My previous career was as a manager in a fraud detection team, however I have now returned to fulltime study (psychology) in search of more fulfilling daily work and having more time for EA-related interests.
I am trying to help regrow EA @ Macquarie University.
Outside of study and group organising, I have been spending time researching antimalarial bed nets and intend to continue to do so for the indefinite future. However, I am keenly interested in most EA-mainstream cause areas: global poverty, animal welfare, improving our long-term prospects and/âor general movement building.
Thank you Nick. A lot of interesting information for an accessible 5-minute read.
As we speak, artesunate still cures over 99.9% of malaria casesâif a little slower than before. But we donât know when that will become 99%, then only 90% at which point weâll need alternatives.
Iâm trying to get my head around the meaning of these numbers. The questions below are largely academic (no goal in mind), surely difficult, and likely dumb, so please feel no pressure to devote valuable time :)
(1) Are these cure rates in reference to the outcome of Therapeutic Efficacy Studies (TES) as described in this WHO document (Section 4.1) and where the outcome is an âadequate clinical and parasitological response (ACPR)â (p. 11 of that document)?
If it is:
(2) What is your best estimate for how often ACPR would be âachievedâ without treatment?* I believe this would be difficult to answer. My estimate right now based off close to zero rationale: 4% (95% CI: 0.25% â 60%).
(3) What would you estimate the effect on saving a childâs life would be in a drop from 100% to 90%?* Maybe can be quantified as (but you likely have a better way): For every 1000 children who come into a clinic for malaria treatment, how many would survive if (a) artesunate is administered versus if (b) no treatment was provided, given (i) 100% efficacy versus (ii) 90% efficacy.
My suspicion is that the ratio of p(ACPR | artesunate) : p(ACPR | no treatment) underestimates the effect on mortality (and severe malaria) due to the binary outcome measure not capturing benefits from artesunate reducing without eliminating the degree of parasitaemia(?)
Thanks again.
