Diaphragm Atrophy Occurs Within Two Weeks Of Mechanical Ventilation

Ventilated, acutely critically ill patients may experience significant diaphragmatic atrophy within the first two weeks of mechanical ventilation, according to a new Mt. Sinai School of Medicine study. Researchers used bedside ultrasound and charts to determine the diaphragm thickness of 20 intensive care unit (ICU) patients, within 48 hours of intubation. Weekly follow-up images were obtained until patients were either removed from the ventilator or died. [click link for full article]

Sildenafil May Improve Daily Activities In COPD

Patients who suffer from COPD may benefit from agents, such as sildenafil, that cause vasodilation, according to researchers from the Netherlands. The new study investigated the acute effects of sildenafil on patients with COPD both at rest and during exercise. The response was also tested on patients with COPD both with and without pulmonary hypertension (PH), which is a common complication of COPD. [click link for full article]

COPD Progression More Rapid In Smokers

Patients with COPD, who continue to smoke, have the worst disease prognosis, according to a new study. Researchers from Illinois and Massachusetts collected the pyrometer data of 538 participants from the Framingham Heart Study. The participants were categorized according to Global Initiative for Obstructive Lung Disease (GOLD) stages at the beginning and end of 12 years, and smoking status, age, and gender were used to estimate disease progression.

COPD Underdiagnosed And Undertreated In Smokers

A new study suggests clinicians should be more aware of possible COPD in patients at risk for lung cancer. Researchers from the University of Alabama obtained the demographic, medical, and spirometric information of 449 subjects who smoked and were enrolled in the National Lung Screening Trial. Subjects were classified into Global Initiative for Obstructive Lung Disease (GOLD) stages, and those who had a diagnosis of COPD and were treated. [click link for full article]

Hyperglycemia In COPD May Lead To Longer Hospital Stays

Patients hospitalized with COPD and asthma exacerbations are likely to have poor glucose control and an associated increased length of stay (LOS) in the hospital, according to a study from Cooper University Hospital. Sixty-seven patients hospitalized for COPD or asthma exacerbations were evaluated for hyperglycemia and a correlation with LOS during corticosteroid treatment. Researchers assessed demographic data, corticosteroid dose and duration, glucose levels, and management. [click link for full article]

Vitamin C May Aid In COPD/Pneumonia Prognosis

During exacerbation, vitamin C is markedly decreased in inflammatory diseases, such as acute pneumonia and COPD, according to a new study. Serbian researchers compared the values of serum ascorbate concentration and laboratory inflammation indicators in 60 nonsmoking patients. The patients were split into three groups: 20 patients with acute pneumonia (group I), 20 patients with stable COPD (group II), and 20 patients with exacerbated COPD (group III).

Prolonged Ventilation In Muscular Dystrophy Increases Complications

New research from MetroHealth Medical Center in Ohio suggests that patients with Duchenne muscular dystrophy experience a higher incidence of noncardiopulmonary complications when prolonged survival involved assisted ventilation. Researchers conducted a retrospective chart review of 27 patients with DMD who were 20-years-old or older. [click link for full article]

Diabetes Increases Asthma Prevalence

A new study reveals that the prevalence of asthma is significantly higher in patients with type II diabetes mellitus (DM), independent of other comorbid conditions. California researchers reviewed data from 293,124 patients with DM and 552,623 patients with hypertension but no DM (control group). Using multivariate analysis, researchers found that DM remained independently associated with asthma, which was present in 4.5 percent of patients with DM vs 2.9 percent of controls.

Job Safety Education Can Reduce Respiratory Symptoms

Professional cleaners who do not receive or understand workplace safety education are more likely to experience occupational asthma, according to a new study. Canadian researches preformed a work-place safety survey of 566 professional cleaners. Subjects were surveyed about asthma history and their degree of safety training comprehension. Among those surveyed, 94 percent reported receiving training, and 13 percent reported having difficulty understanding the topics. [click link for full article]

New Surgery For Asthma Improves Symptoms

A new surgical procedure that reduces the amount of a person's airway smooth muscle has the potential to decrease asthma symptoms caused by bronchoconstricition, according to a new study. Researchers from Canada conducted a randomized, multicenter study to examine the effect of bronchial thermoplasty on patients with moderate-to-severe, persistent asthma. A total of 108 subjects were enrolled and received standard medical management and bronchial thermoplasty. [click link for full article]
