RESUMEN
PURPOSE: Individuals with head and neck cancer (HNCa) face myriad biopsychosocial challenges. Even after treatment completion, these challenges may cause continued disablement and diminished quality of life (QoL). Resilience may serve to minimize the disabling impact of HNCa and, in turn, maximize QoL. The purpose of this study was to formally assess resilience in HNCa survivors and explore its relationship with QoL. METHODS: A cross-sectional descriptive study was conducted. Forty HNCa survivors completed three validated, self-report questionnaires pertaining to the collection of resilience and QoL data. Descriptive and correlational analyses were performed. RESULTS: Resilience was identified in HNCa survivors and a positive correlation was found between resilience and QoL. CONCLUSIONS: Data suggest that resilience may buffer the influence of HNCa on QoL. Thus, screening for reduced levels of resilience may proactively facilitate identification of those who are most vulnerable to the psychosocial impact of HNCa. Interventions that foster resilience may ameliorate the challenges of HNCa and maximize QoL.

PURPOSE: Patients treated for oropharyngeal cancer (OPC) are at increased risk for functional decline due to cancer-related impairments and treatment toxicities, often leading to recommendations for enteral nutritional support. This study investigated the natural history of weight and swallowing outcomes in patients with and without feeding tube (FT) placement. METHODS: Data were collected from electronic medical records of OPC patients treated with (chemo)radiotherapy at a single regional cancer center between January 2013 and December 2015. Weight measurements, Functional Oral Intake Scale (FOIS) scores, Performance Status Scale for Head and Neck Cancer (PSS-HN) normalcy of diet scores, and M.D. Anderson Dysphagia Inventory (MDADI) composite scores were gathered at baseline and at 3-, 6-, and 12-months post-treatment. Patients were grouped based on FT placement and change over time was assessed using linear mixed effects analysis. RESULTS: Of 122 eligible patients, 38 (31.1%) received a FT (FT group). Compared with baseline, weight decreased significantly at 3 and 6 months in both groups and at 12 months for patients without a FT (NFT group). Swallowing-related quality of life (QoL) decreased significantly at 3 and 6 months only in the NFT group. CONCLUSION: OPC patients experience clinically relevant decreases in weight and swallowing-related QoL in the first-year post-treatment irrespective of FT placement. These findings will contribute to improved patient monitoring and communication within the clinical setting which may ultimately lead to better outcomes for those with OPC.

Yawning is a stereotyped motor behavior characterized by deep inhalation and associated dilation of the respiratory tract, pronounced jaw opening, and facial grimacing. The frequency of spontaneous yawning varies over the diurnal cycle, peaking after waking and before sleep. Yawning can also be elicited by seeing or hearing another yawn, or by thinking about yawning, a phenomenon known as "contagious yawning". Yawning is mediated by a distributed network of brainstem and supratentorial brain regions, the components of which are shared with other airway behaviors including respiration, swallowing, and mastication. Nevertheless, the possibility of behavioral coordination between yawning and other brainstem-mediated functions has not been examined. Here we show, with a double-blind methodology, a greater-than-fivefold increase in rest (saliva) swallowing rate during the 10-s period immediately following contagious yawning elicited in 14 adult humans through the viewing of videotaped yawn stimuli. Sixty-five percent of yawns were followed by a swallow within 10 s and swallows accounted for 26 % of all behaviors produced during this post-yawn period. This novel finding of a tight temporal coupling between yawning and swallowing provides preliminary evidence that yawning and swallowing are physiologically related, thus extending current models of upper airway physiology and neurophysiology. Moreover, our finding suggests the possibility that yawning plays a role in eliciting rest swallowing, a view not considered in previous theories of yawning. As such, the present demonstration of a temporal association between yawning and swallowing motivates a re-examination of the longstanding question, "Why do we yawn?".

