RESUMEN
AIMS AND OBJECTIVES: This study aims to analyse the trends in the incidence, prevalence and medical costs of pressure injuries (PIs) among genders in Taiwan. BACKGROUND: The treatment of PIs is complex and costly, often leading to complications and increased mortality. This issue significantly impacts healthcare quality and incurs substantial medical and social costs, warranting attention. METHODS: A retrospective cohort study was conducted using data from Taiwan's National Health Insurance Database to obtain and calculate the incidence, prevalence, and medical costs of PIs in the country between 2001 and 2015 as well as to analyse high-risk groups and the medical care utilisation of patients following the STROBE reporting guidelines. RESULTS: Between 2001 and 2015, 15,327 incident case of PIs were diagnosed. During the study period, the prevalence rate of PIs per 100,000 population rose from 26.3 to 189.6, with approximately 11.5%-16.3% of patients undergoing surgical debridement. The PIs prevalence rate increased by 7.2-fold, and hospitalisation costs accounted for 91.7%-96.0% of the total medical costs. Patients with older age, comorbidities, poorer financial status and lower education levels were found to be likely to develop PIs. These predisposing factors differed between males and females. The prevalence of PIs was higher in patients ≥75 years old than in patients from other age groups. Moreover, PI-related medical expenses have been increasing annually. CONCLUSIONS: In Taiwan, the rising incidence of PIs is driving up medical costs. Effective care and prevention of PIs necessitate a comprehensive plan from the entire healthcare system. RELEVANCE TO CLINICAL PRACTICE: This research fills a gap in the available data on the incidence, prevalence, and medical costs of PIs in Taiwan and Asia. PATIENT OR PUBLIC CONTRIBUTION: The findings can be used to help develop clinical guidelines for preventive education and treatment of PIs.
RESUMEN
OBJECTIVE: Diabetic foot ulcer (DFU) is a common complication in people with diabetes. Standard management includes strict glycaemic management, control of the infection, revascularisation, debridement, mechanical offloading and foot care education. This study aimed to evaluate the efficacy of using topical probiotics in a soybean-based concentrate in the management of DFUs. METHOD: A retrospective, multicentre evaluation of patients with diabetes with non-infected DFUs between October 2020 and October 2021, and who were treated with twice daily topical application of probiotics in a soybean-based concentrate as an adjunct to standard wound care. RESULTS: A total of 22 patients were enrolled into this study, including 16 males and six females, with a mean age of 61 years (range: 31-89 years). Defect size ranged from 1-33.5cm2 (mean: 7.2cm2). The mean number of days until complete healing was 51 (range: 21-112 days). Of the patients, 83% showed complete healing at the end of 16 weeks, 72% showed complete healing at 12 weeks, 56% at eight weeks, and 22% at four weeks. The wounds showed an average decrease in size of 0.59cm2 (9%) per week, calculated using generalised estimating equation. CONCLUSION: This findings of this study provide a new perspective on the therapeutic potential of probiotics as an effective form of management in patients with small, hard-to-heal (chronic) DFUs.

PURPOSE: Investigate the risk of ear-associated diseases after zygomaticomaxillary complex (ZMC) fracture in a population-based retrospective cohort study. MATERIALS AND METHODS: This is a retrospective cohort study using Taiwan's National Health Insurance Research Database of reimbursement claims. A total of 1,330 ZMC fracture patients and 5,320 non-ZMC fracture participants were included and newly developed ear-associated disease data were collected. A Poisson regression and multivariate Cox proportion hazard regression were used for data analysis. RESULTS: The ZMC fracture cohort had a higher incidence of tinnitus than non-ZMC fracture cohort (IRR 1.64, 95 % CI 1.37-1.96), particularly in younger patients (≤34 years of age; IRR 4.05, 95 % CI 3.18-5.15) and male patients (IRR 2.08, 95 % CI 1.12-3.73). ZMC fracture patients also showed a significantly increased risk of having trigeminal neuralgia [IRR 4.06, 95 % CI 3.34-4.94, adjusted HR 4.07 (1.02-16.3)]. For sudden hearing loss and peripheral vertigo, the incidence densities were higher in the ZMC fracture cohort, but these relationships were not significant in the multivariate Cox proportional hazard regression analyses (HR 2.69, 95 % CI 0.76-9.53 for risk of sudden hearing loss; HR 1.36, 95 % CI 0.77-2.40 for risk of peripheral vertigo). CONCLUSIONS: The findings of the study suggest an increased risk of ear-associated diseases among individuals with ZMC fractures, particularly within 2-years follow-ups after injury. We suggest performing detailed examinations for ear-associated diseases in patients with ZMC fractures for early diagnosis and adequate treatment.
RESUMEN
In the present investigation, beta-galactosidase was solubilized into Aerosol OT (AOT)/isooctane reverse micelles. Kinetic data for the hydrolysis of o-nitrophenyl-beta-D-galactopyranoside (ONPG) at different pH values and molar ratios of water to AOT (Wo) were collected. It was observed that the usual kinetic model used for beta-galactosidase catalysis in aqueous systems failed to represent the experimental data. A bounded water model, however, showed a better correlation between enzymatic activity and Wo. In contrast to the aqueous system, controlling the water concentration in the reverse micelles allows the rate constants for the reaction between water molecules and glycosyl-enzyme complexes to be evaluated.
