Does Alcohol Use Influence Hospitalization Outcomes in Adults Suffering Craniomaxillofacial Fractures From Street Fighting?

Study Design: This retrospective cohort study utilized the National Inpatient Sample (NIS) database for the years 2016-2018. Incidences of street fighting were identified using the corresponding ICD-10 codes. Objective: To determine whether alcohol use (measured by blood alcohol content (BAC)) in patients sustaining maxillofacial trauma from hand-to-hand fighting influence hospitalization outcomes. Methods: The primary predictor variable was BAC stratified into six categories of increasing magnitude. The primary outcome variable was mean length of hospital stay (days). The secondary outcome variable was total hospital charges (US dollars). Results: Our final sample consisted of 3038 craniomaxillofacial fractures. Each additional year in age added +$545 in hospital charges (P < .01). Non-elective admissions added $14 210 in hospital charges (P < .05). Patients admitted in 2018 experienced approximately $7537 more in hospital charges (P < .01). Le Fort fractures (+$61 921; P < .01), mandible fractures (+$13 227, P < .01), and skull base fractures (+$22 170; P < .05) were all independently associated with increased hospital charges. Skull base fractures added +7.6 days to the hospital stay (P < .01) and each additional year in patient age added +.1 days to the length of the hospital stay (P < .01). Conclusions: BAC levels did not increase length of stay or hospitalization charges. Le Fort fractures, mandible fractures, and skull base fracture each independently increased hospital charges. This reflects the necessary care (ie, ICU) and treatment (ie, ORIF) of such fractures. Older adults and elderly patients are associated with increased length of stay and hospital charges-they are likely to struggle in navigating the healthcare system and face socioeconomic barriers to discharge.

Resolving the topology of encircling multiple exceptional points.

Non-Hermiticity has emerged as a new paradigm for controlling coupled-mode systems in ways that cannot be achieved with conventional techniques. One aspect of this control that has received considerable attention recently is the encircling of exceptional points (EPs). To date, most work has focused on systems consisting of two modes that are tuned by two control parameters and have isolated EPs. While these systems exhibit exotic features related to EP encircling, it has been shown that richer behavior occurs in systems with more than two modes. Such systems can be tuned by more than two control parameters, and contain EPs that form a knot-like structure. Control loops that encircle this structure cause the system's eigenvalues to trace out non-commutative braids. Here we consider a hybrid scenario: a three-mode system with just two control parameters. We describe the relationship between control loops and their topology in the full and two-dimensional parameter space. We demonstrate this relationship experimentally using a three-mode mechanical system in which the control parameters are provided by optomechanical interaction with a high-finesse optical cavity.

Interest in global surgery rotations among oral and maxillofacial surgical residents in the United States.

PURPOSE: This study sought to assess interest in global surgery rotations among current United States (US)-based oral and maxillofacial surgery (OMS) residents. METHODS: An anonymous 23-question survey was distributed to 633 current OMS residents in the US to examine resident interest in global surgery rotations during residency. The primary outcome variable was resident interest in participating in global OMS rotations during residency training, whereas the primary predictor variable was the presence of residency faculty involved in global OMS work. Descriptive statistics were calculated for all study variables and univariate/multivariate logistic regression analyses were conducted to identify predictors of interest in global OMS rotations. RESULTS: A total of 120 residents with an average age of 30.4 ± 3.2 years responded to the survey. At present, 22 (18.5%) residents stated that their residency programs offer some sort of global OMS rotation and 21 (95.5%) of these claimed they were willing to participate in global OMS rotations at their residency program. Out of the residents who stated their program did not offer a global OMS rotation, 86 (87.8%) respondents stated they would be interested in adding a dedicated global OMS rotation to their residency curriculum. The presence of OMS residency faculty involved in global OMS work (p = 0.030) and a resident's willingness to dedicate vacation time to participate in a global surgery rotation (p = 0.005) were associated with increased interest in a global surgery rotation. CONCLUSION: The majority of respondents would welcome a dedicated global OMS rotation during their residency training.

