Abstract
BACKGROUND Massive oropharyngeal bleeding post-chemoradiotherapy is a life-threatening condition that requires emergent management. METHODS This retrospective case series included 11 patients with oropharyngeal squamous cell carcinoma who suffered from massive bleeding during or following treatment with definitive chemoradiotherapy. Details of acute and definitive management of oropharyngeal bleeding are reported. RESULTS Nine of 11 hemorrhagic events occurred a mean (SD) of 88.6 days (53.6) after radiotherapy. Airway intubation and embolization were performed in 10 of 11 patients, followed by surgery in 7 of 11 patients. The most commonly embolized vessels were the external carotid and lingual arteries. At the time of discharge, 3 of 11 patients had a tracheostomy, and 7 of 11 continued to use a gastrostomy tube. Four patients died. CONCLUSIONS Hemorrhagic complications in oropharyngeal cancer treatment require emergent responses. Developing a workflow for coordination between multidisciplinary teams can maximize probability of survival and decrease morbidity.

Abstract
Background: The objective outcomes of masseteric nerve transfer in the setting of parotid malignancy are unclear. Objective: To measure objective facial reanimation outcomes of masseteric nerve transfer in patients with parotid malignancy who underwent parotidectomy with facial nerve resection. Materials and Methods: Retrospective review of patients who underwent masseteric nerve transfer for facial paralysis secondary to parotid malignancy was carried out at a tertiary referral hospital from August 2017 to November 2021. Objective facial reanimation outcomes were analyzed using Emotrics. Minimal follow-up of 6 months was required for inclusion. Results: Eight patients (five males) with a median age of 75.5 years (range 53-91) met inclusion criteria. Fifty percent had metastatic squamous cell carcinoma, and 50% had primary parotid malignancy. Five patients underwent concomitant cancer resection with facial nerve reconstruction. Seven patients received postoperative adjuvant radiotherapy. After reinnervation, patients had improved oral commissure excursion (from 1.51 mm ±1.27 to 3.77 mm ±1.81; p < 0.01) and facial symmetry during smile. Conclusion: In this study, masseteric nerve transfer enhanced oral commissure excursion and facial symmetry during smile in patients with parotid malignancy and facial nerve resection.

Abstract
OBJECTIVE To evaluate the effect of different virtual reality (VR) experiences on perioperative anxiety and pain among patients undergoing head and neck surgery. METHODS Prospective, randomized, comparative trial among patients undergoing outpatient head and neck surgery from December 2021 to April 2022 at a single academic institution. Group 1 utilized a preoperative VR gaming experience and a postoperative VR mindfulness experience, while Group 2 utilized the same interventions in the reverse order. Anxiety and pain were measured using visual analog scales (VAS). Primary outcomes were changes in post-intervention anxiety and pain. Secondary outcomes included vital sign changes and subjective patient experiences using a 5-point Likert scale. RESULTS There were 32 patients randomized for inclusion, with 16 patients per group. The majority of patients were female (65.6%) and mean (standard deviation) age was 47.3 (16.7) years. After outlier exclusion, there were no differences in post-intervention preoperative anxiety reduction (Group 1 vs. Group 2, median [IQR]: -12.0 [15] vs. -10.5 [13], p = 0.62). There were minor differences in vital sign changes (p < 0.05). Among the 10 patients in Group 1 and 12 patients in Group 2 who completed postoperative VR use, there were no differences in post-intervention pain reduction (-8.5 [22.3] vs. -7.5 [19.3], p = 0.95) or vital sign changes (p > 0.05). There were no differences in questionnaire responses, with high satisfaction in both groups (p > 0.05). No adverse events encountered. CONCLUSIONS Use of different VR experiences among patients undergoing outpatient head and neck surgery appears associated with similar reductions in perioperative anxiety and pain.

Abstract
Importance Transoral robot-assisted surgery (TORS) continues to have a major role in the treatment of oropharyngeal cancer. As new iterations of robotic technology are increasingly utilized, it is important to share learning experiences and clinical outcomes data, to optimize technical efficiency and clinical care. Observations This was a retrospective review of a large academic institution's initial clinical use of the da Vinci Single Port (SP) compared with the da Vinci Si (Si) system. A total of 205 TORS cases were reviewed: 109 in the SP group (November 22, 2018, through September 30, 2020), and 96 in the Si group (January 1, 2016, through November 12, 2018). Both groups had comparable operative times, rates of postoperative pharyngeal hemorrhage, length of hospital stay, and duration of nasogastric feeding tube use. There was no difference in pathological characteristics, rates of positive margins, or indications for or time to initiation of adjuvant therapy between the groups. The collective experience of 6 faculty members-who have trained 139 TORS surgeons for the SP system rollout-was compiled to provide a summary of learning experiences and technical notes on safe and efficient operation of the SP system. Conclusions and Relevance This Review found that the functional and oncologic outcomes were comparable between TORS cases performed with the Si and SP systems, and they had similar complication rates. Recognized advantages of the SP over the Si system include the availability of bipolar-energized instruments, a usable third surgical arm, and improved camera image quality.

Abstract
BACKGROUND To evaluate use of wearable activity devices to monitor trends in ambulation and sleep after head and neck surgery. METHODS Patients utilized Fitbit devices after surgery. Daily activity and sleep scores, step counts, and total sleep time (TST) were obtained. RESULTS There were 30 patients within the final cohort. Trends in step counts after specific procedures were identified, and higher subjective activity level correlated with step counts (r = 0.25, 95% CI = 0.07-0.41). Among patients with complete step data (n = 24), POD1 steps ≥200 were associated with reduced length of stay (4.5 ± 1.7 days vs. 7.2 ± 4.0 days, 95% CI = 0.33-5.0). Mean TST was 5.4 ± 2.5 h, TST correlated with subjective sleep scores (r = 0.25, 95% CI = 0.03-0.044), and clinical events associated with sleep-wake transitions on Fitbit devices were identified. CONCLUSIONS Wearable activity devices appear feasible for monitoring trends in postoperative ambulation and sleep. Use of these devices may facilitate postoperative recovery.

Abstract
Abstract
Purpose/Objectives: Tumor responses to cancer treatments are highly context-specific and often involve complex interactions between the anti-cancer therapy, genetically diverse tumor cells, and a heterogeneous tumor microenvironment (TME). All preclinical models fall short in capturing this complexity. CIVO (Comparative In Vivo Oncology) is an intratumoral microdose injection research tool intended to bridge the translational gap between preclinical and clinical studies by enabling in situ assessment of up to 8 oncology drugs or drug combinations simultaneously within a patient’s tumor. The CIVO Phase 0 model was established under FDA’s exploratory IND guidelines for microdosing. A Master Protocol was then developed, enabling ongoing evaluation of multiple investigational drugs and combinations without a need for stand-alone new protocols. Each investigational drug or combination is specified as a substudy of the Master Protocol, thus reducing administrative burden to clinical site staff and creating an infrastructure to ensure quality data and oversight of patient safety. This is a multi-center, open-label Phase 0 Master Protocol designed to study the localized pharmacodynamics (PD) of anti-cancer therapies within the TME when administered intratumorally in microdose quantities via the CIVO device. The safety of intratumoral microdose administration via the CIVO device will also be evaluated.
Materials/Methods: Approximately 12 subjects are expected to be enrolled per substudy. All substudies will evaluate subjects ≥18 years with a diagnosis of solid tumors with scheduled surgical intervention. Eligible subjects have at least one lesion (primary or recurrent tumor or effaced metastatic lymph node) ≥2 cm in the shortest diameter that is surface accessible for CIVO injection. Each substudy will define the tumor type and specific eligibility criteria for enrollment. The study visits consist of screening, CIVO injection, surgical intervention, and two follow-up visits. All patients will be injected by the CIVO device containing microdose quantities of drugs specified in respective substudies. The CIVO device can be configured with 3, 5, or 8 needles and the device configuration will be assigned on a per-patient basis, dependent upon lesion size. Following surgical resection, the injected portion of the tumor will undergo central PD biomarker analysis. At the time of submission, the study is open for enrollment with 1 substudy enrolling Head and Neck Squamous Cell Carcinoma (HNSCC) patients and 1 substudy enrolling HNSCC or soft tissue sarcoma patients. The Master Protocol was established to efficiently add substudies and accommodate evaluation of a wider repertoire of new agents in order to continually inform and de-risk drug development via the CIVO platform.

