9030 Background: HO fellowship programs lack standardized educational approaches. This can impact learning & self-assessment of learning gaps. This study investigates the relationship between HO fellows’ (HOF) comfort levels & objective knowledge assessments across diverse HO topics, addressing a critical need for data in this area. Methods: HOF from 27 U.S. programs were invited to complete an anonymous survey (Sept-Oct 2023) in which they rated their comfort managing representative HO diseases, namely breast cancer (BC), plasma cell dyscrasias (PCD), hemophilia, von Willebrand disease (vWD), & heparin-induced thrombocytopenia (HIT), on a 7-point Likert scale (1 = extremely uncomfortable, 7 = extremely comfortable). An optional multiple choice knowledge quiz on these topics followed, including an option for “not sure & need to look it up.” Fellows were categorized into low (1–3), moderate (4–5), & high (6–7) comfort groups. One-way ANOVA assessed differences in knowledge scores by comfort levels. Results: In total,222 HOF completed the comfort survey (53% response rate): 82 PGY4 (37%), 72 PGY5 (32%), & 69 PGY6+ (31%). Also, 189 HOF completed the knowledge quiz (46% response rate): 71 PGY4 (38%), 57 PGY5 (30%), & 60 PGY6+ (31%). Mean comfort levels (±SD) were: BC diagnosis 4.8±1.4, localized BC management (mgmt.) 4.2±1.5, metastatic BC mgmt. 4.2±1.5, PCD diagnosis 4.8±1.4, MGUS/smoldering myeloma mgmt. 4.7±1.4, front-line myeloma treatment 4.5±1.6, maintenance myeloma treatment 4.1±1.5, inherited/acquired hemophilia mgmt. 3.7±1.5, vWD diagnosis 4±1.4, vWD mgmt. 3.8±1.4, HIT diagnosis 5.4±1.1, & HIT mgmt. 5.4±1.1. Mean knowledge scores were 41% for BC, 39% for PCD, 47% for hemophilia, 33% for vWD, & 51% for HIT. When evaluated by comfort level groups (low, medium, & high), knowledge scores increased significantly with higher comfort levels for BC (25%, 43%, 55%; p<0.01), PCD (25%, 38%, 51%; p<0.01), hemophilia (29%, 55%, 77%; p<0.01), & vWD (13%, 39%, 62%; p<0.01). HIT scores showed no significant difference by comfort levels (p=0.89). The number of “not sure” responses (%) significantly decreased (p<0.01) with greater comfort across topics: BC (53%, 20%, 10%), PCD (39%, 23%, 7%), hemophilia (52%, 28%, 2%), vWD (69%, 40%, 12%). HIT “not sure” responses showed no significant difference by comfort levels. Conclusions: This multicenter analysis demonstrates a correlation between HOF comfort levels & knowledge assessments. Despite overall low performance on knowledge tests, comfort levels effectively discriminated between knowledge groups, underscoring their potential utility as a surrogate for educational progress. These data highlight the need for interventions to bridge gaps between perceived & actual knowledge. Future studies to validate these results across broader topics & institutions to inform optimal education strategies in HO training programs are needed.

The rising popularity of martial arts has unfortunately led to a surge in injuries, particularly in the head and neck. Craniofacial injuries, a common occurrence in mixed martial arts (MMA), necessitate a closer look. By studying these injuries, the authors can identify gaps in diagnosis and treatment, and more importantly, the authors can take steps to prevent future injuries. This includes advocating for increased safety measures and risk reduction through the Consumer Product Safety Commission. The National Electronic Injury Surveillance System database was analyzed from 2014 to 2023 to collect data on head and neck injuries related to martial arts equipment within the last 10 years. This data set conveys patient information, such as sex, race, weight, age, diagnosis, treatment date, body part, disposition, and injury location, that occurred while competing in MMA. Over the most recent 10 years, an estimated 54,787 cases of craniofacial injury due to MMA were reported to the emergency department, with a majority taking place in 2022 (6880 cases/12.6% of all cases). Men were 3.69 times more likely to get injured than women. The 10-year age group with the most injuries was 20 to 29 (18,182 cases/34.3%), but the age with the most cases was 15 years old (2349 cases/6.7%). The most common location of craniofacial injury was the head (22,214 cases/39.3%), and the most common diagnosis was internal injury (11,034 cases/19.5% of all cases). The overwhelming majority of cases had no hospitalization (52,023 cases/95.0% of all cases). This study underscores the significant occurrence of craniofacial injuries in the context of MMA over the past decade. It provides novel insights into preventative strategies, epidemiology, and disposition of these injuries. The results reveal a spectrum of damage, from low to high severity, and a predilection for adolescent and young adult males. This study advocates for stricter regulations, better protective gear, and increased awareness of safety standards to ensure the well-being of MMA athletes. Future research should focus on post-injury recovery and long-term outcomes to further mitigate risks and enhance the safety of this demanding sport.

This study analyzes current models of cybersecurity maturity and modifies them to fit the specific requirements and limitations of online startups and small businesses. As part of the process, a comparison of current models and suggestions for a customized model suitable for new digital enterprises is presented.

