TL;DR: The first World Report on Violence and Health analyses different types of violence including child abuse and neglect, youth violence, intimate partner violence, sexual violence, elder abuse, self-directed violence, and collective violence.
Abstract: In 1996, the World Health Assembly declared violence a major public health issue. To follow up on this resolution, on October 3 this year, WHO released the first World Report on Violence and Health. The report analyses different types of violence including child abuse and neglect, youth violence, intimate partner violence, sexual violence, elder abuse, self-directed violence, and collective violence. For all these types of violence, the report explores the magnitude of the health and social effects, the risk and protective factors, and the types of prevention efforts that have been initiated. The launch of the report will be followed by a 1-year Global Campaign on Violence Prevention, focusing on implementation of the recommendations. This article summarises some of the main points of the world report.

TL;DR: A class of linear rank statistics is proposed for the k-sample problem with rightcensored survival data andMartingale theory is used to establish asymptotic normality of test statistics under the null hypotheses considered, and to derive expressions for asymPTotic relative efficiencies under contiguous sequences of alternative hypotheses.

TL;DR: A triatomine fauna classification is presented that corresponds to the eco-epidemiological conditions of the country, considering altitude as the factor determining the geographical distribution of these vectors.
Abstract: Information concerning triatomine records from provinces and municipalities was accumulated-including data indicating natural infections with trypanosomatides-that has been previously published or reported by Colombian provincial health services and research institutes. Altitude appeared to be the main factor responsible for the distribution of the insects. Illustrations summarize the information provided by the above records. A triatomine fauna classification is presented that corresponds to the eco-epidemiological conditions of the country, considering altitude as the factor determining the geographical distribution of these vectors. Rhodnius prolixus, Triatoma dimidiata, Triatoma maculata and Triatoma venosa are considered the major transmission risk species in Colombia, according to the frequency in which they are reported inside dwellings and peridomiciliary areas. Entomological surveillance providess a necessary tool to reinforce the control strategies for Chagas disease. This also allows the evaluation of transmission risk that the sylvatic triatomines represent in Colombia.

TL;DR: Rickettsial infection in capybaras in different areas of the state of São Paulo is evaluated, and the first evidence of R. bellii natural infection in vertebrate hosts is reported.
Abstract: Introduction. In Brazil, capybaras (Hydrochoerus hydrochaeris) are important hosts for Amblyomma ticks, which in turn can transmit rickettsiae to humans and animals. Therefore, capybaras are potential sentinels for rickettsial infection. Objective. The present study evaluated rickettsial infection in capybaras in different areas of the state of Sao Paulo, where rickettsiosis has never been reported. Materials and methods. Blood sera from 73 capybaras from six localities in Sao Paulo were tested by indirect immunofluorescence assay using Rickettsia rickettsii, Rickettsia parkeri, and Rickettsia bellii antigens. Capybara spleens were tested by PCR, targeting a fragment of the rickettsial gltA gene. Ticks were collected from each capybara sample and taxonomically identified to species. Results. A total of 94 positively reacting capybara samples, 19 (26.0%), 25 (34.2%), and 50 (68.5%) capybara sera reacted to R. rickettsii, R. parkeri, and R. bellii, respectively. Twenty-five capybara sera showed titers to R. bellii at least four-fold higher than to any of the other two antigens. These sera were considered homologous to R. bellii. Using the same criteria, 3 capybara sera were considered homologous to R. parkeri. No sera were be considered homologous to R. rickettsii. No rickettsial DNA was detected in capybara spleen samples. Ticks collected on capybaras were Amblyomma dubitatum and Amblyomma cajennense. Conclusions. The first evidence is reported of R. bellii natural infection in vertebrate hosts, and the first evidence of R. parkeri infection in capybaras. While R. parkeri is known to infect and cause disease in humans, no similar evidence for human infection has been indicated by R. bellii.