Purpose: In oropharyngeal squamous cell carcinoma (OPSCC), systemic loss of skeletal muscle mass (SMM), or sarcopenia, is a strong prognostic predictor of survival outcomes. However, the relationship between sarcopenia and nutrition-related outcomes is not well understood. This investigation evaluated the prognostic significance of sarcopenia for feeding tube (FT) placement in a cohort of OPSCC patients. Methods and Materials: A retrospective cohort study was conducted with data collected from 194 OPSCC patients treated with definitive radiation therapy (RT) or chemoradiation therapy (CRT). Sarcopenia was assessed from computed tomography imaging at the level of the third cervical (C3) and fourth thoracic (T4) vertebrae. The prognostic nature of pretreatment sarcopenia and its relationship with FT placement was explored using logistic regression. Results: The median age of patients included was 61.0 years, and the majority were male (83%). In this patient cohort, 87.6% underwent concurrent CRT, and 30.9% received a FT over the course of treatment. Sarcopenia was identified at baseline in 72.7% of patients based on C3 SMM measurements and in 41.7% based on measures at the level of T4. Based on measures at both C3 and T4, those with sarcopenia were significantly more likely to receive a FT and had significantly worse freedom from FT placement compared with patients without sarcopenia. Sarcopenia assessed at T4 was a significant predictor of FT placement. Conclusions: SMM measured at T4 may represent a novel and practical biomarker for sarcopenia detection that is associated with the need for FT placement. These findings suggest that the detection of baseline sarcopenia could guide decision-making related to the need for nutritional support in OPSCC patients undergoing RT/CRT.
RESUMEN
OBJECTIVE: To test the hypothesis that oropharyngeal air-pulse application is associated with increased swallowing rates in individuals with dysphagia secondary to stroke. DESIGN: Case control. SETTING: Stroke rehabilitation hospital or home setting. PARTICIPANTS: Convenience sample of individuals (N=8) with new-onset dysphagia after stroke. INTERVENTIONS: Air-pulse trains were applied to the oropharynx of 8 subjects who presented with dysphagia after hemispheric stroke. Resting swallowing rates were determined for 5 experimental conditions: baseline without air-pulse mouthpiece, baseline with mouthpiece in situ, unilateral right oropharyngeal air-pulse, unilateral left oropharyngeal air-pulse, and bilateral oropharyngeal air-pulse application. Individual swallowing responses were analyzed using a 2-SD band method. MAIN OUTCOME MEASURE: Swallowing rate (swallows/min). RESULTS: Swallowing rates associated with bilateral air-pulse application were greater than baseline in 4 of the 8 subjects. The 4 subjects who demonstrated this response to air-pulse application had greater baseline swallowing rates than did subjects whose swallowing rates were not altered in association with air-pulse application. CONCLUSIONS: Oropharyngeal air-pulse trains can be applied in individuals with swallowing impairment. Air-pulse application is associated with increased resting swallowing rates in some individuals with dysphagia secondary to hemispheric stroke. Further research should extend this proof-of-principle study by examining the efficacy of oropharyngeal air-pulse application in terms of improved swallowing and related outcomes in dysphagic stroke through a large randomized trial.

PURPOSE: Management of head and neck cancer (HNC) can result in substantial long-term, multifaceted disability, leading to significant deficits in one's functioning and quality of life (QoL). Consequently, treatment selection is a challenging component of care for patients with HNC. Clinical care guided by shared decision making (SDM) can help address these decisional challenges and allow for a more individualized approach to treatment. However, due in part to the dominance of biomedically oriented philosophies in clinical care, engaging in SDM that reflects the individual patient's needs may be difficult. CONCLUSIONS: In this clinical focus article, we propose that health care decisions made in the context of biopsychosocial-framed care-one that contrasts to decision making directed solely by the biomedical model-will promote patient autonomy and permit the subjective personal values, beliefs, and preferences of individuals to be considered and incorporated into treatment-related decisions. Consequently, clinical efforts that are directed toward biopsychosocial-framed SDM hold the potential to positively affect QoL and well-being for individuals with HNC.

