Epidemiology, genetics, and subtyping of preserved ratio impaired spirometry (PRISm) in COPDGene. [PDF]

, 2014
BackgroundPreserved Ratio Impaired Spirometry (PRISm), defined as a reduced FEV1 in the setting of a preserved FEV1/FVC ratio, is highly prevalent and is associated with increased respiratory symptoms, systemic inflammation, and mortality.

Intermittent Recurrence of Ureterosciatic Hernia After Spontaneous Resolution, Complicated by Emphysematous Pyelonephritis

IJU Case Reports, EarlyView.
ABSTRACT Introduction Ureterosciatic hernia is a rare condition in which the ureter herniates through the sciatic foramen, causing ureteral obstruction, and urinary infection. Case Presentation A 72‐year‐old woman presented with left flank pain. Computed tomography revealed left hydronephrosis with ureterosciatic hernia.

Exercise intolerance and systemic manifestations of pulmonary emphysema in a mouse model

Respiratory Research, 2009
Background Systemic effects of chronic obstructive pulmonary disease (COPD) significantly contribute to severity and mortality of the disease. We aimed to develop a COPD/emphysema model exhibiting systemic manifestations of the disease.

Roles of mitochondrial ROS and NLRP3 inflammasome in multiple ozone-induced lung inflammation and emphysema

Respiratory Research, 2018
BackgroundMitochondrial damage leading to oxidant stress may play an important role in the pathogenesis of airflow obstruction and emphysema. NLPR3 inflammasome can be activated by mitochondrial ROS (mtROS) and other stimuli.

Hepatocyte and keratinocyte growth factors and their receptors in human lung emphysema

BMC Pulmonary Medicine, 2005
Background Hepatocyte and keratinocyte growth factors are key growth factors in the process of alveolar repair. We hypothesized that excessive alveolar destruction observed in lung emphysema involves impaired expression of hepatocyte and keratinocyte ...

Dose‐dependent association of systemic comorbidities with periodontitis severity: A large population cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background To examine whether the associations between periodontitis and multiple systemic conditions increase with increasing severity of periodontitis using a multi‐center electronic health record (EHR) repository. Methods A cross‐sectional analysis was conducted using EHR data from 9 dental schools in the United States.

Lung volumes identify an at-risk group in persons with prolonged secondhand tobacco smoke exposure but without overt airflow obstruction. [PDF]

, 2018
IntroductionExposure to secondhand smoke (SHS) is associated with occult obstructive lung disease as evident by abnormal airflow indices representing small airway disease despite having preserved spirometry (normal forced expiratory volume in 1 s-to ...

Impact of Environmental and Seasonal Factors on Spontaneous Pneumomediastinum With and Without Pneumorrhachis

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Spontaneous pneumomediastinum (SPM) with pneumorrhachis is rare but generally benign and self‐limiting. However, the impact of environmental and seasonal factors on SPM remains unclear. This study investigated their association with SPM onset and clinical outcomes.

Characteristics of the elderly in high - resolution computed tomography lung densitometry [PDF]

, 2004
To determine the characteristics of the elderly in high - resolution computed tomography (HRCT) lung densitometry, mean lung density (MLD) and relative area of the lungs showing attenuation values less than -950 HU (RA(950)) on HRCT were evaluated in ...
