    To evaluate the personal and professional characteristics associated with career satisfaction and burnout among US oncologists. Between October 2012 and March 2013, the American Society of Clinical Oncology conducted a survey of US oncologists evaluating burnout and career satisfaction. The survey sample included equal numbers of men and women and represented all career stages. Of 2,998 oncologists contacted, 1,490 (49.7%) returned surveys (median age of respondents, 52 years; 49.6% women). Among the 1,117 oncologists (37.3% of overall sample) who completed full-length surveys, 377 (33.8%) were in academic practice (AP) and 482 (43.2%) in private practice (PP), with the remainder in other settings. Oncologists worked an average of 57.6 hours per week (AP, 58.6 hours per week; PP, 62.9 hours per week) and saw a mean of 52 outpatients per week. Overall, 484 oncologists (44.7%) were burned out on the emotional exhaustion and/or depersonalization domain of Maslach Burnout Inventory (AP, 45.9%; PP, 50.5%; P = .18). Hours per week devoted to direct patient care was the dominant professional predictor of burnout for both PP and AP oncologists on univariable and multivariable analyses. Although a majority of oncologists were satisfied with their career (82.5%) and specialty (80.4%) choices, both measures of career satisfaction were lower for those in PP relative to AP (all P career satisfaction is high among US oncologists, albeit lower for those in PP relative to AP. Burnout rates among oncologists seem similar to those described in recent studies of US physicians in general. Those oncologists who devote the greatest amount of their professional time to patient care seem to be at greatest risk for burnout.

  10. Bisphosphonate treatment recommendations for oncologists.

    Science.gov (United States)

    von Moos, Roger

    2005-01-01

    Renal safety is an important consideration for oncologists who are treating patients with bisphosphonates. In recent years, there has been increasing awareness about the development of bisphosphonate-induced nephrotoxicity. This has emerged mainly from increased clinical experience with zoledronic acid (Zometa); Novartis Pharmaceuticals Corporation, East Hanover, NJ, http://www.pharma.us.novartis.com). For this reason, the U.S. and European product labels for i.v. zoledronic acid were recently updated to include additional renal safety cautions, including dose adjustment in patients with mild-to-moderate renal impairment. However, renal toxicity is not a class effect. The product label for ibandronate (Bondronat), F. Hoffmann-La Roche Ltd., Basel, Switzerland, http://www.roche.com) has remained unchanged since the launch of the drug in the European Union in 2003. Ibandronate does not require mandatory monitoring of kidney function prior to each infusion. In addition, ibandronate can be used in patients with varying degrees of renal impairment. It also can be used without restrictions for nephrotoxic medications, and dose adjustment is only required in patients with severe renal impairment. Clinical implications of the renal safety of ibandronate include reducing the physician and nursing time needed for managing the adverse renal events associated with bisphosphonate therapy and dosing based on renal function. There also are no added renal safety risks and fewer inconvenient hospital visits with ibandronate therapy. In addition to i.v. ibandronate, an oral formulation of the drug is available. Oral ibandronate therapy is especially desirable because the medication is convenient (with a small, once-daily tablet that can be taken at home), reducing the health care costs associated with infusions. Clinical studies also indicate that 50 mg oral ibandronate has an efficacy similar to that of i.v. bisphosphonates and is associated with a low incidence of adverse

    2005-09-01

    There have been intensive debates about euthanasia and attempts to change laws on euthanasia in all countries. What doctors and particularly oncologists think about euthanasia must be taken into consideration, as their voices are crucial in this dialogue. The aim of this study was to find out how Turkish doctors approach euthanasia in the context of cancer. A questionnaire was used to collect data from 85 oncologists out of a total 800 in active oncology practice. Of the oncologists surveyed, 43.8% did not object to euthanasia. Some 33.7% had been asked to perform euthanasia and 41.5% believed that euthanasia was performed secretly although it is against the law in Turkey. Forty-two doctors (50.6%) noted that they had withdrawn treatment in patients. Doctors who encounter terminally ill patients with cancer should update their knowledge about patients' rights and euthanasia. Doctors, who are often asked to perform euthanasia, especially in the cancer setting, can help to illuminate the debates about euthanasia.

  18. Digestive oncologist in the gastroenterology training curriculum

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    Until the late 1980s, gastroenterology (GE) was consid-ered a subspecialty of Internal Medicine. Today, GE also incorporates Hepatology. However, Digestive Oncology training is poorly defined in the Hepatogastroenterology (HGE)-curriculum. Therefore, a Digestive Oncology cur-riculum should be developed and this document might be a starting point for such a curriculum. HGE-specialists are increasingly resisting the paradigm in which they play only a diagnostic and technical role in the manage-ment of digestive tumors. We suggest minimum end-points in the standard HGE-curriculum for oncology, and recommend a focus year in the Netherlands for Diges-tive Oncology in the HGE-curriculum. To produce well-trained digestive oncologists, an advanced Digestive Oncology training program with specific qualifications in Digestive Oncology (2 years) has been developed. The schedule in Belgium includes a period of at least 6 mo to be spent in a medical oncology department. The goal of these programs remains the production of well-trained digestive oncologists. HGE specialists are part of the multidisciplinary oncological teams, and some have been administering chemotherapy in their countries for years. In this article, we provide a road map for the organiza-tion of a proper training in Digestive Oncology. We hope that the World Gastroenterology Organisation and other (inter)national societies will support the necessary certi-fications for this specific training in the HGE-curriculum.

  19. The reality of economics for oncologists.

    2017-06-01

    This article outlines the historical development of health economics and its present role in oncology related health technology assessments (HTAs). Despite concerns about the prices and immediate costs of new anticancer medicines for indications such as breast cancer overall spending on such treatments is affordable and offers long term value for money in countries such as the US, Canada and those of Western Europe. Oncologists wishing to protect the interests of current and future patients with both advanced and earlier stage cancers may be regarded as having a responsibility to understand the nature of health economic evaluations, and to be actively involved in decisions affecting access to current treatments and future levels of investment in incrementally improving therapies.

    This is the first textbook of its kind devoted to describing the biological complexities of breast cancer in a way that is relevant to the radiation oncologist. Radiation Oncology has long treated breast cancer as a single biological entity, with all treatment decisions being based on clinical and pathologic risk factors. We are now beginning to understand that biological subtypes of breast cancer may have different risks of recurrence as well as different intrinsic sensitivity to radiotherapy. Multi-gene arrays that have for years been used to predict the risk of distant recurrence and the value of systemic chemotherapy may also have utility in predicting the risk of local recurrence. Additionally, the targeted agents used to treat breast cancer may interact with radiotherapy in ways that can be beneficial or undesirable. All of these emerging issues are extensively discussed in this book, and practical evidence-based treatment recommendations are presented whenever possible.

    The cancer anorexia-cachexia syndrome (CACS) is considered a multifactorial syndrome that leads a general decline of the cancer patient conditions, prognosis and survival, and characterized by progressive loss of body mass and functional impairment, due to marked energy metabolism imbalance and immunological disorders. It is the cause of death in almost one out of five advanced cancer patients. CACS is also accompanied with loss of quality of life, reduced response and tolerance to anticancer therapies and affected outcome. This condition arises by acute-chronic inflammation, hypercatabolism and resulting in an increased energy expenditure, anorexia and negative caloric balance. Although the international scientific community has reached some important findings in last years regarding CACS, a precise definition agreement for CACS in order to a precise patients assessment is still lacking. In light of the advances in pathogenesis and evaluation of CACS, as well as those reached in the therapy, this review aims to draft a list of key points that could be useful for the oncologist to recognize the different signs and symptoms of this syndrome, in order to evaluate and stage the cancer patients in attempt to target an early multimodal pharmacological-nutritional treatment strategy to improve his outcome and his quality of life.

  6. The Ghost Tradition: Helen Of Troy In The Elizabethan Era

    Directory of Open Access Journals (Sweden)

    RADUCANU ADRIANA

    2014-12-01

    Full Text Available Reputedly the most beautiful woman who has ever lived, Helen of Troy (or Sparta is less well known for her elusive, ghost-like dimension. Homer wrote that the greatest war of Western classical antiquity started because of Helen's adultery followed by her elopement to Troy. Other ancient writers and historians, among theme Aeschylus, Stesichorus, Hesiod, Pausanias, Aristophanes, Euripides and Gorgias of Leontini, challenged the Homeric version, in various ways and attempted to exonerate Helen either by focusing on her phantom/ ghost/ as the generic object of man's desire and scorn or by casting doubt on the mechanisms of the blaming process. This paper argues that the Elizabethans Christopher Marlowe and William Shakespeare adopted and adapted the anti-Homer version of the depiction of Helen, what I here call “the ancient Helen ghost tradition”; nevertheless, in so doing they further reinforced the character's demonic features and paradoxically achieved a return to the adulterous Homeric Helen.

    Oncotype DX (ODX), a tumor gene profiling test, has been incorporated into clinical guidelines to aid in adjuvant chemotherapy decision making for early-stage, hormone receptor positive breast cancer patients. Despite United States (U.S.) guidelines, less than half of eligible women receive testing. Reasons for low usage are unclear: Our objective was to better understand U.S. oncologists' ODX uptake and how they use ODX during adjuvant chemotherapy decision making. We conducted semi-structured, ~30-minute phone interviews with medical and surgical oncologists in one U.S. State using purposive sampling. Oncologists were included if they saw greater than or equal to five breast cancer patients per week. Recruitment ended upon thematic saturation. Interviews were recorded, transcribed, and double-coded using template analysis. During analysis, themes emerged across three domains. First, organizational factors (i.e., departmental structure, ODX marketing, and medical/insurance guidelines) influenced ease of ODX use. Second, oncologists referenced the influence of interpersonal factors (e.g., normative beliefs and peer use of ODX) over their own practices and recommendations. Third, intrapersonal factors (e.g., oncologist attitudes, perceived barriers, and research gaps) were discussed: although oncologists largely held positive attitudes about ODX, they reported challenges with interpreting intermediate scores for treatment decisions and explaining test results to patients. Finally, oncologists identified several research gaps. As more tumor gene profiling tests are incorporated into cancer care for treatment decision making, it is important to understand their use in clinical practice. This study identified multi-level factors that influence ODX uptake into clinical practice, providing insights into facilitators and modifiable barriers that can be leveraged for improving ODX uptake to aid treatment decision making.

    This research examined pediatric oncologists coping strategies when their patients died of cancer. Twenty-one pediatric oncologists at 2 Canadian pediatric academic hospitals were interviewed about their coping strategies when patients died or were in the process of dying. The grounded theory method of data collection and data analysis were used. Line-by-line coding was used to establish codes and themes and constant comparison was used to establish relations among emerging codes and themes. Pediatric oncologists used engagement coping strategies with primary and secondary responses including emotional regulation (social support and religion), problem solving (supporting families at end of life), cognitive restructuring (making a difference and research), and distraction (breaks, physical activity, hobbies and entertainment, spending time with own children). They also used disengagement coping strategies that included voluntary avoidance (compartmentalization and withdrawing from families at end of life). Given the chronic nature of patient death in pediatric oncology and the emotionally difficult nature of this work, medical institutions such as hospitals have a responsibility to assist pediatric oncologists in coping with this challenging aspect of their work. Future research is needed to evaluate how best to implement these changes on the institutional level to help oncologists cope with patient death and the effect of using these strategies on their quality of life.

    Helen Dodson Prince, a pioneer in the observation of solar flares, a pioneer in women's rise in the profession of astronomy, and a respected and revered educator of future astronomers, died on 4 February 2002 in Arlington, Virginia. Helen Dodson was born in Baltimore, Maryland, on 31 December 1905. Her parents were Helen Walter and Henry Clay Dodson. Helen went to Goucher College in nearby Towson with a full scholarship in mathematics. She turned to astronomy under the influence of a legendary teacher, Professor Florence P. Lewis, and she graduated in 1927. Funded by grants and private charity, she earned the Ph.D. in astronomy at the University of Michigan under the direction of Heber Doust Curtis in 1933. Dodson taught at Wellesley College from 1933 until 1943, when she went on leave to spend the last three years of World War II at the MIT Radiation Laboratory. She returned to Goucher after the war as professor of astronomy and mathematics, and in 1947 she came back to Michigan both as professor of astronomy and staff member of the McMath-Hulbert Observatory, of which she became associate director. In 1976 she retired from Michigan and spent her later years in Alexandria, Virginia. In 1932 Dodson held the Dean Van Meter fellowship from Goucher; in 1954 she received the Annie Jump Cannon Prize from the AAS; and in 1974 The University of Michigan honored her with its Faculty Distinguished Achievement Award. She published over 130 articles, mostly on her research specialty, solar flares. Dodson's interest in the Sun began at Michigan, although her dissertation was, like so many Michigan dissertations of the era, on stellar spectroscopy, "A Study of the Spectrum of 25 Orionis." She came to Michigan during the establishment and growth of the solar observatory at Lake Angelus, the creation of three gifted and industrious amateurs. Heber Curtis fostered the growth of the McMath-Hulbert enterprise and brought it into the University. Dodson's solar activity grew as a

This study was designed to explore China's oncologists' knowledge, attitudes and clinical practices regarding CAM use by their patients. An online survey was conducted of China's oncologists. Among 11,270 participants who completed the online survey, 6,007 (53.3%) were identified as oncologists. Most were men (75.2%), with a mean age of 33.4 (standard deviation: 6.5) years. The 6,007 oncologists discussed with 36.5% of their patients about CAM. Most of them (75.6%) did not want to initiate discussions due to lack of knowledge on CAM. Oncologists estimated that 40.0% of their patients used CAM treatments. Oncologists reported that 28.7% of their patients underwent anticancer therapy with the concurrent use of CAM. Four out of five of the responding oncologists self-reported inadequate knowledge and only 22.0% reported receiving professional education on CAM. Nearly half (44.9%) of the oncologists believed CAM treatment was effective for symptoms and treatment of cancer. Physician factors associated with initiating discussions with patients about CAM use included sex, age (≥ 33 years), medical license for traditional Chinese medicine, enough knowledge and professional education experience. China's oncologists infrequently discussed with their patients about CAM due to lack of knowledge. Most of the oncologists did not encourage CAM use.

    This research aimed to analyze the patterns of co-authorship network among the Korean radiation oncologists and to identify attributing factors for the formation of networks. A total of 1,447 articles including contents of 'Radiation Oncology' and 'Therapeutic Radiology' were searched from the KoreaMed database. The co-authorship was assorted by the author's full name, affiliation and specialties. UCINET 6.0 was used to figure out the author's network centrality and the cluster analysis, and KeyPlayer 1.44 program was used to get a result of key player index. Sociogram was analyzed with the Netdraw 2.090. The statistical comparison was performed by a t-test and ANOVA using SPSS 16.0 with p-value articles written by a radiation oncologist as the first author was 1,025 out of 1,447. The pattern of co-authorship was classified into five groups. For articles of which the first author was a radiation oncologist, the number of single-author articles (type-A) was 81; single-institution articles (type-B) was 687; and multiple-author articles (type-C) was 257. For the articles which radiation oncologists participated in as a co-author, the number of single-institution articles (type-D) was 280 while multiple-institution articles (type-E) were 142. There were 8,895 authors from 1,366 co-authored articles, thus the average number of authors per article was 6.51. It was 5.73 for type-B, 6.44 for type-C, 7.90 for type-D, and 7.67 for type-E (p = 0.000) in the average number of authors per article. The number of authors for articles from the hospitals published more than 100 articles was 7.23 while form others was 5.94 (p = 0.005). Its number was 5.94 and 7.16 for the articles published before and after 2001 (p = 0.000). The articles written by a radiation oncologist as the first author had 5.92 authors while others for 7.82 (p = 0.025). Its number was 5.57 and 7.71 for the Journal of the Korean Society for Therapeutic Radiology and Oncology and others (p = 0.000), respectively

    A number of medical smartphone applications have been developed to assist clinical oncology specialists. Concerns have arisen that the information provided may not be under sufficient scrutiny. This study aims to analyse the current applications available for clinical oncologists in the UK. Applications aimed specifically at physician clinical oncologists were searched for on the major smartphone operating systems: Apple iOS; Google Android; Microsoft Windows OS; and Blackberry OS. All applications were installed and analysed. The applications were scrutinised to assess the following information: cost; whether the information included was referenced; when the information was last updated; and whether they made any reference to UK guidelines. A novel rating score based on these criteria was applied to each application. Fifty applications were identified: 24 for Apple's iOS; 23 for Google's Android; 2 for Blackberry OS; and 1 for Windows OS. The categories of applications available were: drug reference; journal reference; learning; clinical calculators; decision support; guidelines; and dictionaries. Journal reference and guideline applications scored highly on our rating system. Drug reference application costs were prohibitive. Learning tools were poorly referenced and not up-to-date. Smartphones provide easy access to information. There are numerous applications devoted to oncology physicians, many of which are free and contain referenced, up-to-date data. The cost and quality of drug reference and learning applications have significant scope for improvement. A regulatory body is needed to ensure the presence of peer-reviewed, validated applications to ensure their reliability.

  19. A Balanced Approach to Physician Responsibilities: Oncologists' Duties toward Themselves.

    Although critical to the provision of best patient care, physician self-care is an underattended aspect of responsibility in the medical professions, including oncology. Neglecting self-care bears negative consequences for the individual oncologist, ranging from burnout and fatigue to interpersonal and relationship stress, addiction, and disruptive behavior. It may also contribute to medical errors, disinterest in or depersonalization of patient care, and lower quality of care. Because of its effect on physicians, patients, and the health care environment, physician self-care is increasingly recognized as an important professional responsibility. Nonetheless, professional obligations, competing demands on time, and personal priorities conspire to prevent a large proportion of oncologists from adequately attending to self-care in even simple ways, such as getting sufficient exercise and sleep. This chapter discusses the need for physician self-care and the repercussions of not meeting this fundamental responsibility. Self-care is described in the context of three life domains: professional, personal (physical, psychological, mental, and spiritual), and interpersonal (relationships, family, social, and community). Strategies are provided for caring for the self in each domain.

Quelles sont ses propres options poétiques et théoriques, telles qu’elles apparaissent dans les poèmes du recueil Intimates (2005 ? Et qu’a-t-elle pu hériter du féminisme poétique, de poètes tels que M. Rukeyser ou K. Clanchy ? Farish établit sa propre identité poétique, celle d’une jeune femme du XXIème siècle en train de faire la double découverte du langage et du monde, explorant en même temps certaines facettes de la sexualité féminine. A l’aide d’éléments tirés de sources aussi diverses épistémologiquement que la tradition romantique, la réflexion sur le sujet de Nancy K.

    Burnout in health care professionals could have serious negative consequences on quality of patient care, professional satisfaction and personal life. Our aim was to investigate the burnout prevalence, work and lifestyle factors potentially affecting burnout amongst European oncologists ≤40 (YOs). A survey was conducted using the validated Maslach Burnout Inventory (MBI) and additional questions exploring work/lifestyle factors. Statistical analyses were carried out to identify factors associated with burnout. Total of 737 surveys (all ages) were collected from 41 European countries. Countries were divided into six regions. Results from 595 (81%) YOs were included (81% medical oncologists; 52% trainees, 62% women). Seventy-one percent of YOs showed evidence of burnout (burnout subdomains: depersonalization 50%; emotional exhaustion 45; low accomplishment 35%). Twenty-two percent requested support for burnout during training and 74% reported no hospital access to support services. Burnout rates were significantly different across Europe (P Burnout was highest in central European (84%) and lowest in Northern Europe (52%). Depersonalization scores were higher in men compared with women (60% versus 45% P = 0.0001) and low accomplishment was highest in the 26-30 age group (P burnout factors (P burnout survey in European Young Oncologists. Burnout is common amongst YOs and rates vary across Europe. Achieving a good work/life balance, access to support services and adequate vacation time may reduce burnout levels.

    Full Text Available Interruptions are causal factors in medication errors. Although researchers have assessed the nature and frequency of interruptions during medication administration, there has been little focus on understanding their effects during medication ordering. The goal of this research was to examine the nature, frequency, and impact of interruptions on oncologists' ordering practices. Direct observations were conducted at a Canadian cancer treatment facility to (1 document the nature, frequency, and timing of interruptions during medication ordering, and (2 quantify the use of coping mechanisms by oncologists. On average, oncologists were interrupted 17 % of their time, and were frequently interrupted during safety-critical stages of medication ordering. When confronted with interruptions, oncologists engaged/multitasked more often than resorting to deferring/blocking. While some interruptions are necessary forms of communication, efforts must be made to reduce unnecessary interruptions during safety-critical tasks, and to develop interventions that increase oncologists' resiliency to inevitable interruptions.

    Full Text Available INTRODUCTION: Burnout syndrome which is prevalent among oncologists is characterized by three aspects: emotional exhaustion, depersonalization and low personal accomplishment. The purpose was to evaluate prevalence of the burnout syndrome among Brazilian medical oncologists and the variables that correlate with its presence. METHODS: A survey was conducted with members of the Brazilian Society of Medical Oncology (SBOC who received three questionnaires (general, Maslach burnout questionnaire and an opinion survey mailed to all 458 members. RESULTS: Response rate was of 22.3%. According to the criteria proposed by Grunfeld, which consider burnout present when at least one of the aspects is severely abnormal, prevalence of this syndrome was 68.6% (95% confidence interval, CI: 58.68% to 77.45%. By multivariate analysis having a hobby/physical activity, a religious affiliation, older age, living with a companion and rating vacation time as sufficient were correlated significantly and independently with burnout syndrome. CONCLUSIONS: The burnout syndrome is prevalent among Brazilian oncologists. Oncologists having sufficient personal and social resources to engage in a hobby, physical activity, have enough vacation time and religious activities are at lower risk of developing burnout.INTRODUÇÃO: A Síndrome da Estafa Profissional (SEP é considerada uma doença caracterizada por três componentes básicos: exaustão emocional (EE, despersonalização (DP e reduzida realização pessoal (RP, sendo identificada em oncologistas.

    Triple negative breast cancers (TNBCs) represent a distinct subgroup of breast cancers with an immunohistochemical phenotype that is negative for oestrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2). The aim of this article is to provide a broad overview of recent developments in the diagnosis and management of TNBC for surgical oncologists. This overview discusses the subtypes of TNBC and the relationship between this type of breast cancer and the BRCA1 gene. In addition, the article explores recent advances in the treatment of TNBC from a surgical, radiation, and medical oncology point of view. Lastly, evolving therapeutic strategies that have potential to enhance outcomes for patients with TNBC are also discussed.

    Trust in the oncologist is crucial for breast cancer patients. It reduces worry, enhances decision making, and stimulates adherence. Optimal nonverbal communication by the oncologist, particularly eye contact, body posture, and smiling, presumably benefits patients' trust. We were the first to experimentally examine (1) how the oncologist's nonverbal behavior influences trust, and (2) individual differences in breast cancer patients' trust. Analogue patients (APs) viewed one out of eight versions of a video vignette displaying a consultation about chemotherapy treatment. All eight versions varied only in the oncologist's amount of eye contact (consistent vs. inconsistent), body posture (forward leaning vs. varying), and smiling (occasional smiling vs. no smiling). Primary outcome was trust in the observed oncologist (Trust in Oncologist Scale). 214 APs participated. Consistent eye contact led to stronger trust (β = -.13, p = .04). This effect was largely explained by lower educated patients, for whom the effect of consistent eye contact was stronger than for higher educated patients (β = .18, p = .01). A forward leaning body posture did not influence trust, nor did smiling. However, if the oncologist smiled more, he was perceived as more friendly (rs = .31, p nonverbal communication with breast cancer patients while simultaneously managing increased time pressure and computer use during the consultation.

    To evaluate satisfaction with work-life balance (WLB) and career plans of US oncologists. The American Society of Clinical Oncology conducted a survey of US oncologists evaluating satisfaction with WLB and career plans between October 2012 and March 2013. The sample included equal numbers of men and women from all career stages. Of 2,998 oncologists contacted, 1,490 (49.7%) returned surveys. From 1,117 oncologists (37.3% of overall sample) completing full-length surveys, we evaluated satisfaction with WLB and career plans among the 1,058 who were not yet retired. The proportion of oncologists satisfied with WLB (n = 345; 33.4%) ranked lower than that reported for all other medical specialties in a recent national study. Regarding career plans, 270 oncologists (26.5%) reported a moderate or higher likelihood of reducing their clinical work hours in the next 12 months, 351 (34.3%) indicated a moderate or higher likelihood of leaving their current position within 24 months, and 273 (28.5%) planned to retire before 65 years of age. Multivariable analyses found women oncologists (odds ratio [OR], 0.458; P Satisfaction with WLB and burnout were the strongest predictors of intent to reduce clinical work hours and leave current position on multivariable analysis. Satisfaction with WLB among US oncologists seems lower than for other medical specialties. Dissatisfaction with WLB shows a strong relationship with plans to reduce hours and leave current practice. Given the pending US oncologist shortage, additional studies exploring interactions among WLB, burnout, and career satisfaction and their impact on career and retirement plans are warranted.

    The specialty of radiation oncology has experienced significant workforce planning challenges in many countries. Our purpose was to develop and validate a workforce-planning model that would forecast the balance between supply of, and demand for, radiation oncologists in Canada over a minimum 10-year time frame, to identify the model parameters that most influenced this balance, and to suggest how this model may be applicable to other countries. A forward calculation model was created and populated with data obtained from national sources. Validation was confirmed using a historical prospective approach. Under baseline assumptions, the model predicts a short-term surplus of RO trainees followed by a projected deficit in 2020. Sensitivity analyses showed that access to radiotherapy (proportion of incident cases referred), individual RO workload, average age of retirement and resident training intake most influenced balance of supply and demand. Within plausible ranges of these parameters, substantial shortages or excess of graduates is possible, underscoring the need for ongoing monitoring. Workforce planning in radiation oncology is possible using a projection calculation model based on current system characteristics and modifiable parameters that influence projections. The workload projections should inform policy decision making regarding growth of the specialty and training program resident intake required to meet oncology health services needs. The methods used are applicable to workforce planning for radiation oncology in other countries and for other comparable medical specialties. Copyright © 2012 Elsevier Ireland Ltd.

    Background Information in oncological consultations is often excessive. Those patients who better recall information are more satisfied, less anxious and more adherent. Optimal recall may be enhanced by the oncologist's non-verbal communication. We tested the influence of three non-verbal behaviors, i.e. eye contact, body posture and smiling, on patients' recall of information and perceived friendliness of the oncologist. Moreover, the influence of patient characteristics on recall was examined, both directly or as a moderator of non-verbal communication. Material and methods Non-verbal communication of an oncologist was experimentally varied using video vignettes. In total 194 breast cancer patients/survivors and healthy women participated as 'analog patients', viewing a randomly selected video version while imagining themselves in the role of the patient. Directly after viewing, they evaluated the oncologist. From 24 to 48 hours later, participants' passive recall, i.e. recognition, and free recall of information provided by the oncologist were assessed. Results Participants' recognition was higher if the oncologist maintained more consistent eye contact (β = 0.17). More eye contact and smiling led to a perception of the oncologist as more friendly. Body posture and smiling did not significantly influence recall. Older age predicted significantly worse recognition (β = -0.28) and free recall (β = -0.34) of information. Conclusion Oncologists may be able to facilitate their patients' recall functioning through consistent eye contact. This seems particularly relevant for older patients, whose recall is significantly worse. These findings can be used in training, focused on how to maintain eye contact while managing computer tasks.

    Oncologists in the US increasingly face the challenge of communicating with non-English speaking parents of children with cancer. This study explores this challenge from the perspectives of a sample of pediatric oncologists, interpreters, and Spanish-speaking parents of children with newly diagnosed leukemia. Thirty-seven oncologists and 17 professional language interpreters based at two non-profit pediatric hospitals in the US were surveyed on the topic of language barriers in pediatric care. Seventeen parents who communicated with their child's oncologist through an interpreter were also surveyed. All groups expressed considerable concern over the process of communicating across a language barrier. For oncologists, these concerns included the accuracy and completeness of interpretations, complexity of information, and loss of confidence and control over the communication process. For interpreters, they included complexity of information, information overload, and lack of clinician sensitivity toward the cultural and socioeconomic backgrounds of limited English proficiency (LEP) families. Parent concerns included difficulties comprehending information and anxiety over the possibility of missing out on important information. All groups provided multiple suggestions for improving communication across a language barrier. Oncologists, interpreters, and parents expressed considerable concern over the process of communicating across a language barrier. Some of these concerns could be minimized through efforts to boost interpreter accuracy and completeness, including the use of more simple, easy to understand language. Other issues, such as differences in culture and socioeconomic background, warrant consideration of the intercultural knowledge and skills of interpreters. (c) 2006 Wiley-Liss, Inc.

    Full Text Available Introduction: Discussion of bad news and resuscitation in terminal cancer is an important but difficult and often neglected issue in day-to-day oncology practice. Materials and Methods: We interviewed 35 radiation oncologists using an indigenous 15-item questionnaire on their beliefs about breaking bad news and resuscitation to terminal cancer patients. Results: Most responders had an oncology experience of three to seven years (20/35.Thirty-two were comfortable discussing cancer diagnosis, prognosis and life expectancy-related issues. A similar number believed all cancer-related information should be disclosed, while only four believed in imparting all information in one visit. All agreed that disclosing sensitive information did not affect survival. When requested by relatives to withhold truth from patients, 11 said they would not comply, 22 agreed to tell the truth only if asked and two agreed to avoid difficult questions. Twenty responders denied having been adequately trained in breaking bad news and were keen on dedicated classes or sessions in this area of practice. Most (33/35 believed that Indian patients were keen on knowing their diagnosis and prognosis. Although all agreed to the importance of discussing resuscitation, only 17 believed patients should be involved. Majority (20/35 agreed that the issue needs to be discussed while the patient was conscious. Patients with unsalvageable disease were deemed unsuitable for aggressive resuscitation by 30 responders while the rest believed it should be offered to all. Most (21/35 admitted to feeling depressed after breaking bad news though only seven felt disclosure was more stressful than untruthful statements. Only four knew of a law regarding resuscitation in cancer. Conclusion: Observing the widely varied beliefs and practices for disclosing bad news, it is recommended that such training be a regular part of medicine curriculum, especially in the Oncology setting.

    Communicating about the end of life with patients has been reported as one of the most difficult and stressful part of the work of oncologists. Despite this fact, oncologists receive little training in this area, and many do not communicate effectively with patients. The purpose of this analysis, part of a larger study examining oncologists' experiences of patient loss, was to explore oncologists' communication strategies and communication barriers when discussing end-of-life issues with patients. Twenty oncologists were interviewed at three hospitals about their communication strategies on end-of-life issues with patients. The data were analyzed using the grounded theory method. The findings revealed the strategies to effective communication about the end of life included: being open and honest; having ongoing, early conversations; communicating about modifying treatment goals; and balancing hope and reality. Barriers to implementing these strategies fell broadly into three domains, including physician factors, patient factors, and institutional factors. Physician factors included difficulty with treatment and palliation, personal discomfort with death and dying, diffusion of responsibility among colleagues, using the "death-defying mode," lack of experience, and lack of mentorship. Patient factors included, patients and/or families being reluctant to talk about the end of life, language barriers, and younger age. Institutional factors included stigma around palliative care, lack of protocol about end-of-life issues; and lack of training for oncologists on how to talk with patients about end-of-life issues. We conclude by drawing implications from our study and suggest that further research and intervention are necessary to aid oncologists in achieving effective communication about end-of-life issues.

    Full Text Available PURPOSE: There is no consensus on optimal use of radiotherapy following radical prostatectomy. The purpose of this study was to describe opinions of urologists and radiation oncologists regarding adjuvant and salvage radiotherapy following radical prostatectomy. METHODS: Urologists and genitourinary radiation oncologists were solicited to participate in an online survey. Respondent characteristics included demographics, training, practice setting, patient volume/experience, and access to radiotherapy. Participant practice patterns and attitudes towards use of adjuvant and salvage radiotherapy in standardized clinical scenarios were assessed. RESULTS: One hundred and forty-six staff physicians participated in the survey (104 urologists and 42 genitourinary radiation oncologists. Overall, high Gleason score (Gleason 7 vs. 6, RR 1.37 95% CI 1.19-1.56, p<0.0001 and Gleason 8-10 vs. 6, RR 1.56 95% CI 1.37-1.78, p<0.0001, positive surgical margin (RR 1.43 95% CI 1.26-1.62, p<0.0001, and extraprostatic tumour extension (RR 1.16 95% CI 1.05-1.28, p<0.002 conferred an increased probability of recommending adjuvant radiotherapy. Radiation oncologists were more likely to recommend adjuvant radiotherapy across all clinical scenarios (RR 1.48, 95% CI 1.39, 1.60, p <0.001. Major differences were found for patients with Gleason 6 and isolated positive surgical margin (radiotherapy selected by 21% of urologists vs. 70% of radiation oncologists, and patients with extraprostatic extension and negative surgical margins (radiotherapy selected by 18% of urologist vs. 57% of radiation oncologists. CONCLUSIONS: Urologists and radiation oncologists frequently disagree about recommendation for post-prostatectomy adjuvant radiotherapy. Since clinical equipoise exists between adjuvant versus early salvage post-operative radiotherapy, support of clinical trials comparing these approaches is strongly encouraged.

    Full Text Available Este artículo estudia las formas que asume el asentamiento de soldados en el mundo helenístico. En primer lugar, se estudia la época de Alejandro Magno en cuanto que precedente; en efecto, Alejandro ha utilizado en gran medida a sus soldados para fundar nuevas colonias, que son un medio de proteger y defender sus conquistas. Este procedimiento ha sido igualmente empleado por sus sucesores, los reyes helenísticos. Aquí estudio ante todo los reinos Seiéucida y Tolemaico, haciendo especial hincapié en los diferentes métodos de los que cada uno de ellos se ha servido, y los distintos fines que debía alcanzar cada una de sus respectivas políticas de asentamiento. Del mismo modo, en cada uno de los tres casos abordados me detengo ante todo en las relaciones entre macedonios, griegos, indígenas y no griegos en general en las nuevas fundaciones. Como conclusión, se resalta el sentido general de todo el proceso en la conformación del mundo helenístico.This paper analyzes the ways in which the settlement of soldiers has been accomplished in the Hellenistic world. Firstly, I study the age of Alexander the Great as a precedent; Alexander has greatly used his soldiers in the foundation of new colonies as a way to protect and defend his conquests. This procedure has been also used by his successors, the Hellenistic kings. I study mainly the Seleucid and the Ptolemaic Kingdoms, stressing the different ways each of them has used, and the different purposes of their different settiement politics. In the three cases deait the relations between Macedonians, Greeks, Natives and non-greeks in general in the new foundations are underlined. As a conclusión the overall meaning of all the process in the shaping of the Hellenistic worid is emphasized.

    The importance of the interplay between degassing and crystallization before and after the eruption of Mount St. Helens (Washington, USA) in 1980 is well established. Here, we show that degassing occurred over a period of decades to days before eruptions and that the manner of degassing, as deduced from geochemical signatures within the magma, was characteristic of the eruptive style. Trace element (lithium) and short-lived radioactive isotope (lead-210 and radium-226) data show that ascending magma stalled within the conduit, leading to the accumulation of volatiles and the formation of lead-210 excesses, which signals the presence of degassing magma at depth.

    Post-treatment cancer care is often fragmented and of suboptimal quality. We explored factors that may affect cancer survivors' post-treatment care coordination, including oncologists' use of electronic technologies such as e-mail and integrated electronic health records (EHRs) to communicate with primary care physicians (PCPs). We used data from a survey (357 respondents; participation rate 52.9%) conducted in 2012-2013 among medical oncologists caring for patients in a large US study of cancer care delivery and outcomes. Oncologists reported their frequency and mode of communication with PCPs, and role in providing post-treatment care. Seventy-five per cent said that they directly communicated with PCPs about post-treatment status and care recommendations for all/most patients. Among those directly communicating with PCPs, 70% always/usually used written correspondence, while 36% always/usually used integrated EHRs; telephone and e-mail were less used. Eighty per cent reported co-managing with PCPs at least one post-treatment general medical care need. In multivariate-adjusted analyses, neither communication mode nor intensity were associated with co-managing survivors' care. Oncologists' reliance on written correspondence to communicate with PCPs may be a barrier to care coordination. We discuss new research directions for enhancing communication and care coordination between oncologists and PCPs, and to better meet the needs of cancer survivors post-treatment.

    Purpose: The purpose of this study was to evaluate the variability in target volume and organ at risk (OAR) contour delineation for retroperitoneal sarcoma (RPS) among 12 sarcoma radiation oncologists. Methods and Materials: Radiation planning computed tomography (CT) scans for 2 cases of RPS were distributed among 12 sarcoma radiation oncologists with instructions for contouring gross tumor volume (GTV), clinical target volume (CTV), high-risk CTV (HR CTV: area judged to be at high risk of resulting in positive margins after resection), and OARs: bowel bag, small bowel, colon, stomach, and duodenum. Analysis of contour agreement was performed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: Ten radiation oncologists contoured both RPS cases, 1 contoured only RPS1, and 1 contoured only RPS2 such that each case was contoured by 11 radiation oncologists. The first case (RPS 1) was a patient with a de-differentiated (DD) liposarcoma (LPS) with a predominant well-differentiated (WD) component, and the second case (RPS 2) was a patient with DD LPS made up almost entirely of a DD component. Contouring agreement for GTV and CTV contours was high. However, the agreement for HR CTVs was only moderate. For OARs, agreement for stomach, bowel bag, small bowel, and colon was high, but agreement for duodenum (distorted by tumor in one of these cases) was fair to moderate. Conclusions: For preoperative treatment of RPS, sarcoma radiation oncologists contoured GTV, CTV, and most OARs with a high level of agreement. HR CTV contours were more variable. Further clarification of this volume with the help of sarcoma surgical oncologists is necessary to reach consensus. More attention to delineation of the duodenum is also needed.

    The well-being of oncologists is important to the well-being of their patients. While much is known about oncologist distress, little is known about oncologist well-being. We set out to evaluate oncologist well-being and the personal wellness promotion strategies used by oncologists. We performed a cross-sectional survey of medical oncologists in the North Central Cancer Treatment Group using a validated instrument to measure quality of life. Study-specific questions explored stressors, wellness promotion strategies and career satisfaction. Of 241 responding oncologists (response rate 61%), 121 (50%) reported high overall well-being. Being age 50 or younger (57 vs. 41%; p = 0.01), male (53 vs. 31%; p = 0.01) and working 60 h or less per week (50 vs. 33%; p = 0.005) were associated with increased overall well-being on bivariate analysis. Ratings of the importance of a number of personal wellness promotion strategies differed for oncologists with high well-being compared with those without high well-being. Developing an approach/philosophy to dealing with death and end-of-life care, using recreation/hobbies/exercise, taking a positive outlook and incorporating a philosophy of balance between personal and professional life were all rated as substantially more important wellness strategies by oncologists with high well-being (p values career satisfaction. Half of medical oncologists experience high overall well-being. Use of specific personal wellness promotion strategies appears to be associated with oncologist well-being. Further investigations of the prevalence, promotion, causes, inequities and clinical impact of physician well-being are needed. .

