Secure gossip protocol for Cybersecurity Mesh Architecture
No full textModern network infrastructures are evolving toward distributed security models in which verification and control occur across interconnected, heterogeneous nodes. The concept of Cybersecurity Mesh Architecture (CSMA) extends the principles of Zero Trust by decentralizing authentication, policy enforcement, and telemetry sharing. Although CSMA has been widely discussed conceptually, its success depends on the existence of a communication layer that can propagate trust and policy information securely and efficiently among semi-independent devices. At present, no dedicated low-overhead communication protocol has been established for this purpose.
This dissertation addresses that gap by developing and experimentally validating a new framework for secure message dissemination within CSMA. The proposed method, termed Delta-RSSI, introduces a signal-difference–guided gossip protocol that converts variations in received signal strength (RSSI) into reliable spatial fingerprints. By comparing relative rather than absolute RSSI values across monitor nodes, Delta-RSSI removes dependence on device calibration and common-mode channel effects. Each node uses these fingerprints to decide whether to forward or suppress a packet, thereby reducing redundant transmissions while simultaneously identifying abnormal rebroadcast behavior.
By introducing the first communication framework specifically designed for CSMA, this research bridges the theoretical principles of Zero Trust with the practical requirements of distributed, resource-constrained systems. The Delta-RSSI framework establishes a foundation for scalable and secure communication in next generation secure networks

Investigation into the intraoperative management of the difficult pediatric airway: A scoping review
No full textIntroduction/Objectives: Pediatric airways can pose a significant challenge to anesthesia providers. Almost 20% of pediatric patients undergoing general anesthesia are considered to have a difficult airway due to congenital anomalies, craniofacial deformities, trauma, or infection. The majority of children with difficult airways can be identified preoperatively, but the variety of clinical scenarios in which difficult airways can quickly arise requires an individualized approach that considers the underlying condition and the patient’s physiological status. The objective of this scoping review is to identify clinical challenges and complications, summarize outcomes of airway methods, and identify existing knowledge gaps to guide future airway management research.Methods: We performed a literature search using the Ovid (Embase), MEDLINE (PubMed), SCOPUS, Web of Science, and Cochrane databases for articles on pediatric airways that were published in the 10-year period spanning from 2014 to 2024 and written in English. Included studies were systematic reviews, meta-analyses, retrospective database reviews, clinical trials, case-control studies, cross-sectional analyses, and cohort studies. The data was imported into Rayaan, and two independent investigators screened records for inclusion criteria in a masked, duplicate fashion. Investigators then completed a data extraction form that identified the frequencies, types, and complications of airway methods used to provide anesthetic care.Results: The initial database search yielded 1,097 articles, and 82 ultimately met the inclusion criteria to be evaluated in our study. The sample in our study consisted of research from 50 different journals. The most frequent journal featured in our sample was Cureus: Journal of Medical Sciences, with 11 studies (11/82; 13.4%). The continent with the most studies was Asia, with 43 studies (43/82; 52.4%). Case reports/Case series comprised most of the study design types (62/82; 75.6%), followed by Cohort studies (15/82; 18.3%). There was only one of each, a Randomized Controlled Trial and systematic review with meta-analysis. The studies focused on anatomical/congenital difficult airways most commonly (42/82; 51.2%). The approach/technique included in these studies was most commonly direct laryngoscopy (36/82; 43.9%), fiberoptic bronchoscopy (37/82; 45.1%), and video laryngoscopy (39/82; 47.6%).Conclusion: In conclusion, the importance of a proper preoperative examination to identify anatomical, pathological, or physiological characteristics of pediatric patients cannot be emphasized enough. This scoping review provides an overview of the current techniques and methods of intraoperative pediatric difficult airway management and identifies the knowledge gaps and areas for future research. More systematic research, like randomized controlled trials and systematic reviews, could benefit the anesthetic community with different approaches to handling these critical situations
Data sharing practices in pediatric journals
No full textIntroduction: Data sharing is crucial in pediatric research due to the rarity of certain genetic diseases and the limited patient population. Enhanced transparency and reproducibility through data sharing can significantly benefit pediatric studies. Despite its importance, the extent and implementation of DSS in pediatric research remain underexplored. Therefore, we aimed to explore the current landscape of data sharing practices in pediatrics by assessing inclusion of data sharing statements (DSS) in ten of the top pediatric journals.Methods: We conducted an analysis of articles published in ten of the top pediatric journals from January 2020 to December 2023. Data elements were extracted in a masked, duplicate fashion, using a pilot-tested Google Form, and hierarchical logistic regression was employed to analyze the statements, accounting for variability at the journal and publisher levels. Additionally, authors were contacted to assess their willingness to share data upon request.Results: Of the 1,058 articles included in our study, 55.20% included a DSS. Hierarchical logistic regression analysis indicated significant variability with factors such as journal, publisher and study design influencing the inclusion of a DSS. Furthermore, thematic analysis revealed that a large portion of studies’ data are protected by gatekeepers.Conclusions: The prevalence of DSS in pediatric journals is increasing, yet significant barriers to effective data sharing persist. Most DSS involve a gatekeeper role, limiting direct data accessibility. Journal policies significantly influence data sharing practices. To improve transparency and reproducibility in pediatric research, efforts must address data sharing barriers and encourage the use of open data repositories
Usefulness of orthopaedic shoulder surgery trials: Are they meeting key criteria?
