RESUMO
Head and neck cancer (HNC) guidelines recommend regular multidisciplinary team (MDT) monitoring and early intervention to optimize dysphagia outcomes; however, many factors affect the ability to achieve these goals. The aims of this study were to explore the barriers/facilitators to establishing and sustaining a MDT HNC care pathway and to examine the dysphagia-related speech-language pathology (SLP) and dietetic components of the pathway. Using the Consolidated Framework for Implementation Research (CFIR), a mixed methods study design was used to evaluate an established MDT HNC pathway. Ten MDT members provided perceptions of facilitators/barriers to implementing and sustaining the pathway. Patients attending the SLP and dietetic components of the pathway who commenced treatment between 2013 and 2014 (n = 63) were audited for attendance, outcome data collected per visit, and swallowing outcomes to 24-month post-treatment. Dysphagia outcomes were compared to a published cohort who had received intensive prophylactic dysphagia management. Multiple CFIR constructs were identified as critical to implementing and sustaining the pathway. Complexity was a barrier. Patient attendance was excellent during treatment, with low rates of non-compliance (< 15%) to 24 months. Collection of clinician/patient outcome tools was good during treatment, but lower post-treatment. Dysphagia outcomes were good and comparable to prior published data. The pathway provided patients with access to regular supportive care and provided staff opportunities to provide early and ongoing dysphagia monitoring and management. However, implementing and sustaining a HNC pathway is complex, requiring significant staff resources, financial investment, and perseverance. Regular audits are necessary to monitor the quality of the pathway.

Evidence supporting prophylactic swallow exercises for patients with head and neck cancer (HNC) has not been universally demonstrated. This RCT examined diet level, feeding tube use, swallow function, and quality of life (QOL) of patients undergoing chemoradiotherapy who performed prophylactic swallowing exercises. Sixty HNC patients were randomized into exercise versus control groups. Swallowing, oromotor, toxicity, and QOL data were recorded (baseline, 3, 6, 12, 24 months). Physiological swallow function was examined at baseline and 3 months. Swallow exercises were completed twice daily. Oral intake at 3 months was 10% better in the exercise group, which was not statistically significant (p = 0.49). Significant (p < 0.05) differences in secondary outcomes including oromotor function, pharyngeal impairment, oral pharyngeal swallow efficiency, and incisal opening were noted at early time points (3-6 months) in the exercise group. Possible positive early improvements in swallow function are associated with swallowing exercises, although these improvements are not significant longer term.

OBJECTIVE: To develop an expert consensus statement (ECS) on the management of dysphagia in head and neck cancer (HNC) patients to address controversies and offer opportunities for quality improvement. Dysphagia in HNC was defined as swallowing impairment in patients with cancers of the nasal cavity, paranasal sinuses, nasopharynx, oral cavity, oropharynx, larynx, or hypopharynx. METHODS: Development group members with expertise in dysphagia followed established guidelines for developing ECS. A professional search strategist systematically reviewed the literature, and the best available evidence was used to compose consensus statements targeted at providers managing dysphagia in adult HNC populations. The development group prioritized topics where there was significant practice variation and topics that would improve the quality of HNC patient care if consensus were possible. RESULTS: The development group identified 60 candidate consensus statements, based on 75 initial proposed topics and questions, that focused on addressing the following high yield topics: (1) risk factors, (2) screening, (3) evaluation, (4) prevention, (5) interventions, and (6) surveillance. After 2 iterations of the Delphi survey and the removal of duplicative statements, 48 statements met the standardized definition for consensus; 12 statements were designated as no consensus. CONCLUSION: Expert consensus was achieved for 48 statements pertaining to risk factors, screening, evaluation, prevention, intervention, and surveillance for dysphagia in HNC patients. Clinicians can use these statements to improve quality of care, inform policy and protocols, and appreciate areas where there is no consensus. Future research, ideally randomized controlled trials, is warranted to address additional controversies related to dysphagia in HNC patients.

Do the Roberts-Sloan (RS) or modified Kasting-Smith-Cooper (KSC) equations that provide good fit to data for maximum flux, from water through mouse or human skin also provide a good fit to data for maximum fluxes through silicone membranes (polydimethylsiloxane, PDMS). The maximum fluxes through silicone membranes from water (J(MPAQ)), molecular weights (MW), solubilities in isopropyl myristate (S(IPM)) and water (S(AQ)) of 31 prodrugs and one parent drug have been fitted to the RS equation, which includes a parameter for dependence on S(AQ), and the KSC equation, which does not, to determine which equation gave the better fit. In addition, the J(MPAQ), MW, S(AQ) and solubilities in octanol (S(OCT)) of 26 diverse molecules from other laboratories were collected and fitted to the RS and KSC equations to determine if the choice of lipid parameter (S(IPM) or S(OCT)) had an effect on which equation gave the better fit. RS gave the better fit to the present prodrug database where: logJ(MPAQ)=-2.454+0.716 logS(IPM)+0.284 logS(AQ)+0.00208 MW, r(2)=0.77. RS also gave the better fit to the database from other laboratories where: logJ(MPAQ)=-2.046+0.667 logS(OCT)+0.333 logS(AQ)-0.00374 MW, r(2)=0.878 after four obvious outliers were removed to give n=22. Thus, data for J(MPAQ) can be fitted to the RS equation, which also provides the best fit to maximum flux from water through mouse or human skin and includes a dependence on S(AQ).