OBJECTIVES: In those undergoing treatment for head and neck cancer (HNC), sarcopenia is a strong prognostic factor for outcomes and mortality. This review identified working definitions and methods used to objectively assess sarcopenia in HNC. METHOD: The scoping review was performed in accordance with Arksey and O'Malley's five-stage methodology and the Joanna Briggs Institute guidelines. INFORMATION SOURCES: Eligible studies were identified using MEDLINE, Embase, Scopus, Cochrane Library, and CINAHL databases. STUDY SELECTION: Inclusion criteria represented studies of adult HNC patients in which sarcopenia was listed as an outcome, full-text articles written in English, and empirical research studies with a quantitative design. DATA EXTRACTION: Eligible studies were assessed using a proprietary data extraction form. General information, article details and characteristics, and details related to the concept of the scoping review were extracted in an iterative process. RESULTS: Seventy-six studies published internationally from 2016 to 2021 on sarcopenia in HNC were included. The majority were retrospective (n = 56; 74%) and the prevalence of sarcopenia ranged from 3.8% to 78.7%. Approximately two-thirds of studies used computed tomography (CT) to assess sarcopenia. Skeletal muscle index (SMI) at the third lumbar vertebra (L3) (n = 53; 70%) was the most prevalent metric used to identify sarcopenia, followed by SMI at the third cervical vertebra (C3) (n = 4; 5%). CONCLUSIONS: Currently, the most effective strategy to assess sarcopenia in HNC depends on several factors, including access to resources, patient and treatment characteristics, and the prognostic significance of outcomes used to represent sarcopenia. Skeletal muscle mass (SMM) measured at C3 may represent a practical, precise, and cost-effective biomarker for the detection of sarcopenia. However, combining SMM measurements at C3 with other sarcopenic parameters-including muscle strength and physical performance-may provide a more accurate risk profile for sarcopenia assessment and allow for a greater understanding of this condition in HNC.

Application of principles of palliative care to the concept of survivorship may serve to establish an interdisciplinary approach to guide those treated for cancer through the experience of being "cured" but not "healed". Valuable lessons may be garnered from palliative care if its principles are considered within the context of survivorship. This work aims to define key terms including cured, healed, survivorship, and quality of life (QoL) and delineate the central tenets of palliative care and disease-modifying care. Since pursuit of a cure tends to dominate provision of oncological care, Western society's prevailing death denying attitudes often equate to the prioritization of advanced medial treatment to postpone death. Accordingly, the "modern paradox" of medicine (Cassell, 2004) is examined in consideration of the suffering that often results from advanced medical treatment that is intended to alleviate the cause of suffering and ultimately, "deny" death. However, owing to the profound consequences of advanced medical treatment and the associated losses of function concomitant with cancer, there is an apparent need for a framework of care that attends to these survivorship issues. When the experience of being cured but not healed is articulated through a theoretical discussion of liminality and the "remission society" (Frank, 1995), the applicability of palliative care to survivorship care becomes apparent. By embracing principles of palliative care, survivorship care may be guided by a theoretical foundation that provides cancer survivors with care that supports increased QoL, biopsychosocial symptom management, and a holistic perspective of the illness experience. Accordingly, application of palliative care to survivorship may establish congruence between notions of cured and healed.

BACKGROUND: Patients with resected oral cavity squamous cell carcinoma (OCSCC) are often treated with adjuvant radiation (RT) ± concomitant chemotherapy based on pathological findings. Standard RT volumes include all surgically dissected areas, including the tumour bed and dissected neck. RT has significant acute and long-term toxicities including odynophagia, dysphagia, dermatitis and fibrosis. The goal of this study is to assess the rate of regional failure with omission of radiation to the surgically dissected pathologically node negative (pN0) hemi-neck(s) compared to historical control, and to compare oncologic outcomes, toxicity, and quality of life (QoL) profiles between standard RT volumes and omission of RT to the pN0 neck. METHODS: This is a multicentre phase II study randomizing 90 patients with T1-4 N0-2 OCSCC with at least one pN0 hemi-neck in a 1:2 ratio between standard RT volumes and omission of RT to the pN0 hemi-neck(s). Patients will be stratified based on overall nodal status (nodal involvement vs. no nodal involvement) and use of concurrent chemotherapy. The primary endpoint is regional failure in the pN0 hemi-neck(s); we hypothesize that a 2-year regional recurrence of 20% or less will be achieved. Secondary endpoints include overall and progression-free survival, local recurrence, rate of salvage therapy, toxicity and QoL. DISCUSSION: This study will provide an assessment of omission of RT to the dissected pN0 hemi-neck(s) on oncologic outcomes, QoL and toxicity. Results will inform the design of future definitive phase III trials. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT03997643 .

