Chronic obstructive pulmonary disease (COPD) is associated with a 3.9% reduction in workforce participation rates, particularly among those with moderate to severe disease. Additionally, sleep-disordered breathing in mildly obese men is linked to glucose intolerance and insulin resistance.
A new study reveals a strong link between children's sleep problems and behavioral issues like hyperactivity and inattention. The research, published in the journal Pediatrics, found that children who snore often are nearly twice as likely to have attention and hyperactivity problems.
Patients treated with nocturnal breathing support for sleep apnoea experience a significant reduction in blood pressure, as well as improved quality of life and reduced excessive daytime sleepiness. The study confirms that therapeutic nCPAP treatment produces a clinically important lowering of blood pressure.
The study investigated LTF in OSA patients with hypoxic exposure using nasal CPAP. Hypoxia caused increased minute ventilation and decreased upper airway resistance, which persisted during the recovery period.
Researchers found that men exhibited a decrease in coordination during exercise-induced hypoxia, whereas women showed an increase. Conversely, women had lower ventilatory responses to hypoxia compared to men.
Researchers identified a small group of neurons responsible for issuing breathing commands within the preBotzinger Complex. Destroying these neurons in rats resulted in irregular breathing patterns and impaired oxygen control, suggesting they hold underlying causes of breathing disorders.
Respiratory sounds can precisely determine the level of shortness of breath in asthma patients. A new computer program uses acoustic analysis to detect breathing problems, potentially setting off an alarm during sleep and enabling researchers to study conditions without inducing symptoms.

A study found that using oral steroids to control severe asthma attacks reduced the risk of death from the disease by 90 percent. A written asthma action plan also significantly reduced the risk of death and hospitalization rates. Additionally, African-American women experienced a slower rate of lung function decline with age compared ...
Researchers found that obese individuals were twice as likely to be diagnosed with asthma, but not more responsive airways. Underweight individuals, on the other hand, experienced increased airway responsiveness and reduced lung function.
A pilot study found that an implanted 'brain pacemaker' for epilepsy may cause mild increases in sleep apnea, a condition where breathing is disrupted during sleep. Researchers are investigating ways to fine-tune the device to reduce these effects and improve treatment outcomes.
A large-scale survey of over 65,000 people in Norway found that women are more susceptible to the damaging effects of cigarette smoke. Women reported higher rates of respiratory symptoms and asthma compared to men, particularly among those who smoked more cigarettes daily.
Studies at the University of Illinois have identified a brain pathway in which neurons activate during low oxygen, triggering increased breathing. Newborns may not have enough neurons to respond sufficiently, possibly contributing to sudden infant death syndrome.
The Respiratory Tract Infection Alert, a first national tracking system, provides predictive information via the Internet and a toll-free number to predict RTI season peaks. The system tracks common respiratory tract infections such as bronchitis, sinusitis, and pneumonia.
A new clinical score for managing upper respiratory tract infections with sore throat could substantially reduce unnecessary antibiotic prescriptions. The study found that using the score would have reduced antibiotics prescribed to culture-negative patients by 63.7% and overall antibiotics by 52.3%.
A comparative study found Factive eradicated H. influenzae after one day, while Biaxin took seven days. The results showed Factive's superior efficacy in treating chronic bronchitis airway infections.
A 2-year study found that day care centers incubate and spread antibiotic-resistant respiratory tract bacteria, including Streptococcus pneumoniae. The study suggests that day care centers are ideal environments for the development of such resistance due to high rates of respiratory infections and antibiotic use.
The European Respiratory Society warns that hundreds of medicines can cause lung diseases, with 310 therapeutic substances identified as having iatrogenic effects. Early withdrawal of these medicines can reduce the risk of damaging sequelae in 70% of cases.
A health survey of Hong Kong police officers found that longer exposure to passive smoking was associated with more time off work, doctor visits, and medication use. Non-smoking men exposed for over a year were twice as likely to take time off and 30% more likely to have respiratory symptoms.
A five-year study found that people who snore are one and a half times more likely to have high blood pressure, with risk increasing with severity of sleep problem. The study suggests that physicians should consider hypertension when SDB is present.
