The role of gut microbiome in nutrition and its influenceon a healthy diet
type: item
description: The gut microbiome is a complex and dynamic ecosystem that plays a crucial role in human health, influencing various physiological processes including nutrition, metabolism, immune function, and mental well-being. This review explores the intricate relationship between the gut microbiome and nutrition, highlighting its impact on overall health. The composition and diversity of the gut microbiota are shaped by factors such as diet, age, genetics, and environmental conditions. Dietary patterns, particularly the consumption of probiotics, fermented foods, and specific macronutrients, can modulate the gut microbiome, affecting nutrient metabolism, vitamin synthesis, and the production of beneficial compounds like short-chain fatty acids. These microbial metabolites influence host health through mechanisms such as immune regulation and metabolic processes. The gut microbiome also plays a pivotal role in the gut-brain axis, a bidirectional communication network that influences mental health and cognitive function. Dysbiosis, an imbalance in the gut microbiota, has been linked to numerous health conditions, including obesity, metabolic disorders, and autoimmune diseases. While dietary interventions show promise in restoring microbial balance and improving health outcomes, challenges remain in gut microbiome research, including technical and methodological limitations, the need for standardization, and the complexity of human-microbiome interactions. As our understanding of the gut microbiome continues to evolve, it holds significant potential for advancing preventive medicine and improving overall human health. Future research should focus on overcoming current challenges to develop more personalized and effective microbiome-based therapies.

The Accuracy of The Malnutrition Screening Tool (MST) for Identifying Malnutrition Risk in Stroke Patient
type: item
description: Malnutrition in stroke patients is associated with poor clinical outcomes, making early nutritional assessment essential, as it is a modifiable risk factor. The Malnutrition Screening Tool (MST) offers a rapid and simple approach for nutritional screening; however, its application in stroke populations remains limited. This study aimed to evaluate the diagnostic accuracy of the MST compared with the Subjective Global Assessment (SGA) in stroke patients. A cross-sectional study was conducted involving 96 acute stroke patients at Atma Jaya Hospital, Jakarta, using retrospective medical records. The MST was employed for nutritional screening, while nutritional status was determined using the SGA. Bivariate analyses assessed associations between patient characteristics, MST scores, Body Mass Index (BMI), hemoglobin levels, and total lymphocyte count (TLC) with SGA classification. Logistic regression was used to determine the independent association between MST scores and nutritional status, and the Area Under the Curve (AUC) was calculated to evaluate MST validity. Results showed that 25% of patients were malnourished according to the SGA. Age, BMI, hemoglobin, TLC, and MST scores were significantly associated with nutritional status (p < 0.05). An MST score ≥2 increased the odds of malnutrition by 3.115 (p < 0.05). The MST demonstrated 75.0% sensitivity, 51.4% specificity, and an AUC of 0.674, indicating adequate diagnostic performance, though complementary assessment tools are recommended.

Review of Chemical Characteristics of Antioxidant Compounds and Biological Activities that have the Potential for Pharmaceuticals
type: item
description: Chemical characteristics of a compound to be an antioxidant compound are more reactive than the compounds making up cells and tissues as well as metabolic component compounds, to radical compounds in the mammalian metabolic system. A highly reactive compound is (1) has one or more unpaired electrons in the form of radical electrons or compounds that lose or excess electrons form ionic (2) have many paired electrons (3) the distance between groups or atoms that have radical electrons very close or distance between same ion in a compound or the distance between groups or atoms which have electron pairs very close in term chemical bond or in space or conformation (4) and compounds that contain a lot of oxygen atoms. Therefore, a group of potential compounds that have strong antioxidant activity is phenolic, especially polyphenols because they have a hydroxy group or another group that has many paired electrons, located in an aromatic ring very close in chemical bonds, or an electron pair between aromatic rings in a very close compound based on space. Furthermore, highly reactive compounds are potentially toxic because they react easily with chemical compounds making up cells and tissues, as well as metabolic component compounds; such as proteins, lipids as fats, carbohydrates, non-fat lipid compounds, and nucleic acids (DNA and RNA). Therefore, the excess of antioxidant compounds in the metabolic system is not good, if there is no free radical in the metabolic system or excessive radical compounds. Thus, the biological activity of antioxidant compounds that must be known if an antioxidant compound will be used in the pharmaceutical field is toxicity. Toxicity information that prospects to be continued as a pharmaceutical antioxidant product is minimally sourced from preclinical testing.

