DNA repair as an emerging target for COPD-lung cancer overlap
Publication date: Available online 7 January 2019Source: Respiratory InvestigationAuthor(s): Catherine R. SearsAbstractCigarette smoking is the leading cause of lung cancer and chronic obstructive pulmonary disease (COPD). Many of the detrimental effects of cigarette smoke have been attributed to the development of DNA damage, either directly from chemicals contained in cigarette smoke or as a product of cigarette smoke-induced inflammation and oxidative stress. In this review, we discuss the environmental, epidemiological, and physiological links between COPD and lung cancer and the likely role of DNA damage and repair in...

Development of lung cancer in patients with nontuberculous mycobacterial lung disease
ConclusionsWe identified the clinical characteristics of eight MAC-LD patients who developed lung cancer. NTM-LD may be a risk factor for lung cancer development. Periodic follow-up with chest CT might contribute to early diagnosis and curative therapy for lung cancer. (Source: Respiratory Investigation)

Combination of assist use of short-acting beta-2 agonists inhalation and guidance based on patient-specific restrictions in daily behavior: Impact on physical activity of Japanese patients with chronic obstructive pulmonary disease
ConclusionsAssist use of SABA targeting patient-specific restrictions, particularly when better lung function is still preserved, could be a useful approach for improving physical activity in patients with COPD. (Source: Respiratory Investigation)

Leukotrienes: One step in our understanding of asthma
Publication date: Available online 30 December 2018Source: Respiratory InvestigationAuthor(s): Pierre SiroisAbstractThe steps leading to the discovery of leukotrienes and the researchers that played a major part in this long process are presented. The pharmacology of these exquisitely potent compounds shows that they express bronchoconstrictor activity and numerous cellular effects via very specific receptors. Experimental evidence strongly suggests that these mediators play a significant role in asthma physiopathology. Numerous approaches were taken to block their effects on the lungs and this led to the discovery of sele...

Lung transplant candidates with idiopathic pulmonary fibrosis and long-term pirfenidone therapy: Treatment feasibility influences waitlist survival
ConclusionsPatients with IPF successfully managed with long-term Pirfenidone therapy achieved favorable outcomes after LTx registration, comparable to other patients with LTx indications. The tolerability to antifibrotic therapy can be a predictor of waitlist survival. (Source: Respiratory Investigation)

Cryobiopsy with endobronchial ultrasonography using a guide sheath for peripheral pulmonary lesions and DNA analysis by next generation sequencing and rapid on-site evaluation
ConclusionsCryo with EBUS-GS for PPLs is a safe and potentially useful diagnostic strategy. It has a high diagnostic yield, and provides significantly larger specimens than TBB. It also provides high quantity and quality of DNA for NGS and high concordance rate between ROSE and the final diagnosis. (Source: Respiratory Investigation)

Use of vasodilators for the treatment of pulmonary veno-occlusive disease and pulmonary capillary hemangiomatosis: A systematic review
ConclusionsThe present study demonstrates the potential efficacy and difficulties in the use of vasodilators in patients with PVOD/PCH; however, drawing a firm conclusion was difficult because of the lack of randomized controlled trials. Further research is needed to ascertain if vasodilator use is beneficial and safe in patients with PVOD/PCH. (Source: Respiratory Investigation)

Role of microRNA in severe asthma
Publication date: Available online 16 November 2018Source: Respiratory InvestigationAuthor(s): Kittipong ManeechotesuwanAbstractThe various roles of microRNAs (miRNAs) in the epigenetic regulation of human disease are gaining importance as areas of research, and a better understanding of these roles may identify targets for development of novel therapies for severe asthma. MiRNAs, a class of small non-coding RNAs that serve as post-transcriptional gene repressors, are recognized as critical components in regulating tissue homeostasis. Alteration in miRNA expression disrupts homeostasis and is an underlying mechanism for de...

The clinical features of older patients with lung cancer in comparison with their younger counterparts
ConclusionsWe should positively consider standard treatments for older patients. However, not only their shorter life expectancy but also their poor PS and multiple comorbidities that sometimes render patients unable to receive standard treatments and several chemotherapy regimens, make their prognosis poor. The standard treatments for older patients, especially in locally advanced stages, require modification. (Source: Respiratory Investigation)

Safety and pharmacokinetics of Alpha-1 MP (Prolastin®-C) in Japanese patients with alpha1-antitrypsin (AAT) deficiency
ConclusionsThe PK and safety of Alpha-1 MP in Japanese subjects with AATD were consistent with the Alpha-1 MP profile in non-Japanese subjects (ClinicalTrials.gov: NCT02870309; JAPIC CTI: JapicCTI-163160). (Source: Respiratory Investigation)
