Objective: This study aimed to determine the correlation between pentraxin-3 and procalcitonin levels with Sequential Organ Failure Assessment (SOFA) scores in septic patients. Design: This observational analysis with a cross-sectional method assessed the correlation between pentraxin-3 (PTX-3) and procalcitonin (PCT) levels and the SOFA scores of septic patients. Setting: We conducted this study in the Intensive Care Unit (ICU) of Dr. Wahidin Sudirohusodo Hospital and Medical Laboratory Center of Hasanuddin University from December 2023 to April 2024. Patients and participants: Thirty-two patients with clinical sepsis were admitted to the ICU of Dr. Wahidin Sudirohusodo Hospital. Intervention: Blood samples were collected on day 1 and day 2 of ICU care in septic patients to measure pentraxin-3 and procalcitonin levels. Measurements and results: The Wilcoxon test showed a significant difference in pentraxin-3 levels on ICU care's first and second days (p=0.036). Similarly, there was a significant difference in procalcitonin levels on the first and second days of ICU care. The Spearman correlation test found a significant correlation between procalcitonin and SOFA scores (p=0.008) with a correlation value r=0.462 on the first and second days. The resulting correlation value showed a positive correlation, which meant that the higher the procalcitonin level in septic patients, the higher the SOFA scores with moderate strength (correlation value 0.4-<0.6). The correlation of pentraxin- 3 with the Spearman test showed a positive correlation on the first day. In contrast, on the second day, there was no significant statistical value with the SOFA scores with a correlation value p=0.093 (p>0.05). Conclusion: Pentraxin-3 and procalcitonin levels correlate with SOFA scores in septic patients admitted to the ICU. [ABSTRACT FROM AUTHOR]

In-situ stirring batch reactor transesterification is a widely used method for the conversion of various biomass into biodiesel, particularly Nannochloropsis sp microalgae. Therefore, this study aims to investigate the effect of CaO/Hydrotalcite catalyst loading ratio and stirring rate on in situ stirring batch reactor transesterification of Nannochloropsis sp microalgae to produce biodiesel. In-situ transesterification was carried out using stirring with a four-blade paddle (50 w), while CaO/Hydrotalcite catalyst preparation was performed using incipient wetness impregnation. Nannochloropsis sp microalgae were then converted into biodiesel with varying loading ratio of catalyst (1:1, 3:1, and 5:1 %wt/wt) and stirring speed of agitation (50, 100,150, 200, and 250 rpm) for 4 hours (60oC). Subsequently, biodiesel obtained from the process was analyzed using gas chromatography (GC). The results showed that the surface area of CaO/Hydrotalcite was 45.756 m2/g. The conversion yields of Nannochloropsis sp microalgae to biodiesel with CaO/Hydrotalcite reached 38.36% with an agitation rate of 250 rpm. Based on the fatty acids analyzed using GC methods, the products predominantly contained olefine (61.49%) and gasoline (38.51%). [ABSTRACT FROM AUTHOR]