Abstract
Abstract
Purpose/Objectives: The human tumor microenvironment (TME) has a dramatic impact on cancer prognosis and therapeutic response, but accurate models of the native TME do not exist. The Comparative In Vivo Oncology (CIVO) platform was developed as a means to assess the effect of investigational agents on the native TME in a Phase 0 microdosing study. CIVO was clinically validated using approved agents and is used for the first time here to assess the impact of an investigational agent - the SUMOylation inhibitor TAK-981 - on the native human TME in HNSCC.
Materials/Methods: Eligible subjects have a confirmed HNSCC diagnosis, ECOG 0-2, and planned surgical resection. Injectable tumors were at the primary site or within cervical lymph nodes but had to be surface-accessible and ≥ 2cm. TAK-981 or control microdoses were simultaneously administered via a CIVO device and co-injected with a fluorescent tracking marker for injection site identification and visualization. Tumors were resected 24 or 72 hours after injection, processed, and then analyzed at a central site. Multiplexed biomarker staining and molecular profiling via GeoMx Digital Spatial Profiling were performed to capture pharmacodynamic responses in the native TME.
Results: As of January 2022, 8 subjects provided informed consent and were enrolled, and no adverse events associated with the injection procedure or microdoses have been reported. Biomarker analysis demonstrated TAK-981 distribution around the injection site accompanied by reduction of SUMOylation. Dose-dependent elevation of IFN1 signaling was also observed in TAK-981-exposed areas within the TME. Elevated IFN1 signaling was accompanied by TME reconfiguration, with increased macrophage M1 polarization and activation of dendritic cells, NK cells, and CD8+ T cells. TAK-981 exposure was also associated with upregulation of CXCL10, PD-L1, and an IFNγ gene expression signature predictive of response to immune checkpoint blockade.
Conclusion: IT microdosing with CIVO provided early insights into complex functional responses induced by the investigational agent TAK-981 that can only be accurately evaluated in the intact, native TME of a patient’s tumor. SUMO pathway inhibition in HNSCC tumors following TAK-981 exposure led to functional activation of multiple immune cell types, effectively shifting the local TME toward an inflamed “hot” state, highlighting TAK-981’s potential as an immune stimulating agent for treating patients with solid tumors. These data were generated while TAK-981 was still in Phase I dose escalation trials (via IV administration), highlighting CIVO’s ability to safely study investigational agents. Further evaluation of TAK-981 alone and in combination with other agents is ongoing in this Phase 0 CIVO microdosing trial.

Abstract
Importance Optimal postoperative pain management is challenging. Virtual reality (VR) provides immersive, 3-dimensional experiences that may improve pain control and reduce reliance on pharmacologic pain management. Objective To evaluate use of VR on postoperative pain management after head and neck surgery. Design, Setting, and Participants This prospective, pilot randomized clinical trial was conducted at Oregon Health & Science University from July 2020 to October 2021 and included patients hospitalized after major head and neck surgery. Interventions Similar 15-minute interactive gaming experiences (Angry Birds) using an Oculus Quest VR headset (VR intervention) or a handheld smartphone device (control). Main Outcomes and Measures The primary outcome was postintervention pain reduction. Pain scores were obtained preintervention, immediately after intervention, and then hourly for 4 hours. Secondary outcomes included changes in opioid use, measured as milligram morphine equivalents (MMEs), and patient experiences with their intervention using 5-point Likert scales. Results Of the 30 patients randomized for inclusion, the final population included 14 patients in the VR cohort and 15 patients in the control cohort; the majority of patients were male (26 of 29 [90%]), and the mean (SD) age was 58.3 (13.8) years. After outlier removal, there were clinically meaningful reductions in postintervention pain among patients in the VR group immediately after intervention (mean difference, -1.42; 95% CI, -2.15 to -0.70; d = 1.50), at 1 hour (mean difference, -0.86; 95% CI, -1.90 to 0.14; d = 0.67), 2 hours (mean difference, -1.07; 95% CI, -2.30 to 0.14; d = 0.69), and 3 hours (mean difference, -1.36; 95% CI, -2.80 to 0.13; d = 0.71) compared with patients in the control group. Patients in the VR group also demonstrated reductions in 4-hour postintervention opioid use compared with 4-hour preintervention opioid use (mean difference, -9.10 MME; 95% CI, -15.00 to -1.27 MME; d = 0.90) and 8-hour postintervention opioid use compared with 8-hour preintervention opioid use (mean difference, -14.00 MME; 95% CI, -25.60 to -2.40 MME; d = 0.94). There were no meaningful differences in subjective patient experiences with their respective interventions. Conclusions and Relevance In this randomized clinical trial, VR reduced pain scores and opioid use compared with a control intervention. Virtual reality may be a useful adjunct for postoperative pain management after head and neck surgery. Trial Registration ClinicalTrials.gov Identifier: NCT04464304.

Abstract
A sensitivity- and resolution-improving method for a low-frequency micro-vibration accelerometer is presented in this paper. A sensitivity model of the measurement system is derived and established. The key parameters that limit the sensitivity and the resolution of the accelerometer were identified through the sensitivity coefficient analysis method. The structural parameters and the signal process method were then optimized. Experimental results show that the sensitivity of the accelerometer has improved from 1.10 V/(m/s2) to 19.21 V/(m/s2), and the resolution has improved from 1.47 mm/s2 to 0.21 mm/s2. The lowest working frequency range has expanded from 1 Hz to 0.7 Hz. The presented method is effective and cheap and can be applied to other sensors.

Abstract
BACKGROUND The incidence of oral tongue squamous cell carcinoma (OTSCC) is increasing among younger birth cohorts. The etiology of early-onset OTSCC (diagnosed before the age of 50 years) and cancer driver genes remain largely unknown. METHODS The Sequencing Consortium of Oral Tongue Cancer was established through the pooling of somatic mutation data of oral tongue cancer specimens (n = 227 [107 early-onset cases]) from 7 studies and The Cancer Genome Atlas. Somatic mutations at microsatellite loci and Catalog of Somatic Mutations in Cancer mutation signatures were identified. Cancer driver genes were identified with the MutSigCV and WITER algorithms. Mutation comparisons between early- and typical-onset OTSCC were evaluated via linear regression with adjustments for patient-related factors. RESULTS Two novel driver genes (ATXN1 and CDC42EP1) and 5 previously reported driver genes (TP53, CDKN2A, CASP8, NOTCH1, and FAT1) were identified. Six recurrent mutations were identified, with 4 occurring in TP53. Early-onset OTSCC had significantly fewer nonsilent mutations even after adjustments for tobacco use. No associations of microsatellite locus mutations and mutation signatures with the age of OTSCC onset were observed. CONCLUSIONS This international, multicenter consortium is the largest study to characterize the somatic mutational landscape of OTSCC and the first to suggest differences by age of onset. This study validates multiple previously identified OTSCC driver genes and proposes 2 novel cancer driver genes. In analyses by age, early-onset OTSCC had a significantly smaller somatic mutational burden that was not explained by differences in tobacco use. LAY SUMMARY This study identifies 7 specific areas in the human genetic code that could be responsible for promoting the development of tongue cancer. Tongue cancer in young patients (under the age of 50 years) has fewer overall changes to the genetic code in comparison with tongue cancer in older patients, but the authors do not think that this is due to differences in smoking rates between the 2 groups. The cause of increasing cases of tongue cancer in young patients remains unclear.

