The average CNR improvement was 18.4% on all SAFIRE strength values compared. This increase is affected by a linear decrease of the noise value from one SAFIRE strength value to another. Image contrast improvement also affects the pathological assessment of SNH due to the increased density differences in the hypodense lesion compared to the surrounding tissues. <strong>Conclusion:</strong> The use of the SAFIRE strength variation significantly affects image contrast values and pathological assessment in the SNH brain MSCT examination.</em></p> I Putu Eka Juliantara Angel Lingkan Martoyo Made Sayang Pratista Copyright (c) 2024 Journal of Vocational Health Studies https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-05 2024-03-05 7 3 142 150 10.20473/jvhs.V7.I3.2024.142-150 BACTERIAL PROFILE AND ANTIBIOTIC SUSCEPTIBILITY TEST AMONG DIABETES MELLITUS PATIENTS WITH GANGRENE IN SURABAYA https://e-journal.unair.ac.id/JVHS/article/view/41535 <p style="text-align: justify;"><em><strong>Background:</strong> Gangrene is a severe complication of damaged tissue that can occur in people with Diabetes Mellitus (DM), putting them at risk for bacterial infection.

To expedite the healing of chronic wounds, numerous studies have begun to utilize gels, including hydrogels or sol-gels, which incorporate a combination of antioxidant properties. Curcuma xanthorrhiza is known to contain polyphenolic compounds, which include flavonoids acting as an antioxidant. <strong>Purpose: </strong>Examine the potential of C. xanthorrhiza extract (CXE) gel as a candidate for wound-healing by measuring its antioxidant activity. <strong>Method: </strong>Three CXE gel formulas were prepared from different concentrations of CMC-Na (3, 4, and 5%). Each formula consisted of 5% CXE, 15% propylene Glycol, 10% Glycerin, 0.25% Methylparaben, and distilled water. The quality of the CXE gel was tested through homogeneity, spreadability, pH, and viscosity tests. The antioxidant activity was measured by 2,2-Diphenyl-1-picrylhydrazil (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)-reducing activity assay in a gel formula that was close the standards. The measurement results were then used in the calculation of antioxidant activity to determine the IC</em>50 <em>value. <strong>Result: </strong>Formulas 1, 2, and 3 meet the requirements by yielding a homogeneous gel with a spreadability of 5.37 – 5.93 cm, a pH level of 5.87 – 6.10, and a viscosity of 8.800 – 9296.67 cps. The highest DPPH and ABTS percentages were 34.04% and 5.28%, respectively. The IC</em>50 <em>values of CXE gel in DPPH and ABTS were 1973.38 μg/mL and 700.65 μg/mL, respectively. <strong>Conclusion: </strong>The CXE 1, 2, and 3 gel formula meets the requirements and has the potential to be used as a wound healing therapy through its antioxidant properties.</em></p> Reghita Claudia Malau Sri Wahyuni Nasution Ali Napiah Nasution Wahyu Widowati Faradhina Salfa Nindya Hanna Sari Widya Kusuma Copyright (c) 2024 Journal of Vocational Health Studies https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-05 2024-03-05 7 3 166 174 10.20473/jvhs.V7.I3.2024.166-174 ELEVATED BLOOD LEAD LEVELS IN WOMEN OF REPRODUCTIVE AGE DUE TO LEADS EXPOSURE FROM CONTAMINATED WATER https://e-journal.unair.ac.id/JVHS/article/view/42452 <p style="text-align: justify;"><em><strong>Background:</strong> Water quality can decrease due to population growth, domestic waste handling, climate, and human activities. Most of the people in Cimahi use well water for drinking and eating. However, using well water with high lead levels for consumption can adversely affect on the lead levels in the women’s blood of childbearing age. <strong>Purpose:</strong> This study investigates the relationship between lead levels in well water and the corresponding levels found in women’s blood in the Leuwigajah area of Cimahi. <strong>Method:</strong> Research samples were collected from both well water and the women’s blood of childbearing age (15 - 49 years) who consume well water for drinking and cooking. Subsequently, sample preparation was conducted, and the samples were analyzed using an atomic absorption spectrophotometer. The Spearman correlation test was employed to analyze the data and establish any potential correlations. <strong>Result:</strong> The lead content in water ranged from 0.055 ppm to 0.089 ppm, exceeding the requirements for lead in clean water. Meanwhile, lead levels in the blood ranged from 1.5 ug/dL to 78.2 ug/dL, with 6.7% falling within the normal category, 40% in the tolerable category, 30% in the excess category, and 23.3% in the high category. The statistical results show a significant relationship between lead levels in well water and the blood, with a correlation value of 37.9%. The correlation value indicates a weak positive relationship. <strong>Conclusion:</strong> There is a relationship between lead levels in well water and women’s blood.</em></p> Perdina Nursidika Dedeh Kurnia Ganthina Sugihartina Copyright (c) 2024 Journal of Vocational Health Studies https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-05 2024-03-05 7 3 175 180 10.20473/jvhs.V7.I3.2024.175-180 RELATIONSHIP BETWEEN WORK DURATION, LENGTH OF WORK, AND SLEEP DURATION WITH WORK FATIGUE AMONG ONLINE TAXI BIKE DRIVERS IN GREATER JAKARTA https://e-journal.unair.ac.id/JVHS/article/view/42938 <p style="text-align: justify;"><em><strong>Background: </strong>Online taxi bike drivers were part of the road users vulnerable to accidents due to a demand that required online taxi bike drivers to work on the highway.

