RESUMO
LAY ABSTRACT: Later autism diagnosis is associated with risk for mental health problems. Understanding factors related to later autism diagnosis may help reduce mental health risks for autistic people. One characteristic associated with later autism diagnosis is female sex. However, studies often do not distinguish sex assigned at birth and gender identity. Gender diversity may be more common in autistic relative to neurotypical people, and autism is more common in gender-diverse populations. We studied age at autism diagnosis by sex assigned at birth, gender identity, and gender diversity (gender-diverse vs cisgender) status, separately. We studied three separate autistic samples, each of which differed in how they were diagnosed and how they were recruited. The samples included 193 persons (8.0-18.0 years) from a research-recruited academic medical center sample; 1,550 people (1.3-25.4 years) from a clinic-based sample; and 244 people (18.2-30.0 years) from a community-enriched sample. We found significant differences in the clinic-based and community-enriched samples. People assigned female sex at birth were diagnosed with autism significantly later than people assigned male at birth. People of female gender were diagnosed significantly later than people of male gender. Gender-diverse people were diagnosed significantly later than cisgender people. Sex assigned at birth, gender identity, and gender diversity may each show unique relationships with age of autism diagnosis. Differences in how autistic people are diagnosed and recruited are important to consider in studies that examine sex assigned at birth or gender identity. More research into autism diagnosis in adulthood is needed.
RESUMO
Poor sleep can have a significant impact on physical health and well-being. Sleep problems are common among autistic children, but less is known about sleep across the autistic adult lifespan. Autistic adults (n = 730, aged 18-78 years) were recruited via Simons Powering Autism Research for Knowledge Research Match. Participants completed online surveys asking about demographics, health problems, social support, symptoms of anxiety and depression, and overall and specific aspects of sleep quality. Regression analyses explored the variables associated with sleep quality. Physical health, assigned female sex at birth and self-reported anxiety symptoms significantly contributed to models for all aspects of sleep. Perceived stress contributed to models of overall and subjective sleep quality, and daytime dysfunction. Depression symptoms did not contribute significantly to any of the models of sleep quality. However, utilizing government support mechanisms (such as social security) contributed to the model of sleep efficiency. Age contributed little to models of sleep quality, whereas perceived stress and psychotropic medication use contributed to some but not all aspects of sleep. Sleep quality is poor for autistic people across the adult lifespan. Given known impacts of poor sleep on health, cognition and quality of life, attention should be paid to sleep and its possible everyday effects for autistic people of all ages.

