The new ATS ERS guidelines for assessing the spirometric severity of restrictive lung disease differ from previous standards

Volume 12 Issue 5 Page 759-762, September 2007doi:10.1111/j.1440-1843.2007.01117.x

The ATS/ERS Task Force on Lung Function Testing recently proposed guidelines for the interpretation of pulmonary function tests and suggested that a reduction in FEV1 be used for categorizing both obstructive and restrictive abnormalities. This changes the severity stratification algorithm of restrictive patterns diagnosed by spirometry, that are currently categorized based on reduction in VC. This study examined the level of agreement between these two categorization schemes.

Circadian rhythms and sleep related breathing disorders

Volume 8, Issue 6, Pages 681-687 (September 2007)

Recent studies have provided evidence that the human circadian timing system has an influence on respiration and respiratory control. Both sleep and circadian mechanisms combine to mediate the rise in lower airway resistance in nocturnal asthma. In rats, circadian rhythms in minute ventilation are present in both wakefulness and sleep, implying that circadian and sleep mechanisms also combine to influence the control of breathing.

Haemodialysis patients with sleep apnoea syndrome experience increased central adiposity and altered muscular composition and functionality

Nephrology Dialysis Transplantation, doi:10.1093

Sleep apnoea frequently affects patients with end-stage renal disease. However, it is still unclear whether or to what extent sleep disorders may affect functional capacity and quality of life in haemodialysis patients. We tested the hypothesis that apneic dialysis patients due to the lack of restorative sleep will have a further reduced functional capacity and further compromised quality of life compared to their non-apneic counterparts.


09/27/2007 02:12 PM

Apnea Patients at Higher Risk for Cardiovascular Disease

Emergency Medicine News:Volume 29(7)July 2007p 12

Researchers have found that patients with obstructive sleep apnea have higher levels of apoptotic cells from the endothelium of their blood vessels circulating in their bloodstream than people who do not have obstructive sleep apnea, which may explain why those with apnea are at higher risk for cardiovascular disease. The findings appear in the June 1 issue of the American Journal of Respiratory and Critical Care Medicine.

Value of ischemia modified albumin in the diagnosis of pulmonary embolism

The American Journal of Emergency Medicine, Volume 25, Issue 7, Pages 770-773

Pulmonary embolism (PE) is a common condition, but the diagnostic strategy for the evaluation of suspected PE is somewhat controversial. Despite the use of various biochemical markers (such as D-dimer and C-reactive protein) and various probability calculation algorithms based on clinical findings for that purpose, there is still a need for more specific and practical markers in PE diagnosis. The aim of this study was to investigate the diagnostic value of ischemia-modified albumin (IMA) levels in the diagnosis of PE.

Short Term Cigarette Smoke Exposure Predisposes the Lung to Secondary Injury

Lung Volume 185, Number 4 / August, 2007 227-233

Brief exposure to cigarette smoke is not generally associated with pulmonary injury and may adversely affect the lung only if underlying disease is present. To test this hypothesis, our laboratory performed a series of experiments involving exposure of hamsters to second-hand cigarette smoke (2 h/day for 5 days), either immediately before or after induction of acute pulmonary injury by intratracheal administration of amiodarone.

The Development of Asthma In Wheezing Infants with Chlamydia pneumoniae Infection

Journal of Asthma, Volume 44, Issue 7 September 2007 , pages 565 - 568

Chlamydia pneumoniae infection might play a role in the pathology of asthma, but its role in infantile asthma remains obscure. The presence of Chlamydia pneumoniae was serologically determined in wheezing infants who were then re-examined 1-year later to determine whether or not asthma is associated with this type of infection. Wheezing infants progressed to asthma more frequently after infection with Chlamydia pneumoniae than those who were not infected. These findings suggested that Chlamydia pneumoniae infection triggers asthma in wheezy infants.

Inverse association of plasma IL 13 and inflammatory chemokines with lung function impairment in stable COPD a cross sectional cohort study

Respiratory Research 2007, 8:64

Chronic obstructive pulmonary disease (COPD) is a heterogeneous syndrome characterized by varying degrees of airflow limitation and diffusion impairment. There is increasing evidence to suggest that COPD is also characterized by systemic inflammation. The primary goal of this study was to identify soluble proteins in plasma that associate with the severity of airflow limitation in a COPD cohort with stable disease. A secondary goal was to assess whether unique markers associate with diffusion impairment, based on diffusion capacity of carbon monoxide (DLCO), independent of the forced expiratory volume in 1 second (FEV1).
