Rehabilitation of torture survivors in five countries: common themes and challenges

<p>Abstract</p> <p>Background</p> <p>Torture continues to be a global problem and there is a need for prevention and rehabilitation efforts. There is little available data on torture survivors from studies designed and conducted by health professionals in low income countries. This study is a collaboration between five centres from Gaza, Egypt, Mexico, Honduras and South Africa who provide health, social and legal services to torture survivors, advocate for the prevention of torture and are part of the network of the International Rehabilitation Council for Torture Victims (IRCT).</p> <p>Methods</p> <p>Socio-demographic, clinical and torture exposure data was collected on the torture survivors attending the five centres at presentation and then at three and six month follow-up periods. This sample of torture survivors is presented using a range of descriptive statistics. Change over time is demonstrated with repeated measures analysis of variance.</p> <p>Results</p> <p>Of the 306 torture survivors, 23% were asylum seekers or refugees, 24% were socially isolated, 11% in prison. A high level of traumatic events was experienced. 64% had suffered head injury whilst tortured and 24% had ongoing torture injury problems. There was high prevalence of symptoms of anxiety, depression, post traumatic stress as well as medically unexplained somatic symptoms. The analysis demonstrates a modest drop in symptoms over the six months of the study.</p> <p>Conclusions</p> <p>Data showed that the torture survivors seen in these five centres had high levels of exposure to torture events and high rates of clinical symptoms. In order to provide effective services to torture survivors, health professionals at torture rehabilitation centres in low income countries need to be supported to collect relevant data to document the needs of torture survivors and to evaluate the centres' interventions.</p

Performance of the CMS muon trigger system in proton-proton collisions at √s = 13 TeV

The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC achieved instantaneous luminosities as high as 2 × 10 cm s while delivering proton-proton collisions at √s = 13 TeV. The challenge for the trigger system of the CMS experiment is to reduce the registered event rate from about 40 MHz to about 1 kHz. Significant improvements important for the success of the CMS physics program have been made to the muon trigger system via improved muon reconstruction and identification algorithms since the end of Run 1 and throughout the Run 2 data-taking period. The new algorithms maintain the acceptance of the muon triggers at the same or even lower rate throughout the data-taking period despite the increasing number of additional proton-proton interactions in each LHC bunch crossing. In this paper, the algorithms used in 2015 and 2016 and their improvements throughout 2017 and 2018 are described. Measurements of the CMS muon trigger performance for this data-taking period are presented, including efficiencies, transverse momentum resolution, trigger rates, and the purity of the selected muon sample. This paper focuses on the single- and double-muon triggers with the lowest sustainable transverse momentum thresholds used by CMS. The efficiency is measured in a transverse momentum range from 8 to several hundred GeV