    Google is the most popular search engine in the United States, and patients are increasingly relying on online webpages to seek information about individual physicians. This study aims to characterize what patients find when they search for radiation oncologists online. The Centers for Medicare and Medicaid Services (CMS) Physician Comparable Downloadable File was used to identify all Medicare-participating radiation oncologists in the United States and Puerto Rico. Each radiation oncologist was characterized by medical school education, year of graduation, city of practice, gender, and affiliation with an academic institution. Using a custom Google-based search engine, up to the top 10 search results for each physician were extracted and categorized as relating to: (1) physician, hospital, or health care system; (2) third-party; (3) social media; (4) academic journal articles; or (5) other. Among all health care providers in the United States within CMS, 4443 self-identified as being radiation oncologists and yielded 40,764 search results. Of those, 1161 (26.1%) and 3282 (73.9%) were classified as academic and nonacademic radiation oncologists, respectively. At least 1 search result was obtained for 4398 physicians (99.0%). Physician, hospital, and health care-controlled websites (16,006; 39.3%) and third-party websites (10,494; 25.7%) were the 2 most often observed domain types. Social media platforms accounted for 2729 (6.7%) hits, and peer-reviewed academic journal websites accounted for 1397 (3.4%) results. About 6.8% and 6.7% of the top 10 links were social media websites for academic and nonacademic radiation oncologists, respectively. Most radiation oncologists lack self-controlled online content when patients search within the first page of Google search results. With the strong presence of third-party websites and lack of social media, opportunities exist for radiation oncologists to increase their online presence to improve patient-provider communication

    The increasing incidence of cancer is at the same time one of the leading causes of death all over the world. Many clinical studies show that the psychological disorders are more frequent in cancer patients than the normal population. That is the reason why "psycho-oncology" is getting popular each day. On the other hand, clinical studies about psychological status of the oncologists who are in contact with cancer patients ceaselessly and who are mostly responsible to give the "bad news" to the cancer patients are very limited. In fact, if the clinical studies which show that the frequency of depression and burnout syndrome are increasing among physicians are taken into consideration, one can say that psycho-oncology must cover all the medical personnel who are dealing with cancer patients. It is determined that the rate of depression and burnout syndrome is high among oncologists when referred to the literature. Several solutions are proposed for the psychological conditions of the oncologists and other related personnel who empathize with the patients and deliver "bad news" and also try to adopt ideal "patient-physician" communication model. The knowledge on the psychological conditions of oncology professionals and their behaviour and the results of the clinical studies on this subject will be discussed and the personal opinion will also be presented in this paper.

    To assess the occurrence of questions that foster shared decision making, in particular cancer patients' understanding of treatment decisions and oncologists' understanding of patients' priorities, during consultations in which preference-sensitive decisions are discussed. Specifically, (a) regarding patient understanding, do oncologists ask about patients' preexisting knowledge, information preferences, and understanding and do patients and companions ask about the disease and treatment, and (b) regarding patient priorities, do oncologists ask about patients' treatment- and decision-related preferences and do patients and companions ask about the decision? Audiotaped pretreatment consultations of 100 cancer patients with 32 oncologists about (neo)adjuvant treatment were coded and analyzed to document question type, topic, and initiative. The oncologists ascertained prior knowledge in 50 patients, asked 24 patients about preferred (probability) information, and invited questions from 56 patients. The oncologists asked 32 patients about treatment preferences and/or for consent. Respectively, one-third and one-fifth of patients and companions asked about treatment benefits compared with three-quarters of them who asked about treatment harms and/or procedures. It would be helpful to patients if oncologists more often assessed patients' existing knowledge to tailor their information provision. Also, patients could receive treatment recommendations that better fit their personal situation if oncologists collected information on patients' views about treatments. Moreover, by educating patients to ask about treatment alternatives, benefits, and harms, patients may gain a better understanding of the choice they have. Copyright © 2016 John Wiley & Sons, Ltd.

    The SEOM Future Plan is aimed at identifying the main challenges, trends and needs of the medical oncology speciality over the next years, including potential oncologist workforce shortages, and proposing recommendations to overcome them. The estimations of the required medical oncologists workforce are based on an updated Medical Oncologist Register in Spain, Medical Oncology Departments activity data, dedication times and projected cancer incidence. Challenges, needs and future recommendations were drawn from an opinion survey and an advisory board. A shortage of 211 FTE medical oncologist specialists has been established. To maintain an optimal ratio of 158 new cases/FTE, medical oncology workforce should reach 1881 FTE by 2035. Main recommendations to face the growing demand and complexity of oncology services include a yearly growth of 2.5% of medical oncologist's workforce until 2035, and development and application of more accurate quality indicators for cancer care and health outcomes measure.

    The picture of the 17th century, placed upon the great chimney in the "Salle des Actes", is attributed to the painter Simon Vouet or to his co-workers. It depicts a scene extracted from Odyssey by Homer. During their way-back to Greece, after the fall and the fire of Troia, Helen and Menelaus received in Egypt the famous nepenthes from the hands of Polydamna. An inventory of the possessions of the College of Pharmacy mentioned also helenium and moly. Nepenthes was really cited by Homer as a medicine used by Helen, but helenium was only related to Helen by euphony and moly referred to a totally different part of Odyssey and was not linked at all to Helen. This study points out the importance of mythology so far as origins of Pharmacy are concerned.

    To conduct a comprehensive analysis of supply of and demand for oncology services through 2020. This study was commissioned by the Board of Directors of ASCO. New data on physician supply gathered from surveys of practicing oncologists, oncology fellows, and fellowship program directors were analyzed, along with 2005 American Medical Association Masterfile data on practicing medical oncologists, hematologists/oncologists, and gynecologic oncologists, to determine the baseline capacity and to forecast visit capacity through 2020. Demand for visits was calculated by applying age-, sex-, and time-from-diagnosis-visit rate data from the National Cancer Institute's analysis of the 1998 to 2002 Surveillance, Epidemiology and End Results (SEER) database to the National Cancer Institute's cancer incidence and prevalence projections. The cancer incidence and prevalence projections were calculated by applying a 3-year average (2000-2002) of age- and sex-specific cancer rates from SEER to the US Census Bureau population projections released on March 2004. The baseline supply and demand forecasts assume no change in cancer care delivery and physician practice patterns. Alternate scenarios were constructed by changing assumptions in the baseline models. Demand for oncology services is expected to rise rapidly, driven by the aging and growth of the population and improvements in cancer survival rates, at the same time the oncology workforce is aging and retiring in increasing numbers. Demand is expected to rise 48% between 2005 and 2020. The supply of services provided by oncologists during this time is expected to grow more slowly, approximately 14%, based on the current age distribution and practice patterns of oncologists and the number of oncology fellowship positions. This translates into a shortage of 9.4 to 15.0 million visits, or 2,550 to 4,080 oncologists-roughly one-quarter to one-third of the 2005 supply. The baseline projections do not include any alterations based

    Cyclic behaviour on a range of timescales is a well-documented feature of many dome-forming volcanoes. Previous work on Soufrière Hills volcano (Montserrat) and Volcán de Colima (Mexico) revealed broad-scale similarities in behaviour implying the potential to develop general physical models of sub-surface processes [1]. Using volcano-seismic data from Mt St Helens (USA) and Mt Unzen (Japan) this study explores parallels in long-term behaviour of seismicity at two dome-forming systems. Within the last twenty years both systems underwent extended dome-forming episodes accompanied by large Vulcanian explosions or dome collapses. This study uses a suite of quantitative and analytical techniques which can highlight differences or similarities in volcano seismic behaviour, and compare the behaviour to changes in activity during the eruptive episodes. Seismic events were automatically detected and characterized on a single short-period seismometer station located 1.5km from the 2004-2008 vent at Mt St Helens. A total of 714 826 individual events were identified from continuous recording of seismic data from 22 October 2004 to 28 February 2006 (average 60.2 events per hour) using a short-term/long-term average algorithm. An equivalent count will be produced from seismometer recordings over the later stages of the 1991-1995 eruption at MT Unzen. The event count time-series from Mt St Helens is then analysed using Multi-taper Method and the Short-Term Fourier Transform to explore temporal variations in activity. Preliminary analysis of seismicity from Mt St Helens suggests cyclic behaviour of subannual timescale, similar to that described at Volcán de Colima and Soufrière Hills volcano [1]. Frequency Index and waveform correlation tools will be implemented to analyse changes in the frequency content of the seismicity and to explore their relations to different phases of activity at the volcano. A single station approach is used to gain a fine-scale view of variations in

    2007-02-01

    The ongoing activity of Mount St. Helens provides an opportunity to study the infrasonic wavefield produced by an active, silica-rich volcano. In late October 2004, as a pilot experiment for the Acoustic Surveillance for Hazardous Eruptions (ASHE) project, we deployed two infrasound arrays, each co-located with a broadband seismometer and weather station, to continuously record seismo-acoustic signals from Mount St. Helens. The nearest array, Coldwater, was deployed on the northern flank of the volcano, ˜ 13 km from the summit. The second array, Sacajawea, was deployed ˜ 250 km east of the volcano, at a distance where stratospherically ducted acoustic waves may be expected during the winter. This paper presents an overview of the experimental setup, and preliminary results from this unique data set. Eruptions on January 16th 2005 and March 9th 2005 produced strong infrasonic signals. The aseismic January 16th eruption signal lasted ˜ 9.4 min beginning at ˜ 11:20:44 01/16/05 UTC, while the March 9th eruption signal lasted ˜ 52.8 min beginning at ˜ 01:26:17 03/09/05 UTC, with the main steam and ash venting stage probably lasting ˜ 7.2 min. The March 9th signal was an order of magnitude larger than the January 16th signal, and was clearly recorded 250 km east at the Sacajawea array. Infrasonic expressions of long period (LP) seismic events ('drumbeats') have also been intermittently observed, and are recorded as acoustic waves mimicking the waveform and temporal sequence of their seismic counterparts. These acoustic observations provide important constraints for source models of long period events and eruptions.

    Industry-physician collaboration is critical for anticancer therapeutic development, but financial relationships introduce conflicts of interest. We examined the specialty variation and context of physician payments and ownership interest among oncologists. We performed a population-based multivariable analysis of 2014 Open Payments reports of industry payments to US physicians matched to physician and practice data, including sex, specialty, practice location, and sole proprietor status. Payment data were aggregated per physician and compared by specialty (medical, radiation, surgical, and nononcology), and practice location linked with spending level (low, average, and high). Primary outcomes included likelihood, mean annual amount, and number of general payments. Secondary outcomes included likelihood of holding ownership interests and receipt of royalty/license payments. Estimates for each outcome were determined using multivariable models, including logistic regression for likelihood and linear regression with gamma distribution and log-link for value, adjusted for physician specialty, sex, sole proprietor status, and practice spending. All statistical tests were two-sided. In 2014, there were 883 438 physicians, including 22 712 oncologists, licensed to practice in the United States. Among oncology specialties, 52.4% to 63.0% of physicians received a general payment in 2014, totaling $76 million, $4 million, and $5 million to medical, radiation, and surgical oncology, respectively. The median annual per-physician payment to medical oncologists was $632 (IQR = 136-2500), compared with $124 (IQR = 39-323) in radiation oncology and $250 (IQR = 84-1369) in surgical oncology. After controlling for physician and practice characteristics, oncologists were 1.09 to 1.75 times as likely to receive a general payment compared with nononcologists (overall P industry-oncologist financial relationships were common, and their impact on oncology practice should be further

    Physician burnout is associated with mental illness, alcohol abuse, and job dissatisfaction. Our objective was to estimate the impact of burnout on productivity of gynecologic oncologists during the first half of their career. A decision model evaluated the impact of burnout on total relative value (RVU) production during the first 15years of practice for gynecologic oncologists entering the workforce from 2011 to 2015. The SGO practice survey provided physician demographics and mean annual RVUs. Published data were used to estimate probability of burnout for male and female gynecologic oncologists, and the impact of depression, alcohol abuse, and early retirement. Academic productivity was defined as annual PubMed publications since finishing fellowship. Without burnout, RVU production for the cohort of 250 gynecologic oncologists was 26.2 million (M) RVUs over 15years. With burnout, RVU production decreased by 1.6 M (5.9% decrease). Disproportionate rates of burnout among females resulted in 1.1 M lost RVUs for females vs. 488 K for males. Academic production without burnout was estimated at 9277 publications for the cohort. Burnout resulted in 1383 estimated fewer publications over 15years (14.9%). The impact of burnout on clinical and academic productivity is substantial across all specialties. As health care systems struggle with human resource shortages, this study highlights the need for effective burnout prevention and wellness programs for gynecologic oncologists. Unless significant resources are designated to wellness programs, burnout will increasingly affect the care of our patients and the advancement of our field. Copyright © 2017 Elsevier Inc.

    2013-01-01

    Cancer in elderly patients is becoming a global issue, with the aging of the population and increased incidence of cancer with aging. Older patients with cancer have unique needs that can best be addressed by the integration of geriatrics principles and oncology care. Unfortunately, the worsening shortage of oncologists and geriatricians makes the care of the older patient with cancer increasingly challenging. Practical issues to consider when creating a geriatrics/oncology partnership include the available resources in terms of interdisciplinary team members, the patient population in need, and the ability to provide primary, consultative, and/or shared care. Ultimately, creative strategies will be needed to maximize the limited availability of the geriatrician and oncologist.

    International research shows that oncology staff suffers more from burnout than other healthcare professionals. Burnout is common among oncologists. The prevalence of emotional exhaustion, depersonalization, and low personal accomplishment appears to be significantly higher among physicians. Detecting burnout is highly relevant, because it affects the personal well-being and quality of life of the healthcare professional. A national study on the prevalence of burnout in oncology was never conducted in Flanders (Dutch-speaking part of Belgium). The Cédric Hèle institute spread anonymous questionnaires among 923 healthcare workers in oncology (physicians, social workers, psychologists, nurses, and specialist-nurses) in Flanders. The questionnaire consisted of two parts. The first part contained questions concerning demographic and job features. The second part included the Dutch version of the Maslach Burnout Inventory. Five hundred and fifty subjects participated in the survey (response rate of 59.5%). Of the medical oncologists, 51.2% suffered from emotional exhaustion, 31.8% from depersonalization, and 6.8% from a lack of personal accomplishment. Multivariate analysis of variance suggested a significantly elevated level of emotional exhaustion and depersonalization in oncologists compared with other professionals. Logistic regression indicated that the following variables have predictive value on risk of burnout: gender, profession, and combining work in a university hospital with work in a private hospital. The CHi research showed a significantly increased level of burnout-components in professionals working in oncology, especially in medical oncologists. These results should have an impact on the daily clinic of oncology, and could be guidance for further research. Copyright © 2014 John Wiley & Sons, Ltd.

    The purpose of this study was to understand oncology clinicians' perspectives about the care of advanced cancer patients following the completion of the ENABLE II (Educate, Nurture, Advise, Before Life Ends) randomized clinical trial (RCT) of a concurrent oncology palliative care model. This was a qualitative interview study of 35 oncology clinicians about their approach to patients with advanced cancer and the effect of the ENABLE II RCT. Oncologists believed that integrating palliative care at the time of an advanced cancer diagnosis enhanced patient care and complemented their practice. Self-assessment of their practice with advanced cancer patients comprised four themes: (1) treating the whole patient, (2) focusing on quality versus quantity of life, (3) “some patients just want to fight,” and (4) helping with transitions; timing is everything. Five themes comprised oncologists' views on the complementary role of palliative care: (1) “refer early and often,” (2) referral challenges: “Palliative” equals “hospice”; “Heme patients are different,” (3) palliative care as consultants or co-managers, (4) palliative care “shares the load,” and (5) ENABLE II facilitated palliative care integration. Oncologists described the RCT as holistic and complementary, and as a significant factor in adopting concurrent care as a standard of care.

    The families of oncology patients requiring intensive care often face increasing complexity in communication with their providers, particularly when patients are cared for by providers from different disciplines. To describe experiences and challenges faced by pediatric oncologists and intensivists and how the oncologist-intensivist relationship impacts communication and initiation of goals of care discussions (GCDs). We conducted semi-structured interviews with a convenience sample of ten physicians, including pediatric oncology and intensive care attendings and fellows. We identified key themes (3 barriers, 4 facilitators) to having GCDs with families of oncology patients who have received intensive care. Barriers included challenges to communication within teams because of hierarchy and between teams due to incomplete sharing of information and confusion about who should initiate GCDs; provider experiences of internal conflict about how to engage parents in decision making and about the "right thing to do" for patients; and lack of education and training in communication. Facilitators included team preparation for family meetings; skills for partnering with families; the presence of palliative care specialists; and informal education in communication and willingness for further training in communication. Notably, the education theme was identified as both a barrier and a resource. We identified barriers to communication with families both within and between teams and for individual physicians. Formal communication training and processes that standardize communication to ensure completeness and role delineation between clinical teams may improve oncologists' and intensivists' ability to initiate GCDs, thereby fulfilling their ethical obligations of decision support.

    This online survey of practising radiation oncologists from Korea, China and Japan was conducted to investigate the current practices in radiotherapy (RT) for spine metastasis and to compare these practices across the three countries. The questionnaire included nine general information questions and two clinical scenarios (representing ‘typical’ and ‘good’ prognosis spine metastasis), with seven questions for each scenario. An anonymous web-based survey using Google Docs® was undertaken from 2 September 2014 to 9 April 2015. A total of 54 Korean, 107 Chinese and 104 Japanese radiation oncologists participated in the study. The first scenario involved a typical case of spine metastasis (~25% expected 1-year survival rate), and the preferred fractionation scheme was 10 fractions of 3 Gy, though the pattern was slightly different in each country. The second scenario involved a good prognosis case (>50% expected 1-year survival rate), and 10 fractions of 3 Gy was the preferred practice in all three countries (however, use of a larger fraction dose with a smaller fraction number was more common in Korea). A more conformal RT technique was more prominent in China and Korea, especially for patients with a good prognosis. Avoidance of reirradiation was notable in China. In summary, a preference for multiple fractionation in RT for spine metastasis was observed in the majority of Korean, Chinese and Japanese radiation oncologists, although there were slight differences in practice preferences, especially for patients with a favorable prognosis.

    Although medical oncologists can have an important role in controlling the cost of cancer treatment, there is little information about their attitudes toward the cost of cancer treatment and the impact of cost on their treatment recommendations, especially in low- and middle-income countries (LMICs). In this study, we assessed the attitude of Iranian medical oncologists toward some economic aspects of new cancer drugs. We translated a questionnaire that was used in similar studies in the United States and Canada into Persian and modified it according to the local setting in Iran. The face and content validity of the questionnaire were assessed by oncologists before being used in the survey. We distributed the questionnaire and collected the data from 80 oncologists who participated in the 13th Annual Congress of the Iranian Society of Medical Oncology and Hematology (ISMOH). Fifty-two oncologists participated in our study (a response rate of 65%). The majority of oncologists stated that drug costs and patient out-of-pocket (OOP) costs influence their treatment recommendations (92% and 94%, respectively). Most oncologists (70%) felt that they are ready enough to use cost-effectiveness information in their treatment decisions, and 74% believed that patients should only have access to cancer treatments that are cost-effective. Most oncologists agree that the government should have control over drug prices, and more use of cost-effectiveness data is required for decision-making about cancer drug coverage. Ninety-one percent of oncologists said that they always or frequently discuss cancer treatment costs with their patients. Oncologists believed that academic groups (research centers and scientific societies) (81%) and the Ministry of Health (MoH) (43%) are the most eligible groups for determining whether a drug provides good value. Iranian medical oncologists are ready to participate in the health technology assessment and priority-setting process. This situation

  10. Impact on agriculture of the mount st. Helens eruptions.

    1981-01-02

    Ash from Mount St. Helens has fallen over a diverse agricultural area, with deposits of up to 30 kilograms per square meter. Crop losses in eastern Washington are estimated at about $100 million in 1980-about 7 percent of the normal crop value in the affected area and less than was expected initially. Production of wheat, potatoes, and apples will be normal or above normal because the favorable conditions for growth of these crops since the ashfall helped offset the losses. Alfalfa hay was severely lodged under the weight of the ash, but ash-contaminated hay is apparently nontoxic when eaten by livestock. The ash as an abrasive is lethal to certain insects, such as bees and grasshoppers, but populations are recovering. The ash has increased crop production costs by necessitating machinery repairs and increased tillage. On soil, the ash reduces water infiltration, increases surface albedo, and may continue to affect water runoff, erosion, evaporation, and soil temperature even when tilled into the soil. Ash on plant leaves reduced photosynthesis by up to 90 percent. Most plants have tended to shed the ash. With the possible exception of sulfur, the elements in the ash are either unavailable or present in very low concentrations; and no significant contribution to the nutrient status of soils is expected.

    The Magellan spacecraft orbited Venus from August 10, 1990, until it plunged into the Venusian atmosphere on October 12, 1994. Magellan Mission objectives included (1) improving the knowledge of the geological processes, surface properties, and geologic history of Venus by analysis of surface radar characteristics, topography, and morphology and (2) improving the knowledge of the geophysics of Venus by analysis of Venusian gravity. The Helen Planitia quadrangle (V-52), located in the southern hemisphere of Venus between lat 25 deg S. and 50 deg S. and between long 240 deg E. and 270 deg E., covers approximately 8,000,000 km2. Regionally, the map area is located at the southern limit of an area of enhanced tectonomagmatic activity and extensional deformation, marked by a triangle that has highland apexes at Beta, Atla, and Themis Regiones (BAT anomaly) and is connected by the large extensional belts of Devana, Hecate, and Parga Chasmata. The BAT anomaly covers approximately 20 percent of the Venusian surface.

    Eruptions can produce not only flows of incandescent material along the slopes of a volcano but also ash plumes in the troposphere [Sparks et al., 1997] that can threaten aircraft flying in the vicinity [Fisher et al., 1997]. To protect aircraft, passengers, and crews, the International Civil Aviation Organization and the World Meteorological Organization created eight Volcanic Ash Advisory Centers (VAAC, http://www.ssd.noaa.gov/VAAC/vaac.html) around the globe with the goal of tracking volcanic plumes and releasing eruption alerts to airports, pilots, and companies. Currently, the VAAC monitoring system is based mostly on the monitoring systems of any local volcano observatories and on real-time monitoring of data acquired by meteorological satellites. In the case of the 18 August 2000 eruption of the Miyakejima volcano in Japan, Houlié et al. [2005] showed that the Global Positioning System(GPS) might be used as an additional tool for monitoring volcanic plumes. The present article indicates that the 9 March 2005 eruption of Mount St. Helens, Washington, also produced detectable anomalies in GPS data.>

  15. Counting, accounting, and accountability: Helen Verran's relational empiricism.

    Science.gov (United States)

    Kenney, Martha

    2015-10-01

    Helen Verran uses the term 'relational empiricism' to describe situated empirical inquiry that is attentive to the relations that constitute its objects of study, including the investigator's own practices. Relational empiricism draws on and reconfigures Science and Technology Studies' traditional concerns with reflexivity and relationality, casting empirical inquiry as an important and non-innocent world-making practice. Through a reading of Verran's postcolonial projects in Nigeria and Australia, this article develops a concept of empirical and political 'accountability' to complement her relational empiricism. In Science and an African Logic, Verran provides accounts of the relations that materialize her empirical objects. These accounts work to decompose her original objects, generating new objects that are more promising for the specific postcolonial contexts of her work. The process of decomposition is part of remaining accountable for her research methods and accountable to the worlds she is working in and writing about. This is a practice of narrating relations and learning to tell better technoscientific stories. What counts as better, however, is not given, but is always contextual and at stake. In this way, Verran acts not as participant-observer, but as participant-storyteller, telling stories to facilitate epistemic flourishing within and as part of a historically located community of practice. The understanding of accountability that emerges from this discussion is designed as a contribution, both practical and evocative, to the theoretical toolkit of Science and Technology Studies scholars who are interested in thinking concretely about how we can be more accountable to the worlds we study.

    Women with recurrent ovarian cancer depend on their physicians to provide them with information about their diagnosis and available treatment options if they wish to participate in the process of choosing the treatment. There is no information on how oncologists give information to women during the physician-patient encounter at the time the disease recurs. To explore from the oncologists' perspective (i) the extent to which oncologists provide their own patients who are experiencing their first recurrence of ovarian cancer with the same information about management options, and (ii) any explicit or implicit criteria they use to decide whether and how to tailor the information to individual patients. We adopted a qualitative, exploratory descriptive approach to begin to understand oncologists' perspectives on how they gave information to patients within the context of their clinical practice. Individual interviews were used to identify themes related to the study objectives. Fifteen gynaecologic and five medical oncologists participated. Theme 1 describes the extent to which oncologists give information to their patients in the same way or in different ways. This section describes how the same oncologist may modify the depth of information transfer based on several factors. Theme 2 focuses on the factors that influence what information is given. For example, the amount and type of information given is based on the oncologist's on-going assessment of how the patient is assimilating the information shared during the medical encounter, the oncologists' perception of their relationship with the patient and the oncologist's assessment of what role they should take in decision making. Theme 3 involves the factors that influenced how information is given. For example, the information shared may vary based on the oncologist's perception of the patient's vitality, the patient's comprehension of the information, the patient's emotional well-being. In addition, the oncologist

    BACKGROUND Systematic symptom assessment is not routinely performed in pediatric oncology. The objectives of the current study were to characterize the symptoms of pediatric oncology outpatients and evaluate agreement between patient and proxy reports and the association between children’s ratings and oncologists’ treatment recommendations. METHODS Two versions of the pediatric Memorial Symptom Assessment Scale (pMSAS) were translated into Spanish. An age-appropriate and language-appropriate pMSAS was administered independently before visits to the oncologist to patients and family caregivers (caregivers) and after visits to consenting oncologists. Statistical analysis included Spearman correlation coefficients and weighted kappa values. RESULTS English and Spanish results were similar and were combined. A total of 60 children and their caregivers completed the pMSAS. The children had a median age of 10 years (range, 7–18 years); approximately 62% were male and 33% were Spanish-speaking. Fourteen oncologists completed the pMSAS for 25 patients. Nine patients (15%) had no symptoms and 38 patients (63%) reported ≥2 symptoms. The most common symptoms were fatigue (12 patients; 40%) and itch (9 patients; 30%) for the younger children and pain (15 patients; 50%) and lack of energy (13 patients; 45%) among the older children. Total and subscale score agreement varied by proxy type and subscale, ranging from fair to good for most comparisons. Agreement for individual symptoms between the patient and proxy ranged from a kappa of −0.30 (95% confidence interval, −0.43 to −0.01) to 0.91 (95% confidence interval, 0.75 to 1.00). Three of 51 symptomatic patients (6%) had treatment recommendations documented in the electronic health record. CONCLUSIONS Symptoms are common and cross several functional domains. Proxy and child reports are often not congruent, possibly explaining apparent undertreatment among this group of patients. PMID:26218240

    The aim of this study was to determine the attitude of Portuguese oncologists toward end-of-life situations other than euthanasia and assisted suicide. This study used a survey of 450 Portuguese oncologists by postal means and personal contact. The response rate was 33% (143). Only 7.7% doctors would give lethal doses of drugs to someone with an incurable, advanced, and progressive disease that is unable to make decisions, at the request of a family member or other close person. However, 30 doctors (21.3%) would prefer, in the event they were in such a situation, that the drugs be given them at their request. None of the 12.4% who have received such requests admitted to committing any of those acts. Almost 70% of the doctors would withdraw life support measures at the patient's request if the same had an incurable, advanced, and progressive disease, and a further 14% would do it in certain circumstances, but only 41% would withdraw measures such as nutrition and hydration. Fewer doctors would withdraw such measures including nutrition and hydration at a family member's request or on their own initiative. Religion has a major influence on the doctors' opinion. Most doctors (96.5%) agreed with the administration of drugs for symptom control even foreseeing that they could shorten life. Most Portuguese oncologists respect patients' autonomy, favoring the withdrawal of life support treatment at the patients' request when appropriate and much less do so on the request of others or by their own initiative. They appropriately do not confuse those practices with symptom relief even when hastened death can be envisaged.

    Full Text Available Immuno-oncology is a very popular field of medical science right now and developments on melanoma therapy have been absolutely marvelous for medical oncologists. Following these recent improvements, I remembered Irvin Yalom's novel “Schopenhauer Cure”. Because the book was narrating a psychotherapist who died from malignant melanoma. I think after all current innovations including BRAF, MEK inhibitors, and check point inhibitors, the novels' ‘end’ would be change. It is really exciting to have scientific developments that may change the end of the story in the book even though it is published less than ten years.

    Purpose: To perform a national survey of radiation oncologists and urologists about the type of resources used and the level of evidence needed to change clinical practice in localized prostate cancer. Methods and Materials: From a random sample, 1422 physicians were mailed a survey assessing the types of information used and what level of evidence could alter their clinical practice in prostate cancer. Multivariable logistic regression models were used to identify differences in physician characteristics for each outcome. Results: Survey response rates were similar for radiation oncologists and urologists (44% vs 46%; P=.46). Specialty-specific journals represented the most commonly used resource for informing the clinical practice for radiation oncologists (65%) and urologists (70%). Relative to radiation oncologists, urologists were less likely to report utilizing top-tier medical journals (25% vs 39%; adjusted odds ratio [OR] 0.50; P=.01) or cancer journals (22% vs 51%; adjusted OR 0.50; P<.001) but more likely to rely on clinical guidelines (46% vs 38%; adjusted OR 1.6; P=.006). Both radiation oncologists and urologists most commonly reported large randomized, clinical trials as the level of evidence to change treatment recommendations for localized prostate cancer (85% vs 77%; P=.009). Conclusions: Both specialties rely on their own specialty-specific journals and view randomized, clinical trials as the level of evidence needed to change clinical practice. Our study provides a context on meaningful ways of disseminating evidence for localized prostate cancer.

    Purpose While targeted sequencing improves outcomes for many cancer patients, how somatic and germline whole-exome sequencing (WES) will integrate into care remains uncertain. Methods We conducted surveys and interviews, within a study of WES integration at an academic center, to determine oncologists' attitudes about WES and to identify lung and colorectal cancer patients' preferences for learning WES findings. Results 167 patients (85% white, 58% female, mean age 60) and 27 oncologists (22% female) participated. Although oncologists had extensive experience ordering somatic tests (median 100/year), they had little experience ordering germline tests. Oncologists intended to disclose most WES results to patients but anticipated numerous challenges in using WES. Patients had moderately low levels of genetic knowledge (mean 4 correct of 7). Most patients chose to learn results that could help select a clinical trial, pharmacogenetic and positive prognostic results, and results suggesting inherited predisposition to cancer and treatable non-cancer conditions (all ≥95%). Fewer chose to receive negative prognostic results (84%) and results suggesting predisposition to untreatable non-cancer conditions (85%). Conclusion The majority of patients want most cancer-related and incidental WES results. Patients' low levels of genetic knowledge and oncologists' inexperience with large-scale sequencing presage challenges to implementing paired WES in practice. PMID:26866579

    Mount St Helens is the most active volcano within the Cascade arc; however, its location is unusual because it lies 50 km west of the main axis of arc volcanism. Subduction zone thermal models indicate that the down-going slab is decoupled from the overriding mantle wedge beneath the forearc, resulting in a cold mantle wedge that is unlikely to generate melt. Consequently, the forearc location of Mount St Helens raises questions regarding the extent of the cold mantle wedge and the source region of melts that are responsible for volcanism. Here using, high-resolution active-source seismic data, we show that Mount St Helens sits atop a sharp lateral boundary in Moho reflectivity. Weak-to-absent PmP reflections to the west are attributed to serpentinite in the mantle-wedge, which requires a cold hydrated mantle wedge beneath Mount St Helens (<∼700 °C). These results suggest that the melt source region lies east towards Mount Adams.

    Full Text Available

    Book 4 of Homer’s Odyssey contains two μύθοι (stories which reveal two, different “Helens”: the first “Helen” is a self-portrait, Helen tells her guests a story about her encounter with Odysseus at Troy. The second “Helen” is revealed in a counter story told straight after hers by her husband Menelaus. This counter tale reveals how Helen nearly succeeded in betraying the Greek soldiers hidden in the Trojan horse. In Helen’s story, she saves Odysseus’ life and her silence and complicity result in Trojan losses. In Menelaus’ story she threatens Odysseus’ life as well as those others hidden inside the Horse almost bringing about the downfall of the Greeks and the victory of the Trojans and thus reversing the outcome of the Trojan War.

    The questions to be asked are these: what is the purpose of these two portrayals of Helen? Indeed what is Helen doing in the Odyssey at all, after all, “The Iliad was Helen’s poem; the Odyssey is Penelope’s”?1 Why are we given this glimpse into the unquiet life of the reunited husband and wife and what does it portend, if anything, for the homecoming of Odysseus and his reunion with Penelope? This article examines the House of Sparta episode, and in particular its “Helen” stories, in an attempt to answer the above questions.

  11. Clast comminution during pyroclastic density current transport: Mt St Helens

    Volcanic clasts within pyroclastic density currents (PDCs) tend to be more rounded than those in fall deposits. This rounding reflects degrees of comminution during transport, which produces an increase in fine-grained ash with distance from source (Manga, M., Patel, A., Dufek., J. 2011. Bull Volcanol 73: 321-333). The amount of ash produced due to comminution can potentially affect runout distance, deposit sorting, the volume of ash lofted into the upper atmosphere, and increase internal pore pressure (e.g., Wohletz, K., Sheridan, M. F., Brown, W.K. 1989. J Geophy Res, 94, 15703-15721). For example, increased pore pressure has been shown to produce longer runout distances than non-comminuted PDC flows (e.g., Dufek, J., and M. Manga, 2008. J. Geophy Res, 113). We build on the work of Manga et al., (2011) by completing a pumice abrasion study for two well-exposed flow units from the May 18th, 1980 eruption of Mt St Helens (MSH). To quantify differences in comminution from source, sampling and the image analysis technique developed in Manga et al., 2010 was completed at distances proximal, medial, and distal from source. Within the units observed, data was taken from the base, middle, and pumice lobes within the outcrops. Our study is unique in that in addition to quantifying the degree of pumice rounding with distance from source, we also determine the possible range of ash sizes produced during comminution by analyzing bubble wall thickness of the pumice through petrographic and SEM analysis. The proportion of this ash size is then measured relative to the grain size of larger ash with distance from source. This allows us to correlate ash production with degree of rounding with distance from source, and determine the fraction of the fine ash produced due to comminution versus vent-fragmentation mechanisms. In addition we test the error in 2D analysis by completing a 3D image analysis of selected pumice samples using a Camsizer. We find that the roundness of PDC

    Family members (FMs) regularly attend cancer consultations with patients, may assume an array of roles (e.g. emotional, informational) and their involvement may result in benefits and/or challenges. Little is currently known about how oncology health professionals (HPs) view FMs who accompany a patient in consultations. This study aimed to explore the attitudes and practices of Australian oncologists and oncology nurses regarding family involvement in consultations. Eleven oncologists and 10 nurses from a range of subspecialties and tumour streams participated in semi-structured interviews. Interviews were transcribed and qualitatively analysed using framework analysis methods. Five relevant themes were identified: (1) the varied and dynamic nature of family roles during consultations; (2) positivity towards FMs; (3) the benefits of family involvement to the FM themselves; (4) current HP practices to facilitate positive family involvement; and (5) the challenges of family involvement in consultations and HP practices to manage them. Overall, participants held mostly positive attitudes towards family involvement. Although they identified a number of challenges which can arise when family are involved, many noted these situations are the exception, that there are strategies which can help to overcome the challenges, and that the benefits of family involvement typically outweigh the costs. © 2016 John Wiley & Sons Ltd.

    Pediatrics residents treat patients who are particularly vulnerable and they care for many patients in palliative situations. The purpose of this study was to build a typology detailing the representations of pediatrics and oncology residents on palliative care and how these transfer to their practice, and to determine their knowledge of euthanasia and end-of-life legislation. To draw up this typology, we used a semidirective interview method. The topics treated were their definition of palliative care, end of life, the emotions involved in these situations, and their daily practice. Then we asked them to speak about their opinions and knowledge of euthanasia and end-of-life legislation. Thirteen residents were interviewed: eight pediatrics residents, two oncologists, and three hemato-oncologists. Interviews lasted around 45min. Pediatrics and oncology residents had common representations based on "care giving." Nevertheless, pediatrics residents remained within the technical aspects to protect themselves from their negative emotions and stayed away from their patients. Oncology residents set their emotions aside to be able to carry on taking care of their patients. It seems necessary to disseminate a palliative culture, particularly in pediatrics, to improve management of children in palliative situations and to improve resident's feelings.

    Purpose. Recommendations for communicating bad or serious news are based on limited evidence. This study was designed to understand patient perspectives on what patients value when oncologists communicate news of cancer recurrence. Study Design and Methods. Participants were 23 patients treated for a gastrointestinal cancer at a tertiary U.S. cancer center within the past 2 years, who had semistructured qualitative interviews in which they listened to audio recordings of an oncology fellow discussing news of cancer recurrence with a standardized patient. Participants paused the audio recording to comment on what they liked or disliked about the oncologist's communication. Results. Three themes were identified that refine existing approaches to discussing serious news. The first theme, recognition, described how the oncologist responded to the gravity of the news of cancer recurrence for the patient. Participants saw the need for recognition throughout the encounter and not just after the news was given. The second theme, guiding, describes what participants wanted after hearing the news, which was for the oncologist to draw on her biomedical expertise to frame the news and plan next steps. The third theme, responsiveness, referred to the oncologist's ability to sense the need for recognition or guidance and to move fluidly between them. Conclusion. This study suggests that oncologists giving news of cancer recurrence could think of the communication as going back and forth between recognition and guidance and could ask themselves: “Have I demonstrated that I recognize the patient's experience hearing the news?” and “Have I provided guidance to the next steps?” PMID:21349951

    To evaluate the perceptions of the importance and utility of robot assisted surgery in gynecologic oncology. A 39 question web-based survey was sent to members of the Society of Gynecologic Oncologists. The survey response rate was 28%, with 277 surveys completed. Nearly 40% of respondents felt robotic surgical training was required as a part of their career goals, and 73% of respondents have performed a robotic hysterectomy. Among respondents, 39% felt that robotic surgery was as good as laparoscopic surgery but 23% thought robot assisted surgery should be the gold standard for the treatment of endometrial cancer. Robot assisted surgery is gaining widespread acceptance and is perceived to be as good as laparoscopic surgery for the treatment of early stage endometrial and cervical cancers. Among respondents the greatest benefit of robot assisted surgery was its ease of use and perceived improvement in a patient's quality of life. Copyright © 2010 John Wiley & Sons, Ltd.

    Immune checkpoint inhibitors (ICI) represent a new revolutionary weapon in the armamentarium of anti-cancer therapies. The side effects of these new agents represent a new challenge for oncologists; they are usually unpredictable and sometimes life threatening, if not managed rapidly and adequately. The most frequent side effects are the dermatologic, but they are usually low grade side effects and consequently easily manageable. Rash, pruritus and vitiligo are the most frequent dermatologic side effects. We aimed in this review to describe first all the dermatologic side effects of ICI according to the subtype of ICI and combination therapies in the clinical trials, then to report all the rare case reports dermatologic side effects, and finally to present the management algorithm of these side effects.

    The growing popularity and acceptance of integrative medicine is evident both among patients and among the oncologists treating them. As little data are available regarding health-care professionals' knowledge, attitudes, and practices relating to the topic, a nationwide online survey was designed. Over a period of 11 weeks (from July 15 to September 30, 2014) a self-administered, 17-item online survey was sent to all 676 members of the Research Group on Gynecological Oncology (Arbeitsgemeinschaft Gynäkologische Onkologie) in the German Cancer Society. The questionnaire items addressed the use of integrative therapy methods, fields of indications for them, advice services provided, level of specific qualifications, and other topics. Of the 104 respondents (15.4%) using integrative medicine, 93% reported that integrative therapy was offered to breast cancer patients. The second most frequent type of tumor in connection with which integrative therapy methods were recommended was ovarian cancer, at 80% of the participants using integrative medicine. Exercise, nutritional therapy, dietary supplements, herbal medicines, and acupuncture were the methods the patients were most commonly advised to use. There is considerable interest in integrative medicine among gynecological oncologists, but integrative therapy approaches are at present poorly implemented in routine clinical work. Furthermore there is a lack of specific training. Whether future efforts should focus on extending counseling services on integrative medicine approaches in gynecologic oncology or not, have to be discussed. Evidence-based training on integrative medicine should be implemented in order to safely guide patients in their wish to do something by themselves.

    For decades Western medicine has followed a biomedical model based on linear thinking and an individualized, disease-oriented doctor-patient relationship. Today this framework must be replaced by a biopsychosocial model based on complexity theory and a person-oriented medical team-patient relationship, taking into account the psychological and social determinants of health and disease. However, the new model is already proving no longer adequate or appropriate, and current events are urging us to develop an ecological model in which the medical team takes into account both individual illness and population health as a whole, since we are all part of the biosphere. In recent years, the rising costs of cancer treatment have raised a serious issue of economic sustainability. As the population of our planet, we now need to rapidly address this issue, and everyone of us must try to reduce their ecological footprint, measured as CO2 production. Medical oncologists need to reduce the ecological footprint of their professional activity by lowering the consumption of economic resources and avoiding environmental damage as much as possible. This new paradigm is endorsed by the Italian College of Hospital Medical Oncology Directors (CIPOMO). A working group of this organization has drafted the "Green Oncology Position Paper": a proposal of Italian medical oncology (in accordance with international guidelines) that oncologists, while aiming for the same end results, make a commitment toward the more appropriate management of health care and the careful use of resources in order to protect the environment and the ecosphere during the daily exercise of their professional activities.

