Plasma concentrations of tafenoquine, a new long-acting antimalarial agent, in Thai soldiers receiving monthly prophylaxis

We measured plasma tafenoquine concentrations in Thai soldiers given a monthly regimen of tafenoquine to determine whether these concentrations adequately suppressed malarial infections on the Thai- Cambodian border. After receiving a treatment course of artesunate and doxycycline, 104 male soldiers were administered a loading dose of tafenoquine ( 400 mg daily for 3 days), followed by tafenoquine monthly ( 400 mg every 4 weeks) for 5 months. Consecutive monthly mean ( +/- standard deviation) trough plasma tafenoquine concentrations were 223 +/- 41, 127 +/- 29, 157 +/- 51. 120 +/- 24, and 88 +/- ng/ mL. Only 1 soldier developed malaria during the study. At the time of malaria diagnosis, his plasma tafenoquine concentration was 40 ng/ mL, which was similar to 3- fold lower than the trough concentrations of the other soldiers. Although low tafenoquine concentrations appear to be uncommon, additional investigations are needed to determine the relationship between plasma tafenoquine concentrations and suppression of malaria.

Influence of body iron store status and cigarette smoking on cadmium body burden of healthy Thai women and men

The influence of cigarette smoking, body iron store status and gender on cadmium (Cd) body burden was examined in a group of 197 healthy Thais with overall mean age of 30.5 year (19-47 year). The lowest, geometric mean, and the highest urinary Cd excretion rate was 0.04, 0.46 and 3.84 mug/g creatinine, respectively. The prevalence of low iron stores (serum ferritin

Food and nutrient consumption patterns in third trimester Thai-Muslim pregnant women in rural Southern Thailand

The aims of this study were to determine food and nutrient intakes and the socio-economic factors influencing food and nutrient intakes of rural Thai-Muslim women in the third trimester of pregnancy. The study was conducted in Pattani province, Thailand, where 166 women were interviewed between 32 and 40 weeks gestation. A questionnaire. including a Food Frequency Questionnaire was used. Data on food items were compiled into the five basic Thai food groups, and food intakes were computed into macro and micro-nutrients. Mean weight intake of each of the five groups was below the recommended level for pregnant Thai women. Mean intake of niacin, vitamin A (RE) and vitamin C were above the recommended Thai level. Thiamin, calcium. phosphorus and iron intakes were lower than 50% of recommended levels. Intakes of the five food groups were not associated with socio-economic status, although total non-haem iron intake was associated with level of education. Under-consumption of food and nutrients among pregnant women in the study area was due to poor education. poverty and food availability. Integrated strategies should be considered to promote increased intakes to meet nutrient recommendations.

Eating disorder attitudes and psychopathology in Caucasian Australian, Asian Australian and Thai university students

Objective: To examine eating disorder attitudes and psychopathology among female university students in Australia and Thailand. Method: Participants were 110 Caucasian Australians, 130 Asian Australians and 101 Thais in Thailand. The instruments included the Eating Attitudes Test (EAT) and the Eating Disorders Inventory (EDI). Results: Eating disorder attitudes and psychopathology scores in the Thai group were found to be highest. The Asian Australian group did not have significantly higher scores on the EAT-26 than the Caucasian Australian group, but had higher scores in some subscales of the EDI-2. That the Thai group had the highest scores in susceptibility to developing an eating disorder and eating disorder psychopathology may be partially explained in sociocultural terms, with pressure to be thin more extreme in Thailand than in Australia. The evidence suggested that unhealthy eating disorder psychopathology is not limited to Western societies but is already present in Thai and other Asian societies.
