Abstract

Blood transfusion, one of them, is a process of transferring blood components containing glucose, lactate, and potassium. During storage, blood cells undergo metabolic changes such as decreased blood pH, hemolysis, and increased potassium levels. One of the complications of transfusion that must be avoided is hyperkalemia due to the release of potassium. This study aimed to determine differences in stored blood potassium levels and PRC QC results during 11 days of storage. This was an analytic observational study with a cross sectional approach. A T-test was used to analyze the difference. In addition, PRC blood quality control (QC) was also carried out for stored blood according to standards. This study used 40 samples of fresh blood bags obtained from UTD PMI Yogyakarta City. The mean potassium level in fresh blood bags was 4.373 ± 0.417 mmol/L (3.70-5.50) and the average potassium level in blood bags stored for 6 days was 8.290 ± 0.275 mmol/L (7.80-8.90). There was a significant difference in potassium levels between fresh blood bags and blood bags stored for 6 days (p = 0.000). The overall QC PRC result is 50% which indicates the need for improvement in terms of the blood component separation process.

Abstract

Tuberculosis is still a health problem in the world. TB treatment is carried out in 2 phases, namely early and advanced. This study aims to determine changes in serum transaminase enzyme levels (SGOT and SGPT) in pulmonary TB patients before and after initial drug administration. This study was observational with a cohort study design study. Observations were conducted in tuberculosis patients who received initial ATD therapy for 2 months for SGOT and SGPT enzyme levels before and after treatment. The subject of the study was a new case of a pulmonary TB patient aged ?16 years. Subjects received initial therapy in the form of isoniazid, rifampicin, pyrazinamide, and ethambutol. Recruitment of subjects through successive sampling methods with informed consent. Using a spectrophotometer, SGOT and SGPT enzyme tests were performed on the median blood serum cubital vein. Data analysis using the Wilcoxon Test. The study involved 19 subjects (10 men and 9 women) aged 16-65 years. Before ATD, the mean SGOT was 22.84 IU/L, and SGPT was 21.37 IU/L. After ATD, SGOT increased to 58.63 IU/L (p = 0.023), and SGPT to 80.84 IU/L (p = 0.007). Of the 19 subjects, 8 experienced a significant increase in SGOT and 5 SGPT. Five cases showed an increase in SGPT in line with SGOT, and 3 cases showed an increase in SGOT without SGPT. One case saw an increase in SGOT and SGPT of more than 5 times the reference value. This study confirms an increase in transaminase enzymes during initial therapy with first-line ATD.

Abstract

This study investigates undergraduate EFL students’ experiences using QuillBot in academic writing contexts. Employing a qualitative descriptive approach, the researchers conducted in-depth interviews with six students who regularly integrated QuillBot into their writing practices. The findings revealed three major themes: strategic use of QuillBot throughout the writing process, challenges encountered during its use, and emerging pedagogical innovations related to AI-assisted writing. First, students used QuillBot strategically during planning, drafting, revising, and editing to paraphrase sentences, improve grammatical accuracy, enrich vocabulary, and enhance textual coherence. Second, despite its benefits, students experienced several challenges, including meaning distortion, overly formal expressions, overreliance on AI-generated suggestions, and reduced personal writing voice. Third, the findings highlighted pedagogical innovation in AI-assisted writing, as QuillBot contributed to increased writing confidence, improved linguistic accuracy, reduced writing anxiety, and greater writing efficiency. The study also emphasized the importance of AI literacy training, ethical guidelines, and lecturer support to promote critical, reflective, and responsible use of AI-assisted writing tools in EFL learning contexts.