Purpose: Treatment patterns for head and neck squamous cell carcinoma (HNSCC) vary among older adults because of concerns about their health status. Geriatric assessment may guide treatment for older adults with HNSCC by assessing their health status. Methods and Materials: We conducted a retrospective review of adjuvant treatment received by older patients with HNSCC who completed a novel geriatric assessment, the electronic Rapid Fitness Assessment, before treatment. The electronic Rapid Fitness Assessment yields an accumulated geriatric deficits (AGD) score. Higher AGD score indicates greater frailty. Comparators were age and performance status. The Wilcoxon rank sum test compared differences between those who did and did not receive adjuvant radiation therapy and chemotherapy. Results: The cohort included 73 patients, of whom 56 (77%) had oral cavity cancer. The most common geriatric deficits were major distress, social activity limitation, depression, and impaired activities of daily living. AGD score, age, and performance status were not associated with receipt of adjuvant radiation. Patients who received adjuvant chemotherapy had a significantly lower median AGD score than those who did not (3 vs 6; P = .044), but there was no association with age and performance status. Of the 17 patients with newly diagnosed disease and either positive margins or extranodal extension, only 9 received adjuvant radiation and only 3 received systemic therapy. Most often, systemic therapy was omitted because of patient preference or comorbidities and poor performance status. There was a nonstatistically significant lower AGD score between patients who did and did not receive standard fractionated radiation therapy (median, 4 vs 6.5; P = .13). Conclusions: Receipt of adjuvant chemotherapy was associated with frailty. Rates of chemotherapy utilization were very low, indicating the need for novel strategies to mitigate the toxicity burden in this patient population. Receipt of adjuvant radiation therapy was not associated with frailty; however, there was a trend toward lower frailty among those who did receive radiation therapy.
RESUMO
Despite notable scientific and medical advances, broader political, socioeconomic and behavioural factors continue to undercut the response to the COVID-19 pandemic1,2. Here we convened, as part of this Delphi study, a diverse, multidisciplinary panel of 386 academic, health, non-governmental organization, government and other experts in COVID-19 response from 112 countries and territories to recommend specific actions to end this persistent global threat to public health. The panel developed a set of 41 consensus statements and 57 recommendations to governments, health systems, industry and other key stakeholders across six domains: communication; health systems; vaccination; prevention; treatment and care; and inequities. In the wake of nearly three years of fragmented global and national responses, it is instructive to note that three of the highest-ranked recommendations call for the adoption of whole-of-society and whole-of-government approaches1, while maintaining proven prevention measures using a vaccines-plus approach2 that employs a range of public health and financial support measures to complement vaccination. Other recommendations with at least 99% combined agreement advise governments and other stakeholders to improve communication, rebuild public trust and engage communities3 in the management of pandemic responses. The findings of the study, which have been further endorsed by 184 organizations globally, include points of unanimous agreement, as well as six recommendations with >5% disagreement, that provide health and social policy actions to address inadequacies in the pandemic response and help to bring this public health threat to an end.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent condition that requires a comprehensive and coordinated response across sectors and disciplines. AIMS: In the absence of a multisectoral framework to tackle this condition, we developed one using the sustainable development goals (SDGs) as the basis for converging thinking about the design and delivery of public health responses. METHODS: A multidisciplinary group identified the SDG targets and indicators for inclusion in the new framework through a two-stage process. Firstly, a core team of three researchers independently reviewed the 169 targets and 231 indicators of the SDGs to select a shortlist. Over two Delphi rounds, a multidisciplinary group of 12 experts selected which of the shortlisted targets and indicators to include. Respondents also provided written feedback on their selection. Targets and indicators with 75% or greater agreement were included in the final framework. RESULTS: The final framework comprises 16 targets-representing 9% of all targets and 62% (16/26) of the shortlisted targets-and seven indicators, accounting for 50% (7/14) of the shortlisted indicators and 3% of all indicators. The selected targets and indicators cover a broad range of factors, from health, food and nutrition to education, the economy, and the built environment. CONCLUSIONS: Addressing the challenge of NAFLD will require a re-envisioning of the liver health landscape, with greater focus on joined-up systems thinking and action. This new framework can help guide this process, including by outlining the stakeholders with whom the liver health community needs to engage.

PURPOSE: Older adults with head and neck cancer have increased postoperative complications, longer hospital stays, and higher rates of mortality. Geriatric assessment (GA) provides a measure of overall health status and is preferable to using age alone for assessing fitness for surgery. We sought to determine whether a patient's frailty as determined by a novel electronic GA is associated with outcomes after head and neck cancer (HNC) surgery. METHODS: We conducted a retrospective review of 159 patients aged 75 and older referred to the Geriatrics Service at Memorial Sloan Kettering Cancer Center for pre-operative evaluation prior to undergoing HNC surgery. All patients completed the electronic Rapid Fitness Assessment (eRFA) within 60 days prior to surgery. The accumulated geriatric deficit (AGD) score includes twelve domains from the eRFA with a point assigned for each domain in which there is a deficit and a final point related to comorbidities. Three other metrics were individually assessed: age, Karnofsky Performance Scale (KPS), and number of comorbidities. We utilized multivariable linear regression and t-tests to determine whether frailty is associated with longer length of hospital stay, 30-day intensive care unit (ICU) admission, and 30-day and 90-day postoperative mortality. RESULTS: Patients with a higher AGD score spent more time in the hospital post-operatively (1.0 day increase per unit increase in AGD; 95% CI: 0.21-1.9; p = 0.015). Lower KPS was also associated with statistically significant longer length of stay (-2.70 day change per increasing index KPS; 95% CI: -4.30 - -1.00; days; p = 0.002), while age and comorbidity were not found to be statistically associated with length of stay. Higher AGD score remained significantly associated with longer length of stay on multivariable analysis (0.93 day increase per unit increase in AGD; 95% CI 0.15-1.71; p = 0.019). AGD was the only metric associated with increased risk of ICU admission (6.6 vs 5.0 geriatric deficits for those admitted vs not admitted to ICU; p = 0.024). CONCLUSIONS: Frailty is associated with increased length of hospital stay and ICU admission in older adults with HNC undergoing surgery. GA can be used to counsel patients on the expected postoperative course.

