However, factors determining the intended outcome (weight gain) have not been properly investigated. The main objective of the study was to assess improvement in body mass index and to identify its determinant factors. A retrospective cohort study design was conducted. Cluster sampling was employed to select health facilities in which the service was provided in the region. Of the 44 health facilities, nine were selected using lottery method, and all patients receiving the care in these health institutions were included in the study. Using tailored structured checklist, data were collected, organized and cleaned. Using paired T-test existence of difference between the mean of body mass index at admission and at 3rd visit was measured. Finally analysis of association between some selected independent variables with the outcome variable was done using logistic regression model at 95% CI and p 2). Paired T-test revealed that there was a statistically significant difference between mean of body mass index at admission and at the 3rd visit. Good ready-to-use therapeutic food treatment adherence (AOR 11.145;95% CI 6.556, 18.946), moderate acute malnutrition at admission (AOR 6.71;95% CI 2.618, 17.195), good ART adherence (AOR 2.136;95% CI, 1.269, 3.595) and being male (AOR 1.73;95% CI 1.052, 2.850) have a statistically significant contribution for body mass index improvement. The study identifies factors that determine gain in body mass index among AIDS patients on ready-to-use therapeutic food. However, although the study revealed a statistically significant difference between body mass index during enrolment, and after three months, we disagreed with the right and left utilization of imported food because of lack of sustainability, and aid dependency. We rather recommend interventions that encourage households to produce food with similar outcomes from locally available food staff.展开更多

We observed the change of WLI and bispectral index （BIS） in patients regain of consciousness （ROC） in the absence of frontalis electromyographic （EMG） interference. The aim of this study was to compare the ability of WLI and BIS for reflecting ROC in patients undergone surgery. Methods Twelve patients who were scheduled for maxillofacial surgeries were enrolled in the study. BIS and WLI values were monitored continually. After being given midazolam and remifentanil, patients were asked to squeeze the investigator＇s hand ever 30 seconds. Patients were continuously given propofol until loss of consciousness （LOC1）. Tunstalrs isolated forearm technique was used to test the surgical consciousness in patients. After total muscle relaxation endotracheal intubations were performed, and the patients were connected to a ventilator. Then, propofol was withdrawn until the patients showed regain of consciousness （ROC1） and an awareness reaction. After the command test, patients were readministered with propofol until loss of consciousness （LOC2）. After surgery, all of the sedatives were withdrawn, and the patients were let to regain consciousness （ROC2）, Results The BIS values of twelve patients at ROC1 after using muscle relaxant were much lower than those at LOC1 and ROC2 without using muscle relaxant, showing statistical significance （P 〈0.05）. Meanwhile, the WLI values of twelve patients at ROC1 after using muscle relaxant were much higher than those at LOC1 and equal to ROC2 without using muscle relaxant, showing statistical significances （P 〈0.05） between ROC1 and LOCI. Conclusions This study showed that under muscle relaxation or facial paralysis, when there is no EMG signal, BIS can not accurately reflect regain of consciousness in surgical patients, but WLI can reflect it accurately. So WLI may have advantages for reflecting state of consciousness in surgical patients.展开更多
