Abstract
Short-term resource enrichment can increase species diversity in communities, but prolonged resource enrichment may result in either a diversity collapse or persistent high species diversity if fluctuation-dependent mechanisms of species coexistence are triggered. We tested the effects of resource enrichment on stream invertebrates by boosting densities of benthic detritus. In a 22-km stream length, we used wooden stakes to enhance retention of detritus at 40-m-long sites; other sites acted as controls. Detritus and invertebrates were sampled prior to treatment and then 1, 2, and 5 yr later. Previously, we reported that detrital densities, species diversity, and densities increased at enrichment sites after 12 months. Here we report that similar increases occurred 2 and 5 yr after manipulation. Prolonged resource enrichment produced persistently higher species diversity without loss of any taxa from the species pool, despite strong shifts in faunal composition in response to environmental variation, including a 1-in-100-yr flood. Detritus densities set upper limits to the densities of common taxa. Positive relations between invertebrate and detritus densities (density-resource relationships) took a variety of forms and showed that detritus was an essential resource for some taxa and a substitutable resource for others. Species varied in the minimum amount of detritus required for presence at a site, and population densities increased strongly from low densities when detritus was increased. These outcomes suggest that fluctuation-dependent mechanisms of coexistence enabled new taxa to coexist at manipulation sites, with relative nonlinear averaging of competition and the storage effect most likely to be in play. Two characteristics of the study stream underpin diversity increases with resource enrichment: overall low background densities of detritus and species that are able to disperse successfully from upstream areas where detritus is more abundant. Thus, the effects of resource enrichment are context dependent.

Abstract
Abstract
Background: EndoPredict has been previously validated as a prognostic test in women with ER-positive, HER2-negative disease who received endocrine therapy only as part of the ABCSG6 and -8 trials. Here, we further evaluate the prognostic value of EndoPredict in this cohort with longer-term follow-up and compare 10-year distant recurrence (DR) and 5-15 years late recurrence according to nodal status.
Methods: This analysis included 1702 patients with ER-positive, HER2-negative disease who received endocrine therapy only. Prognostic value of EPclin score and EPclin risk category (high, low) on the risk of distant recurrence adjusted for patient and disease characteristics was evaluated using multivariable Cox proportional hazard models. Kaplan-Meier estimators were used to estimate DR according EPclin class and were compared using log rank test. Analyses were performed for the overall cohort, by nodal status, and for patients who were distant recurrence free at year 5 (late recurrence).
Results: The median follow-up was 9.6 years (range 0-16.6), an increase of 4.2 years over previous reports. Reanalysis with longer follow-up confirms that EPclin is a significant predictor of DR after adjusting for clinical factors, regardless of nodal status (Table 1). Overall, 62.6% of patients had low risk EPclin scores and 10-year DR was significantly improved relative to those with high risk scores (p<0.0001; Table 2). When nodal status was considered, 77.8% of node negative tumors and 34.9% of node positive (1-3 PLN) tumors had low risk EPclin scores. Regardless of nodal status, DR was significantly improved for those with low versus high risk EPclin scores (Table 2). Similar results were observed for the patients who were DR free at year 5 (5-15 year follow-up) (Table 2).
Conclusion: This reanalysis of previous EndoPredict data with a longer follow-up confirms that EPclin can identify a large group of patients at low risk of distant recurrence after 10 years who might be sufficiently treated with 5 years adjuvant endocrine therapy only, independent of nodal status. Replication of these results for the late distant recurrence between years 5-15 also shows that EPclin scores may also be informative in selecting patients who may safely forgo extended endocrine therapy.

