Multisystem Inflammatory Syndrome in Children.

Multisystem inflammatory disease in children (MIS-C) is a condition typically seen 3 to 6 weeks after acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Believed to be a postinfection hyperinflammatory response, the clinical manifestation of this viral sequelae can vary significantly in severity and symptomatic presentation. Clinical prodrome includes persistent fever and dysfunction of at least two organ systems. Often developing after asymptomatic or mildly symptomatic coronavirus disease 2019 (COVID-19) infection, MIS-C is a diagnosis of exclusion that requires evaluation for other infectious or noninfectious etiology for symptoms. Vital sign instability, including fever, tachycardia, and hypotension; laboratory studies demonstrating elevated inflammatory markers and elevated cardiac markers; and positive SARS-CoV-2 polymerase chain reaction, SARS-CoV-2 antibodies, or exposure to someone with confirmed COVID-19 infection 4 to 6 weeks before clinical presentation are used to diagnose this condition. Skin and mucosal involvement, gastrointestinal symptoms, and neurologic manifestations are also commonly seen. An echocardiogram is indicated to evaluate for cardiac dysfunction, including but not limited to coronary artery enlargement, left ventricular dysfunction, arrythmias, or atrioventricular block.

Inpatient Understanding of Their Care Team and Receipt of Mixed Messages: a Two-Site Cross-Sectional Study.

BACKGROUND: Patient understanding of their care, supported by physician involvement and consistent communication, is key to positive health outcomes. However, patient and care team characteristics can hinder this understanding. OBJECTIVE: We aimed to assess inpatients' understanding of their care and their perceived receipt of mixed messages, as well as the associated patient, care team, and hospitalization characteristics. DESIGN: We administered a 30-item survey to inpatients between February 2020 and November 2021 and incorporated other hospitalization data from patients' health records. PARTICIPANTS: Randomly selected inpatients at two urban academic hospitals in the USA who were (1) admitted to general medicine services and (2) on or past the third day of their hospitalization. MAIN MEASURES: Outcome measures include (1) knowledge of main doctor and (2) frequency of mixed messages. Potential predictors included mean notes per day, number of consultants involved in the patient's care, number of unit transfers, number of attending physicians, length of stay, age, sex, insurance type, and primary race. KEY RESULTS: A total of 172 patients participated in our survey. Most patients were unaware of their main doctor, an issue related to more daily interactions with care team members. Twenty-three percent of patients reported receiving mixed messages at least sometimes, most often between doctors on the primary team and consulting doctors. However, the likelihood of receiving mixed messages decreased with more daily interactions with care team members. CONCLUSIONS: Patients were often unaware of their main doctor, and almost a quarter perceived receiving mixed messages about their care. Future research should examine patients' understanding of different aspects of their care, and the nature of interactions that might improve clarity around who's in charge while simultaneously reducing the receipt of mixed messages.

Clinical Predictors of Postintubation Bilateral Vocal Fold Immobility

Abstract Introduction Iatrogenic bilateral vocal fold immobility (BVFI) often arises from posterior glottic stenosis (PGS) after endotracheal intubation, whereby posterior commissure mucosal disruption leads to fibrosis and ankylosis of the cricoarytenoid joints. Sequelae can be devastating, resulting in dyspnea, stridor, and death due to asphyxiation. Objectives We sought to review features associated with PGS to better understand how to prevent this condition. A secondary aim is to analyze factors correlating to tracheostomy dependence. Methods Charts from January 2010 to November 2020 were retrospectively reviewed, and adult patients with the diagnosis of BVFI after intubation were included. Data on comorbidities, duration of intubation, laryngoscopy, and decannulation status was analyzed. Results Out of the 68 patients included in the present study, 60.3% were male, and the mean duration of intubation 14.3 ± 8.5 days. A total of 94% of the patients were intubated for at least 7 days, diabetic, and/or obese. Although association with prolonged intubation >7 days was not significant (p = 0.064), complete BVFI on fiberoptic exam (n = 47) was significantly associated with tracheostomy dependence both in the entire cohort (p = 0.036) and in the 56 patients with tracheostomy (p = 0.0086). Patients without cardiovascular disease (CVD) were less likely to be tracheostomy dependent compared with those with CVD (odds ratio [OR]: 0.23 [0.053-0.79]; p = 0.028). Conclusions We identified duration of intubation, DM, and obesity as potential risk factors for PGS. Complete immobility and CVD were significantly associated with tracheostomy dependence. Our findings may have important implications for earlier tracheostomy in high-risk intubated patients, as well as for closer monitoring of disease progression and earlier intervention in those predisposed to tracheostomy dependence.

