Abstract

Indonesia is one of the countries with the highest number of cases of hypertension in the world; the predominant patient is the elderly. In some patients with hypertension, increased blood pressure causes impaired salt and creatinine excretion, resulting in poor kidney function. A chronic disease management program is a health care system with a proactive-integrative approach to prevent further complications. The research objective is to analyze serum creatinine levels, blood pressure, and hypertension grade and determine the relationship between serum creatinine and blood pressure in chronic disease management program participants. The study subjects, 73 participants with hypertension, were obtained by purposive sampling. Patient data and hypertension grade were obtained from medical records; an auto chemistry analyzer analyzed serum creatinine. Data were analyzed using the Pearson correlation test using SPSS. Participants with hypertension fall into the elderly age (60-69 years), totalling 31 (42%); pre-elderly age (45–59 years) includes 28 (38%); and high-risk elderly age (>70 years) includes 14 (19%). Most of the participants (40 participants) fell into hypertension stage II, followed by hypertension stage I (25 participants), and only 8 participants fell into the elevated category. The mean serum creatinine of participants with Elevated blood pressure criteria was 0.89±0.178, Hypertension grade I 0.91±0.322, and hypertension grade II 0.99±0.269, illustrating a trend of increasing serum creatinine levels due to higher blood pressure criteria. Pearson correlation test shows a significant correlation between both systolic blood pressure with serum creatinine levels (p<0.05, r=0.2) and diastolic blood pressure with serum creatinine levels (p=0.007, r=0.342). There was a trend of increasing serum creatinine levels corresponding to the hypertension grade in participants. Blood pressure was significantly correlated with serum creatinine, clearly confirming that an increase in blood pressure may followed by an increase in serum creatinine.

Abstract

Intestinal helminth infections are the most widespread of the world's neglected tropical diseases, primarily affecting morbidity in school-age children. Early and accurate intestinal helminth detection is important to determine an effective treatment for reducing morbidity. This research objective is to compare intestinal worm infections in elementary school children in swampy wetland areas using the Kato-Katz method and Flotation techniques. Two hundred ninety-six elementary school children in Danau Panggang Swamp-wetland, 6-13 years old, were examined for intestinal helminth eggs in no-preservative feces using microscopies Kato Katz and Floatation. The result of Kato Katz was a total egg counting per gram feces of Ascaris lumbricoides 23-92/gr feces Trichuris trichiura 23-207/gr feces and Fasciolopsis buski 23-69/gr feces, while the results of Floatation only Ascaris lumbricoides 10-50/gr feces Trichuris trichiura 20-90/gr feces. The percentage of intestinal helminth infection by Kato Katz was 31,76% (94 samples), which is higher than by the Floatation was 25,34% (75 samples). The Wilcoxon statistical test obtained a significance value of 0.001, which shows p<α (α=0.05); there is a significant difference between the results of the quantitative examination of intestinal worm eggs between the Kato Katz and Floatation technique. It is recommended that Kato Katz's performance testing be continued compared to PCR methods and a wider sample area.

