Background and Purpose: Quantification of hepatic virtual iron content (VIC) by using Multidetector Dual Energy Computed Tomography (DECT) has been recently investigated since this technique could offer a good compromise between accuracy and non-invasiveness for liver iron content quantification. The aim of our study is to investigate differences in VIC at different DECT time points (namely baseline and arterial, venous and tardive phases), identifying the most reliable and also exploring the underlying temporal trend of these values. Materials and Methods: Eleven patients who underwent DECT examination and were characterized by low liver fat content were included in this retrospective study. By using the Syngo.via Frontier–DE IronVNC tool, regions of interest (ROI) were placed on the VIC images at 3 hepatic levels, both in left and right liver lobes, at each DECT time point. Friedman’s test followed by Bonferroni-adjusted Wilcoxon signed-rank test for post-hoc analysis was performed to assess differences between DECT timepoints. Page’s L test was performed to test the temporal trend of VIC across the 4 examined timepoints. Results: For both liver lobes, Friedman’s test followed by Bonferroni-adjusted Wilcoxon signed-rank test revealed that VIC values differed significantly when extracted from ROIs placed at the 4 different timepoints. The Page’s L test for multiple comparison revealed a significant growing trend for VIC, from baseline acquisition to the fourth and last time point post-contrast agent injection. Conclusions: The extraction of hepatic VIC in healthy subjects was found to be significantly influenced by the DECT time point chosen for the extrapolation of the VIC values.

One of the nutritional problems that often occurs among adolescents is iron deficiency anemia. Especially for adolescent girls who have a higher risk of anemia than adolescent boys. Based on data from Riskesdas 2018, the prevalence of anemia in adolescents aged 15-24 years is 32%, meaning that there are still anemia problems in Indonesia that have not been resolved. The purpose of this community dedication activity is to provide education about iron deficiency anemia for adolescent girls using leaflet media. The target of this community dedication activity is adolescent girls aged 12-19 years in the JABODETABEK area. The community dedication activity is carried out online through the WhatsApp group due to the COVID-19 pandemic. There are 31 adolescent girls who participated in this community dedication activity. This community dedication activity consists of three stages including pretest, education with leaflets, and posttest. The amount and types of pretest and posttest questions are the same. The amount of questions given is 15 questions. The correct answer is given a score of 10 and the wrong one is given a score of 0. The level of knowledge of adolescent girls is categorized as 3 groups, which is less if the correct answer is <60%, sufficient if the correct answer is 60-80%, and good if the correct answer is >80%. Most of the adolescent girls are in the age range of 17-19 years (54.8%). The results showed that there was an increase in knowledge about iron deficiency anemia in adolescent girls. The results of the Wilcoxon signed rank test showed significantly different pretest and posttest results (p-value = 0.000), so it can be concluded that providing education using leaflets can help increase knowledge of iron deficiency anemia for adolescent girls.Salah satu masalah gizi yang sering terjadi pada kalangan remaja yaitu anemia defisiensi besi.

Background: Infant tongue-tie can cause breastfeeding problems, which may be improved by frenotomy. However, controversy exists among the medical community. Research aim: To examine the influence of frenotomy on infants with posterior ankyloglossia, by quantifying the changes in breastfeeding and maternal nipple pain using standardized tools. Methods: Newborns ( N = 30) below 12 weeks of age were recruited from the Herzl–Goldfarb Breastfeeding Clinic between April 2014 and April 2015. Diagnosis of posterior ankyloglossia was made clinically. Frenotomy was performed. Mothers received breastfeeding counseling before and after the procedure. Pain and breastfeeding were assessed before the procedure, immediately after the procedure, and after 2 days, 7 days and 14 days. Breastfeeding was assessed using the LATCH Tool and by subjective questioning. Maternal nipple pain was assessed using the Numeric Rating System. Results: No complications were reported with frenotomy. There was a significant improvement in LATCH score immediately post-frenotomy, with an increase in median scores from 7.5 to 8.5 ( p < .0001, Wilcoxon signed rank test). There was a significant decrease in median pain score immediately post-frenotomy, from 3.0 on the left nipple and 3.25 on the right nipple, to 0 bilaterally ( p < .0001, Wilcoxon signed rank test). Subjective improvement in breastfeeding was reported by 90% of mothers immediately after frenotomy and 83% of mothers at Day 14. Conclusion: Frenotomy for posterior ankyloglossia may improve breastfeeding and nipple pain.

O objetivo deste artigo foi avaliar se as fusões e aquisições de empresas brasileiras resultaram em sinergias operacionais e criaram valor para os acionistas. Além disso, buscou-se identificar a existência de correlação entre três medidas utilizadas de criação de valor, visando justificar o seu uso como proxies alternativas do desempenho empresarial. Assim, realizou-se um estudo descritivo que utizou os testes Wilcoxon Signed Rank Test e do Rank Test para analisar dados trimestrais de 72 processos de F&A's ocorridos entre jan./96 e dez./04. As F&A's estudadas resultaram em sinergias operacionais e na maximização do valor de mercado das empresas pesquisadas, e, aparentemente, da riqueza dos acionistas. Foram, ainda, encontradas correlações significativas entre as variáveis de criação de valor.
