Abstract

The increase in dyslipidemia cases every year requires the Clinical Chemistry laboratory to carry out quality control which is influenced by an assessment of accuracy and accuracy. These measurements were used with control materials. So far, in laboratories, there are still many commercial serum control materials used as controls that are used daily in triglyceride tests, and rarely use pooled sera. In fact, there are several advantages in using pooled sera as a control material. This type of analytic survey research with a comparative study method. The sampling technique used is purposive sampling. Data collection techniques were carried out using observation sheets. Data were processed computerized using univariate analysis and bivariate analysis using independent t-tests. The results showed that the average triglyceride examination value with Pooled Sera control material was 94.67 mg/dL with a Standard Deviation of 2.52, a coefficient value variance of 2.66%. While the results of triglyceride examination with Commercial Serum control material were 79.13 mg/dL with a Standard Deviation of 3.57, the coefficient of variance was 4.51%. It was concluded that there is a significant difference between triglyceride examination using Pooled Sera and Commercial Serum. It is recommended that there be developments in medical laboratory technology in hospitals, making this research a reference in educational institutions, and further research on other parameters between Pooled Sera ingredients and other Serum.

Abstract

Escherichia coli (E.coli) is a group of gram-negative bacteria that are part of the normal flora in the body. Under certain conditions, these bacteria can be pathogenic by producing enterotoxins that can cause serious infections such as diarrhea. Establishing the diagnosis of infection due to E.coli bacteria, namely through laboratory tests by identifying the bacteria through the bacterial staining method. So far, the most widely used bacterial dyes are synthetic dyes such as safranin. Safranin is a dye in Gram stain which can be carcinogenic and in the long run has a negative impact on health. To overcome this problem, it is necessary to innovate natural dyes that can be used as alternative dyes. Leaves of henna nails (Lawsonia inermis L.) is one of the natural ingredients which has an orange-orange lawsone pigment that is able to color the cell walls of gram-negative bacteria such as E.coli. The purpose of this study was to determine the ability of henna leaf extract (Lawsonia inermis L.) as an alternative to safranin staining. This research is a laboratory experiment. The experimental group was stained with henna leaf extract, using ethanol solvent concentrations of 25 mg/ml, 50 mg/ml, 75 mg/ml and 100 mg/ml. The control group used safranin dye. All research groups were carried out 3 repetitions. The parameters used were the clarity of the visual field, the shape of the bacteria, the cleanliness of the preparation and the color of the bacteria compared to the safranin control. The results showed that henna leaf extract was effective enough to be used as a coloring agent to replace safranin because it can color E.coli bacteria well.

Abstract

Background: The literature surrounding prehabilitation for patients undergoing orthopedic surgery has evolved significantly over recent years, highlighting its potential to enhance surgical outcomes through a multifaceted approach. Literature Review: Following this, (L. Waterland et al., 2021) conducted a systematic review and meta-analysis that highlighted the immediate postoperative benefits of prehabilitation, specifically regarding functional exercise capacity and hospital length of stay. The article by (H. Koh et al., 2021) further contributes to this discourse by focusing on the benefits of prehabilitation in mitigating sarcopenia among elderly patients. (H Koh et al., 2021) show that a structured presurgery prehabilitation program can improve surgical outcomes and reduce costs for aged patients. The integration of nutritional and psychosocial components into prehabilitation programs is advocated by (Paladini et al., 2023). Finally, (Ma et al., 2024) provide a bibliometric analysis that charts the evolution of prehabilitation research from 2005 to 2023. This review identifies emerging trends in the literature, particularly concerning malnutrition and frailty among older patients. Conclusion: In conclusion, the reviewed literature collectively underscores the growing recognition of prehabilitation as a vital component of surgical care, particularly for at-risk populations. It advocates for personalized, multimodal approaches that integrate physical, nutritional, and psychological interventions to enhance patient outcomes and optimize recovery processes in the context of orthopedic surgery.
