Abstract

Background: Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and one of the leading causes of cancer death worldwide. Chronic hepatitis B virus infection is the most common etiology of HCC. Programmed death ligand-1 (PD-L1) is a protein that is overexpressed on the surface of tumor cells, which can be detected in serum (sPD-L1). Elevated sPD-L1 concentrations in the plasma of cancer patients are associated with poor prognosis in HCC patients, as indicated by increased AFP levels. There have been no previous studies examining the correlation of sPD-L1 levels with AFP in HCC patients. The aim of the study was to determine the correlation of sPD-L1 and AFP as predictors of prognosis in HCC patients. Methods: The research is an observational study with a cross-sectional design to see the correlation of sPD-L 1 with serum alpha-fetoprotein levels in HCC patients at Dr. Mohammad Hoesin General Hospital Palembang starts from April to July 2023. Measurement of sPD-L1 levels and serum AFP levels is carried out using ELISA examination. Results: Of the 28 subjects studied, HCC patients were more commonly found in men (89.29%) aged 18-60 years (75%). sPD-L1 and AFP values were found to be increased in the advanced stages of HCC. The sPD-L1 value is directly proportional to the serum AFP value. Conclusion: There is a strong positive correlation between sPD-L1 levels and serum AFP levels caused by hepatitis B in HCC patients, so the higher the sPD-L1, the higher the serum AFP levels.

Abstract

Background: Gastrointestinal symptoms are common among patients with chronic kidney disease, reported in up to 70%–80% of patients with end-stage kidney disease. Several factors are involved in the pathogenesis, including the accumulation of uremic toxins and intestinal flora changes. Pseudomembranous colitis is a manifestation of severe colonic disease that is usually associated with Clostridium difficile infection but can be caused by a number of different etiologies. Pseudomembranous colitis occurs when changes in the fecal flora allow Clostridium difficile overgrowth. Gut dysbiosis, an alteration of the composition and function of gut microorganisms, is commonly seen in patients with chronic kidney disease. Case presentation: This scientific report presents a case study of a 31-year-old woman diagnosed with pseudomembranous colitis and end-stage chronic kidney disease on hemodialysis. The colonoscopy showed yellow-white nodules that formed pseudomembranes, which were scattered between the edematous mucosa. The patient had been treated with metronidazole for 4 days, but there were side effects. The antibiotic was switched to meropenem for 6 days based on feces culture. The evaluation of colonoscopy result was normal. Conclusion: Pseudomembranous colitis is an inflammatory bowel condition most commonly caused by Clostridium difficile infection. The presence of pseudomembranous visualization in colonoscopy can significantly establish the diagnosis.

Abstract

Tofu liquid waste, which has high BOD and COD values, can contaminate waters if it is directly disposed of without prior treatment. Therefore, waste treatment is necessary before being released into water. One method for treating this waste is by using a cellulose acetate membrane. In this research, a cellulose acetate membrane was synthesized from sugarcane bagasse fibers using the phase inversion method. The membrane was added 6% MSG as an additive to improve its performance. The membrane was applied to treat tofu waste with BOD and COD parameters. The membrane’s flux values obtained in this study were 33.56 L/(m².hour) for water and 26.85 L/(m².hour) for tofu liquid waste. SEM test result showed that the membrane with a 6% MSG additive had more pores and a denser surface compared to the membrane without the additive. The membrane was capable of decreasing BOD and COD values by 62.5% and 75.3% respectively in liquid tofu waste.
