MATERIALS AND METHODS: A cross-sectional design was used in this study involving 245 participants of type 2 diabetes mellitus (T2DM) was conducted at a Kitamura Wound Care Clinic, PKU Muhammadiyah, located in Pontianak, West Kalimantan, Indonesia, between September 2022 and February 2023. The Kruskal-Wallis test was used to assess the relationship between the foot care practices and infection status. A linear regression test to examine the independent risk factors.
RESULTS: Wounds' characteristics regarding foot care practice group were significantly including more than 5 months wound heal from previous wounds (p = 0.045), the percentage of wound site on dorsal was higher in the foot care practice group (p < 0.001), the percentage had no deformity feet was higher in the foot care practice group (p < 0.001), the percentage had no previous amputation feet was higher in the foot care practice group (p < 0.001). Also, the percentage had grade three was higher in the foot care practice group (p < 0.001), the percentage had grade three was higher in the foot care practice group (p < 0.001), and the percentage had mild infection status was higher in the foot care practice group (p < 0.001). The predictors of diabetic foot infection were Wagner and SHID classification and foot care (p < 0.001, p < 0.001, and p < 0.01) respectively.
CONCLUSION: This study demonstrated that foot-care behaviour in diabetic patients in Indonesia is poor. In addition, this study also has shown Wagner grading, SHID grading, and foot-care are predictors of infection in recurrent DFUs.
DESIGN AND METHOD: This study was conducted using a cross sectional study with 75 students collected randomly from four junior high schools in Jakarta. PM2.5 and NO2 were measured in classrooms and school yards. The schools were categorized based on the exposure level of PM2.5 and NO2 in classrooms. Superoxide dismutase (SOD) and reduced glutathione (GSH) were examined from the blood sample. All students were interviewed with questionnaires to determine upper respiratory tract infection, smoking family members, mosquito repellent usage, and dietary supplement consumption.
RESULTS: Mean concentration of indoor PM2.5 and NO2 were 0.125±0.036 mg m-3 and 36.37±22.33 µg m-3, respectively. The schools which located near to highway showed lower PM2.5 and higher NO2 level indicated the emission of traffic activity. Mean activity of SOD was 96.36±50.94 U mL-1 and mean concentration of GSH was of 0.62±0.09 µg mL-1. Most of the students reported upper respiratory tract infection history, smoking family member, use mosquito repellent at home, and do not consume dietary supplement.
CONCLUSION: The level of oxidative stress markers and the exposure categories of classroom PM2.5 and NO2 was not significantly different, however there were significant correlation with cigarette smoke and mosquito repellent at home. Nevertheless, the exposure of indoor PM2.5 and NO2 increased the risk of the exposure to cigarette smoke and mosquito repellent at home. Further study on the air pollution at school and home is needed to affirm association towards student's health and to design strategic control efforts.