Importance: Modern precision radiotherapy is an innovative and effective treatment of cancer, yet it is unclear how radiotherapy trials are affected by expanding targeted and immune therapies and declining National Institutes of Health funding. Objective: To analyze and compare the characteristics of radiotherapy trials with other oncological trials registered on ClinicalTrials.gov. Design, Setting, and Participants: This is a cross-sectional analysis of trials registered on ClinicalTrials.gov between June 1, 2007, and May 8, 2017. Records of all 243â¯758 clinical studies registered by May 8, 2017, were downloaded, but only 25 907 interventional oncological trials registered between June 1, 2007, and May 8, 2017, and whose primary purpose was "treatment" were included in the final analysis. Trials were categorized according to cancer type and other registration information. Main Outcomes and Measures: Characteristics of radiotherapy trials were compared with characteristics of other oncological trials. Chronological shifts in radiotherapy trials were also analyzed. Results: Of the 25â¯907 trials selected, 1378 (5.3%) were radiotherapy trials and 24 529 (94.7%) were other oncological studies. The number of radiotherapy trials increased gradually from 94 (June 1, 2007, through May 31, 2008) to 192 (June 1, 2015, through May 31, 2016). Radiotherapy trials were less likely than other oncological studies to be registered before participant enrollment (763 of 1370 [55.7%] vs 16 105 of 24 434 [65.9%]; P < .001), to be blinded (45 of 1378 [3.3%] vs 2784 of 24 529 [11.3%]; P < .001), or to involve multiple geographic regions (2.4% vs 9.5%; P < .001), but they were more likely to be phase 2 to 3 (773 of 1124 [68.8%] vs 12 910 of 22 300 [57.9%]; P < .001) and to have a data-monitoring committee (839 of 1264 [66.4%] vs 11 728 of 21 060 [55.7%]; P < .001). Only a minority of radiotherapy trials were industry sponsored, which was significantly lower than for other oncological trials (80 of 1378 [5.8%] vs 10 651 of 24 529 [43.4%]; P < .001; adjusted odds ratio, 0.08; 95% CI, 0.06-0.10). The number of National Institutes of Health-sponsored radiotherapy trials decreased from 80 of 544 trials (14.7%) from 2007 to 2012 to 72 of 834 trials (8.6%) from 2012 to 2017 (P < .001). Radiotherapy trials with a sample size of more than 100 patients decreased from 155 of 543 trials (28.5%) from 2007 to 2012 to 157 of 833 trials (18.8%) from 2012 to 2017 (P < .001). Conclusions and Relevance: The limited number of and the scarcity of funding for radiotherapy trials is concerning given the integral role of radiotherapy in the clinical management of patients with cancer worldwide. A multidisciplinary collaboration to promote and fund more radiotherapy research is warranted.