The prevalence of Enterococcus spp. among different samples was 4.83%. The number of highly sensitive strains ranged from 66.66% to 77.77% for antibiotics, namely gentamycin, ampicillin, amoxicillin, and meropenem. Moderately high sensitivity to levofloxacin (29.62%) and low sensitivity to doxycycline (14.81%) were also analyzed. <strong>Conclusion:</strong> The study recommends that antibiotics should be used after proper laboratory procedures are undertake, and it should be selected based on antimicrobial susceptibility tests.</em></p> Turin Afroz Copyright (c) 2024 Journal of Vocational Health Studies https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-05 2024-03-05 7 3 200 205 10.20473/jvhs.V7.I3.2024.200-205 Front Matter Vol. 7 No. 3 2024 https://e-journal.unair.ac.id/JVHS/article/view/55022 <p>Front Matter Vol. 7 No. 3 2024</p> JVHS Copyright (c) 2024 Journal of Vocational Health Studies https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-05 2024-03-05 7 3 THE ROLE OF ARTIFICIAL INTELLIGENCE (AI) ON MRI BRAIN EXAMINATION WITH CLINICAL ISCHEMIC STROKE https://e-journal.unair.ac.id/JVHS/article/view/40832 <p style="text-align: justify;"><em><strong>Background:</strong> Application of Artificial Intelligence (AI) in radiology is named automatic image interpretation of neuroimaging stroke. It takes a short time to minimize the patient's brain damage. <strong>Purpose:</strong> Determine the role of AI in ischemic brain stroke MRI examination and find out the advantages and disadvantages of applying AI to ischemic brain stroke MRI examination. <strong>Review</strong><strong>:</strong> It was a descriptive and qualitative study with a literature review approach. The selection of articles used the ScienceDirect, Scopus, ProQuest, PubMed, and Publish or Perish databases. The inclusion criteria included full articles, with the topic of AI on ischemic brain stroke MRI examinations published in the 2017 – 2022 range, articles published by English-language international journals with a classification of Q1 – Q3, and having DOI. Seven relevant pieces of article were obtained, then descriptive analysis was carried out by comparing and presenting the articles descriptively in tabular form. <strong>Result:</strong> The role of AI in MRI brain examination with clinical ischemic stroke, namely its role in automatic lesion segmentation, Time Since Stroke (TSS) classification, and infarct volume prediction. The advantages of AI included short image processing times and accurate results. The disadvantages of AI tended to decrease performance in small lesions, a large number of patients, limited data, and false positive results. The value of the Dice Score Coefficient (DSC) (0.53 – 0.86) was already high even though it had not reached 1 because it depended on the strength of the data used. <strong>Conclusion:</strong> The role of AI in MRI imaging of ischemic brain stroke helps in the diagnosis and prognosis of ischemic stroke patients. AI in stroke neuroimaging has advantages in time effectiveness and disadvantages in data limitations.</em></p> Oktaviani Aulia WMS Emi Murniati Agustina Dwi Prastanti Copyright (c) 2024 Journal of Vocational Health Studies https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-05 2024-03-05 7 3 206 217 10.20473/jvhs.V7.I3.2024.206-217 Back Matter Vol. 7 No. 3 2024 https://e-journal.unair.ac.id/JVHS/article/view/55023 <p>Back Matter Vol. 7 No. 3 2024</p> JVHS Copyright (c) 2024 Journal of Vocational Health Studies https://creativecommons.org/licenses/by-nc-sa/4.0 2024-03-05 2024-03-05 7 3
