Background: The effect of HBO2 alone on Sirt-1 and Syndecan-1 is unknown, even though both molecules are involved in preventing endothelial dysfunction. This study aims to determine the effect of HBO2 on Sirt-1 and Syndecan-1 as therapeutic targets for endothelial dysfunction. Method: This study employed a true experimental post-test design. Twenty male Sprague Dawley rats aged 12-14 weeks were divided into two groups. Diving was carried out in an animal hyperbaric chamber with a dose of 2.4 ATA for 60 minutes. All data were collected 18 hours after diving. Results: Our study revealed that the administration of HBO caused an increase in serum MDA and endothelial NF-kB levels (p = 0.007; p = 0.001, respectively) without an increase in any inflammatory markers, specifically IL-1 and VCAM-1 levels (p = 0.707; p = 0.168, respectively). HBO2 decreased Syndecan-1, a marker of endothelial injury (p = 0.026), but did not affect endothelial eNOS and Sirt-1. Conclusion: HBO2 did not cause endothelial injury and inflammation, but the dose used was not enough to increase Sirt-1 levels. Additional research is needed to determine a hormesis dose that can increase Sirt-1 levels.

Background: The mechanism involved in HBO2 preconditioning in preventing inflammation in diving is still unclear. Syndecan-1, which is an important part of glycocalyx, has never been studied for its involvement in HBO2 preconditioning to prevent inflammation in decompression diving. This study aims to determine how HBO2 preconditioning impacts inflammation through Syndecan-1, MDA, and IL-1a markers. Method: This study is a true experimental post-test design. Forty male 12- to 14-year-old Sprague Dawley rats were divided into four groups. HBO2 and decompression diving were carried out in an animal hyperbaric chamber. All data were collected 12 and 24 hours after the decompression diving. Result: The incidence of decompression sickness was less frequent in the HBO2 preconditioning treatment group as opposed to the control group (4 vs 9) but did not reach a significant level (p \> 0.05). All parameters showed no difference between the control and treatment groups 12 hours after the dive (p \> 0.05). Twenty-four hours after diving, the treatment group demonstrated substantially elevated IL-1a levels in comparison to the control group (p = 0.030), and the increase of IL-1a in the treatment group is significant (p = 0.001). Although MDA levels did not reach significant, the treatment group{\textquoteright}s increase in MDA levels 24 hours after diving was greater than that of the control group. Meanwhile, The treatment group had a smaller reduction in Syndecan-1 levels in comparison to the control group following diving 24 hours later. Conclusion: HBO2 preconditioning prolongs the inflammation, as evidenced by increased levels of MDA, Syndecan-1, and IL-1a, even though it can prevent decompression sickness. Further research is needed to find the right time and dose of HBO2 preconditioning to shorten the inflammation time.

Background and Objective: A specific examination is required to distinguish between DVI and viral, bacterial, and parasitic illnesses because their clinical manifestations are nearly identical. Leukopenia and lymphocytosis are examples of non-specific tests that might be used to get a diagnosis. Non-structural protein 1 (NS1) antigen, anti-DENV antibody, or DENV-specific nucleic acid detection are more specific assays. Methods: Virus isolation or molecular analysis of the detection of DENV nucleic acid ribonucleic acid (RNA) using RT-PCR was used to make the conclusive diagnosis of DVI. The sensitivity of the DENV RT-PCR method ranges from 28.8 to 99\%. NS1 antigen is used as an initial diagnostic option in primary health care because it has a high specificity value (100\%). Researchers want to analyze the positivity in non-DVI samples that have been confirmed by real-time RT-PCR examination with semi-quantitative NS1 antigen examination. Patient population aged 1-65 years with acute fever \<5 days. A total of 130 samples of non-DVI confirmed patients by RT-PCR were examined for NS1Antigen ELISA. Results: With a proportion of 3.08\% of the total sample, the results showed that 4 NS1Antigen ELISA samples were positive. A negative DENV RT-PCR result could indicate either a true negative or a false negative. Conclusion: The type of PCR technology, the primer used, the existence or absence of a DENV mutation, the DENV serotype, and the presence of mismatched nucleotides can all affect variations in DENV PCR sensitivity.