Abstract
The study of insect populations is dominated by research on terrestrial insects. Are aquatic insect populations different or are they just presumed to be different? We explore the evidence across several topics. (1) Populations of terrestrial herbivorous insects are constrained most often by enemies, whereas aquatic herbivorous insects are constrained more by food supplies, a real difference related to the different plants that dominate in each ecosystem. (2) Population outbreaks are presumed not to occur in aquatic insects. We report three examples of cyclical patterns; there may be more. (3) Aquatic insects, like terrestrial insects, show strong oviposition site selection even though they oviposit on surfaces that are not necessarily food for their larvae. A novel outcome is that density of oviposition habitat can determine larval densities. (4) Aquatic habitats are often largely 1-dimensional shapes and this is presumed to influence dispersal. In rivers, drift by insects is presumed to create downstream dispersal that has to be countered by upstream flight by adults. This idea has persisted for decades but supporting evidence is scarce. Few researchers are currently working on the dynamics of aquatic insect populations; there is scope for many more studies and potentially enlightening contrasts with terrestrial insects.

Abstract
Transoral laser microsurgery applies to the piecemeal removal of malignant tumours of the upper aerodigestive tract using the CO2 laser under the operating microscope. This method of surgery is being increasingly popularised as a single modality treatment of choice in early laryngeal cancers (T1 and T2) and occasionally in the more advanced forms of the disease (T3 and T4), predominantly within the supraglottis. Thomas Kuhn, the American physicist turned philosopher and historian of science, coined the phrase 'paradigm shift' in his groundbreaking book The Structure of Scientific Revolutions. He argued that the arrival of the new and often incompatible idea forms the core of a new paradigm, the birth of an entirely new way of thinking. This article discusses whether Steiner and colleagues truly brought about a paradigm shift in oncological surgery. By rejecting the principle of en block resection and by replacing it with the belief that not only is it oncologically safe to cut through the substance of the tumour but in doing so one can actually achieve better results, Steiner was able to truly revolutionise the management of laryngeal cancer. Even though within this article the repercussions of his insight are limited to the upper aerodigestive tract oncological surgery, his willingness to question other peoples' dogma makes his contribution truly a genuine paradigm shift.

Abstract
Abstract
Introduction: National guidelines recommend that women diagnosed with early-onset breast cancer and/or a strong family history receive BRCA1/2 testing to guide treatment decisions. Among newly diagnosed patients, a positive test result will often prompt more aggressive surgical treatment to minimize the risk of second primary cancers. Currently, coverage for genetic counseling and testing for Hereditary Breast and Ovarian Cancer (HBOC) under the Medicaid expansion program of the Affordable Care Act has varied by state, where some states require a copayment for this service. Similarly, there is no mandate to cover risk-reducing surgery for patients found to carry a genetic mutation despite research showing cost-effectiveness. This analysis sought to determine whether genetic testing for HBOC among patients with breast cancer is different for those with Medicaid compared to those with private insurance.
Methods: A commercial laboratory database was analyzed for patients with a personal history of breast cancer who underwent testing with a 25-gene hereditary cancer panel from September 2013-February 2016. Patients were eligible for inclusion if they were between ages 18 and 64 at the time of testing and had not undergone previous genetic testing. A total of 17,020 patients with either Medicaid (N=4,313) or one of 5 private payers (N=12,707) were tested during this period. Descriptive statistics, including means for continuous variables and proportions for categorical variables, were calculated. Chi-square tests were used to test associations and differences of positive rates between insurance provider category. Two-tailed p-values are reported, and any p-value less than 0.05 is considered statistically significant.
Results: Medicaid patients had a median age of breast cancer diagnosis of 45 compared to 47 for patient with private insurance. Among women with Medicaid insurance, a higher proportion were of African (13.3% vs 6.4%) and Latin American ancestry (16.4% vs 5.3%). The mutation positive rate among patients with Medicaid was 13.0%, which was statistically higher than patients with private insurance (9.5%) (p<0.001). The positive rate was higher among Medicaid patients of all ancestries suggesting that this discrepancy was not due to ancestry difference among the two testing populations.

Conclusions: Overall, the positive mutation rate among individuals with Medicaid insurance was higher than those with private insurance, suggesting the testing requirements applied to this population may be more stringent than those applied to the private insurance population. Consistent genetic testing insurance criteria are necessary for all patients to receive care in line with guidelines following a breast cancer diagnosis.