Bot trading, or algorithmic trading, has transformed modern financial markets by using advanced technologies like artificial intelligence and machine learning to execute trades with unparalleled speed and efficiency. This paper examines the mechanisms and types of trading bots, their impact on market liquidity, efficiency, and stability, and the ethical and regulatory challenges they pose. Key findingshighlight the dual nature of bot trading—enhancing market performance while introducing systemic risks, such as those observed during the 2010 Flash Crash. Emerging technologies like blockchain and predictive analytics, along with advancements in AI, present opportunities for innovation but also underscore the need for robust regulations and ethical design. To provide deeper insights, we conducted an experiment analyzing the performance of different trading bot strategies in simulated market conditions, revealing the potential and pitfalls of these systems under varying scenarios.

Most administrators prefer using Enterprise Manager to monitor and administer databases. The web user interface is a simplified way to monitor databases over using the command line. In addition, identifying bottlenecks using graphs is easier than checking text or XML versions of log files and comparing logged metrics and values. Graphs help you easily identify a maximum value for the specific threshold and switch to the tuning page.

The objective of this study was to utilize electronic health records to determine the incidence of opiate prescription following diagnosis of a sleep related disorder. Opiate use disrupts sleep architecture triggering sleep disturbances, and neurobiological mechanisms exist through which sleep disorders modify opiate reward pathways. We hypothesized patients with sleep disorders will have increased opiate prescriptions following diagnosis. We used data from the TriNetX electronic health records network which includes over 80 million patients from 57 health care organizations across the world. We compared adult patients with the most common sleep disorders against adults with negative polysomnography. Patients with a sleep disorder were more likely to use opioids than those without a sleep disorder (RR 1.39, 95% CI 1.35, 1.44). Patients with a sleep disorder also had significantly more unique opiate uses in their medical record (2.56, sd 12.18, p < 0.001) compared to individuals without a sleep disorder (1.101, sd 5.57). Sleep disorder patients also used an opiate closer to the date of their sleep assessment compared to patients without a sleep disorder (median 2078 and 3345 days, respectively). These results support our hypothesis of increased opiate use by patients with a sleep disorder. Sleep disorder patients are more likely to receive opiates, receive a higher quantity, and receive them closer to their sleep assessment. These results support that the association between opiates and nighttime breathing disorders is bidirectional.

In anticipation of that direct examination of the shear flow affection on the dynamic viscoelasticity might bring more comprehensive results than the LAOS method, a series of dynamic viscoelasticity measurements with parallel superposition of steady shear flow was planned. The measured values which are function of shear rate ̇γ, that is, storage and loss moduli G′(̇γ), G″(̇γ) and viscosity η(̇γ), are analyzed as three non-dimensional parameters G′(̇γ) / G′(0), G″(̇γ) / G″(0) and η(̇γ) / | η*(ω, ̇γ) |, where η* is complex viscosity. A Couette rheometer ONRH-1b (OhnaTech) was employed, and for the samples, hydroxypropyl cellulose, xanthan gum, carboxyvinyl polymer and C24-hydrophobically modified ethoxylated urethane ware used. All three analyzing parameters show clearly the differences of samples. It is found that the nature of their responses are subjected not by the shear itself, but by the value that divided shear rate with measure frequency (̇γ/ω). On the other hand, it is found that the properties that are subjected by the shear rate do exist. Observation of these results asserts that multifactorial rheological measurement including this superposition method is worthwhile.

To tune index usage, it’s important to understand the various types of index access paths available to the cost optimizer. This chapter summarizes the most important index access paths available to the optimizer. Often, Oracle database administrators are bewildered when the optimizer chooses not to use what they believe is a very useful index, but does a full table scan instead. This chapter devotes attention to exploring some reasons why the optimizer might prefer a full table scan to using an index. You’ll also learn how to force the optimizer to use (or not to use) an index. Oracle provides a large number of index-related hints to enable you to control the behavior of the optimizer regarding index usage. You’ll find descriptions of the key index-related hints in this chapter.

ObjectivesCurrent research efforts are centered on delineating the novel health benefits of naturally derived saccharides, including growing interest in their abilities to influence neurologic health. We performed a comprehensive review of the literature to consolidate all controlled studies assessing various roles of exogenous saccharide compounds and polysaccharide-rich extracts from plants, fungi, and other natural sources on brain function, with a significant focus on benefits derived from oral intake.MethodsStudies were identified by conducting electronic searches on PubMed and Google Scholar. Reference lists of articles were also reviewed for additional relevant studies. Only articles published in English were included in this review.ResultsSix randomized, double-blind, placebo-controlled clinical studies were identified in which consumption of a blend of plant-derived polysaccharides showed positive effects on cognitive function and mood in healthy adults. A separate controlled clinical study observed improvements in well-being with ingestion of a yeast beta-glucan. Numerous animal and in vitro studies have demonstrated the ability of individual saccharide compounds and polysaccharide-rich extracts to modify behavior, enhance synaptic plasticity, and provide neuroprotective effects.DiscussionAlthough the mechanisms by which exogenous saccharides can influence brain function are not well understood at this time, the literature suggests that certain naturally occurring compounds and polysaccharide-rich extracts show promise, when taken orally, in supporting neurologic health and function. Additional well-controlled clinical studies on larger populations are necessary, however, before specific recommendations can be made.
