Background: Nutrition status among girls is becoming a severe concern for preventing undernutrition in their future pregnancy. Since they experience many physical changes during adolescence, some girls will feel dissatisfied with their own body. This feeling may lead to negative body image, which is a long time will impact health status. The research aimed to facilitate psychoeducation and analyze the improvements towards the senior high school girls’ perception of body image in Palembang.Method: A quasi-experimental study design was employed in the research with a non-equivalent control group. Participants were selected using purposive sampling, divided into intervention (n=18) and control (n=19) groups. All steps of the research were carried out online because of pandemic COVID-19. The questionnaire was given via Google form, while the three psychoeducation sessions were given through Zoom Meetings. Data were analyzed using Paired T-test (intervention) and Wilcoxon Signed Rank Test (control).Results: Most of the participants are 16 years old (40%), first-grade students (46%), and go to public school (67%). The mean score of both groups is decreased, which indicate their perception of body image is changed positively. However, there was no significant mean difference of the perception before and after treatment, either intervention (p-value 0.632) or control group (p-value 0.494). By the psychoeducation session, some participants already tried to share their feelings and problems related to their bodies, mostly originating from negative opinions given by peers. Girls should be motivated to love themselves through psychoeducation sessions with longer duration or more frequency to generate a positive body image.

This research aimed to determine the effectiveness of picture in storybook reading to increase kindness in children. This research involved 31 children aged 5-6 years; they were taken from the kindergarten in Bandung as the participants. The intervention was done by reading eight picture books in eight days. The kindness was measured using a measurement instrument created by the researcher, in the form of nine coloured cards that described the behaviour of kindness. The measurement was also done by seeing through the kindness tree and observation sheets that filled out by the teacher. The data analysis using the Wilcoxon Signed-rank test shows a significant difference in the average score of kindness (p<0,05) before and after picture storybook reading. Two weeks after the intervention, the improvement on all kindness behaviours with the post-test score is greater than pre-test score that still can be found. Observation through kindness tree and observational sheets shows the same result.

ABSTRACT Adult AIDS Clinical Trials Group 5043 examined pharmacokinetic (PK) interactions between amprenavir (APV) and efavirenz (EFV) both by themselves and when nelfinavir (NFV), indinavir (IDV), ritonavir (RTV), or saquinavir (SQV) is added. A PK study was conducted after the administration of single doses of APV (day 0). Subjects (n = 56) received 600 mg of EFV every 24 h (q24h) for 10 days and restarted APV with EFV for days 11 to 13 with a PK study on day 14. A second protease inhibitor (PI) (NFV, 1,250 mg, q12h; IDV, 1,200 mg, q12h; RTV, 100 mg, q12h; or SQV, 1,600 mg, q12h) was added to APV and EFV on day 15, and a PK study was conducted on day 21. Controls continued APV and EFV without a second PI. Among subjects, the APV areas under the curve (AUCs) on days 0, 14, and 21 were compared using the Wilcoxon signed-rank test. Ninety-percent confidence intervals around the geometric mean ratios (GMR) were calculated. APV AUCs were 46% to 61% lower (median percentage of AUC) with EFV (day 14 versus day 0; P values of <0.05). In the NFV, IDV, and RTV groups, day 21 APV AUCs with EFV were higher than AUCs for EFV alone. Ninety-percent confidence intervals around the GMR were 3.5 to 5.3 for NFV (P < 0.001), 2.8 to 4.5 for IDV (P < 0.001), and 7.8 to 11.5 for RTV (P = 0.004). Saquinavir modestly increased the APV AUCs (GMR, 1.0 to 1.4; P = 0.106). Control group AUCs were lower on day 21 compared to those on day 14 (GMR, 0.7 to 1.0; P = 0.042). African-American non-Hispanics had higher day 14 efavirenz AUCs than white non-Hispanics. We conclude that EFV lowered APV AUCs, but nelfinavir, indinavir, or ritonavir compensated for EFV induction.
