Medication non-adherence to asthma and chronic obstructive pulmonary disease therapy poses a significant burden for patients and societies. Non-adherence encompasses poor initiation, implementation (including poor inhalation technique) and non-persistence. Globally, non-adherence is associated with poor clinical outcomes, reduced quality of life and high healthcare and societal costs. ⋯ For example, their cost-effectiveness and budget impact need to be examined. It is likely that smart inhalers are particularly cost-effective in specific asthma and chronic obstructive pulmonary disease subgroups, including patients with asthma eligible for additional GINA-5 therapy (oral corticosteroids or biologics), patients with severe asthma in GINA-5, patients with asthma with short-acting beta2 agonists overuse, patients with asthma and chronic obstructive pulmonary disease with frequent exacerbations and patients with asthma and chronic obstructive pulmonary disease of working-age. While there is high potential and evidence is accumulating, a final push seems needed to cost-effectively integrate smart inhalers in the daily management of patients with asthma and chronic obstructive pulmonary disease.

Putting artificial intelligence (AI) on the spot: machine learning evaluation of pulmonary nodules.
Lung cancer remains the leading cause of cancer related death world-wide despite advances in treatment. This largely relates to the fact that many of these patients already have advanced diseases at the time of initial diagnosis. ⋯ Deep learning (DL) and convolutional neural networks (CNNs) have shown promising results in pulmonary nodule detection and have also excelled in segmentation and classification of pulmonary nodules. This review aims to provide an overview of progress that has been made in AI recently for pulmonary nodule detection and characterization with the ultimate goal of lung cancer prediction and classification while outlining some of the pitfalls and challenges that remain to bring such advancements to routine clinical use.

Review
Uniportal video-assisted thoracoscopic lung sparing tracheo-bronchial and carinal sleeve resections.
Pathology arising from the intrathoracic portion of the trachea (distal trachea), the carina and the main bronchi is usually neoplastic and is mainly treated with surgery. Resection of the intrathoracic portion of the trachea, the carina and the main bronchi for neoplastic lesions does not necessitate lung resection and is traditionally being conducted via open surgery. Video-assisted thoracic surgery (VATS) is witnessing an exponential growth and is the treatment of choice for early-stage non-small cell lung cancer (NSCLC). ⋯ Ventilation is achieved through an endobronchial catheter, inserted into the left main bronchus through which a high-frequency jet ventilation catheter can be also inserted through it. The rationale of applying a minimally invasive technique for the conduction of tracheal and carinal resections, is to exploit its advantages, namely less pain, earlier mobilization and lower morbidity. Uniportal video-assisted resections of the distal trachea, carina and the main bronchi, are safe when conducted by experienced surgical and anesthetic teams.

In December 2019, the coronavirus disease 2019 (COVID-19) caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was discovered. Since its emergence, COVID-19 has been outbreaking rapidly worldwide, where the virus has so far caused the death of hundreds of thousands and infected more than a million, what has been called a pandemic by the World Health Organization (WHO). According to the WHO-Coronavirus disease 2019 Situation Report-142, by June 10, 2020, there are 7,145,539 confirmed cases and 408,025 deaths. ⋯ Some Western medicines including remdesivir, chloroquine, hydroxychloroquine, favipiravir, lopinavir/ritonavir, and arbidol, as well as some traditional Chinese medicine (TCM) such as Qingfei Paidu decoction, Yupingfeng, Lianhua Qingwen, and TCM injections have revealed a relative activity against SARS-CoV-2 in vitro, in observational studies, and in clinical trials. However, further extensive studies and clinical trials including double-blind and randomized clinical trials, with a higher number of patients, are necessary to confirm the activity of these medicines. There are several ongoing trials conducted on the drugs of COVID-19, and the results are urgently needed to make a suitable treatment recommendation.

Despite multiple recent advances, the diagnosis and management of lung cancer remain challenging and it continues to be the deadliest malignancy. In 2011, the National Lung Screening Trial (NLST) reported 20% reduction in lung cancer related mortality using annual low dose chest computed tomography (CT). These results led to the approval and nationwide establishment of lung cancer CT-based lung cancer screening programs. ⋯ Radiomics is a recently coined term which refers to the process of imaging feature extraction and quantitative analysis of clinical diagnostic images to characterize the nodule phenotype beyond what is possible with conventional radiologist assessment. Even though it is still in early phase, several studies have already demonstrated that radiomics approaches are potentially useful for lung nodule classification, risk stratification, individualized management and prediction of overall prognosis. The goal of this review is to summarize the current literature regarding the radiomics of screen-detected lung nodules, highlight potential challenges and discuss its clinical application along with future goals and challenges.
