Background: The services of most clinical laboratories in Africa regarding the diagnosis of Trichomonas vaginalis are largely dependent on the urine direct wet-mount method. However, the exclusive use of urine-based detection may not be appropriate. The culture method is considered the “gold standard” for the diagnosis of T. vaginalis. However, thi...

Background: Prehypertension has been shown to increase future risk of hypertension. Some demographic and lifestyle characteristics have been implicated to increase the risk of development of prehypertension. Yet, there is paucity of data on the current prevalence of prehypertension and its associated risk factors in Ghana. This study evaluated the...
