TL;DR: Prolonged courses of artemisinin-based combination therapies are currently efficacious in areas where standard 3-day treatments are failing, and the incidence of pretreatment and post-treatment gametocytemia was higher among patients with slow parasite clearance, suggesting greater potential for transmission.

TL;DR: Assessment of the spread of artemisinin-resistant P falciparum in Myanmar finds Artemisinin resistance extends across much of Myanmar, and Appropriate therapeutic regimens should be tested urgently and implemented comprehensively if spread of warfarin resistance to other regions is to be avoided.

TL;DR: This proposed multicentre randomised clinical trial aims to provide evidence across a variety of endemic settings on the safety and efficacy of high dose short course primaquine in glucose-6-phosphate-dehydrogenase (G6PD) normal patients, contributing to decreased transmission and a reduce parasite reservoir.
Journal ArticleDOI
Epidemiology of prostatitis

TL;DR: The prevalence of prostatitis symptoms is high, comparable to rates of ischaemic heart disease and diabetes, and clinical evaluation appears necessary to verify that prost atitis is responsible for patients' symptoms.

TL;DR: Dihydroartemisinin-piperaquine is not treating malaria effectively across the eastern Greater Mekong subregion, and a highly drug-resistant P falciparum co-lineage is evolving, acquiring new resistance mechanisms, and spreading.