Merlin-Deficient Schwann Cells Are More Susceptible to Radiation Injury than Normal Schwann Cells In Vitro.

Objectives Vestibular schwannomas (VS) are intracranial tumors, which are caused by NF2 gene mutations that lead to loss of merlin protein. A treatment for VS is stereotactic radiosurgery, a form of radiation. To better understand the radiobiology of VS and radiation toxicity to adjacent structures, our main objectives were (1) investigate effects of single fraction (SF) radiation on viability, cytotoxicity, and apoptosis in normal Schwann cells (SCs) and merlin-deficient Schwann cells (MD-SCs) in vitro, and (2) analyze expression of double strand DNA breaks (γ-H2AX) and DNA repair protein Rad51 following irradiation. Study Design This is a basic science study. Setting This study is conducted in a research laboratory. Participants Patients did not participate in this study. Main Outcome Measures In irradiated normal SCs and MD-SCs (0-18 Gy), we measured (1) viability, cytotoxicity, and apoptosis using cell-based assays, and (2) percentage of cells with γ-H2AX and Rad51 on immunofluorescence. Results A high percentage of irradiated MD-SCs expressed γ-H2AX, which may explain the dose-dependent losses in viability in rodent and human cell lines. In comparison, the viabilities of normal SCs were only compromised at higher doses of radiation (>12 Gy, human SCs), which may be related to less Rad51 repair. There were no further reductions in viability in human MD-SCs beyond 9 Gy, suggesting that <9 Gy may be insufficient to initiate maximal tumor control. Conclusion The MD-SCs are more susceptible to radiation than normal SCs, in part through differential expression of γ-H2AX and Rad51. Understanding the radiobiology of MD-SCs and normal SCs is important for optimizing radiation protocols to maximize tumor control while limiting radiation toxicity in VS patients.

Indications and outcomes for elective dissection of level V in primary parotid cancer.

BACKGROUND: The extent of cervical lymphadenectomy required for primary parotid cancer is not well-established. METHODS: In this retrospective case-control study, 84 patients who underwent primary parotidectomy and neck dissection for primary parotid cancer between 2010 and 2019 were identified and analyzed. RESULTS: Of the 84 patients, 37 underwent elective level V neck dissection. All six (16.0%) who had occult level V nodes had clinically evident, preoperative anterior cervical metastases, a statistically significant finding. No other clinical factors are correlated with posterior neck involvement. There was no significant difference in disease-free or overall survival for patients with occult level V disease relative to positive lymph nodes in other levels. CONCLUSIONS: Patients with clinically evident anterolateral cervical lymphatic metastases from parotid cancer preoperatively have high rates of occult level V nodes. Level V neck dissection can be avoided in cN0 patients and offered no survival advantage.

Redefining Perineural Invasion in Head and Neck Cutaneous Squamous Cell Carcinoma.

OBJECTIVE: Perineural invasion (PNI) negatively affects disease-specific survival in patients with head and neck cutaneous squamous cell carcinoma (HNcSCC). We aim to analyze the prognostic implications of PNI-related features. STUDY DESIGN: Retrospective cohort study. SETTING: Academic tertiary care hospital. METHODS: Retrospective chart review was performed on 104 patients diagnosed with HNcSCC between January 2011 and October 2019 who underwent resection, parotidectomy, and neck dissection with more than 1 year of follow-up. PNI was classified as incidental (identified on histopathology alone) or clinical (present on radiography and/or physical exam). Primary outcome measures were overall survival and disease-free survival (DFS). Kaplan-Meier analysis, logistic regression, and Cox regression were performed. RESULTS: The overall 5-year DFS was 57.9%. Sixty-one patients had PNI. On histopathology, 28 lesions showed complete nerve encirclement, 10 involved >5 nerves, and 12 involved named nerves. Patients with facial weakness (P = .026) and positive margins (P = .0029) had a higher likelihood of histopathologic PNI, and positive margins retained significance on multivariable analysis (P = .0079). Worse DFS was seen in patients with PNI (P = .004), advanced tumor stage (P = .049), positive margins (P = .014), and >5 nerves involved (P = .0061). Furthermore, histopathologic PNI was a predictor of DFS (hazard ratio [HR], 3.07; 95% CI, 0.33-1.38; P = .0061) overall and in the clinical PNI cohort (HR, 3.43; 95% CI, 1.65-7.10; P = .00091). CONCLUSION: DFS was significantly worse in patients with PNI, facial nerve weakness, advanced T stage, positive margins, and multiple nerve involvement. Further characterization of PNI features may help improve prognostic predictions and identify patients who may benefit from more aggressive treatment.

