Sepsis and septic shock in the tropics are caused by a wide array of organisms. These infections are encountered mainly in low and middle-income countries (LMIC) where a lack of infrastructure and medical facilities contribute to the high morbidity and mortality. Published sepsis guidelines are based on studies primarily performed in high income countries and as such recommendations may or may not be relevant to practice in the tropics. Failure to adhere to guidelines, particularly among non-intensive care specialists even in high-income countries, is an area of concern for sepsis management...

INTRODUCTION: Relatively little is known about the long-term health of former elite rugby players, or former sportspeople more generally. As well as the potential benefits of being former elite sportspersons, there may be potential health risks from exposures occurring during an individual's playing career, as well as following retirement. Each contact sport has vastly different playing dynamics, therefore exposing its players to different types of potential traumas. Current evidence suggests that these are not necessarily comparable in terms of pathophysiology, and their potential long-term adverse effects might also differ...