Abstract
Objective: To establish the nutrition literacy core items for Chinese lactating women. Methods: The framework system and preliminary items of nutrition literacy were established through literature review and experts consultation. E-Delphi method was used to determine the nutrition literacy items. 11 experts in the field of maternal and child nutrition, obstetrics and gynecology, health education and nutrition and diseases were invited to score the importance of each nutrition literacy item via Email. The judgment basis and familiarity of experts towards the items, active coefficient, authority coefficient and harmony coefficient were evaluated and analyzed to generate the final list of nutrition literacy items. Results: The active coefficients of consultation in two rounds were 81.8% (9/11) and 87.5% (8/9). The authority coefficients were (0.86±0.11) and (0.85±0.06). The average scores of importance were (4.03±1.24) and (4.64±0.50)and the harmony coefficients were 0.556 (χ²=163.42, P<0.001) and 0.40 (χ²=64.41, P<0.001). After the second round of consultation, all selected items met the inclusion criteria. We identified the final list of nutrition literacy items consisting of 3 scales (basic knowledge and concept, lifestyles and dietary behaviors, and basic skills), 10 subscales (basic nutrition concept, food and nutrition knowledge, feeding knowledge, lifestyles, dietary behaviors, feeding behaviors, weight management, complementary food production, acquisition, understanding and application of nutrition information, judgement of nutrition information, and nutrition decision making) with 24 items in total. Conclusions: The framework system and core items of nutrition literacy were established for Chinese lactating women based on E-Delphi method. The experts involved in the consultation process presented a performance with good representativeness, enthusiasm and authority. All experts' opinions are coordinated and unified, which could satisfy the demand of developing nutrition literacy core items for target population.

Abstract
Objective: To explore the pathogenic variants of a family with syndromic deafness by high-throughput sequencing. Methods: The family was from Puyang City, Henan Province, and had four members, including two with syndromic deafness. The proband and his sister had congenital deafness, and their parents had normal phenotypes. The clinical phenotype of the family was characterized using clinical examinations and pedigree analysis. The clinical examinations included imaging examination, audiometry (pure tone audiometry, acoustic immittance, brainstem auditory evoked potential, and otoacoustic emission), vestibular function test, and ophthalmic examination (visual acuity test, visual field test, fundus examination, visual evoked potential, and electroretinogram). Target exome sequencing of 129 known deafness genes and bioinformatics analysis were used to screen suspected pathogenic variants. Sanger sequencing and minigene assay were used to verify and functionally investigate the mutation detected, respectively. According to the standards and guidelines for interpreting genetic variants proposed by the American College of Medical Genetics and Genomics, the variants c.6049G>A and c.8699A>G were classified as pathogenic/likely pathogenic, and the variant c.9856C>G was classified as variants of uncertain significance. Results: The probands and his sister had severe sensorineural hearing loss with decreased binocular vision, night blindness, decreased peripheral visual field sensitivity and partial visual field defect, and normal vestibular function. Both of them had three CDH23 mutations, including CDH23 (NM_022124.5) c.6049G>A (p.Gly2017Ser),c.9856C>G (p.His3286Asp), and c.8699A>G (p. Asp2900Gly), The first two were inherited from the father, and the last one was from the mother. The missense variants c.9856C>G and c.8699A>G were not included in the gnomad database. The missense mutation c.6049G>A was located in the last position of exon 46 and was predicted to affect splicing by bioinformatics software. The minigene experiment showed that the mutation cause exon skipping of exon 46, resulting in an abnormal protein. Conclusions: Compound heterozygous variations of the CDH23 are the leading cause of USH1D in the family. This study confirms that the compound heterozygosity of splicing and missense variants of the CDH23 gene could lead to USH1D.

Abstract
Objective: To analyze the effects of HIV non-occupational post-exposure prophylaxis (nPEP) in men who have sex with men (MSM) in Nanning and Liuzhou, Guangxi Zhuang Autonomous Region. Methods: Participants were recruited through community publicity and advocacy under a "Trinity" approach among non-governmental organizations (NGO), CDCs/hospitals and pharmacies. Basic information, drug taking and follow-up tests of participants who had enrolled for 28 days of the research were collected. Descriptive statistics were used for data analysis. Results: From September 2017 to March 2019, a total of 213 MSM cases consulted for nPEP service, 159 of them were eligible for nPEP, and 154 were enrolled in the study for drug taking. For 132 cases enrolled in the study for 28 days and above, 118 completed the 28-day course of antiretroviral therapy (ART), while 10 failed to complete the 28-day course of ART, and 4 could not be confirmed whether completed the full course of ART due to loss of contact. For those who completed 28-day course of ART, 94.1% (111/118) and 75.4% (89/118) respectively received HIV tests at 4-6 weeks and 3 months after exposure, the results were all HIV negative. Conclusion: Under the "Trinity" approach, taking antiviral drugs earlier after HIV non-occupational exposure can effectively reduce the risk of HIV infection and to some extent, reduce the new infection cases.

Abstract
INTRODUCTION Head and Neck Cancer Awareness and Screening Programs (HNCASP) are popular community outreach events hosted by academic and community otolaryngology departments. However, long-term follow-up of participants is lacking. PATIENTS AND METHODS Participants of a HNCASP held at an academic cancer center prospectively filled out demographic and risk factor surveys followed by HNC screening examination. A phone interview was conducted for participants between 2012 and 2016 with suspicious findings to assess outcomes. RESULTS Participants were largely Caucasian, female, and had health insurance, reflecting the setting at an academic medical center. Despite this, there were 156 (16.8%) positive screenings; 47 of these completed follow up interviews. Twelve (1.1% of all participants) cancer cases were confirmed. DISCUSSION A significant proportion of HNCASP participants benefited from this screening opportunity. Education regarding HNC is the primary benefit and motivational factor for attendance of HNCASPs, although a significant subset of patients was identified that needed follow-up, and several cancers were detected.

Abstract
Previous studies have shown that lncRNAs play crucial roles in cerebral ischemia/reperfusion injury. In this study, the function and possible mechanism of lncRNA HCP5 in cerebral ischemia/reperfusion injury was investigated. An oxygen glucose deprivation (OGD) model in N2a cells was used to simulate cerebral ischemia/reperfusion injury in vitro. The functional mechanism of lncRNA HCP5 was detected using Trypan blue staining, JC-1, MTT and dual luciferase reporter assays. The expression of apoptosis-related proteins (Bcl-2 and Bax) was measured by Western blot analysis. We found that lncRNA HCP5 was upregulated in N2a cells treated with OGD/R, and knockdown of lncRNA HCP5 enhanced cell viability and reduced cell death. In addition, miR-652-3p was found to act as a sponge for lncRNA HCP5. The overexpression of miR- 652-3p can prevent cerebral ischemic reperfusion injury, however, lncRNA HCP5 attenuated the protective effect of miR-652-3p in cerebral ischemic reperfusion injury. In conclusion, upregulation of lncRNA HCP5 may exacerbate cerebral ischemic reperfusion injury by sponging miR-652-3p.