N95 vs Half-face Respirator Wear in Surgical Trainees: Physiologic and Psychological Effects of Prolonged Use.

OBJECTIVES: As specialists of the upper airway, otolaryngologists are at high risk for COVID-19 transmission. N95 and half-face respirator (HFR) masks are commonly worn, each with advantages in functionality and comfort. In this study, physiologic and psychological parameters of prolonged N95 vs HFR wear were compared. STUDY DESIGN: Prospective crossover cohort study. SETTING: Single academic tertiary care hospital. METHODS: A prospective crossover cohort study was performed. Healthy otolaryngology trainees and medical students (N = 23) participated and wore N95 and HFR masks continuously for 3 hours each on separate days. Various measures were analyzed: vitals, spirometry variables, scores on the State-Trait Anxiety Inventory and HIT-6 (Headache Impact Test-6), distress, and "difficulty being understood." RESULTS: The average age was 26.3 years (SD, 3.42). There were no significant differences in vital signs and spirometry variables between N95 and HFR wear. N95 wear was associated with decreases in oxygen saturation of approximately 1.09% more than with HFRs (95% CI, 0.105-2.077). State-Trait Anxiety Inventory scores increased more with HFR wear when compared with mean changes with N95 wear (95% CI, 1.350-8.741). There were no significant differences in HIT-6 scores or distress levels between masks. The proportions of participants reporting difficulty being understood was significantly higher with HFRs. CONCLUSIONS: Oxygen saturation decreases with prolonged N95 wear, but anxiety and difficulty being understood are greater with HFR wear. Although HFRs have less resistance to gas exchange, N95 respirators may produce less anxiety and distress in clinical situations. Further studies are warranted to evaluate the clinical significance of these differences. LEVEL OF EVIDENCE: 2.

Understanding the Radiobiology of Vestibular Schwannomas to Overcome Radiation Resistance.

Vestibular schwannomas (VS) are benign tumors arising from cranial nerve VIII that account for 8-10% of all intracranial tumors and are the most common tumors of the cerebellopontine angle. These tumors are typically managed with observation, radiation therapy, or microsurgical resection. Of the VS that are irradiated, there is a subset of tumors that are radioresistant and continue to grow; the mechanisms behind this phenomenon are not fully understood. In this review, the authors summarize how radiation causes cellular and DNA injury that can activate (1) checkpoints in the cell cycle to initiate cell cycle arrest and DNA repair and (2) key events that lead to cell death. In addition, we discuss the current knowledge of VS radiobiology and how it may contribute to clinical outcomes. A better understanding of VS radiobiology can help optimize existing treatment protocols and lead to new therapies to overcome radioresistance.

Hemorrhagic Shock after Neonatal Circumcision: Severe Congenital Factor XIII Deficiency.

A Caucasian male infant born full term via normal spontaneous vaginal delivery was given vitamin K after birth, circumcised on day of life (DOL) 1, and discharged from the nursery on DOL 2. At the time of circumcision, oozing from the surgical site was noted and initially resolved with silver nitrate. Over the next two days, he presented to local emergency rooms multiple times for recurrent bleeding, eventually developing hemorrhagic shock resulting in admission to the neonatal intensive care unit. After extensive work up, he was ultimately diagnosed with severe congenital factor XIII deficiency. Congenital factor XIII deficiency is a rare bleeding disorder characterized by normal prothrombin time (PT) and activated partial thromboplastin time (aPTT) coagulation labs on routine screening, and has a high risk of complications, such as spontaneous intracranial hemorrhage. Although uncommon, when caring for a child with bleeding, physicians must have a high index of suspicion to make this diagnosis in order to initiate proper treatment and start prophylaxis given the risk of morbidity and mortality in untreated patients.

