Non-communicable diseases (NCDs) are emerging rapidly. This manuscript reports on a pilot survey of NCDs at a primary healthcare level in a marginalised migrant population on the Thailand-Myanmar border in the face of declining rates of malaria. A retrospective audit of routine clinic (2004-2016) and NCD patient survey data (2014-2016) was conducted. The length of follow-up was assessed by Kaplan-Meier analysis. From July 2014 to July 2016, 238 migrant patients were on the NCD register. Hypertension (n = 80) and diabetes mellitus (n = 51) were the most common diagnoses. After the first consultation, 41% (95% confidence interval = 35-47%) were lost to follow-up by 30 days. NCD retention rates were low: 50% of registered patients were lost to follow-up by 80 (95% CI = 49-132) days. After this survey, a novel low-cost insurance scheme for the migrant community has been launched in this area. Development of new schemes involving patients, healthcare providers and funding support are required for improved and sustainable NCD care for marginalised populations. [ABSTRACT FROM AUTHOR]

Quinoline antimalarials cause drug-induced electrocardiographic QT prolongation, a potential risk factor for torsade de pointes. The effects of currently used antimalarials on the electrocardiogram (ECG) were assessed in pregnant women with malaria. Pregnant women with microscopy-confirmed parasitemia of any malaria species were enrolled in an open-label randomized controlled trial on the Thailand-Myanmar border from 2010 to 2016. Patients were randomized to the standard regimen of dihydroartemisinin-piperaquine (DP) or artesunate-mefloquine (ASMQ) or an extended regimen of artemether-lumefantrine (AL+). Recurrent Plasmodium vivax infections were treated with chloroquine. Standard 12-lead electrocardiograms were assessed on day 0, 4 to 6 h following the last dose, and day 7. QT was corrected for the heart rate by a linear mixed-effects model-derived population-based correction formula (QTcP = QT/RR 0.381 ). A total of 86 AL+, 82 ASMQ, 88 DP, and 21 chloroquine-treated episodes were included. No patients had an uncorrected QT interval nor QTcP of >480 ms at any time. QTcP corresponding to peak drug concentration was longer in the DP group (adjusted predicted mean difference, 17.84 ms; 95% confidence interval [CI], 11.58 to 24.10; P  < 0.001) and chloroquine group (18.31 ms; 95% CI, 8.78 to 27.84; P  < 0.001) than in the AL+ group, but not different in the ASMQ group (2.45 ms; 95% CI, -4.20 to 9.10; P  = 0.47) by the multivariable linear mixed-effects model. There was no difference between DP and chloroquine ( P  = 0.91). QTc prolongation resulted mainly from widening of the JT interval. In pregnant women, none of the antimalarial drug treatments exceeded conventional thresholds for an increased risk of torsade de pointes., (Copyright © 2021 Saito et al.)