Hospital Admissions Associated With Head and Neck Injuries From Olympic-style Sports and Activities Between 2010 and 2022.

The objective of this study was to evaluate which Olympic-style sports and activities are most likely to result in hospitalizations relating to head and neck injuries. This was a cross-sectional study using the National Electronic Injury Surveillance System (NEISS) database. Subjects with head and neck injuries from selected Olympic-style sports and activities between 2010 and 2022 were included. Independent variables were demographics and injury characteristics (injury location and sport). The primary outcome variable was hospitalization (yes/no). Survey-weighted descriptive, bivariate, and logistic regression statistics were computed to measure the association between demographic/injury variables and hospitalization. There were 175,995 subjects (national estimate, 5,922,584) meeting inclusion criteria. After adjusting for demographic and injury characteristics, head injuries (odds ratio [OR] = 2.17; 95% CI, 1.83-2.56; P<0.001) demonstrated higher odds of hospitalization compared with facial injuries. Injuries from cycling (OR = 2.52; 95% CI, 2.16-2.95; P<0.001), mountain biking (OR = 2.56; 95% CI, 1.80-3.65; P<0.001), and horseback riding (OR = 4.01; 95% CI, 2.76-5.83; P<0.001) demonstrated higher odds of hospitalization relative to baseball injuries. In conclusion, head and neck injuries associated with high velocity Olympic-style sports and activities such as cycling, mountain biking, and horseback riding had the highest odds of hospitalization.

Risk factors associated with infection in patients sustaining dog bites to the face.

PURPOSE: The purpose of this study is to identify which patient-level factors, if any, influence the risk of infection following dog bite wounds to the face. MATERIALS AND METHODS: This retrospective cohort study was conducted using the Kids' Inpatient Database (KID). The primary predictor variable was the type of facial injury. The primary outcome variable was the presence of facial infection. SPSS was used to perform statistical analyses and statistical significance was set at a P-value of < 0.05. RESULTS: Our final sample comprised a total of 4,420 patients who suffered dog bites to the face, of which 1,237 (28.0%) resulted in infection. Open wound (n = 4,176, 94.5%) was the most common facial injury, followed by bone fractures (n = 105, 2.4%). Relative to children 16-20 years old, children who were 0-5 years old were three times more likely to develop an infection (P < 0.01). Finally, open wounds (P < 0.01) were over seven times more likely to get infected relative to fractures. CONCLUSIONS: Young children, particularly those below the age of five, are vulnerable to dog bite wounds to the face. Open wounds posed the greatest risk of getting infected.

The global reach of social media in oral and maxillofacial surgery.

PURPOSE: Social media use among oral and maxillofacial surgeons (OMSs) has grown in recent years, serving as an important resource for the dissemination of medical/surgical knowledge, research, education, diplomacy, and advocacy. However, no studies have attempted to characterize the global reach of social media in OMS. METHODS: This study examined the profile activity, content performance, and demographic characteristics of followers from a single OMS-related Instagram account. Variables assessed include the total number of followers since the account's inception, profile views over the selected time period, and unique media content posts, as well as likes, comments, saves, impressions, and reach for all media content posts. The top 45 countries, cities, and languages based on each follower's geolocation and user settings were also included. RESULTS: There were 9569 followers of which 6208 (64.9%) were listed as public accounts. Of the 6208 followers with public accounts, 2496 (40.2%) were female. The countries with the most followers included the United States (31.7%), India (12.5%), Malaysia (5.3%), Mexico (4.0%), and Pakistan (3.6%). The cities with the most followers included New York, New York (8.9%), Boston, Massachusetts (5.2%), Cairo, Egypt (4.3%), Santiago, Chile (3.7%), and Karachi, Pakistan (3.5%). CONCLUSION: OMS-related social media is uniquely positioned to facilitate global collaboration and augment the dissemination of surgical knowledge and expertise. This information is critical in understanding the distribution and demographics of the OMS workforce, trainees, and affiliates around the world.

