Smoking e-cigarettes, also called vaping, has been marketed as a safe alternative to tobacco cigarettes and is rising in popularity among non-smoking adolescents. However, a single e-cigarette can be harmful to the body’s blood vessels — even when the vapor is entirely nicotine-free — according to a new study by researchers in the Perelman School

Smoker’s cough is all too often trivialised 31. May is world tobacco day. To warn this occasion, an Austrian University before a deadly disease, COPD (Chronic obstructive pulmonary disease). An investigation revealed that the severity of lung disease plays in the public perception, even though COPD is the third leading cause of death is now

A KAIST research team succeeded in visualizing pulmonary microcirculation and circulating cells in vivo with a custom-built 3D intravital lung microscopic imaging system. They found a type of leukocyte called neutrophils aggregate inside the capillaries during sepsis-induced acute lung injury (ALI), leading to disturbances and dead space in blood microcirculation. According to the researchers, this

An estimated six to 15 million people in the U.S. are children born of a pregnancy complicated by preeclampsia. New research performed in rats reveals that treating preeclampsia with sildenafil citrate (Viagra) may help protect the cardiovascular health of the offspring. Preeclampsia occurs when women with otherwise normal blood pressure experience elevated blood pressure during

Specialized lung cells appear in the developing fetus much earlier than scientists previously thought. A new animal study reports how cells that become alveoli, the tiny compartments in which gas exchange occurs in the lung, begin their specialized roles very early in prenatal life. The researchers say that investigating the fetal signaling pathways active in

New Mexico contains hundreds of historic uranium mines. Although active uranium mining in the state has ceased, rates of cardiovascular and metabolic disease remain high in the population residing close to mines within the Navajo Nation. According to a new study in ACS’ journal Environmental Science & Technology Letters, inhaled uranium in dusts from the

A major compound in soil organic matter degrades chronic wasting disease prions and decreases infectivity in mice, according to a study published November 29 in the open-access journal PLOS Pathogens by Judd Aiken of the University of Alberta, and colleagues. Chronic wasting disease is an environmentally transmissible, fatal prion disease affecting free-ranging deer, moose, elk

The most common tests for glaucoma can underestimate the severity of the condition by not detecting the presence of central vision loss, according to a new Columbia University study. The study, published Nov. 8 in JAMA Ophthalmology, found that administering a variation of the visual field test that better assesses macular damage can improve diagnosis

Group A Streptococcus (GAS), sometimes known as “flesh-eating bacteria,” causes invasive infections that result in high mortality. GAS is susceptible to many antibiotics, but continues to cause devastating infections. Many studies have attempted to understand the mechanism for immune recognition of GAS; none has provided a clear explanation, until now. In a new study published

COPD is a collection of chronic lung disorders that usually develop after years of lung damage. Age does appear to be a factor with COPD because of this, and older people may be more at risk than those who are younger. Diagnosing COPD early is critical because treatment focuses on slowing the progression of the

Symptoms of COPD, such as wheezing, shortness of breath, and fatigue, can be similar to the signs of other lung conditions. COPD often gets progressively worse over time. Getting an accurate and early diagnosis allows doctors to develop an effective treatment plan that can help slow the progression of a person’s disease. Doctors begin diagnosing

Increasing physical activity in patients with chronic obstructive pulmonary disease (COPD) is a key strategy and a major challenge in the fight against this respiratory disorder. According to a study published in European Respiratory Journal, the urban training intervention for COPD patients designed by the Barcelona Institute for Global Health (ISGlobal) has proved efficacious in

(HealthDay)—The frequency of acute exacerbations of chronic obstructive pulmonary disease (AECOPDs) in a single year predicts the long-term rate of AECOPDs, according to a study recently published in the American Journal of Respiratory and Critical Care Medicine. Kieran J. Rothnie, Ph.D., from Imperial College London, and colleagues examined the natural history of AECOPDs among 99,574

Researchers report in Nature Communications they figured out why air sacs in the lungs clog up with a thick substance called surfactant in a brutal disease called Pulmonary Alveolar Proteinosis (PAP), and they show taking cholesterol-busting pills called statins can effectively treat the disease. That’s good news for people with PAP because at present the

MONDAY, July 2, 2018 — For patients with advanced chronic obstructive pulmonary disease (COPD), the use of formal palliative care services and long-term oxygen therapy has increased but remains low, according to a study published online June 11 in the American Journal of Respiratory and Critical Care Medicine. Andrea S. Gershon, M.D., from Sunnybrook Health

Scientists have found that it is the structure of collagen, rather than the amount, that leads to the devastating condition of lung fibrosis, according to a report in the journal eLife. The study provides the first evidence in humans that altered collagen structure affects tissue stiffness during progression of lung fibrosis and identifies a potential

New research in The FASEB Journal explored why a group of young, healthy adults residing at high altitude lost muscle mass while severely underfed and consuming the same high-protein diet that preserved muscle during weight loss at sea level. A team led by Stefan M. Pasiakos, PhD, a nutritional physiologist at the U.S. Army Research

Pulmonary vein stenosis (PVS) is a rare disease in which abnormal cells build up inside the veins responsible for carrying oxygen-rich blood from the lungs to the heart. It restricts blood flow through these vessels, eventually sealing them off entirely if left untreated. Typically affecting young children, the most severe form of PVS progresses very

A new study showing significantly improved survival rates for patients with stage IV Wilms tumors with lung metastases was recently published in the Journal of Clinical Oncology. The outcomes of the study, “Treatment of Stage IV Favorable Histology Wilms Tumor With Lung Metastases: A Report From the Children’s Oncology Group AREN0533 Study,” will be a

A male’s total testosterone level may be linked to more than just sexual health and muscle mass preservation, a new study finds. Low amounts of the hormone could also be associated with chronic disease, even among men 40 years of age and younger. “If we look at data for men from a population level, it
