Vitamin D Failed to Stop COVID, Other Respiratory Infections
Vitamin D supplements did not ward off COVID-19 or other respiratory infections, two randomized controlled trials showed. Among 6,200 participants in a phase III study from the U.K., 2.6% of those in the control group developed COVID-19 compared with 3.6% of those who received 800 IU vitamin D daily (OR 1.39, 95% CI 0.98-1.97) and […]
Dual Bronchodilators No Help for Symptomatic Smokers With Preserved Lung Function
Inhaled dual bronchodilator therapy did not decrease respiratory symptoms in former or current smokers with preserved lung function, the RETHINC trial showed. Among 535 symptomatic smokers with a 10 pack-year history and preserved lung function assessed by spirometry, 56.4% in the treatment group and 59.0% in the placebo group had a least a 4-point decrease […]
Less Invasive Surfactant Delivery Works for Tiniest Newborns
For extremely preterm infants with potential respiratory distress syndrome, less invasive surfactant administration (LISA) was associated with a significant decrease in the risk of adverse outcomes, a cohort study found. There was a drop in requirement for invasive mechanical ventilation between those infants receiving LISA within the first 72 hours of life and those who […]
Early Signs of Hantavirus, Treatment, Contagious, Prevention & Test
Symptoms of Hantavirus Flu-like Symptoms The flu (influenza) is a viral disease of the respiratory tract. Characteristic symptoms are fever, chills, cough, malaise, and headache. Other symptoms can occur, like nausea and vomiting, muscle or body aches, tiredness and fatigue, appetite loss, sore throat, and diarrhea. Read about other flu symptoms » What is hantavirus […]
Smaller Airways Set the Stage for Worse COPD Outcomes in Women
Smaller airways in women may explain their worse respiratory outcomes in chronic obstructive pulmonary disease (COPD), a large cohort study suggested. For never-smokers and ever-smokers alike, CT imaging revealed that men had thicker airway walls than women, who also had smaller airway lumen dimensions after accounting for height and total lung capacity. “It is plausible […]
Oral antiviral drug effective against respiratory syncytial virus (RSV)
An oral antiviral drug that targets a key part of the respiratory syncytial virus (RSV) polymerase and inhibits the synthesis of viral genetic material has been identified, a finding that could provide an effective treatment against RSV disease, according to researchers in the Center for Translational Antiviral Research at Georgia State University. The findings, published […]
Legionnaires’ Disease: Outbreak, Causes, Symptoms, Treatment & Prevention
Acute respiratory distress syndrome (ARDS) is a lung condition in which trauma to the lungs leads to inflammation of the lungs, accumulation of fluid in the alveolar air sacs, low blood oxygen, and respiratory distress. ARDS can be life-threatening. Signs and symptoms of are shortness of breath and low levels of oxygen in the blood, […]
Experts Predict If And When COVID Will Become A Seasonal Illness
The vast majority of respiratory viruses that spread within our population ebb and flow with the seasons. Influenza spikes in the winter months, as do infections caused by respiratory syncytial virus (RSV), adenoviruses and other coronaviruses. Earlier this year, Rochelle Walensky, the Centers for Disease Control and Prevention director, said she expects COVID to also […]
RSV Vaccine Holds Promise for Pregnant Women
A bivalent protein-based vaccine against respiratory syncytial virus (RSV) administered during pregnancy was safe and led to higher neutralizing antibody responses in mothers, as well as evidence of protection in their infants, an interim analysis of a phase IIb trial found. The geometric mean ratios of 50% neutralizing antibody titers against RSV A and B […]
Investigational RSV Vaccine in Pregnancy Tied to Fewer Abx Scripts for Babies
Infants whose mothers received an investigational respiratory syncytial virus (RSV) vaccine in pregnancy had fewer antimicrobial prescriptions during their first 3 months of life, a post hoc secondary analysis of a randomized trial found. Across 11 countries, infants born to mothers assigned to the vaccine arm during pregnancy had a 12.9% (95% CI 1.3-23.1) lower […]