Abstract
In this paper, we propose a new touch-trigger probe with high precision and a large permissible measurement range. A wedge prism was used in the sensing unit to achieve 3D detection using only one optoelectronic sensor. The measurement range was expanded from ±8 µm to ±14 µm through the new optical structure. The probe has uniform stiffness and uniform sensitivity. Some experiments were performed to investigate the performance of the probe. It was found that the probe has a resolution of 10 nm and a repeatability of less than 9.1 nm. The applicability of the probe was also verified.

Abstract
Electronic cigarettes (e-cigarettes) are a popular method to help quit tobacco smoking. However, there is a paucity of data in the literature on their safety and efficacy. Recently, the Indian Government has called for a ban on all e-cigarettes and taken steps to restrict access to vaping products from the market. This major decision was an attempt to safeguard the younger population from using e-cigarette and their possible longer-term addiction together with its promotions by domestic industries. In this article, we evaluate the role of e-cigarettes to help stop smoking tobacco cessation and consider the factors that have facilitated the ban on e-cigarettes in India.

Abstract
Sigma-1 receptor (Sig-1R) is a ligand-operated protein that modulates activity of various proteins. It is expressed within the endoplasmic reticulum membranes of multiple organs. We examined the role of Sig-1R in hepatic ischemia-reperfusion injury (IRI). We studied IRI indicators in Sig-1R-/- mice and compared them with wild-type controls. In addition, we assessed the influence of Sig-1R agonist, fluvoxamine, on IRI in both types of animals. We found that Sig-1R-/- mice exhibited significantly decreased liver damage after hepatic IRI as compared to wild-type mice. This effect was manifested by decreased serum levels of alanine aminotransferase (AST), aspartate aminotransferase (ALT), myeloperoxidase (MPO), and supernatant level of lactate dehydrogenase (LDH), decreased endothelial glycocalyx shedding indexed by decreased serum levels of heparan sulfate and syndecan-1, slightly improved liver histology and reduced metalloproteinase-9 expression. Furthermore, in comparison to Sig-1R-/- mice, fluvoxamine significantly increased serum levels of AST, ALT, MPO, and LDH in wildtype animals in a dose-dependent manner at 6 h after IRI. Our findings demonstrate that the absence of Sig-1R provides a protective effect during hepatic IRI. Sig-1R-mediated signaling pathways may play distinct roles in IRI in different organs. The dynamic interaction between Sig-1R and other signaling molecules in different organs needs to be examined further.

Abstract
Importance The current opioid abuse epidemic in the United States requires evaluation of prescribing practices within all medical specialties. This examination includes a review of postoperative pain management for patients undergoing major head and neck procedures. Objective To report differences in postoperative pain regimens between an international and domestic head and neck surgical program. Design, Setting, and Participants Pain management patterns after head and neck surgery in the programs at Chinese University of Hong Kong (CUHK) and Oregon Health and Science University (OHSU) were compared with a focus on opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), acetaminophen or paracetamol, and anxiolytics. Cases from July 1, 2013, through August 31, 2017, were reviewed. Standing medication orders the day before surgery (PRE1), postoperative day 6 (POD6), and postoperative day 14 (POD14) were compared between institutions. Exposures Head and neck surgery. Results A total of 253 cases from CUHK and 567 cases from OHSU were analyzed (mean [SD] age, 59.4 [14.3] and 60.1 [16.4] years, respectively). Patients from OHSU had a significantly higher frequency of opioid orders on PRE1 (15.3% vs 1.6%; odds ratio [OR], 11.3; 95% CI, 4.09-31.10), POD6 (86.8% vs 0.4%; OR, 1653.12; 95% CI, 228.51-11 959.01), and POD14 (71.4% vs 0.8%; OR, 313.75; 95% CI, 77.12-1276.52). There were no significant differences in acetaminophen or paracetamol, NSAID, or anxiolytic orders between institutions. Institution was the most significant indicator for the presence of opioid orders on POD6 (OR, 4271.10; 95% CI, 380.04-47 999.70) and POD14 (OR, 330.35; 95% CI, 79.67-1369.82). In addition to treating institution, multivariate analysis showed that PRE1 opioid orders indicated a significant increase in likelihood of opioid orders on POD6 (OR, 4.77; 95% CI, 1.23-18.57) but not POD14. POD6 anxiolytic orders remained a significant indicator of opioid orders for POD6 (95% CI, 1.49-113.10) and POD14 (95% CI, 1.17-5.03), respectively. Conclusions and Relevance A significantly lower frequency of postoperative opioid orders was observed from CUHK compared with OHSU across similar major head and neck procedures. This contrast encourages a careful examination of (1) cultural and patient expectations of pain control, (2) the metrics by which control is assessed, (3) industry and economic drivers of opioid use, and (4) alternatives to opioid pain regimens. A thoughtful shift in postoperative pain protocols that deemphasizes opioid use may be an opportunity to counter the epidemic of opioid abuse in the United States.

Abstract
Importance Severe anterior septal deviation and resultant nasal obstruction represent a difficult surgical task to correct. The goal of surgery is to straighten the anterior dorsal and caudal struts, while maintaining nasal tip and midvault support. This study presents a novel extracorporeal septoplasty technique to straighten the crooked anterior septum. Objective To describe the novel anterior septal transplant technique, which consists of complete resection of the caudal septum and reconstruction with extended spreader grafts and a columellar strut, without a separate caudal septal replacement graft. Design, Setting, and Participants This study was a retrospective case series at a tertiary academic referral center. Participants were sequential adult patients undergoing anterior septal transplant from January 1, 2008, to December 31, 2015. Main Outcomes and Measures Patient-reported nasal obstruction using Nasal Obstruction Symptom Evaluation (NOSE) scores and objective photographic analysis. Nasal tip deviation, projection, and rotation were measured. Preoperative and postoperative outcomes were compared. Complications are reported. Results Seventy-one patients (mean age, 46 years [age range, 16-72 years]; 48 [67.6%] female and 23 [32.4%] male) were included in the case series. Postoperative NOSE scores (mean [SD], 24.00 [24.58]) were significantly better than preoperative NOSE scores (mean [SD], 72.25 [14.55]) (P < .001). A separate cohort of 32 patients (mean age, 42 years [age range, 13-72 years]; 23 [71.9%] female and 9 [28.1%] male) had photographs available for analysis. In the frontal view, nasal deviation improved from a mean (SD) of 2.9 (2.0) degrees before surgery to a mean (SD) of 1.4 (1.7) degrees after surgery (P = .004). In the base view, the deviation was corrected from a mean (SD) of 4.9 (2.8) degrees to a mean (SD) of 1.7 (1.2) degrees (P < .001). Tip rotation and projection were unchanged after surgery. Four patients had mild dorsal irregularities after surgery. Conclusions and Relevance Anterior septal transplant by the described technique is a safe and effective treatment option for severe anterior septal deviation. Level of Evidence 4.

