RATIONALE: Gene promoter hypermethylation detected in sputum assesses the extent of field cancerization and predicts lung cancer (LC) risk in ever smokers. A rapid decline of forced expiratory volume in 1 second (FEV1) is a major driver for development of airway obstruction. OBJECTIVES: To assess the effects of methylation of 12 genes on FEV1 decline and of FEV1 decline on subsequent LC incidence using two independent, longitudinal cohorts (i.e., Lovelace Smokers cohort [LSC] and Pittsburgh Lung Screening Study [PLuSS])...

BACKGROUND: Several studies have previously analyzed the relationship between QOL and signs of dysphagia in patients treated for head and neck cancer and have reported heterogeneous findings. To the best of our knowledge, no study has previously investigated this relationship among patients who underwent open partial horizontal laryngectomy (OPHL). The aim of the study is to determine if patient-reported swallowing-related QOL can discriminate between safe and unsafe swallowing in OPHL patients...

In this work we aim to show how Genome Scale Metabolic Models (GSMMs) can be used as tools for drug design. By comparing the chemical structures of human metabolites (obtained using their KEGG indexes) and the compounds contained in the DrugBank database, we have observed that compounds showing Tanimoto scores higher than 0.9 with a metabolite, are 29.5 times more likely to bind the enzymes metabolizing the considered metabolite, than ligands chosen randomly. By using RNA-seq data to constrain a human GSMM it is possible to obtain an estimation of its distribution of metabolic fluxes and to quantify the effects of restraining the rate of chosen metabolic reactions (for example using a drug that inhibits the enzymes catalyzing the mentioned reactions)...

With the development of key techniques and programs, the concept of enhanced recovery after surgery (ERAS) has been utilized in a wide range of diseases and surgical specialties. The key technological elements of enhanced lung recovery after surgery (ELRAS), which is regarded as the mainstay of minimally invasive lung cancer surgery, consist of the airway management and the lung protection. A multidisciplinary team cooperation based on physicians, nurses and rehabilitative therapists is needed to achieve the goals of airway management and lung protection, thus establishing a comprehensive ELRAS system for lung cancer patients...

Hyperpolarized (129) Xenon-MRI (HP (129) Xe MRI) is an emerging imaging modality that allows assessment of both ventilation and gas transfer. Most research to date has focused on non-malignant pulmonary diseases. However, the capability of evaluating the two primary physiological processes of the lung (ventilation and gas transfer) makes HP (129) Xe MRI a promising imaging modality in the management of patients with lung cancer.

Air pollution exposure, including passenger car emissions, may cause substantial respiratory health effects and cancer death. In western countries, the majority of passenger cars are driven by gasoline fuel. Recently, new motor technologies and ethanol fuels have been introduced to the market, but potential health effects have not been thoroughly investigated. We developed and verified a coculture model composed of bronchial epithelial cells (ECs) and natural killer cells (NKs) mimicking the human airways to compare toxic effects between pure gasoline (E0) and ethanol-gasoline-blend (E85, 85% ethanol, 15% gasoline) exhaust emitted from a flexfuel gasoline car...

Roflumilast, a potent and selective inhibitor of phosphodiesterase-4 (PDE4), has been used in treatment of COPD. PDE4 inhibitor is associated with inhibition of chronic airway inflammation, oxidative stress, and mesenchymal markers in B(a)P-induced lung tumors. The aim of this study was to assess whether roflumilast alone or added to inhaled budesonide might have dose-dependent inhibition on lung carcinogenesis induced by carcinogen B(a)P in mice. Female A/J mice were given a single dose of benzo(a)pyrene. Administration of roflumilast (1mg/kg or 5mg/kg) via oral gavage and aerosolized budesonide (2...

Airway epithelial cells are prone to the damage caused by lung cancer risk factors, such as cigarette smoking. Little is known about surrogate biomarkers in the bronchial airway epithelium that can be used to assess the effect of potential chemoprevention drugs on lung adenocarcinoma formation/progression. Pioglitazone has been suggested as a chemoprevention drug for lung cancer. To study the mechanisms underlying the role of pioglitazone in lung cancer prevention, we performed transcriptome sequencing (RNA-Seq) and found that Kras signaling was repressed by pioglitazone treatment in the airway epithelial cells of mice with lung adenocarcinoma (FDR q = 9...

With increases in survivorship for patients with head and neck cancer, attention is turning to quality-of-life issues for survivors. Care for these patients is multifaceted. Dysphagia and issues of voice/speech, airway obstruction, neck and shoulder dysfunction, lymphedema, and pain control are important to address. Rehabilitation interventions are patient-specific and aim to prevent, restore, compensate, and palliate symptoms and sequelae of treatment for optimal functioning. Central to providing comprehensive interdisciplinary care are the head and neck surgeon, laryngologist, and speech-language pathologist...

Worldwide, over 4 million premature deaths each year are attributed to the burning of biomass fuels for cooking and heating. Epidemiological studies associate household air pollution with lung diseases, including chronic obstructive pulmonary disease, lung cancer, and respiratory infections. Animal dung, a biomass fuel used by economically vulnerable populations, generates more toxic compounds per mass burned than other biomass fuels. The type of animal dung used varies widely depending on local agro-geography...
