Article Synopsis
  • This study focuses on the use of noninvasive diagnostic methods to detect esophageal varices (EVs) in patients with compensated cirrhosis, contrasting with the traditional invasive method of upper endoscopy.
  • Conducted on 50 patients at a hospital in Cape Town, the study analyzed various clinical and lab data, showing that 68% of participants had EVs, primarily caused by alcohol, hepatitis B, or autoimmune factors.
  • Key findings emphasize significant differences in factors like liver and spleen stiffness, platelet counts, and dimensions that could enhance the accuracy of noninvasive tools for identifying EVs in patients.

Introduction: Many types of prostate cancer present minimal risk to a man's lifespan or well-being, but existing terminology makes it difficult for men to distinguish these from high-risk prostate cancers. This study aims to explore whether using an alternative label for low-risk prostate cancer influences management choice and anxiety levels among Australian men and their partners.

Methods And Analysis: We will run two separate studies for Australian men and Australian women with a male partner.

The development of tick resistance to chemical control plays a major role in the increasing global economic impact of ticks on cattle farming. Reports on acaricide resistance of Rhipicephalus decoloratus, endemic to Africa and South Africa, are relatively few compared to the closely related and globally distributed Rhipicephalus microplus. In South Africa, ectoparasite control became the sole responsibility of each commercial producer when compulsory dipping was phased out from 1984.

In South Africa, acaricides are widely used for tick control but very few reports are available on resistance development of Rhipicephalus (Boophilus) decoloratus Koch to chemical control on commercial farming systems in Africa, south of the Sahara. Resistance to different acaricide classes reported over the years was mostly from localised communal farming systems. This report addresses the lack of available information on resistance development by reviewing results found during a National Tick Resistance Survey carried out from 1998 to 2001, laying the foundation for more recent research on resistance development, and the evolution of resistance over the years.

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention option, but cost-effectiveness is sensitive to implementation and program costs. Studies indicate that, in addition to direct delivery cost, PrEP provision requires substantial demand creation and client support to encourage PrEP initiation and persistence. We estimated the cost of providing PrEP in Zambia through different PrEP delivery models.