While previous research has shown that air-pulse stimulation of the oropharynx facilitates saliva swallowing in young adults, the effects of air pulses in older adults have not been examined. Responses to air-pulse stimulation may differ in young and older adults given age-related changes in sensation, swallowing physiology, and swallow-related brain activation. Therefore, this study sought to determine the effects of oropharyngeal air-pulse stimulation on saliva swallowing rates in 18 healthy older adults. Saliva swallowing rates were monitored across six conditions: baseline without mouthpiece, baseline with mouthpiece in situ, unilateral right oropharyngeal stimulation, unilateral left oropharyngeal stimulation, bilateral oropharyngeal stimulation, and sham stimulation. Results indicated that bilateral oropharyngeal air-pulse stimulation was associated with a statistically significant increase in mean saliva swallowing rate compared to baseline without mouthpiece, baseline with mouthpiece in situ, and sham stimulation. In previous studies, young adults reported an irrepressible urge to swallow in response to oropharyngeal air-pulse delivery, but the older adults in the current study did not perceive the air-pulse stimulation as being associated with swallowing or other behaviors. These findings indicate that oropharyngeal air-pulse stimulation facilitates the elicitation of saliva swallowing in older adults.

PIK3CA is the only frequently-mutated, directly druggable oncogene in head and neck squamous cell carcinoma (HNSCC). However, it is unclear if a molecularly-driven intervention trial can be launched successfully, particularly within a single-institution setting secondary to the infrastructure necessary for mutation detection, mutation prevalence, and patient willingness to participate. This study aimed to evaluate 1) local frequency of PIK3CA activating mutations in HNSCC, 2) timeliness of our mutation-profiling clinical pathway, and 3) patients' willingness to enroll in a novel neoadjuvant drug trial. Tissue biopsies of 25 consecutive cases of HNSCC were tested for activating PIK3CA mutations at three mutational hotspots by real-time polymerase chain reaction. Mutations prevalence and number of working days accrued in determining PIK3CA mutational status were calculated. In addition, 30 HNSCC patients were surveyed prospectively regarding their willingness to participate in a hypothetical drug trial. Survey data were summarized descriptively. 4 of 25 (16 %) tumors harbored a PIK3CA activating mutation, including one at codon E542K, two at codon E545K/D, and one at codon H1047R. On average, this result was obtained in approximately 15 working days (range, 9-24 working days). The majority of patients surveyed (70 %) indicated their willingness to participate in a targeted PIK3CA trial. This study provides evidence that within a single institution, PIK3CA activating mutations can be detected with expected frequency, with sufficient timeliness and sufficient patient interest to mount a targeted intervention trial that may lead to improved tumor response in selected HNSCC patients.

UNLABELLED: Based on society's expectations of what defines the norms for what is deemed "masculine" and "feminine", and a propensity for society's members to adhere to these expectations, women may face a unique set of circumstances and pressures following surgical treatment for laryngeal cancer. This is primarily due to the changes that occur to women's physical, psychological, and social functioning when dealing with cancer diagnosis and treatment outcomes. Because of concerns related to physical disfigurement, acoustic and perceptual changes to one's voice, and threat of the psychological sequelae associated with total laryngectomy (TL) (or, the surgical removal of one's voicebox and surrounding structures), there is an increased potential for violation of social expectations that cross these areas of functioning. As such, efforts that seek to better understand the potentially differential impact of TL on women and identify the specific needs they may have leading up to and after such treatment pursuant to contemporary societal expectations are warranted. Thus, this paper provides an examination of the potentially differential impact of TL on women. In addressing this position, this paper examines the unique challenges women may face postlaryngectomy through the framework of the International Classification of Functioning, Disability, and Health (ICF). Through the use of the ICF, this paper will provide an expanded perspective related to the interactions between body functioning, active participation in daily activities, and contextual factors that may act as facilitators or barriers to women's societal reintegration secondary to TL. LEARNING OUTCOMES: Readers will be able to describe the multiple factors that may contribute to the differential impact of total laryngectomy (TL) on women. More specifically, readers will gain an understanding about women's physical, psychological, and social functioning secondary to TL. This paper also provides readers with exposure to the World Health Organization's International Classification of Functioning, Disability, and Health (ICF) framework. This framework provides readers with an expanded perspective related to the interactions between body functioning, active participation in daily activities, and contextual factors that may act as either facilitators or barriers to the societal reintegration of women secondary to TL.

