INTRODUCTION: Thrombocytopenia is a common complication in dengue that sometimes necessitates platelet transfusion. Immature platelet fraction (IPF) measures immature platelets that indirectly reflect thrombopoiesis and is helpful in predicting platelet recovery.
OBJECTIVES: This study aimed to evaluate the role of IPF% and identify its cut-off value in predicting platelet recovery in dengue patients with thrombocytopenia.
MATERIALS AND METHODS: Serial platelet count and IPF results were obtained from fifty-four confirmed dengue patients with platelet count <50x109 /L. Median peak IPF% and number of patients with platelet recovery were determined. Receiver operating characteristic (ROC) curve is generated to identify the IPF% cut-off value to predict platelet recovery.
RESULTS: Median peak IPF% among dengue patients was 12.15% with 83.3% of them achieving platelet recovery after reaching the peak IPF%. There was a significant difference between median IPF% on day one of admission with peak IPF% among dengue patients. ROC curve analysis showed IFP% of 10.55% can be used to predict platelet recovery with a sensitivity of 69% and a specificity of 67%.
CONCLUSION: IPF% is a reliable and useful parameter in predicting platelet recovery in dengue patients. This would assist the clinician in managing dengue patients especially those with severe thrombocytopenia without giving unnecessary platelet transfusion.

Drug treatment and rehabilitation programs are one of the initiatives to alleviate the global epidemic of drug addiction. The efforts were undertaken by everyone, particularly the government. However, the rising number of drug relapses among patients or clients ponders the effectiveness of the drug treatment and rehabilitation programs implemented in the country. This paper aims to study the drug relapse prevention initiatives and the effectiveness of the center in dealing with drug addiction issues. A case study of 4 drug treatment and rehabilitation centers, namely Cure & Care 1Malaysia Clinics in Selangor, Malacca, Penang, and Kelantan, was selected. In-depth interviews were conducted with 37 participants-26 clients and 11 providers, and the data were analyzed using thematic analysis and NVivo version 12. The findings indicate that relapse prevention initiatives are a signal for the effectiveness of the center to reduce drug relapse cases. The implementation of drug treatment and rehabilitation programs was effective based on key aspects consisting of (1) knowledge and life skills learned; (2) staff reception; (3) individual changes; and (4) client acceptance. Therefore, by experiencing relapse prevention activities, it helps to improve the effectiveness of the implementation of drug treatment and rehabilitation programs.
