Abstract
Surveillance of emerging viral variants is critical to ensuring that blood screening and diagnostic tests detect all infections regardless of strain or geographic location. In this study, we conducted serological and molecular surveillance to monitor the prevalence and diversity of HIV, HBV, and HTLV in South Cameroon. The prevalence of HIV was 8.53%, HBV was 10.45%, and HTLV was 1.04% amongst study participants. Molecular characterization of 555 HIV-1 specimens identified incredible diversity, including 7 subtypes, 12 CRFs, 6 unclassified, 24 Group O and 2 Group N infections. Amongst 401 HBV sequences were found a rare HBV AE recombinant and two emerging sub-genotype A strains. In addition to HTLV-1 and HTLV-2 strains, sequencing confirmed the fifth known HTLV-3 infection to date. Continued HIV/HBV/HTLV surveillance and vigilance for newly emerging strains in South Cameroon will be essential to ensure diagnostic tests and research stay a step ahead of these rapidly evolving viruses.

Abstract
Abstract
In patients with peripheral arterial disease, maximum walking distance on a treadmill is commonly used for studying the effect of exercise on ankle systolic pressure. Exercise on the Monark bicycle ergometer for 1 min at a workload of 1 kp and cycling at 20 kph has been compared with treadmill walking in 30 patients presenting with calf pain on exercise at the vascular clinic and in 6 normal volunteers. The bicycle test produced a significant fall in ankle systolic pressure in all patients with advanced arterial disease. There was no statistical difference in the results obtained on the bicycle compared with the treadmill. There was better patient compliance with the bicycle test. The Monark bicycle ergometer, a simple inexpensive instrument, is a viable alternative to the treadmill for exercising arterial patients.