Guillain-Barre Syndrome: A Case Report
type: item
description: Guillain-Barre syndrome (GBS) is a complicated degenerative neurological disorder which can be acute or chronic in nature. It is an acquired condition which is characterized by progressive, symmetrical, proximal and distal tingling and weakness. Muscle stretch reflexes are decreased to absent and loss of sensation is common. Etiology remains unclear but pathophysiology includes demyelination of spinal nerve roots. Death is rare. Early diagnosis and prompt referral should occur in severe cases due to the incidence of potential ventilation failure and cardiovascular instability in some patients. The case of a 26-year-old male presenting to a physician is described. The importance of a correct diagnosis by the physician and the subsequent management is reviewed.

type: item
description: Cashew tree (Anacardium occidentale L), contains flavonoid compound which plays a role in the medical treatment of Diabetes Mellitus because this compound has activity as an ?-glucosidase inhibitor. Brotowali stem extract (Tinospora cordfolia) demonstrated ?-glucosidase inhibitory (AGIS) activity. This research aimed to measure 96% ethanolic extract AGIS activity of brotowali-cashew apple combination (BJM). The research was conducted by using ELISA reader instrument at 405 nm for AGIS activity test. The IC50 was calculated from each sample. The IC50 of brotowali stem and cashew apple was 34,61 ?g/ml and 109,32 ?g/ml. Then, the combination of brotowali and cashew apple extract was mixed with each concentration of 0,5%. From 1:0, 1:2, 1:1, 2:1, and 0:1 BJM comparison resulted in AGIS power percentage averages of 84.05%, 69.51%, 70.92%, 68.10%, 40.37%. The results of this research indicated that brotowali stem has the potential as AGIS, while cashew apple has not any potential towards AGIS and that extract combination does not give synergic effect. Therefore, the use of a combination of brotowali-cashew apple extract is not as effective as the use of brotowali single extracts to inhibit the ?-glucosidase enzyme

Antioxidants Activity of Self-Nanoemulsifying Drug Delivery System on Dayak Onions Extract (Eleutherine palmifolia) using DPPH (2,2 difenil-1- picrylhydrazyl) Method
type: item
description: Dayak onions (Eleutherine palmifolia L. Merr) is one plant that has been proven to have benefits as an antioxidant. The Dayak extract is formulated in the self nano emulsifying drug delivery system (SNEDDS) because the extract has low water solubility. The aims this study to develop the SNEDDS formulation system by testing its antioxidant activity. We determined whether there was an increase in antioxidant activity when formulated in the form of SNEDDS or not. The results were then compared with a solution of Dayak onions extract without using SNEDDS. The obtained formula was the optimal result that has been done before using the D-optimal mixture design method. The results of the components consisted of 50 mg of Dayak extract, 10 % caprylic triglyceride as oil, 1% tween 80, and 6,60 % transcutol as a combination surfactant and 12,40 % propylene glycol as co-surfactant. Antioxidant activity testing was carried out using the DPPH (1,1-Diphenyl-2-picrylhydrazyl) method. The antioxidant test using the DPPH method was done with two samples, namely the extract solution and Dayak onion extract SNEDDS. We elaborated the research by using UV-VIS spectrophotometer. Each sample was made into five concentrations, namely 30 ppm, 60 ppm, 90 ppm, 120 ppm, and 150 ppm, and carried out three times replications. The results showed that the IC50 value in the Dayak onion extract solution was 227,19 ppm (very low), while for the SNEDDS solution for the Dayak onion extract the IC50 value obtained was 38,97 ppm (very strong). The analysis was carried out next using an independent T-Test to obtain the results. There was no significant difference between the extract solution and the SNEDDS solution of Dayak onion extract.