Abstract
OBJECTIVE The rapid worldwide rise in incidence of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) has generated studies confirming this disease as an entity distinct from traditional OPSCC. Based on pathology, surgical studies have revealed prognosticators specific to HPV-positive OPSCC. The current AJCC/UICC staging and pathologic nodal (pN)-classification do not differentiate for survival, demonstrating the need for new, HPV-specific OPSCC staging. The objective of this study was to define a pathologic staging system specific to HPV-positive OPSCC. METHODS Data were assembled from a surgically-managed, p16-positive OPSCC cohort (any T, any N, M0) of 704 patients from five cancer centers. Analysis was performed for (a) the AJCC/UICC pathologic staging, (b) newly published clinical staging for non-surgically managed HPV-positive OPSCC, and (c) a novel, pathology-based, "HPVpath" staging system that combines features of the primary tumor and nodal metastases. RESULTS A combination of AJCC/UICC pT-classification and pathology-confirmed metastatic node count (⩽4 versus ⩾5) yielded three groups: stages I (pT1-T2, ⩽4 nodes), II (pT1-T2, ⩾5 nodes; pT3-T4, ⩽4 nodes), and III (pT3-T4, ⩾5 nodes), with incrementally worse prognosis (Kaplan-Meier overall survival of 90%, 84% and 48% respectively). Existing AJCC/UICC pathologic staging lacked prognostic definition. Newly published HPV-specific clinical stagings from non-surgically managed patients, although prognostic, showed lower precision for this surgically managed cohort. CONCLUSIONS Three loco-regional "HPVpath" stages are identifiable for HPV-positive OPSCC, based on a combination of AJCC/UICC primary tumor pT-classification and metastatic node count. A workable, pathologic staging system is feasible to establish prognosis and guide adjuvant therapy decisions in surgically-managed HPV-positive OPSCC.

Abstract
Abstract
Background: Clinical diagnostic criteria for Li-Fraumeni syndrome (LFS) have evolved with increased utilization of TP53 germline testing and subsequent improved understanding of the diversity of the associated cancer phenotypes. However, data on LFS still suffer from ascertainment bias as patients are typically selected to undergo TP53 testing based on the presence of hallmark features of LFS. Analyzing TP53 mutation carriers identified from multi-gene panel testing, for which the diagnosis of LFS may not have been suspected or was included in a longer differential diagnosis, affords an opportunity to characterize additional TP53 carriers who might not otherwise have been ascertained.
Methods: Patients with a deleterious or suspected deleterious germline TP53 mutation were identified from 80,748 consecutive cases that underwent a 25-gene hereditary cancer panel test between September 2013 and March 2015 at a commercial diagnostic laboratory. Patient clinical data were obtained by healthcare provider report on test requisition forms. Each TP53 mutation carrier was evaluated to determine whether the National Comprehensive Cancer Network's (NCCN) guidelines were met for TP53 testing.
Results: Eighty-one TP53 mutation carriers were identified and had a total of 115 cancers (0.1% overall prevalence). Among the 76 carriers with at least one cancer, the average age at first diagnosis was 42 years (range 11-76 years) and 24% were first diagnosed older than age 50 years. The most common first cancers were of the breast (n=45), ovary (n=9), and gastrointestinal tract (n=8). Fifty-two of the 75 (69%) women had breast cancer, 44% of which were first diagnosed at 35 years or younger, and 21% were first diagnosed at 50 years or older. Only 27 TP53 carriers met NCCN criteria for TP53 testing, 14 of whom only met based on having early-onset breast cancer. An additional 8 did not meet criteria themselves but had a first- or second-degree relative who did. Among the 28 individuals with more than one primary cancer, 21 (75%) developed their second primary at a site for which increased surveillance is recommended in LFS, but only 4 would have met NCCN criteria for TP53 testing at their first cancer diagnosis. The most common second cancers were of the breast (n=16), gastrointestinal tract (n=4), or kidney (n=2) and occurred an average of 11 years after the first cancer (range 0-36 years).
Conclusion: In this analysis, a large proportion of carriers would not have been identified as TP53 testing candidates based on NCCN guidelines. Our data are consistent with other studies demonstrating high second primary cancer risks in LFS, and highlight the value of multigene panel testing in identifying individuals who may be candidates for increased surveillance and/or cancer risk-reducing management options.

