (copd) exacerbation. the main purpose of present study was to compare the efficacy of methyl prednisolone (mp) and dexamethasone (dxm) for this purpose. methods: adult copd patients entered the present clinical trial. all patients received standard treatment on admission and were then divided...

background: depression and smoking decrease health status in chronic obstructive pulmonary disease (copd), but the combined effect of the two factors is unknown. this study aimed to assess the interactive effects of depression and smoking on the severity of patients with copd. methods: a prospective cohort study including 2,268 patients with copd was conducted in seven rural communities from ma...

abstract   background: chronic obstructive pulmonary disease (copd) is a major cause of morbidity and mortality, and is an important health economic problem. since 1960, there has been an increase in mortality associated with copd, especially in men. acute exacerbations form a major component of the socioeconomic burden of copd which mainly results in long-term hospitalization. despite the high...

introduction: pulmonary hyperinflation in patients with chronic obstructive pulmonary disease (copd) can increase the breathing rate and reduce diaphragmatic movements by pushing the diaphragms downward and limiting their movements; this, in fact, can affect the breathing process. the purpose of this study was to compare diaphragmatic movements in copd patients and healthy ones and to evaluate ...