Green Salad Intake Is Associated with Improved Oral Cancer Survival and Lower Soluble CD44 Levels.

Deficiencies in fruit and vegetable intake have been associated with oral cancer (oral cavity and oropharyngeal). Salivary rinses contain measurable biomarkers including soluble CD44 (solCD44) and total protein, which are known markers of oral cancer risk. This study investigates the effect of nutritional factors on solCD44 and protein levels to evaluate oral cancer risk and survival. We evaluated solCD44 and protein levels from 150 patients with oral and oropharyngeal squamous cell carcinoma and 150 frequency-matched controls. We subsequently characterized the effect of food group consumption and these biomarkers on progression-free survival (PFS) and overall survival (OS). Patients reported eating fewer servings of salad (p = 0.015), while controls reported eating fewer servings of potatoes (p < 0.001). Oral cancer patients who consumed at least one serving per week of green salad were found to have significantly lower CD44 levels than those who ate salad less frequently (mean of log2[solCD44]1.73 versus 2.25, p = 0.014). Patients who consumed at least one serving per week of "salad or other vegetables" had significantly longer PFS (median 43.5 versus 9.1 months, p = 0.003, adjusted hazard ratio (HR) = 0.39 p = 0.014) and OS (median 83.6 versus 10 months, p = 0.008, adjusted HR = 0.04 p = 0.029). These findings suggest that dietary factors, namely greater green salad and vegetable intake, may be associated with lower CD44 levels and better prognosis in oral cancer patients.

Free tissue reconstruction of the anterior skull base: A review.

OBJECTIVE: There has been a significant shift from open craniofacial resection of the anterior skull base to endoscopic approaches that accomplish the same outcomes in tumor ablation. However, when open resection is required, free flap reconstruction is often necessary to provide sufficient well-vascularized tissue for optimal wound healing as well as providing adequate tissue bulk for cosmesis. This articleaims to providea focused review of free flaps most commonly used in anterior skull base reconstruction. METHODS: This is a state-of-the-art review based on expert opinion and previously published reviews and journal articles, queried using PubMed and Google Scholar. RESULTS & CONCLUSION: Anterior skull base reconstruction via free tissue transfer is imperative in limiting complications and promoting healing, particularly with large defects, post-radiation, and in at-risk patients. The type of free flap utilized for a particular anterior skull base reconstruction should be tailored to the patient and nature of the disease. This review offers insight into the numerous reconstructive options for the free flap surgeon.

CD44 and associated markers in oral rinses and tissues from oral and oropharyngeal cancer patients.

OBJECTIVES: Oral and oropharyngeal squamous cell carcinoma (OOPSCC) is a debilitating disease. Salivary rinses contain soluble tumor markers including CD44 (solCD44) and total protein (TP) that may aid detection and prognosis of these aggressive tumors. Here we aim to examine the relationship between these salivary biomarkers and tissue markers p16 and CD44 and determine whether these markers can predict progression-free survival (PFS) and overall survival (OS). MATERIALS AND METHODS: Prospective study to update biomarkers using oral rinses and tissues from OOPSC patients enrolled between 2007 and 2012 at an academic tertiary referral center. 64 cases from a 300-subject case-control study with archived tissue for immunohistochemistry were included. RESULTS: 82.8% were male, 84.4% were ever smokers, 70.3% had disease stage T3-T4, and 57.8% presented with nodal disease. Nineteen patients (25%) were p16 positive. The group with strong tissue CD44 expression in membrane and cytoplasm had higher levels of solCD44 (mean 10.73 ng/ml) than other groups (5.47 ng/ml) (p = 0.033). TP levels were significantly reduced in oral rinses from subjects with p16 universal gross tumor tissue staining (mean 0.80 vs. 1.08 mg/ml; p = 0.039). On multivariate analysis, universal CD44 gross tissue staining and TP levels ≥ 1 mg/ml demonstrated poorer PFS, with the latter also affecting OS. Poorer survival was associated with soluble CD44 ≥ 5.33 ng/ml and TP ≥ 1 mg/ml. CONCLUSIONS: Direct associations were found between high solCD44 levels and strong membrane and cytoplasmic CD44 expression, and between high TP levels and peripheral/mixed p16 gross staining. Poorer PFS and OS are significantly associated with higher levels of solCD44 and protein in oral rinses.