    Background The fast growing demand and the shortage of resources are pushing toward more efficient models of survivorship care delivery. The Associazione Italiana di Oncologia Medica (AIOM) established an interdisciplinary working group with the purpose of promoting organizational improvements at the national level. A survey aimed at assessing attitudes and feelings of oncologists was considered preliminary to further initiatives. Methods A 25-item questionnaire, sent to the mailing list of the Society, explored the following issues on the practice of breast and colorectal cancer patients' follow up: 1) organization; 2) clinical features; 3) feelings about the different meanings of follow-up. Results Ninety-one oncologists of 160 institutions (57%) answered to the questionnaire. Although follow up is considered a distinct oncological activity in 68%, a fully shared organization between specialists is not common and communications with Primary Care Physicians are not structured in the majority of the cases. Fifty-five and 30% of the oncologists follow breast and colorectal cancer patients indefinitely. In case of discharge a survivorship care plan is delivered in only 9%. The majority of respondents do not hold a role of follow up in mortality reduction. Conclusions Although survivorship care represents a significant part of the oncologists' workload, an “oncology-centered” model is largely adopted and established care pathways are still incomplete. Survivorship care needs to be put at the center of an educational policy and of a widespread organizational effort, directed at improving appropriateness and quality. PMID:24983237

    To evaluate the satisfaction with work-life balance (WLB) and career satisfaction of gynecologic oncologists. In August 2014, members of the Society of Gynecologic Oncology (SGO) were sent an anonymous, cross-sectional survey evaluating demographic variables, practice characteristics, career satisfaction, fatigue, and satisfaction with WLB. Fatigue was assessed using a visual-analog scale. Career satisfaction and WLB were assessed with a Likert scale. Inferential statistics were computed with type I error rates of 0.05. Out of the 1002 gynecologic oncologists surveyed, 290 (28.9%) responded. Only 18.6% of respondents were satisfied with WLB and there were significant associations between gender (P = 0.0157), time spent in work related activities at home (P = 0.0024), on weekends (P = 0.0017), and in the hospital (P = 0.0001). More than 84% of physicians reported they would choose medicine as a career again and of those 90% would choose to be a gynecologic oncologist again. Fatigue was strongly associated with dissatisfaction with WLB in univariate and multivariate analysis (P careers, most are not satisfied with their WLB. Given the forecast shortage of gynecologic oncologists and projected increased cancer rates, understanding the factors associated with career satisfaction may assist the SGO in meeting future gynecologic cancer care needs.

    On December 11, 1989, geologists working in the crater at Mount St. Helens discovered two thin layers of ash separated by fresh snow-clear evidence that at least two small explosions had occurred recently. The explosions were neither seen nor heard, but on December 7 scientists suspected that a small ash-producing explosion had occurred when seismometers near the volcano recorded a long explosion-like signal, and titlt and displacement meters showed minor deformation of the dome. There were no other large seismic signals to account for the second ash layer, which was most likely associated with one of several smaller signals in early December. The December ash-producing explosions were the first eruptive activity at Mount St. Helens since October 1986.

    A large-amplitude traveling ionospheric disturbance (TID) was detected over Owens Valley, California, on May 18, 1980, by a highly sensitive very long baseline interferometry (VLBI) radio astronomy experiment. This TID is interpreted as the response of the ionosphere to a gravity wave excited in the neutral atmosphere by the explosion of Mount St. Helens that took place at 1532 UT on that day. A model, invoking the point-excitation of internal gravity waves in an isothermal atmosphere, which fits observations of the TID at several other stations, leads to identification of the features observed in the VLBI data. Small-amplitude higher-frequency changes in the ionosphere were detected for several hours after the passage of the large-amplitude Mount St. Helens TID, but it is not clear whether these were excited by the passage of the gravity wave or were background fluctuations.

    Interactions between breast cancer patients and their oncologists are important as effective patient-physician communication can facilitate the delivery of quality cancer care. However, little is known about patient-physician communication processes among Asian American breast cancer patients, who may have unique communication needs and challenges. Thus, we interviewed Asian American patients and several oncologists to explore patient-physician communication processes in breast cancer care. We conducted in-depth interviews with nine Chinese- or Korean American breast cancer patients and three Asian American oncologists who routinely provided care for Asian American patients in the Washington DC metropolitan area in 2010. We conducted patient interviews in Chinese or Korean and then translated into English. We conducted physicians' interviews in English. We performed qualitative analyses to identify themes. For women with limited English proficiency, language was the greatest barrier to understanding information and making treatment-related decisions. Both patients and oncologists believed that interpretation provided by patients' family members may not be accurate, and patients may neglect to ask questions because of their worry of burdening others. We observed cultural differences regarding expectations of the doctor's role and views of cancer recovery. As expressed by the patients and observed by oncologists, Asian American women are less likely to be assertive and are mostly reliant on physicians to make treatment decisions. However, many patients expressed a desire to be actively involved in the decision-making process. Findings provide preliminary insight into patient-physician communication and identify several aspects of patient-physician communication that need to be improved for Asian American breast cancer patients. Proper patient education with linguistically and culturally appropriate information and tools may help improve communication and decision

    Full Text Available Summary Introduction: Patients who are treating cancer have often used alternative therapies. In the internet era, information can be broadcasted widely, and this happened with phosphoethanolamine in Brazil, where this substance was claimed by the population to be the "cure for cancer." Method: This is a cross-sectional study developed by the Brazilian Society of Clinical Oncology (SBOC. An objectively structured questionnaire was sent by e-mail and SMS to active MDs members of the SBOC. Descriptive statistics was used to evaluate the data. Statistical significance between the variables was tested by Pearson's Chi-squared test (p<0.05 was considered significance. Results: The survey was sent to 1,072 oncologists, and 398 (37.1% answered at least part of it. One hundred and fifteen (28.9% had followed patients who had used phosphoethanolamine. Among these, 14 (12.2% observed adverse events and four (3.5% attributed clinical benefit to the substance. Most of the oncologists (n=331; 83.2% believe that it should only be used as part of a clinical trial protocol. Most physicians did not recommend this drug to their patients (n=311; 78.1%. Oncologists in Southeast, South and Midwest Brazil were more likely to have patients taking the drug compared to the Northern and Northeastern regions. Conclusion: This is the first survey to assess the opinion and experience of oncologists about this alternative therapy. Most oncologists in Brazil do not believe that synthetic phosphoethanolamine is active in cancer treatment, do not recommend its use without proper evaluation, and state that it should only be available to patients in the context of clinical trials.

  12. The Evolution and Role of the Saharan Air Layer During Hurricane Helene (2006)

    The Saharan air layer (SAL) has received considerable attention in recent years as a potential negative influence on the formation and development of Atlantic tropical cyclones. Observations of substantial Saharan dust in the near environment of Hurricane Helene (2006) during the National Aeronautics and Space Administration (NASA) African Monsoon Multidisciplinary Activities (AMMA) Experiment (NAMMA) field campaign led to suggestions about the suppressing influence of the SAL in this case. In this study, a suite of satellite remote sensing data, global meteorological analyses, and airborne data are used to characterize the evolution of the SAL in the environment of Helene and assess its possible impact on the intensity of the storm. The influence of the SAL on Helene appears to be limited to the earliest stages of development, although the magnitude of that impact is difficult to determine observationally. Saharan dust was observed on the periphery of the storm during the first two days of development after genesis when intensification was slow. Much of the dust was observed to move well westward of the storm thereafter, with little SAL air present during the remainder of the storm's lifetime and with the storm gradually becoming a category-3 strength storm four days later. Dry air observed to wrap around the periphery of Helene was diagnosed to be primarily non-Saharan in origin (the result of subsidence) and appeared to have little impact on storm intensity. The eventual weakening of the storm is suggested to result from an eyewall replacement cycle and substantial reduction of the sea surface temperatures beneath the hurricane as its forward motion decreased.

    This report describes a series of geoelectrical soundings carried out on and near Mount St. Helens volcano, Washington, in 2010–2011. These soundings used a controlled-source audio-frequency magnetotelluric (CSAMT) approach (Zonge and Hughes, 1991; Simpson and Bahr, 2005). We chose CSAMT for logistical reasons: It can be deployed by helicopter, has an effective depth of penetration of as much as 1 kilometer, and requires less wire than a Schlumberger sounding.

    A roughness spectrum allows surface structure to be interpreted as a sum of sinusoidal components with differing wavelengths. Knowledge of the roughness spectrum gives insight into the mechanisms responsible for electromagnetic scattering at a given wavelength. Measured spectra from 10-year-old primary debris flow surfaces at Mount St. Helens conform to a power-law spectral model, suggesting that these surfaces are scaling over the measured range of spatial frequencies. Measured spectra from water-deposited surfaces deviate from this model.

    The 1980 eruptions of Mount St. Helens in southeast Washington resulted in a pronounced effect on the surface and ground water resources of the state. In response to the volcanic activity, the U.S. Geological Survey intensified statewide surface and ground water sampling programs to determine the nature and magnitude of the volcanic-induced variations. Streams to the east of Mount St. Helens received the major ash fallout. Chemical effects were best noted in smaller streams sampled 60 to 70 miles northeast of Mount St. Helens. The chemical variations observed were pronounced but short lived. Sulfate and chloride increases in anionic composition were prevalent immediately following the eruption; however, the original bicarbonate predominance was again attained within several days. Suspended iron and aluminum concentrations were similarly elevated during the period of greatest ash deposition (highest turbidity); however, the dissolved concentrations remained relatively constant. Depressions of pH were minor and short lived. Streams draining to the south, tributaries to the Columbia river, showed little observable changes in water chemistry. Streams draining to the west (Toutle river and its tributaries) were compositionally affected by the various volcanic activities. Chloride and sulfate anion percentage exceeded the bicarbonate percentage up to one month following the eruption period. Streams and lakes sampled in the immediate vicinity of Mount St. Helens, in addition to trace metals, contained organic compounds derived from decomposing wood buried in the debris deposits. This organic material may constitute a significant source of organic compounds to surface and ground water for some time to come.

    Mount St. Helens seized the world’s attention in 1980 when the largest historical landslide on Earth and a powerful explosive eruption reshaped the volcano, created its distinctive crater, and dramatically modified the surrounding landscape. An enormous lava dome grew episodically in the crater until 1986, when the volcano became relatively quiet. A new glacier grew in the crater, wrapping around and partly burying the lava dome. From 1987 to 2003, sporadic earthquake swarms and small steam explosions indicated that magma (molten rock) was being replenished deep underground. In 2004, steam-and-ash explosions heralded the start of another eruption. A quieter phase of continuous lava extrusion followed and lasted until 2008, building a new dome and doubling the volume of lava on the crater floor. Scientists with the U.S. Geological Survey and University of Washington’s Pacific Northwest Seismograph Network maintain constant watch for signs of renewed activity at Mount St. Helens and other Cascade volcanoes. Now is an ideal time for both actual and virtual visitors to Mount St. Helens to learn more about dramatic changes taking place on and beneath this active volcano.

    This study was conducted to investigate the current role of medical oncologists in cancer care with a focus on increasing the recognition of medical oncology as an independent specialty. Questionnaires modified from the Medical Oncology Status in Europe Survey dealing with oncology structure, resources, research, and patterns of care given by medical oncologists were selected. Several modifications were made to the questionnaire after feedback from the insurance and policy committee of the Korean Association for Clinical Oncology (KACO). The online survey was then sent to KACO members. A total of 214 medical oncologists (45.8% of the total inquiries), including 71 directors of medical oncology institutions, took the survey. Most institutions had various resources, including a medical oncology department (94.1%) and a department of radiation oncology (82.4%). There was an average of four medical oncologists at each institution. Medical oncologists were involved in various treatments from diagnosis to end-of-life care. They were also chemotherapy providers from a wide range of institutions that treated many types of solid cancers. In addition, 86.2% of the institutions conducted research. This is the first national survey in Korea to show that medical oncologists are involved in a wide range of cancer treatments and care. This survey emphasizes the contributions and proper roles of medical oncologists in the evolving health care environment in Korea.

It was motivated by the high potential of detecting and targeting oncogenic drivers. Recognizing that the diffusion of diagnostic tests is a conditio sine qua non for the success of personalized lung cancer therapies, this study analyzed the diffusion of epidermal growth factor receptor (EGFR and anaplastic lymphoma kinase (ALK tests in Germany. Qualitative and quantitative research strategies were combined in a mixed-method design. A literature review and subsequent Key Opinion Leader interviews identified a set of qualitative factors driving the diffusion process, which were then translated into an online survey. The survey was conducted among a sample of 961 oncologists (11.34% response rate. The responses were analyzed in a multiple linear regression which identified six statistically significant factors driving the diffusion of molecular diagnostic lung cancer tests: reimbursement, attitude towards R&D, information self-assessment, perceived attitudes of colleagues, age and test-pathway strategies. Besides the important role of adequate reimbursement and relevant guidelines, the results of this study suggest that an increasing usage of test-pathway strategies, especially in an office-based setting, can increase the diffusion of molecular diagnostic lung cancer tests in the future.

    Full Text Available Abstract Background The current educational environment may need enhancement to tackle the rising cancer burden in India. The aim of this study was to conduct a survey of Surgical Oncologists to identify their perceptions of the current state of Oncology education in India. Methods An Institutional Review Board approved questionnaire was developed to target the audience of the 2009 annual meeting of the Indian Association of Surgical Oncology in India. The survey collected demographic information and asked respondents to provide their opinions about Oncology education in India. Results A total of 205 out of 408 attendee's participated in the survey with a 42.7% response rate. The majority of respondents felt that Oncology education was poor to fair during medical school (75%, residency (56% and for practicing physicians (71%. The majority of participants also felt that the quality of continuing medical education was poor and that minimal emphasis was placed on evidence based medicine. Conclusions The results of our survey demonstrate that the majority of respondents feel that the current educational environment for Oncology in India should be enhanced. The study identified perceptions of several gaps and needs, which can be the targets for implementing measures to enhance the training of Oncology professionals.

    The objective of this study was to survey the use of reirradiation (Re-RT) for in-field failures after previous radical radiation treatment (RT) among Canadian radiation oncologists (ROs). An electronic survey was sent to 271 ROs in Canada. The completed surveys were received electronically via e-mail and the data were analyzed using SAS 9.1.3 software. A total of 183 ROs (67.5%) completed and returned the survey. The majority of the respondents were involved in the practice of either breast (48%) or genitourinary (43%) tumor sites. A total of 49% of the participants were interested in using Re-RT for the management of in-field recurrences. The goals of the therapy would be improvement of quality of life (99%), locoregional control (80%), or cure (32%). Most of the physicians believed that patients should have a minimum Karnofsky performance status of 50 or Eastern Cooperative Oncology Group performance status of 3, a minimum life expectancy of 3 months, and a minimum interval from initial treatment of 3 months if Re-RT were to be given with curative intent. This survey showed that a wide variation existed among ROs in their approach to Re-RT. Newer technologies in RT planning and delivery would be employed to facilitate normal tissue avoidance. The results of this study suggested that a consensus meeting was needed to establish guidelines for the practice and prospective evaluation of Re-RT.

  8. Oncologist use of the Adjuvant! model for risk communication: a pilot study examining patient knowledge of 10-year prognosis

    2009-04-01

    Full Text Available Abstract Background Our purpose was to collect preliminary data on newly diagnosed breast cancer patient knowledge of prognosis before and after oncology visits. Many oncologists use a validated prognostic software model, Adjuvant!, to estimate 10-year recurrence and mortality outcomes for breast cancer local and adjuvant therapy. Some oncologists are printing Adjuvant! screens to use as visual aids during consultations. No study has reported how such use of Adjuvant! printouts affects patient knowledge of prognosis. We hypothesized that Adjuvant! printouts would be associated with significant changes in the proportion of patients with accurate understanding of local therapy prognosis. Methods We recruited a convenience sample of 20 patients seen by 2 senior oncologists using Adjuvant! printouts of recurrence and mortality screens in our academic medical center. We asked patients for their estimates of local therapy recurrence and mortality risks and counted the number of patients whose estimates were within ± 5% of Adjuvant! before and after the oncology visit, testing whether pre/post changes were significant using McNemar's two-sided test at a significance level of 5%. Results Two patients (10% accurately estimated local therapy recurrence and mortality risks before the oncology visit, while seven out of twenty (35% were accurate afterwards (p = 0.125. Conclusion A majority of patients in our sample were inaccurate in estimating their local therapy recurrence and mortality risks, even after being shown printouts summarizing these risks during their oncology visits. Larger studies are needed to replicate or repudiate these preliminary findings, and test alternative methods of presenting risk estimates. Meanwhile, oncologists should be wary of relying exclusively on Adjuvant! printouts to communicate local therapy recurrence and mortality estimates to patients, as they may leave a majority of patients misinformed.

    Geographic access to care may be associated with receipt of chemotherapy but has not been fully examined. This study sought to evaluate the association between density of oncologists and travel distance and receipt of adjuvant chemotherapy for colon cancer within 90 days of colectomy. Patients in the National Cancer Data Base with stage III colon cancer, diagnosed between 2007 and 2010, and age 18 to 80 years were selected. Generalized estimating equation clustering by hospital service area was conducted to examine the association between geographic access and receipt of oncology services, controlling for patient sociodemographic and clinical characteristics. Of 34,694 patients in the study cohort, 75.7% received adjuvant chemotherapy within 90 days of colectomy. Compared with travel distance less than 12.5 miles, patients who traveled 50 to 249 miles (odds ratio [OR], 0.87; P=.009) or ≥250 miles (OR, 0.36; P<.001) had decreased likelihood of receiving adjuvant chemotherapy. Density level of oncologists was not statistically associated with receipt of adjuvant chemotherapy (low v high density: OR, 0.98; P=.77). When stratifying analyses by insurance status, non-privately insured patients who resided in areas with low density of oncologists were less likely to receive adjuvant chemotherapy (OR, 0.85; P=.03). Increased travel burden was associated with a decreased likelihood of receiving adjuvant chemotherapy, regardless of insurance status. Patients with nonprivate insurance who resided in low-density oncologist areas were less likely to receive adjuvant chemotherapy. If these findings are validated prospectively, interventions to decrease geographic barriers may improve the timeliness and quality of colon cancer treatment. © 2015 by American Society of Clinical Oncology.

A descriptive study was conducted by sending a questionnaire regarding palliative care education to all certified gynecologic oncologists and gynecologic oncology fellows in Thailand. The contents of the survey included fellowship training experience, caring for the dying, patient preparation, attitudes and respondent characteristics. Statistics were analyzed by percentage, mean and standard deviation and chi-square. One hundred seventy completed questionnaires were returned; the response rate was 66%. Most certified gynecologic oncologists and fellows in gynecologic oncology have a positive attitude towards palliative care education, and agree that "psychological distress can result in severe physical suffering". It was found that the curriculum of gynecologic oncology fellowship training equally emphasizes three aspects, namely managing post-operative complications, managing a patient at the end of life and managing a patient with gynecologic oncology. As for experiential training during the fellowship of gynecologic oncology, education regarding breaking bad news, discussion about goals of care and procedures for symptoms control were mostly on-the-job training without explicit teaching. In addition, only 42.9% of respondents were explicitly taught the coping skill for managing their own stress when caring for palliative patients during fellowship training. Most of respondents rated their clinical competency for palliative care in the "moderately well prepared" level, and the lowest score of the competency was the issue of spiritual care. Almost all certified gynecologic oncologists and fellows in gynecologic oncology have a positive attitude towards learning and teaching in palliative care. In this

    Purpose: Recently, involved-site radiation therapy (ISRT) guidelines have been developed and published to replace the previous concept of involved-field radiation therapy for patients with lymphoma. However, these ISRT guidelines may be interpreted in different ways, posing difficulties for prospective clinical trials. This study reports survey results regarding interpretation of the ISRT guidelines. Methods and Materials: Forty-four expert lymphoma radiation oncologists were asked to participate in a survey that included 7 different cases associated with 9 questions. The questions pertained to ISRT contouring and asked respondents to choose between 2 different answers (no “correct” answer) and a third write-in option allowed. Results: Fifty-two percent of those surveyed responded to the questionnaire. Among those who responded, 72% have practiced for >10 years, 46% have treated >20 Hodgkin lymphoma cases annually, and 100% were familiar with the ISRT concept. Among the 9 questions associated with the 7 cases, 3 had concordance among the expert radiation oncologists of greater than 70%. Six of the questions had less than 70% concordance (range, 56%-67%). Conclusions: Even among expert radiation oncologists, interpretation of ISRT guidelines is variable. Further guidance for ISRT field design will be needed to reduce variability among practicing physicians.

  12. Can positron emission tomography be more than a diagnostic tool? A survey on clinical practice among radiation oncologists in India

    Full Text Available Aim: The purpose of the survey was to understand the role of positron emission tomography (PET in clinical radiotherapy practice among the radiation oncologists′ in India. Settings and Design: An online questionnaire was developed to survey the oncologists on their use of PET, viewing protocols, contouring techniques practiced, the barriers on the use of PET and the need for training in use of PET in radiotherapy. The questionnaire was sent to about 500 oncologists and 76 completed responses were received. Results: The survey shows that radiation oncologists use PET largely to assess treatment response and staging but limitedly use it for radiotherapy treatment planning. Only manual contouring and fixed threshold based delineation techniques (e.g. 40% maximum standard uptake value [SUV max ] or SUV 2.5 are used. Cost is the major barrier in the wider use of PET, followed by limited availability of FDG radionuclide tracer. Limited or no training was available for the use of PET. Conclusions: Our survey revealed the vast difference between literature suggestions and actual clinical practice on the use of PET in radiotherapy. Additional training and standardization of protocols for use of PET in radiotherapy is essential for fully utilizing the capability of PET.

    To evaluate the impact of mobile devices and apps on the daily clinical activity of young radiation oncologists. A web-based questionnaire was sent to 382 young (≤ 40 years) members of the Italian Association of Radiation Oncology (AIRO). The 14 items investigated the diffusion of mobile devices (smartphones and/or tablets), their impact on daily clinical activity, and possible differences perceived by the participants over time. A total of 158 questionnaires were available for statistical evaluation (response rate 41%). Up to 75% of respondents declared they used an electronic device during their clinical activity. Conversely, 82% considered the impact of smartphones/tables on daily practice low to moderate. Daily device use increased significantly from 2009 to 2012, with high daily use rates rising from 5% to 39.9%. Fulfillment of professional needs was declared by less than 42% of respondents and compliance with app indications by 32%. Almost all physicians desired in 2012 a comprehensive website concerning a variety of apps covering radiation oncologists' needs. Mobile devices are widely used by young Italian radiation oncologists in their daily clinical practice, while the indications so obtained are not always followed. Nevertheless, it would be important to verify the consistency of information found within apps, in order to avoid potential errors that might be detrimental to patients.

    Three violent eruptions of the Mount St. Helens volcano on 18 and 24 May and 13 June terminated the period of background aerosol prevailing in the stratosphere since the end of 1976, after the decay of the volcanic aerosols injected by the Fuego eruption in 1974. The Mt. St. Helens eruption cloud arrived over mid-Europe on 26 May. The subsequent formation of a multi-layered aerosol structure between 12 and 24 km could be observed by the ground-based lidar at Garmisch-Partenkirchen. The highest altitude of 24 km was reached on 30 June, the maximum scattering ratio of 4.8 at 21 km on 14 July. The scattering ratios observed indicate that the St. Helens eruption is comparable to that of Fuego in 1974.

    As a scientist and science educator, Helen Sawyer Hogg served astronomy, and especially variable star astronomy, in diverse ways while raising a family. Her long interest in and support of the AAVSO over many years took place in the context of not only that busy scientific and writing career, but also one of personal struggle to achieve parity as a female in a largely male profession. This biographical sketch demonstrates that her path to eventual status as “the Canadian face of astronomy” was both difficult and filled with uncertainty.

    Jane Wright was a fundamental researcher in cancer chemotherapy in the 1950s-1980s and was one of the first scientists to test anti-cancer drugs on humans rather than solely on mice, discovering the use of the popular antimetabolite drug methotrexate on solid tumours. From her research she was able to conclude which specific anti-cancer agents would have the greatest lethal effect on a patient's certain cancer type and she invented a method of delivering chemotherapy agents directly to an internal cancer site. During a time when the Civil Rights in the United States of America were undergoing a transformation to reduce the discrimination and segregation imposed on African Americans and the civil rights activist Martin Luther King Jr made a speech to call for an end to racism in 1963, Jane Wright became the first African American to hold such a high position at a nationally recognised institution and the first woman to be elected President of the New York Cancer Society. US President Lyndon B Johnson appointed Jane to the President's Commission of Heart Disease, Cancer and Stroke (serving 1964-1965) and the National Cancer Advisory Board (serving 1966-1970). Jane retired in 1987 by which time she had published more than 75 scientific papers, led delegations of oncologists in China, the former Soviet Union, Africa and Europe and held key positions in various international and national organisations. Jane Wright passed away on 19 February 2013 aged 93 but her legacy lives on in the name of an award from the American Association of Cancer Research.

    Purpose: Rapid evolution of imaging technologies and their integration into radiation therapy practice demands that radiation oncology (RO) training curricula be updated. The purpose of this study was to develop an entry-to-practice image literacy competency profile. Methods and Materials: A list of 263 potential imaging competency items were assembled from international objectives of training. Expert panel eliminated redundant or irrelevant items to create a list of 97 unique potential competency items. An international 2-round Delphi process was conducted with experts in RO. In round 1, all experts scored, on a 9-point Likert scale, the degree to which they agreed an item should be included in the competency profile. Items with a mean score ≥7 were included, those 4 to 6 were reviewed in round 2, and items scored <4 were excluded. In round 2, items were discussed and subsequently ranked for inclusion or exclusion in the competency profile. Items with >75% voting for inclusion were included in the final competency profile. Results: Forty-nine radiation oncologists were invited to participate in round 1, and 32 (65%) did so. Participants represented 24 centers in 6 countries. Of the 97 items ranked in round 1, 80 had a mean score ≥7, 1 item had a score <4, and 16 items with a mean score of 4 to 6 were reviewed and rescored in round 2. In round 2, 4 items had >75% of participants voting for inclusion and were included; the remaining 12 were excluded. The final list of 84 items formed the final competency profile. The 84 enabling competency items were aggregated into the following 4 thematic groups of key competencies: (1) imaging fundamentals (42 items); (2) clinical application (27 items); (3) clinical management (5 items); and (4) professional practice (10 items). Conclusions: We present an imaging literacy competency profile which could constitute the minimum training standards in radiation oncology residency programs.

    We sought to identify how gynecologic oncologists approach reproductive counseling for their fertile, reproductive age patients, and their experience with unplanned pregnancies. Members of the Society of Gynecologic Oncology (SGO) were surveyed electronically regarding consistency of counseling patterns of contraception and fertility concerns, most and least common contraceptive methods utilized, referral patterns, and incidence of unplanned pregnancy. Of the 1424 SGO members identified, 261 participated in the questionnaire, yielding a response rate of 18%. Eighty-two percent of respondents agreed unplanned pregnancy is a potential problem, but only 57% believed their patients understood unplanned pregnancy is possible during treatment. Half of respondents report "always" in terms of frequency that contraception is addressed among their high-risk patients. After adjustment for gender, we found that the odds of reporting providing fertility counseling were nearly three times higher among attendings as compared to fellows [AOR = 2.72; 95% CI = (1.44, 5.12), three times higher in women as compared to men [AOR = 2.80; 95% CI = (1.46, 5.38)], as well as in individuals 50 + years as compared to those unplanned pregnancies, to their knowledge, in the previous five years of clinical practice. Most providers acknowledge that unplanned pregnancy is a potential risk in fertile gynecologic oncology patients, but only half believe their patients understand an unplanned pregnancy is possible. An opportunity exists to provide more directed counseling regarding fertility during and after cancer therapy, and to educate patients and providers regarding more reliable, long acting contraceptive methods.

  2. An assessment of ground-nest depredation in a catastrophically disturbed region, Mount St. Helens, Washington

    The explosive eruption of the Mount St. Helens volcano on 18 May 1980 severely affected a large ar- ray of plant and animal populations (Edwards and Schwartz 1981, MacMahon 1982, Wissmar et al. 1982) over a vast area (>600 kM2) (Fig. 1). Volcanic eruptions are relatively common agents of large-scale biotic disturbance, yet few studies have addressed either short- or long-term effects on avian populations (see Hayward et al. 1982 for entry on pre-1980 literature). We present data gathered during 1980- 1984 on relative abundances of birds in disturbed areas near Mount St. Helens. These data indicate that a ground-nesting species was numerically dominant in the early posteruption avifauna. We also test the null hypothesis that predation rates on ground nests were unaltered by the eruption. We assumed that the breeding abundance of ground-nesting species is affected significantly by nesting success in previous years (Duebbert and Lokemoen 1980) and speculated whether dramatic changes in ground-nest predation rate might have occurred as a result of the eruption.

    The cataclysmic eruption of Mount St. Helens on May 18, 1980, resulted in a large, north-facing amphitheater, with a steep headwall rising 700 m above the crater floor. In this deeply shaded niche a glacier, here named the Amphitheater glacier, has formed. Tongues of ice-containing crevasses extend from the main ice mass around both the east and the west sides of the lava dome that occupies the center of the crater floor. Aerial photographs taken in September 1996 reveal a small glacier in the southwest portion of the amphitheater containing several crevasses and a bergschrund-like feature at its head. The extent of the glacier at this time is probably about 0.1 km2. By September 2001, the debris-laden glacier had grown to about 1 km2 in area, with a maximum thickness of about 200 m, and contained an estimated 120,000,000 m3 of ice and rock debris. Approximately one-third of the volume of the glacier is thought to be rock debris derived mainly from rock avalanches from the surrounding amphitheater walls. The newly formed Amphitheater glacier is not only the largest glacier on Mount St. Helens but its aerial extent exceeds that of all other remaining glaciers combined.

    A reference source equalization method using regional surface waves from the Mount St. Helens eruption of May 18, 1980, and the Elk Lake event of February 14, 1981, was used to determine the St. Helens eruption source time history. The time domain deconvolution signals display a complex series of pulses lasting 250 s. An initial pulse was isolated and was found to have a smoothly varying two-lobed radiation pattern for both Love and Rayleigh waves, suggesting a near-horizontal point force directed south consistent with previous results. The initial southward force corresponds to the acceleration of the landslide in a northern direction about 5-10 s after the triggering earthquake. Lateral forces were isolated 70-140 s later, consistent with the occurrence of the large lateral blast and the slide changing its direction down the Toutle River Valley. There also appears to be significant source activity between 140 and 250 s after the initial pulse. This later activity exhibits forces in the northwest-southeast azimuth and may correspond to the final deceleration of the landslide. Several vertical pulses were located between 10-60 and 100-120 s after the eruption began. Much of the vertical force represents the two sets of explosions which occurred during the eruption.

    Current data and models for Mount St. Helens volcano (Washington, United States) suggest relatively rapid transport from magma genesis to eruption, with no evidence for protracted storage or recycling of magmas. However, we show here that complex zircon age populations extending back hundreds of thousands of years from eruption age indicate that magmas regularly stall in the crust, cool and crystallize beneath the volcano, and are then rejuvenated and incorporated by hotter, young magmas on their way to the surface. Estimated dissolution times suggest that entrained zircon generally resided in rejuvenating magmas for no more than about a century. Zircon elemental compositions reflect the increasing influence of mafic input into the system through time, recording growth from hotter, less evolved magmas tens of thousands of years prior to the appearance of mafic magmas at the surface, or changes in whole-rock geochemistry and petrology, and providing a new, time-correlated record of this evolution independent of the eruption history. Zircon data thus reveal the history of the hidden, long-lived intrusive portion of the Mount St. Helens system, where melt and crystals are stored for as long as hundreds of thousands of years and interact with fresh influxes of magmas that traverse the intrusive reservoir before erupting. ?? 2010 Geological Society of America.

    Studies show that 30-50% of medical oncologists experience burnout, but little is known about burnout among surgical oncologists. We hypothesized that wide variation in burnout and career satisfaction exist among surgical oncologists. In April 2006, members of the Society of Surgical Oncology (SSO) were sent an anonymous, cross-sectional survey evaluating demographic variables, practice characteristics, career satisfaction, burnout, and quality of life (QOL). Burnout and QOL were measured using validated instruments. Of the 1519 surgical oncologists surveyed, 549 (36%) responded. More than 50% of respondents worked more than 60 hours per week while 24% performed more than 10 surgical cases per week. Among the respondents, 72% were academic surgical oncologists and 26% spent at least 25% of their time to research. Seventy-nine percent stated that they would become a surgical oncologist again given the choice. Overall, 28% of respondents had burnout. Burnout was more common among respondents age 50 years or younger (31% vs 22%; P = .029) and women (37% vs 26%; P = .031). Factors associated with a higher risk of burnout on multivariate analysis were devoting less than 25% of time to research, had lower physical QOL, and were age 50 years or younger. Burnout was associated with lower satisfaction with career choice. Although surgical oncologists indicated a high level of career satisfaction, nearly a third experienced burnout. Factors associated with burnout in this study may inform efforts by program directors and SSO members to promote personal health and retain the best surgeons in the field of surgical oncology. Additional research is needed to inform evidenced-based interventions at both the individual and organizational level to reduce burnout.

    Background Some anticipate that physician and parents will be ill-prepared or unprepared for the clinical introduction of genome sequencing, making it ethically disruptive. Procedure As part of the Baylor Advancing Sequencing in Childhood Cancer Care (BASIC3) study, we conducted semi-structured interviews with 16 pediatric oncologists and 40 parents of pediatric patients with cancer prior to the return of sequencing results. We elicited expectations and attitudes concerning the impact of sequencing on clinical decision-making, clinical utility, and treatment expectations from both groups. Using accepted methods of qualitative research to analyze interview transcripts, we completed a thematic analysis to provide inductive insights into their views of sequencing. Results Our major findings reveal that neither pediatric oncologists nor parents anticipate sequencing to be an ethically disruptive technology, because they expect to be prepared to integrate sequencing results into their existing approaches to learning and using new clinical information for care. Pediatric oncologists do not expect sequencing results to be more complex than other diagnostic information and plan simply to incorporate these data into their evidence-based approach to clinical practice although they were concerned about impact on parents. For parents, there is an urgency to protect their chil's health and in this context they expect genomic information to better prepare them to participate in decisions about their chil's care. Conclusion Our data do not support concern that introducing genome sequencing into childhood cancer care will be ethically disruptive, i.e., leave physicians or parents ill-prepared or unprepared to make responsible decisions about patient care.

    2004-08-01

    We present measurements of the whole scattering matrix as a function of the scattering angle at a wavelength of 632.8 nm in the scattering angle range 3°-174° of randomly oriented particles taken from seven samples of volcanic ashes corresponding to four different volcanic eruptions: the 18 May 1980 Mount St. Helens eruption, the 1989-1990 Redoubt eruption, and the 18 August and 17 September 1992 Mount Spurr eruptions. The samples were collected at different distances from the vent. The samples studied contain large mass fractions of fine particles and were chosen to represent ash that could remain in the atmosphere for at least hours or days. They include fine ashfall samples that fell at a variety of distances from the volcano and pyroclastic flows that retained their fine fractions. Together, they represent a range of ashes likely to remain in the atmosphere in volcanic clouds following eruptions from convergent plate boundary volcanoes, Earth's most important group of explosive sources of ash. All measured scattering matrix elements are confined to rather limited domains when plotted as functions of the scattering angle following the general trends presented by irregular mineral particles. This similarity in the scattering behavior justifies the construction of an average scattering matrix for volcanic ash particles as a function of the scattering angle. To facilitate the use of the average scattering matrix for multiple-scattering calculations with polarization included, we present a synthetic scattering matrix based on the average scattering matrix for volcanic ashes and the assumption that the diffraction forward scattering peak is the same for randomly oriented nonspherical particles and projected-surface-area-equivalent spheres. This synthetic scattering matrix is normalized so that the average of its 1-1 element over all directions equals unity. It is available in the full range from 0° to 180° and can be used, for example, for interpretation of

    Purpose Patients who develop a strong alliance with their health care providers have been shown to have higher levels of psychosocial well-being and rates of treatment adherence. Young adults with cancer have lower levels of psychosocial well-being and treatment adherence relative to patients with cancer in other age groups. This study sought to evaluate the relationships between the patient-oncologist alliance, psychosocial well-being, and treatment adherence in young adults with advanced cancer. Patients and Methods Ninety-five young adults (age 20 to 40 years) with advanced cancer were administered measures of alliance, psychosocial well-being, willingness to adhere to treatment, and treatment adherence. Relationships between alliance and psychosocial well-being were examined bivariately. Multiple linear regression models examined the relationship between alliance and adherence, controlling for confounding influences (eg, psychosocial well-being). Results Alliance was significantly (P ≤ .01) and positively associated with greater perceived social support and less severe illness-related grief. After controlling for significant confounding influences (ie, metastases, appraised support, and grief), alliance remained significantly (P ≤ .01) associated with greater willingness to adhere to treatment and greater adherence to oral medication. Conclusion By developing a strong alliance, oncologists may enhance psychosocial well-being and increase treatment adherence in young adult patients with advanced cancer. PMID:23530105

    Cancer pain continues to be undertreated in up to half of cases, despite the availability of evidence-based guidelines. This study aimed to: (i) identify barriers and facilitators to adult cancer pain assessment and management, as perceived by Australian health professionals; (ii) establish the perceived need for new Australian guidelines and implementation strategy; (iii) identify which guidelines are used; (iv) identify barriers and facilitators to guideline use. This article focuses on the perceptions of responding oncologists. A cross-sectional survey was administered online. Invitations were circulated via peak bodies and clinical leaders. Comments were coded independently by two researchers. In all 76 oncologists self-reported high concordance with evidence-based recommendations, except validated pain scales. Perceived barriers to pain management included insufficient non-pharmacological interventions, access to /coordination between services, and time. Only 22 percent of respondents reported using pain guidelines. Perceived barriers to guideline use included lack of access, awareness and any single standard. Respondents were generally supportive of new Australian guidelines and especially an implementation strategy. Barriers to evidence-based practice and guideline use identified by our survey might be addressed via a clinical pathway that gives step-by-step guidance on evidence-based practice along with a framework for evaluation. Particular attention should be paid to promoting use of validated scales, patient education and non-pharmacological interventions, training of an appropriately skilled workforce and improving care coordination. Challenges are discussed. © 2012 Wiley Publishing Asia Pty Ltd.

    Purpose: Intraoperative electron beam radiation therapy (IOERT) involves a modified strategy of conventional radiation therapy and surgery. The lack of specific planning tools limits the spread of this technique. The purpose of the present study is to describe a new simulation and planning tool and its initial evaluation by clinical users. Methods and Materials: The tool works on a preoperative computed tomography scan. A physician contours regions to be treated and protected and simulates applicator positioning, calculating isodoses and the corresponding dose-volume histograms depending on the selected electron energy. Three radiation oncologists evaluated data from 15 IOERT patients, including different tumor locations. Segmentation masks, applicator positions, and treatment parameters were compared. Results: High parameter agreement was found in the following cases: three breast and three rectal cancer, retroperitoneal sarcoma, and rectal and ovary monotopic recurrences. All radiation oncologists performed similar segmentations of tumors and high-risk areas. The average applicator position difference was 1.2 {+-} 0.95 cm. The remaining cancer sites showed higher deviations because of differences in the criteria for segmenting high-risk areas (one rectal, one pancreas) and different surgical access simulated (two rectal, one Ewing sarcoma). Conclusions: The results show that this new tool can be used to simulate IOERT cases involving different anatomic locations, and that preplanning has to be carried out with specialized surgical input.

