Pump thrombosis occurred at a similar rate [RA 3/10 (30.0%) vs. RV 6/20 (30.0%), P = 1], as did GI bleeding [RA 10/35 (28.6%) vs. RV 5/21 (23.8%), P = .94] during the follow-up time period. Kaplan-Meier analysis when censored for transplant showed higher survival with RA HVAD compared to RV HVAD (P = .036), with an estimated survival at 1 year of 91.7% (95% CI 77.3-100.0) in RA HVAD versus 66.2% (95% CI 48.9-89.6) for RV HVAD. RA HVAD appears to be a viable option for durable right-sided support with outcomes at least comparable to RV HVAD. © 2020 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.Although antibodies are considered critical for malaria protection, little is known about the mechanisms/factors that maintain humoral immunity, especially regarding the induction and maintenance of memory B cells over time. In Brazilian endemic areas, this is the first time that the profile of antibody responses and the occurrence of antigen-specific memory B cells (MBC) against P vivax were investigated during acute malaria and up to six months after parasite clearance. For this, we selected two peptides, PvAMA-1(S290-K307) and PvMSP-9(E795-A808) , which represent the apical membrane antigen-1 and merozoite surface protein-9 of P vivax, respectively. Both peptides were previously described as containing linear B-cell epitopes. Our findings were as follows 1-both peptides were recognized by IgG antibodies at a high frequency (between 24% and 81%) in all study groups; 2-in the absence of infection, the IgG levels remained stable throughout 6 months of follow-up; and 3-PvAMA-1(S290-K307) and PvMSP-9(E795-A808) -specific MBCs were detected in all individual groups in the absence of reinfection throughout the follow-up period, suggesting long-lived MBC. However,
