Prevalence, knowledge and factors associated with shisha smoking among university students in Cameroon.

Young adults consider (water-pipe) less harmful than other smoking methods, but it has been reported to expose its users to excess levels of tobacco. This study sought to determine the prevalence, knowledge and factors associated with shisha use among university students in Buea, Cameroon. Consenting participants were included in a cross-sectional study.

Etiology and clinical characteristics of pediatric acute fever among hospitalized children in an endemic malaria transmission area of Cameroon in Central Africa.

Acute fever in the majority of children in resource-limited countries is attributable to malaria and often treated without laboratory evidence. The aim of the study was to characterize acute pediatric infectious fevers (APIF) in the pediatric department of the Douala Laquintinie Hospital. A cross-sectional study was conducted among children aged 2 months to 15 years who were admitted with an acute fever (anal temperature ≥ 37.

Increased glucocorticoid response to a novel stress in rats that have been restrained.

Rats exposed to repeated restraint stress (3 h of restraint on each of 3 days) lose weight during stress and do not return to the weight of nonstressed controls once stress ends. Others have reported that chronic stress raises the daily nadir of corticosterone release and increases the adrenal response to subsequent stress; therefore, we examined glucocorticoid release in rats that had been exposed to repeated restraint. Repeated restraint had no effect on the diurnal pattern of corticosterone or insulin release, measured 12 days after restraint had ended, indicating that the reduced weight of the rats is not associated with an elevated corticosterone-insulin ratio.