Understanding Health Policy and Its Importance in Residency Education for Oral and Maxillofacial Surgery.

Health policy shapes the delivery of surgical care and the reimbursement of oral and maxillofacial surgeons (OMSs). Understanding broad principles of health policy will better allow surgeons to develop policies that will ultimately affect surgical practice. The growing presence of corporate and private equity investments in OMS practice management as well as expanding interests in value-based reimbursement models has innumerable implications for OMSs and patients. A standardized health policy curriculum for educating OMS trainees in key health policy principles may encourage OMSs to actively participate in health care advocacy efforts and shape the policies that may affect their future scope of practice.

Malar and maxillary fractures among pediatric patients and the risk factors for mortality.

BACKGROUND/AIMS: No studies have characterized the morbidity and mortality of maxillary & malar fractures on a national scale. The aim of this study was to examine the risk factors for mortality in pediatric patients who had sustained maxillary and malar fractures by using a national pediatric hospital inpatient care database. MATERIALS AND METHODS: This retrospective cohort study was conducted using the Kids' Inpatient Database (KID). The primary predictor variable was the cause of injury. The primary outcome variable was mortality rate. Additional predictor variables included age, gender, race, income, payer information, year and place of injury, number of facial fractures, concomitant facial fractures, other fractures of the body, and intracranial/internal organ injury. Univariate and multivariate regression models were performed to assess risk factors for mortality. Statistical significance was set to a p-value <.05. RESULTS: A total of 5859 patients met the inclusion criteria. The most common age group was 13-17 years of age (n = 3816, 65.1%). Motor vehicle accidents were the most common mechanism of injury (n = 2172, 37.1%). The presence of cranial vault (OR = 2.81, p = .017), skull base (OR = 2.72, p < .001), and vertebral column fractures (OR = 2.13, p = .016), as well as sub-arachnoid hemorrhage (OR = 4.75, p = .005), traumatic pneumothorax/hemothorax (OR = 2.16, p = .015), and heart/lung injury (OR = 3.37, p < .001) were each independently associated with increased odds of mortality. CONCLUSIONS: Patients in their late teens most commonly sustained malar and maxillary fractures, likely due to general trends in craniomaxillofacial development. The presence of other fractures located in close proximity to the mid-face increased the risk of mortality among pediatric patients with malar and maxillary fractures. This may be explained by the anatomical approximation of the mid-face to vital neurovascular structures of the head, which, when damaged, may prove fatal.

Measuring the knot of non-Hermitian degeneracies and non-commuting braids.

Any system of coupled oscillators may be characterized by its spectrum of resonance frequencies (or eigenfrequencies), which can be tuned by varying the system's parameters. The relationship between control parameters and the eigenfrequency spectrum is central to a range of applications1-3. However, fundamental aspects of this relationship remain poorly understood. For example, if the controls are varied along a path that returns to its starting point (that is, around a 'loop'), the system's spectrum must return to itself. In systems that are Hermitian (that is, lossless and reciprocal), this process is trivial and each resonance frequency returns to its original value. However, in non-Hermitian systems, where the eigenfrequencies are complex, the spectrum may return to itself in a topologically non-trivial manner, a phenomenon known as spectral flow. The spectral flow is determined by how the control loop encircles degeneracies, and this relationship is well understood for [Formula: see text] (where [Formula: see text] is the number of oscillators in the system)4,5. Here we extend this description to arbitrary [Formula: see text]. We show that control loops generically produce braids of eigenfrequencies, and for [Formula: see text] these braids form a non-Abelian group that reflects the non-trivial geometry of the space of degeneracies. We demonstrate these features experimentally for [Formula: see text] using a cavity optomechanical system.

An Overview of Clinical Oncology and Impact on Oral Health.

