Use of inhaled devices during a hospital exacerbation of COPD: a summary of an interdisciplinary audit held at ICS Maugeri Pavia, Italy (March-June 2019).

To date treatment protocols in Respiratory and or Internal departments across Italy for treatment of chronic obstructive pulmonary disease (COPD) patients at hospital admission with relapse due to exacerbation do not find adequate support in current guidelines. Here we describe the results of a recent clinical audit, including a systematic review of practices reported in literature and an open discussion comparing these to current real-life procedures. The process was dived into two 8-hour-audits 3 months apart in order to allow work on the field in between meeting and involved 13 participants (3 nurses, 1 physiotherapist, 2 internists and 7 pulmonologists). This document reports the opinions of the experts and their consensus, leading to a bundle of multidisciplinary statements on the use of inhaled drugs for hospitalized COPD patients. Recommendations and topics addressed include: i) monitoring and diagnosis during the first 24 h after admission; ii) treatment algorithm and options (i.e., short and long acting bronchodilators); iii) bronchodilator dosages when switching device or using spacer; iv) flow measurement systems for shifting to LABA+LAMA within 48 h; v) when nebulizers are recommended; vi) use of SMI to deliver LABA+LAMA when patient needs SABA 30 litres/min; viii) contraindication to use DPI; ix) continuation of LABA-LAMA when patient is already on therapy; x) possible LABA-LAMA dosage increase; xi) use of SABA and/or SAMA in addition to LABA+LABA; xii) use of SABA+SAMA restricted to real need; xiii) reconciliation of drugs in presence of comorbidities; xiv) check of knowledge and skills on inhalation therapy; xv) discharge bundle; xvi) use of MDI and SMI in tracheostomized patients in spontaneous and ventilated breathing

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