Abstract
OBJECTIVE To demonstrate the safety and compatibility of microvascular couplers in patients undergoing postoperative magnetic resonance imaging (MRI) scans. STUDY DESIGN Retrospective case series. METHODS A consecutive review of 1,252 patients undergoing free tissue transfer for head and neck reconstruction at Oregon Health and Sciences University (OHSU) between 2010 and 2017 who had microvascular coupler Synovis, Baxter Deerfield, IL (Synovis Life Technologies, Saint Paul, MN) implantation were reviewed. One hundred fifteen patients had a subsequent MRI scan, which consisted of a variety of Phillips (Amsterdam, Netherlands) MRI machines ranging from 1.0 to 3.0 Tesla (T) in magnetic strength. RESULTS These 115 patients underwent 121 free flaps with 131 couplers (including 32 flow couplers) utilized for venous anastomoses. Couplers ranged in size from 1.5 to 4.0 mm (3.0 mm [42%] followed by 3.5 mm [21%], 2.5 mm [19%], 2.0 mm [10%], 4.0 mm [6%], and 1.5 mm [2%]. Three hundred fifty-nine MRI scans (2 days to 91 months postoperatively) were obtained with 233 MRIs for cancer surveillance, and the remaining were obtained for neurologic disease, injury, or evaluation for metastases. No complications occurred related to the MRI and the metallic components of the coupler or other metal implants, such as reconstruction bars, vascular clips, or metallic surgical mesh. Additionally, no radiology report commented on MRI distortion due to the coupler placement, which contrasts the distortion seen with the other metallic implants. CONCLUSION Microvascular couplers and their constitutive stainless-steel pins have not been found to cause any complications in a large series of consecutive patients undergoing multiple MRIs with magnetic strength up to 3 T. The U.S. Food and Drug Administration advocates medical alert notification for patients with couplers; however, hesitation regarding potential MRI scanning for surveillance or otherwise is unwarranted. LEVEL OF EVIDENCE 4 Laryngoscope, 130:1428-1430, 2020.

Abstract
Objective: To investigate the normal urinary manganese value in healthy adults in Guangxi, China and its distribution characteristics. Methods: From 2015 to 2016, stratified random sampling based on age and sex was performed to select 1533 healthy adults aged 18-60 years in Nanning,Liuzhou,Guilin,Hezhou,Wuzhou,Yulin,Guigang,Beihai,Qinzhou,Laibin,Hechi Nandan,Bose Jingxi,Chongzuo Daxin,and Fangchenggang.All of them had no history of occupational manganese exposure or acute or chronic liver/renal diseases and had lived in the local area for more than one year. A total of 1417 urine samples with normal specific gravity and complete data were obtained, and graphite furnace atomic absorption spectrometry was used to measure urinary manganese.The distribution characteristics of urinary manganese level were analyzed among adults with different ages,sexes,or presence or absence of smoking habits or among those who lived or did not live in the mining area. Results: The geometric mean of urinary manganese among healthy adults in Guangxi was 0.52 μg/L,and the upper limit of normal was 5.68μg/L. There was no significant difference in urinary manganese level between the healthy adults with different ages, sexes,or presence or absence of smoking habits (P>0.05).The healthy adults who lived in the mining area of nonferrous metal mines had a significantly higher geometric mean of urinary manganese than those who did not live in such areas(1.65μg/Lvs0.34μg/L,P<0.01). Conclusion: The upper limit of normal of urinary manganese is 5.68 μg/L among healthy adults in Guangxi,and the healthy adults who live in the mining area of manganese mine or nonferrous metal mines have a significantly higher urinary manganese level than those who do not live in such areas.

Abstract
Corticosteroid is commonly used for the clinical treatment of pain. It is safe, reliable and a simple procedure with other advantages. However, a possible potential catastrophic complication of corticosteroid injections in distal limbs (e.g., the wrist) is acute radial artery ischemia due to the injection into the radial artery. This may result from spasm attributed to the steroids. While the complication of corticosteroids in the wrist is rare, ischemia of the hand caused by corticosteroid injections in radial artery has been reported in several articles. We treated five patients with microcirculation disturbance of distal limb caused by corticosteroid treatment. Here, we report the two different treatment strategies adopted according to the severity of the disease which achieved good therapeutic effects.

Abstract
OBJECTIVES Notch signaling is frequently altered in head and neck squamous cell carcinoma (HNSCC). However, the nature and clinical implications of this dysregulation are not well understood. We previously described an association of transcriptionally active NOTCH1 Intracellular Domain (NICD1) immunohistochemical (IHC) expression pattern with high-risk pathologic characteristics. Here we further characterize Notch signaling in HNSCC. MATERIALS AND METHODS IHC expression patterns and clinicopathologic associations of Notch pathway molecules were evaluated among 78 tumors with known NOTCH1 mutation status. IHC was performed for JAG1, a NOTCH1 activating ligand, and HEY1, an NICD1 transcriptional target and Notch pathway activation marker. IHC pattern and H-score (% staining × intensity) were recorded and compared to clinicopathologic characteristics and survival. Survival was analyzed using Kaplan Meier method and Cox proportional hazards models (HR). RESULTS JAG1 and NICD1 expression patterns were highly concordant among tumors without truncating NOTCH1 mutations (p < 0.001), but were dissimilar among tumors with truncating NOTCH1 mutations (p = 0.24). There was evidence for JAG1-independent NOTCH1 activation among seven tumors, all with wild-type NOTCH1. HEY1 expression was associated with neither JAG1 nor NICD1 expression, but was associated with NOTCH1 mutation status (p = 0.03). Twelve (16%) tumors expressed HEY1 but not NICD1. Higher HEY1 H-score was significantly associated with worse overall (adjusted hazard ratio [aHR] 2.0, 95% CI = 1.0-4.2) and disease-specific (aHR = 3.3, 95% CI = 1.4-7.9) survival, whereas JAG1 and NICD1 expression were not associated with survival. CONCLUSIONS These findings suggest both NOTCH1-dependent and -independent HEY1 regulation, and imply a previously unrecognized prognostic role for HEY1 in HNSCC.

Abstract
OBJECTIVE To perform unilateral patellar resurfacing and contralateral patellar retention in bilateral total knee arthroplasty (TKA) randomly, and to compare the clinical effects of patellar retention with patellar resurfacing in TKA. METHODS In the study, 14 bilateral knee osteoarthritis (OA) patients were randomized in the bilateral TKA to receive unilateral patellar resurfacing and contralateral patellar retention, including 28 knees, all were females, 53 to 78 years old, with average (66.9±7.8) years, and the BMI was (26.3±1.8) kg/m2. All subjects were followed up from 3 to 12 months. The clinical effects were evaluated based on measurements of American Knee Society score (KSS), range of motion (ROM), anterior knee pain, patellar clunk, and patellar tilt angle (PTA). RESULTS All the wounds healed primarily without significant complications, such as infection, aseptic loosening, patellar fracture and so on. The preoperative KSS scores of patellar resurfacing group were 38.9±22.2, and the scores changed to be 92.4±6.7 after operation, which were added by 53.5±20.3. While in the patellar retention group, the KSS scores were 38.4 ± 20.5 preoperatively, and after operation, which were added to be 92.1±4.2, and improved by 53.7±21.4. The differences in the changed KSS scores between TKA with and without patellar resurfacing were not statistically significant (Independent t-test, P=0.98). The ROM was changed from 95.4°±13.5° preoperatively to 120.4°±8.9° postoperatively in the patellar resurfacing group and from 92.9°±19.1° preoperatively to 120.4±8.4° postoperatively in the patellar retention group. The ROM of the two group were increased by 25.0°±14.5° and 27.5°±19.4° respectively. However, no remarkable differences were observed between the 2 groups in the knee ROM (Independent t-test, P=0.70). At the end of the latest follow-up, 3 knees in the patellar resurfacing group and 2 knees in the patellar retention group had knee anterior pain, the incidences of anterior knee pain were 21.4% and 14.3% respectively. There was no obvious difference for the incidence of post-operative anterior knee pain (Chi-square test, P=0.62). The incidences of post-operative patellar clunk in the 2 groups were all with 3 knees (21.4%), which had no significant difference in the 2 groups (Chi-square test, P=1.00). The post-operative PTA were 2.6°±2.6° in the patellar resurfacing group and 3.6°±2.9° in the patellar retention group, respectively. There was also no statistical difference between the 2 groups (Chi-square test, P=0.36). CONCLUSION For knee OA patients with mild or moderate patellar cartilage damage, performing patellar resurfacing or not didn't significantly affect anterior knee pain, patellar clunk, functional outcomes or patellar tracking after TKA. So we suggest retain patella in TKA for OA patients with mild or moderate patellar cartilage damage.

