Potential of Rambutan-Honey Antioxidants in Reducing Malondialdehyde Levels and Regenerating Hepatocyte Cells in Isoniazid-Rats Induced

Hepatotoxicity induced by prolonged administration of antituberculosis drugs such as isoniazid (INH) is associated with the production of free radicals. Rambutan-honey, rich in catalase enzyme, flavonoids, and vitamin C, exhibits antioxidant and immunomodulatory properties. This study purpose to assess the effect of rambutan-honey on malondialdehyde (MDA) levels and hepatocyte cell numbers in INH-induced rats. The research method using in vivo experimental study with a randomized posttest-only control group design. Thirty Wistar rats were divided into five groups: negative control(G1), positive control(G2), and three groups treated with rambutan-honey at doses of 250 mg/kgBW(G3), 500 mg/kgBW(G4), and 1000 mg/kgBW(G5). MDA levels were measured using the TBARS method on days 15 and 23, while hepatocyte cell numbers were assessed through histopathological examination using Hematoxylin-Eosin. Data were analyzed using One-Way ANOVA followed by Post-Hoc test. This study revealed that rambutan-honey at doses of 250, 500, and 1000 mg/kgBW significantly reduced MDA levels compared to controls, with a simultaneous increase in hepatocyte cell numbers (p=0.001). The conclusion of this research is the potential of rambutan-honey as an antioxidant and hepatoprotective agent, possibly mediated by its flavonoid content, which may stimulate superoxide dismutase activity akin to catalase enzyme and vitamin C.

Impact of Age Initiation and Duration of Hemodialysis on Impaired Cognitive Function Experienced by Chronic Kidney Disease (CKD) Patients

The prevalence of people with chronic kidney disease (CKD) in Indonesia increases with age. Various complications to death can occur in CKD patients, one of which is impaired cognitive function. In addition, end-stage CKD treatment options, such as hemodialysis, further increase the risk of complications of cognitive impairment in CKD patients. About 10%-40% of CKD patients experience a decline in cognitive function. This study aims to determine the factors that influence the occurrence of cognitive impairment in hemodialysis patients. This study was conducted at Mohammad Hoesin Hospital Palembang in October-November 2022. Cognitive decline was detected by examination of the Montreal Cognitive Assessment-Indonesian version (MoCA-Ina) while other variables were obtained through interviews. The data were analyzed with Chi-square or Fisher exact tests. Age, education level, and age at hemodialysis initiation affect global cognitive function in CKD patients. In cognitive domain analysis, a significant relationship was found between age and duration of hemodialysis and attentional function, as well as the impact of age, sex, and age at hemodialysis initiation on executive/visuospatial function. Several demographic and hemodialysis characteristics are associated with cognitive decline in hemodialysis patients. Education and periodic cognitive screening are necessary to prevent and detect cognitive decline in these at-risk populations.

Knowledge Level and Beliefs of Mothers of Children Under 5 Years of Age About Childhood Vaccinations

Vaccination prevents infectious diseases and mother’s consent is key to increasing childhood vaccination rates. The aim of this study was to assess mothers' knowledge, and beliefs about childhood vaccinations, as well as the impact of these factors on their vaccination behaviors. A descriptive cross-sectional study of 320 mothers was conducted. The data were collected using a questionnaire form. Most of mothers (98.4%) have their children fully vaccinated through the Extended Immunization Program (EIP), 96.6% of cases support vaccines necessity. Vaccine hesitancy was 7.8%, vaccine refusal was 1.6%. The majority of mothers believe that the most common side effects of vaccines are fever (53.4%). Mothers were not adequately informed about EIP were 42.2%, and 57.5% of them had not received non-EIP vaccines, and 33.1% cited lack of knowledge as the reason. The majority of cases (73.7%) received information about EIP from a doctor. Parents' educational status, higher family income, and having more than three children significantly increased non-EIP vaccination rates but had no significant effect on EIP vaccination (p<0.05). Mothers still support EIP, but vaccine hesitancy is growing due to a lack of information. It is critical to assess mothers' knowledge and beliefs about vaccination, and social awareness is also required.