As the incidence of cancer continues to increase, so too will the use of various forms of cancer therapeutics and their associated oral and dental complications. Although many of the acute and chronic oral toxicities of cancer therapy are largely unavoidable, appropriate and timely management of these complications has the potential to alleviate morbidity and improve outcomes. Undoubtedly, the substantial short- and long-term impacts of cancer therapy on the health of the oral cavity requires increased awareness, prevention, and treatment by multidisciplinary healthcare teams consisting of medical oncologists, dentists, and other oral healthcare specialists. This mini review provides a brief purview of the current state of clinical oncology and its impact on oral health. The topics introduced here will be further investigated throughout the remainder of the "Oral Complications in Cancer Patients" mini-review series.

Females Have Worse Overall and Disease-Specific Survival in Human Papillomavirus-Negative Oropharyngeal Squamous Cell Carcinoma.

PURPOSE: Although sex (male vs female) has been identified as an independent prognostic factor in human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC), the role of sex in HPV-negative OPSCC is less understood. The purpose of this study is to measure the association between sex and HPV-negative OPSCC disease-specific survival (DSS) and overall survival (OS). METHODS: This longitudinal, retrospective study examined cases of HPV-negative OPSCC diagnosed in the United States between 2013 and 2016 from the Surveillance, Epidemiology, and End Results database. Patients with primary OPSCC and known HPV-negative status were included. Those with HPV-positive or unknown status and primary lesions located outside the oropharynx were excluded. The primary predictor variable was patient sex (male vs female). Primary outcome variables of interest included DSS and OS. The following patient-level covariates were also assessed: age, race, insurance status, primary anatomical site and histological type of lesion, histologic grade and stage, and disease outcome. A survival analysis was conducted using univariate and multivariate analyses via a cox proportional hazard regression model. An α value less than 0.05 was considered statistically significant. RESULTS: The study sample consisted of 2,565 cases (25.1% female) of HPV-negative OPSCC. Females presented with lower histologic grade (P = .015) and earlier stage (P = .003). Females demonstrated worse DSS (P < .001) and OS (P < .001). After multivariate adjustment, female sex (hazard ratio [HR] = 1.38; 95% confidence interval [CI], 1.13 to 1.67; P = .002), advanced age (HR = 1.672; 95% CI, 1.07 to 2.60; P = .023), advanced overall stage (HR = 4.69; 95% CI, 1.54 to 14.267; P = .006), TNM stage (T4: HR = 5.74; 95% CI, 3.86 to 8.55, P < .001, N3: HR = 3.48; 95% CI, 2.17 to 5.58; P < .001, and M1: HR = 2.80; 95% CI, 2.09 to 3.74; P < .001), subjects residing in counties with the highest rates of smoking (HR = 1.29; 95% CI, 1.01 to 1.65; P = .044), and the lack of surgical treatment in patients treated with radiation and/or chemotherapy (HR = 1.44; 95% CI, 1.08 to 1.91; P = .012) were correlated with poorer DSS and OS. CONCLUSION: Females with HPV-negative OPSCC demonstrated worse DSS and OS despite better typical prognostic signs such as histologic grade and clinical stage.

Do rural oral and maxillofacial surgeons prescribe more postoperative opioids?

PURPOSE: This study assesses rural-urban differences in opioid prescription practices among oral and maxillofacial surgeons (OMSs) who treated Medicare beneficiaries in 2017. METHODS: This cross-sectional study examines the 2017 Medicare Provider Utilization and Payment Dataset. The primary predictor variable was provider Rural-Urban Commuting Area code (rural versus urban). The primary outcome variable was mean opioid claims per Medicare beneficiary. Additional outcomes include total opioid claims volume, average Medicare beneficiaries and opioid cost per provider, mean days' supply of opioids per opioid claim, and average percentage of Medicare Part D claims represented by opioid claims. Mann-Whitney U tests compared continuous variables. A least-squares regression identified correlates of opioid claims volume. RESULTS: Rural OMSs demonstrated a higher mean opioid claims per OMS and opioid cost per provider compared to urban surgeons. Urban OMSs prescribed a greater mean days' supply of opioids per opioid claim. A larger percentage of Medicare Part D claims were represented by opioid claims for rural OMSs compared to urban OMSs. There were no differences in mean opioid claims per Medicare beneficiary. Male provider gender, female Medicare beneficiary gender, total number of beneficiaries, and a higher hierarchical condition category score were correlated with increased opioid claims per Medicare beneficiary for urban providers only. CONCLUSION: Urban and rural OMSs prescribe a similar volume of opioids per Medicare beneficiary, with rural providers prescribing higher total volumes of opioids due to larger patient panels. This work indicates that rural and urban OMSs have similar opioid prescribing practices.