Abstract
BACKGROUND The osteocutaneous radial forearm free flap (RFFF) is a versatile flap primarily used to reconstruct composite defects involving the mandible. The purpose of this study was to describe our experience with this flap for nonmandible reconstruction. METHODS All patients undergoing nonmandible osseous reconstruction with free-tissue transfer were reviewed. Patients with osteocutaneous RFFF reconstructions were evaluated. The retrospective review of all osteocutaneous RFFFs was performed from 1998 to 2014. RESULTS One hundred forty-two nonmandible osseous reconstructions were performed. Twenty-five patients underwent nonmandible osteocutaneous RFFF reconstruction. Eleven patients failed previous nonmicrovascular reconstruction. Reconstruction was for defects of the: palatomaxillary complex (n = 15), orbitomaxillary complex (n = 4), nasomaxillary complex (n = 4), larynx (n = 1), and clavicle (n = 1). There were no flap compromises. Postoperative complications included: 2 partial intraoral dehiscences; 1 recipient-site infection; and 1 seroma. Eight reconstructions required secondary procedures to improve functional and/or cosmetic outcomes. CONCLUSION The osteocutaneous RFFF is a robust flap that can be used to reconstruct composite defects involving bone and soft-tissue beyond the mandible.

Abstract
Carpal tunnel syndrome (CTS) is a medical condition due to compression of the median nerve as it travels through the wrist at the carpal tunnel. Few studies have been carried out to examine the effectiveness of mini-open technique for carpal tunnel release using minor wrist skin crease incision in patients with mild CTS. Therefore, the present study was designed to improve the neurophysiological parameters for the diagnosis of mild CTS, and to examine the effectiveness of small incision surgery for the clinical treatment of mild CTS. To this end, we applied the electrophysiological diagnosis of difference between median and ulnar palmar latencies (PMPU) and the difference of median and ulnar latencies from D4 stimulation (D4MD4U) in 80 patients with mild CTS, whom were diagnosed by hand surgeon at the First Hospital of Jilin University. Those patients showed normal in median nerve electrophysiological examination, and received minor wrist skin crease incision surgery. All patients were followed up and received electromyography (EMG) examination. We showed that D4MD4U and PMPU methods are sensitive diagnosis methods for mild CTS, and mini-open wrist crease incision is beneficial for the treatment of mild CTS in clinical settings.

Abstract
Peritrophic membrane proteins are important components of the insect peritrophic membrane. A novel cDNA gene encoding a chitin-binding protein, named secbp66, was identified by immunization screening of the cDNA library of Spodoptera exigua. The full length of secbp66 is 1806 bp, which encodes 602 amino acids. The predicted weight of the protein is 64.2 kDa. Bioinformatic analysis showed that a signal peptide composed of 17 amino acids located at the N-terminal of SeCBP66 contained seven tandem putative Type-II functional chitin-binding domains and five potential N-glycosylation sites, but no O-linked glycosylation sites. To study the properties of SeCBP66, recombinant SeCBP66 was successfully expressed in the insect cell line BTI-Tn-5B1-4 with a Bac-to-Bac expression system. A chitin binding experiment showed that the recombinant SeCBP66 protein could bind to chitin strongly. This study of the novel chitin-binding protein SeCBP66 provides a basis for developing new control targets for S. exigua.

Abstract
We did a case-control study to provide a more comprehensive evaluation of the association of the pre-miR-196a2 rs11614913 polymorphism with gastric cancer. Between January 2013 and December 2014, 182 patients newly diagnosed with primary gastric cancer and 182 control subjects were recruited at Zhengzhou People's Hospital. For SNP genotyping, we used the Assay Designer 3.1 to design the primers of polymerase chain reaction. Using the chi-square test, we found that patients with gastric cancer were more likely to be alcohol drinkers (χ(2) = 4.4, P = 0.04), to have a family history of cancer in the first relatives (χ(2) = 5.29, P = 0.02), and to be infected with Helicobacter pylori (χ(2) = 23.39, P < 0.001). A significant difference in the genotype distributions of rs11614913 was observed in our study (χ(2) = 6.66, P = 0.04). By logistic regression analysis, we found that the CC genotype of rs11614913 was associated with an increased risk of gastric cancer in a codominant model (OR = 2.68, 95%CI = 1.17-6.44). By stratification analysis, we found that the CC genotype was associated with a strongly increased risk of gastric cancer in drinkers when compared with the TT+TC genotype (OR = 5.63, 95%CI = 1.54-30.76). In conclusion, the results of our study suggest an association between the rs11614913 gene polymorphism and an elevated risk of gastric cancer, especially in drinkers.

Abstract
We conducted a hospital-based case-control study to investigate the association between 3 common SNPs in the ERCC5 gene (rs1047768, rs751402, and rs17655) and the risk of developing gastric cancer. Between January 2013 and December 2014, samples were collected from 216 gastric cancer patients and 216 control subjects. ERCC5 rs1047768, rs751402, and rs17655 polymorphisms were genotyped by polymerase chain reaction combined with restriction fragment length polymorphism analysis. By conditional logistic regression analysis, the GG genotype of rs17655 was found to be associated with an elevated risk of gastric cancer in a codominant model, and the adjusted OR (95%CI) was 1.96 (1.10-3.50). Moreover, in a dominant model, the CG + GG genotype of rs17655 was correlated with an increased risk of gastric cancer compared to the CC genotype (OR = 1.48; 95%CI = 1.00-2.22). rs1047768 and rs751402 were not significantly correlated with an increased or decreased gastric cancer risk.

Abstract
As the electrical source of hearts, sino-atrial node cells (SANCs) play significant roles in rhythmic firings. Due to the complex structure and function of SANCs, electrical interactions of SAN and its surrounding atrium has not yet been fully understood. The aim of the present study is to investigate effects of coupling conductance between SAN and atrial cells as well as the ectopic beats in atrium on automaticity of the SAN by computer simulation methods. On the basis of a dynamic mathematical single cell model considering the heterogeneity of central and peripheral SANCs, a two-dimensional inhomogeneous tissue slice including SAN and atrium was developed. The operator splitting method was used to integrate the tissue model. The results demonstrated that the coupling conductance between SAN and atrium had effects on the direction of spontaneous action potential conduction in SAN. Weak coupling resulted in a shift of the earliest pacemaker site from central to peripheral SANCs. Additionally, the ectopic beat-induced excitation in atrium was found to be able to enter into and overdrive suppress the automaticity of SAN. Even if the ectopic beat was delivered after the spontaneous firing had started in central SANCs, the spontaneous conduction toward the periphery could also be suppressed by the retrograde activation from the entering atrial depolarization wave. These findings suggested a direct link between sinus node dysfunction and atrial arrhythmias, and therefore were helpful in explaining the role of atrium in sinus node dysfunction.