AIM: This study examined the effect of mastery learning on new graduate nurses' skill and self-regulation practices for indwelling urinary catheter insertion in a simulated learning environment. BACKGROUND: Clinical competence is a patient safety imperative, it is therefore important to use the most effective approaches to prepare competent nurses resulting in improved patient care and clinical outcomes. Catheter associated Urinary Tract Infections (CaUTI) are a nursing quality indicator, and account for 30% of all Hospital-Acquired Conditions (HAC) annually in the US. DESIGN: A longitudinal randomized control trial to compare two learning groups. SETTING: Large acute care health system. PARTICIPANTS: 40 Nurses with a Bachelor of Science Degree in Nursing (BSN) and who were new graduate nurses. METHOD: Participants were randomized into the experimental group (mastery learning) or the control group (traditional learning). Both groups were asked to complete a self-paced computerized instructional module that reviewed the procedural steps for the insertion of an indwelling urinary catheter in a female prior to the initial assessment. This study examined performance of insertion of a urinary catheter initially and at one-month post intervention and the self-regulation practices of all participants. RESULTS: The mean Survey of Academic Self-Regulation (SASR) scores between groups was significant, pâ¯=â¯.035. The mean change in the Performance Assessment Tool (PAT) 17-critical steps scores between groups was also significant, pâ¯=â¯.013. CONCLUSION: Retention of the critical steps is valuable because if performed incorrectly, these steps may cause harm to the patient. Self-regulation practices promote confidence and an intrinsic motivation to ask for help when clinical practice questions arise.

Purpose. To analyze the patterns and associations of adjunctive service visits by head and neck cancer patients receiving primary, concurrent chemoradiation therapy. Methods. Retrospective chart review of patients receiving adjunctive support during a uniform chemoradiation regimen for stages III-IV head and neck squamous cell carcinoma. Univariate and multivariate models for each outcome were obtained from simple and multivariate linear regression analyses. Results. Fifty-two consecutive patients were assessed. Female gender, single marital status, and nonprivate insurance were factors associated with an increased number of social work visits. In a multivariate analysis, female gender and marital status were related to increased social work services. Female gender and stage IV disease were significant for increased nursing visits. In a multivariate analysis for nursing visits, living greater than 20 miles between home and hospital was a negative predictive factor. Conclusion. Treatment of advanced stage head and neck cancer with concurrent chemoradiation warrants a multidisciplinary approach. Female gender, single marital status, and stage IV disease were correlated with increased utilization of social work and nursing services. Distance over 20 miles from the center was a negative factor. This information may help guide the treatment team to allocate resources for the comprehensive care of patients.
RESUMO
Objective. We reviewed a cohort of patients with previously untreated locoregional advanced head and neck squamous cell carcinoma (HNSCC) who received a uniform chemoradiotherapy regimen. Methods. Retrospective review was performed of 105 patients with stage III or IV HNSCC treated at Greater Baltimore Medical Center from 2000 to 2007. Radiation included 125 cGy twice daily for a total 70 Gy to the primary site. Chemotherapy consisted of cisplatin (12 mg/m(2)/h) daily for five days and 5-fluorouracil (600 mg/m(2)/20 h) daily for five days, given with weeks one and six of radiation. All but seven patients with N2 or greater disease received planned neck dissection after chemoradiotherapy. Primary outcomes were overall survival (OS), locoregional control (LRC), and disease-free survival (DFS). Results. Median followup of surviving patients was 57.6 months. Five-year OS was 60%, LRC was 68%, and DFS was 56%. Predictors of increased mortality included age ≥55, female gender, hypopharyngeal primary, and T3/T4 stage. Twelve patients developed locoregional recurrences, and 16 patients developed distant metastases. Eighteen second primary malignancies were diagnosed in 17 patients. Conclusions. The CRT regimen resulted in favorable outcomes. However, locoregional and distant recurrences cause significant mortality and highlight the need for more effective therapies to prevent and manage these events.
RESUMO
BACKGROUND: The purpose of this study was to elucidate factors associated with pharyngoesophageal strictures after treatment for head and neck squamous cell carcinoma (SCC). METHODS: We conducted a retrospective review of patients receiving cisplatin and 5-fluorouracil chemotherapy combined with concurrent hyperfractionated radiation therapy for oropharyngeal squamous cell carcinoma. RESULTS: Strictures developed in 13 of 67 patients (19%). Strictures were associated with tumor location (tonsil vs base of tongue; p = .03), neck dissection after completion of therapy (p = .03), and the duration of treatment-induced mucositis (weeks with mucositis grade ≥2; National Cancer Institute (NCI) Common Toxicity Criteria; p < .001). Age, sex, race, tumor stage, nodal stage, American Joint Committee on Cancer (AJCC) stage, human papillomavirus (HPV) status, smoking, radiation dose, maximum severity of mucositis, amifostine use, and pretreatment swallow dysfunction were not significantly associated with stricture. In multivariate analysis, only duration of mucositis, after controlling for age, sex, and tumor location, remained highly significant (p < .01). CONCLUSION: The duration of treatment-related mucositis is an independent risk factor for stricture formation in patients with oropharyngeal SCC treated with concurrent chemotherapy and radiation therapy.