Which factors are associated with the number of dental providers employed in correctional settings?

OBJECTIVES: Individuals experiencing incarceration are at increased risk of poor oral health. The purpose of this study was to identify state-level factors that influence the number of oral healthcare providers employed in US correctional settings. METHODS: This ecological study utilized the National Survey of Prison Health Care (NSPHC) to identify the total number of dentists employed in US correctional facilities. Descriptive statistics were calculated and a linear regression was used to identify predictors of the total number of dentists employed in correctional settings by state. RESULTS: The mean number of dentists and dental hygienists/assistants per 10,000 individuals experiencing incarceration was 9.33 ± 4.54 and 11.53 ± 7.02, respectively. The only significant contributor to dental employment was healthcare spending per individual experiencing incarceration (Coefficient = 0.96; p = 0.004). CONCLUSIONS: These findings illustrate the need to develop novel methods of encouraging oral healthcare providers to join the correctional healthcare workforce.

Sicca syndrome associated with immune checkpoint inhibitor therapy.

Cancer immunotherapy, which seeks to stimulate a patient's own immune system to combat cancer, is quickly becoming a central pillar of cancer therapeutics and has resulted in the development of many novel anticancer therapies. One subtype of cancer immunotherapy, immune checkpoint inhibitors (ICIs), has revolutionized cancer treatment and changed the standard of care for multiple indications. However, the advent of ICIs has produced a wide variety of inflammatory side effects termed immune-related adverse events (IRAEs), including ICI-induced Sicca syndrome. This article outlines the clinical features of ICI-induced Sicca syndrome and assesses its reported incidence in clinical trials, case series, and case reports across numerous cancers and treatment modalities. Presentations of ICI-induced Sicca syndrome in patients with pre-existing SjÓ§gren's disease and with extra-glandular manifestations will also be explored. The pathophysiological mechanisms underlying IRAEs, including ICI-induced Sicca syndrome, will be evaluated through an examination of existing literature. Finally, the various treatment and management strategies as well as aims for future work will be discussed and reviewed.

Multi-attribute method performance profile for quality control of monoclonal antibody therapeutics.

Multi-attribute method (MAM) using peptide map analysis with high resolution mass spectrometry is increasingly common in product characterization and the identification of critical quality attributes (CQAs) of biotherapeutic proteins. Capable of providing structural information specific to amino acid residues, quantifying relative abundance of product variants or degradants, and detecting profile changes between product lots, a robust MAM can replace multiple traditional methods that generate profile-based information for product release and stability testing. In an effort to provide informative and efficient analytical monitoring for monoclonal antibody (mAb) products, from early development to manufacturing quality control, we describe the desired MAM performance profile and address the major scientific challenges in MAM method validation. Furthermore, to support fast speed investigational product development, we describe a platform method validation strategy and results of an optimized MAM workflow. This strategy is applied to support the use of MAM for multiple mAb products with similar structures and physicochemical properties, requiring minimal product-specific method validation activities. Three mAb products were used to demonstrate MAM performance for common and representative product quality attributes. Method validation design and acceptance criteria were guided by the Analytical Target Profile concept, as well as relevant regulatory guidelines to ensure the method is fit-for-purpose. A comprehensive system suitability control strategy was developed, and reported here, to ensure adequate performance of the method including sample preparation, instrument operation, and data analysis. Our results demonstrated sufficient method performance for the characteristics required for quantitative measurement of product variants and degradants.