    In the USA and most European countries, cancer diagnoses are disclosed to patients. In China, however, the trend towards full disclosure has progressed slowly. The present study aimed to explore attitudes toward truth-telling practice among physicians, patients, patients' family members, and the general population, and reasons for non-disclosure. We administered a short survey to 212 physicians, 143 patients with cancer, 413 family members of patients with cancer, and 1,415 members of the general population. A MANOVA was performed to examine group differences in attitudes toward cancer disclosure. In addition, we interviewed 20 oncologists. Interview data was analyzed using NVivo10. After the interview, we administered another short survey to 143 patients with cancer. Quantitative data indicated that physicians were the least, and patients the most, in favor of disclosure. Qualitative data among physicians and follow-up surveys among cancer patients revealed five reasons for the concealment of cancer diagnoses by physicians, including lack of awareness of patients' right to knowledge, cultural influences, insufficient medical resources and training, families' financial concerns, and the need to protect doctors from violence. There is a discrepancy between the needs of patients and those in medical practice. These results deepen our understanding regarding the reasons for oncologists' attitudes towards non-disclosure.

    Palliative care is considered an integral part of oncology and communicating this with patients is an unavoidable task for oncologists. This contribution investigated to what extent communication skills for communicating palliative care with patients are trained in the formal academic training program in medical oncology in Flanders, Belgium. The programme is based on the recommendations for a Global Core Curriculum in Medical Oncology, developed by The American Society of Clinical Oncology (ASCO) together with the European Society for Medical Oncology (ESMO). For this qualitative study, data were collected using document analysis from the ESMO/ASCO recommendations and the documents of the Flanders' medical oncology programme complemented with interviews with Flemish medical oncology trainees. Few recommendations for training communication skills to communicate about palliative care were found in the ASMO/ASCO recommendations and even less in the Flanders' programme documents. Trainees are mainly exposed to palliative care communication during the clinical practice of their training. Only very few lectures or seminars are devoted to palliative care and even less on communication about palliative care. They reported several barriers to communicate about palliative care. This study revealed promising developments for the training of Flemish medical oncologists to discuss palliative care. However, there is still a need for more theoretical training on palliative care complemented with communication skills trainings. Communication training in general needs to be fully integrated as a core skill within the medical curriculum at large and should be promoted as lifelong learning and competency development.

    Directory of Open Access Journals (Sweden)

    Ed Montano

    2013-12-01

    Full Text Available This commentary responds to some of the debates and issues raised by Alinka Greasley and Helen Prior's paper on DJing and musical shape. In particular, I focus on the use of technology by DJs, and how shifts within this domain are redefining the concept and associated skills of DJing. Technological change is having a significant impact on music production and distribution within contemporary electronic dance music culture. Tangible formats and their playback platforms are increasingly fading into the history of DJ culture, and have been replaced with computers and software. In the process, the physicality of DJing, and the values of authenticity this physicality informs, have been reframed and renegotiated in the discourse that circulates within dance music culture. I suggest that Greasley and Prior's work provides a solid foundation for further investigations into not only the specifics of DJing and shape, but also the broader technological, social and cultural contexts of DJing as a contemporary artistic practice.

    Duany, Jorge

    2010-01-01

    This article assesses Helen I. Safa's legacy to anthropological thought in Puerto Rico. The first part of the article locates Safa's research on the Island within a long tradition of fieldwork by U.S. scholars since the early twentieth century. More recent research, conducted mostly by Puerto Rican women anthropologists and other social scientists, has expanded upon Safa's insights on gender and work. The second part of the essay analyzes Safa's major empirical work, The Urban Poor of Puerto Rico: A Study in Development and Inequality. Above all, this book helped overcome the theoretical impasse over the culture of poverty that characterized much of urban anthropology during the 1960s and 1970s. The article concludes with an appraisal of the relevance of Safa's work for the ethnography of contemporary Puerto Rico.

    We present a combined 3D P-wave attenuation, 2D S-coda attenuation, and 3D S-coda scattering tomography model of fluid pathways, feeding systems, and sediments below Mount St. Helens (MSH) volcano between depths of 0 and 18 km. High-scattering and high-attenuation shallow anomalies are indicative of magma and fluid-rich zones within and below the volcanic edifice down to 6 km depth, where a high-scattering body outlines the top of a deeper aseismic velocity anomaly. Both the volcanic edifice and these structures induce a combination of strong scattering and attenuation on any seismic wave-field, particularly those recorded on the northern and eastern flanks of the volcanic cone. North of the cone, between depths of 0 and 10 km, a low-velocity, high-scattering, and high-attenuation north-south trending trough is attributed to thick piles of Tertiary marine sediments within the St. Helens Seismic Zone. A laterally-extended 3D scattering contrast at depths of 10 to 14 km is related to the boundary between upper and lower crust, and caused in our interpretation by the large scale interaction of the Siletz terrane with the Cascade arc crust. This contrast presents a low scattering, 4-6 km2 "hole" under the north-eastern flank of the volcano. We infer that this section represents the main path of magma ascent from depths greater than 6 km at MSH, with a small north-east shift in the lower plumbing system of the volcano. We conclude that combinations of different non-standard tomographic methods, and particularly the application of full-waveform tomography to highly heterogeneous media, represent the future of seismic volcano imaging.

  7. A continuous record of intereruption velocity change at Mount St. Helens from coda wave interferometry

    In September 2004, Mount St. Helens volcano erupted after nearly 18 years of quiescence. However, it is unclear from the limited geophysical observations when or if the magma chamber replenished following the 1980–1986 eruptions in the years before the 2004–2008 extrusive eruption. We use coda wave interferometry with repeating earthquakes to measure small changes in the velocity structure of Mount St. Helens volcano that might indicate magmatic intrusion. By combining observations of relative velocity changes from many closely located earthquake sources, we solve for a continuous function of velocity changes with time. We find that seasonal effects dominate the relative velocity changes. Seismicity rates and repeating earthquake occurrence also vary seasonally; therefore, velocity changes and seismicity are likely modulated by snow loading, fluid saturation, and/or changes in groundwater level. We estimate hydrologic effects impart stress changes on the order of tens of kilopascals within the upper 4 km, resulting in annual velocity variations of 0.5 to 1%. The largest nonseasonal change is a decrease in velocity at the time of the deep Mw = 6.8 Nisqually earthquake. We find no systematic velocity changes during the most likely times of intrusions, consistent with a lack of observable surface deformation. We conclude that if replenishing intrusions occurred, they did not alter seismic velocities where this technique is sensitive due to either their small size or the finite compressibility of the magma chamber. We interpret the observed velocity changes and shallow seasonal seismicity as a response to small stress changes in a shallow, pressurized system.

We infer that this section represents the main path of magma ascent from depths greater than 6 km at MSH, with a small north-east shift in the lower plumbing system of the volcano. We conclude that combinations of different nonstandard tomographic methods, leading toward full-waveform tomography, represent the future of seismic volcano imaging.

    We report the results of recent geologic mapping and radiometric dating that add considerable detail to our understanding of the eruptive history of Mount St. Helens before its latest, or Spirit Lake, stage. New data and reevaluation of earlier work indicate at least two eruptive periods during the earliest, or Ape Canyon, stage, possibly separated by a long hiatus: one about 300-250 ka and a second about 160–35 ka. Volcanism during this stage included eruption of biotite- and quartz-bearing dacite domes and pyroclastic flows in the area west of and beneath the present-day edifice, accompanied by the deposition of set C tephras. Ape Canyon-stage rocks are compositionally similar to younger Mount St. Helens dacite.

    11 years ago, the European Network for Light Ion Therapy (ENLIGHT) was established as a multidisciplinary network of engineers, physicists and clinicians with a common interest in the development of hadron therapy in Europe. ENLIGHT is coordinated from the European Centre for Nuclear Research (CERN), the home of the Large Hadron Collider. The network has evolved into a mature platform for research, with more than 100 researchers working in CERN and its allied research centres. One of the benefits of hosting this network at CERN is the ability to translate hardware and software developments, originally developed in the High Energy Physics domain, into clinical applications. From the perspective of a clinical radiation oncologist within the network, this commentary reviews the ways in which leading edge technological developments in detectors and solid state physics, Monte-Carlo simulation, grid computing and accelerator design have trickled down into real-world clinical applications.

    Purpose: To evaluate the actual work environment of radiation oncologists (ROs) in Japan in terms of working pattern, patient load, and quality of cancer care based on the relative time spent on patient care. Methods and Materials: In 2008, the Japanese Society of Therapeutic Radiology and Oncology produced a questionnaire for a national structure survey of radiation oncology in 2007. Data for full-time ROs were crosschecked with data for part-time ROs by using their identification data. Data of 954 ROs were analyzed. The relative practice index for patients was calculated as the relative value of care time per patient on the basis of Japanese Blue Book guidelines (200 patients per RO). Results: The working patterns of RO varied widely among facility categories. ROs working mainly at university hospitals treated 189.2 patients per year on average, with those working in university hospitals and their affiliated facilities treating 249.1 and those working in university hospitals only treating 144.0 patients per year on average. The corresponding data were 256.6 for cancer centers and 176.6 for other facilities. Geographically, the mean annual number of patients per RO per quarter was significantly associated with population size, varying from 143.1 to 203.4 (p < 0.0001). There were also significant differences in the average practice index for patients by ROs working mainly in university hospitals between those in main and affiliated facilities (1.07 vs 0.71: p < 0.0001). Conclusions: ROs working in university hospitals and their affiliated facilities treated more patients than the other ROs. In terms of patient care time only, the quality of cancer care in affiliated facilities might be worse than that in university hospitals. Under the current national medical system, working patterns of ROs of academic facilities in Japan appear to be problematic for fostering true specialization of radiation oncologists.

    To conduct a nationwide academic hospital patterns of the practice status and principles of radiotherapy for prostate cancer. The survey will help develop the framework of a database of Korean in Patterns of Case Study. A questionnaire about radiation treatment status and principles was sent to radiation oncologists in charge of prostate cancer treatment at thirteen academic hospitals in Korea. The data was analyzed to find treatment principles among the radiation oncologists when treating prostate cancer. The number of patients with prostate cancer and treated with radiation ranged from 60 to 150 per academic hospital in Seoul City and 10 to 15 outside of Seoul City in 2006. The primary diagnostic methods of prostate cancer included the ultrasound guided biopsy on 6 to 12 prostate sites (mean=9), followed by magnetic resonance imaging and a whole body bone scan. Internal and external immobilizations were used in 61.5% and 76.9%, respectively, with diverse radiation targets. Whole pelvis radiation therapy (dose ranging from 45.0 to 50.4 Gy) was performed in 76.9%, followed by the irradiation of seminal vesicles (54.0{approx}73.8 Gy) in 92.3%. The definitive radiotherapy doses were increased as a function of risk group, but the range of radiation doses was wide (60.0 to 78.5 Gy). Intensity modulated radiation therapy using doses greater than 70 Gy, were performed in 53.8% of academic hospitals. In addition, the simultaneous intra-factional boost (SIB) technique was used in three hospitals; however, the target volume and radiation dose were diverse. Radiation therapy to biochemical recurrence after a radical prostatectomy was performed in 84.6%; however, the radiation dose was variable and the radiation field ranged from whole pelvis to prostate bed. The results of this study suggest that a nationwide Korean Patterns of Care Study is necessary for the recommendation of radiation therapy guidelines of prostate cancer.

    Oncologists are at high risk of poor mental health. Prior research has focused on burnout, and has identified heavy workload as a key predictor. Compassion fatigue among physicians has generally received less attention, although medical specialties such as oncology may be especially at risk of compassion fatigue. We contribute to research by identifying predictors of both burnout and compassion fatigue among oncologists. In doing so, we distinguish between quantitative workload (e.g., work hours) and subjective work pressure, and test whether work-family conflict mediates the relationships between work pressure and burnout or compassion fatigue. In a cross-sectional study, oncologists from across Canada (n = 312) completed questionnaires assessing burnout, compassion fatigue, workload, time pressure at work, work-family conflict, and other personal, family, and occupational characteristics. Analyses use Ordinary Least Squares regression. Subjective time pressure at work is a key predictor of both burnout and compassion fatigue. Our results also show that work-family conflict fully mediates these relationships. Overall, the models explain more of the variation in burnout as compared to compassion fatigue. Our study highlights the need to consider oncologists' subjective time pressure, in addition to quantitative workload, in interventions to improve mental health. The findings also highlight a need to better understand additional predictors of compassion fatigue.

    The 900-instrument Mount St. Helens nodal array recorded continuous data for approximately two weeks in the summer of 2014 and provides a remarkable opportunity to interrogate the structure beneath an active arc volcano. Two separate imaging techniques are applied to constrain both the distribution of microseismicity and subsurface velocity structure. Reverse-time source imaging is applied to the 10 km3 region beneath the volcanic edifice where most of cataloged seismicity occurred during the experiment. These efforts resulted in an order of magnitude increase in earthquake detections over the normal monitoring operations of the Pacific Northwest Seismic Network. Earthquake locations resolve a narrow, ≤1 km wide, vertical lineament of seismicity that extends from the surface to 4 km depth directly beneath the summit crater, consistent with the historical event distribution of Waite and Moran[2009]. This feature is interpreted as a fracture network that acts as a conduit connecting an underlying magma chamber to the surface. Moho imaging is achieved using the near-offset (PmP phase generated by the iMUSH active source shots that occurred during the deployment. The PmP arrivals are enhanced using short-term-average over long-term-average processing and then migrated using a 3D velocity model. The observed Moho depths range from 35-40 km with a slight eastward deepening across the Mt St Helens fracture zone. Significant variations are observed in the Moho reflectivity. Large amplitude PmP energy is observed in shots originating from the north and east whereas shots from the south-west display little-to-no PmP energy. The region above the reflective Moho is approximately coincident with areas displaying reduced lower-crustal velocities in the initial iMUSH tomography models and may therefore contain fluids and/or partial melt. Additional evidence for lower crustal fluids in this region is provided by deep-long-period (DLP) events which have historically been observed

    This report provides a detailed picture of the rockslide-debris avalanche of the May 18, 1980, eruption of Mount St. Helens volcano. It provides a characterization of the deposit, a reinterpretation of the details of the first minutes of the eruption of May 18, and insight into the transport mechanism of the mass movement. Details of the rockslide event, as revealed by eyewitness photographs, are correlated with features of the deposit. The photographs show three slide blocks in the rockslide movement. Slide block I was triggered by a magnitude 5.1 earthquake at 8:32 a.m. Pacific Daylight Time (P.D.T.). An exploding cryptodome burst through slide block II to produce the 'blast surge.' Slide block III consisted of many discrete failures that were carried out in continuing pyroclastic currents generated from the exploding cryptodome. The cryptodome continued to depressurize after slide block III, producing a blast deposit that rests on top of the debris-avalanche deposit. The hummocky 2.5 cubic kilometer debris-avalanche deposit consists of block facies (pieces of the pre-eruption Mount St. Helens transported relatively intact) and matrix facies (a mixture of rocks from the old mountain and cryptodome dacite). Block facies is divided into five lithologic units. Matrix facies was derived from the explosively generated current of slide block III as well as from disaggregation and mixing of debris-avalanche blocks. The mean density of the old cone was measured to be abut 20 percent greater than the mean density of the avalanche deposit. Density in the deposit does not decrease with distance which suggests that debris-avalanche blocks were dilated at the mountain, rather than during transport. Various grain-size parameters that show that clast size converges about a mean with distance suggest mixing during transport. The debris-avalanche flow can be considered a grain flow, where particles -- either debris-avalanche blocks or the clasts within the blocks -- collided and

    Mount St. Helens is currently the most active volcano along the Cascadia arc. Though several studies investigated the magmatic system beneath Mount St. Helens following the May 18, 1980 eruption, tomographic imaging of the system has been limited to ~10 km depth due to the distribution of earthquakes in the region. This has made it difficult to estimate the volume of the shallow magma reservoir beneath the volcano, the regions of magma entry into the lower crust, and the connectivity of this magma system throughout the crust. The latter is particularly interesting as one interpretation of the Southern Washington Cascades Conductor (SWCC) suggests that the Mount St Helens and Mount Adams volcanic systems are connected in the middle crust (Hill et al., 2009). The multi-disciplinary iMUSH (imaging Magma Under St. Helens) project is designed to investigate these and other fundamental questions associated with Mount St. Helens. Here we present the first high-resolution 2D Vp and Vs models derived from travel-time data from the iMUSH 3D active-source seismic experiment. The experiment consisted of ~6000 seismograph stations which recorded 23 explosions and hundreds of local earthquakes. Directly beneath Mount St. Helens, we observe a high Vp/Vs body, inferred to be the upper/middle crustal magma reservoir, between 4 and 13 km depth. We observe a second high Vp/Vs body, likely of magmatic origin, at roughly the same depth beneath Indian Heaven Volcanic Field, which last erupted 9 ka. Southeast of Mount St. Helens is a low Vp column extending from the middle crust, ~15 km depth, to the Moho at ~40 km depth. A cluster of deep long-period events, typically associated with injection of magma, occurs at the northwestern boundary of this low Vp column. We interpret this as the middle-lower crust magma reservoir. In the lower crust, high Vp features bound the magma reservoir directly beneath Mount St. Helens and the Indian Heaven Volcanic Field. One explanation for these high Vp

    Uncertainty remains on the origin of distal mass deposition maxima observed in many recent tephra fall deposits. In this study the link between ash aggregation and the formation of distal mass deposition maxima is investigated through reanalysis of tephra fallout from the Mount St. Helens 18 May 1980 (MSH80) eruption. In addition, we collate all the data needed to model distal ash sedimentation from the MSH80 eruption cloud. Four particle size subpopulations were present in distal fallout with modes at 2.2 ??, 4.2 ??, 5.9 ??, and 8.3 ??. Settling rates of the coarsest subpopulation closely matched predicted single-particle terminal fall velocities. Sedimentation of particles particle subpopulation with modal diameter 5.9 ?? 0.2 ?? (19 ?? 3 ??m). Mammatus on the MSH80 cloud provided a mechanism to transport very fine ash particles, with predicted atmospheric lifetimes of days to weeks, from the upper troposphere to the surface in a matter of hours. In this mechanism, ash particles initiate ice hydrometeor formation high in the troposphere. Subsequently, the volcanic cloud rapidly subsides as mammatus develop from increased particle loading and cloud base sublimation. Rapid fallout occurs as the cloud passes through the melting level in a process analogous to snowflake aggregation. Aggregates sediment en masse and form the distal mass deposition maxima observed in many recent volcanic ash fall deposits. This work provides a data resource that will facilitate tephra sedimentation modeling and allow model intercomparisons. Copyright 2009 by the American Geophysical Union.

    The stratospheric aerosol layer between 15 and 25 km altitude is an important factor in the balance of the global radiation budget. The eruption of the Mount St. Helens in Washington, USA, on 18 May 1980 violated the quasi stationary situation in the stratosphere which was established after the decay of the post-Fuego aerosol during the years 1974 to 1976. At tropopause level the cloud was observed over the east coast of the US and Canada on 21 May 1980. The further transport over the Atlantic was estimated by first guess trajectory constructions. The arrival of the eruption cloud over Europe was observed by the authors employing in-situ techniques and remote sensing. The in-situ measurements of atmospheric SO2 were performed during an aircraft ascent up to 13.7 km on 26 May 1980 over southern Scandinavia. In contrast to an aircraft ascent over southern Germany on 24 May 1980 a tenfold increase in SO2 mixing ratio at tropopause level was observed. Remote sensing by ground based ruby lidar at Garmisch-Partenkirchen (47.5°N, 11°E) from 25 May to 29 May 80 indicates an aerosol peak at a height of 11 to 12 km, which was initially coupled to the tropopause, but later clearly separated from that level.

    The 2004-2008 eruption of Mount St. Helens (MSH), Washington, was preceded by a swarm of shallow volcano-tectonic earthquakes (VTs) that began on September 23, 2004. We calculated locations and fault-plane solutions (FPS) for shallow VTs recorded during a background period (January 1999 to July 2004) and during the early vent-clearing phase (September 23 to 29, 2004) of the 2004-2008 eruption. FPS show normal and strike-slip faulting during the background period and on September 23; strike-slip and reverse faulting on September 24; and a mixture of strike-slip, reverse, and normal faulting on September 25-29. The orientation of ??1 beneath MSH, as estimated from stress tensor inversions, was found to be sub-horizontal for all periods and oriented NE-SW during the background period, NW-SE on September 24, and NE-SW on September 25-29. We suggest that the ephemeral ~90?? change in ??1 orientation was due to intrusion and inflation of a NE-SW-oriented dike in the shallow crust prior to the eruption onset. ?? 2010 Elsevier B.V.

    The effects of volcanic ash suspended in the atmosphere on the incident solar radiation was monitored at the Hanford Meteorological Station (HMS) subsequent to the major eruption of Mount St. Helens on May 18, 1980. Passage of the ash plume over Hanford resulted in a very dramatic decrease of solar radiation intensity to zero. A reduction in visibility to less than 1 km was observed, as great quantities of ash fell out of the plume onto the ground. Ash loading in the atmosphere remained very high for several days following the eruption, primarily as a result of resuspension from the surface. Visibilities remained low (2 to 8 km) during this period. Estimates of atmospheric turbidity were made from the ratio of diffuse-to-direct solar radiation; these turbidities were used to estimate extinction along a horizontal path, a quantity which can be related to visibility. Comparisons of observed and estimated visibilities were very good, in spite of the rather coarse approximations used in the estimates. Atmospheric clarity and visibility improved to near pre-eruption conditions following a period of rain showers. The diffuse-to-direct ratio of solar radiation provided a useful index for estimating volcanic ash loading of the atmosphere.

    Mt St. Helens erupted explosively in 1980, and the intense heat of this event effectively sterilized the crater. The crater is filled with significant ash and volcanic debris and the crater environment has limited vegetation despite relatively abundant water, from rainfall and snowmelt. However, microorganisms thrive in the hot springs that have developed in the crater since the 1980 eruption in this otherwise biologically hostile environment. Channelized drainages exiting the crater contain numerous hot spring sources which result from thermal heating of meteoric water and gain solutes from water-rock interactions. These solutes are important inputs for the microbial communities found within the crater thermal systems. Water samples collected in August 2004 and August 2005 from thermal springs in Step Canyon allow the opportunity to assess the effects of recent magmatic activity in the crater since September 2004, on the aqueous chemistry and microbiology of thermal spring water. We have investigated the composition of microbial communities in crater hot spring ecosystems by identifying small subunit ribosomal RNA sequences amplified directly from extracted genomic DNA. Initial screening of cloned DNA (16S rRNA gene sequence) by restriction fragment length polymorphism and sequencing indicates moderate microbial diversity in this environment with representatives from the domains Bacteria and Archaea. The presentation will examine relationships between the aqueous geochemistry and the microbial communities and temporal changes in these related to the recent magmatic activity.

    The explosivity of silicic eruptions depends on the interplay between magma rheology, exsolution kinetics, and degassing. Magma degassing is governed by the competing effects of vertical transport within the conduit and the lateral flux of gas out of the conduit (Diller et al., 2006; Jaupart and Allegre, 1991). We combine a simplified treatment of these degassing processes with thermodynamic modeling to examine the conditions present at Mount St. Helens during the spine extruding eruption from 2004 to 2008. We find that two parameters are primarily responsible for controlling the eruptive style: the magma chamber temperature, and a dimensionless parameter that gauges the efficiency of lateral degassing. Together, these parameters determine whether and where magma can solidify at depth to form a dense solid plug that is gradually extruded as a volcanic spine. We show that the small (50 oC) decrease in magma chamber temperature between eruptive activity in the 1980s and that of 2004-2008, combined with a modest increase in degassing efficiency associated with lower volumetric flux, can explain the observed change in erupted material from viscous lava flows to solidified spines. More generally, we suggest that similar threshold behavior may explain observed abrupt transitions in effusive eruptive styles at other intermediate composition volcanoes. Finally, we extrapolate our results to suggest that the increase in degassing efficiency accompanying decreasing magma supply rates may have caused the transition from explosive to effusive activity in late 1980.

    Long-period (LP, 0.5-5 Hz) seismicity is a recognized signature of unrest and eruption at volcanoes worldwide. The characteristic seismicity during the sustained dome-building phase of the 2004-2008 eruption of Mount St. Helens (MSH), USA was cyclic LP "drumbeating". However, accompanying the LP drumbeating was a near-continuous, randomly occurring series of tiny LP seismic events (LP "subevents"), which may hold important additional information on the mechanism of seismogenesis at restless volcanoes. We employ template matching, phase-weighted stacking, and full-waveform inversion to image the source mechanism of one multiplet of these LP subevents at MSH in July 2005. We apply network-based template matching to 8 days of continuous velocity waveform data from 29 June to 7 July 2005. We stack waveforms for high-quality triggers at each station and component, using a combination of linear and phase-weighted stacking to produce clean stacks for use in waveform inversion. The derived source mechanism points to the volumetric oscillation (~10 m3) of a subhorizontal crack located at shallow depth (~30 m) in an area to the south of Crater Glacier in the southern portion of the breached MSH crater. A possible excitation mechanism is the sudden condensation of metastable steam from a shallow pressurized hydrothermal system as it encounters cool meteoric water in the outer parts of the edifice.

    The Canadian history of our profession is not well known and our identity is thought to suffer as a result. Helen Primrose LeVesconte (7896-1982) is one pioneer in our development whose story has not been told. Our purpose is to explore LeVesconte's life and work in order to expand knowledge of our roots and thereby strengthen our identity. Using interpretive biography methods we draw on LeVesconte's own writings, articles written about her, and archival documents to describe turning point moments in her life and to display meaningful patterns in her work. LeVesconte's work as a clinician and her role and reputation as an educator, show her to have been a strong and visionary leader. Her views on the client's role, the importance of the therapist-client relationship, prevention, community-based programs, and vocational rehabilitation are of particular interest. Because LeVesconte educated over 1,850 students while director of the occupational therapy program at the University of Toronto, her influence has been felt throughout the country. Her perspective is compared to current practice; and questions are raised as to aspects of her legacy and philosophy that might now be reconsidered.

  12. Secondary hydroeruptions in pyroclastic-flow deposits: Examples from Mount St. Helens

    1987-01-01

    Secondary hydroeruptions occur in pyroclastic-flow deposits when water or ice is trapped beneath hot pyroclastic debris and rapidly heated to steam. These eruptions display various styles of activity including fumarolic degassing, tephra fountaining, and explosive cratering. The deposits, which occupy the layer 3 stratigraphic position on the top of pyroclastic-flow units, can be distinguished from ash-cloud material by lateral thickness variation, clast composition, and other sedimentary features. The ejecta of secondary hydroeruptions comprise a subset of hydrovolcanic pyroclastic deposits. A small secondary hydroeruption observed on the Mount St. Helens pumice plain in 1981 produced tephra that was emplaced ballistically, by deposition from base surges, and by fallout from an eruption column. Stratigraphic descriptions and grain-size analysis of the ejecta from several secondary craters on the pumice plain demonstrate that the bedforms produced by a hydroeruption change with crater diameter. In particular, craters of small diameter are surrounded by interbedded ripple-laminated ash horizons and nonstratified, fines-depleted units; large craters have ejecta ramparts comprised of coarse dunes and antidunes. These bedform changes are related to a progressive increase in eruptive energy, which produces base surges of greater power and eruptive columns of greater height. We suggest that the style of activity displayed during a secondary hydroeruption is controlled by both the total thermal energy of the system and the permeability of the pyroclastic overburden. ?? 1987.

    Nineteen stratospheric samples from the eruption plumes of Mount St. Helens were collected in five flight experiments. The plume samples were collected at various altitudes from 13.1 to 20.7 km by using the Ames cryogenic sampling system on board the NASA U-2 aircraft. The enriched, cryogenically collected samples were analyzed by chromatography. The concentrations of aerosols precursor gases (OCS, SO2, and CS2), CH3Cl, N2O, CF2Cl2, and CFCl3 were measured by gas chromatography. Large enhancement of the mixing ratio of SO2 and moderate enhancement of CS2 and OCS were found in the plume samples compared with similar measurement under pre-volcanic conditions. A fast decay rate of the SO2 mixing ratio in the plume was observed. Measurement of Cl(-), SO2(2-), and NO3(-) by ion chromatography was also carried out on water solutions prepared from the plume samples. The results obtained with this technique imply large mixing ratios of HCl, (NO + NO2 + HNO3), and SO2, in which these constituents are the respective sources of the anions. Measurement of the Rn222 concentration in the plume was made. Other stratospheric constituents in the plume samples, such as H2O, CO2, CH4, and CO, were also observed.

    We investigated upper crustal structure with data from a dense seismic array deployed around Mount St. Helens for 2 weeks in the summer of 2014. Interstation cross correlations of ambient seismic noise data from the array were obtained, and clear fundamental mode Rayleigh waves were observed between 2.5 and 5 s periods. In addition, higher-mode signals were observed around 2 s period. Frequency-time analysis was applied to measure fundamental mode Rayleigh wave phase velocities, which were used to invert for 2-D phase velocity maps. An azimuth-dependent traveltime correction was implemented to mitigate potential biases introduced due to an inhomogeneous noise source distribution. Reliable phase velocity maps were only obtained between 3 and 4 s periods due to limitations imposed by the array aperture and higher-mode contamination. The phase velocity tomography results, which are sensitive to structure shallower than 6 km depth, reveal an 10-15% low-velocity anomaly centered beneath the volcanic edifice and peripheral high-velocity anomalies that likely correspond to cooled igneous intrusions. We suggest that the low-velocity anomaly reflects the high-porosity mixture of lava and ash deposits near the surface of the edifice, a highly fractured magmatic conduit and hydrothermal system beneath the volcano, and possibly a small contribution from silicate melt.

    2011-05-01

    Full Text Available An ice nucleation parameterization accounting for the deliquescent heterogeneous freezing (DHF mode was implemented into the Weather Research Forecast (WRF model. The DHF mode refers to the freezing process for internally mixed aerosols with soluble and insoluble species that can serve as both cloud condensation nuclei (CCN and ice nuclei (IN, such as dust. A modified version of WRF was used to examine the effect of Saharan dust on the early development of Hurricane Helene (2006 via acting as CCN and IN. The WRF simulations showed the tendency of DHF mode to promote ice formation at lower altitudes in strong updraft cores, increase the local latent heat release, and produce more low clouds and less high clouds. The inclusion of dust acting as CCN and IN through the DHF mode modified the storm intensity, track, hydrometeor distribution, cloud top temperature (hence the storm radiative energy budget, and precipitation and latent heat distribution. However, changes in storm intensity, latent heating rate, and total precipitation exhibit nonlinear dependence on the dust concentration. Improvement in the representation of atmospheric aerosols and cloud microphysics has the potential to contribute to better prediction of tropical cyclone development.

    Full Text Available Ants were surveyed in three habitats at Mount St. Helens in 2008. The area most impacted by the 1980 eruption is the Pumice Plain. Less impacted is the Blowdown Zone where trees were toppled due to the blast. Two habitats were surveyed in the Pumice Plain varying in vegetation density (Pumice Plain Low-Vegetation (PPLV and Pumice Plain High-Vegetation (PPHV, and one habitat was surveyed in the Blowdown Zone (BDZ. Ten ant species were collected with the most species collected from the BDZ habitat and the least from the PPLV habitat. Ant abundance was higher at the BDZ and PPHV habitats than at the PPLV habitat. Ant biodiversity was highest at the BDZ habitat than at the PPHV and PPLV habitats. Significant correlations between ant community parameters and plant community parameters were also found. Few plants in the PPLV habitat may contribute to the lack of ants. High ant species richness at the BDZ habitat may be due to complex plant architecture. Results from this study suggest that ants are important focal species in tracking biotic recovery following disturbances.

    Stream-channel cross-section survey data are a fundamental component to studies of fluvial geomorphology. Such data provide important parameters required by many open-channel flow models, sediment-transport equations, sediment-budget computations, and flood-hazard assessments. At Mount St. Helens, Washington, the long-term response of channels to the May 18, 1980, eruption, which dramatically altered the hydrogeomorphic regime of several drainages, is documented by an exceptional time series of repeat stream-channel cross-section surveys. More than 300 cross sections, most established shortly following the eruption, represent more than 100 kilometers of surveyed topography. Although selected cross sections have been published previously in print form, we present a comprehensive digital database that includes geospatial and tabular data. Furthermore, survey data are referenced to a common geographic projection and to common datums. Database design, maintenance, and data dissemination are accomplished through a geographic information system (GIS) platform, which integrates survey data acquired with theodolite, total station, and global navigation satellite system (GNSS) instrumentation. Users can interactively perform advanced queries and geospatial time-series analysis. An accuracy assessment provides users the ability to quantify uncertainty within these data. At the time of publication, this project is ongoing. Regular database updates are expected; users are advised to confirm they are using the latest version.

    The August 2015 GeoGirls program was a project designed to inspire girls to gain an appreciation and enthusiasm for Earth sciences using Mount St. Helens as an outdoor volcanic laboratory. Occupations in the field of science and engineering tend to be held by more males than females. One way to address this is to introduce girls to possible opportunities within the geosciences and encourage them to learn more about the dynamic environment in which they live. In 2015, the GeoGirls program sought to accomplish this goal through organizing a five day-long field camp for twenty middle school-aged girls, along with four high school-aged mentors and two local teachers. This group explored Mount St. Helens guided by female scientists from the USGS Cascade Volcano Observatory (CVO), the Mount St. Helens Institute (MSHI), UNAVCO, Boise State, Georgia Tech, University of Washington and Oregon State University. To introduce participants to techniques used by volcanologists, the girls participated in hands-on experiments and research projects focusing on seismology, GPS, terrestrial lidar, photogrammetry, water and tephra. Participants also learned to collect samples, analyze data and use microscopes. Through this experience, participants acquired strategies for conducting research by developing hypotheses, making observations, thinking critically and sharing their findings with others. The success of the GeoGirls program was evaluated by participant and parent survey questionnaires, which allowed assessment of overall enthusiasm and interest in pursuing careers in the geosciences. The program was free to participants and was run jointly by MSHI and CVO and funded by NSF, the American Association of University Women, the Association for Women Geoscientists, the Association of Environmental & Engineering Geologists and private donors. The program will run again in the summer of 2016.

  20. Volcanic hazards: extent and severity of potential tephra hazard interpreted from layer Yn from Mount St. Helens, Washington (Abstract)

    Volcanoes in the conterminous United States erupt infrequently but represent a significant potential hazard. Tephra eruptions can affect broader areas and reach population centers at greater distances from a volcano than any other kind of volcanic event. Lava flows, pyroclastic flows, mudflows, and floods can be more hazardous, but they seldom extend beyond a volcano except along valleys. Severity of risk from tephra depends in part on rate of fall and grain size, but mainly on thickness. Rates of fall from future eruptions in the Cascade Range must be estimated from historic eruptions elsewhere; potential grain sizes and thicknesses can be judged from past tephra eruptions of the Cascade volcanoes themselves. Pumice layer Yn, erupted by Mount St. Helens about BC 2000, exemplifies an extensive and thick tephra resulting from a single eruptive pulse of a Cascade volcano; in thickness and volume it resembles tephra of the type Plinian eruption of Vesuvius in Italy in 79 AD. Layer Yn trends NNE from Mount St. Helens in a long narrow lobe that is much thicker at any given distance than if the layer had formed a wide lobe. On broad ridges where it should be nearly unaffected by thickening or erosion, its present (compacted) thickness is as much as 70 cm at about 50 km from the volcano, 20 cm at 100 km, and 5 cm at about 280 km. Future eruptions like that of layer Yn could produce similar thicknesses in any easterly direction between about NNE and SSE downwind from Mount St. Helens or any other explosive Cascade volcano. Weaker winds toward the west indicate that potential thicknesses are less in westerly directions.

    In an era of reduced peer-reviewed grant funding, performing academic bone oncology-related research has become increasingly challenging. Over the last 10 years we have held an annual meeting to bring together clinicians, clinician/scientists and basic biomedical researchers interested in the effects of cancer and its treatment on skeletal tissues. In the past these "Bone and the Oncologist New Updates Conference (BONUS)" meetings have served as critical catalyst for initiating productive research collaborations between attendees. The 2015 BONUS meeting format focused on potential key research themes that could form the basis of a coordinated national research strategy to tackle unmet clinical and research needs related to complications associated with cancer metastasis to bone. The three themes planned for discussion were: Is bone metastases-related pain the main issue facing patients? Are there new therapeutic targets for patients with bone metastases? How do we more firmly link basic science with clinical practice? We present a summary of lectures and commentaries from the attendees to serve as an example that other similarly motivated groups can model and share their experiences. It is our hope that these presentations will result in comments, feedback and suggestions from all those researchers interested in this important area.

    Symptom and Quality of Life (QOL) data are important patient reported outcomes. Early identification of these is critical for appropriate interventions. Data collection may be helped by modern information technology. This study examined symptoms and QOL in people with solid tumors at their first visit to a medical oncologist. We also evaluated the clinical utility of tablet computers (TC) to collect this data. This was a prospective study of 105 consecutive patients in the cancer outpatient clinic of a tertiary level academic medical center. Symptom and QOL data was collected by TC with wireless database upload. One-third participants had moderate to severe pain; almost half clinically significant pain that interfered with daily activities. Tiredness, anxiety, and drowsiness were common (prevalence - 79%, 63% and 50% respectively). One-third of those who had items identified from the Edmonton System Assessment System also volunteered other symptoms, mostly gastrointestinal problems. Many of those affected also reported impaired Global Wellbeing and low Overall QOL. There was a 98% completion rate, which took on average ten minutes. Direct observation and informal feedback from patients and physicians regarding the acceptability of TC in this setting was uniformly positive. Amongst people with newly diagnosed solid tumors clinically important psychological and physical symptoms, QOL problems and difficulties with daily activities were commonly present in the 24-hour period and in the week before a first Medical Oncology visit. Symptom and QOL data collection by TC in busy outpatient clinics showed good clinical utility.

    The past decades have seen advances in cancer treatments in terms of toxicity and side effects but progress in the treatment of advanced cancer has been modest. New drugs have emerged improving progression free survival but with little impact on overall survival, raising questions about the criteria on which to base decisions to grant marketing authorizations and about the authorization procedure itself. For decisions to be fair, transparent and accountable, it is necessary to consider the views of those with relevant expertise and experience. We conducted a Q-study to explore the views of a range of stakeholders in France, involving: 54 patients (18 months after diagnosis); 50 members of the general population; 27 oncologists; 19 healthcare decision makers; and 2 individuals from the pharmaceutical industry. Three viewpoints emerged, focussing on different dimensions entitled: 1) 'Quality of life (QoL), opportunity cost and participative democracy'; 2)'QoL and patient-centeredness'; and 3) 'Length of life'. Respondents from all groups were associated with each viewpoint, except for healthcare decision makers, who were only associated with the first one. Our results highlight plurality in the views of stakeholders, emphasize the need for transparency in decision making processes, and illustrate the importance of a re-evaluation of treatments for all 3 viewpoints. In the context of advanced cancer, our results suggest that QoL should be more prominent amongst authorization criteria, as it is a concern for 2 of the 3 viewpoints.

