Perspectives of the World Health Organization's physical activity guidelines among patients with musculoskeletal conditions: A mixed-methods survey.

Introduction: Physical activity (PA) promotion is a core element of musculoskeletal rehabilitation. Many people with musculoskeletal conditions do not meet PA guidelines, such as those provided by the World Health Organization (WHO). This study aimed to explore the level of awareness and perspectives on the WHO PA guidelines among people with musculoskeletal conditions and identify how patients can be supported with PA in clinical practice.

Total Disc Replacement Surgery in a Professional Australian Rugby League Player: A Case Report.

Chronic persistent lower back pain due to degenerative disc disease (DDD) of the lumbar spine is a common condition in the athletic population, which does not always improve with nonoperative treatment. We present a case report of a professional Australian rugby league player with DDD of the lumbar spine presenting with persistent lower back pain, which was not responding to conventional nonsurgical treatment. He then underwent a surgical total disc replacement of the lumbar spine and was subsequently able to return to playing professional rugby league at his previous level of competition.

[IFE: a new African orbivirus isolated from Eidolon helvum bats captured in Nigeria, Cameroon and the Central African Republic].

Eight viral isolates were recovered from Eidolon helvum bats collected in Nigeria and Cameroon in 1971 and from the Central African Republic in 1974. Subsequent studies showed that the agents from the three countries were similar and were strains of a new virus of the Orbivirus genus, family Reoviridae. This new virus was characterized with respect to its sensitivity to lipid solvents and to pH, its relative size and morphology by electron microscopy, its effect on mice experimentally infected by various routes, the histopathology found in infected mice, and its antigenic relationship or lack of a relationship to other known orbiviruses.

[Hematophagous diptera arbovirus vectors in Africa (author's transl)].

The authors, in a first part, show the general arthropods-viruses-vertebrates relationships and specially the different conditions of virus maintenance in the selvatic foci. Then they succinctly give the main characteristics of the vectors bioecology useful for understanding the epidemiology of arbovirus diseases of man and domestic animals. Thus diptera vectors of o'nyong-nyong and chikungunya fevers, yellow fever, dengue fever, Wesselsbron, Sindbis, and West Nile viruses, Rift Valley fever, sandfly fevers, bluetongue and african horsesickness are recorded.

[Isolation of a strain of Mokola virus in Cameroon (author's transl)].

A strain of Mokola virus has been isolated in Cameroon from a shrew (Crocidura sp.). In Nigeria, where the virus was isolated for the first time, two human cases with one death were reported.