Abstract

The prevalence of diabetes mellitus is rising globally. Oxidative stress, which can result from hyperglycemia in diabetes, might have negative consequences. An antioxidant is needed to prevent hyperglycemia. Cathechin isolates are derived from gambir, which has many antioxidants. This study examines catechin isolates from gambir (Uncaria gambir Roxb.) effect on glucose homeostasis in rats induced by alloxan. For this experiment, 35 male rats were employed. Male rats were given alloxan (150 mg/BW, IP), and after 72 hours, blood glucose levels were assessed. If blood glucose levels exceeded 200 mg/dl, three oral catechin isolates were administered (T1=10 mg/kg/day, T2=20 mg/kg/day, and T3=40 mg/kg/day). Following blood collection on the experiment's last day, fasting blood glucose, glucagon and insulin levels were measured. Catechin isolates decreased blood glucose levels in all treatment groups compared to the positive control group (T1 = 150.750 ± 14.359 mg/dl; T2 = 159.750 ± 15.434 mg/dl, and T3 = 153.375 ± 20.207 mg/dl vs 385 ± 60.989 mg/dl) significantly (p value-0.05). A decrease in glucagon serum level was also observed in the treatment group vs positive control (T1: 193.855 ± 36.009 pg/ml, T2 = 286.689 ± 20.313 pg/ml, and T3 = 319.462 ± 30.060 pg/ml vs  529.825 ± 74.279 pg/ml), significantly. Catechine isolates in the T3 group showed an increase in insulin serum level compared to the positive control group significantly (T3 = 216.640 ± 38.230 µIU/ml vs 69.833 ± 3.071 µIU/ml). In conclusion, catechin isolates from gambir decreased blood glucose levels by reducing glucagon and increasing insulin serum levels.

Abstract

Water is the main need of living things in the world. Water determines the sustainability of living things. Humans, animals, and plants depend on water for their survival. Therefore, water should always meet the standards that have been set. Wastewater from the home-based sasirangan industry has distinctive characteristics in the form of the color of wastewater that has not been managed properly. The purpose of this study was to determine the ability of alum to reduce the color of home-based sasirangan industry wastewater. The type of research is a true experiment, with the population being all home-based sasirangan industry wastewater in Atun Sasirangan Cempaka. The sample is part of the wastewater. The wastewater was put into 25 containers for 5 treatments of alum addition with concentrations of 40%, 80%, 160%, 240%, and 320%.  Each treatment was repeated 5 times. The results showed that the average value of wastewater color after treatment ranged from 140.5 to 179.2 Pt-Co. The lowest average value was in the treatment of adding alum with a concentration of 160%. It is concluded that alum is able to reduce the color of home-based sasirangan industry wastewater. It is recommended that the handling of wastewater color problems in the sasirangan fabric home industry use alum as a coagulant in the treatment method.

Abstract

Malaria due to Plasmodium falciparum causes a high mortality rate, and vaccination is a valuable approach to control it. One malaria vaccine candidate is Plasmodium falciparum erythrocyte membrane protein-1 (PfEMP1), specifically Duffy binding-like 2β (DBL2β) domain (DBL2β-PfEMP1), which has a vital role in severe malaria pathogenesis. The DBL2β-PfEMP1 recombinant protein is immunogenic. This study aimed to investigate the immune response of DBL2β-PfEMP1 protein by analyzing the differential leukocyte count. Twenty-three rats were randomly divided into control and five treatment groups. Rats were injected on days 0, 21, and 42 with a physiological solution of 0.9% NaCl, adjuvant, DBL2β-PfEMP1 protein, and each mixture of DBL2β-PfEMP1 protein with doses of 150, 300, and 450 µg/200gBW and adjuvant. Blood was collected on day 56 and prepared for differential leukocyte count examination with a visual microscopic examination by two expert observers. The results showed that DBL2β-PfEMP1 recombinant protein and adjuvant increased the eosinophils and neutrophils but decreased monocytes and lymphocytes and did not affect the basophils. Statistical analysis showed significant differences between groups for eosinophils (between control and DBL groups; Adj and DBL groups; DBL and other groups except DBL150+adj) and monocytes (between control and all doşe groups with adjuvant; DBL and all doşe groups with aduvant), but not for basophils, neutrophils, and lymphocytes. In conclusion, the serial injection of DBL2β-PfEMP1 recombinant protein showed different responses in each leukocyte cell type. Further analysis by time-series differential leukocyte count examination will be essential to determine the responses of each type of leukocyte to support the research on malaria vaccine development.

