Twenty-three patients were found to be infected with P. vivax, 19 with P. falciparum and five with both by thin smear examination. Blood samples were divided into two TGF-beta pathway groups: Group I consisted of patients who were positive for infection by microscopic examination, and Group II consisted of those who showed symptoms, but were negative in microscopic examination. In P. falciparum, IgG against the blood stage antigen in Group I (80.8%) was higher than in Group II (70.0%). In P. vivax, IgG against the blood stage antigen in Group I (53.8%) was higher than in Group II (41.7%). However, the positivity rate of the PvCSP VK210 subtype in Group II (40.0%) was higher than in
Group I (23.1%). Similarly for the PvCSP VK247 subtype, Group II (21.7%) was higher than that for Group I (9.6%). A similar pattern was observed in the ELISA using Pvs25 and Pvs28: positive rates of Group II were higher than those for Group I. However, those differences were not shown significant in statistics.
Conclusions: The positive rates for blood stage antigens of P. falciparum were higher in Group I than in Group II, but the positive rates for antigens of other stages (PfLSA-1 and -3) showed opposite results. Similar to P. falciparum, the positive rate of pre-blood GDC 0068 stage (CSP VK210 and 247 subtype) and post-blood stage (Pvs25 and 28) antigens of P. vivax were higher in Group II than in Group I. Therefore, sero-diagnosis is not helpful to discriminate
between malaria patients and symptomatic individuals during the epidemic season in Myanmar.”
“Background: Cross-sectional data indicate an inverse relation between breakfast consumption and child weight. It has been suggested that skipping breakfast may adversely affect appetite in children, which could lead to overeating later in the day.
Objective: The aim of this study was to test the effects
of consuming breakfast compared with omitting breakfast on appetite ratings and energy intake at subsequent meals in 8- to 10-y-old children.
Design: Twenty-one children participated in 2 test visits during which they were served either a compulsory breakfast or no breakfast. On both visits, subjects were also served lunch, which was consumed ad libitum. Subjects rated their appetite throughout the morning; parents completed food records that captured children’s intake for the remainder of the day.
Results: There was no significant main effect of breakfast see more condition on energy intake at lunch (P = 0.36) or throughout the remainder of the day (P = 0.85). There was a significant main effect of breakfast condition (P = 0.04) on total daily energy intake, which indicated that on the day when the subjects did not eat breakfast, they consumed 362 fewer calories over the course of the day than when they did eat breakfast. On the day when no breakfast was served, subjects indicated that they were significantly hungrier, less full, and could consume more food before lunch than on the day when they did eat breakfast (P < 0.001).