Abstract
Traditional open surgical approaches are indicated for treatment of select tumor subsites of head and neck cancer, but can also result in major cosmetic and functional morbidity. Transoral surgical approaches have been used for head and neck cancer since the 1960s, with their application continuing to evolve with the changing landscape of this disease and recent innovations in surgical instrumentation. The potential to further reduce treatment morbidity with transoral surgery, while optimizing oncologic outcomes, continues to be investigated. This review examines current literature evaluating oncologic and quality-of-life outcomes achieved through transoral head and neck surgery.

Abstract
Objective Pharyngocutaneous fistula is a common complication in laryngectomy patients, particularly in previously irradiated cases. We initiated a comprehensive performance improvement intervention in all head and neck surgery patients intended to reduce postoperative infection and fistulae rates. We report our review of outcomes within laryngectomy patients. Study Design Case series with chart review. Setting Academic tertiary referral center. Subjects Nineteen laryngectomy patients at risk of postoperative fistula formation. Methods We reviewed the medical records of all patients who had undergone laryngectomy procedures between January 2013 and April 2014. Clinicodemographic data were obtained, including history of diabetes, prior radiation therapy, type of reconstruction performed for closure of the pharyngeal defect, and the presence or absence of postoperative fistula. Results The study population comprised 19 laryngectomy patients. Prior to implementation of our performance improvement intervention, 8 of 11 (73%) patients undergoing laryngectomy developed postoperative fistulae. After intervention, 0 of 8 patients developed fistulae ( P = .002). Prior radiation, diabetes mellitus, and overall stage were not associated with a reduction in fistula rate ( P > .05). Conclusion Comprehensive uniform application of a standard antibiotic prophylaxis, surgical technique, perioperative care, and treatment of comorbid conditions can significantly reduce and potentially eliminate fistulae in laryngectomy patients who are especially at risk.

Abstract
In this Letter, we theoretically propose for the first time that graphene monolayers can be used for superscatterer designs. We show that the scattering cross-section of the bare deep-subwavelength dielectric cylinder is markedly enhanced by six orders of magnitude due to the excitation of the first-order resonance of graphene plamons. By utilizing the tunability of the plasmonic resonance through tuning graphene's chemical potential, the graphene superscatterer works in a wide range of frequencies from several terahertz to tens of terahertz.

Abstract
The associations between single nucleotide polymorphisms (SNPs) in the displacement loop (D-loop) of mitochondrial DNA (mtDNA) and cancer risk and disease outcome have been extensively analyzed. We investigated the association between age-at-onset and SNPs in the mitochondrial D-loop using a population-based series of non-small cell lung cancer (NSCLC) patients. The D-loop region of mtDNA from NSCLC patients was amplified and sequenced. The age-at-onset curve of NSCLC patients was calculated using the Kaplan-Meier method at each SNP site and values were compared using the log-rank test. The SNP sites of nucleotides 200G/A and 16362T/C were identified to determine their association with age-at-onset of NSCLC using the log-rank test. The nucleotide 207G/A was identified for its association with age-at-onset at a borderline significance level (P = 0.060). We found that genetic polymorphisms in the D-loop were predictive markers for age-at-onset in NSCLC patients. Accordingly, the analysis of genetic polymorphisms in the mitochondrial D-loop can be used to identify NSCLC patient subgroups at high risk of early onset.

Abstract
The Notch pathway is frequently altered in head and neck squamous cell carcinomas (HNSCC); however, the clinical significance of NOTCH1 dysregulation is poorly understood. This study was designed to characterize expression of the transcriptionally active NOTCH1 intracellular domain (NICD1) in HNSCCs and evaluate its association with NOTCH1 mutation status and clinical parameters. IHC for NICD1 was performed on 79 previously sequenced archival HNSCCs with known NOTCH1 mutation status. Three distinct immunohistochemical staining patterns were identified: positive/peripheral (47%), positive/nonperipheral (34%), and negative (19%). NICD1 expression was associated with NOTCH1 mutation status (P < 0.001). Most NOTCH1-wild-type tumors were peripheral (55%), whereas mutated NOTCH1 tumors were most commonly negative (47%). Nonperipheral tumors were more likely than peripheral tumors to have extracapsular spread [adjusted odds ratio (aOR), 16.01; 95% confidence interval (CI), 1.92-133.46; P = 0.010] and poor differentiation (aOR, 5.27; 95% CI, 0.90-30.86; P = 0.066). Negative staining tumors tended to be poorly differentiated (aOR, 24.71; 95% CI, 1.53-399.33; P = 0.024) and were less likely to be human papillomavirus (HPV) positive (aOR, 0.043; 95% CI, 0.001-1.59; P = 0.087). NOTCH1 mutagenesis was significantly associated with HPV status, with NOTCH1-wild-type tumors more likely to be HPV positive than NOTCH1-mutated tumors (aOR, 19.06; 95% CI, 1.31-276.15; P = 0.031). TP53 disruptive mutations were not associated with NICD1 expression or NOTCH1 mutation. In conclusion, NICD1 is expressed in three distinct patterns in HNSCC that are significantly associated with high-risk features. These findings further support a dual role for NOTCH1 as both tumor suppressor and oncogene in HNSCC. Further research is necessary to clarify the role of NOTCH1 in HNSCC and understand the clinical and therapeutic implications therein.

Abstract
Development of head and neck squamous cell carcinoma (HNSCC) is characterized by accumulation of mutations in several oncogenes and tumor suppressor genes. We have formerly described the mutation pattern of HNSCC and described NOTCH signaling pathway alterations. Given the complexity of the HNSCC, here we extend the previous study to understand the overall HNSCC mutation context and to discover additional genetic alterations. We performed high depth targeted exon sequencing of 51 highly actionable cancer-related genes with a high frequency of mutation across many cancer types, including head and neck. DNA from primary tumor tissues and matched normal tissues was analyzed for 37 HNSCC patients. We identified 26 non-synonymous or stop-gained mutations targeting 11 of 51 selected genes. These genes were mutated in 17 out of 37 (46%) studied HNSCC patients. Smokers harbored 3.2-fold more mutations than non-smokers. Importantly, TP53 was mutated in 30%, NOTCH1 in 8% and FGFR3 in 5% of HNSCC. HPV negative patients harbored 4-fold more TP53 mutations than HPV positive patients. These data confirm prior reports of the HNSCC mutational profile. Additionally, we detected mutations in two new genes, CEBPA and FES, which have not been previously reported in HNSCC. These data extend the spectrum of HNSCC mutations and define novel mutation targets in HNSCC carcinogenesis, especially for smokers and HNSCC without HPV infection.

Abstract
Background Salivary gland adenoid cystic carcinoma (ACC) is a rare cancer, accounting for only 1% of all head and neck malignancies. ACC is well known for perineural invasion and distant metastasis, but its underlying molecular mechanisms of carcinogenesis are still unclear. Principal Findings Here, we show that a novel oncogenic candidate, suprabasin (SBSN), plays important roles in maintaining the anchorage-independent and anchorage-dependent cell proliferation in ACC by using SBSN shRNA stably transfected ACC cell line clones. SBSN is also important in maintaining the invasive/metastatic capability in ACC by Matrigel invasion assay. More interestingly, SBSN transcription is significantly upregulated by DNA demethylation induced by 5-aza-2′-deoxycytidine plus trichostatin A treatment and the DNA methylation levels of the SBSN CpG island located in the second intron were validated to be significantly hypomethylated in primary ACC samples versus normal salivary gland tissues. Conclusions/Significance Taken together, these results support SBSN as novel oncogene candidate in ACC, and the methylation changes could be a promising biomarker for ACC.