Because of its sharp lateral penumbra and steep distal fall-off, proton therapy offers dosimetric advantages over photon therapy. In head and neck cancer, proton therapy has been used for decades in the treatment of skull-base tumors. In recent years the use of proton therapy has been extended to numerous other disease sites, including nasopharynx, oropharynx, nasal cavity and paranasal sinuses, periorbital tumors, skin, and salivary gland, or to reirradiation. The aim of this review is to present the physical properties and dosimetric benefit of proton therapy over advanced photon therapy; to summarize the clinical benefit described for each disease site; and to discuss issues of patient selection and cost-effectiveness.

BACKGROUND: There has been limited evaluation of tools for teaching social determinants of health (SDOH). OBJECTIVE: We evaluated a field trip as a tool for teaching SDOH to incoming medical interns. METHODS: Incoming interns from The George Washington University participated in a bus field trip of Washington, DC, guided by community partners. The field trip introduced trainees to local neighborhoods. Pre- and postactivity surveys developed by the authors were analyzed using a Wilcoxon signed rank test. Reflection responses were recorded and counted for recurrent themes. RESULTS: Incoming interns participated in 2015 (85 of 90, 94%) and in 2016 (96 of 116, 83%). Postactivity, basic knowledge of DC geographic health disparities increased, and a greater percentage of interns reported being at least somewhat comfortable understanding the neighborhoods from which their patients come (2015: 58% versus 89%, P < .0001; 2016: 65% versus 88%, P < .0001); identifying challenges to health care that affect low-income patients (2015: 74% versus 90%, P < .0023); describing community resources (2015: 29% versus 67%, P < .0001; 2016: 29% versus 50%, P < .0001); and referring patients to local community resources (2015: 25% versus 64%, P < .0001; 2016: 36% versus 52%, P < .0001). Interns reported that this experience improved their understanding of patients' background and local resources, and that they would change the way they practice. CONCLUSIONS: A bus field trip guided by community partners is a feasible way to increase residents' perception of their understanding of local disparities and comfort in addressing SDOH.

PURPOSE: The aim of this study was to estimate the prevalence of trismus in oral and oropharyngeal cancer patients (OOPC) treated with intensity-modulated radiation therapy (IMRT) and to identify the role of risk factors in patients who developed trismus. MATERIALS AND METHODS: A retrospective cohort study of OOPC treated with IMRT in our institution from 2009 to 2014 was performed. Patients eligible for this study had pre-RT and post-RT maximal inter-incisal opening (MIO) measurements at 6-48 months post-RT, treated with high-dose radiation (≥60 Gy) and pre-RT MIO ≥36 mm. A descriptive analysis to identify the incidence of trismus, with trismus stated as MIO ≤35 mm at or after 6 months post-RT measurement was performed. The role of risk factors such as age, gender, tumor site, tumor size (T), tumor stage, pre-RT MIO measurements and radiation dose to the tumor were assessed using Fisher exact test and the radiation doses to the ipsilateral muscles of mastication in patients who developed trismus were assessed by matching with control (non-trismus) patients using Wilcoxon Signed Rank test. RESULTS: The study consisted of 54 patients with a median age of 55 years and 81% were males. The median follow-up time was 10 months. The prevalence of trismus was 14.8%. Patients with pre-RT MIO measurements ≤40 mm were at risk of developing trismus (P < 0.001). In trismus patients, the average mean radiation dose to the masseter and medial pterygoid muscles was numerically higher but not significantly different (P = 0.08; P = 0.22, respectively) to matched control patients. Age, gender, radiation dose to the tumor, tumor site, size (T) and stage were also found to be not significant. CONCLUSION: Pre-RT MIO measurement was a significant risk factor for the development of trismus. However, this is a non-modifiable factor. Limiting radiation dose to the muscles of mastication could prevent this complication.

