Abstract

Background Clot waveform analysis can be used to evaluate clot formation profiles. This waveform can be obtained from activated partial thromboplastin time (APTT) assays without additional reagents and shows different patterns in hemophilia patients with coagulation factor VIII (F VIII) deficiency or abnormality. Objective To determine the clot wave pattern and its process in clot formation phases (pre-coagulation, coagulation, and post-coagulation) in normal and hemophilia A subjects, analyze for possible correlations between clot wave parameters and F VIII activity, and obtain the pattern of coagulation curves in hemophilia subjects as a step to assess clot waveform analysis as a possible screening tool for hemophilia. Methods In this cross-sectional study, we performed clot wave analysis in 145 adult and pediatric subjects with hemophilia to obtain the clot wave pattern in this condition. Clot wave analysis was also done in 160 subjects with normal hemostasis to obtain reference clot wave parameters. Results In this study, the starting point of coagulation phase in normal subjects was between 30-40 seconds, with a shorter pre-coagulation phase and steeper slope. Hemophilia patients had a longer pre-coagulation phase and flatter slope, especially in severe hemophilia A patients, who had longer and more variable coagulation starting points (P<0.001). The absolute values of maximum coagulation velocity (Min1), maximum coagulation acceleration (Min2), and maximum coagulation deceleration (Max2) of hemophilia A patients were also lower than those of normal hemostasis patients, with lower absolute value seen in severe than in mild-moderate hemophilia A patients. A moderate correlation was found between Min1, Min2, and Max2 with F VIII activity (P<0.001). Conclusion Clot wave analysis may be considered as a method for screening hemophilia patients to distinguish mild-moderate and severe hemophilia A patients in health facilities that lack the ability to perform F VIII assays.

Abstract

Background Correct complementary feeding practice can be a challenge for mothers. Our complementary feeding practice module provides practical information regarding evidence-based complementary feeding practices. Objective To assess the effect of educational intervention using the complementary feeding practice module on maternal knowledge and behavior and to compare the effect of video vs. printed delivery of the module. Methods This open label randomized controlled trial included mothers with babies aged 4 to 8 months in Pontianak, West Kalimantan, Indonesia, who engaged in complementary feeding. Subjects were randomized into an intervention group that received a printed booklet of the module, an intervention group that received a video of the module, or a control group that received the standard Indonesian mother and child health (MCH) handbook. Maternal knowledge and behavior regarding complementary feeding practice were assessed before and after the educational intervention using the PI-MPASI questionnaire. Results Of 360 mothers screened, 241 subjects were randomized into the video education group (n=76), the printed education group (n=84), and the control group (n=81). A total of 212 subjects completed the study by submitting both the pre- and post-test: 66 in the video group, 74 in the printed booklet group, and 72 in the control group. Subjects who received the module (video or printed) had significantly higher knowledge and behavior scores than those in the control group. Video education was associated with a greater increase in behavior score than printed education and control. The outcome of video education was not influenced by maternal educational level. Conclusion  Education using a simple and practical video or printed module improves maternal knowledge and behavior in complementary feeding practices. Video education is associated with a greater improvement in maternal complementary feeding behavior than printed education.
