The classic stethoscope has entered the digital age. Medical researchers have created a computer program that connects to an electronic stethoscope to classify lung sounds into five common diagnostic categories, with a high sensitivity for lung sounds, advancing diagnosis accuracy.
Patients with COPD demonstrated gray matter decreases in areas of the brain that process breathlessness, fear and sensitivity to pain. The study found patients with COPD show regionally decreased gray matter volume in the anterior, mid, and posterior cingulate cortex, hippocampus, and amygdala. Levels of degeneration in certain areas of the brain were also impacted by longer disease duration. Those individuals showed a greater fear of breathlessness and fear of physical activity, which can affect the course of the disease.
The key to an inherited deficiency, predisposing people to emphysema and other lung conditions, could lie in their Viking roots. Archaeological excavations of Viking latrine pits in Denmark have revealed that these populations suffered massive worm infestations. The way that their genes developed to protect their vital organs from disease caused by worms has become the inherited trait which can now lead to lung disease in smokers.
The prevalence of past-year generalized anxiety disorder (GAD) for adults aged 50 and older with chronic obstructive pulmonary disease (COPD) is much higher compared to older adults without COPD (5.8 percent vs 1.7 percent), according to a new study.
Among mechanically ventilated patients with chronic obstructive pulmonary disease (COPD) and metabolic alkalosis, administration of the respiratory stimulant acetazolamide did not significantly reduce the duration of invasive mechanical ventilation, according to a study.