Abstract
OBJECTIVE To describe the demographic and clinical characteristics of children and adolescents diagnosed with resistance to any anti-tuberculosis drug (drug-resistant tuberculosis; DR-TB) in South Africa. DESIGN We retrospectively reviewed medical records of all children (<13 years) and adolescents (13 to <18 years) with DR-TB at specialty hospitals in four South African provinces from 2005 to 2010. RESULTS During the review period, 774 children and adolescents (median age 11.3 years) were diagnosed with DR-TB at selected facilities. A high proportion of patients had a history of previous TB treatment (285/631; 45.2%), human immunodeficiency virus (HIV) infection (375/685; 54.7%), contact with a TB case (347/454; 76.4%), and smear-positive (443/729; 60.8%), cavitary (253/680, 38.7%) disease. Eighty-two per cent of patients with HIV infection received antiretroviral therapy. Of 626 patients diagnosed with multidrug-resistant TB (MDR-TB), 561 (89.6%) received a regimen consistent with national guidelines; the median length of treatment was 22 months (IQR 16-25). Among 400 patients with any DR-TB and a known outcome, 20.3% died during treatment. CONCLUSION Pediatric DR-TB in these provinces is characterized by complex clinical features at diagnosis, with one in five children dying during treatment. History of previous treatment and contact with a TB patient indicate opportunities for earlier diagnosis and treatment to improve outcomes.

Abstract
Introduction Pharyngoesophageal spasm (PES) can cause dysphagia, central valve leak (CVL), and dypshonia in post-laryngectomy patients. Botulinum toxin has been used effectively for the treatment of PES, but data regarding patient-reported outcomes and efficacy for CVL are limited. We evaluated the results of botox injection for PES spasm using subjective and objective measures. Methods Data were collected prospectively (February 2010 to August 2013) on 13 patients undergoing botox injection for PES as identified by video fluoroscopy. We collected digital voice recordings, air-pressure measurements (APMs) for speech, and quality of life (QoL) data before and after the procedure: University of Washington QoL questionnaire (UW-QoL), MD Anderson Swallowing Inventory (MDADI) and the Voice Handicap Index (VHI-30). Results APMs for a sustained vowel decreased by 18% after botox injection, whereas maximum phonatory times increased by 63% (mean increase, 8 to 13 seconds). Sustained vowel amplitude decreased (mean, 87db to 83db) with an associated reduction in sustained vowel frequency (117Hz to 77Hz). MDADI scores improved by 10.2% overall, and UW-QoL scores showed an improvement in score of 7.6%. Mean scores for VHI-30 deteriorated by 2% overall but, when considering only those patients experiencing dysphonia, an improvement of 9.4% was seen. There was an overall net reduction for the CVL cohort of 12 speech valves in the year after injection. Conclusions Our series confirm the safety and objective efficacy of botox injection for PES. QoL measurements were less convincing, and this disparity between subjective and objective measurements must be considered when treating such patients.

Abstract
We report a case of recurrent airway obstruction episodes resulting from laryngeal hypermobility in a patient with Ehlers-Danlos syndrome. A 44-year-old woman, with known Ehlers-Danlos syndrome, presented with recent onset of episodes of upper airway obstruction due to hypermobility of her larynx. A suitable conservative management strategy proved elusive and the patient finally underwent a thyrohyoidopexy. The patient remains symptom free nine months after the procedure. This is the first report of spontaneous life threatening upper airway obstruction due to hypermobility of the suprahyoid suspensory soft tissues in Ehlers-Danlos syndrome.

