＜正＞ Lightning discharges range from low current cloud （CLD） events that can have sub-kilometer lengths to large cloud-to-ground （CG） return strokes with peak currents of several hundred kA and channel lengths greater than 10 km. This range of events cannot be detected and located using a single technique. In this paper, various detection technologies and location methods are summarized. These technologies are distinguished by their frequency ranges of operation (VLF,

AIM To describe factors associated with treatment failure and frequency of resistance-associated substitutions(RAS).METHODS Human immunodeficiency virus(HIV)/hepatitis C virus(HCV) coinfected patients starting a first direct-acting antiviral(DAA) regimen before February 2016 and included in the French ANRS CO13 HEPAVIH cohort were eligible. Failure was defined as:(1) non-response [HCV-RNA remained detectable during treatment, at end of treatment(EOT)]; and(2) relapse(HCVRNA suppressed at EOT but detectable thereafter). Sequencing analysis was performed to describe prevalence of drug class-specific RAS. Factors associated with failure were determined using logistic regression *** Among 559 patients, 77% had suppressed plasma HIV-RNA < 50 copies/mL at DAA treatment initiation, 41% were cirrhotic, and 68% were HCV treatmentexperienced. Virological treatment failures occurred in 22 patients and were mainly relapses(17, 77%) then undefined failures(3, 14%) and non-responses(2, 9%). Mean treatment duration was 16 wk overall. Posttreatment NS3, NS5 A or NS5 B RAS were detected in 10/14 patients with samples available for sequencing analysis. After adjustment for age, sex, ribavirin use, HCV genotype and treatment duration, low platelet count was the only factor significantly associated with a higher risk of failure(OR: 6.5; 95%CI: 1.8-22.6). CONCLUSION Only 3.9% HIV-HCV coinfected patients failed DAA regimens and RAS were found in 70% of those failing. Low platelet count was independently associated with virological failure.