Next-generation sequencing has evolved technically and economically into the method of choice for interrogating the genome in cancer and inherited disorders. The introduction of procedural code sets for whole-exome and genome sequencing is a milestone toward financially sustainable clinical implementation; however, achieving reimbursement is currently a major challenge. As part of a prospective quality-improvement initiative to implement the new code sets, we adopted Agile, a development methodology originally devised in software development. We implemented eight functionally distinct modules (request review, cost estimation, preauthorization, accessioning, prebilling, testing, reporting, and reimbursement consultation) and obtained feedback via an anonymous survey. We managed 50 clinical requests (January to June 2015). The fraction of pursued-to-requested cases (n = 15/50; utilization management fraction, 0.3) aimed for a high rate of preauthorizations. In 13 of 15 patients the insurance plan required preauthorization, which we obtained in 70% and ultimately achieved reimbursement in 50%. Interoperability enabled assessment of 12 different combinations of modules that underline the importance of an adaptive workflow and policy tailoring to achieve higher yields of reimbursement. The survey confirmed a positive attitude toward self-organizing teams. We acknowledge the individuals and their interactions and termed the infrastructure: human pipeline. Nontechnical barriers currently are limiting the scope and availability of clinical genomic sequencing. The presented human pipeline is one approach toward long-term financial sustainability of clinical genomics.

PURPOSE: Patients with cancers of oropharynx have a favorable prognosis and are an ideal candidate for adaptive therapy. A replan to improve coverage or escalate/de-escalate dose based on morphological information alone may not be adequate as the grossly involved lymph nodes (LNs) of a subset of these patients tend to become cystic and often do not regress. Functional adaptation may be a better approach when considering replanning for these patients. The purpose of this study was to evaluate the weekly trends in treatment related morphological and physiological changes for these LNs using diffusion-weighted MRI (DW-MRI) and evaluate its implications for adaptive replanning. METHODS: Ten patients with histologically proven oropharynx HNSCC undergoing concurrent chemoradiation were analyzed in this study. MR imaging protocol included axial T1w, T2w, and DW-MRI using a 3 T Philips MR scanner. The patients were scanned weekly in radiation treatment planning position using a 16 element phased-array anterior coil and a 44 element posterior coil. A total of 65 DWI and T2w scans were analyzed. DWI was performed using an optimized single-shot echo planar imaging sequence (TR/TE = 5000/65 ms, slice thickness = 5 mm; slices = 28; b values = 0 and 800 s/mm(2)). Quantification of the DW-MRI images was performed by calculating the apparent diffusion coefficient (ADC). T2w and DWI scans were imported into the Eclipse treatment planning system and gross tumor volumes (GTVs) corresponding to grossly involved LNs were contoured on each axial slice by physician experts. An attempt was made to remove any cystic or necrotic components so that the ADC analysis was of viable tumor only. A pixel-by-pixel fit of signal intensities within the GTVs was performed assuming monoexponential behavior. From each GTV histogram mean, median, standard deviation, skewness, and kurtosis were calculated. Absolute and percent change in weekly ADC histogram parameters and percent change in T2w GTV were also calculated. RESULTS: For all nodes, an immediate change in ADC was observed during first 2-3 weeks after which ADC values either continued to increase or plateaued. A few nodal volumes had a slightly decreased ADC value during later weeks. Percent increase in median ADC from weeks 1 to 6 with respect to baseline was 14%, 25%, 41%, 42%, 45%, and 58%. The corresponding change in median T2 volumes was 8%, 10%, 16%, 22%, 40%, and 42%, respectively. The ADC distribution of the viable tumors was initially highly kurtotic; however, the kurtosis decreased as treatment progressed. The ADC distribution also showed a higher degree of skewness in the first 2 weeks, progressively becoming less skewed as treatment progressed so as to slowly approach a more symmetric distribution. CONCLUSIONS: Physiological changes in LNs represented by changes in ADC evaluated using DW-MRI are evident sooner than the morphological changes calculated from T2w MRI. The decisions for adaptive replanning may need to be individualized and should be based primarily on tumor functional information. The authors' data also suggest that for many patients, week 3 maybe the optimal time to intervene and replan. Larger studies are needed to confirm their findings.