BACKGROUND: In 2001, the World Health Organization developed the International Classification of Functioning, Disability, and Health (ICF) framework in an effort to attend to the multidimensional health-related concerns of individuals. Historically, although the ICF has frequently been used in a rehabilitation-based context, the World Health Organization has positioned it as a universal framework of health and its related states. Consequently, the ICF has been utilized for a diverse array of purposes in the field of oncology, including: evaluating functioning in individuals with cancer, guiding assessment in oncology rehabilitation, assessing the comprehensiveness of outcome measures utilized in oncology research, assisting in health-related quality of life instrument selection, and comparing the primary concerns of health professionals with those of their patients. DISCUSSION: Examination of the ICF through the lens of cancer care highlights the fact that this framework can be a valuable tool to facilitate comprehensive care in oncology, but it currently possesses some areas of limitation that require conceptual revision; to this end, several recommendations have been proposed. Specifically, these proposed recommendations center on the following three areas of the ICF framework: (1) the replacement of the term "health condition" with the more inclusive and dynamic term "health state;" (2) the continuing development and refinement of the personal factors component to ensure issues such as comorbidities can be accounted for appropriately; and (3) the inclusion of a mechanism to account for the subjective dimension of health and functioning (eg, quality of life). SUMMARY: It is through the expansion of these conceptual parameters that the ICF may become more relevant and applicable to the field of oncology. With these important revisions, the ICF has the potential to provide a broader biopsychosocial perspective of care that captures the diverse range of concerns that arise throughout the continuum of care in oncology.
RESUMEN
Due to significant differences in healthcare structure between the United States and Canada, there are unique barriers to adopting new medical technology in Canada. In this article, we describe our experience developing a transoral robotic surgery (TORS) program at Western University. Specifically, we outline the steps that were necessary to obtain institutional and multidisciplinary team approval, financial support, as well as surgeon and allied healthcare personnel training. This experience can potentially be used as a roadmap for other Canadian institutions pursuing a TORS program.

PURPOSE: This work examines the environmental factors component of the International Classification of Functioning, Disability, and Health (ICF) relative to current health-facilitating evidence about natural environmental factors. We argue that the environmental factors component warrants reconceptualization in order to offer an extended and more systematic framework for identifying and measuring health-facilitating natural environmental factors. METHOD: Current evidence highlighting the potential health-facilitating benefits of natural environmental factors is synthesized and considered in the context of the ICF framework and its coding system. RESULTS: In its current form, the ICF's conceptual framework and coding system are inadequate for identifying and measuring natural environmental factors in individuals and groups with and/or without health conditions. CONCLUSION: The ICF provides an advanced framework for health and disability that reflects contemporary conceptualizations about health. However, given the scope of emerging evidence highlighting positive health and well-being outcomes associated with natural environmental factors, we believe the environmental factors component requires further advancement to reflect this current knowledge. Reconceptualizing the environmental factors component supports a more holistic interpretation of the continuum of environmental factors as both facilitators and barriers. In doing so, it strengthens the ICF's utility in identifying and measuring health-facilitating natural environmental factors.

This study sought to determine whether air-pulse trains delivered to the peritonsillar area would facilitate swallowing in healthy subjects. Trains of unilateral or bilateral air pulses were delivered to the peritonsillar area via tubing embedded in a dental splint, while swallows were simultaneously identified from their associated laryngeal and respiratory movements. Results from four subjects indicated that oropharyngeal air-pulse stimulation evoked an irrepressible urge to swallow, followed by an overt swallow as verified by laryngeal and respiratory movements. Moreover, air-pulse stimulation was associated with a significant increase in swallowing frequency. Mean latency of swallowing following bilateral stimulation tended to be less than the latency of swallowing following unilateral stimulation. These findings in healthy adults suggest the possibility that oropharyngeal air-pulse stimulation may have clinical utility in dysphagic individuals.
