Clinical characteristics, use and switch of drugs for obstructive airway diseases among patients with COPD experiencing an exacerbation: a retrospective analysis of Italian administrative healthcare data.

Background: Chronic obstructive pulmonary disease (COPD) represents an important health challenge, despite being preventable and manageable thanks to up-to-date recommendations. In Italy, the pharmaceutical care of COPD patients is still ill-timed and inaccurate. This study aimed to describe the treatment of COPD patients in Italy and possible switches following an exacerbation.

Brazilian version of the "Primary Sjögren's Syndrome - Quality of Life questionnaire (PSS-QoL)": translation, cross-cultural adaptation and validation.

Background: The Primary Sjögren's Syndrome Quality of Life questionnaire (PSS-QoL) is the first specific instrument to assess health-related quality of life (HRQoL) in Sjögren's disease (SjD). The aim is to translate and cross-culturally adapt the PSS-QoL into Brazilian Portuguese and to evaluate its psychometric properties.

Methods: The original English version was translated into Brazilian Portuguese by two native Brazilians who were proficient in the English language.

Enrichment of histone tail methylated lysine residues cavitand-decorated magnetic nanoparticles for ultra-sensitive proteomics.

Nearly every protein in the human body is modified with post-translational modifications (PTMs). PTMs affect proteins on many levels, including their function, interaction, half-life, and localization. Specifically, for histone proteins, PTMs such as lysine methylation and acetylation play essential roles in chromatin dynamic regulations.