    To the Editors: We have read with interest and some concern the recently published editorial, "We've Got a Treatment, but What's the Disease," by Rosenthal and Glatstein. This editorial enunciates these common anxieties (? "mid-life") about radiosurgery: A) that thedure as currently practiced worldwide, even in the United States, does not in all cases rely on the talents of radiation oncologists; B) that the technique disregards fundamental (? proven) principles about radiobiology, and C) that the authors of the editorial have chosen to ignore a tremendous body of historical and clinical literature relative to outcomes. In fact, long-term clinical data have been published in a wide variety of reports during the last ten years. Their reference list does not include a single article published beyond 1992. Now let's address the first issue. While it is true that the advantages obtained by closed skull focused stereotactic single session irradiation of a small but well-defined intracranial target volume (radiosurgery) were first espoused and practiced by neuosurgeons, the goal was not to impact upon the turf of the radiation oncologist. The goal was to provide a minimally invasive treatment for many problems deep within the brain for which traditional neurosurgical procedures were neither satisfactory nor effective. The tools that allowed neurosurgeons to accomplish this goal included focused particle beams or photon beams generated by the gamma knife or by linear accelerators. The technique also required highly precise (tecnologies became available in North America. AUTHORS' RESPONSE: In response to the Letter to the Editor by Lunsford, Flickinger and Larson, our main objectives in writing that article were twofold. The first was to review those principles of fractionation derived from a near century's experience in clinical radiobioloy. We have learned over and over again that, in general, hypofractionation leads to poorer tumor control, and more frequent and severe

  6. Emerging aspects of oesophageal and gastro-oesophageal junction cancer histopathology – an update for the surgical oncologist

    Full Text Available Abstract Adenocarcinoma of the oesophagus and gastro-oesophageal junction are rapidly increasing in incidence and have a well described sequence of carcinogenesis: the Barrett's metaplasia-dysplasia-adenocarcinoma sequence. During recent years there have been changes in the knowledge surrounding disease progression, cancer management and histopathology specimen reporting. Tumours around the gastro-oesophageal junction (GOJ pose several specific challenges. Numerous difficulties arise when the existing TNM staging systems for gastric and oesophageal cancers are applied to GOJ tumours. The issues facing the current TNM staging and GOJ tumour classification systems are reviewed in this article. Recent evidence regarding the importance of several histopathologically derived prognostic factors, such as circumferential resection margin status and lymph node metastases, have implications for specimen reporting. With the rising use of multimodal treatments for oesophageal cancer it is important that the response of the tumour to this therapy is carefully documented pathologically. In addition, several controversial and novel areas such as endoscopic mucosal resection, lymph node micrometastases and the sentinel node concept are being studied. We aim to review these aspects, with special relevance to oesophageal and gastro-oesophageal cancer specimen reporting, to update the surgical oncologist with an interest in upper gastrointestinal cancer.

    Communication about palliative treatment options requires a balance between providing patients with sufficient information and not providing unwanted information. Surveys have indicated that many patients with advanced cancer express a wish to receive detailed information. In this prospective multicenter study, the information desire of patients with advanced breast or colorectal cancer was further investigated by offering treatment-related information to patients using a decision aid (DA). In addition, this study explored oncologists' awareness of their patients' information desire. Seventy-seven patients with advanced breast or colorectal cancer facing the decision whether to start second-line palliative chemotherapy were offered a DA by a nurse. This DA contained information on adverse events, tumor response, and survival. The nurse asked the patient whether each information item was desired. Ninety-five percent of patients chose to receive information on adverse events, 91 % chose to receive information on tumor response, and 74 % chose to receive information on survival. Oncologists' judgment of patients' information desire was 100, 97, and 81 %, respectively. For all three information items together, oncologists correctly judged the information desire of 62 % of patients. This study confirms that many patients with advanced cancer wish to receive detailed information on the benefits and risks of palliative treatment options when the information is actually available. Oncologists were adequately aware of this high information desire, but had some difficulty judging the information desire of individual patients. A stepped approach to giving information ("preview, ask, tell, ask") may help to better meet patients' information needs.

    The aims of this study are to assess patients' preferred and perceived decision-making roles and preference matching in a sample of German breast and colon cancer patients and to investigate how a shared decision-making (SDM) intervention for oncologists influences patients' preferred and perceived decision-making roles and the attainment of preference matches. This study is a post hoc analysis of a randomised controlled trial (RCT) on the effects of an SDM intervention. The SDM intervention was a 12-h SDM training program for physicians in combination with decision board use. For this study, we analysed a subgroup of 107 breast and colon cancer patients faced with serious treatment decisions who provided data on specific questionnaires with regard to their preferred and perceived decision-making roles (passive, SDM or active). Patients filled in questionnaires immediately following a decision-relevant consultation (t1) with their oncologist. Eleven of these patients' 27 treating oncologists had received the SDM intervention within the RCT. A majority of cancer patients (60%) preferred SDM. A match between preferred and perceived decision-making roles was reached for 72% of patients. The patients treated by SDM-trained physicians perceived greater autonomy in their decision making (p < 0.05) with more patients perceiving SDM or an active role, but their preference matching was not influenced. A SDM intervention for oncologists boosted patient autonomy but did not improve preference matching. This highlights the already well-known reluctance of physicians to engage in explicit role clarification.

    To check the interobserver agreement between radiation oncologists and therapists (RTT) using an on- and off-line cone-beam computer tomography (CBCT) protocol for setup verification in the radiotherapy of prostate cancer. The CBCT data from six prostate cancer patients treated with hypofractionated intensity-modulated radiotherapy (IMRT) were independently reviewed off-line by four observers (one radiation oncologist, one junior and two senior RTTs) and benchmarked with on-line CBCT positioning performed by a radiation oncologist immediately prior to treatment. CBCT positioning was based on manual soft-tissue registration. Agreement between observers was evaluated using weighted Cohen's kappa statistics. In total, 152 CBCT-based prostate positioning procedures were reviewed by each observer. The mean (± standard deviation) of the differences between off- and on-line CBCT-simCT registration translations along the three directions (antero-posterior, latero-lateral and cranio-caudal) and rotation around the antero-posterior axis were - 0.7 (3.6) mm, 1.9 (2.7) mm, 0.9 (3.6) mm and - 1.8 (5.0) degrees, respectively. Satisfactory interobserver agreement was found, being substantial (weighted kappa > 0.6) in 10 of 16 comparisons and moderate (0.41-0.60) in the remaining six comparisons. CBCT interpretation performed by RTTs is comparable to that of radiation oncologists. Our study might be helpful in the quality assurance of radiotherapy and the optimization of competencies. Further investigation should include larger sample sizes, a greater number of observers and validated methodology in order to assess interobserver variability and its impact on high-precision prostate cancer IGRT. In the future, it should enable the wider implementation of complex and evolving radiotherapy technologies. (orig.)

    This study aimed to evaluate the self-reported prevalence of burnout and psychological morbidity among radiation oncologists members of the Kyoto Radiation Oncology Study Group (KROSG) and to identify factors contributing to burnout. We mailed an anonymous survey to 125 radiation oncologists members of the KROSG. The survey included; the demographic data, the Maslach Burnout Inventory - Human Services Survey (MBI-HSS) and the 12-item General Health Questionnaire (GHQ-12). There were 87 responses out of 125 eligible respondents (69.6% response rate). In terms of burnout, three participants (3.4%) fulfilled the MBI-HSS criteria of having simultaneously high emotional exhaustion (EE), high depersonalization (DP) and low sense of personal accomplishment (PA). Eighteen (20.6%) reported a high score for either EE or DP meeting the alternative criteria for burnout with three of these simultaneously having high EE and high DP. The prevalence of psychological morbidity estimated using GHQ-12 was 32%. A high level of EE and low level of PA significantly correlated with high level of psychological morbidity with P burnout. This is the first study investigating the prevalence of burnout and psychological morbidity among radiation oncologists in Japan. Compared with other studies involving radiation oncologists, the prevalence of low personal accomplishment was particularly high in the present study. The prevalence of psychological morbidity was almost the double that of the Japanese general population and was significantly associated with low PA and high EE. © The Author 2016.

    The performance of sacrificial and plasma mirrors has been investigated on the HELEN laser chirped pulse amplification [CPA] beam line. Sacrificial mirrors are initially highly reflective surfaces that degrade during the course of a pulsed laser experiment. They are being considered for protecting the off axis parabolic surfaces used to focus CPA lasers from plasma physics target generated debris and shrapnel. Plasma mirrors are initially low reflectivity surfaces that transmit low intensity beams but produce a reflecting plasma surface during the course of the laser pulse. They are being investigated to prevent prepulse effects in plasma physics experiments and increase the contrast ratio of the incident laser beam.The sacrificial mirrors were operated at 45 degrees angle of incidence and an average input beam diameter of ~14 mm with intensities in the range 8 TW/cm2 to 44 TW/cm2. Dielectric protected silver and gold coatings as well as dielectric multi layers were studied as the mirror surfaces for directing all of the short pulse [500fs] laser beams onto tantalum foil targets of 10 microns thickness. Proton emissions from the foils monitored by radiochromic film were used to evaluate the beam irradiance achieved from the mirror surfaces. Glass witness plates were used to evaluate debris and shrapnel emissions from the mirror surfaces, the diagnostics and the target foils. The plasma mirrors were operated in a similar configuration but with beam diameters of ~8mm and irradiances of 57 TW/cm2 to 235 TW/cm2. Uncoated and sol gel anti-reflection coated fused silica were used as the high intensity mirror surfaces. The influence of surface coating on laser damage morphology will be described as well as post shot inspection of debris distributions.

    The 2004–2008 dome-building eruption at Mount St. Helens ended during winter 2007–2008 at a time when field observations were hampered by persistent bad weather. As a result, recognizing the end of the eruption was challenging—but important for scientists trying to understand how and why long-lived eruptions end and for public officials and land managers responsible for hazards mitigation and access restrictions. In hindsight, the end of the eruption was presaged by a slight increase in seismicity in December 2007 that culminated on January 12–13, 2008, with a burst of more than 500 events, most of which occurred in association with several tremor-like signals and a spasmodic burst of long-period earthquakes. At about the same time, a series of regular, localized, small-amplitude tilt events—thousands of which had been recorded during earlier phases of the eruption—came to an end. Thereafter, seismicity declined to 10–20 events per day until January 27–28, when a spasmodic burst of about 50 volcano-tectonic earthquakes occurred over a span of 3 h. This was followed by a brief return of repetitive “drumbeat” earthquakes that characterized much of the eruption. By January 31, however, seismicity had declined to 1–2 earthquakes per day, a rate similar to pre-eruption levels. We attribute the tilt and seismic observations to convulsive stagnation of a semisolid magma plug in the upper part of the conduit. The upward movement of the plug ceased when the excess driving pressure, which had gradually decreased throughout the eruption as a result of reservoir deflation and increasing overburden from the growing dome, was overcome by increasing friction as a result of cooling and crystallization of the plug.

    Patient-oncologist alliance and psychosocial well-being have strong associations with adherence to cancer management. For patients with cancer of unknown primary (CUP), adherence is crucial to treatment or occult primary screening plans. There has been no study investigating the relationship between alliance, psychosocial factors, and adherence in such patients or in Chinese sociocultural settings. The measures of alliance, psychosocial well-being, and adherence willingness were administered to patients with CUP, with a mean age of 58.33 ± 11.24 years. Multiple linear regression models were applied to investigate the independent relationship between alliance and adherence by controlling for socioeconomic and psychosocial confounders. Alliance was found to be independently and positively associated with greater adherence willingness and adherence to treatment and follow-up screening after controlling for significant confounders, including medical conditions, psychosocial well-being variables, and socioeconomic factors. Stronger patient-oncologist alliance may foster enhanced adherence to treatment and follow-up screening in patients with CUP. Patient-oncologist alliance seems affected by socioeconomic factors and psychosocial well-being in the Chinese sociocultural settings. Copyright © 2016 John Wiley & Sons, Ltd.

    The number of cancer patients in Europe is rising and significant advances in basic and applied cancer research are making the provision of optimal care more challenging. The concept of cancer as a systemic, highly heterogeneous and complex disease has increased the awareness that quality cancer care should be provided by a multidisciplinary team (MDT) of highly qualified healthcare professionals. Cancer patients also have the right to benefit from medical progress by receiving optimal treatment from adequately trained and highly skilled medical professionals. Built on the highest standards of professional training and continuing medical education, medical oncology is recognised as an independent medical specialty in many European countries. Medical oncology is a core member of the MDT and offers cancer patients a comprehensive and systemic approach to treatment and care, while ensuring evidence-based, safe and cost-effective use of cancer drugs and preserving the quality of life of cancer patients through the entire 'cancer journey'. Medical oncologists are also engaged in clinical and translational research to promote innovation and new therapies and they contribute to cancer diagnosis, prevention and research, making a difference for patients in a dynamic, stimulating professional environment. Medical oncologists play an important role in shaping the future of healthcare through innovation and are also actively involved at the political level to ensure a maximum contribution of the profession to Society and to tackle future challenges. This position paper summarises the multifarious and vital contributions of medical oncology and medical oncologists to today's and tomorrow's professional cancer care.

    The reawakening of Mount St. Helens after 17 years and 11 months of slumber was heralded by a swarm of shallow (depth Md >2 earthquakes were occurring at a rate of ~1 per minute. A gradual transition from volcano-tectonic to hybrid and low-frequency events occurred along with this intensification, a characteristic of many precursory swarms at Mount St. Helens before dome-building eruptions in the 1980s. The first explosion occurred October 1, 2004, 8.5 days after the first earthquakes, and was followed by three other explosions over the next four days. Seismicity declined after each explosion and after two energetic noneruptive tremor episodes on October 2 and 3. Following the last explosion of this series, on October 5, seismicity declined significantly. Over the next ten days seismicity was dominated by several event families; by October 16, spacing between events had become so regular that we dubbed the earthquakes “drumbeats.” Through the end of 2005 seismicity was dominated by these drumbeats, although occasional larger earthquakes (Md

  16. Helen Kim as New Woman and Collaborator: A Comprehensive Assessment of Korean Collaboration under Japanese Colonial Rule

    2017-02-01

    Full Text Available Although almost seventy years has passed since Korea's liberation from Japanese rule, the issue of collaboration still haunts Korea today. Attempts to resolve this issue have tended to focus attention on the traitorous actions of "collaborators" without considering the gray areas that surround their actions such as the circumstances that influenced the accused to commit their alleged traitorous acts and the intentions that drove their decisions. Helen Kim, as a "new woman" and an educator, valued the necessity of providing education for women. Yet, her efforts to realize this goal, to the contrary, forced her into actions that would later be used to construct a reputation as a Japanese collaborator. Korea's nationalist historiography has a tendency to polarize this issue by categorizing a "collaborator" as either a traitor or a patriot. However, when we take a closer look at these collaborators' lives, we discover that most collaboration happened in gray areas where it is often difficult to clearly draw a line between treason and collaboration. Helen Kim's case suggests that the issue of collaboration cannot be fully explained by nationalist historiography's framework and we must give attention to these gray areas. Through her story I hope to complicate the issue of collaboration by raising questions that address the gray areas that surround the actions of "collaborators." In doing so, I hope to challenge the nationalist historiography's propensity to oversimplify this issue and present a more nuanced understanding of it.

  17. Polyphony and counterpoint: Mechanisms of seduction in the diaries of Helen Hessel and Henri Pierre Roché

    2015-06-01

    Full Text Available Henri Pierre Roché (1879–1959, the author of Jules et Jim, has been called a general introducer, an exemplary amateur, a collector of women and art and one of the most prolific diarists and active lovers in recorded history. Author of a collection of vignettes about Don Juan, Roché was fascinated with the figure of the seducer and in his twenties planned to devote his life to the creation of a body of work which would examine moral, intellectual, social and sexual relations between women and men. To this end, he would transform his life into a laboratory where real-life experiences would become the main source of reference. Roché’s diary spans sixty years and abounds in tales of seduction. However, the most intense and captivating intrigue of seduction and betrayal in his diary, is his relationship with Helen Hessel. At the start of their affair, Roché suggested that she too should keep a diary of the maelstrom of passion into which they were plunged. Written in French, German and English, Helen Hessel’s diary captures the drama of seduction and functions on several levels: realistic, visionary, absorbed in her thoughts and emotions and yet critical of herself and others. A juxtaposed reading of the two diaries generates a fascinatingly dense texture, revealing the mechanisms of seduction at play. The counterpoint created by these two interdependent voices becomes ever more complex as one becomes aware of the intertextual references that contribute to the emerging polyphony of recorded life and love.Polifonie en kontrapunt: Meganismes van verleiding in die dagboeke van Helen Hessel en Henri Pierre Roché.

    Purpose: The American Society for Radiation Oncology (ASTRO) conducted the 2012 Radiation Oncology Workforce Survey to obtain an up-to-date picture of the workforce, assess its needs and concerns, and identify quality and safety improvement opportunities. The results pertaining to radiation oncologists (ROs) and residents (RORs) are presented here. Methods: The ASTRO Workforce Subcommittee, in collaboration with allied radiation oncology professional societies, conducted a survey study in early 2012. An online survey questionnaire was sent to all segments of the radiation oncology workforce. Respondents who were actively working were included in the analysis. This manuscript describes the data for ROs and RORs. Results: A total of 3618 ROs and 568 RORs were surveyed. The response rate for both groups was 29%, with 1047 RO and 165 ROR responses. Among ROs, the 2 most common racial groups were white (80%) and Asian (15%), and the male-to-female ratio was 2.85 (74% male). The median age of ROs was 51. ROs averaged 253.4 new patient consults in a year and 22.9 on-treatment patients. More than 86% of ROs reported being satisfied or very satisfied overall with their career. Close to half of ROs reported having burnout feelings. There was a trend toward more frequent burnout feelings with increasing numbers of new patient consults. ROs' top concerns were related to documentation, reimbursement, and patients' health insurance coverage. Ninety-five percent of ROs felt confident when implementing new technology. Fifty-one percent of ROs thought that the supply of ROs was balanced with demand, and 33% perceived an oversupply. Conclusions: This study provides a current snapshot of the 2012 radiation oncology physician workforce. There was a predominance of whites and men. Job satisfaction level was high. However a substantial fraction of ROs reported burnout feelings. Perceptions about supply and demand balance were mixed. ROs top concerns reflect areas of attention

    Relatively little attention has been devoted to the role of communication between physicians as a mechanism for individual and organisational learning about diagnostic delays. This study's objective was to elicit physicians' perceptions about and experiences with communication among physicians regarding diagnostic delays in cancer. Qualitative analysis based on seven focus groups. Fifty-one physicians affiliated with three New York-based academic medical centres participated, with six to nine subjects per group. We used content analysis to identify commonalities among primary care physicians and specialists (ie, medical and surgical oncologists). Perceptions and experiences with physician-to-physician communication about delays in cancer diagnosis. Our analysis identified five major themes: openness to communication, benefits of communication, fears about giving and receiving feedback, infrastructure barriers to communication and overcoming barriers to communication. Subjects valued communication about cancer diagnostic delays, but they had many concerns and fears about providing and receiving feedback in practice. Subjects expressed reluctance to communicate if there was insufficient information to attribute responsibility, if it would have no direct benefit or if it would jeopardise their existing relationships. They supported sensitive approaches to conveying information, as they feared eliciting or being subject to feelings of incompetence or shame. Subjects also cited organisational barriers. They offered suggestions that might facilitate communication about delays. Addressing the barriers to communication among physicians about diagnostic delays is needed to promote a culture of learning across specialties and institutions. Supporting open and honest discussions about diagnostic delays may help build safer health systems. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Hadrontherapy has been in constant progress in the past decades. Due to the increasing interest in this field and the spreading of the technique in Italy and worldwide, the Italian Society of Radiation Oncology surveyed (by an online survey) its members regarding their perception of hadrontherapy. The survey outline addressed different items all related to hadrontherapy, such as: demographics (3 items), personal knowledge (5 items), actual use in clinical practice (5 items), and future perspectives and development (5 items). The survey was filled in by 224 radiation oncologists (RO). Among them, 74.6 % were RO with more than 5 years of clinical practice, and only 10.4 % RO in training. Median age was 46 years (range 27-77). 32.24 % admitted average knowledge about heavy particles radiobiology rationale and 32.42 % about the ongoing particle therapy clinical trials. Radioresistant tumors are perceived as-principal indications for carbon ions in 39.3 % of responders, and pediatric malignancies for protons in 37 %. Re-irradiation is highly recommended for 52.2 %. Strikingly, 38.8 % of participating ROs reported that, in the daily clinical practice, approximately less than 1 out of 10 patients asks to be referred for hadrontherapy. On the other side, 35.7 % claimed need for at least 3 up to 5 particle therapy centers in Italy. Overall, the results of the present survey highlight the interest of the Italian RO community for particle therapy among the other radiotherapy technique. Analysis of our results might picture the clinical attitude of the RO community towards hadrontherapy in Italy, and help in promoting targeted initiatives to spread clinical results and knowledge about technical innovations in this field.

    Background The management of small-cell lung cancer (sclc) with radiotherapy (rt) varies, with many treatment regimens having been described in the literature. We created a survey to assess patterns of practice and clinical decision-making in the management of sclc by Canadian radiation oncologists (ros). Methods A 35-item survey was sent by e-mail to Canadian ros. The questions investigated the role of rt, the dose and timing of rt, target delineation, and use of prophylactic cranial irradiation (pci) in limited-stage (ls) and extensive-stage (es) sclc. Results Responses were received from 52 eligible ros. For ls-sclc, staging (98%) and simulation or dosimetric (96%) computed tomography imaging were key determinants of rt suitability. The most common dose and fractionation schedule was 40–45 Gy in 15 once-daily fractions (40%), with elective nodal irradiation performed by 31% of ros. Preferred management of clinical T1/2aN0 sclc favoured primary chemoradiotherapy (64%). For es-sclc, consolidative thoracic rt was frequently offered (88%), with a preferred dose and fractionation schedule of 30 Gy in 10 once-daily fractions (70%). Extrathoracic consolidative rt would not be offered by 23 ros (44%). Prophylactic cranial irradiation was generally offered in ls-sclc (100%) and es-sclc (98%) after response to initial treatment. Performance status, baseline cognition, and pre-pci brain imaging were important patient factors assessed before an offer of pci. Conclusions Canadian ros show practice variation in sclc management. Future clinical trials and national treatment guidelines might reduce variability in the treatment of early-stage disease, optimization of dose and targeting in ls-sclc, and definition of suitability for pci or consolidative rt.

    The completion of continuing professional development (CPD) is mandatory for medical oncologists and trainees (MO&T). Pharmaceutical companies may fund some CPD activities, but there is increasing debate about the potential for conflicts of interest (COI). To assess current practices around funding to attend CPD activities. An electronic survey was distributed to Australian MO&T. The survey asked questions about current practices, institutional policies and perceptions about attending CPD funded by pharmaceutical companies. The design looked at comparing responses between MO&T as well as their understanding of and training around institutional and ethical process. A total of 157 of 653 (24%) responses was received, the majority from MO (76%). Most CPD activities attended by MO&T were self-funded (53%), followed by funding from institutions (19%), pharmaceutical companies (16%) and salary award (16%). Most institutions allowed MO&T to receive CPD funding from professional organisations (104/157, 66%) or pharmaceutical companies (90/157, 57%). A minority of respondents (13/157, 8%) reported that the process to use pharmaceutical funds had been considered by an ethics committee. Although 103/157 (66%) had received pharmaceutical funding for CPD, most (109/157, 69%) reported never receiving training about potential COI. The lack of education was more noticeable among trainees (odds ratio (OR) 8.61, P = 0.02). MO&T acknowledged the potential bias towards a pharmaceutical product (P = 0.05) but believed there was adequate separation between themselves and pharmaceutical companies (P < 0.01). Majority of CPD attended by MO&T is self-funded. There is lack of clarity in institutional policies regarding external funding support for CPD activities. Formal education about potential COI is lacking. © 2017 Royal Australasian College of Physicians.

    The current, now year-long eruption of Mt. St. Helens is remarkable for a variety of reasons. Nearly solid, gas-poor dacite lava is extruding at the surface. Earthquakes are limited to the upper 3 km with most occurring less than 1 km below the surface; no deeper seismicity has been observed. Emissions of SO2, H2S, CO2 are extremely low, suggesting eruption of degassed magma. No direct evidence for mingling of more mafic magma has been observed. We investigated plagioclase crystals in 2004-5 dacite and 1980-86 dacite dome rocks to shed light on the nature and origin of the current magma. Polarized light and Nomarski microscopy in combination with detailed microprobe traverses were used to characterize single plagioclase crystals, focusing on areas near their rims. In addition, we mapped all plagioclase crystals within an area of ~1/3 of each thin section and grouped them according to easily distinguishable mineral features. Although labor-intensive, this new approach was devised to generate data statistically significant enough to compare plagioclase crystal populations of crystal-rich samples. Mappable features within crystals include: i) zones of acicular opx microlitic inclusions (commonly occurring near the rim), ii) resorption surfaces, iii) spatial association of i) and ii). Our key results from the crystal mapping indicate that sequential samples of 2004/5 have remained comparable, but are distinct from 1980-86 dacite dome samples. We interpret this result as strong evidence that the 2004-5 dacite is new magma and not 'left-over' 1980's dacite. The most interesting result from combining compositional profiling with texture is that acicular opx inclusions occur at the lowest observed An content of 40-33 regardless of position within crystal and that overgrowth on resorption surfaces are typically 10-20 mol% higher in An than within opx-rich zones resulting in single to multiple oscillations of An content towards the rim. These features could possibly be

    During the early stages of the 2004-2008 Mount St. Helens eruption, the source process that produced a sustained sequence of repetitive long-period (LP) seismic events also produced impulsive broadband infrasonic signals in the atmosphere. To assess whether the signals could be generated simply by seismic-acoustic coupling from the shallow LP events, we perform finite difference simulation of the seismo-acoustic wavefield using a single numerical scheme for the elastic ground and atmosphere. The effects of topography, velocity structure, wind, and source configuration are considered. The simulations show that a shallow source buried in a homogeneous elastic solid produces a complex wave train in the atmosphere consisting of P/SV and Rayleigh wave energy converted locally along the propagation path, and acoustic energy originating from , the source epicenter. Although the horizontal acoustic velocity of the latter is consistent with our data, the modeled amplitude ratios of pressure to vertical seismic velocity are too low in comparison with observations, and the characteristic differences in seismic and acoustic waveforms and spectra cannot be reproduced from a common point source. The observations therefore require a more complex source process in which the infrasonic signals are a record of only the broadband pressure excitation mechanism of the seismic LP events. The observations and numerical results can be explained by a model involving the repeated rapid pressure loss from a hydrothermal crack by venting into a shallow layer of loosely consolidated, highly permeable material. Heating by magmatic activity causes pressure to rise, periodically reaching the pressure threshold for rupture of the "valve" sealing the crack. Sudden opening of the valve generates the broadband infrasonic signal and simultaneously triggers the collapse of the crack, initiating resonance of the remaining fluid. Subtle waveform and amplitude variability of the infrasonic signals as

    Since its eruption in 1980, Mount St. Helens has experienced multiple inflation-deflation cycles associated with dome building eruptions. During the most recent dome-building episode, which spanned 2004 to 2008, GPS recorded the transition from pre-eruptive inflation to co-eruptive deflation and a final transition back to inflation. Such observations provide important constraints on the timing and mechanics of cyclic magma recharge and extrusion. Currently, the subtle surface deformation signal at St Helens is monitored primarily by ground based geodetic techniques like GPS. Satellite-based InSAR has the potential to substantially augment these techniques by providing spatially continuous, precise measurements of surface displacements, and may also reveal other volcanic or surficial processes too localized to be detected by ground based methods. Traditional interferometry is challenging to apply to volcanoes in the Cascades. Widespread phase decorrelation caused by persistent snow cover and dense vegetation, combined with large, elevation dependent atmospheric phase delays, mask or make deformation signals difficult to detect. By applying StaMPS, a Persistent Scatterers (PS) technique, phase decorrelation is mitigated by utilizing only the pixels with the highest, statistically derived, signal to noise ratio. However, atmospheric water vapor, which delays the radar signal, remains problematic, particularly on the volcano edifice. To assess the bias imposed by the atmosphere, we perform a series of sensitivity tests using a suite of methods including several that rely on the linear or power-law correlation of phase delay to topography and knowledge of the spatial scale of the signal. We also apply methods that calculate wet and dry phase delay from atmospheric reanalysis datasets such as ERA-Interim provided by the ECMWF. SAR data from the ERS, Envisat, and ALOS satellites, along with newer datasets, are processed with these tools to create a time series spanning

  7. Crystallization of microlites during magma ascent: the fluid mechanics of 1980 1986 eruptions at Mount St Helens

    Eruptions of Mount St Helens (Washington, USA) decreased in intensity and explosivity after the main May 18, 1980 eruption. As the post-May 18 eruptions progressed, albitic plagioclase microlites began to appear in the matrix glass, although the bulk composition of erupted products, the phenocryst compositions and magmatic temperatures remained fairly constant. Equilibrium experiments on a Mount St Helens white pumice show that at 160 MPa water pressure and 900°C, conditions deduced for the 8 km deep magma storage zone, the stable plagioclase is An47. The microlites in the natural samples, which are more albitic, had to grow at lower water pressures during ascent. Isothermal decompression experiments reported here demonstrate that a decrease in water pressure from 160 to 2 MPa over four to eight days is capable of producing the albitic groundmass plagioclase and evolved melt compositions observed in post-May 18 1980 dacites. Because groundmass crystallization occurs over a period of days during and after decreases in pressure, microlite crystallization in the Mount St Helens dacites must have occurred during the ascent of each magma batch from a deep reservoir rather than continuously in a shallow holding chamber. This is consistent with data on the kinetics of amphibole breakdown, which require that a significant portion of magma vented in each eruption ascended from a depth of at least 6.5 km (˜160 MPa water pressure) in a matter of days. The size and shape of the microlite population have not been studied because of the small size of the experimental samples; it is possible that the texture continues to mature long after chemical equilibrium is approached. As the temperature, composition, crystal content and water content of magma in the deep reservoir remained approximately constant from May 1980 to at least March 1982, the spectacular decrease in eruption intensity during this period cannot be attributed to changes in viscosity or density of the magma

    The world is experiencing aging of its population. Age-specific incidence rates of cancer are higher and cancer is now recognized as a part of aging. Treating older patients can be challenging. hTe clinical behavior of some tumors changes with age and the aging process itself brings physiological changes leading to decline in the function of organs. It is essential to identify those patients with longer life expectancy, potentially more likely to beneift from aggressive treatment vs. those that are more vulnerable to adverse outcomes. A primary determination when considering therapy for an older cancer patient is a patient’s physiologic, rather than chronologic age. In order to differentiate amongst patients of the same age, it is useful to determine if a patient is ift or frail. Frail older adults have multiple chronic conditions and diffculties maintaining independence. They may be more vulnerable to therapy toxicities, and may not have substantial lasting benefits from therapy. Geriatric assessment (GA) may be used as a tool to determine reversible deifcits and devise treatment strategies to mitigate such deifcits. GA is also used in treatment decision making by clinicians, helping to risk stratify patients prior to potentially high-risk therapy. An important practical aspect of GA is the feasibility of incorporating it into a busy oncology practice. Key considerations in performing the GA include:available resources, patient population, GA tools to use, and who will be responsible for using the GA results and develop care plans. Challenges in implementing GA in clinical practice will be discussed.

    Textural, compositional, and mineralogical data are reported and interpreted for a large population of clinoamphibole phenocrysts in 22 samples from the seven successive dacite spines erupted at Mount St. Helens between October 2004 and January 2006. Despite the uniformity in bulk composition of magma erupted since 2004, there is striking textural and compositional diversity among amphibole phenocrysts and crystal fragments that have grown from, partly dissolved in, or been accidentally incorporated in the new dacite. This study demonstrates that magma erupted throughout the current dome-building episode is the end product of small-scale, thorough mixing of multiple generations of crystal-laden magma. The mixed amphibole population provides important clues to magma conditions within the dacite magma reservoir prior to ascent and, to some extent, the dynamics of mixing and ascent.

    Images from a Web-based camera (Webcam) located 8 km north of Mount St. Helens and a network of remote, telemetered digital cameras were used to observe eruptive activity at the volcano between October 2004 and February 2006. The cameras offered the advantages of low cost, low power, flexibility in deployment, and high spatial and temporal resolution. Images obtained from the cameras provided important insights into several aspects of dome extrusion, including rockfalls, lava extrusion rates, and explosive activity. Images from the remote, telemetered digital cameras were assembled into time-lapse animations of dome extrusion that supported monitoring, research, and outreach efforts. The wide-ranging utility of remote camera imagery should motivate additional work, especially to develop the three-dimensional quantitative capabilities of terrestrial camera networks.

    The eruption of Mount St. Helens from 2004 to 2006 has comprised extrusion of solid lava spines whose growth patterns were shaped by a large space south of the 1980-86 dome that was occupied by the unique combination of glacial ice, concealed subglacial slopes, the crater walls, and relics of previous spines. The eruption beginning September 2004 can be divided (as of April 2006) into five phases: (1) predome deformation and phreatic activity, (2) initial extrusion of spines, (3) recumbent spine growth and repeated breakup, (4) southward extrusion across previous dome debris, and (5) normal faulting of the phase 4 dome to form a depression, a shift to westward extrusion and overthrusting of earlier phase 5 products. Overall, steady spine extrusion gradually slowed from 6 m3/s in November 2004 to 0.6 m3/s in February 2006.

    Current National Comprehensive Cancer Network (NCCN) guidelines recommend thoracic consolidation radiation therapy (TCRT) for patients with Extensive Stage Small Cell Lung Cancer (ES-SCLC) with response to systemic chemotherapy, based on two randomized clinical trials, which varied in patient selection and radiation therapy doses administered. The current pattern of practice among US radiation oncologists is unknown. We have surveyed practicing US radiation oncologist via a short online questionnaire. Respondents' characteristics and their self-rated knowledge base were analyzed for association with their treatment recommendations. We received 473 responses from practicing US radiation oncologists. Over half of respondents were practicing for over 10 years after completing residency training and 70% treated more than 10 lung cancer patients per year. 96% of respondents recommend TCRT for patients with ES-SCLC after systemic chemotherapy. Patient selection and radiation therapy doses vary greatly. High self-rated knowledge of individual clinical trials is associated with lower TCRT recommended doses. Patients treated at academic centers are less likely to receive TCRT than patients treated in private clinics (p=0.0101). Our analysis revealed that among the respondents, there was a very high adherence to current NCCN guidelines, which recommend TCRT for ES-SCLC patients with clinical response to systemic chemotherapy. The great variability in patient selection and radiation therapy doses is concerning and calls for future clinical trials to standardize treatment approaches and improve treatment outcomes among patients with ES-SCLC. Until such data exists and in light of poor long-term survival of patients with ES-SCLC, the shorter and less toxic regimen of 30Gy in 10 fractions should be used as the standard of care and the more aggressive regimens studied on clinical protocols.

    It has been anticipated that physician and parents will be ill prepared or unprepared for the clinical introduction of genome sequencing, making it ethically disruptive. As a part of the Baylor Advancing Sequencing in Childhood Cancer Care study, we conducted semistructured interviews with 16 pediatric oncologists and 40 parents of pediatric patients with cancer prior to the return of sequencing results. We elicited expectations and attitudes concerning the impact of sequencing on clinical decision making, clinical utility, and treatment expectations from both groups. Using accepted methods of qualitative research to analyze interview transcripts, we completed a thematic analysis to provide inductive insights into their views of sequencing. Our major findings reveal that neither pediatric oncologists nor parents anticipate sequencing to be an ethically disruptive technology, because they expect to be prepared to integrate sequencing results into their existing approaches to learning and using new clinical information for care. Pediatric oncologists do not expect sequencing results to be more complex than other diagnostic information and plan simply to incorporate these data into their evidence-based approach to clinical practice, although they were concerned about impact on parents. For parents, there is an urgency to protect their child's health and in this context they expect genomic information to better prepare them to participate in decisions about their child's care. Our data do not support the concern that introducing genome sequencing into childhood cancer care will be ethically disruptive, that is, leave physicians or parents ill prepared or unprepared to make responsible decisions about patient care. © 2015 Wiley Periodicals, Inc.

    Mastectomy and breast conservation therapy (BCT) are equivalent in survival for treatment of early stage breast cancer. This study evaluated the impact of radiation oncologist accessibility on choice of breast conserving surgery (BCS) versus mastectomy, and the appropriate receipt of radiotherapy after BCS. In the National Cancer Institute Survival, Epidemiology, and End Results data base, the authors selected breast cancer cases from 2004 to 2008 with the following criteria: T2N1M0 or less, lobular or ductal histology, and treatment with simple or partial mastectomy. We combined the Health Resources and Services Administration Area Resource File to define average radiation oncologist density (ROD) by county over the same time period. We evaluated tumor characteristics, demographic information, and ROD with respect to BCS rates and receipt of radiation therapy after BCS in univariable and multivariable analyses. In 118,773 cases analyzed, mastectomy was performed 33.2% of the time relative to BCS. After adjustment for demographic and tumor variables, the odds of having BCS versus mastectomy were directly associated with ROD (multiplicative change in odds for a single unit increase in ROD [95% CI] = 1.02 [1.01-1.03]; p < 0.001). Adjuvant radiation therapy was not administered in 28.2% of BCS cases. When adjusting for demographic and tumor variables, the odds of having BCS without adjuvant radiation were inversely associated with ROD (0.95 [0.94-0.97]; p < 0.001). We observed a direct relationship between ROD and BCS rates independent of demographic and tumor variables, and an inverse trend for omission of radiotherapy after BCS. Access to radiation oncologists may represent an important factor in surgical choice and receiving appropriate BCT in early stage breast cancer.

    In oncology, establishing the value of new cancer treatments is challenging. A clear definition of the different perspectives regarding the drivers of innovation in oncology is required to enable new cancer treatments to be properly rewarded for the value they create. The aim of this study was to analyze the views of oncologists, health care policy makers, patients, and the general population regarding the value of new cancer treatments. An exploratory and qualitative study was conducted through structured interviews to assess participants' attitudes toward cost and outcomes of cancer drugs. First, the participants were asked to indicate the minimum survival benefit that a new treatment should have to be funded by the Spanish National Health System (NHS). Second, the participants were requested to state the highest cost that the NHS could afford for a medication that increases a patient's quality of life (QoL) by twofold with no changes in survival. The responses were used to calculate incremental cost-effectiveness ratios (ICERs). The minimum improvement in patient survival means that justified inclusions into the NHS were 5.7, 8.2, 9.1, and 10.4 months, which implied different ICERs for oncologists (€106,000/quality-adjusted life year [QALY]), patients (€73,520/QALY), the general population (€66,074/QALY), and health care policy makers (€57,471/QALY), respectively. The costs stated in the QoL-enhancing scenario were €33,167, €30,200, €26,000, and €17,040, which resulted in ICERs of €82,917/QALY for patients, €75,500/QALY for the general population, €65,000/QALY for oncologists, and €42,600/QALY for health care policy makers, respectively. All estimated ICER values were higher than the thresholds previously described in the literature. Oncologists most valued gains in survival, whereas patients assigned a higher monetary value to treatments that enhanced QoL. Health care policy makers were less likely to pay more for therapeutic

    Volcanic gas observations during the 2004 unrest at Mount St. Helens began with helicopter measurements on September 27 and shifted to fixed-wing aircraft measurements on October 7. Helicopter measurements were done by downwind plume profiling at the crater rim and crater breach, orbiting the dome and cross traversing the top of the dome. Fixed-wing aircraft measurements consisted of profiling the downwind plume as it spilled over the crater rim. Target gases included CO2, SO2, and H2S measured by LI-COR, COSPEC and Interscan analyzers. These measurements defined three periods of volcanic degassing: (a) an initial period of negligible volcanic degassing characterized by scrubbing or sealing-in of all gases; (b) an intermediate period of wet volcanic degassing when gas scrubbing dominated volcanic degassing; and (c) a period of dry volcanic degassing when volcanic degassing exceeded gas scrubbing. Measurements during the September 27-30 period of negligible volcanic degassing showed little or no CO2 above atmospheric levels; SO2 and H2S were not detected. The absence of these gases implies fairly complete gas scrubbing at high water to gas mass ratios (greater than 100) or confinement of the gases by post-1986 sealing of gas transport channel ways. Scrubbing seems likely to have dominated sealing; the high rates of concurrent seismicity and deformation favored reestablishment of transport along fractures, and the unrest followed a period with an unusually large potential for groundwater recharge. No August-September interval since the cessation of dome-building eruptions in 1986 has had heavier rainfall than in 2004, and growth of the crater glacier since 1986 has increased the amount of water available for recharge in late summer. Measurements during the period of wet volcanic degassing that began on October 1 after the first steam and ash eruption showed an increase in the frequency and size of CO2 peaks together with the increasingly common detection of H2S

  19. Evolution of Channels Draining Mount St. Helens: Linking Non-Linear and Rapid, Threshold Responses

    The catastrophic eruption of Mount St. Helens buried the valley of the North Fork Toutle River (NFT) to a depth of up to 140 m. Initial integration of a new drainage network took place episodically by the “filling and spilling” (from precipitation and seepage) of depressions formed during emplacement of the debris avalanche deposit. Channel incision to depths of 20-30 m occurred in the debris avalanche and extensive pyroclastic flow deposits, and headward migration of the channel network followed, with complete integration taking place within 2.5 years. Downstream reaches were converted from gravel-cobble streams with step-pool sequences to smoothed, infilled channels dominated by sand-sized materials. Subsequent channel evolution was dominated by channel widening with the ratio of changes in channel width to changes in channel depth ranging from about 60 to 100. Widening resulted in significant adjustment of hydraulic variables that control sediment-transport rates. For a given discharge over time, flow depths were reduced, relative roughness increased and flow velocity and boundary shear stress decreased non-linearly. These changes, in combination with coarsening of the channel bed with time resulted in systematically reduced rates of degradation (in upstream reaches), aggradation (in downstream reaches) and sediment-transport rates through much of the 1990s. Vertical adjustments were, therefore, easy to characterize with non-linear decay functions with bed-elevation attenuating with time. An empirical model of bed-level response was then created by plotting the total dimensionless change in elevation against river kilometer for both initial and secondary vertical adjustments. High magnitude events generated from the generated from upper part of the mountain, however, can cause rapid (threshold) morphologic changes. For example, a rain-on-snow event in November 2006 caused up to 9 m of incision along a 6.5 km reach of Loowit Creek and the upper NFT. The event

    Frequency-dependent peak-delay times and coda quality factors have been used jointly to separate seismic absorption from scattering quantitatively in Earth media at regional and continental scale; to this end, we measure and map these two quantities at Mount St. Helens volcano. The results show that we can locate and characterize volcanic and geological structures using their unique contribution to seismic attenuation. At 3 Hz a single high-scattering and high-absorption anomaly outlines the debris flows that followed the 1980 explosive eruption, as deduced by comparison with remote sensing imagery. The flows overlay a NNW-SSE interface, separating rocks of significant varying properties down to 2-4 km, and coinciding with the St. Helens Seismic Zone. High-scattering and high-absorption anomalies corresponding to known locations of magma emplacement follow this signature under the volcano, showing the important interconnections between its feeding systems and the regional tectonic boundaries. With frequency increasing from 6 to 18 Hz the NNW-SSE tectonic/feeding trends rotate around an axis centered on the volcano in the direction of the regional-scale magmatic arc (SW-NE). While the aseismic high-scattering region WSW of the volcano shows no evidence of high absorption, the regions of highest-scattering and absorption are consistently located at all frequencies under either the eastern or the south-eastern flank of the volcanic edifice. From the comparison with the available geological and geophysical information we infer that these anomalies mark both the location and the trend of the main feeding systems at depths greater than 4 km.

