Impact of the COVID-19 pandemic on tuberculosis services

Background: In Portugal, Outpatient Tuberculosis Centres (OTBC) are responsible for the diagnosis, treatment, screening and prevention of tuberculosis (TB), and only severe or resistant cases are hospitalized. Aim: To understand how infection control norms and standards were applied and how these centres responded during the pandemic. Method: We sent an electronic questionnaire to all coordinators of OTBC. The questionnaire included questions on infection control during the COVID-19 pandemic and evaluation of the functioning of the OTBC in two periods: during the 1st National State of Emergency and after 1 year. Results: Thirty-two responses were obtained (52.5%). The infection control norms were globally applied; diagnosis, treatment, and prevention were kept, and contact screening was only affected during the 1st State of Emergency. However, half of the respondents (53.1%) believed that there were diagnostic delays during the 1st State of Emergency, rising to 68.8% after 1 year. Only 31.3% performed Directly Observed Therapy (DOT) in all patients during the 1st State of Emergency, and 59.4% after 1 year. Half the inquiries expected an increase in TB incidence in the near future. Conclusion: The pandemic affected OTBC functioning, although the services were kept open; diagnostic delay and DOT appliance were the most affected. © 2022 Sociedade Portuguesa de PneumologiaFunding text 1: No specific funding was received for this work.

Dynamical Boson Stars

The idea of stable, localized bundles of energy has strong appeal as a model for particles. In the 1950s John Wheeler envisioned such bundles as smooth configurations of electromagnetic energy that he called {\em geons}, but none were found. Instead, particle-like solutions were found in the late 1960s with the addition of a scalar field, and these were given the name {\em boson stars}. Since then, boson stars find use in a wide variety of models as sources of dark matter, as black hole mimickers, in simple models of binary systems, and as a tool in finding black holes in higher dimensions with only a single killing vector. We discuss important varieties of boson stars, their dynamic properties, and some of their uses, concentrating on recent efforts.Comment: 79 pages, 25 figures, invited review for Living Reviews in Relativity; major revision in 201

Performance of CMS muon reconstruction in pp collision events at sqrt(s) = 7 TeV

The performance of muon reconstruction, identification, and triggering in CMS has been studied using 40 inverse picobarns of data collected in pp collisions at sqrt(s) = 7 TeV at the LHC in 2010. A few benchmark sets of selection criteria covering a wide range of physics analysis needs have been examined. For all considered selections, the efficiency to reconstruct and identify a muon with a transverse momentum pT larger than a few GeV is above 95% over the whole region of pseudorapidity covered by the CMS muon system, abs(eta) < 2.4, while the probability to misidentify a hadron as a muon is well below 1%. The efficiency to trigger on single muons with pT above a few GeV is higher than 90% over the full eta range, and typically substantially better. The overall momentum scale is measured to a precision of 0.2% with muons from Z decays. The transverse momentum resolution varies from 1% to 6% depending on pseudorapidity for muons with pT below 100 GeV and, using cosmic rays, it is shown to be better than 10% in the central region up to pT = 1 TeV. Observed distributions of all quantities are well reproduced by the Monte Carlo simulation.Comment: Replaced with published version. Added journal reference and DO