OBJECTIVES/HYPOTHESIS: The human papillomavirus (HPV) has been identified as a causative factor in 20% to 25% of all head and neck squamous cell carcinomas (HNSCC). Ongoing research suggests that the presence of HPV DNA in HNSCC predicts a positive prognosis with respect to disease-free and overall survival. However, most studies have been limited by the heterogeneity in treatment regimens and/or anatomic subsites of tumor origin. In this study, we correlate clinical outcomes with HPV status for patients with oropharyngeal carcinomas who were uniformly treated with a concurrent chemoradiation treatment protocol. STUDY DESIGN: Retrospective study. METHODS: Demographic and clinicopathologic parameters, including age at diagnosis, gender, race, smoking and alcohol history, tumor stage and grade, locoregional recurrence, metastatic spread, recurrence-free survival, overall survival and disease-specific death, were obtained from medical charts and established databases. These parameters were correlated with HPV status of the tumors established by in situ hybridization analysis. RESULTS: HPV positivity correlated with improved clinical outcomes regarding locoregional control (P = .042), recurrence-free survival (P = .009), overall survival (P = .017), and disease-specific death (P = .09). Advanced T stage was a significant risk factor for recurrence and death independent of HPV status. CONCLUSIONS: In patients with oropharyngeal carcinoma uniformly treated with chemoradiation, the presence of HPV is a favorable prognostic indicator with respect to recurrence and overall survival. However, advanced T stage was an independent risk factor for recurrence and death that can to some degree offset this benefit.

PURPOSE: To determine whether the fluxes through hairless mouse skin for three homologous series of prodrugs of 5-fluorouracil (5-FU, 1) and 6-mercaptopurine (6-MP, 2) from saturated aqueous suspensions show dependencies on aqueous (SAQ) and isopropyl myristate (SIPM) solubilities similar to those shown by the identical compounds delivered from IPM. METHODS: Flux through hairless mouse skin from water (JMAQ) and solubility data were measured for a homologous series of six 3-alkylcarbonyloxymethyl (ACOM) prodrugs of 5-FU (3-ACOM-5-FU), and five 6-ACOM-6-MP prodrugs, then combined with literature data for five bis-6,9-ACOM-6-MP prodrugs to give a data base. Multiple linear regression using SPSS 7.5 was performed on log SIPM, log SAQ, molecular weight and log JMAQ data to determine the best fit coefficients to the transformed Potts-Guy equation: log JMAQ = x + y log SIPM + (1 - y) log SAQ + z MW. Permeability coefficients (PMAQ) were calculated from JMAQ/SAQ. RESULTS: The best fit coefficients for the flux from AQ(JMAQ) were x = -1.497, y = 0.660 and z = -0.00469 (r2 = 0.765) with an average error of prediction equal to 0.193 log units. The best fit coefficients for the flux from IPM (JMIPM) were x = -0.557, y = 0.536 and z = -0.00261 (r2 = 0.941) with an average error of prediction equal to 0.109 log units. For all three series, log PMAQ increased whereas log PMIPM decreased with increasing alkyl chain lengths in the promoiety and with decreasing solubility parameter values. CONCLUSIONS: The transformed Potts-Guy equation can be used to predict JMAQ but with less certainty than JMIPM. SIPM and SAQ have consistently been shown to have a positive influence on JMIPM, and now on JMAQ, with a balance between the two solubilities being obviously important. The previous observation that log PMAQ increased with lipophilicity is an artifact of normalizing JMAQ by SAQ.