    Crustal properties beneath Mount St. Helens are investigated using attenuation measurements from an array of 904 cable-free seismographs, referred to as nodes, located within 15 km of the summit crater. Measurements of P wave attenuation were made using 23 controlled explosion sources located 0 - 80 km outside the node array, which provides a well-balanced distribution of source-receiver azimuths and distances. The 500-1000 kg explosive sources were observed regionally, and all explosions produced P waves recorded with signal-to-noise power ratios of >3 dB for >90% of the node array. We estimate relative variations in the path-integrated attenuation parameter, t*, using 2 - 25 Hz spectral ratios of individual node spectra relative to the array median spectrum for each explosion source. For small source-receiver distances (>100). An exception to the previously mentioned trends is that for distances <30 km a ring of 150 nodes closest to the summit crater surrounding the base of the volcanic edifice yield low relative t* estimates ( -0.1s) and high mean envelope amplitudes at all frequencies from 2-25 Hz. The anomalous amplification of these "inner ring" recordings for small offsets could arise from very low impedance in the shallow crust beneath the edifice possibly enhanced by resonance within the edifice. Longer offset measurements will be used for 3D relative attenuation (dQ-1) tomography. We hypothesize that high attenuation (low Q) volumes may be observed at 5-15 km beneath Mount St. Helens where recent controlled source velocity tomography indicates high Vp/Vs. Adding attenuation constraints to recent seismic velocity results will aid estimating properties such as the melt fraction in the upper crustal magma reservoir.

    The surface deformation field measured at volcanic domes provides insights into the effects of magmatic processes, gravity- and gas-driven processes, and the development and distribution of internal dome structures. Here we study short-term dome deformation associated with earthquakes at Mount St. Helens, recorded by a permanent optical camera and seismic monitoring network. We use Digital Image Correlation (DIC) to compute the displacement field between successive images and compare the results to the occurrence and characteristics of seismic events during a 6 week period of dome growth in 2006. The results reveal that dome growth at Mount St. Helens was repeatedly interrupted by short-term meter-scale downward displacements at the dome surface, which were associated in time with low-frequency, large-magnitude seismic events followed by a tremor-like signal. The tremor was only recorded by the seismic stations closest to the dome. We find a correlation between the magnitudes of the camera-derived displacements and the spectral amplitudes of the associated tremor. We use the DIC results from two cameras and a high-resolution topographic model to derive full 3-D displacement maps, which reveals internal dome structures and the effect of the seismic activity on daily surface velocities. We postulate that the tremor is recording the gravity-driven response of the upper dome due to mechanical collapse or depressurization and fault-controlled slumping. Our results highlight the different scales and structural expressions during growth and disintegration of lava domes and the relationships between seismic and deformation signals.

  3. Can Orthopedic Oncologists Predict Functional Outcome in Patients with Sarcoma after Limb Salvage Surgery in the Lower Limb? A Nationwide Study

    Full Text Available Accurate predictions of functional outcome after limb salvage surgery (LSS in the lower limb are important for several reasons, including informing the patient preoperatively and, in some cases, deciding between amputation and LSS. This study aimed to elucidate the correlation between surgeon-predicted and patient-reported functional outcome of LSS in the Netherlands. Twenty-three patients (between six months and ten years after surgery and five independent orthopedic oncologists completed the Toronto Extremity Salvage Score (TESS and the RAND-36 physical functioning subscale (RAND-36 PFS. The orthopedic oncologists made their predictions based on case descriptions (including MRI scans that reflected the preoperative status. The correlation between patient-reported and surgeon-predicted functional outcome was “very poor” to “poor” on both scores (r2 values ranged from 0.014 to 0.354. Patient-reported functional outcome was generally underestimated, by 8.7% on the TESS and 8.3% on the RAND-36 PFS. The most difficult and least difficult tasks on the RAND-36 PFS were also the most difficult and least difficult to predict, respectively. Most questions had a “poor” intersurgeon agreement. It was difficult to accurately predict the patient-reported functional outcome of LSS. Surgeons’ ability to predict functional scores can be improved the most by focusing on accurately predicting more demanding tasks.

    The author has identified the following significant results. Two thermal anomalies, A at 2740 m altitude on the north slope, and B between 2650 and 2750 m altitude on the southwest slope at the contact of the dacite summit dome of Mount St. Helens, Washington were confirmed by aerial infrared scanner surveys between 1971 and 1973. LANDSAT 1 data collection platform 6166, emplaced at site B anomaly, transmitted 482 sets of temperature values in 1973 and 1974, suitable for estimating the differential radiatin emission as 84 W/sq m, approximately equivalent to the Fourier conductive flux of 89 W/sq m in the upper 15 cm below the surface. The differential geothermal flux, including heat loss via evaporation and convection, was estimated at 376 W/sq m. Total energy yield of Mount St. Helens probably ranges between 0.1 and 0.4 x 10 to the 6th power W.

  8. Observations of the eruptions of July 22 and August 7, 1980, at Mount St. Helens, Washington

    The explosive eruptions of July 22 and August 7, 1980, at Mount St. Helens, Wash., both included multiple eruptive pulses. The beginnings of three of the pulses-two on July 22 and one on August 7-were witnessed and photographed. Each of these three began with a fountain of gases and pyroclasts that collapsed around the vent and generated a pyroclastic density flow. Significant vertical-eruption columns developed only after the density flows were generated. This behavior is attributable to either an increase in the gas content of the eruption jet or a decrease in vent radius with time. An increase in the gas content may have occurred as the vent was cleared (by expulsion of a plug of pyroclasts) or as the eruption began to tap deeper, gas-rich magma after first expelling the upper, gas-depleted part of the magma body. An effective decrease of the vent radius with time may have occurred as the eruption originated from progressively deeper levels in the vent. All of these processes-vent clearing; tapping of deeper, gas-rich magma; and effective decrease in vent radius-probably operated to some extent. A 'relief-valve' mechanism is proposed here to account for the occurrence of multiple eruptive pulses. This mechanism requires that the conduit above the magma body be filled with a bed of pyroclasts, and that the vesiculation rate in the magma body be inadequate to sustain continuous eruption. During a repose interval, vesiculation of the magma body would cause gas to flow upward through the bed of pyroclasts. If the rate at which the magma produced gas exceeded the rate at which gas escaped to the atmosphere, the vertical pressure difference across the bed of pyroclastic debris would increase, as would the gas-flow rate. Eventually a gas-flow rate would be achieved that would suddenly diminish the ability of the bed to maintain a pressure difference between the magma body and the atmosphere. The bed of pyroclasts would then be expelled (that is, the relief valve would

    It has long been known that surficial deposits of salts and acids on volcanic ash particles derive from interactions of ash with sulphur and halide species within the eruption plume and volcanic cloud. These compounds are mobilised as ash particles are wetted, and beneficial or detrimental environmental and health impacts may be induced where the most concentrated solutions are produced. However, limited mechanistic understanding of gas-ash interactions currently precludes prediction of the spatial distribution or variation in leachate chemistry and concentration following an eruption. Sampling and leachate analysis of freshly-fallen ash therefore offers the sole method by which such variations can be observed. Previous ash leachate studies often involve a limited number of ash samples, and utilise a 'one-dimensional' analysis that considers variation in terms of absolute distance from the source volcano. Here, we demonstrate that extensive sampling and a 'two-dimensional' analysis can uncover more complex spatial trends. We compiled over 358 leachate compositions from the May 18th 1980 eruption of Mt. St. Helens. Of the water-extracted leachates, only 95 compositions from ash sampled at 45 localities between 35 and 1129 km from the volcano are sufficiently documented to be retrospectively comparable. To consider the effects of intra-deposit variability, we calculated average concentrations of leachate data within 11×22 km grid cells across the region, and defined a data quality parameter to reflect confidence in the derived values. To investigate any dependence of leachate composition on the grain size distribution, we generated an interpolated map of geometric specific surface area variation across the deposit, normalising ash leachate data to the calculated specific surface area at the corresponding sampling location. The data treatment identifies S and Cl enrichments in proximal blast deposits; relatively constant Cl concentrations across the ashfall deposits

    In recent years, the USGS Volcano Hazards Program has worked to implement continuous real-time in situ volcanic gas monitoring at volcanoes in the Cascade Range and Alaska. The main goal of this ongoing effort is to better link the compositions of volcanic gases to other real-time monitoring data, such as seismicity and deformation, in order to improve baseline monitoring and early detection of volcanic unrest. Due to the remote and difficult-to-access nature of volcanic-gas monitoring sites in the Cascades and Alaska, we developed Multi-GAS instruments that can operate unattended for long periods of time with minimal direct maintenance from field personnel. Our Multi-GAS stations measure H2O, CO2, SO2, and H2S gas concentrations, are comprised entirely of commercial off-the-shelf components, and are powered by small solar energy systems. One notable feature of our Multi-GAS stations is that they include a unique capability to perform automated CO2, SO2, and H2S sensor verifications using portable gas standards while deployed in the field, thereby allowing for rigorous tracking of sensor performances. In addition, we have developed novel onboard data-processing routines that allow diagnostic and monitoring data - including gas ratios (e.g. CO2/SO2) - to be streamed in real time to internal observatory and public web pages without user input. Here we present over one year of continuous data from a permanent Multi-GAS station installed in August 2014 in the crater of Mount St. Helens, Washington, and several months of data from a station installed near the summit of Augustine Volcano, Alaska in June 2015. Data from the Mount St. Helens Multi-GAS station has been streaming to a public USGS site since early 2015, a first for a permanent Multi-GAS site. Neither station has detected significant changes in gas concentrations or compositions since they were installed, consistent with low levels of seismicity and deformation.

    An unusual feature of the 2004-6 eruptive activity of Mount St. Helens has been the continuous growth of successive spines that are mantled by thick fault gouge. Fault gouge formation requires, first, solidification of ascending magma within the conduit, then brittle fragmentation and cataclastic flow. We document these processes through field relations, hand samples, and thin-section textures. Field observations show that the gouge zone is typically 1-3 m thick and that it includes cataclasite and, locally, breccia in addition to unconsolidated (true) gouge. The gouge contains multiple slickenside sets oriented subparallel to each other and to the striation direction, as well as surface striations parallel to extrusion direction. Hand specimens show the cataclasite and gouge to be composed of a wide size range of broken dome and wallrock fragments. This grain-size heterogeneity is even more pronounced in thin section, where individual samples contain fragments that span more than four orders of magnitude in size (from more than 10 to less than 10-3 mm).

    A helicopter-mounted thermal imaging radiometer documented the explosive vent-clearing and effusive phases of the eruption of Mount St. Helens in 2004. A gyrostabilized gimbal controlled by a crew member housed the radiometer and an optical video camera attached to the nose of the helicopter. Since October 1, 2004, the system has provided thermal and video observations of dome growth. Flights conducted as frequently as twice daily during the initial month of the eruption monitored rapid changes in the crater and 1980-86 lava dome. Thermal monitoring decreased to several times per week once dome extrusion began. The thermal imaging system provided unique observations, including timely recognition that the early explosive phase was phreatic, location of structures controlling thermal emissions and active faults, detection of increased heat flow prior to the extrusion of lava, and recognition of new lava extrusion. The first spines, 1 and 2, were hotter when they emerged (maximum temperature 700-730°C) than subsequent spines insulated by as much as several meters of fault gouge. Temperature of gouge-covered spines was about 200°C where they emerged from the vent, and it decreased rapidly with distance from the vent. The hottest parts of these spines were as high as 500-730°C in fractured and broken-up regions. Such temperature variation needs to be accounted for in the retrieval of eruption parameters using satellite-based techniques, as such features are smaller than pixels in satellite images.

    Volcanic eruptions and other infrequent, large-scale natural disturbances pose challenges and opportunities for public-land managers. In the days and weeks preceding an eruption, there can be considerable uncertainty surrounding the magnitude and areal extent of eruptive effects. At the same time, public and media interest in viewing developing events is high and concern for public safety on the part of local land managers and public safety officials is elevated. Land managers and collaborating Federal, State, and local officials must decide whether evacuations or restrictions to public access are necessary, the appropriate level of advance preparation, and how best to coordinate between overlapping jurisdictions. In the absence of a formal Federal or State emergency declaration, there is generally no identified source of supplemental funding for emergency-response preparation or managing extraordinary public and media response to developing events. In this chapter, we examine responses to escalating events that preceded the 2004 Mount St. Helens eruption and changes in public perception during the extended period of the largely nonexplosive, dome-building eruption that followed. Lessons learned include the importance of maintaining up-to-date emergency-response plans, cultivating close working relationships with collaborating agencies, and utilizing an organized response framework that incorporates clearly defined roles and responsibilities and effective communication strategies.

    Purpose: Social media and mobile technology are transforming the way in which young physicians are learning and practicing medicine. The true impact of such technologies has yet to be evaluated. Methods and Materials: We performed a nationwide cross-sectional survey to better assess how young radiation oncologists used these technologies. An online survey was sent out between April 24, 2013, and June 1, 2013. All residents attending the 2013 radiation oncology French summer course were invited to complete the survey. Logistic regressions were performed to assess predictors of use of these tools in the hospital on various clinical endpoints. Results: In all, 131 of 140 (93.6%) French young radiation oncologists answered the survey. Of these individuals, 93% owned a smartphone and 32.8% owned a tablet. The majority (78.6%) of the residents owning a smartphone used it to work in their department. A total of 33.5% had more than 5 medical applications installed. Only 60.3% of the residents verified the validity of the apps that they used. In all, 82.9% of the residents had a social network account. Conclusions: Most of the residents in radiation oncology use their smartphone to work in their department for a wide variety of tasks. However, the residents do not consistently check the validity of the apps that they use. Residents also use social networks, with only a limited impact on their relationship with their patients. Overall, this study highlights the irruption and the risks of new technologies in the clinical practice and raises the question of a possible regulation of their use in the hospital.

    Recent randomized controlled data suggest that neoadjuvant chemotherapy (NACT) with interval debulking (ID) may produce similar overall survival and progression free survival compared to standard primary cytoreduction followed by chemotherapy. The object of our study was to assess current patterns of care among members of the Society of Gynecologic Oncologists (SGO), specifically collating their opinions on and use of NACT for advanced stage ovarian cancer. A 20-item questionnaire was sent to all working e-mail addresses of SGO members (n=1137). The data was collected and analyzed using descriptive statistics with commercially available online survey software. The Chi-square test for independence was used to determine differences in responses between groups. Of 339 (30%) responding members, most rarely employ NACT, with 60% of respondents using NACT in less than 10% of advanced stage ovarian cancer cases. Respondents did not consider available evidence sufficient to justify NACT followed by ID (82%), nor did most think it should be preferred (74%). Sixty-two percent of respondents thought it was impossible to accurately predict preoperatively whether an optimal cytoreduction is possible. Thirty-nine percent believed that women with bulky upper abdominal disease on preoperative imaging would benefit from NACT versus primary debulking. If gross disease were found at ID, 43% would continue to treat with IV chemotherapy, and 42% would place an IP port if optimally cytoreduced. When ID reveals microscopic disease, 51% would continue IV treatment and the remaining IP therapy. Eighty-six percent of the respondents believed that both biological and surgical factors determine patient outcomes. The majority of responding SGO members do not treat patients with NACT followed by ID. Currently available studies of NACT/ID have been insufficient to convince most gynecologic oncologists to incorporate it into practice. Our results provide a benchmark against which further research

  19. Modeling the dynamic response of a crater glacier to lava-dome emplacement: Mount St Helens, Washington, USA

    Price, Stephen F.; Walder, Joseph S.

    2007-01-01

    The debris-rich glacier that grew in the crater of Mount St Helens after the volcano's cataclysmic 1980 eruption was split in two by a new lava dome in 2004. For nearly six months, the eastern part of the glacier was squeezed against the crater wall as the lava dome expanded. Glacier thickness nearly doubled locally and surface speed increased substantially. As squeezing slowed and then stopped, surface speed fell and ice was redistributed downglacier. This sequence of events, which amounts to a field-scale experiment on the deformation of debris-rich ice at high strain rates, was interpreted using a two-dimensional flowband model. The best match between modeled and observed glacier surface motion, both vertical and horizontal, requires ice that is about 5 times stiffer and 1.2 times denser than normal, temperate ice. Results also indicate that lateral squeezing, and by inference lava-dome growth adjacent to the glacier, likely slowed over a period of about 30 days rather than stopping abruptly. This finding is supported by geodetic data documenting dome growth.

  20. Using Satellite Data to Characterize the Temporal Thermal Behavior of an Active Volcano: Mount St. Helens, WA

    2006-01-01

    ASTER thermal infrared data over Mt. St Helens were used to characterize its thermal behavior from Jun 2000 to Feb 2006. Prior to the Oct 2004 eruption, the average crater temperature varied seasonally between -12 and 6 C. After the eruption, maximum single-pixel temperature increased from 10 C (Oct 2004) to 96 C (Aug 2005), then showed a decrease to Feb 2006. The initial increase in temperature was correlated with dome morphology and growth rate and the subsequent decrease was interpreted to relate to both seasonal trends and a decreased growth rate/increased cooling rate, possibly suggesting a significant change in the volcanic system. A single-pixel ASTER thermal anomaly first appeared on Oct 1, 2004, eleven hours after the first eruption - 10 days before new lava was exposed at the surface. By contrast, an automated algorithm for detecting thermal anomalies in MODIS data did not trigger an alert until Dec 18. However, a single-pixel thermal anomaly first appeared in MODIS channel 23 (4 um) on Oct 13, 12 days after the first eruption - 2 days after lava was exposed. The earlier thermal anomaly detected with ASTER data is attributed to the higher spatial resolution (90 m) compared with MODIS (1 m) and the earlier visual observation of anomalous pixels compared to the automated detection method suggests that local spatial statistics and background radiance data could improve automated detection methods.

  1. Generation of pyroclastic flows and surges by hot-rock avalanches from the dome of Mount St. Helens volcano, USA

    Several hot-rock avalanches have occurred during the growth of the composite dome of Mount St. Helens, Washington between 1980 and 1987. One of these occurred on 9 May 1986 and produced a fan-shaped avalanche deposit of juvenile dacite debris together with a more extensive pyroclastic-flow deposit. Laterally thinning deposits and abrasion and baking of wooden and plastic objects show that a hot ash-cloud surge swept beyond the limits of the pyroclastic flow. Plumes that rose 2-3 km above the dome and vitric ash that fell downwind of the volcano were also effects of this event, but no explosion occurred. All the facies observed originated from a single avalanche. Erosion and melting of craterfloor snow by the hot debris caused debris flows in the crater, and a small flood that carried juvenile and other clasts north of the crater. A second, broadly similar event occured in October 1986. Larger events of this nature could present a significant volcanic hazard. ?? 1988 Springer-Verlag.

  2. The effect of consumers and mutualists of Vaccinium membranaceum at Mount St. Helens: dependence on successional context.

    Suann Yang

    Full Text Available In contrast to secondary succession, studies of terrestrial primary succession largely ignore the role of biotic interactions, other than plant facilitation and competition, despite the expectation that simplified interaction webs and propagule-dependent demographics may amplify the effects of consumers and mutualists. We investigated whether successional context determined the impact of consumers and mutualists by quantifying their effects on reproduction by the shrub Vaccinium membranaceum in primary and secondary successional sites at Mount St. Helens (Washington, USA, and used simulations to explore the effects of these interactions on colonization. Species interactions differed substantially between sites, and the combined effect of consumers and mutualists was much more strongly negative for primary successional plants. Because greater local control of propagule pressure is expected to increase successional rates, we evaluated the role of dispersal in the context of these interactions. Our simulations showed that even a small local seed source greatly increases population growth rates, thereby balancing strong consumer pressure. The prevalence of strong negative interactions in the primary successional site is a reminder that successional communities will not exhibit the distribution of interaction strengths characteristic of stable communities, and suggests the potential utility of modeling succession as the consequence of interaction strengths.

    The 2004 reawakening of Mount St. Helens quickly caught the attention of government agencies as well as the international news media and the public. Immediate concerns focused on a repeat of the catastrophic landslide and blast event of May 18, 1980, which remains a vivid memory for many individuals. Within several days of the onset of accelerating seismicity, media inquiries increased exponentially. Personnel at the U.S. Geological Survey, the Pacific Northwest Seismic Network, and the Gifford Pinchot National Forest soon handled hundreds of press inquiries and held several press briefings per day. About one week into the event, a Joint Information Center was established to help maintain a consistent hazard message and to provide a centralized information source about volcanic activity, hazards, area closures, and media briefings. Scientists, public-affairs specialists, and personnel from emergency-management, health, public-safety, and land-management agencies answered phones, helped in press briefings and interviews, and managed media access to colleagues working on science and safety issues. For scientists, in addition to managing the cycle of daily fieldwork, challenges included (1) balancing accurate interpretations of data under crisis conditions with the need to share information quickly, (2) articulating uncertainties for a variety of volcanic scenarios, (3) minimizing scientific jargon, and (4) frequently updating and effectively distributing talking points. Success of hazard information management during a volcanic crisis depends largely on scientists’ clarity of communication and thorough preplanning among interagency partners. All parties must commit to after-action evaluation and improvement of communication plans, incorporating lessons learned during each event.

    We report the results of in-situ laser ablation ICP–MS analyses of anorthite content, trace-element (Li, Ti, Sr, Ba, La, Pr, Ce, Nd, Eu, Pb) concentrations, and Pb-isotope compositions in plagioclase from eight dome-dacite samples collected from the 2004-5 eruption of Mount St. Helens and, for comparison, from three dome samples from 1981-85. For 2004-5 samples, plagioclase phenocrysts range in composition from An30 to An80, with the majority An42-An65. With the exception of Li, the range of trace-element abundances in plagioclase phenocrysts is largely constant in material erupted between October 2004 and April 2005 and is broadly consistent with the 1983-85 dome samples. Anomalously high Li contents in the early stage of the eruption are thought to reflect addition of Li to the upper part of the magma chamber immediately before eruption (within ~1 year) by transfer of an alkali-enriched, exsolved vapor from deep within the magma chamber. Other trace elements show significant correlations (at >99 percent confidence limits) with anorthite content in plagioclase phenocrysts--Ba, light rareearth elements (LREE), and Pb show positive correlations, whereas Ti and Sr correlate negatively. Variations in plagioclase-melt partitioning as a function of anorthite content cannot explain trace-element variations--in particular predicting trends for Ti and Sr opposite to those observed. A simple model involving closed-system fractional crystallization of plagioclase + hypersthene + amphibole + oxides largely reproduces the observed trends. The model requires no gain or loss of plagioclase and is consistent with the lack of europium anomalies in bulk dacite samples. Analytical traverses within individual plagioclase phenocrysts support this model but also point to a diversity of melt compositions present within the magma storage zone in which plagioclase crystallized.

  6. Swift snowmelt and floods (lahars) caused by great pyroclastic surge at Mount St Helens volcano, Washington, 18 May 1980

    Waitt, R.B.

    1989-01-01

    The initial explosions at Mount St. Helens, Washington, on the moring of 18 May 1980 developed into a huge pyroclastic surge that generated catastrophic floods off the east and west flanks of the volcano. Near-source surge deposits on the east and west were lithic, sorted, lacking in accretionary lapilli and vesiculated ash, not plastered against upright obstacles, and hot enough to char wood - all attributes of dry pyroclastic surge. Material deposited at the surge base on steep slopes near the volcano transformed into high-concentration lithic pyroclastic flows whose deposits contain charred wood and other features indicating that these flows were hot and dry. Stratigraphy shows that even the tail of the surge had passed the east and west volcano flanks before the geomorphically distinct floods (lahars) arrived. This field evidence undermines hypotheses that the turbulent surge was itself wet and that its heavy components segregated out to transform directly into lahars. Nor is there evidence that meters-thick snow-slab avalanches intimately mixed with the surge to form the floods. The floods must have instead originated by swift snowmelt at the base of a hot and relatively dry turbulent surge. Impacting hot pyroclasts probably transferred downslope momentum to the snow surface and churned snow grains into the surge base. Melting snow and accumulating hot surge debris may have moved initially as thousands of small thin slushflows. As these flows removed the surface snow and pyroclasts, newly uncovered snow was partly melted by the turbulent surge base; this and accumulating hot surge debris in turn began flowing, a self-sustaining process feeding the initial flows. The flows thus grew swiftly over tens of seconds and united downslope into great slushy ejecta-laden sheetfloods. Gravity accelerated the floods to more than 100 km/h as they swept down and off the volcano flanks while the snow component melted to form great debris-rich floods (lahars) channeled into

  7. The controls and consequences of substrate entrainment by pyroclastic density currents at Mount St Helens, Washington (USA)

    Evidence in the deposits from the May 18, 1980 eruption at Mount St Helens demonstrates that pyroclastic density currents (PDCs) produced during the afternoon of the eruption became intermittently erosive. Using detailed componentry and granulometry we constrain the sources for lithic blocks in the deposits and identify deposits from PDCs that became locally erosive. The componentry of the lithics in the fall deposits is used as a proxy for vent erosion and assumed to represent the starting componentry for PDCs prior to entrainment from any other source. We find little evidence in the PDC deposits nearest to the base of the volcano for entrainment from the steep flanks; however, significant evidence indicates that PDCs eroded into the debris avalanche hummocks, suggesting that entrainment is favored as PDCs interact with highly irregular topography. Evidence for locally entrained material downstream from debris avalanche hummocks decreases with height in the outcrop, suggesting that less entrainment occurs as local relief decreases and upstream topography is buried. The prevalence of lithofacies containing locally entrained material at the base of unit contacts and only 10s of meters downstream from debris avalanche hummocks suggests that the majority of entrainment occurs at or near the head of the current. Occasionally, entrained material is located high above unit contacts and deposited well after the initial head of the current is inferred to have passed, indicating that entrainment can occur during periods of non-deposition either from the semi-sustained body of the current or from a pulsating current. Additionally, self-channelization of PDCs, either by levee deposition or scouring into earlier PDC deposits, occurs independently of interaction with topographic obstacles and can affect carrying capacity and runout distance. While we begin to explore the mechanisms and effects of erosion on current dynamics, additional laboratory and numerical studies are

  8. The Stars Belong to Everyone: The rhetorical practices of astronomer and science writer Dr. Helen Sawyer Hogg (1905--1993)

    Cahill, Maria J.

    Astronomer and science writer Dr. Helen Sawyer Hogg (University of Toronto) reached a variety of audiences through different rhetorical forms. She communicated to her colleagues through her scholarly writings; she reached out to students and the public through her Toronto Star newspaper column entitled "With the Stars," which she authored for thirty years; she wrote The Stars Belong to Everyone , a book that speaks to a lay audience; she hosted a successful television series entitled Ideas ; and she delivered numerous speeches at scientific conferences, professional women's associations, school programs, libraries, and other venues. Adapting technical information for different audiences is at the heart of technical communication, and Sawyer Hogg's work exemplifies adaptation as she moves from writing for the scientific community (as in her articles on globular cluster research) to science writing for lay audiences (as in her newspaper column, book, and script for her television series). Initially she developed her sense of audience through a male perspective informed largely by her scholarly work with two men (Harlow Shapley and her husband, Frank Hogg) as well as the pervasive masculine culture of academic science. This dissertation situates Sawyer Hogg in what is slowly becoming a canon of technical communication scholarship on female scientists. Toward this end, I discuss how she rhetorically engaged two different audiences, one scholarly and one popular, how Sawyer Hogg translated male dominated scientific rhetoric to writing for the public, and how science writing helped her achieve her professional goals. Complementing the archival research in addressing the questions of this study, I employ social construction analysis (also known as the social perspective) for my research methodology. She was ahead of her time and embodied the social perspective years before its definition as a rhetorical concept. In short, my study illuminates one scientific woman's voice

  9. “Knowing Things in Common”: Sheila Jasanoff and Helen Longino on the Social Nature of Knowledge

    Directory of Open Access Journals (Sweden)

    Jaana Eigi

    2014-06-01

    Full Text Available In her analysis of the politics of biotechnology, Sheila Jasanoff argued that modern democracy cannot be understood without an analysis of the ways knowledge is created and used in society. She suggested calling these ways to “know things in common” civic epistemologies. Jasanoff thus approached knowledge as fundamentally social. The focus on the social nature of knowledge allows drawing parallels with some developments in philosophy of science. In the first part of the paper, I juxtapose Jasanoff’s account with the philosopher Helen Longino’s approach. Longino argued that objectivity of scientific knowledge is made possible by the social nature of knowledge production. In the process of community-wide discussion, claims that are not intersubjectively acceptable are rejected and communally acceptable knowledge emerges. Longino called this knowledge-creating critical dialogue transformative. I suggest that Longino’s account can be seen as providing epistemological support for the civic epistemologies Jasanoff described. They are capable of producing knowledge in the normative philosophical sense of the word to the degree that they are able to support this transformative critical dialogue. In the second part of the paper, I explore in the light of Longino’s criteria for effective knowledge-productive dialogue one of the controversies in biotechnology policy that Jasanoff analysed. I suggest that Longino’s criteria allow identifying some fundamental obstacles for initiating and maintaining this kind of responsive critical dialogue and that the controversy can be seen as caused by inability to overcome these obstacles. In such a case, the controversy signals an epistemic failure as well as a failure of democratic policy.

  10. Insights into the Mount St. Helens Magma Plumbing System from Coarse-grained, Crystal-rich Enclaves

    Co-magmatic plutonic enclaves provide information about the conditions of magmatic storage and magmatic processes. The deposits of Mount St. Helens contain a variety of coarse-grained, crystal-rich enclaves, dominantly derived from the Tertiary basement. However, zircons in two enclaves returned ages of 5-108 ka (n=29) and 45-486 ka (n=16), overlapping with zircon ages from the volcanics. From textures and mineralogy, we define five enclave types, interpreted as crystal mush from the current magmatic system: hbl-gabbros with ad-cumulate structure (type 1), dioritic meso-cumulates with partly decomposed minerals (type 2), and dioritic rocks enriched in incompatible elements (type 3). All three occur in Pine Creek dacite domes ( 2900 BP), and comprise amphibole, plagioclase, orthopyroxene and oxides (±apatite and zircon) with variable amounts of residual melt. A heterad-cumulate (type 4) from 1980 dacite consists of olivine, plagioclase, ortho- and clinopyroxene (±oxides and apatite) with poikilitic overgrowth of amphibole. Inclusions of pyroxene-plagioclase-oxide-bearing crystal aggregates (type 5) are found in Late Pine Creek andesites ( 2600 BP). Compositional similarity between amphiboles in type 1 and 2 cumulates and those from their dacitic host rock suggests these cumulates co-erupted with their extracted melt. Modelled trace element compositions of coexisting liquids indicate that the high-Al amphibole cores (up to 14.5 wt.% Al2O3) crystallized from andesitic melts that are parental to the dacites. In contrast, andesites erupted during the same eruptive period lack amphibole suggesting drier/shallower crystallization resulting in the predominant fractionation of pyroxene seen in type 5 inclusions. Different cumulates represent residues from basaltic andesitic to dacitic melts. Mid to upper crustal pressures determined via barometry are consistent with crystallization within the bottle-shaped magma reservoir ( 7-20 km) imaged during the recent activity.

  11. Liftoff of the 18 May 1980 surge of Mount St. Helens (USA) and the deposits left behind

    The distance that ground-hugging pyroclastic density currents travel is limited partly by when they reverse buoyancy and liftoff into the atmosphere. It is not clear, however, what deposits are left behind by lofting flows. One current that was seen to liftoff was the surge erupted from Mount St. Helens on the morning of 18 May 1980. Before lofting, it had leveled a large area of thick forest (the blowdown zone). The outer edge of the devastated area—where trees were scorched but left standing (the scorched zone)—is where the surge is thought to have lifted off. Deposits in the outer parts of the blowdown and in the scorched zone were examined at 32 sites. The important finding is that the laterally moving surge traveled through the scorched zone, and hence, the change in tree damage does not mark the runout distance of the surge. Buoyancy reversal and liftoff are thus not preserved in the deposits where the surge lofted upwards. We propose, based on interpretation of eyewitness accounts and the impacts of the surge on trees and vehicles, that the surge consisted of a faster, dilute "overcurrent" and a slower "undercurrent," where most of the mass (and heat) was retained. Reasonable estimates for flow density and velocity show that dynamic pressure of the surge (i.e., its ability to topple trees) peaked near the base of the overcurrent. We propose that where the overcurrent began to liftoff, the height of peak dynamic pressure rose above the trees and stopped toppling them. The slower undercurrent continued forward, however, scorching trees, but lacked the dynamic pressure needed to topple them. Grain-size variations argue that it slowed from ˜30 m s-1 when it entered the scorched zone to ˜3 m s-1 at the far end.

    Pyroclastic density currents (flows and surges) are one of the most deadly hazards associated with volcanic eruptions. Understanding what controls how far such currents will travel, and how their dynamic pressure evolves, could help mitigate their hazards. The distance a ground hugging, pyroclastic density current travels is partly limited by when it reverses buoyancy and lifts off into the atmosphere. The 1980 blast surge of Mount St. Helens offers an example of a current seen to lift off. Before lofting, it had traveled up to 20 km and leveled more than 600 km3 of thick forest (the blowdown zone). The outer edge of the devastated area - where burned trees that were left standing (the singe zone) - is where the surge is thought to have lifted off. We recently examined deposits in the outer parts of the blowdown and in the singe zone at 32 sites. The important finding is that the laterally moving surge travelled into the singe zone, and hence the change in tree damage does not mark the run out distance of the ground hugging surge. Eyewitness accounts and impacts on trees and vehicles reveal that the surge consisted of a fast, dilute "overcurrent" and a slower "undercurrent", where most of the mass (and heat) was retained. Reasonable estimates for flow density and velocity show that dynamic pressure of the surge (i.e., its ability to topple trees) peaked near the base of the overcurrent. We propose that when the overcurrent began to lift off, the height of peak dynamic pressure rose above the trees and stopped toppling them. The slower undercurrent continued forward, burning trees but it lacked the dynamic pressure needed to topple them. Grain-size variations argue that it slowed from 30 m/s when it entered the singe zone to 3 m/s at the far end. Buoyancy reversal and liftoff are thus not preserved in the deposits where the surge lofted upwards.

  13. After the disaster: the hydrogeomorphic, ecological, and biological responses to the 1980 eruption of Mount St. Helens, Washington

    2009-01-01

    The 1980 eruption of Mount St. Helens caused instantaneous landscape disturbance on a grand scale. On 18 May 1980, an ensemble of volcanic processes, including a debris avalanche, a directed pyroclastic density current, voluminous lahars, and widespread tephra fall, abruptly altered landscape hydrology and geomorphology, and created distinctive disturbance zones having varying impacts on regional biota. Response to the geological and ecological disturbances has been varied and complex. In general, eruption-induced alterations in landscape hydrology and geomorphology led to enhanced stormflow discharge and sediment transport. Although the hydrological response to landscape perturbation has diminished, enhanced sediment transport persists in some basins. In the nearly 30 years since the eruption, 350 million (metric) tons of suspended sediment has been delivered from the Toutle River watershed to the Cowlitz River (roughly 40 times the average annual preeruption suspended-sediment discharge of the Columbia River). Such prodigious sediment loading has wreaked considerable socioeconomic havoc, causing significant channel aggradation and loss of flood conveyance capacity. Significant and ongoing engineering efforts have been required to mitigate these problems. The overall biological evolution of the eruption-impacted landscape can be viewed in terms of a framework of survivor legacies. Despite appearances to the contrary, a surprising number of species survived the eruption, even in the most heavily devastated areas. With time, survivor “hotspots” have coalesced into larger patches, and have served as stepping stones for immigrant colonization. The importance of biological legacies will diminish with time, but the intertwined trajectories of geophysical and biological successions will influence the geological and biological responses to the 1980 eruption for decades to come.

    Purpose: We surveyed how radiation oncologists think about and incorporate a palliative cancer patient’s life expectancy (LE) into their treatment recommendations. Methods and Materials: A 41-item survey was e-mailed to 113 radiation oncology attending physicians and residents at radiation oncology centers within the Boston area. Physicians estimated how frequently they assessed the LE of their palliative cancer patients and rated the importance of 18 factors in formulating LE estimates. For 3 common palliative case scenarios, physicians estimated LE and reported whether they had an LE threshold below which they would modify their treatment recommendation. LE estimates were considered accurate when within the 95% confidence interval of median survival estimates from an established prognostic model. Results: Among 92 respondents (81%), the majority were male (62%), from an academic practice (75%), and an attending physician (70%). Physicians reported assessing LE in 91% of their evaluations and most frequently rated performance status (92%), overall metastatic burden (90%), presence of central nervous system metastases (75%), and primary cancer site (73%) as “very important” in assessing LE. Across the 3 cases, most (88%-97%) had LE thresholds that would alter treatment recommendations. Overall, physicians’ LE estimates were 22% accurate with 67% over the range predicted by the prognostic model. Conclusions: Physicians often incorporate LE estimates into palliative cancer care and identify important prognostic factors. Most have LE thresholds that guide their treatment recommendations. However, physicians overestimated patient survival times in most cases. Future studies focused on improving LE assessment are needed.

    Surgery is the standard of care in stage I non-small cell lung cancer (NSCLC), but stereotactic ablative radiotherapy (SABR) is increasingly used to treat patients at high-risk for surgical complications. We studied which patient- and clinician-related characteristics influenced treatment recommendations. A binary choice experiment with hypothetical cases was conducted. Cases varied on five patient-related characteristics: patient age, Chronic Obstructive Pulmonary Disease Global Initiative for Chronic Obstructive Lung Disease (COPD GOLD) score, Charlson co-morbidity index, World Health Organization performance status (WHO-PS) and patient treatment preference (surgery/SABR). Clinician characteristics were recorded. Responses were analyzed using generalized linear mixed models. 126 clinicians completed the survey. All patient-related characteristics, the clinician speciality, and whether clinicians considered outcomes of surgery comparable to SABR, significantly influenced treatment recommendations. Pulmonologists were most influenced by WHO-PS and comorbidity, whereas comorbidity and age had greatest influence on radiation oncologists and surgeons. Clinicians were less influenced by stated patient preference and COPD GOLD score. Limited consistency was observed in treatment recommendations. This study suggests that more efforts are needed to develop uniform approaches for making treatment recommendations, and also to incorporate patient preferences when making treatment decisions for stage I NSCLC.