This paper examines the origins of consumerist discourse in health care from a communication perspective via a historical textual analysis of health writing in popular magazines from 1930 to 1949. The focus is on Consumers Union's Consumer Reports and the American Medical Association's lay health magazine, Hygeia. Findings from Consumer Reports show that the consumer movement of the 1930s-40s staunchly advocated for universal health insurance. Whereas consumer rights language nowadays tends towards individual choice and personal responsibility, consumerism in health care during that era articulated ideas about consumer citizenship, framing choice and responsibility in collectivist terms and health care as a social good. This paper also illuminates the limits and weaknesses of a central tenet in consumerism-freedom of choice-by analyzing stories in Hygeia about the doctor-patient relationship. A textual analysis finds that the AMA's justification in the 1930s-40s against socialized medicine, i.e., the freedom to choose a doctor, was in practice highly controlled by the medical profession. Findings show that long before the rhetoric of the "empowered consumer" became popular, some patients exercised some choice even in an era when physicians achieved total professional dominance. But these patients were few and tend to occupy the upper socioeconomic strata of US society. In reality choice was an illusion in a fee-for-service era when most American families could not afford the costs of medical care.

In 1990, Congress passed the Breast and Cervical Cancer Mortality Prevention Act because of increases in the number of low-income and uninsured women being diagnosed with breast cancer. This act authorized the Centers for Disease Control and Prevention (CDC) to establish the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) to provide high-quality and timely breast and cervical cancer screening and diagnostic services to low-income, uninsured women. The program started in 1991, and, in 1993, Congress amended the act to allow the CDC to fund American Indian and Alaska Native tribes and tribal organizations. By 1996, the program was providing cancer screening across the United States. To ensure appropriate delivery and monitoring of services, the program adopted detailed policies on program management, evidence-based guidelines for clinical services, a systematized clinical data system to track service quality, and key partnerships that expand the program's reach. The NBCCEDP currently funds 67 programs, including all 50 states, the District of Columbia, 5 US territories, and 11 tribes or tribal organizations.

Mouse models of eosinophilic disorders are often part of preclinical studies investigating the underlying biological mechanisms of disease pathology. The presence of extracellular eosinophil granule proteins in affected tissues is a well established and specific marker of eosinophil activation in both patients and mouse models of human disease. Unfortunately, assessments of granule proteins in the mouse have been limited by the availability of specific antibodies and a reliance on assays of released enzymatic activities that are often neither sensitive nor eosinophil specific. The ability to detect immunologically and quantify the presence of a mouse eosinophil granule protein in biological fluids and/or tissue extracts was achieved by the generation of monoclonal antibodies specific for eosinophil peroxidase (EPX). This strategy identified unique pairs of antibodies with high avidity to the target protein and led to the development of a unique sandwich ELISA for the detection of EPX. Full factorial design was used to develop this ELISA, generating an assay that is eosinophil-specific and nearly 10 times more sensitive than traditional OPD-based detection methods of peroxidase activity. The added sensitivity afforded by this novel assay was used to detect and quantify eosinophil degranulation in several settings, including bronchoalveolar fluid from OVA sensitized/challenged mice (an animal model of asthma), serum samples derived from peripheral blood recovered from the tail vasculature, and from purified mouse eosinophils stimulated ex vivo with platelet activating factor (PAF) and PAF + ionomycin. This ability to assess mouse eosinophil degranulation represents a specific, sensitive, and reproducible assay that fulfills a critical need in studies of eosinophil-associated pathologies in mice.

