TL;DR: Higher, more frequent, or prolonged dosage regimens should now be evaluated in very young children, particularly if malnourished, and in patients with hyperparasitemia, as well as patients in very low transmission intensity areas with emerging parasite resistance.
Abstract: Background: Achieving adequate antimalarial drug exposure is essential for curing malaria. Day 7 blood or plasma lumefantrine concentrations provide a simple measure of drug exposure that correlates well with artemether-lumefantrine efficacy. However, the 'therapeutic' day 7 lumefantrine concentration threshold needs to be defined better, particularly for important patient and parasite sub-populations. Methods: The WorldWide Antimalarial Resistance Network (WWARN) conducted a large pooled analysis of individual pharmacokinetic-pharmacodynamic data from patients treated with artemether-lumefantrine for uncomplicated Plasmodium falciparum malaria, to define therapeutic day 7 lumefantrine concentrations and identify patient factors that substantially alter these concentrations. A systematic review of PubMed, Embase, Google Scholar, ClinicalTrials.gov and conference proceedings identified all relevant studies. Risk of bias in individual studies was evaluated based on study design, methodology and missing data. Results: Of 31 studies identified through a systematic review, 26 studies were shared with WWARN and 21 studies with 2,787 patients were included. Recrudescence was associated with low day 7 lumefantrine concentrations (HR 1.59 (95 % CI 1.36 to 1.85) per halving of day 7 concentrations) and high baseline parasitemia (HR 1.87 (95 % CI 1.22 to 2.87) per 10-fold increase). Adjusted for mg/kg dose, day 7 concentrations were lowest in very young children (98 % cure rates (if parasitemia <135,000/μL). Conclusions: Current artemether-lumefantrine dosing recommendations achieve day 7 lumefantrine concentrations ≥200 ng/ml and high cure rates in most uncomplicated malaria patients. Three groups are at increased risk of treatment failure: very young children (particularly those underweight-for-age); patients with high parasitemias; and patients in very low transmission intensity areas with emerging parasite resistance. In these groups, adherence and treatment response should be monitored closely. Higher, more frequent, or prolonged dosage regimens should now be evaluated in very young children, particularly if malnourished, and in patients with hyperparasitemia.

TL;DR: Examining some key issues related to the international migration of health workers and to discuss strategic approaches to managing migration are examined.
Abstract: Of the 175 million people (2.9% of the world's population) living outside their country of birth in 2000, 65 million were economically active. The rise in the number of people migrating is significant for many developing countries because they are losing their better-educated nationals to richer countries. Medical practitioners and nurses represent a small proportion of the highly skilled workers who migrate, but the loss for developing countries of human resources in the health sector may mean that the capacity of the health system to deliver health care equitably is significantly compromised. It is unlikely that migration will stop given the advances in global communications and the development of global labour markets in some fields, which now include nursing. The aim of this paper is to examine some key issues related to the international migration of health workers and to discuss strategic approaches to managing migration.

TL;DR: The results suggest that zoonotic transmission of Giardia infections between humans and dogs does not occur frequently in these communities, and suggest a new G. duodenalis subgroup.
Abstract: A polymerase chain reaction-based method for genotyping Giardia duodenalis isolates using a polymorphic region near the 5' end of the small subunit ribosomal (SSU) RNA gene is described. Analysis was performed using Giardia cysts purified directly from feces. Isolates were collected from humans and dogs living in isolated Aboriginal communities where Giardia infections are highly endemic. This is the first report of the genetic characterization of Giardia from dogs and humans living in the same locality. Comparison of the SSU-rRNA sequences from 13 human and 9 dog isolates revealed 4 different genetic groups. Groups 1 and 2 contained all of the human isolates, whereas groups 3 and 4 consisted entirely of Giardia samples recovered from dogs. One dog sample contained templates from both groups 2 and 3. These results suggest that zoonotic transmission of Giardia infections between humans and dogs does not occur frequently in these communities. The dog-associated SSU-rRNA sequences have not been reported before, suggesting a new G. duodenalis subgroup. A genetic basis for the differences observed between the groups was supported by sequence analysis of 9 in vitro cultured isolates that were placed into the same genetic groups established by enzyme electrophoresis.

TL;DR: The prevalence of reduced vision is very low in school-age children in Nepal, most of it because of correctable refractive error, and the prevalence of myopia is higher for more recent birth cohorts.