    The 2004-5 eruption of Mount St. Helens exhibited sustained, near-equilibrium behavior characterized by nearly steady extrusion of a solid dacite plug and nearly periodic occurrence of shallow earthquakes. Diverse data support the hypothesis that these earthquakes resulted from stick-slip motion along the margins of the plug as it was forced incrementally upward by ascending, solidifying, gas-poor magma. I formalize this hypothesis with a mathematical model derived by assuming that magma enters the base of the eruption conduit at a steady rate, invoking conservation of mass and momentum of the magma and plug, and postulating simple constitutive equations that describe magma and conduit compressibilities and friction along the plug margins. Reduction of the model equations reveals a strong mathematical analogy between the dynamics of the magma-plug system and those of a variably damped oscillator. Oscillations in extrusion velocity result from the interaction of plug inertia, a variable upward force due to magma pressure, and a downward force due to the plug weight. Damping of oscillations depends mostly on plug-boundary friction, and oscillations grow unstably if friction exhibits rate weakening similar to that observed in experiments. When growth of oscillations causes the extrusion rate to reach zero, however, gravity causes friction to reverse direction, and this reversal instigates a transition from unstable oscillations to self-regulating stick-slip cycles. The transition occurs irrespective of the details of rate-weakening behavior, and repetitive stick-slip cycles are, therefore, robust features of the system’s dynamics. The presence of a highly compressible elastic driving element (that is, magma containing bubbles) appears crucial for enabling seismogenic slip events to occur repeatedly at the shallow earthquake focal depths (8 N. These results imply that the system’s self-regulating behavior is not susceptible to dramatic change--provided that the

    The working group "Young DEGRO" (yDEGRO) was established in 2014 by the German Society of Radiation Oncology (DEGRO). We aimed to assess the current situation of young radiation oncologists, medical physicists and radiation biologists. An online survey that included 52 questions or statements was designed to evaluate topics related to training, clinical duties and research opportunities. Using the electronic mailing list of the DEGRO and contact persons at university hospitals in Germany as well as at four hospitals in Switzerland and Austria, young professionals employed in the field of radiation oncology were invited to participate in the survey. A total of 260 responses were eligible for analysis. Of the respondents 69 % had a professional background in medicine, 23 % in medical physics and 9 % in radiation biology. Median age was 33 years. There was a strong interest in research among the participants; however a clear separation between research, teaching and routine clinical duties was rarely present for radiation oncologists and medical physicists. Likewise, allocated time for research and teaching during regular working hours was often not available. For radiation biologists, a lack of training in clinical and translational research was stated. This survey details the current state of education and research opportunities in young radiation oncologists, medical physicists and radiation biologists. These results will form the basis for the future working program of the yDEGRO.

  3. Discrete Slip, Amorphous Silica and Pore Structure of Slickensided Gouge Layers in 2004-2006 Mt. St. Helens Lava Domes

    Spines of dacite lava formed during the 2004-2006 Mt. St. Helens (MSH) effusion event are enveloped by extrusion gouges created during upward movement of crystallized magma. Multiple slickenside sets form one of the most distinctive feature types within this gouge carapace. Macroscopically, slickenside surfaces are seen to be composite features composed of discrete slip surfaces in Y- and R-shear orientations. In general, the spacing between the slip surfaces decreases toward the outer, exposed slickensided surface until they appear to coalesce. Slickensides are formed in association with all MSH spines, unlike some other fault rock fabrics within the gouge; therefore, their morphology can be inferred to be independent of syn-faulting residence time. As a significant record of the extrusion process, the MSH slickensides have been characterized by analytical scanning/transmission electron microscopy (STEM) to elucidate the mechanisms of energy dissipation and material transport. At the scale of these observations, the individual surfaces within a slickenside set comprise comminution bands (10-20 μm wide), each bounded by a discrete slip surface. The internal structure of these shear bands consists of a consistent sense of decreasing grain size toward the slip surface away and away from the spire core; grain size is routinely less than 100nm within the bands. The 1-5 μm wide slip layers that bound comminution bands are variously composed of amorphous silica or polycrystalline aggregates of sub-100nm grain size plagioclase, k-feldspar and quartz. Grain aggregates in the slip layer form an extended fabric parallel to the displacement direction, creating a "flow" foliation at edges of the shears. Specific to the slip bands are nano-scale pores, often silica-filled, whose circular cross-sections indicate the presence of fluids throughout slickenside formation. It is contended that the development of discrete slip surfaces is consistent with formation of the gouge by

The EM data identified water-saturated rocks from the surface to the detection limit (100 - 200 m) in discreet zones at Mt. Rainier and Mt Adams and over the entire summit region at Mt. Baker. At Mt. St. Helens, perched aquifers are identified in the 1980 avalanche deposits as well as in older, thick breccia or avalanche deposits. The modeled distribution of alteration and pore fluids helps identify likely sources for future alteration-related debris flows and clearly shows that debris flow hazard studies on altered volcanoes are greatly enhanced by magnetic, EM and gravity data.

    A steady-state, one-dimensional, and nonhomogeneous two-phase flow model was developed for the prediction of local flow properties in volcanic conduits. The model incorporates the effects of relative velocity between the phases and for the variable magma viscosity. The resulting set of nonlinear differential equations was solved by a stiff numerical solver and the results were verified with the results of basaltic fissure eruptions obtained by a homogeneous two-phase flow model, before applying the model to the eruptions of Mt. St. Helens and Vesuvius volcanoes. This verification, and a study of the sensitivity of several modeling parameters, proved effective in establishing the confidence in the predicted nonequilibrium results of flow distribution in the conduits when the mass flow rate is critical or maximum. The application of the model to the plinian eruptions of Mt. St. Helens on May 18, 1980, and Vesuvius in AD 79, demonstrates the sensitivity of the magma discharge rate and distributions of pressure, volumetric fraction, and velocities of phases, on the hydrous magma viscosity feeding the volcanic conduits. Larger magma viscosities produce smaller mass discharge rates (or greater conduit diameters), smaller exit pressures, larger disequilibrium between the phases, and larger difference between the local lithostatic and fluid pressures in the conduit. This large pressure difference occurs when magma fragments and may cause a rupture of the conduit wall rocks, producing a closure of the conduit and cessation of the volcanic eruption, or water pouring into the conduit from underground aquifers leading to phreatomagmatic explosions. The motion of the magma fragmentation zone along a conduit during an eruption can be caused by the varying viscosity of magma feeding the volcanic conduit and may cause intermittent phreatomagmatic explosions during the plinian phases as different underground aquifers are activated at different depths. The variation of magma

    This field trip will provide an introduction to several fascinating features of Mount St. Helens. The trip begins with a rigorous hike of about 15 km from the Johnston Ridge Observatory (9 km north-northeast of the crater vent), across the 1980 Pumice Plain, to Windy Ridge (3.6 km northeast of the crater vent) to examine features that document the dynamics and progressive emplacement of pyroclastic flows. The next day, we examine classic tephra outcrops of the past 3,900 years and observe changes in thickness and character of these deposits as we traverse their respective lobes. We examine clasts in the deposits and discuss how the petrology and geochemistry of Mount St. Helens deposits reveal the evolution of the magmatic system through time. We also investigate the stratigraphy of the 1980 blast deposit and review the chronology of this iconic eruption as we travel through the remains of the blown-down forest. The third day is another rigorous hike, about 13 km round trip, climbing from the base of Windy Ridge (elevation 1,240 m) to the front of the Crater Glacier (elevation 1,700 m). En route we examine basaltic andesite and basalt lava flows emplaced between 1,800 and 1,700 years before present, a heterolithologic flow deposit produced as the 1980 blast and debris avalanche interacted, debris-avalanche hummocks that are stranded on the north flank and in the crater mouth, and shattered dacite lava domes that were emplaced between 3,900 and 2,600 years before present. These domes underlie the northern part of the volcano. In addition, within the crater we traverse well-preserved pyroclastic-flow deposits that were emplaced on the crater floor during the summer of 1980, and a beautiful natural section through the 1980 deposits in the upper canyon of the Loowit River.Before plunging into the field-trip log, we provide an overview of Mount St. Helens geology, geochemistry, petrology, and volcanology as background. The volcano has been referred to as a

    COMMENTS FOR PROFESSOR BARRIE R. CASSILETH: I have enjoyed reading the two issues of The Oncologist I've received so far. I would like to make some comments on Dr. Cassileth's article. I'm a pediatric oncologist at the National University Hospital in Singapore. Singapore is an interesting place to study people, as ours is a multi-racial country, with 75% Chinese, 16% Malays and 7% Indians, plus a significant expatriate population (Americans, British, Australians, etc.). I've been very interested in the influence of different ethnic and social backgrounds on how our patients cope with their diseases, especially families of children with cancer. We did a survey of 20 patients and found that nine of the children are given bird's nest, nine are given ginseng, and five had been given Chinese medicinal herbs. I've been doing a bit of literature search, and found that there's some evidence that Chinese medicine may help to "boost the immune system," enhancing the ability of the patients to undergo conventional cancer therapy. However, most traditional Chinese medicine practitioners would recommend that these patients continue with their "Western treatment." I have no objection to patients availing themselves of these complementary approaches, though we do not encourage it either. We are in the unenviable situation of trying to help and give advice to our patients about things about which we know little, as there is so little hard evidence. Of all the literature I've gone through so far, I find the recent Choices in Healing by Michael Lerner (MIT Press) the most helpful. PROFESSOR CASSILETH'S RESPONSE: Dr. Quah raises a number of important issues. I share his interest in the influence of culture and ethnicity on how patients and families cope with cancer. The cultural meaning of malignant disease, in fact, has long shaped not only individual reactions, but also how societies have approached research, treatment, and communication. In the United States, for example, the word

    Rapid onset of unrest at Mount St. Helens on September 23, 2004, initiated an uninterrupted lava-dome-building eruption that continues to the time of writing this overview (spring 2006) for a volume of papers focused on this eruption. About three weeks of intense seismic unrest and localized surface uplift, punctuated by four brief explosions, constituted a ventclearing phase, during which there was a frenzy of media attention and considerable uncertainty regarding the likely course of the eruption. The third week exhibited lessened seismicity and only minor venting of steam and ash, but rapid growth of the uplift, or welt, south of the 1980-86 lava dome proceeded as magma continued to push upward. Crystalrich dacite (~65 weight percent SiO2) lava first appeared at the surface on October 11, 2004, beginning the growth of a complex lava dome of uniform chemical composition accompanied by persistent but low levels of seismicity, rare explosions, low gas emissions, and frequent rockfalls. Petrologic studies suggest that the dome lava is chiefly of 1980s vintage, but with an admixed portion of new dacite. Alternatively, it may derive from a part of the magma chamber not tapped by 1980s eruptions. Regardless, detailed investigations of crystal chemistry, melt inclusions, and isotopes reveal a complex magmatic history. Largely episodic extrusion between 1980 and 1986 produced a relatively symmetrical lava dome composed of stubby lobes. In contrast, continuous extrusion at mean rates of about 5 m3/s in autumn 2004 to 3/s in early 2006 has produced an east-west ridge of three mounds with total volume about equal to that of the old dome. During much of late 2004 to summer 2005, a succession of spines, two recumbent and one steeply sloping and each mantled by striated gouge, grew to nearly 500 m in length in the southeastern sector of the 1980 crater and later disintegrated into two mounds. Since then, growth has been concentrated in the southwestern sector, producing a

    Helen Flanders Dunbar (1902-1959) was a physician, medieval and Renaissance scholar, theologian, and founder of the American Psychosomatic Society and its journal Psychosomatic Medicine. Her contributions are not currently well known but deserve recognition from all those involved or interested in the dialogue between medicine and spirituality. This essay explores Dunbar's personal history and professional achievements. It focuses particular attention on a feminist perspective regarding her life and work. It will conclude with a discussion of how biography, as an art form, transforms both author and audience. This essay was originally presented as the Second Annual J.R.

    Johns Hopkins has been a leader in paediatric cardiology for over 85 years. In the 1940s, Dr Helen Taussig began training fellows in paediatric cardiology at Johns Hopkins at a time when the diagnosis and treatment of CHD were in the earliest stage. Under her leadership, the fellowship developed a strong foundation that has continued to evolve to meet the current needs of learners and educators. In the current era, the Johns Hopkins programme implements the current theories of adult education and actively engages our fellows in learning as well as teaching. The programme uses techniques such as flipped classroom, structured case-based small-group learning, observed and structured clinical examination, simulations, and innovative educational technology. These strategies combined with our faculty and rich history give our fellows a unique educational experience.

    The stochastic loss of energy measured using the later portion of seismic recordings (coda) can be used to image and monitor geomorphology in volcanoes, once appropriate sensitivity kernels for the application of attenuation tomography have been developed. The use of this advanced seismic method with GIS/InSAR techniques is an unexplored field, which is receiving increasing attention in volcano-seismology. By using this integrated approach we can image structure and monitor dynamics of the debris flow that followed the 1980 explosive eruption of Mount St. Helens (US) volcano at resolution similar to that of remote sensing data, and depths of Italy, the results provide a novel perspective on the links between deep fluid migration and surface structures. The implications of the proposed approach on volcano monitoring are evident.

    The May 18th, 1980 eruption of Mount St. Helens (MSH) produced multiple pyroclastic density currents (PDCs), burying the area north of the volcano under 10s of meters of deposits. Detailed measurements of recently exposed strata from these PDCs provide substantial insight into the dynamics of concentrated currents including inferences on particle-particle interactions, current mobility due to sedimentation fluidization and internal pore pressure, particle support mechanisms, the influence of surface roughness and the conditions that promote substrate erosion and self-channelization. Four primary flow units are identified along the extensive drainage system north of the volcano. The PDCs associated with Units I and II likely occurred during the pre-climactic, waxing phase of the eruption. These currents flowed around and filled in the hummocky topography left behind by the earlier debris avalanche, leaving the massive to diffusely-stratified deposits of Units I and II. The deposits of both Units I and II are generally massive in low lying areas and stratified in areas of high surface roughness, suggesting that surface roughness enhanced basal shear stress within the flow boundary. Units III and IV are associated with the climactic phase of the eruption, which produced the most voluminous and wide-spread PDCs. Both flow units are characteristically massive and enriched in vent-derived lithic blocks. However, an increase in the proportion and size of lithic blocks is found (1) downstream of debris avalanche hummocks, suggesting the PDCs flowed over and around debris avalanche hummocks and were energetic enough to locally entrain accidental lithics from the hummocks and transport them tens of meters downstream, and (2) within large channels cut by later PDCs into earlier PDC deposits, suggesting self-channelization of the flows increased the carrying capacity of the subsequent channelized currents. Unit III is massive, poorly sorted, and shows little to no evidence of

    The May 18th, 1980 eruption of Mount St. Helens (MSH) produced multiple pyroclastic density currents (PDCs), burying the area north of the volcano under 10s of meters of deposits. Detailed measurements of recently exposed strata from these PDCs provide substantial insight into the dynamics of concentrated currents including inferences on particle-particle interactions, current mobility due to sedimentation fluidization and internal pore pressure, particle support mechanisms, the influence of surface roughness and the conditions that promote substrate erosion and self-channelization. Four primary flow units are identified along the extensive drainage system north of the volcano. Each flow unit has intricate vertical and lateral facies changes and complex cross-cutting relationships away from source. Each flow unit is an accumulation from an unsteady but locally sustained PDC or an amalgamation of several PDC pulses. The PDCs associated with Units I and II likely occurred during the pre-climactic, waxing phase of the eruption. These currents flowed around and filled in the hummocky topography, leaving the massive to diffusely-stratified deposits of Units I and II. The deposits of both Units I and II are generally more massive in low lying areas and more stratified in areas of high surface roughness, suggesting that surface roughness enhanced basal shear stress within the flow boundary. Units III and IV are associated with the climactic phase of the eruption, which produced the most voluminous and wide-spread PDCs. Both flow units are characteristically massive and enriched in vent-derived lithic blocks. These currents flowed over and around the debris avalanche deposits, as evidenced by the erosion of blocks from the hummocks. Unit III is massive, poorly sorted, and shows little to no evidence of elutriation or segregation of lithics and pumice, suggesting a highly concentrated current where size-density segregation was suppressed. Unit IV shows similar depositional

    Results from chemical and isotopic analyses of water and gas collected between 2002 and 2016 from sites on and around Mount St. Helens are used to assess magmatic degassing related to the 2004-2008 eruption. During 2005 the chemistry of hot springs in The Breach of Mount St. Helens showed no obvious response to the eruption, and over the next few years, changes were subtle, giving only slight indications of perturbations in the system. By 2010 however, water chemistry, temperatures, and isotope compositions (δD and δ18O) clearly indicated some inputs of volatiles and heat associated with the eruption, but the changes were such that they could be attributed to a pre-existing, gas depleted magma. An increase of ~ 1.5‰ in the δ13C values of dissolved carbon in the springs was noted in 2006 and continued through 2009, a change that was mirrored by a similar shift in δ13C-CO2 in bubble gas emissions. These changes require input of a new source of carbon to the hydrothermal system and provide clear evidence of CO2 from an undegassed body of magma. Rising trends in 3He/4He ratios in gas also accompanied the increases in δ13C. Since 2011 maximum RC/RA values are ≥ 6.4 and are distinctly higher than 5 samples collected between 1986 and 2002, and provide additional evidence for some involvement of new magma as early as 2006, and possibly earlier, given the unknown time needed for CO2 and He to traverse the system and arrive at the springs.

    Purpose: Peritumoral edema may harbor sarcoma cells. The extent of suspicious edema (SE) included in the treatment volume is subject to clinical judgment, balancing the risk of missing tumor cells with excess toxicity. Our goal was to determine variability in SE delineation by sarcoma radiation oncologists (RO). Methods and Materials: Twelve expert ROs were provided with T1 gadolinium and T2-weighted MR images of 10 patients with high-grade extremity soft-tissue sarcoma. Gross tumor volume, clinical target volume (CTV)3cm (3 cm longitudinal and 1.5 cm radial margin), and CTV2cm (2 cm longitudinal and 1 cm radial margin) were contoured by a single observer. Suspicious peritumoral edema, defined as abnormal signal on T2 images, was independently delineated by all 12 ROs. Contouring agreement was analyzed using the simultaneous truth and performance level estimation (STAPLE) algorithm and kappa statistics. Results: The mean volumes of GTV, CTV2cm, and CTV3cm were, respectively, 130 cm{sup 3} (7-413 cm{sup 3}), 280 cm{sup 3} and 360 cm{sup 3}. The mean consensus volume computed using the STAPLE algorithm at 95% confidence interval was 188 cm{sup 3} (24-565 cm{sup 3}) with a substantial overall agreement corrected for chance (mean kappa = 0.71; range: 0.32-0.87). The minimum, maximum, and mean volume of SE (excluding the GTV) were 4, 182, and 58 cm{sup 3} (representing a median of 29% of the GTV volume). The median volume of SE not included in the CTV2cm and in the CTV3cm was 5 and 0.3 cm{sup 3}, respectively. There were 3 large tumors with >30 cm{sup 3} of SE not included in the CTV3cm volume. Conclusion: Despite the fact that SE would empirically seem to be a more subjective volume, a substantial or near-perfect interobserver agreement was observed in SE delineation in most cases with high-grade soft-tissue sarcomas of the extremity. A median of 97% of the consensus SE is within the CTV2cm (99.8% within the CTV3cm). In a minority of cases, however, significant

    Purpose: To measure concordance among genitourinary radiation oncologists in using the National Cancer Institute Common Toxicity Criteria (NCI CTC) and Radiation Therapy Oncology Group (RTOG) grading scales to grade rectal bleeding. Methods and Materials: From June 2013 to January 2014, a Web-based survey was sent to 250 American and Canadian academic radiation oncologists who treat prostate cancer. Participants were provided 4 case vignettes in which patients received radiation therapy and developed rectal bleeding and were asked for management plans and to rate the bleeding according to NCI CTC v.4 and RTOG late toxicity grading (scales provided). In 2 cases, participants were also asked whether they would send the patient for colonoscopy. A multilevel, random intercept modeling approach was used to assess sources of variation (case, respondent) in toxicity grading to calculate the intraclass correlation coefficient (ICC). Agreement on a dichotomous grading scale (low grades 1-2 vs high grades 3-4) was also assessed, using the κ statistic for multiple respondents. Results: Seventy-two radiation oncologists (28%) completed the survey. Forty-seven (65%) reported having either written or been principal investigator on a study using these scales. Agreement between respondents was moderate (ICC 0.52, 95% confidence interval [CI] 0.47-0.58) when using NCI CTC and fair using the RTOG scale (ICC 0.28, 95% CI 0.20-0.40). Respondents who chose an invasive management were more likely to select a higher toxicity grade (P<.0001). Using the dichotomous scale, we observed moderate agreement (κ = 0.42, 95% CI 0.40-0.44) with the NCI CTC scale, but only slight agreement with the RTOG scale (κ = 0.19, 95% CI 0.17-0.21). Conclusion: Low interrater reliability was observed among radiation oncologists grading rectal bleeding using 2 common scales. Clearer definitions of late rectal bleeding toxicity should be constructed to reduce this variability and avoid ambiguity in both

    Full Text Available ResumenEste trabajo aborda la cuestión de los cultos ofrecidos de manera voluntaria a los monarcas helenísticos y a Dea Roma por parte de las póleis del oriente griego. Se analiza desde una perspectiva histórica la cuestión de los isothéoi timaí (estatua, sacrificios y fiesta ofrecidos a los reyes helenísticos y se tiene en cuenta la creación de un original culto a Roma con similares características. En ese sentido, nos interesa indagar acerca del papel que estas prácticas cultuales tuvieron en el establecimiento y desarrollo de las relaciones diplomáticas entre las póleis y los êthne griegos con los reyes helenísticos y Roma. Estos dos tipos de cultos muestran continuidades que revelan el carácter estratégico y pragmático de estas prácticas sociales. Creemos que el estudio de este fenómeno aportará elementos para redimensionar el rol activo de las póleis en época helenística en un contexto internacional signado en un primer momento por el dominio de las monarquías helenísticas y luego por Roma. Abstract:This work deals with the cults voluntarily offered to the Hellenistic monarchs and Dea Roma by the poleis of the Greek East. The issue of the isotheoi timai (statue, sacrifices and festivals offered to the Hellenistic kings is analyzed from a historical point of view; and the creation of an original cult of Rome with similar characteristics is also taken into account. In this sense, we are interested in investigating the role that these cultural practices had in the establishment and development of the diplomatic relations between the Greek poleis and ethne with the Hellenistic kings and Rome. These two kinds of cults show continuities which reveal the strategic and pragmatic condition of these social practices. We believe that the study of this phenomenon will provide elements to set the active role of the poleis in the Hellenistic period within an international context characterized by the supremacy of the Hellenistic

    A numerical simulation of the ground-water flow system in the Castle Lake debris dam, calibrated to data from the 1991 and 1992 water years, was used to estimate factors of safety against heave and internal erosion. The Castle Lake debris dam, 5 miles northwest of the summit of Mount St. Helens, impounds 19,000 acre-ft of water that could pose a flood hazard in the event of a lake breakout. A new topographic map of the Castle Lake area prior to the 1980 eruption of Mount St. Helens was prepared and used to calculate the thickness of the debris avalanche deposits that compose the dam. Water levels in 22 piezometers and discharges from seeps on the dam face measured several times per year beginning in 1990 supplemented measurements in 11 piezometers and less frequent seep discharge measurements made since 1983. Observations in one group of piezometers reveal heads above the land surface and head gradients favoring upward flow that correspond to factors of safety only slightly greater than 2. The steady-state ground-water flow system in the debris dam was simulated using a threedimensional finite difference computer program. A uniform, isotropic model having the same shape as the dam and a hydraulic conductivity of 1.55 ft/day simulates the correct water level at half the observation points, but is in error by 10 ft or more at other points. Spatial variations of hydraulic conductivity were required to calibrate the model. The model analysis suggests that ground water flows in both directions between the debris dam and Castle Lake. Factors of safety against heave and internal erosion were calculated where the model simulated upward flow of ground water. A critical gradient analysis yields factors of safety as low as 2 near the piezometers where water level observations indicate low factors of safety. Low safety factors are also computed near Castle Creek where slumping was caused by a storm in January, 1990. If hydraulic property contrasts are present in areas of the

    Among global convergent margins, the Cascade arc (Pacific Northwest, North America) has an atypically warm thermal profile due to the young age of the subducting ocean crust (≤10 Ma) and slow rate of subduction (3.5 cm/yr) in this region. Slab dehydration is thus expected to occur at relatively shallow subduction depths, resulting in high fluid fluxes in the mantle wedge below the forearc, with minimal addition of volatiles directly beneath the main volcanic front. Across-arc trends in magmatic volatiles should be most visible within particularly wide (E-W) portions of the active volcanic arc, such as are observed in Southern Washington, Central Oregon, and Northern California. As part of an ongoing study aimed at constraining variations in magmatic volatiles using monogenetic cinder cones across the Southern Washington Cascades, we analyzed the H2O and CO2 contents of olivine-hosted melt inclusions in basaltic scoria (Bu tephra) from the Castle Creek eruptive period (2.0-1.7 ka) of Mount St. Helens (MSH). The defining feature of this period is the first appearance of mafic magma at the surface, which initiated the modern Mount St. Helens and its variety of rock compositions (Mullineaux, 1996). Andesite, dacite, and basalt all were erupted during Castle Creek time, producing pyroclastic flows, surges, and tephra as well as lava flows. Our initial results show pre-eruptive H2O contents of 0.4-1.3 wt. % H2O and CO2 values that are below detection (<25-50 ppm). The morphology of the olivine crystals and their melt inclusions indicate relatively rapid crystallization. Given the low CO2 values, we conclude that the melt inclusions trapped partially degassed melts at relatively low pressure in a volcanic conduit or shallow storage reservoir. MSH represents the western extent of a stretch of volcanism extending ~100 km to the east; MSH magmas are thus expected to have high volatile contents relative to the other volcanic centers at this latitude.

    The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980–1986 and 2004–2008. More than three decades after the emplacement of the 1980 debris avalanche, high sediment production persists in the North Fork Toutle River basin, which drains the northern flank of the volcano. Because this sediment increases the risk of flooding to downstream communities on the Toutle and Cowlitz Rivers, the U.S. Army Corps of Engineers (USACE), under the direction of Congress to maintain an authorized level of flood protection, built a sediment retention structure on the North Fork Toutle River in 1989 to help reduce this risk and to prevent sediment from clogging the shipping channel of the Columbia River. From September 16–20, 2009, Watershed Sciences, Inc., under contract to USACE, collected high-precision airborne lidar (light detection and ranging) data that cover 214 square kilometers (83 square miles) of Mount St. Helens and the upper North Fork Toutle River basin from the sediment retention structure to the volcano's crater. These data provide a digital dataset of the ground surface, including beneath forest cover. Such remotely sensed data can be used to develop sediment budgets and models of sediment erosion, transport, and deposition. The U.S. Geological Survey (USGS) used these lidar data to develop digital elevation models (DEMs) of the study area. DEMs are fundamental to monitoring natural hazards and studying volcanic landforms, fluvial and glacial geomorphology, and surface geology. Watershed Sciences, Inc., provided files in the LASer (LAS) format containing laser returns that had been filtered, classified, and georeferenced. The USGS produced a hydro-flattened DEM from ground-classified points at Castle, Coldwater, and Spirit Lakes. Final results averaged about five laser last

    Major element, trace element, and volatile concentrations in 187 glassy melt inclusions and 25 groundmass glasses from the 1980-86 eruption of Mount St. Helens are presented, together with 103 analyses of touching FE-Ti oxide pairs from the same samples. These data are used to evaluate the temporal evolution of the magmatic plumbing system beneath the volcano during 1980-86 and so provide a framework in which to interpret analyses of melt inclusions from the current (2004-2006) eruption. Major and trace element concentrations of all melt inclusions lie at the high SiO2 end of the data array defined by eruptive products of the late Quaternary age from Mount St. Helens. For several major and trace elements, the glasses define a trend that is oblique to the whole-rock trend, indicating that different mineral assemblages were responsible for the two trends. The whole-rock trend can be ascribed to differentiation of hydrous basaltic parents in a deep-seated magma reservoir, probably at depths great enough to stabilize garnet. In contrast, the glass trends were generated by closed-system crystallization of the phenocryst and microlite mineral assemblages at low pressures. The dissolved H2O content of the melt inclusions from 1980-86, as measured by the ion microprobe, ranges from 0 to 6.7 wt. percent, with the highest values obtained from the plinian phase of May 18, 1980. Water contents decrease with increasing SiO2, consistent with decompression-driven crystallization. Preliminary data for dissolved CO2 in melt inclusions from the May 18 plinian phase from August 7, 1980, indicate that XH2O in a vapor phase was approximately constant at 0.80, irrespective of H2O content, suggestive of closed-system degassing with a high bubble fraction or gas streaming through the subvolcanic system.

    Physics-based models of volcanic eruptions can directly link magmatic processes with diverse, time-varying geophysical observations, and when used in an inverse procedure make it possible to bring all available information to bear on estimating properties of the volcanic system. We develop a technique for inverting geodetic, extrusive flux, and other types of data using a physics-based model of an effusive silicic volcanic eruption to estimate the geometry, pressure, depth, and volatile content of a magma chamber, and properties of the conduit linking the chamber to the surface. A Bayesian inverse formulation makes it possible to easily incorporate independent information into the inversion, such as petrologic estimates of melt water content, and yields probabilistic estimates for model parameters and other properties of the volcano. Probability distributions are sampled using a Markov-Chain Monte Carlo algorithm. We apply the technique using GPS and extrusion data from the 2004–2008 eruption of Mount St. Helens. In contrast to more traditional inversions such as those involving geodetic data alone in combination with kinematic forward models, this technique is able to provide constraint on properties of the magma, including its volatile content, and on the absolute volume and pressure of the magma chamber. Results suggest a large chamber of >40 km3 with a centroid depth of 11–18 km and a dissolved water content at the top of the chamber of 2.6–4.9 wt%.

    The anatomy of the clitoris is described in human anatomy textbooks. Some researchers have proposal and divulged a new anatomical terminology for the clitoris. This paper is a revision of the anatomical terms proposed by Helen O'Connell, Emmanuele Jannini, and Odile Buisson. Gynecologists, sexual medicine experts, and sexologists should spread certainties for all women, not hypotheses or personal opinions, they should use scientific terminology: clitoral/vaginal/uterine orgasm, G/A/C/U spot orgasm, and female ejaculation, are terms that should not be used by sexologists, women, and mass media. Clitoral bulbs, clitoral or clitoris-urethrovaginal complex, urethrovaginal space, periurethral glans, Halban's fascia erogenous zone, vaginal anterior fornix erogenous zone, genitosensory component of the vagus nerve, and G-spot, are terms used by some sexologists, but they are not accepted or shared by experts in human anatomy. Sexologists should define have sex, make love, the situation in which the orgasm happens in both partners with or without a vaginal intercourse. PMID:21941661

    Mount St. Helens began erupting in late 2004 following an 18 year quiescence. Swarms of repeating earthquakes accompanied the extrusion of a mostly solid dacite dome over the next 4 years. In some cases the waveforms from these earthquakes evolved slowly, likely reflecting changes in the properties of the volcano that affect seismic wave propagation. We use coda-wave interferometry to quantify small changes in seismic velocity structure (usually <1%) between two similar earthquakes and employed waveforms from several hundred families of repeating earthquakes together to create a continuous function of velocity change observed at permanent stations operated within 20 km of the volcano. The high rate of earthquakes allowed tracking of velocity changes on an hourly time scale. Changes in velocity were largest near the newly extruding dome and likely related to shallow deformation as magma first worked its way to the surface. We found strong correlation between velocity changes and the inverse of real-time seismic amplitude measurements during the first 3 weeks of activity, suggesting that fluctuations of pressure in the shallow subsurface may have driven both seismicity and velocity changes. Velocity changes during the remainder of the eruption likely result from a complex interplay of multiple effects and are not well explained by any single factor alone, highlighting the need for complementary geophysical data when interpreting velocity changes.

    We analyze a group of 6073 low-frequency earthquakes recorded during a week-long temporary deployment of broadband seismometers at distances of less than 3 km from the crater at Mount St. Helens in September of 2006. We estimate the seismic moment (M0) and spectral corner frequency (f0) using a spectral ratio approach for events with a high signal-to-noise (SNR) ratio that have a cross-correlation coefficient of 0.8 or greater with at least five other events. A cluster analysis of cross-correlation values indicates that the group of 421 events meeting the SNR and cross-correlation criteria forms eight event families that exhibit largely self-similar scaling. We estimate the M0 and f0 values of the 421 events and calculate their static stress drop and scaled energy (ER/M0) values. The estimated values suggest self-similar scaling within families, as well as between five of eight families (i.e.,  and  constant). We speculate that differences in scaled energy values for the two families with variable scaling may result from a lack of resolution in the velocity model. The observation of self-similar scaling is the first of its kind for such a large group of low-frequency volcanic tectonic events occurring during a single active dome extrusion eruption.

    This paper documents the numerical formulations, thermochemical data base, and possible applications of computer programs, SOLVGAS and GASWORKS, for calculating multicomponent chemical equilibria in gas-solid-liquid systems. SOLVGAS and GASWORKS compute simultaneous equilibria by solving simultaneously a set of mass balance and mass action equations written for all gas species and for all gas-solid or gas-liquid equilibria. Examples of gas-evaporation-from-magma and precipitation-with-cooling calculations for volcanic gases collected from Mount St. Helens are shown. -from Authors

    A fanning technique based on a simplistic physical model provided a classification algorithm for mixture landscapes. Results of applications to LANDSAT inventory of 1.5 million acres of forest land in Northern Maine are presented. Signatures for potential deer year habitat in New Hampshire were developed. Volcanic activity was monitored in Nicaragua, El Salvador, and Guatemala along with the Mt. St. Helens eruption. Emphasis in the monitoring was placed on the remote sensing of SO2 concentrations in the plumes of the volcanoes.

    The dome-building eruption at Mount St. Helens has occurred through glacial ice and snow that would be expected to substantially affect the character of the eruption. Nevertheless, the role of water in the eruption to date has not always been clear. For example, on March 8, 2005, a half-hour-long tephra blast sent a plume to a maximum of ~9 km above the vent (based on pilot reports); seismicity and plume heights were greatest during the first ~10 minutes, then persisted for another ~15 minutes at a lower level before the eruption stopped. Tephra volume within 5 km2 downwind of the vent was ~5x104 m3 DRE, but trace amounts were reported at least to Ellensburg, WA (150 km NE), suggesting a total areal coverage >5,000 km2 and total volume >1x105 m3. Assuming that most of this material was expelled in the first ten minutes and had a density of 2500 kg/m3, the mass flow rate (M) during the vigorous phase was >~4x105 kg/s. The tephra, composed primarily of non-pumiceous broken and decrepitated dome rock, could have been expelled either by groundwater and steam at relatively modest (boiling-point) temperatures, or by magmatic gas at much higher temperatures. The high plume, however, suggested significant buoyancy, perhaps driven by temperatures closer to magmatic. To assess the effect of magmatic heat on plume height, we employ a 1-D steady volcanic plume model that uses specified vent diameter, exit velocity, eruption temperature, mass fractions of gas and added external water, and profiles of atmospheric temperature and humidity, to calculate plume height and plume properties as a function of elevation. The model considers the enthalpy of equilibrium water condensation and of ice formation. Model results show that, under atmospheric temperature and humidity profiles measured near Mount St. Helens on the afternoon of March 8, 2005, a plume height (h) of 7-9 km could have developed with eruption temperatures (T) as low as 100° C, provided the mass fraction of water vapor

    The 18 May 1980 eruption of Mount St. Helens started with a lateral blast that fed a pyroclastic surge, which then uplifted to form a co-blast plume. Thirty minutes later, Plinian activity started at the vent and fluctuated in intensity for ~9 h. The resulting fallout deposit, documented to > 600 km from vent, presents some striking features: (1) displacement of the overall deposit to the north of the vent, (2) a secondary thickness and mass maximum at ~300 km from vent, (3) a total grain size distribution dominated by fine ash (62 wt % of the deposit < 63 µm), and (4) individual grain size distributions that vary dramatically in the crosswind direction from strongly bimodal in the south to skewed unimodal in the north. Results from a new deconvolution of the individual grain size distributions show that they are a combination of a coarse subpopulation that decreases in size with distance from vent and a constant fine subpopulation with a mean of ˜15 µm. Relative proportions of each subpopulation vary asymmetrically in the crosswind directions, with the fine subpopulation preponderant toward the north and the coarse one dominating the south of the deposit, both reach their absolute maxima in mass on the deposit axis. Componentry analyses of selected samples show that blast-derived material is greatly enriched toward the north of the deposit. These results indicate that the co-blast plume dispersed fine-grained material over great distances and dominated the fine subpopulation. Comparison with reanalysis data of atmospheric wind fields and satellite images of the spreading ash cloud suggests contrasting ash transport and depositional processes for the (early) co-blast plume and the (later) vent-derived Plinian plumes. The co-blast plume is displaced to the north; it had a high overshoot height, and eastward dispersion via strong winds low in the stratosphere (~10-15 km). The Plinian plumes were lower and dispersed most of the material to the southeast as the

    A helicopter-mounted forward-looking infrared radiometer (FLIR) was deployed by the Cascades Volcano Observatory (CVO) during the initial phases of renewed volcanic activity at Mount St. Helens (MSH). The instrument began collecting data on October 1, 2004, and was flown twice daily (weather permitting) during the first month of the eruption. Thermal infrared (TIR) data collected during the first seven flight-days imaged the 1980 crater floor, phreatic explosion pits, and ash cooling on the surface. However, it was not until October 11, 2004, that the FLIR data confirmed a lava body was present at the surface. After the initial extrusion of new dome rock, subsequent surveys from the helicopter-mounted and a hand-held FLIR were used to model its rise rate and volume. During the pre-extrusive phase of the eruption, the FLIR camera commonly imaged the same regions of the older lava dome and portions of the uplifted crater floor. Qualitative changes in the heat flux were noted at the time, but the rapid escalation in activity and long days of field work precluded a more quantitative approach. In an effort to understand the early phases of the eruption process, FLIR data from times prior to October 11 have been re-analyzed. Data from these days were ideal because of good weather conditions, relative stability of ground surface features, and a minimal amount of plume within the crater itself. Two distinct geomorphic features identifiable in each day's data were clipped from the full resolution images. The data were first corrected for distance, atmospheric pathlength energy, and surface emissivity and then converted to radiant flux. Assuming the radiative heat output at these locations is related to the conductive heat loss from the magma body below, heat balance models can be employed to estimate the depth of the magma. Assumptions that must be made for such an approach include: 1) the average pre-eruptive temperature for dacitic magma; 2) the contribution of convective

    The 1980 eruption of Mount St. Helens produced a massive landslide and consequent pyroclastic currents, deposits of which blocked the outlet to Spirit Lake. Without an outlet, the lake began to rise, threatening a breaching of the blockage and release of a massive volume of water. To mitigate the hazard posed by the rising lake and provide an outlet, in 1984–1985 the U.S. Army Corps of Engineers bored a 2.6-km (8,500-ft) long tunnel through a bedrock ridge on the western edge of the lake. Locally, the tunnel crosses weak rock along faults, and external pressures in these weak zones have caused rock heave and support failures, which have necessitated periodic major repairs. During its more than 30-year lifetime, the tunnel has maintained the level of Spirit Lake at a safe elevation. The lake approaches its maximum safe operating level only when the tunnel closes for repair. The most recent major repair in early 2016 highlights the need for a reliable outlet that does not require repeated and expensive interventions and extended closures. The U.S. Forest Service, U.S. Army Corps of Engineers, and U.S. Geological Survey developed, reviewed, and analyzed an array of options for a long-term plan to remove the threat of catastrophic failure of the tunnel. In this report, we (1) provide background on natural hazards that can affect existing and alternative infrastructure; (2) evaluate the potential for tunnel failure and consequent breaching of the blockage posed by the current tunnel infrastructure; (3) evaluate potential consequences to downstream communities and infrastructure in the event of a catastrophic breaching of the blockage; (4) evaluate potential risks associated with alternative lake outlets; and (5) identify data and knowledge gaps that need to be addressed to fully evaluate options available to management.