P16 and human papillomavirus in sinonasal squamous cell carcinoma.

Human papillomavirus (HPV) in oropharyngeal squamous cell carcinoma (SCC) is a well-known cause and prognostic indicator, and the utility of p16 as a surrogate marker for HPV status has been established. P16 and its relationship with HPV have not been defined in sinonasal malignancy nor has a link with outcomes been established. Patients with sinonasal SCC from 2011 to 2017 were identified from our pathology database. P16 immunohistochemistry and HPV RNA in situ hybridization were performed on tissue specimens. Forty-seven patients were included. Disease-free survival for p16+ patients was significantly higher than p16- patients (P = .043). Fewer HPV+ patients died (P = .052) or experienced recurrence (P = .0437). Odds ratio between p16 and HPV status was 14.19 (95% CI: 1.72, 442.03). Our findings demonstrate improved survival in both the p16+ and HPV+ groups and a positive association between p16 and HPV. There may be similar potential for modifying classification for HPV+ sinonasal SCC.

Feminization of Transgender Women With Thyroid Chondroplasty and Laryngoplasty.

In recent years, gender affirmation surgery has broadened significantly from its previous focus on genital conformation only to include other areas of the body as well. As society reconsiders its interpretations of masculinity, femininity, and gender definitions, transgender individuals have realized that they will only be able to truly transition if they are recognized by the public in their chosen societal role. The authors review the literature and describe their own techniques for feminizing thyroid chondroplasty and laryngoplasty.

Assessment of human papillomavirus awareness in association with head and neck cancer at a screening event.

OBJECTIVES/HYPOTHESIS: To assess the baseline awareness of human papillomavirus (HPV) infection as a cause of head and neck cancer (HNC) to design improved targeted screening and education efforts. STUDY DESIGN: Retrospective review of collected survey at a cancer screening event. METHODS: This was a screening event at three hospitals and one community center in Miami, Florida. Participants were recruited throughout the Greater Miami area. Descriptive statistics were used to summarize the demographic characteristics of those who were aware of HPV and those who were not. Adjusted odds ratios, odds ratios, and χ2 tests were used in statistical analysis. RESULTS: A total of 196 women and 112 men were screened across four sites, with 187 participants at hospital-based events and 124 participants at the community-based event. Forty percent of respondents had heard of HPV, and 28.0% identified HPV as a risk factor for HNC. Non-Hispanic and Hispanic respondents were 3.309 and 2.445 times, respectively, more likely than Haitian respondents to have heard of HPV. Women were 2.488 times more likely than men to be aware of HPV. College graduates were 2.268 times more likely than those with less than a college degree to be aware of HPV. Younger respondents were more likely to be aware of HPV. Of those who identified HPV as a risk factor for HNC, 95.4% also correctly identified smoking and 75.9% also correctly identified alcohol as risk factors. CONCLUSIONS: Disparities in HPV and HNC awareness were noted between gender, age, education level, and ethnicity. LEVEL OF EVIDENCE: NA. Laryngoscope, 128:386-392, 2018.

Immunohistochemistry Analysis of CD44, EGFR, and p16 in Oral Cavity and Oropharyngeal Squamous Cell Carcinoma.

Objectives We analyze the relationship between CD44, epidermal growth factor receptor (EGFR), and p16 expression in oral cavity and oropharyngeal cancers in a diverse population. We also describe whether particular patterns of staining are associated with progression-free survival and overall survival. Study Design Prospective study, single-blind to pathologist and laboratory technologist. Setting Hospital based. Subjects and Methods Immunohistochemistry, comprising gross staining and cellular expression, was performed and interpreted in a blinded fashion on 24 lip/oral cavity and 40 oropharyngeal cancer specimens collected between 2007 and 2012 from participants of a larger study. Information on overall survival and progression-free survival was obtained from medical records. Results Nineteen cases were clinically p16 positive, 16 of which were oropharyngeal. Oral cavity lesions were more likely to exhibit strong CD44 membrane staining ( P = .0002). Strong CD44 membrane and strong EGFR membrane and/or cytoplasmic staining were more common in p16-negative cancers ( P = .006). Peripheral/mixed gross p16 staining pattern was associated with worse survival than the universal staining on univariate and multivariate analyses ( P = .006, P = .030). This held true when combining gross and cellular localization for p16. For CD44, universal gross staining demonstrated poorer overall survival compared with the peripheral/mixed group ( P = .039). CD44 peripheral/mixed group alone and when combined with universal p16 demonstrated the best survival on multivariate analysis ( P = .010). Conclusion In a diverse population, systematic analysis applying p16, CD44, and EGFR gross staining and cellular localization on immunohistochemistry demonstrates distinct patterns that may have prognostic potential exceeding current methods. Larger studies are warranted to investigate these findings further.

