Secondary Overtriage in Patients with Complicated Mild Traumatic Brain Injury: An Observational Study and Socioeconomic Analysis of 1447 Hospitalizations.
Secondary overtriage is a problematic phenomenon because it creates unnecessary expense and potentially results in the mismanagement of healthcare resources. The rates of secondary overtriage among patients with complicated mild traumatic brain injury (cmTBI) are unknown.
To determine the rate of secondary overtriage among patients with cmTBI using the institutional trauma registry.
An observational study using retrospective analysis of 1447 hospitalizations including all consecutive patients with cmTBI between 2004 and 2013. Data on age, sex, race/ethnicity, insurance status, GCS, Injury Severity Score (ISS), Trauma Injury Severity Score, transfer mode, overall length of stay (LOS), LOS within intensive care unit, and total charges were collected and analyzed.
Overall, the rate of secondary overtriage among patients with cmTBI was 17.2%. These patients tended to be younger (median: 41 vs 60.5 yr; P < .001), have a lower ISS (9 vs 16; P < .001), and were more likely to be discharged home or leave against medical advice.
Our findings provide evidence to the growing body of literature suggesting that not all patients with cmTBI need to be transferred to a tertiary care center. In our study, these transfers ultimately incurred a total cost of 1337 transfer cost) per patient
Fisheries enhancement and restoration in a changing world
Fisheries enhancement is an important strategy for maintaining and improving fisheries productivity, and addressing some of the other contemporary challenges facing marine ecosystems. Aquaculture-based enhancement includes stock enhancement, restocking, and sea ranching. Developments in aquaculture techniques, tagging, genetics, modelling and ecology have underpinned growth in this field in the 21st century, particularly in the context of marine recreational fisheries. Marine enhancement practice has now matured to the point that quantitative tools are frequently applied before any fish or shellfish are released into the natural environment, and pilot-scale enhancement scenarios and release strategies are evaluated before full implementation. Social and economic studies are also increasingly important components of this assessment. Here, several case studies from diverse geographic areas exemplify the union of aquaculture technology, quantitative modelling, social science, physiology and ecology to estimate enhancement potential, improve enhancement strategies, assess enhancement outcomes, and support adaptive management. Integrating aquaculture-based enhancement with habitat enhancement presents a remarkable opportunity for future research and development, and offers the potential to further increase the opportunities and associated socio-economic benefits that are available to a broad range of fisheries stakeholder

Multi-institutional, prospective, randomized, double-blind, placebo-controlled phase IIb trial of the tumor lysate, particle-loaded, dendritic cell (TLPLDC) vaccine to prevent recurrence in high-risk melanoma patients: A subgroup analysis
Background: Checkpoint inhibitors (CPI) in combination with cell-based vaccines may produce synergistic antitumor immunity. The primary analysis of the randomized and blinded phase IIb trial in resected stage III/IV melanoma demonstrated TLPLDC is safe and improved 24-month disease-free survival (DFS) in the per treatment (PT) analysis. Here, we examine efficacy within pre-specified and exploratory subgroups. Methods: Stage III/IV patients rendered disease-free by surgery were randomized 2:1 to TLPLDC vaccine versus placebo. The pre-specified PT analysis included only patients completing the primary vaccine/placebo series at 6 months. Kaplan–Meier analysis was used to compare 24-month DFS among subgroups. Results: There were no clinicopathologic differences between subgroups except stage IV patients were more likely to receive CPI. In stage IV patients, 24-month DFS was 43% for vaccine versus 0% for placebo (p = 0.098) in the ITT analysis and 73% versus 0% (p = 0.002) in the PT analysis. There was no significant difference in 24-month DFS when stratified by use of immunotherapy or CPI. For patients with resected recurrent disease, 24-month DFS was 88.9% versus 33.3% (p = 0.013) in the PT analysis. All benefit from vaccination was in the PT analysis; no benefit was found in patients receiving up to three doses. Conclusion: The TLPLDC vaccine improved DFS in patients completing the primary vaccine series, particularly in the resected stage IV patients. The efficacy of the TLPLDC vaccine will be confirmed in a phase III study evaluating adjuvant TLPLDC + CPI versus Placebo + CPI in resected stage IV melanoma patients. © 2021 The Authors.