A University of Michigan study suggests that patients with undiagnosed sleep apnea may not always describe their symptoms as 'sleepy', but rather experience fatigue, tiredness, or lack of energy. Laboratory sleep tests revealed interrupted breathing patterns in 73% of the study's subjects.
Researchers developed a computer-controlled flow delivery device that monitors tracheal pressure and varies the flow of air to prevent apnea. The new technology may lead to alternative treatments for severely affected patients, potentially reducing the need for tracheotomies.
Two studies found a decrease in respiratory illnesses among school-age children after improved air quality. Lung function continued to grow in adolescents despite cessation of growth in height, with males showing greater gains. A new diagnostic test for asthma in young children was also developed.
A nationwide clinical trial found that reducing tidal volumes in mechanical ventilation can cut mortality from Acute Respiratory Distress Syndrome (ARDS) by up to 22%. The study, involving 861 patients and coordinated at Massachusetts General Hospital, used a new technique with smaller oxygen puffs to provide breathing assistance.
A new medical test using pulse oximetry can accurately diagnose obstructive sleep apnea in children, reducing equipment and staffing costs. The test also enables early treatment for children with breathing obstruction related to tonsils or adenoids, improving respiratory health outcomes.
A study of 1050 men and 1098 women in Spain found that 26.2% of men and 28% of women experienced abnormal breathing during sleep, considered a threshold for obstructive sleep apnea (OSA). OSA is linked to increased risk of cardiovascular diseases and daytime drowsiness.
A new Mayo Clinic study confirms that bed partners experience significant improvements in sleep quality when their husbands are treated for obstructive sleep apnea. The average percentage of time spent sleeping increases from 74% to 87%, adding over an extra hour of sleep per night.
The 9th annual meeting of the European Respiratory Society will address various topics such as lung cancer, asthma, chronic bronchitis, and sleep apnea. The congress will also feature discussions on artificial ventilation methods, non-invasive ventilation, and respiratory problems faced by mountaineers, deepsea divers, and astronauts.
A recent University of Iowa Health Care study found that genetic factors and sex differences significantly affect human responses to endotoxin, with women more likely to experience declined airway function. The study examined 72 individuals without respiratory conditions and discovered a wide range of reactions to the contaminant.
Researchers have found that tiny air pollutant particles can penetrate deeper into the lungs of healthy adults, potentially threatening their health. The study suggests that these particles can move up to two times faster through the airways than previously assumed, with implications for public health and environmental regulations.
A new report reveals that many heroin overdose deaths can be prevented with prompt medical attention and treatment. The study highlights the effectiveness of methadone maintenance programs in reducing overdose-related deaths. By increasing access to these programs, the US can combat its heroin epidemic.
A new study by researchers at UCSF found that bartenders who worked in smoke-free conditions after the ban reported significant drops in coughing and other respiratory problems. Lung function also improved after the implementation of the smoke-free workplace law.
A recent study found that bartenders' respiratory health and lung function improved significantly after a smoke-free environment was established in California bars. The study, supported by the National Heart, Lung, and Blood Institute, suggests that banning smoking in bars can have a positive impact on the health of bartending staff.
A new study found that children retain more simulated air pollution per unit of lung surface area than adults, suggesting they are more susceptible to illnesses caused by polluted air. Researchers will extend their studies to exercising volunteers to further understand the effects of particulate air pollution on children.
A study of 1235 adults found that obesity was associated with reduced breathing capacity, but only when fat mass was present. Handgrip strength and muscular fitness were also linked to improved lung function, suggesting a mediating role in the relationship between body composition and respiratory function.
A new study by exercise science researchers at the University at Buffalo found that wearing nasal strips has no effect on breathing during intense exercise. The strips may still be beneficial for individuals with exercise-induced asthma, however.
A study by the American Heart Association found that casinos and airplanes are more likely to have automated external defibrillators (AEDs) than primary-care physicians' offices. The devices were found on firetrucks, police cars, and in some airlines, but only six out of 51 offices had a defibrillator.
Researchers found a causal relationship between sleep-disordered breathing and hypertension in a substantial number of American adults. People with mild to moderate sleep apnea were 1.8 times more likely to have hypertension than those without, with the severity of apnea linked to increased blood pressure risk.
