The Microbes Causing Cystic Fibrosis

A new study, recently published in Nature Communications, at infections in Danish youth with CF over a period of 10 years. This is the largest longitudinal study to date of the evolution; both involving traits and genes of the disease-causing microbes that persistently infect young CF-patients. CF-patients have a genetic defect which results in dehydrated sticky…

Therapeutic Strategies For Fibrotic Disorders

Fibrosis is the formation of excess fibrous connective tissue in an organ or tissue in a reparative or reactive process. This can be a reactive, benign, or pathological state. In response to injury, this is scarring, and if fibrosis arises from a single cell line, this is a fibroma. Physiologically, fibrosis acts to deposit connective…

Black lung disease

Fearing retaliation, May Skip Black Lung Screenings

Federal officials are examining potential barriers; such as a fear of retaliation from employers; that may explain why only about one-third of coal miners participate in a program to screen for black lung disease even as the number of workers suffering from the deadly condition is rising. The lack of participation concerns lawmakers and the…

Health Risks Associated With Smoking

Smoking is a practice in which a substance is resulting in smoke breathed in to tested and absorbed into the bloodstream. Most commonly the substance is the dried leaves; of the tobacco plant which have been rolled into a small square of rice paper to create a small, round cylinder called a “cigarette”. Smoking is…

Lungs Are Necessary But Did You know They Also Are Beautiful?

Lungs are remarkable organs that continuously achieve amazing feats; which they do so well that we take them for granted; except when their function is diminished. It all happens in a space inside your chest; divided in two and reduced by the presence of the heart; the great vessels and the esophagus. With Supreme Court…

Smokers

Why Non-Smokers As Well As Smokers Develop Chronic Lung Disease

The new study, published in Nature Genetics; shows that genetic differences help explain why some people who have never smoked develop the chronic obstructive pulmonary disease (COPD); why some smokers are at higher risk of getting the disease than other smokers. During the two-year study; researchers measured 20 million differences in the DNA in each of…

E-Cigarette Flavors Could Harm Respiratory Tract

Two chemicals commonly used as e-cigarette flavors might harm users’ airway passages, a small experiment suggests. Researchers exposed human bronchial epithelial cells to two flavoring compounds: diacetyl a chemical with a butter-like smell – and its “chemical cousin” 2,3-pentanedione. Both chemicals induced hundreds of genetic changes in the cells. The chemicals also impaired the ability…

Lung cancer

Origin Of Resistance To Lung-Cancer Drug Discovered

Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. This growth can spread beyond the lung by the process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung, known as primary lung cancers, are carcinomas. The two main types are small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma…

Human lung cells

Heated Tobacco Device Causes Same Damage To Lung Cells

A new study that directly compares new heated tobacco devices with vaping and traditional cigarettes shows that all three are toxic to human lung cells. The study published in ERJ Open Research suggests that the new device; which heats solid tobacco instead of an e-liquid; is no less toxic to the cells than ordinary cigarette smoke. Researchers…

Asthma

Guideline Outlines Step-down Therapy for Asthma

A new guideline from the American College of Allergy, Asthma, and Immunology provides evidence-based recommendations for stepping down asthma medications for patients who have achieved sustained asthma control. Stepping down asthma controller therapy allows clinicians to identify the minimum effective treatment needed to maintain wellness while reducing the burden of treatment with respect to adverse events,…

Graphene Could Hold Key Of Early Lung Cancer Diagnosis

The wonder-material graphene could hold the key to unlocking the next generation of the advanced; early-stage lung cancer diagnosis. A team of scientists from the University of Exeter has developed a new technique that could create a highly sensitive graphene biosensor with the capability to detect molecules of the most common lung cancer biomarkers. The…

Free Lung Cancer Screening Program

A free, simple screening for lung cancer can save patient money while building a healthy relationship for any medical needs they may have in the future. The research, published in the Annals of Thoracic Surgery, shows the partnership can beneficial for patients looking for cardiology specialists; family medical care and other health-related issues, as well as…