OBJECTIVE: To evaluate the effect of a patient panel-support tool (PST) on care delivery for diabetes mellitus (DM) and cardiovascular disease (CVD). STUDY DESIGN: Retrospective longitudinal cohort study among primary care providers (PCPs), with 2005 as the preintervention, 2006 as the implementation, and 2007 as the postintervention period. METHODS: We estimated the intervention effect using electronic medical record data and hierarchical linear models. The intervention was a PST displaying "care gaps" and recommendations for glycosylated hemoglobin, low-density lipoprotein cholesterol, and blood pressure screening and control; retinopathy, nephropathy, and foot screening; aspirin, statin, and angiotensin-converting enzyme inhibitor or beta-blocker use; and influenza and pneumococcal vaccination. Participants were qualifying PCPs and health maintenance organizations; patients. Patients had DM or CVD and 12 months of membership (n = 30,273 DM; 26,414 CVD). Main measures were mean percentages of care recommendations that were met by PCPs per patient per month (the care score). RESULTS: From 2005 to 2007, the mean care score (95% confidence interval) increased for both DM and CVD, from 63.5 (62.7, 64.3) to 70.6 (69.8, 71.4) and from 67.9 (67.2, 68.7) to 72.6 (71.9, 73.3), respectively. After adjustments, DM and CVD patients had improvements in the care score of 7.6 and 5.1, respectively, in 2007 compared with 2005 (P < .001). CONCLUSIONS: Delivery of care recommendations for DM and CVD improved after implementation of a PST. More research is necessary to optimize results and determine whether patient outcomes improve.

PURPOSE: To assess noninvasively the tumor microenvironment of neck nodal metastases in patients with head-and-neck cancer by investigating the relationship between tumor perfusion measured using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and hypoxia measured by (18)F-fluoromisonidazole ((18)F-FMISO) positron emission tomography (PET). METHODS AND MATERIALS: Thirteen newly diagnosed head-and-neck cancer patients with metastatic neck nodes underwent DCE-MRI and (18)F-FMISO PET imaging before chemotherapy and radiotherapy. The matched regions of interests from both modalities were analyzed. To examine the correlations between DCE-MRI parameters and standard uptake value (SUV) measurements from (18)F-FMISO PET, the nonparametric Spearman correlation coefficient was calculated. Furthermore, DCE-MRI parameters were compared between nodes with (18)F-FMISO uptake and nodes with no (18)F-FMISO uptake using Mann-Whitney U tests. RESULTS: For the 13 patients, a total of 18 nodes were analyzed. The nodal size strongly correlated with the (18)F-FMISO SUV (rho = 0.74, p < 0.001). There was a strong negative correlation between the median k(ep) (redistribution rate constant) value (rho = -0.58, p = 0.042) and the (18)F-FMISO SUV. Hypoxic nodes (moderate to severe (18)F-FMISO uptake) had significantly lower median K(trans) (volume transfer constant) (p = 0.049) and median k(ep) (p = 0.027) values than did nonhypoxic nodes (no (18)F-FMISO uptake). CONCLUSION: This initial evaluation of the preliminary results support the hypothesis that in metastatic neck lymph nodes, hypoxic nodes are poorly perfused (i.e., have significantly lower K(trans) and k(ep) values) compared with nonhypoxic nodes.

Today in the United States, outbreaks of vaccine-preventable disease are often traced to susceptible children whose parents have claimed an exemption from school or child care immunization regulations. The origins of this immunization hesitancy and resistance have roots in the decline of the threat of vaccine-preventable disease coupled with an increase in concerns about the adverse effects of vaccines, the emergence of mass media and the Internet, and the intrinsic limitations of modern medicine. Appeals to emotion have drowned out thoughtful discussion in public forums, and overall, public trust in immunizations has declined. We present an often overlooked behavior change strategy-social marketing-as a way to improve immunization rates by addressing the important roots of immunization hesitancy and effectively engaging emotions. As an example, we provide a synopsis of a social marketing campaign that is currently in development in Washington state and that is aimed at increasing timely immunizations in children from birth to age 24 months.
