Nutritional targeting modification of silkworm pupae oil catalyzed by a smart hydrogel immobilized lipase.

To prepare a nutritional supplement using silkworm pupae oil (SPO) as a feedstock, a microfluidic reactor with a smart hydrogel immobilized lipase was first constructed to reduce the relative content of palmitic acid at sn-1,3 and improve the nutritional function. The effects of flow rate, reaction temperature, and substrate molar ratio were investigated. In vitro digestion and pH-stat models were employed to analyze the digestion feature after the modification of SPO, while HPLC-ELSD, zeta potential, DSC, and TGA were used to evaluate the nutritional function. The relative content of "OOO" and "OPO" type triglycerides was increased by 49.48% and 107.67%, and that of palmitic acid at sn-1,3 was decreased by 49.61% in 10 s. After the verification of the in vitro digestion model, the fatty acid release rate of the modified SPO was significantly improved by 22.07%, indicating the nutritional function improvement of SPO. Therefore, the nutritional function of SPO has been improved successfully by the application of a microchannel reactor with photo-immobilized lipase, which could set a reference for the utilization of insect oil resources.

A 14 day esomeprazole- and amoxicillin-containing high-dose dual therapy regimen achieves a high eradication rate as first-line anti-Helicobacter pylori treatment in Taiwan: a prospective randomized trial.

BACKGROUND: The first-line eradication rate of standard triple therapy for Helicobacter pylori infection has declined to <80%, and alternative therapies with >90% success rates are needed. Inconsistent eradication rates were reported for proton pump inhibitor- and amoxicillin-containing high-dose dual therapy. OBJECTIVES: We performed a prospective, randomized controlled study to assess the efficacy of esomeprazole- and amoxicillin-containing high-dose dual therapy and investigated the influencing clinical factors. PATIENTS AND METHODS: We recruited 240/278 eligible H. pylori-infected patients after exclusion. They were randomly assigned to 14 day high-dose dual therapy (esomeprazole 40 mg three times daily and amoxicillin 750 mg four times daily for 14 days; EA group) or 7 day non-bismuth quadruple therapy (esomeprazole 40 mg twice daily, clarithromycin 500 mg twice daily, amoxicillin 1 g twice daily and metronidazole 500 mg twice daily for 7 days; EACM group). Urea breath tests were followed up 8 weeks later. RESULTS: The eradication rates for the EA and EACM groups were 91.7% (95% CI = 85.3%-96.0%) and 86.7% (95% CI = 79.3%-92.2%) (P = 0.21) in ITT analysis; and 95.7% (95% CI = 90.2%-98.6%) and 92.0% (95% CI = 85.4%-96.3%) (P = 0.26) in PP analysis. The adverse event rates were 9.6% versus 23.0% in the two groups (P = 0.01). The H. pylori culture positivity rate was 91.8%. The antibiotic resistance rates were amoxicillin, 0%; clarithromycin, 14.6%; and metronidazole, 33.7%. CONCLUSIONS: A 14 day esomeprazole- and amoxicillin-containing high-dose dual therapy achieves a high eradication rate as first-line anti-H. pylori therapy, comparable to that with 7 day non-bismuth quadruple therapy but with fewer adverse events.

Treatment and Cost of Hepatocellular Carcinoma: A Population-Based Cohort Study in Taiwan.

Hepatitis B virus vaccination and antiviral therapies reduce the risk of hepatocellular carcinoma (HCC). However, the lifetime healthcare expenditure involved in caring for HCC patients remains unclear. We examined the use and direct costs of healthcare services for a cohort of HCC patients to the healthcare system using Taiwan national health insurance program research database between 1997 and 2012. Total medical cost for all reimbursed patient encounters, including hospitalizations and outpatient care was cumulated from HCC onset to the end of follow-up or death. The mean follow-up time was 2.7 years (standard deviation, SD = 3.3) for the entire HCC cohort. Insurance payments of approximately US$92 million were made to 5522 HCC patients, with a mean cost of US$16,711 per patient (21,350). On average, the total cost per patient per month was US$2143 (5184); it was 50% higher for advanced cirrhosis patients at the baseline but 23% lower for mild-to-moderate cirrhotic patients. In the two-part regression, patients' underlying comorbid conditions, liver transplants, hepatectomy, and transarterial chemoembolization were associated with increased total cost, with liver transplants having the greatest impact over time. Hepatocellular carcinoma imposes substantial burden on the healthcare system. Real-world evidence on treatment and cost outcomes highlighted the needs to expand effective screening strategies and to optimize healthcare delivery to meet HCC patients' clinical needs.
