Lung cancer (LC) and chronic obstructive pulmonary disease (COPD) represent leading causes of morbidity and mortality worldwide. Common risk factors lead to an increased inflammatory response, enhances oxidative stress, and changes in lung microenvironment contributing to fine-tuned interaction between these respiratory disorders. ⋯ Better understanding LC and COPD coexistence may impact on clinical scenario influencing therapeutic approach. In this review, we describe the basis of this network and how the complex interplay between these respiratory disorders affects the clinical decision-making process.

The characteristic features of chronic obstructive pulmonary disease (COPD) include inflammation and remodeling of the lower airways and lung parenchyma together with activation of inflammatory and immune processes. Due to the increasing habit of cigarette smoking worldwide COPD prevalence is increasing globally. Current therapies are unable to prevent COPD progression in many patients or target many of its hallmark characteristics which may reflect the lack of adequate biomarkers to detect the heterogeneous clinical and molecular nature of COPD. ⋯ We also highlight the evidence for new drugs or approaches to treat COPD identified using molecular and other approaches including kinase inhibitors, cytokine- and chemokine-directed biologicals and small molecules, anti-oxidants and redox signaling pathway inhibitors, inhaled anti-infectious agents and senolytics. It is important to consider the phenotypes/molecular endotypes of COPD patients together with specific outcome measures to target new therapies to particular COPD subtypes. This will require greater understanding of COPD molecular pathologies and a focus on biomarkers of predicting disease subsets and responder/non-responder populations.

The aim of this study was to evaluate the prognostic value of perinuclear antineutrophil cytoplasmic antibodies (p-ANCA) in subjects with primary sclerosing cholangitis (PSC) and in particular whether it is associated with inflammatory bowel disease (IBD). ⋯ IBD, or especially UC, is present in85% of patients with CSP and p-ANCA positivity, whereas 95% of patients with PSC who test negative for p-ANCA do not have IBD.

In the chronic obstructive pulmonary disease (COPD), lung and chest-wall morphological alterations determine important and peculiar approaches to mechanical ventilation. Lung emphysema and reduced elastic recoil increase expiratory time, thus worsening dynamic hyperinflation, while airways chronic inflammation rises resistances and can determine distal air-trapping. Muscle wasting and fast fibers prevalence can result in weakness and in an earlier onset of muscle fatigue, prolonging the weaning process. In this narrative review, we explored the connection between altered pathophysiology and necessity for respiratory assistance in COPD, focusing on non-invasive and invasive respiratory management, lung monitoring and weaning difficulties.

Acute liver injury (ALI) is associated with the occurrence and progress of intrahepatic inflammation. Recent studies have shown that ADAM10, a significant member of metalloproteinase family, has modulated the inflammation level in various neurologic diseases. However, it is elusive whether ADAM10 regulation exert a hepatic protective effect on ALI by the suppression of inflammation level. The study aimed to explore the regulated function of ADAM10 on acute liver injury. ⋯ The above suggested that the inhibition of ADAM10 ameliorates ALI through inhibiting inflammation. Our research provides novel view on the ADAM10 modulation of process of ALI by the inflammation aspect and verify a potential target for the therapy of ALI in the future.