Abstract

Exposure to lead in the workplace is common, with most employers and workers unaware of its adverse health effects. This study examines the relationship between blood lead levels in battery factory workers and health examination results such as Hematology profile (Hemoglobin level, Leukocyte count, Hematocrit Level, Platelet count, Erythrocyte Count, MCV, MCH, and MCHC), malondialdehyde (MDA), ferritin, and hs-CRP. The samples of this study were 25 blood samples of battery factory employees in Jakarta who were older than 40 years and had worked for more than 1 year. Workers' blood samples were collected using vacuum tubes and placed in ice boxes to be sent to PT Petrolab Service Laboratory for blood lead level examination, Citama Hospital Laboratory Unit for blood profile examination, ferritin level, and hs-CRP value, and Prodia Jakarta Clinical Laboratory for MDA level examination. Bivariate analysis examined the relationship between lead levels, blood profile, ferritin levels, MDA levels, and hs-CRP values. Using the entered formula, multivariate analysis was used to test the relationship between lead levels and blood profile, ferritin levels, MDA levels, and hs-CRP values. The significance level used to test the significance of the relationship was <0.05. The bivariate test results showed there was a correlation between blood lead levels and hs-CRP levels (P=0.000), MDA levels (P=0.000), ferritin levels (P=0.000), Hb levels (P=0.000), hematocrit levels (P=0.006), MCV value (P=0.000), and MCH value (P=0.004). In contrast, Multivariate analysis showed lead levels significantly correlated with MDA level (P=0.014), ferritin level (P=0.005), and MCV value (P=0.013). Blood lead levels should be controlled to reduce the risk of oxidative stress and its impact on health, and it is hoped that workers in contact with lead will place more emphasis on occupational safety and health.

Abstract

Ultraviolet B (UVB) exposure is the main cause of skin damage leading to photoaging, increasing Reactive Oxygen Species (ROS) and triggering the production of Matrix metalloproteinase-1 (MMP-1) enzymes that play an important role in photoaging, describing clinical signs including wrinkles, thickening, dryness and pigmentation. Astaxanthin can inhibit ageing and reduce wrinkles, has strong antioxidant potential that can neutralize ROS, and suppress MMP-1 activity. The purpose of this study was to determine the effect of astaxanthin cream on the levels of MMP-1 and Superoxide Dismutase (SOD) enzyme production in mouse skin tissue exposed to short-term UVB light experimental research with a post-test-only control group design. The experimental animals used were 28 Wistar rats divided into 4 groups, namely group K1 (healthy), group KN exposed to short-term UVB and given base cream, group P1 exposed to short-term UVB rays and given 0.05% astaxanthin cream, and group P2 exposed to short-term UVB rays and given 0.1% astaxanthin cream. The treatment was carried out for 5 days, and on the 6th day, the levels of MMP-1 enzyme production in skin tissue and SOD were examined using the immunohistochemical method. Based on One-way ANOVA, there was a significant difference in the average levels of MMP-1 enzyme production in the skin tissue of all groups (p = 0.000). The highest MMP-1 production was found in the KN group, while in the P2 group, the levels were lower and not significantly different from the healthy group (K1). Significant differences in SOD expression were also observed among all groups (p = 0.000) using the Kruskal-Wallis test. The highest SOD expression was found in group P2 and was significantly different from groups P1 and KN. Topical astaxanthin cream administration affected MMP-1 enzyme production in skin tissue and SOD expression in Wistar rats exposed to short-term UVB radiation. Astaxanthin-based cream formulation has the potential to be developed as a topical agent to prevent skin damage caused by sun exposure, and these findings require further validation through studies on human skin models or early clinical trials.

