Abstract

Background: Hepatitis C Virus (HCV) is an RNA virus that causes hepatitis C disease. Hemodialysis patients are a group at high risk of becoming infected with the HCV. Based on prior research, the duration of hemodialysis has been identified as an independent risk factor for HCV. Risk factors for HCV transmission in hemodialysis patients can also include blood transfusions. Purpose: This research aimed to determine the relationship between the duration of dialysis and the history of blood transfusion with HCV seroprevalence in hemodialysis patients at Gadjah Mada University Academic Hospital. Method: This research utilized a cross-sectional research design. The research data were based on secondary data from the medical records of hemodialysis patients at Gadjah Mada University Academic Hospital. Result: The results were analyzed descriptively and statistically using the Chi-square test with significance (α = 0.05). Data obtained from this research showed that the HCV seroprevalence of hemodialysis patients at Gadjah Mada University Academic Hospital is 20.5%. The test results revealed a relationship between duration of dialysis with HCV seroprevalence in hemodialysis patients is a p-value = 0.021 (p-value < α), and a relationship between history of blood transfusion with HCV seroprevalence in hemodialysis patients is a p-value = 0.024 (p-value < α). Conclusion: The results of the Chi-square test showed a relationship between duration of dialysis and history of blood transfusion with HCV seroprevalence in hemodialysis patients at Gadjah Mada University Academic Hospital.

Abstract

Background: Two-thirds of primary liver tumors in children are malignant. Hepatoblastoma (HBL) accounts for 40-60 percent of pediatric liver tumors and is the most common malignant liver tumor. Hepatocellular Carcinoma (HCC) is the second most common malignancy in children, accounting for approximately 20% of cases. Both malignant liver tumors have similar clinical and imaging features, but different prognosis and treatment. Purpose: This report aims a case of liver cancer related to hepatitis B virus infection in a child. Case analysis: A 15-year-old girl presented with a two-month history of right upper quadrant pain along with abdominal distension, weight loss, back pain, anorexia, nausea, weakness and fatigue for 5 months prior to admission. Physical examination revealed a hard, firm mass with a bumpy surface in the right upper quadrant of the abdomen and splenomegaly. Laboratory test showed an increase in Lactate Dehydrogenase (LDH), Gamma-Glutamyl Transpeptidase (GGT), Alpha Feto Protein (AFP), quantitative Hepatitis B Virus (HBV) DNA, and HBsAg reactive. Abdominal Multi-Slice Computed Tomography (MSCT) revealed malignant solid mass with necrotic component inside, indistinct borders, irregular margins and kissing spleen. Result: The diagnosis of liver cancer in this patient suggested HCC associated with chronic hepatitis B infection. Conclusion: Routine follow-up of all children with chronic hepatitis B infection is crucial because of the risk of developing liver cancer in adolescence and adulthood.

Abstract

Background: Work fatigue among PT. PAL Indonesia workers occurs due to several factors, such as working under high temperatures and sunlight without the aid of temperature reducing equipment and the lack of easily accessible drinking water around the workplace, which can trigger dehydration in workers. Purpose: This study aims to analyze the strength of the relationship between drinking water consumption and dehydration on work fatigue in floating and digging dock workers at PT. PAL Indonesia. Method: This research is an observational study with a cross-sectional approach, involving a sample of 26 dock workers from the Harkan Division at PT. PAL Indonesia. Data collection was conducted through measuring work fatigue using a reaction timer, questionnaires, interviews, and observations. Result: The analysis between variables shows a strong relationship between dehydration and work fatigue of 0.606 and a very weak relationship between drinking water consumption and the incidence of work fatigue of 0.135. Conclusion: It is suggested that the company should regularly provide drinking water supplies for workers and place them in locations that are easily accessible. Apart from that, the company should encourage workers to consume more water instead of other drinks to protect them from possible diseases beyond work fatigue.

Abstract

Background: The surface roughness of orthodontic arch wires is an essential factor that affects the effectiveness of arch-guided tooth movement. Metal wires exposed to the oral cavity environment are susceptible to corrosion. The corrosion process cannot be stopped but can be inhibited using natural inhibitors that contain antioxidant compounds, such as tannins found in avocado seeds. Tannins in avocado seed extract can act as a corrosion inhibitor through two working mechanisms, a passive layer and an adsorption process. Purpose: The aim of this study was to examine the viability of avocado seed extract as a corrosion inhibitor on the surface characteristic of orthodontic wires. Method: This research is an experimental laboratory research.  A total of 48 orthodontic wires (stainless steel, nickel titanium, and Titanium-Molybdenum Alloy (TMA)) were prepared and divided into control and treatment groups. The treatment groups were immersed in avocado seed extract at concentration of 1.5 g/L (T-1), 2 g//L (T-2) and 2.5 g/L (T-3) for 7 days with twice daily immersion of 1 minute each. A TR 220 surface roughness tester (ΔRa) was used to evaluate surface characteristic. The data was analyzed using the one-way ANOVA test followed by post hoc LSD test with a significance value of p-value < 0.05. Result: The average surface roughness increased in all control groups except for stainless steel wire which did not show a significant difference with p-value = 0.716. Furthermore, the difference test between groups on each wire showed different results. Conclusion: Avocado seed extract is effective as a corrosion inhibitor for orthodontic wires.
