Cogon grass (Imperata cylindrica/I. cylindrica) of the Gramineae family is found abundantly in nature, and the roots of this plant possess several beneficial biological properties. The present study aimed to isolate and identify flavonoid compounds from cogon grass roots and examine their potential as hypocholesterolemic agents. The flavonoid compound was isolated using a maceration method, followed by gravity column chromatography until a pure compound was obtained. The molecular structure of the isolated compound was determined using 1H‑nuclear magnetic resonance (NMR) and 13C‑NMR spectroscopy. An in vivo lipid‑lowering test used a randomized post‑test only control group experimental design in rats with hypercholesterolemia. The animals were divided into four groups: K0, negative control; K1, positive control; K2, ethanol extract treated group; and K3, ethyl acetate fraction treated group, and the lipid profiles were examined at the end of the study. The isolated compound, 7,3',5'‑trimethoxyflavonol, was collected in yellow powder form; was shown to be a flavonoids and was comprised of 18 carbon atoms and 16 hydrogen atoms. In vivo tests demonstrated that 15 mg/200 g body weight (BW) of an ethanol extract significantly lowered total cholesterol levels (P=0.001) but did not lower low‑density lipoprotein (LDL) (P=0.109) and high‑density lipoprotein (HDL) levels (P=0.003). The fraction of ethyl acetate administered at 15 mg/200 g BW was capable of lowering the total cholesterol levels significantly (P=0.002) and lowered LDL levels (P=0.006) but was unable to increase HDL levels (P=0.190). The in vivo tests showed that the ethyl acetate fraction of I. cylindrica reduced total cholesterol and LDL levels more effectively than the ethanol extract, but did not affect HDL levels in rats with hypercholesterolemia.
Previous observational studies suggested that hepatitis B virus (HBV) preS mutation plays an important role in the existence of HBV‐related hepatocellular carcinoma (HCC). However, the results are still debatable. With an increasing number of studies about this topic, this study employed a meta‐analysis to identify the association between HBV preS mutation and HCC risk. We searched for eligible studies from PubMed, ProQuest, CINAHL, ScienceDirect and Springer databases to assess the association between HBV mutation and HCC risk. This meta‐analysis was conducted using RevMan 5.3 to provide pooled estimate for odds ratio (ORs) with 95% confidence intervals (95% CIs). Twenty‐one clinical studies were included in this meta‐analysis study which consisted of 1738 participants with HBV‐related HCC and 3740 HBsAg‐positive patients without HCC. All studies used samples of Asian population. PreS deletion was the most common mutation found in all studies. We found that ORs of HBV overall preS deletion was associated with HCC (OR = 3.28; 95% CI = 2.32‐4.65; P < .00001; random‐effects model). Each preS1 and preS2 deletion was associated with increased risk of HCC, with OR 2.42 (95% CI = 1.25‐4.68, P = .008) and 3.36 (95% CI = 2.04‐5.55, P < .00001), respectively. PreS2 start codon mutation was also significantly associated with HCC risk (OR = 2.47; 95% CI: 1.15‐5.27; P = .02; random‐effect model). The result of this meta‐analysis suggested that HBV preS deletion (all, preS1 and preS2) and preS2 start codon mutation might contribute to the increased risk of HBV‐related HCC.
Objective: The role of Mycobacterium tuberculosis complex (MTBC) species in tuberculosis (TB) infection in human is still questioned. The aim of this study was to determine whether M. tuberculosis and M. bovis is associated with apoptosis and necroptosis by measuring the expression of specific signaling pathways components (Fas-associated protein with death domain (FADD) and receptor interacting protein 3 (RIP3)), and the level of apoptosis. Results: We recruited 30 patients with pulmonary TB; 24 patients were infected with M. tuberculosis Beijing strain and six patients with M. bovis BCG strain. M. tuberculosis-infected patients were more likely to have severe lung damage compared to those infected with M. bovis (odds ratio [OR] 7.60; 95% confidence interval [CI] 1.07–54.09). M. tuberculosis infection was associated with lower expression of FADD and lower apoptosis level of macrophages compared to M. bovis. No significant different of RIP3 between MTBC species groups. In conclusion, M. tuberculosis Beijing strain was associated with severe pulmonary damage, inhibited FADD expression and reduced apoptosis level of macrophages derived from pulmonary TB patients. This suggests that the M. tuberculosis Beijing strain is potentially to be used as determinant of disease progressivity and tissue damage in TB cases.