No full textBackground: Shoulder surgery is a significant subset of orthopaedic interventions, and randomized controlled trials (RCTs) are critical for advancing surgical techniques and informing clinical guidelines. However, poorly designed or inadequately reported RCTs make applying findings to clinical practice more difficult. This study applies a usefulness assessment tool developed by van’t Hooft et al. to evaluate the utility of shoulder surgery RCTs published in the past five years, aiming to identify trends and gaps to improve trial design and reporting.Methods: This study evaluated RCTs on orthopaedic shoulder surgery published between January 1, 2019, and October 28, 2024. Using Medline and Embase, articles were screened for inclusion based on predefined criteria. Data extraction focused on general trial characteristics and fulfillment of 13 items within the usefulness criteria. Each criterion was scored from 0–2, with a maximum total score of 26. Statistical analysis included descriptive statistics for trial characteristics, linear regression models for scores and time, and a correlation analysis between core usefulness and transparency scores.Results: The mean usefulness score was 13.0/26, with scores ranging from 6 to 23. Core usefulness scores showed a slight decline over time, while transparency scores exhibited an upward trend, leading to a modest overall increase in combined scores. Transparency items, such as conflict of interest and funding disclosures, were well-reported, while public availability of raw data and trial protocols scored poorly. Core usefulness items like problem base and feasibility were widely achieved, but pragmatism and value for money were frequently unmet. A moderate positive correlation (r = 0.29, p = 0.0037) was observed between transparency and core usefulness scores.Conclusions: While transparency improvements have driven slight overall progress in trial quality, substantial gaps remain in key criteria like raw data availability and value for money. The findings highlight the need for journals and researchers to adopt comprehensive strategies to enhance the clinical impact of RCTs. This study underscores the value of structured assessment tools in identifying opportunities to optimize trial design and reporting, ultimately improving evidence-based care in orthopaedic shoulder surgery. The application of the usefulness tool reveals opportunities to strengthen RCT design and reporting, paving the way for more impactful orthopaedic research and better patient outcomes
Effects of sleep on language memory with children with DLD
No full textDLD is a neurodevelopmental condition characterized by difficulties in acquiring and using language, despite normal cognitive development and the absence of hearing impairments. Children with DLD often face challenges in learning new words, expressive and receptive language, attention, and memory. While research has shown that sleep improves word retention in typically developing (TD) children, its impact on children with DLD remains underexplored.Lew Wentz FoundationCommunication Sciences and Disorder
Effectiveness of vestibular rehabilitation therapy in decreasing concussion symptoms in patients under the age of 60: A critically appraised topic
No full textClinical Scenario: Concussions, also known as mild traumatic brain injuries or traumatic brain injuries, are prevalent injuries sustained by both young and old. These injuries can leave people with lasting symptoms. Vestibular Rehabilitation Therapy (VRT) is a form of physical therapy which is comprised of exercises encouraging head and eye movements.Clinical Question: In patients ages twelve to sixty who have sustained a diagnosed concussion and have experienced symptoms for up to one year, does completing vestibular rehabilitation therapy efficiently return them to activities of daily living through symptom resolution sooner than conservative methods?Clinical Bottom Line: There is moderate evidence supporting the integration of VRT to concussion protocols in order to achieve efficient symptom resolution as soon as two weeks to return patients with diagnosed concussions to their activities of daily living.Strength of Recommendation: These findings suggest the Strength of Recommendation Taxonomy (SORT) Level B evidence¹² with a CEBM level 2 indicating the quality methods used by the included studies

Implementing urine microscopy at Oklahoma State University Health Services: A medical student-led quality improvement project
No full textIntroduction/Objectives: Urine microscopy is a low-cost method for evaluating patients with urinary tract infections, metabolic disorders, and kidney disease. Despite clinician request, Oklahoma State University Health Services in Stillwater has not offered urine microscopy for over two years due to a lack of trained lab technicians. The goal of this quality improvement project was to improve one lab technician’s confidence with preparing and reading urine microscopy slides and to refine the training process for future trainees.Methods: Before training, one lab technician rated her perceived confidence levels on a scale of 0 (not at all confident) to 10 (very confident) with sample preparation, microscopy skills, and recognition of urine microscopy features such as cells, casts, and crystals. The trainer and trainee then prepared and reviewed four slides per available urine sample (eight total slides). After this training session, self-reported confidence ratings were measured again. Qualitative feedback regarding urine microscopy training was also collected from the lab technician.Results: Self-reported confidence ratings improved from 5 to 10 forsample preparation, from 0 to 7 for microscopy skills, and from 0 to 5.5 for recognition of urine microscopy features. Feedback for future urine microscopy training included updating the standardized operating procedure, organizing urine microscopy training materials into sections that correlate with the laboratory’s reporting system, and placing printed pictures of common urine microscopy findings near the microscope.Conclusions: Initial urine microscopy training boosted confidence levels considerably. Future work includes implementing suggested changesfor future trainees and pathologist review of prepared slides
Economic assessment of the impact of sire breed and dam weight on the beef industry
No full textThis study examines the potential for misaligned profit incentives between the cow-calf and feedlot sectors by evaluating the effects of mature cow size and breed of sire on economic returns. This study utilizes four years of data collected from birth to rail by the Oklahoma State University Range Cow Research Center. The relationship between phenotypic traits (birth weight, 205-day weaning weight, feedlot entry weight, feedlot exit weight, average daily gain, gain to feed, hot carcass weight, yield grade, fat thickness, ribeye area, marbling score) that drive profits for each sector were estimated with respect to mature cow size and sire breed. Profitability was simulated for both cow-calf and feedlot sectors. Results indicate that in this study cow-calf producers may achieve higher returns with lighter weight dams but face no difference in profits by sire breed. Feedlots may find higher returns purchasing calves out of smaller dams as they have a lower total cost of purchase but similar post-weaning growth when compared to larger calves from larger dams. Given the sires available in the data, Charolais- and Hereford-sired calves achieved higher returns regardless of dam size when compared to Angus-sired calves due to lower total associated costs