Abstract

Kombucha is a fermented beverage known for its various health benefits, including antibacterial activity. This study aims to evaluate the antibacterial potential of mango ginger (Curcuma mangga)-based kombucha against Escherichia coli and Salmonella typhi, as well as to analyze the effect of fermentation duration on the physicochemical properties of kombucha. Fermentation was conducted for 5, 7, 10, and 14 days, with total acidity, pH, and antibacterial activity measurements using the well diffusion method. The results showed total acidity increased as fermentation progressed, while pH decreased. Antibacterial tests demonstrated that mango ginger kombucha exhibited inhibitory activity against Escherichia coli and Salmonella typhi, with the largest inhibition zones observed on day 10 of fermentation (8.2 mm for Escherichia coli and 9.2 mm for Salmonella typhi). Although its inhibitory effect was moderate compared to the positive control (ciprofloxacin), these findings suggest the potential of mango ginger kombucha as a functional beverage with antibacterial properties. Further research is needed to identify the active compounds responsible for its antimicrobial activity and to optimize the fermentation process to enhance its effectiveness.

Abstract

The increasing prevalence of obesity and its associated complications necessitates the exploration of functional foods as therapeutic interventions. This study aimed to analyze the effects of fermented buffalo milk (dadih) fortified with red dragon fruit (Hylocereus polyrhizus) and selenium on adiponectin and Tumor Necrosis Factor-Alpha (TNF-α) levels in obese rats. This experimental study employed a pretest-posttest control group design involving 20 Wistar rats divided into four groups: K1 (healthy control), K2 (obese control), P1, and P2 (obese intervention). K2, P1, and P2 were in obesity conditions induced by a high-fat-fructose diet (HFFD) for 28 days, and K1 was a healthy control group. Furthermore, dadih only and dadih fortified with red dragon fruit and selenium at 1.8 g/200 g body weight/day were administered to P1 and P2 groups, respectively. Treatment using dadih fortified with red dragon fruit and selenium significantly reduced weight gain (p=0.000) compared to K2 and P1. In addition, the P2 group showed increased adiponectin levels and decreased TNF-α levels (p=0.000) compared to the K2 and P1 groups. A strong negative correlation was found between adiponectin levels and TNF-alpha and body weight, while TNF-alpha and body weight showed a strong positive correlation. To conclude, fortifying dadih with red dragon fruit and selenium is more effective in improving the metabolic condition of obese rats compared to non-fortified dadih. This fortification significantly enhances adiponectin levels and reduces TNF-alpha levels. These findings suggest that functional food fortification could be a promising approach for managing obesity-related inflammation and metabolic disorders in humans, highlighting the potential application of dadih in dietary interventions.

Abstract

Green glutinous rice tape is a fermented food made from glutinous rice, katuk leaves (Sauropus androgynus), and yeast, originating from Tembilahan, Riau Province. This product can serve as a source of lactic acid bacteria (LAB) capable of producing antimicrobial compounds to inhibit pathogenic microorganisms, including Aspergillus flavus, a well-known spoilage fungus in food products. However, to date, no reports have explored the ability of LAB from green glutinous rice tape to inhibit the growth of Aspergillus flavus. This study aimed to isolate LAB from green glutinous rice tape, conduct macroscopic, microscopic, and biochemical characterizations, and evaluate the antifungal activity of the LAB isolates against Aspergillus flavus using the good diffusion method. The isolation process yielded four LAB isolates from Tembilahan green tape (TKHT-2, TKHT-3, TKHT-5, and TKHT-7), which were identified as members of the genus Lactobacillus sp., with antifungal activities of 25.50 ± 5.78 mm, 24.33 ± 0.62 mm, 22.16 ± 6.56 mm, and 18.66 ± 4.28 mm, respectively. The corresponding cell-free supernatants (CFS) from these isolates (TKHT-S2, TKHT-S3, TKHT-S5, and TKHT-S7) also demonstrated antifungal activity with inhibition zones of 19.83 ± 3.47 mm, 19.83 ± 4.24 mm, and 14.50 ± 3.26 mm, respectively. LAB cells and their cell-free supernatants partially inhibited Aspergillus flavus, indicating a fungistatic effect. These findings suggest the potential application of LAB from green glutinous rice tape as a natural preservative or antifungal agent in food products.