Abstract
Background and Purpose: We hypothesized that the P-selectin (SELP) gene, localized to a region on chromosome 1q24, pleiotropically contributes to increased blood pressure and cerebral atrophy. We tested this hypothesis by performing genetic correlation analyses for 13 mRNA gene expression measures from P-selectin and 11 other genes located in 1q24 region and three magnetic resonance imaging derived indices of cerebral integrity. Methods: The subject pool consisted of 369 (219F; aged 28–85, average = 47.1 ± 12.7 years) normally aging, community-dwelling members of large extended Mexican-American families. Genetic correlation analysis decomposed phenotypic correlation coefficients into genetic and environmental components among 13 leukocyte-based mRNA gene expressions and three whole-brain and regional measurements of cerebral integrity: cortical gray matter thickness, fractional anisotropy of cerebral white matter, and the volume of hyperintensive WM lesions. Results: From the 13 gene expressions, significant phenotypic correlations were only found for the P- and L-selectin expression levels. Increases in P-selectin expression levels tracked with decline in cerebral integrity while the opposite trend was observed for L-selectin expression. The correlations for the P-selectin expression were driven by shared genetic factors, while the correlations with L-selectin expression were due to shared environmental effects. Conclusion: This study demonstrated that P-selectin expression shared a significant variance with measurements of cerebral integrity and posits elevated P-selectin expression levels as a potential risk factor of hypertension-related cerebral atrophy.

Abstract
We examined age trajectories of fractional anisotropy (FA) of cerebral white matter (WM) and thickness of cortical gray matter (GM) in 1031 healthy human subjects (aged 11-90 years). Whole-brain FA and GM thickness values followed quadratic trajectories with age but the relationship between them was linear, indicating that a putative biological mechanism may explain the non-linearity of their age trajectories. Inclusion of the FA values into the quadratic model of the whole-brain and regional GM thickness changes with age made the effect of the age(2) term no longer significant for the whole-brain GM thickness and greatly reduced its significance for regional GM thickness measurements. The phylogenetic order of cerebral myelination helped to further explain the intersubject variability in GM thickness. FA values for the early maturing WM were significantly better (p=10(-6)) at explaining variability in GM thickness in maturing (aged 11-20) subjects than FA values for the late maturing WM. The opposite trend was observed for aging subjects (aged 40-90) where FA values for the late maturing WM were better (p=10(-16)) at explaining the variability in GM thickness. We concluded that the non-linearity of the age trajectory for GM thickness, measured from T1-weighted MRI, was partially explained by the heterogeneity and the heterochronicity of the age-related changes in the microintegrity of cerebral WM. We consider these findings as the evidence that the measurements of age-related changes in GM thickness and FA are driven, in part, by a common biological mechanism, presumed to be related to changes in cerebral myelination.

Abstract
Determining the time of peak of cerebral maturation is vital for our understanding of when cerebral maturation ceases and the cerebral degeneration in healthy aging begins. We carefully mapped changes in fractional anisotropy (FA) of water diffusion for eleven major cerebral white matter tracts in a large group (831) of healthy human subjects aged 11-90. FA is a neuroimaging index of micro-structural white matter integrity, sensitive to age-related changes in cerebral myelin levels, measured using diffusion tensor imaging. The average FA values of cerebral white matter (WM) reached peak at the age 32 ± 6 years. FA measurements for all but one major cortical white matter tract (cortico-spinal) reached peaks between 23 and 39 years of age. The maturation rates, prior to age-of-peak were significantly correlated (r=0.74; p=0.01) with the rates of decline, past age-of-peak. Regional analysis of corpus callosum (CC) showed that thinly-myelinated, densely packed fibers in the genu, that connect pre-frontal areas, maturated later and showed higher decline in aging than the more thickly myelinated motor and sensory areas in the body and splenium of CC. Our findings can be summarized as: associative, cerebral WM tracts that reach their peak FA values later in life also show progressively higher age-related decline than earlier maturing motor and sensory tracts. These findings carry multiple and diverse implications for both theoretical studies of the neurobiology of maturation and aging and for the clinical studies of neuropsychiatric disorders.