Insulin provision therapy and mortality in older adults with diabetes mellitus and stable ischemic heart disease: Insights from BARI-2D trial.

IMPORTANCE: Optimal strategies for glucose control in very old adults with diabetes and stable ischemic heart disease (SIHD) are unclear. OBJECTIVE: To compare the effects of insulin provision (IP) therapy versus insulin sensitizing (IS) therapy for glycemic control in older (≥75years) and younger (<75years) adults with type II diabetes (DM) and SIHD. DESIGN, SETTING, AND PARTICIPANTS: Adults enrolled in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) were studied. The BARI 2D study population (all with type II DM and SIHD) was randomized twice: (1) between revascularization plus intensive medical therapy versus intensive medical therapy alone, and (2) between IP versus IS therapies. The primary endpoint was all-cause-mortality over five-year follow-up. In this substudy outcomes related to IP vs. IS are assessed in relation to age. Adults aged ≥75years who received IP versus IS are compared to those <75years who received IP versus IS. Multivariate Cox regression analysis was used to evaluate the effects of IP vs. IS on outcomes in the two age groups. RESULTS: 2368 subjects with SIHD and DM were enrolled in BARI 2D; 182 (8%) were ≥75years. Compared to younger subjects, the older cohort had lower BMI, higher diuretic use, worse kidney function, and increased history of heart failure. Within the older cohort, the IP and IS subgroups were similar in respect to baseline cardiovascular risk factors, medications, and coronary artery disease severity. During follow-up, the older subjects receiving IP therapy had higher cardiovascular mortality compared to those receiving IS therapy (16% vs. 11%, p=0.040). Using Cox proportional hazards analysis, the older IP subjects were at increased risk for all-cause-mortality (hazard ratio 1.89, CI 1.1-3.2, p=0.020). No mortality difference between IP and IS was observed in those <75years of age. CONCLUSION AND RELEVANCE: Among adults with diabetes and SIHD aged ≥75years, IP therapy may be associated with increased mortality compared to IS therapy. Additional studies are needed to further refine optimal treatment strategies for diabetes and SIHD in old age.

Recruitment of underserved, high-risk participants to a head and neck cancer screening program.

OBJECTIVES/HYPOTHESIS: Early detection is essential in head and neck cancer treatment as prognosis varies greatly with stage at diagnosis. Underserved populations often present with advanced disease, and individuals with tobacco and heavy alcohol use demonstrate a higher head and neck cancer incidence. This study aims to evaluate whether various promotional methods differentially recruited behavioral risk factor positive and/or underserved populations to our screening event. STUDY DESIGN: Prospective cross-sectional study. METHODS: A hospital-based, medical student-run, free head and neck cancer screening event for 187 participants was held in April 2015. Medical campus-based, community-based, and media-based promotions were implemented to recruit participants. Event participants filled out questionnaires to determine how they were recruited, their risk-factor history, and their socioeconomic status. Prevalence of the higher-risk population across the various promotional methods was analyzed. RESULTS: Community-based promotions were significantly associated with the recruitment of participants in the underserved subgroups, namely uninsured (P = .019), unemployed (P = .006), and those with an annual household income <$20,000 (P < .001). Although not statistically significant, participants with behavioral risk factors reported a higher percentage of recruitment by media-based promotions. Campus-based promotions led to the highest absolute number, but not percentage, of higher-risk participants. CONCLUSIONS: Community-based promotions most efficiently recruit underserved guests to participate in a hospital-based head and neck cancer screening event as compared to media and campus-based promotions. Institutions interested in recruiting higher proportions of underserved guests to these screening events should consider focusing attention and allocation of resources to community-based promotions.