Background: Type 1 diabetes mellitus (T1DM) is the most common chronic disease in children, with several severe short and long-term complications. Glycemic control is an important aspect of diabetes management with the most influential factor being compliance with self-monitoring blood glucose (SMBG). Mostly, in Indonesia, the finger stick devices as a glucose monitoring tool were frequently used. About 20% of children follow the recommendation to measure blood glucose four to six times daily. Methods: This is a single center, cross-sectional study that was conducted between July–November 2022. The Population is children with T1DM at the Pediatric Outpatient Clinic of Dr. Soetomo Hospital, Surabaya, Indonesia. Children with T1DM aged 4– 18 years were enrolled using consecutive sampling. A compliance questionnaire was used to assess SMBG. Psychosocial conditions were assessed using the Pediatric Symptom Checklist 17, and medication adherence was evaluated using the Adherence to Refills and Medications Scale for Diabetes (ARMS-D). Pearson correlation and linear regression were employed for statistical analyses using Statistical Package for Social Sciences version 21.0, with p < 0.05 indicating statistical significance. Results: A total of 36 children were included in this study. SMBG frequency over 4x per day was significantly associated with increased medication adherence as measured by the ARMS-D score (p = 0.012). Higher SMBG frequency was also correlated with decreased HbA1c (p = 0.014, r = 0.406) and nutritional status (p = 0.031, r = 0.360). Less than 50% of the patients in Indonesia adhered to the recommended guidelines for SMBG (ie, ≥ 4 times per day). Conclusion: Higher SMBG frequency was correlated with better glycemic control. This finding suggests the need for further support in conducting SMBG based on the national guideline. However, due to it being conducted in a single center, we suggest increasing the sample size or conducting multi-centre collaborations in future studies. Originality/Value: By specifically investigating the relationship between adherence to self-monitoring of blood glucose (SMBG) and glycemic control in children with type 1 diabetes mellitus (T1DM), our study represents a novel contribution to the field of pediatric diabetes management in Indonesia. While previous research has explored similar relationships in other populations, our study focuses exclusively on the unique context of Indonesia, where rates of adherence to SMBG in pediatric patients have not been well studied and are relatively low compared to global standards.
Background: More than 40 genes influence the progression of type 1 diabetes mellitus (T1DM), including human leukocyte antigen (HLA) alleles. Different HLA genotype patterns result in diverse rates of T1DM development. HLA class II DR, DQ, and DP vary among different populations and ethnicities. Data on HLA polymorphism in T1DM in Indonesia are lacking. Therefore, this study was designed to evaluate the gene polymorphism of HLA-DQA1 and HLA-DQB1 in Indonesian children with T1DM. Patients and Methods: In this study, 31 patients with T1DM and 31 controls were enrolled from April 2020 to April 2021. This study was conducted at Dr. Soetomo Hospital, Indonesia. We evaluated the gene polymorphism of HLA-DQA1 and HLA-DQB1 using polymerase chain reaction–restriction fragment length polymorphism. The primers used were as follows: for HLA-DQA1, DQAS34: 5ʹ-GGTGTAAACTTGTACCAG-3ʹ (forward) and DQAA261: 5ʹ-ATTGGTAGCAGCGGTAGA-3ʹ (reverse); for HLA-DQB1, DQBS43: 5ʹ-TGCTACT- TCACCAA(C/T)GGG-3ʹ (forward) and DQBA249: 5ʹ-GTAGTTGTGTCTGCA (C/T)AC-3ʹ (reverse). Results: The most common HLA-DQA1 subtype in the T1DM group was 0101/0102 accounting for 67.6%, and 01/03 and 02/03 were found in the T1DM group only. Meanwhile, the most common HLA-DQB1 subtype in the T1DM group was 0301, accounting for 54.8%. Most subjects in this study were Javanese. Conclusion: HLA-DQA1 0101/0102 and HLA-DQB1 0301 were commonly found in Indonesian children with T1DM.
