Venous Thromboembolism in Patients Diagnosed With Lung Cancer.

Purpose: Considering the high prevalence of lung cancer, our purpose was to summarize the existing literature to identify the several factors that contribute to the increased risk of venous thromboembolism (VTE) in patients with lung cancer and to analyze the current recommendations for thromboprophylaxis and treatment of VTE in those patients.

Methods: We searched the Medline and EMBASE databases from February 1985 to February 2014 to identify retrospective and prospective randomized controlled studies that investigate one or more risk factors for VTEs in patients with lung cancer.

Results: A VTE is a major complication for patients diagnosed with lung cancer.

Genetic alterations of glutathione S-transferases in asthma: do they modulate lung growth and response to environmental stimuli?

Glutathione S-transferases (GSTs) constitute a super family of dimeric phase II metabolic enzymes that catalyze the conjugation of reduced glutathione with various electrophilic compounds and reactive oxygen species (ROS). Failure to detoxify ROS, as a sequel of altered GST genotype is able to aggravate the inflammatory cascade, promote bronchoconstrictor mechanisms, activate asthma-like symptomatology, and hamper lung development. Intriguingly, the same GST genotype can aggravate or improve physiological traits and maturation of respiratory system, from gestation to late adulthood.
