Abstract

Objective: Accurate prediction of hospital length of stay (LOS) following surgical management of oral cavity cancer (OCC) may be associated with improved patient counseling, hospital resource utilization and cost. The objective of this study was to compare the performance of statistical models, a machine learning (ML) model, and The American College of Surgeons National Surgical Quality Improvement Program's (ACS‐NSQIP) calculator in predicting LOS following surgery for OCC. Materials and Methods: A retrospective multicenter database study was performed at two major academic head and neck cancer centers. Patients with OCC who underwent major free flap reconstructive surgery between January 2008 and June 2019 surgery were selected. Data were pooled and split into training and validation datasets. Statistical and ML models were developed, and performance was evaluated by comparing predicted and actual LOS using correlation coefficient values and percent accuracy. Results: Totally 837 patients were selected with mean patient age being 62.5 ± 11.7 [SD] years and 67% being male. The ML model demonstrated the best accuracy (validation correlation 0.48, 4‐day accuracy 70%), compared with the statistical models: multivariate analysis (0.45, 67%) and least absolute shrinkage and selection operator (0.42, 70%). All were superior to the ACS‐NSQIP calculator's performance (0.23, 59%). Conclusion: We developed statistical and ML models that predicted LOS following major free flap reconstructive surgery for OCC. Our models demonstrated superior predictive performance to the ACS‐NSQIP calculator. The ML model identified several novel predictors of LOS. These models must be validated in other institutions before being used in clinical practice. Level of Evidence: 3 Laryngoscope, 134:3664–3672, 2024 [ABSTRACT FROM AUTHOR]

Abstract

Background: To address the rehabilitative barriers to frequency and precision of care, we conducted a pilot study of a biofeedback electropalatography (EPG) device paired with telemedicine for patients who underwent primary surgery +/− adjuvant radiation for oral cavity carcinoma. We hypothesized that lingual optimization followed by telemedicine‐enabled biofeedback electropalatography rehabilitation (TEBER) would further improve speech and swallowing outcomes after "standard‐of‐care" SOC rehabilitation. Method: Pilot prospective 8‐week (TEBER) program following 8 weeks of (SOC) rehabilitation. Results: Twenty‐seven patients were included and 11 completed the protocol. When examining the benefit of TEBER independent of standard of care, "range‐of‐liquids" improved by +0.36 [95% CI, 0.02–0.70, p = 0.05] and "range‐of‐solids" improved by +0.73 [95% CI, 0.12–1.34, p = 0.03]. There was a positive trend toward better oral cavity obliteration; residual volume decreased by −1.2 [95% CI, −2.45 to 0.053, p = 0.06], and "nutritional‐mode" increased by +0.55 [95% CI, −0.15 to 1.24, p = 0.08]. Conclusion: This pilot suggests that TEBER bolsters oral rehabilitation after 8 weeks of SOC lingual range of motion. [ABSTRACT FROM AUTHOR]

Abstract

Background: The high incidence of pediatric acute otitis media (AOM) makes the implications of overdiagnosis and overtreatment far-reaching. Quality indicators (QIs) for AOM are limited, drawing from generalized upper respiratory infection QIs, or locally developed benchmarks. Recognizing this, we sought to develop pediatric AOM QIs to build a foundation for future quality improvement efforts. Methods: Candidate indicators (CIs) were extracted from existing guidelines and position statements. The modified RAND Corporation/University of California, Los Angeles (RAND/UCLA) appropriateness methodology was used to select the final QIs by an 11-member expert panel consisting of otolaryngology—head and neck surgeons, a pediatrician and family physician. Results: Twenty-seven CIs were identified after literature review, with an additional CI developed by the expert panel. After the first round of evaluations, the panel agreed on 4 CIs as appropriate QIs. After an expert panel meeting and subsequent second round of evaluations, the panel agreed on 8 final QIs as appropriate measures of high-quality care. The 8 final QIs focus on topics of antimicrobial management, specialty referral, and tympanostomy tube counseling. Conclusions: Evidence of variable and substandard care persists in the diagnosis and management of pediatric AOM despite the existence of high-quality guidelines. This study proposes 8 QIs which compliment guideline recommendations and are meant to facilitate future quality improvement initiatives that can improve patient outcomes. [ABSTRACT FROM AUTHOR]

Abstract

Throughout the Caribbean region, coastal areas are of vital importance for national incomes from the tourism industry. However, accelerated coastal development has impacted the coastal ecosystems, including the beaches, and deterioration of the shore results from cumulative impacts on both marine and coastal ecosystems. It is essential to identify the areas that need special attention for targeted management plans and actions, especially in areas with high anthropogenic pressure. This research proposes an integrated assessment of the conservation state of shore and coastal ecosystems in the Puerto Morelos National Reef Park (PNAPM) in the Mexican Caribbean, through the spatial monitoring of key parameters. A Geographic Information System (GIS) was employed to analyze the land use on the shore, foredune condition, morphological characteristics of the beaches, shoreline evolution, and the condition of coral reefs and seagrass meadows. The analysis identified the most critical areas in relation to shore deterioration and priority areas for the preservation of ecosystems. The spatial data obtained for the PNAPM can serve as a basis for ongoing shore monitoring, and targeted management actions through the designation of areas that require either preservation or ecosystem restoration practices. This methodology can be applied to other reef systems in the Caribbean. [ABSTRACT FROM AUTHOR]

Abstract

This study explores the use of in situ electrochemical process to regenerate granular activated carbon (GAC) loaded with carbendazim (CBZ) and simultaneously oxidize the contaminant. The experiment optimized the flow rate ($Q$ Q), current density ($j$ j), cathodic or anodic chamber, and electrolyte type to achieve the best results. The study found that using GAC in the cathodic chamber and NaCl as a supporting electrolyte, with a $j$ j = 0.5 mA cm−2, and $Q$ Q = 100 L h−1, led to a 64% regeneration with an energy consumption of 0.15 kWh kg−1, which is at least 16× lower than those found in the literature for electrochemical, microwave and thermal processes. Consecutive regeneration tests revealed a decrease in GAC adsorptive capacity over time due to blockage by transformation products, and mainly by oxidation-induced changes in pore structure, as confirmed in dissolved organic carbon (DOC), scanning electron microscopy (SEM), and surface area results. The results also showed that in all tested conditions, residual CBZ was not found in the electrolyte solution. Overall, electrochemical regeneration proved to be an energy-efficient method for extending the lifespan of GAC and minimizing disposal in landfills. [ABSTRACT FROM AUTHOR]