Abstract
We explored relationships between decline in cognitive processing speed (CPS) and change in frontal lobe MRI/MRS-based indices of cerebral integrity in 38 healthy adults (age 57-90 years). CPS was assessed using a battery of four timed neuropsychological tests: Grooved Pegboard, Coding, Symbol Digit Modalities Test and Category Fluency (Fruits and Furniture). The neuropsychological tests were factor analyzed to extract two components of CPS: psychomotor (PM) and psychophysical (PP). MRI-based indices of cerebral integrity included three cortical measurements per hemisphere (GM thickness, intergyral and sulcal spans) and two subcortical indices (fractional anisotropy (FA), measured using track-based spatial statistics (TBSS), and the volume of hyperintense WM (HWM)). MRS indices included levels of choline-containing compounds (GPC+PC), phosphocreatine plus creatine (PCr+Cr), and N-acetylaspartate (NAA), measured bilaterally in the frontal WM bundles. A substantial fraction of the variance in the PM-CPS (58%) was attributed to atrophic changes in frontal WM, observed as increases in sulcal span, declines in FA values and reductions in concentrations of NAA and choline-containing compounds. A smaller proportion (20%) of variance in the PP-CPS could be explained by bilateral increases in frontal sulcal span and increases in HWM volumes.

Abstract
CRA9508 Background: Addressing the impact of cancer treatment on fertility is a high priority in providing quality cancer care to patients of childbearing age. Evidence suggests less than 50% of patients receive adequate fertility information prior to cancer treatment. This study assessed the practice patterns of physicians and identified perceptions of barriers to communication about fertility. Methods: A 37 item survey was developed by a review of the literature and previous qualitative interviews. A random sample of physicians from the American Medical Association Masterfile was stratified by board specialty related to oncology. Three waves of surveys were distributed across the United States. The domains of the survey included demographics, knowledge, attitudes and practice behaviors related to FP with patients of childbearing age. Results: Of 1,979 physicians identified, a total of 613 physicians completed the survey, yielding a 33% response rate among oncologists. Oncologists with favorable attitudes towards FP were 4.9 times more likely to discuss the impact of cancer treatment on future fertility than those who have unfavorable attitudes. GYN or Medical/Hematological oncologists were 2.1 times more likely than other specialists to report feeling comfortable discussing FP with their patients. The majority of oncologists reported discussing FP with patients and indicated the primary barrier to discussion was a patient too ill to delay treatment. However, less than 25% of oncologists report referring patients for FP and only 38% report knowledge of the ASCO guidelines suggesting oncologists should discuss FP and refer all patients of childbearing age. Less than 25% of physicians surveyed reported distributing educational materials regarding FP. Conclusions: The majority of physicians in this survey report discussing FP; however they are not consulting specialists or providing educational materials to their patients. Future research will include the development of physician and nurse training curricula and interventions to facilitate discussion of FP between physicians and cancer patients. No significant financial relationships to disclose.

Abstract
UNLABELLED Pneumocystis jiroveci (formerly known as Pneumocystis carinii) is a fungal pathogen that causes pneumonia (PCP) in liver transplant recipients. Consequently, prophylaxis with trimethoprim-sulfamethoxazole (TMP/SMZ) is typically administered for at least 1 year at most liver transplant programs. At our center we have utilized a short-term (3-month) prophylactic regimen with TMP/SMZ for the past decade and report our experience and speculate on the potential widespread application of this approach. METHODS For patients transplanted at our center between January 1997 and January 2007, we recorded all documented PCP infections by review of our liver transplant database and hospital-based electronic medical records system, both of which record all infections and culture results. RESULTS We recorded no cases of PCP in any of the liver transplant recipients at our center during the study period. CONCLUSIONS We report the absence of PCP in a large cohort of liver transplant recipients receiving a short-term (3-month) prophylaxis with TMP/SMZ. These findings provide a rational basis to consider short-term (3-month) PCP prophylaxis or avoidance of prophylaxis altogether in selected low-risk patients.