Abstract
Scientific innovation has enabled whole exome capture and massively parallel sequencing of cancer genomes. In head and neck cancer, next-generation sequencing has granted us further understanding of the mutational spectrum of squamous cell carcinoma. As a result of these new technologies, frequently occurring mutations were identified in NOTCH1, a gene that had not previously been implicated in head and neck cancer. The current review describes the most common mutations in head and neck cancer: TP53, NOTCH1, HRAS, PIK3CA, and CDKN2A. Emphasis is placed on the involved cellular pathways, clinical correlations, and potential therapeutic interventions. Additionally, the implications of human papillomavirus on mutation patterns are discussed.

Abstract
Bibliometric analyses, which study trends in research productivity, have not previously been applied to hand and wrist research. This study analyses temporal and geographic trends in hand and wrist research from 1988 to 2007. Original research articles were collected from seven English language journals selected on the basis of impact factor. Research production and quality (level of evidence) were determined by country and global region. Linear regression analysis was used to investigate trends. No significant increase in research volume was observed, but journal impact factors have risen significantly since 1988. Western Europe contributed significantly more high-quality (Level I and II) studies than the United States. Research contributions show a geographical distribution concentrated in the US and Western Europe, but considerable changes in this distribution have occurred. From 1988 to 2007, there was a relative increase in research production from Europe, Latin America and Asia, and a relative decline from the US.

Abstract
This abstract will be presented as a proffered talk on Wednesday, September 21, in Plenary Session 8.
African American (AA) and Puerto Rican (PR) men have a higher oral (OSCC) and head and neck squamous cell carcinoma (HNSCC) burden than White men in the United States (US), but the biological basis for these differences are poorly understood. Overall Five-Year relative survival rates for patients diagnosed with oral cavity cancer increased from 53% in 1975 to 63% in 2005 across all races in the US, an increase that parallels a decline in smoking among males during the same period of time. However, the disparity in overall survival rates between Whites and African American patients has remained, practically unchanged from 1975 (19%) to 2005 (18%). The survival disparity difference in HNSCC among AA may be due, among other factors, to a higher prevalence of genetic alterations.
To gain an initial profile of the disparities in genetic alterations between Whites and Non-Whites HNSCC patients we performed a secondary analysis on a convenience sample from an exome-sequencing project that was undertaken at Johns Hopkins School of Medicine. For this project we sequenced ∼18,000 protein-encoding genes in tumors from 17 HNSCC patients which comprised the Discovery set. DNA was purified from these tumors as well as matched non-neoplastic tissue and used to generate libraries suitable for massively parallel sequencing. After capture of the coding sequences with a SureSelect (Agilent) the DNA was sequenced using an Illumina GAIIx/HiSeq instrument. The average coverage of each base in the targeted regions was 77-fold and 92.6% of targeted bases were represented by at least 10 reads in this platform.
The majority of patients (82%) in the Discovery setwere White and the remainder were African American (18%). All the African American patients were smokers. The majority of the AA patients were males (60%), over 60 yrs old (80%) with an oropharyngeal cancer (40%). Using stringent criteria for analysis of these data we identified 249 somatic mutations. The range of confirmed mutations per tumor was 2 to 78, with a mean and standard deviation of 19 ± 16.5 mutations per tumor.
We selected genes for further analysis if they or closely related genes were altered in at least two of the 17 tumors sequenced. The genes included were PIK3AP1, RIMBP2, SI, NRXN2, NRXN3, EPHA7, RASA1, RXFP3, PIK3CA, HRAS, TP53, CDKN2A, NOTCH1, and FBXW7. We then analyzed the sequences of these genes in additional HNSCC and their corresponding normal tissues. In total, somatic mutations in TP53, NOTCH1, CDKN2A, PIK3CA, FBXW7, and HRAS were identified in 47%, 15%, 9%, 6%, 5% and 4% of patients, respectively. Most of the mutations (84%) were observed in White patients. There was no significant difference in the number of mutations per patient in White (14.6) vs African American (13.7) patients. Breaking down the somatic mutations by race we found that the mutations among African Americans was higher (73%) for TP53, when compared to Whites (55%) or to previously observed frequency of TP53 mutations in HNSCC. The mutations in NOTCH1, CDKN2A, PIK3CA had similar mutation frequency in African Americans and in White patients. African American patients did not have somatic mutations in FBXW7 and HRAS.
This is the first exome sequencing study to report HNSCC mutation disparities in African Americans. Although the number of HNSCC African American patients examined in this project is small, the results of this study provide evidence that HNSCCs, although morphologically similar, are comprised of distinct diseases at the molecular level. These results should be examined in a larger cohort of African American patients. Our preliminary findings that HNSCCs have few directly targetable mutations has implications for controlling this disease in the future. In particular, it suggests that prevention, careful surveillance of patients at risk, and early detection are the optimal approaches for reducing cancer health disparities in this disease.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. To explore the genetic origins of this cancer, we used whole-exome sequencing and gene copy number analyses to study 32 primary tumors. Tumors from patients with a history of tobacco use had more mutations than did tumors from patients who did not use tobacco, and tumors that were negative for human papillomavirus (HPV) had more mutations than did HPV-positive tumors. Six of the genes that were mutated in multiple tumors were assessed in up to 88 additional HNSCCs. In addition to previously described mutations in TP53, CDKN2A, PIK3CA, and HRAS, we identified mutations in FBXW7 and NOTCH1. Nearly 40% of the 28 mutations identified in NOTCH1 were predicted to truncate the gene product, suggesting that NOTCH1 may function as a tumor suppressor gene rather than an oncogene in this tumor type.

Abstract
BACKGROUND Whether an increase in the daily oral maintenance dose of clopidogrel may improve clinical outcomes in patients undergoing percutaneous coronary intervention (PCI) is still debated. OBJECTIVES This meta-analysis aimed to estimate the relative effect of a 150- vs. 75-mg daily maintenance dosage of clopidogrel on clinical and laboratory end-points in patients undergoing PCI. METHODS We searched electronic and printed sources (up to 14 December 2010) for both randomized control trials and observational studies satisfying the predefined inclusion criteria. RESULTS We retrieved 12 reports of studies including a total of 23,814 patients. Clopidogrel, 150 mg day(-1), was associated with significant reductions in major adverse cardiac and/or cerebrovascular events (odds ratio [OR], 0.67; 95% confidence interval [CI], 0.48-0.94), myocardial infarction (OR, 0.72; 95% CI, 0.60-0.86), target vessel revascularization (OR, 0.27; 95% CI, 0.12-0.62) and stent thrombosis (OR, 0.64; 95% CI, 0.53-0.77) and decreased adenosine diphosphate-induced maximal platelet aggregation. However, as compared with 75 mg day(-1), the 150-mg daily maintenance dosage significantly increased the risk of minor bleeding (OR, 1.21; 95% CI, 1.08-1.36). CONCLUSION As compared with the currently recommended 75-mg day(-1) maintenance dosage of clopidogrel, the 150-mg day(-1) dosage can reduce major adverse cardiac and/or cerebrovascular events but may increase the risk of minor bleeding.