    Long-period (LP, 0.5-5 Hz) seismicity, observed at volcanoes worldwide, is a recognized signature of unrest and eruption. Cyclic LP "drumbeating" was the characteristic seismicity accompanying the sustained dome-building phase of the 2004-2008 eruption of Mount St. Helens (MSH), WA. However, together with the LP drumbeating was a near-continuous, randomly occurring series of tiny LP seismic events (LP "subevents"), which may hold important additional information on the mechanism of seismogenesis at restless volcanoes. We employ template matching, phase-weighted stacking, and full-waveform inversion to image the source mechanism of one multiplet of these LP subevents at MSH in July 2005. The signal-to-noise ratios of the individual events are too low to produce reliable waveform inversion results, but the events are repetitive and can be stacked. We apply network-based template matching to 8 days of continuous velocity waveform data from 29 June to 7 July 2005 using a master event to detect 822 network triggers. We stack waveforms for 359 high-quality triggers at each station and component, using a combination of linear and phase-weighted stacking to produce clean stacks for use in waveform inversion. The derived source mechanism points to the volumetric oscillation (˜10 m3) of a subhorizontal crack located at shallow depth (˜30 m) in an area to the south of Crater Glacier in the southern portion of the breached MSH crater. A possible excitation mechanism is the sudden condensation of metastable steam from a shallow pressurized hydrothermal system as it encounters cool meteoric water in the outer parts of the edifice, perhaps supplied from snow melt.

    Mount St. Helens has erupted more frequently than any other volcano in the Cascade Range during the past 4,000 years. The volcano has exhibited a variety of eruption styles?explosive eruptions of pumice and ash, slow but continuous extrusions of viscous lava, and eruptions of fluid lava. Evidence of the volcano?s older eruptions is recorded in the rocks that build and the deposits that flank the mountain. Eruptions at Mount St. Helens over the past three decades serve as reminders of the powerful geologic forces that are reshaping the landscape of the Pacific Northwest. On May 18, 1980, a massive landslide and catastrophic explosive eruption tore away 2.7 cubic kilometers of the mountain and opened a gaping, north-facing crater. Lahars flowed more than 120 kilometers downstream, destroying bridges, roads, and buildings. Ash from the eruption fell as far away as western South Dakota. Reconstruction of the volcano began almost immediately. Between 1980 and 1986, 80 million cubic meters of viscous lava extruded episodically onto the crater floor, sometimes accompanied by minor explosions and small lahars. A lava dome grew to a height of 267 meters, taller than the highest buildings in the nearby city of Portland, Oregon. Crater Glacier formed in the deeply shaded niche between the 1980-86 lava dome and the south crater wall. Its tongues of ice flowed around the east and west sides of the dome. Between 1989 and 1991, multiple explosions of steam and ash rocked the volcano, possibly a result of infiltrating rainfall being heated in the still-hot interior of the dome and underlying crater floor. In September 2004, rising magma caused earthquake swarms and deformation of the crater floor and glacier, which indicated that Mount St. Helens might erupt again soon. On October 1, 2004, a steam and ash explosion signaled the beginning of a new phase of eruptive activity at the volcano. On October 11, hot rock reached the surface and began building a new lava dome immediately

    Self-contained, single-frequency GPS instruments fitted on lightweight stations suitable for helicopter-sling payloads became a critical part of volcano monitoring during the September 2004 unrest and subsequent eruption of Mount St. Helens. Known as “spiders” because of their spindly frames, the stations were slung into the crater 29 times from September 2004 to December 2005 when conditions at the volcano were too dangerous for crews to install conventional equipment. Data were transmitted in near-real time to the Cascades Volcano Observatory in Vancouver, Washington. Each fully equipped unit cost about $2,500 in materials and, if not destroyed by natural events, was retrieved and redeployed as needed. The GPS spiders have been used to track the growth and decay of extruding dacite lava (meters per day), thickening and accelerated flow of Crater Glacier (meters per month), and movement of the 1980-86 dome from pressure and relaxation of the newly extruding lava dome (centimeters per day).

    Pyroclastic density currents (PDCs) are one of the most dangerous phenomena associated with explosive volcanism. To help constrain damage potential, a combination of field studies, laboratory experiments, and numerical modeling are used to establish conditions that influence PDC dynamics and depositional processes, including runout distance. The objective of this field trip is to explore field relations that may constrain PDCs at the time of emplacement.The PDC deposits from the May 18, 1980, eruption of Mount St. Helens are well exposed along the steep flanks (10–30° slopes) and across the pumice plain (5–12° slopes) as far as 8 km north of the volcano. The pumice plain deposits represent deposition from a series of concentrated PDCs and are primarily thick (3–12 m), massive, and poorly sorted. In contrast, the steep east-flank deposits are stratified to cross-stratified, suggesting deposition from PDCs where turbulence strongly influenced transport and depositional processes.The PDCs that descended the west flank were largely nondepositional; they maintained a higher flow energy and carrying capacity than PDCs funneled through the main breach, as evidenced by the higher concentration of large blocks in their deposits. The PDC from the west flank collided with PDCs funneled through the breach at various points along the pumice plain. Evidence for flow collision will be explored and debated throughout the field trip.Evidence for substrate erosion and entrainment is found (1) along the steep eastern flank of the volcano, which has a higher degree of rough, irregular topography relative to the west flanks where PDCs were likely nonerosive, (2) where PDCs encountered debris-avalanche hummocks across the pumice plain, and (3) where PDCs eroded and entrained material deposited by PDCs produced during earlier phases of the eruption. Two features interpreted as large-scale (tens of meters wide) levees and a large (~200 m wide) channel scour-and-fill feature

    A devastating pyroclastic surge and resultant lahars at Mount St. Helens on 18 May 1980 produced several catastrophic flowages into tributaries on the northeast volcano flank. The tributaries channeled the flows to Smith Creek valley, which lies within the area devastated by the surge but was unaffected by the great debris avalanche on the north flank. Stratigraphy shows that the pyroclastic surge preceded the lahars; there is no notable "wet" character to the surge deposits. Therefore the lahars must have originated as snowmelt, not as ejected water-saturated debris that segregated from the pyroclastic surge as has been inferred for other flanks of the volcano. In stratigraphic order the Smith Creek valley-floor materials comprise (1) a complex valley-bottom facies of the pyroclastic surge and a related pyroclastic flow, (2) an unusual hummocky diamict caused by complex mixing of lahars with the dry pyroclastic debris, and (3) deposits of secondary pyroclastic flows. These units are capped by silt containing accretionary lapilli, which began falling from a rapidly expanding mushroom-shaped cloud 20 minutes after the eruption's onset. The Smith Creek valley-bottom pyroclastic facies consists of (a) a weakly graded basal bed of fines-poor granular sand, the deposit of a low-concentration lithic pyroclastic surge, and (b) a bed of very poorly sorted pebble to cobble gravel inversely graded near its base, the deposit of a high-concentration lithic pyroclastic flow. The surge apparently segregated while crossing the steep headwater tributaries of Smith Creek; large fragments that settled from the turbulent surge formed a dense pyroclastic flow along the valley floor that lagged behind the front of the overland surge. The unusual hummocky diamict as thick as 15 m contains large lithic clasts supported by a tough, brown muddy sand matrix like that of lahar deposits upvalley. This unit contains irregular friable lenses and pods meters in diameter, blocks incorporated from

    The lateral blast, debris avalanche, and lahars of the May 18th, 1980, eruption of Mount St. Helens, Washington, dramatically altered the surrounding landscape. Lava domes were extruded during the subsequent eruptive periods of 1980–1986 and 2004–2008. More than three decades after the emplacement of the 1980 debris avalanche, high sediment production persists in the Toutle River basin, which drains the northern and western flanks of the volcano. Because this sediment increases the risk of flooding to downstream communities on the Toutle and lower Cowlitz Rivers, the U.S. Army Corps of Engineers (USACE), under the direction of Congress to maintain an authorized level of flood protection, continues to monitor and mitigate excess sediment in North and South Fork Toutle River basins to help reduce this risk and to prevent sediment from clogging the shipping channel of the Columbia River. From October 22–27, 2007, Watershed Sciences, Inc., under contract to USACE, collected high-precision airborne lidar (light detection and ranging) data that cover 273 square kilometers (105 square miles) of lower Cowlitz and Toutle River tributaries from the Columbia River at Kelso, Washington, to upper North Fork Toutle River (below the volcano's edifice), including lower South Fork Toutle River. These data provide a digital dataset of the ground surface, including beneath forest cover. Such remotely sensed data can be used to develop sediment budgets and models of sediment erosion, transport, and deposition. The U.S. Geological Survey (USGS) used these lidar data to develop digital elevation models (DEMs) of the study area. DEMs are fundamental to monitoring natural hazards and studying volcanic landforms, fluvial and glacial geomorphology, and surface geology. Watershed Sciences, Inc., provided files in the LASer (LAS) format containing laser returns that had been filtered, classified, and georeferenced. The USGS produced a hydro-flattened DEM from ground-classified points at

    Recommendations concerning the intake of vitamin D and/or sunlight exposure in the handling of patients with vitamin D deficiency remain a matter of debate. The present study of the German network of dermato-oncologists (Onkoderm e.V.) refers to an inquiry conducted among general practitioners on this and related issues. Based on 448 answers provided to 10 distinct questions, the consulted physicians recommended vitamin D intake (94% replies) and/or exposure to sunlight (63% replies) in their patients with vitamin D deficiency. An average of approximately 26 min daily unprotected exposure to sunlight at midday in spring and summer was recommended. Nevertheless, 91% of the physicians considered the use of creams protecting against sunlight to be judicious. However, only 54% of physicians considered it worthwhile practice to protect oneself intensively against UV radiation. This study indicates evidence of a reduction in sun protection practices. Yet, approximately 25% of the patients were considered to present vitamin D deficiency and, hence, recommendations to prevent or correct the latter situation should not be ignored. Nevertheless, we consider that there is a need to focus messages regarding sun exposure and for continued sun protection practices. These messages should specifically focus on the vitamin D issue to ensure that the incidence of skin cancer does not increase.

  12. Hydrogen isotope investigation of amphibole and glass in dacite magmas erupted in 1980-1986 and 2005 at Mount St. Helens, Washington

    In active, shallow, sub-volcanic magma conduits the extent of the dehydrogenation–oxidation reaction in amphibole phenocrysts is controlled by energetic processes that cause crystal lattice damage or conditions that increase hydrogen diffusivity in magmatic phases. Amphibole phenocrysts separated from dacitic volcanic rocks erupted from 1980 to 1986 and in 2005 at Mount St. Helens (MSH) were analyzed for δD, water content and Fe3+/Fe2+, and fragments of glassy groundmass were analyzed for δD and water content. Changes in amphibole δD values through time are evaluated within the context of carefully observed volcanic eruption behavior and published petrological and geochemical investigations. Driving forces for amphibole dehydrogenation include increase in magma oxygen fugacity, decrease in amphibole hydrogen fugacity, or both. The phenocryst amphibole (δD value c. –57‰ and 2 wt % H2O) in the white fallout pumice of the May 18, 1980 plinian eruptive phase is probably little modified during rapid magma ascent up an ∼7 km conduit. Younger volcanic rocks incorporate some shallowly degassed dacitic magma from earlier pulses, based on amphibole phenocryst populations that exhibit varying degrees of dehydrogenation. Pyroclastic rocks from explosive eruptions in June–October 1980 have elevated abundances of mottled amphibole phenocrysts (peaking in some pyroclastic rocks erupted on July 22, 1980), and extensive amphibole dehydrogenation is linked to crystal damage from vesiculation and pyroclastic fountain collapse that increased effective hydrogen diffusion in amphibole. Multiple amphibole δD populations in many 1980 pyroclastic rocks combined with their groundmass characteristics (e.g. mixed pumice textures) support models of shallow mixing prior to, or during, eruption as new, volatile-rich magma pulses blended with more oxidized, degassed magma. Amphibole dehydrogenation is quenched at the top surface of MSH dacite lava lobes, but the diversity in the

    There is a rich diversity in lava dome morphology, from blocky domes and lobes to imposing spine and whaleback structures. The latter extrude via seismically active, gouge-rich conduit-margin faults, a manifestation of a brittle failure mode. Brittle versus ductile behaviour in volcanic rocks is known to be porosity dependent, and therefore offers a tantalising link between the properties of the material near the conduit margin and the extrusion mechanism (dome or spine). We test this hypothesis by complementing published data on the mechanical behaviour of dacites from the 2004-2008 spine-forming eruption at Mount St. Helens (MSH) with new data on dacite lavas collected from the 1980 dome. The 1980 dacite samples were deformed at room temperature under a range of pressures (i.e., depths) to investigate their mechanical behaviour and failure mode (brittle or ductile). Low-porosity dacite (porosity 0.19) is brittle up to an effective pressure of 30 MPa (depth 1 km) and is ductile at 40 MPa (depth 1.5 km). High-porosity dacite (porosity 0.32) is ductile above an effective pressure of 5 MPa (depth 200 m). Samples deformed in the brittle regime show well-developed ( 1 mm) shear fracture zones comprising broken glass and crystal fragments. Samples deformed in the ductile regime feature anastomosing bands of collapsed pores. The combined dataset is used to explore the influence of strain rate, temperature, and porosity on the mechanical behaviour and failure mode of dacite. A decrease in strain rate does not influence the strength of dacite at low temperature, but reduces strength at high temperature (850 °C). Due to the extremely low glass content of these materials, such weakening is attributed to the increased efficiency of subcritical crack growth at high temperature. However, when strain rate is kept constant, temperature does not significant impact strength reflecting the highly crystallised nature of dacite from MSH. Dacite from the 2004-2008 eruption is stronger

MÉTODOS: Foram entregues questionários para 120 médicos não oncologistas que lidam diretamente com pacientes adultos. RESULTADOS: A taxa de resposta foi de 58,3%. A idade média dos médicos foi de 33,9 anos, sendo 57,1% mulheres e 10% tabagistas. As práticas preventivas para os cânceres mais comuns (mama, colo de útero, próstata, colorretal e pele não-melanoma foram analisadas e comparadas com as recomendadas pelos consensos adotados (INCA, Sociedade Americana de Cancerologia e Força-Tarefa Canadense. Observou-se que a maioria das práticas (45,72% a 100% não se adequou a nenhum deles. Sobre possíveis barreiras para o adequado exercício da prevenção do câncer, 82,86% considerou falta de agentes educadores em saúde para a população, 77,14% poucos conhecimento ou treinamento e 70,15% falta de verba para custear exames. Houve uma tendência ao excesso de pedidos de exames de rastreamento. CONCLUSÕES: As práticas preventivas utilizadas pelos médicos entrevistados são heterogêneas e, em sua maioria, não preconizadas pelos consensos de condutas preventivas consultados, o que pode ser relacionado tanto à sua falta de conhecimento em relação a estes consensos como às divergências entre eles. Dessa forma, faz-se necessário um esforço educativo enfatizando a importância da prevenção do câncer no aprendizado e na prática médica.BACKGOUND: New cancer cases are most often diagnosed by non-oncologist physicians.

    The North Fork Toutle River (NFTR) was severely affected by the 1980 eruption of Mount St.Helens located at Washington State,and its watershed characteristics,water and sediment conditions,channel morphology and boundary conditions have undergone tremendous changes.Its fast and high-magnitude readjustment provided an excellent chance for investigating channel response to extreme disturbances.In this study,we collected geometry data and hydrological data of the last 30 years for 14 cross sections in the upper and middle reaches of this river and comprehensively analyzed the vertical,lateral and longitudinal variations of channel geometry.The results show that the river adjusted most rapidly during the first three years after the eruption,but the adjustment rate decayed with time and the channel gradually tended to a stable or equilibrium state,reflecting the auto-conditioning of natural fluvial system.The channel bed was severely degraded in the upper reach while aggraded in the lower reach,which jointly decreased the slope of channel bed and lowered the stream power.This was the way that the river conditioned itself and relaxed to a relatively stable state.Bank collapse was another significant aspect of channel response to the eruption and all the cross sections in the studied reach experienced bank erosion in different degrees.Bank collapse in the head reach and the narrow channel reaches was induced by consistent channel bed erosion while that in the wide channel reaches downstream was caused by lateral shift of main channel.%受1980年美国华盛顿州圣海伦斯火山爆发的影响,图特河北汊的流域特性、水沙条件和河床边界条件均发生了巨大变化,河流的调整和响应十分迅速,为研究河流受突发剧烈扰动后的河床再调整过程提供了一个很好的范例.本文选取图特河北汉上中游14个测量断面为研究对象,收集了近30年来的水文泥沙和断面资料,对河道的垂向、横向及纵向的

    We compare eruptive dynamics, effects and deposits of the Bezymianny 1956 (BZ), Mount St Helens 1980 (MSH), and Soufrière Hills volcano, Montserrat 1997 (SHV) eruptions, the key events of which included powerful directed blasts. Each blast subsequently generated a high-energy stratified pyroclastic density current (PDC) with a high speed at onset. The blasts were triggered by rapid unloading of an extruding or intruding shallow magma body (lava dome and/or cryptodome) of andesitic or dacitic composition. The unloading was caused by sector failures of the volcanic edifices, with respective volumes for BZ, MSH, and SHV c. 0.5, 2.5, and 0.05 km3 . The blasts devastated approximately elliptical areas, axial directions of which coincided with the directions of sector failures. We separate the transient directed blast phenomenon into three main parts, the burst phase, the collapse phase, and the PDC phase. In the burst phase the pressurized mixture is driven by initial kinetic energy and expands rapidly into the atmosphere, with much of the expansion having an initially lateral component. The erupted material fails to mix with sufficient air to form a buoyant column, but in the collapse phase, falls beyond the source as an inclined fountain, and thereafter generates a PDC moving parallel to the ground surface. It is possible for the burst phase to comprise an overpressured jet, which requires injection of momentum from an orifice; however some exploding sources may have different geometry and a jet is not necessarily formed. A major unresolved question is whether the preponderance of strong damage observed in the volcanic blasts should be attributed to shock waves within an overpressured jet, or alternatively to dynamic pressures and shocks within the energetic collapse and PDC phases. Internal shock structures related to unsteady flow and compressibility effects can occur in each phase. We withhold judgment about published shock models as a primary explanation for the

  1. Pancreatic Cancer: What the Oncologist Can Offer for Palliation

    Directory of Open Access Journals (Sweden)

    Malcolm J Moore

    2002-01-01

    Full Text Available Because pancreatic cancer has a poor survival rate and only 20% of patients present with potentially resectable disease, a key goal of therapy is to provide palliation. The poor medical condition of many patients interferes with their ability to tolerate traditional chemotherapy. Recently, however, a nucleoside analogue, gemcitabine, has been developed. This drug is more effective than 5-fluorouracil (5-FU, can be used in patients who fail to respond to 5-FU and has only modest toxicity. Combination therapies including gemcitabine and other agents are being tested. Local radiotherapy seems to provide pain relief, but gastrointestinal toxicity is significant. The effect of combined modality therapy (5-FU with radiotherapy on survival is unclear, and it does not prevent local disease progression. Some novel biological agents, including angiogenesis inhibitors, matrix metalloproteinase inhibitors, antisense compounds, inhibitors of cell signalling such as epidermal growth factor and vascular endothelial growth factor, and inhibitors of oncogene activation, are undergoing phase II and III trials in patients with pancreatic cancer. Among the most promising are farnesyl protein transferase inhibitors, which modulate K-ras function. Such an approach is promising for the treatment of pancreatic cancer because this tumour frequently exhibits mutation of the ras gene.

    Many biologic products have improved the outcomes of cancer patients, but the costs can substantially burden healthcare systems. Biosimilar products can potentially reduce drug costs and increase patient access to beneficial treatments. Approval of a biosimilar product relies on the demonstration of “comparability” or “no clinically meaningful differences” as compared to its reference biologic product.

  10. What Medical, Urologic, and Radiation Oncologists Want from Molecular Imaging of Prostate Cancer.

    Science.gov (United States)

    Ballas, Leslie K; de Castro Abreu, Andre Luis; Quinn, David I

    2016-10-01

    As molecular imaging better delineates the state of prostate cancer, clinical management will evolve. The currently licensed imaging modalities are limited by lack of specificity or sensitivity for the extent of cancer and for predicting outcome in response to therapy. Clinicians want molecular imaging that-by being more reliable in tailoring treatment and monitoring response for each patient-will become a key facet of precision medicine, surgery, and radiation therapy. Identifying patients who are candidates for specific or novel treatments is important, but equally important is the finding that a given patient may not be a good candidate for single-modality therapy. This article presents prostate cancer scenarios in which managing clinicians would welcome molecular imaging innovations to help with decision making. The potential role of newer techniques that may help fill this wish list is discussed. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

    Lung cancer is the leading cause of cancer-related death around the world; the addition of chemotherapy to treatment of this disease has been shown to significantly increase progression-free survival and overall survival. Despite newer chemotherapies, it is important to personalize the care (treatment and dose) upon each single patient's susceptibility for controlling and reducing adverse side-effects, at best. The present review describes the current status of pharmacogenomics studies regarding germline DNA variants that may alter response and tolerability to chemotherapeutic agents used to treat lung cancer, including perspective studies.

We undertook this study to identify how frequently final tumor stage and treatment recommendations changed from diagnostic biopsy to final histopathology after wide local excision (WLE. Methods. We compared the histopathology of the dermatopathologist-reviewed diagnostic biopsy and final WLE in 332 cutaneous melanoma patients. Results. Tumor sites were extremity (51%, trunk (33%, and head/neck (16%. Initial biopsy types were excisional (56%, punch (21%, shave (18%, and incisional (5%. Most diagnostic biopsies were margin positive regardless of technique, and 36% of patients had residual melanoma on WLE. T-stage changed in 8% of patients, of whom 59% were diagnosed by punch biopsy, 15% by incisional biopsy, 15% by shave biopsy, and 11% by excisional biopsy (P<0.0001. Treatment recommendations changed in 6%: 2% after excisional biopsy, 5% after shave biopsy, 18% after punch biopsy, and 18% after incisional biopsy (P<0.0001. Conclusions. Although most biopsy margins were positive, T-stage and treatment changed for only a minority of melanoma patients. Our data provide valuable information to inform patient discussion regarding the likelihood of a change in prognosis and the need for secondary procedures after WLE. These data support the superiority of dermatopathologist-reviewed excisional biopsy when feasible.

    Counterfeit pharmaceuticals pose risks domestically. Because of their cost, cancer pharmaceuticals are vulnerable. We review findings from a domestic counterfeiting episode involving erythropoietin and outline anticounterfeiting recommendations for policy makers, patients, and health care professionals. Information was obtained on patients who received counterfeit erythropoietin, its distribution, and criminal investigations into counterfeiting networks. Interview sources included a physician, an attorney, employees of the Florida Department of Health and Human Services and the US Food and Drug Administration's (FDA) Office of Criminal Investigation, manufacturers, and wholesalers. Other sources included the book "Dangerous Doses," LexisNexis (search terms "counterfeit" and "erythropoietin") and the FDA database. Counterfeit product consisted of 2,000 U vials with counterfeit labels denoting 40,000 U. The counterfeiters, in collaboration with a Miami pharmacy, purchased 110,000 erythropoietin 2,000 U vials and affixed counterfeit labels to each vial. Products were then sold via the pharmaceutical "gray market" to wholesalers, then pharmacy chains. Investigations by Florida government officials implicated 17 persons, all of whom were found guilty of trafficking in counterfeit pharmaceuticals. Despite the large size of the operation, the FDA received reports of only 12 patients who had received counterfeit erythropoietin and detailed information for only two individuals. A 17-year-old liver transplant recipient and a 61-year-old patient with breast cancer experienced loss of efficacy after receiving counterfeit erythropoietin. Wider use of FDA anticounterfeit initiatives, limiting pharmaceutical suppliers to reputable distributors, and educating providers and patients about signs of counterfeit drugs can improve the safety of cancer pharmaceuticals.

    Epidemiologic studies show that malnutrition frequently afflicts elderly cancer patients. Malnutrition, (expressed as weight loss, or depletion of some body compartments or alteration of nutritional clinical or biochemical scores) is associated with higher morbidity/mortality, poor quality of life, reduced tolerance to oncologic therapy and poor efficacy of chemotherapy. Recently, sarcopenia, regardless of the presence of weight loss, has been identified as an independent risk factor for chemotherapy toxicity. Copyright © 2015 Elsevier Inc. All rights reserved.

    Members of the Society of Gynecologic Oncology (SGO were surveyed electronically regarding consistency of counseling patterns of contraception and fertility concerns, most and least common contraceptive methods utilized, referral patterns, and incidence of unplanned pregnancy. Of the 1424 SGO members identified, 261 participated in the questionnaire, yielding a response rate of 18%. Eighty-two percent of respondents agreed unplanned pregnancy is a potential problem, but only 57% believed their patients understood unplanned pregnancy is possible during treatment. Half of respondents report “always” in terms of frequency that contraception is addressed among their high-risk patients. After adjustment for gender, we found that the odds of reporting providing fertility counseling were nearly three times higher among attendings as compared to fellows [AOR = 2.72; 95% CI = (1.44, 5.12, three times higher in women as compared to men [AOR = 2.80; 95% CI = (1.46, 5.38], as well as in individuals 50+ years as compared to those <40 years old [AOR = 4.91; 95% CI = (2.05, 11.74]. Ninety-six percent reported <5 unplanned pregnancies, to their knowledge, in the previous five years of clinical practice. Most providers acknowledge that unplanned pregnancy is a potential risk in fertile gynecologic oncology patients, but only half believe their patients understand an unplanned pregnancy is possible. An opportunity exists to provide more directed counseling regarding fertility during and after cancer therapy, and to educate patients and providers regarding more reliable, long acting contraceptive methods.

    Fibrous dysplasia (FD) is categorized as either monostotic or polyostotic and may occur as a component of McCune-Albright syndrome (MAS). Imaging findings can mimic neoplastic diseases. We present a case of MAS initially suspected to have neoplastic disease. A 9-year-old girl was admitted to pediatric emergency with ataxia. Upon hospitalization, an extradural mass was seen on cranial magnetic resonance imaging (MRI) and the bone survey showed lytic lesions in the long bones. The patient was referred to the pediatric oncology department with a presumptive diagnosis of Langerhans cell histiocytosis or metastatic tumor. Further investigations demonstrated that the patient had MAS and coexisting postinfectious cerebellitis. The findings in this patient demonstrate that the radiographic findings and the clinical presentation of FD and MAS may be similar to those of malignant diseases.

    2016-07-01

    To our knowledge this is the first systemic review that provides an overview of the cutaneous paraneoplastic syndromes (CPS) (i.e., clinical manifestations, pathomechanisms, and treatment modalities) occurring in stomach cancer. CPS are caused by substances produced by stomach cancer and may precede, coincide with, or follow the diagnosis of this malignancy. More than 20 possible CPS in association with stomach cancer have been identified. CPS mostly compromises the patient's quality of life by skin impairment plus discomfort and are often associated with a dismal prognosis on survival. Studies of these CPS not only in stomach cancer have partially contributed to the understanding of pathomechanism and since CPS may be the presenting sign of an occult cancer, cognizance of their features and clinical implications are of considerable importance. Patients with these syndromes should have an appropriate work-up for a possibly occult malignancy with consecutive successful early treatment.

    The basic principle of palliative care has evolved over time and is the historical origin of the modern hospice. WHO proposed the first definition of palliative care in 1989, and the definition was revised in 2002. These definitions have something in common. Both relieve the pain and suffering to improve QOL. Palliative care is also good for any kind of life-threatening disease, regardless of whether it requires short or long term recuperation. That also need to be able to accept equally all the people of the community. The provision of general palliative care is the responsibility of all medical, nursing, and health professionals for the welfare of all patients with life-threatening disease. Specialist palliative care is based on the basic principles of palliative care, intensive clinical training, and systematic acquisition of knowledge and skills training to support palliative care education, clinical research and training provided by the profession. It has been established by nursing and medical experts in palliative care that palliative care can provide expertise in interdisciplinary teams in different settings. It is necessary that the medical system.

The objective of this analysis is to demonstrate the impact of the radiation oncology didactic on medical student knowledge of core oncology concepts. All students received a standardized didactic lecture introducing students to core concepts of general oncology and radiation. We administered an 18-question pretest and a posttest examining student knowledge between 2012 and 2015. Changes in student responses between pre-test and post-tests were analyzed to evaluate the effectiveness of the didactic session. Over the course of three years, 319 (64.4%) of 495 students who completed the Radiology block completed both the pre-test and post-test.

    This study aims to assess the efficacy of a radiation therapy (RT) education video for patients referred for treatment. The investigators produced a 23-min guide to radiation therapy DVD, combining didactic material and patient narratives. Patients (n=32) had not yet received their initial consultation. Baseline awareness about cancer and treatment was assessed by surveys including the rapid estimate of adult literacy in medicine. Knowledge about RT was assessed before and after viewing the video with a separate 21 question survey. Differences in benefit for sociodemographic subgroups including age, gender, ethnicity, income, education, and health literacy level were explored. Baseline assessments identified 78 % of patients regardless of sociodemographic status had "little" to "no" basic knowledge of RT. The mean number of correct responses in the 21 question survey assessing how RT works improved from 9.8 to 11.1 after watching the video (peducation (p=0.002). Patient satisfaction with the video was high. Knowledge among cancer patients regarding RT is poor, regardless of sociodemographic factors. This pilot study demonstrates the utility of a brief video to universally improve patient awareness about RT. While patients may ultimately learn about RT during their course of treatment, we advocate for any tools that can improve patient knowledge at the time of initial consultation as this is typically the time they are asked to acknowledge informed consent for treatment.

    Full Text Available Introduction. Hydatid disease is a cyclozoonotic parasitic infestation caused by the cestode Echinococcus granulosus. The cysts mainly arise in the liver (50 to 70% or lung (20 to 30%, but any other organ can be involved, in abdominal and pelvic locations, as well as in other less common sites, which may make both diagnosis and treatment more complex. Isolated renal involvement is extremely rare. Case Presentation. We report a rare case of isolated renal hydatid disease in a 71-year-old man with a history of vague abdominal pain, anemia, fever, and microhematuria. Ultrasonographic examination revealed a complex cyst in the right kidney, including multiple smaller cysts with internal echoes. A magnetic resonance scan of the abdomen confirmed the findings, and hydatid cyst disease was diagnosed. Right nephrectomy was performed, and microscopic examination confirmed the diagnosis of hydatid cyst. Albendazole, 10 mg/kg per day, was given for 4 weeks (2 weeks preoperatively and 2 weeks postoperatively. Conclusion. Isolated primary hydatidosis of the kidney should always be considered in the differential diagnosis of any cystic renal mass, even in the absence of accompanying involvement of liver or other visceral organs.

    2004-12-01

    For 26 years (1971-1997), the University of Toronto operated a very productive 60-cm optical telescope on Carnegie's Cerro Las Campanas in north-central Chile. Due to a series of cutbacks in subsidies through NSERC, Canada's research-funding agency, the doors were closed on 01 July 1997 (Canada Day). Following an agreement between astronomers at DDO (Canada) and CASLEO, Argentina, the telescope and dome were relocated on Cerro Burek in Parque Nacional El Leoncita, Argentina, just on the other side of the Andes from Ovalle, Chile. The new building is 3 meters higher and has a dozen ventilating windows. The result is unexpectedly superior seeing. The average point spread function is 0.7 arcseconds. During construction of the building and rebuilding of the telescope, all decisions were made with the intention of operating the telescope remotely, initially from the warmroom of the CASLEO 2.15 meter telescope and ultimately from Toronto and San Juan.

    A 6.6 ha grassland, established on a former chemical waste site adjacent to a residential area, contains arsenic (As) in surface soil at concentrations 200 times higher than UK Soil Guideline Values. The site is not recognized as statutory contaminated land, partly on the assumption that mobility of the metalloid presents a negligible threat to human health, groundwater and ecological receptors. Evidence for this is evaluated, based on studies of the effect of organic (green waste compost) and inorganic (iron oxides, lime and phosphate) amendments on As fractionation, mobility, plant uptake and earthworm communities. Arsenic mobility in soil was low but significantly related to dissolved organic matter and phosphate, with immobilization associated with iron oxides. Plant uptake was low and there was little apparent impact on earthworms. The existing vegetation cover reduces re-entrainment of dust-blown particulates and pathways of As exposure via this route. Minimizing risks to receptors requires avoidance of soil exposure, and no compost or phosphate application. - Stabilization of alkali industry waste requires careful management to minimise soil arsenic mobilization and dispersal to the wider environment.

    Full Text Available En su Helena, Eurípides teoriza las dificultades de la onomástica: los nombres recubren la identidad de múltiples homónimos o bien un nombre designa muchas esencias de un mismo individuo, como ocurre con la verdadera reina de Esparta y su eídolo. Estas observaciones adquieren una significación teatral, pues un personaje como Teucro, mal integrado en la acción si se tratara del famoso arquero homérico, se insertaría en un rol muy pertinente si se reconociera en él al meteco que denuncia la parodia de los misterios de Eleusis por Alcibíades. Además, cierta tradición crítica ha distinguido trazos del joven estratega bajo la puesta en escena de la protagonista. La obra de Eurípides sugiere, de hecho, de manera esotérica, el progreso escénico de una rehabilitación y de una iniciación no solo de Helena (sobre el plano de la representación mitológica, sino también de Alcibíades (sobre el plano político. Por otra parte, el nombre y la función dramática de Teónoe están realmente demasiado cercanos a aquellos de Téano (la sacerdotisa de Eleusis citada por Plutarco como la única en haberse negado a maldecir a Alcibíades, como para que la similitud onomástica sea fortuita

    Authors suggest to read carefully the text written by Louis Althusser concerning the murder of his wife, Hélène. In place of hypothetical psychopathological elaborations they propose to take into account the narration of his personal story, and his illness leading to a delusional and confusional depression. The precision in the written report by Althusser on his painful manic depression demonstrates that there is no place for hypothesis too different from an ordinary reality.

    Ambulatory oncology nurses struggle to meet the increasing demands placed on them. Increased volume of patients, more complex treatments and symptom management, an older population with multiple co-morbidities combined with fiscal and human resource restraints has created job dissatisfaction and the feeling of powerlessness in the current environment. The Appreciative Inquiry process enables nurses to become engaged in planning and creating positive change based on their knowledge, experiences and clinical expertise, as oncology professionals. Through surveys and group work, nurses in this project were able to turn theory into positive practice change, inspiring a new paradigm of primary oncology nursing. Through the promotion of innovation, we have inspired hope while advocating for our profession.

    Full Text Available This article analyses the three epideictic orations of Isocrates which are in themselves a precious testimony of the quality of intellectual life at the close of the fourth century before Christ. To this period belong also the Socratics who are generally seen as an important link between Socrates and Plato. The author of this article proposes a more productive approach to the study of Antisthenes, Euclid of Megara and other so-called Socratics, revealing them not as independent thinkers but rather as adherents of the sophistic school and also as teachers, thereby, including them among those who took part in the educative activity of their time

  7. A clinical review of communication training for haematologists and haemato-oncologists: a case of art versus science.

    Science.gov (United States)

    Christie, Deborah; Glew, Sarah

    2017-07-01

    The art of communication at times seems at odds with the science of medicine. Poor communication is associated with risks for patient and physician. Communication skills are highly relevant for haematologists and are associated with increased physician and patient satisfaction, positive psychosocial outcomes and possible health outcomes. Medical communication training has recently become widespread but is largely restricted to junior medical professionals. In haematology, the proliferation of high quality communication skills is low and there are few interventions catering for the required skillset. A review identified five applicable interventions for haematologists. There is variation in intervention length and structure, and most studies measure targeted skill fidelity rather than patient outcomes. Work on motivation and empowerment holds potential for haematological conditions, but is largely absent from care. This review highlights the need for new interventions for haematologists which focus on producing and maintaining positive patient outcomes. © 2017 John Wiley & Sons Ltd.

  8. Communication behaviours of skilled and less skilled oncologists: a validation study of the Medical Interaction Process System (MIPS).

    Science.gov (United States)

    Ford, Sarah; Hall, Angela

    2004-09-01

    The Medical Interaction Process System (MIPS) was originally developed in order to create a reliable observation tool for analysing doctor-patient encounters in the oncology setting. This paper reports a series of analyses carried out to establish whether the behaviour categories of the MIPS can discriminate between skilled and less skilled communicators. This involved the use of MIPS coded cancer consultations to compare the MIPS indices of 10 clinicians evaluated by an independent professional as skilled communicators with 10 who were considered less skilled. Eleven out of the 15 MIPS variables tested were able to distinguish the skilled from the less skilled group. Although limitations to the study are discussed, the results indicate that the MIPS has satisfactory discriminatory power and the results provide validity data that meet key objectives for developing the system. There is an ever-increasing need for reliable methods of assessing doctors' communication skills and evaluating medical interview teaching programmes.

    Several key medical and oncologic professional societies have endorsed the importance of physician communication as a quality improvement metric. Despite this clear message, there remain substantial barriers to communication skills training (CST) in oncologic specialties. Herein, we describe the major barriers to communications training and propose standardized patient (SP) programs as efficient and strategic starting points and as expansion opportunities for new and existing CSTs.

    Cannone, Patrice; Dany, Lionel; Dudoit, Eric; Duffaud, Florence; Salas, Sébastien; Favre, Roger

    2004-03-01

    This research aims to study social representations throughout chemiotherapy, out of a population composed of doctors specialized in Oncology on one hand, and patients dealing with cancer during their chemiotherapy on the other hand. Our methodology is situated among quantitative methods using SPSS for Anovas to analyze statistics datas, EVOQ and Alceste for the pragmatic analysis of the discourse. The datas were collected from a questionnaire including items and words associations. We were interested in chemiotherapy which appears as a social object likely to generate a representative process from which emerges a serie of adaptative strategies belonging to both cognitivo-behaviourism and emotional spheres. chemiotherapy leads to an adaptation of the patient and remains a mediator in the doctor-patient's relation. As far as representations are "action guides", the existence of a representation specific to patients and doctors, allowes us to point out, through a semantic and emotional gap a technical medicine which is, in the future, likely to tend to existentialism.

    To assess the effect of neoadjuvant chemotherapy (NACT) on breast cancer characteristics, hormone receptors and human epidermal growth factor receptor 2 (HER2) expression and whether testing should be repeated on residual tumours. Patients with primary operable breast cancer who received NACT at a single United Kingdom tertiary referral centre were included. Tumour type, grade (including details of mitotic grade, tubule formation and pleomorphism), oestrogen receptor (ER), progesterone receptor (PR) and HER2 status were compared between pre-treatment and post-treatment residual samples using tissue microarrays. A control group of paired core and excision tumours from patients who did not receive NACT was also assessed. Two hundred forty-six cases and 113 controls were included. Pathological complete response (path CR) was achieved in 21.5% of patients. In those patients failing to achieve a path CR, a change in the histological type was noted in 29 out of 178 cases (16.3%, pnegative to positive status for ER and from positive to negative status for HER2. Further alterations in expression levels were also noted. Minimal changes in the low ER/PR expressors and the HER2 2+ tumours were found in the control group. Significant changes in tumour morphology, grade, hormone receptors and HER2 status occur following NACT. We recommend testing on residual invasive carcinoma. A switch from negative to positive status warrants offering endocrine/trastuzumab-based therapy to this group of patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

In a control group (n = 56 only a traditional thyroid scan method of primary diagnostics was used which doesn’t give enough data for planning of extent of an operation. In a comparison set (n = 82 a protocol of preoperative thyroid and regional efflux of lymph examination was introduced. Within the protocol in addition to the traditional thyroid scan method an authors’ improved method of a repeated (duplicate neck scan and a new method of ultrasonic cervical glands assessment were used which led to significant improvement of the preoperative thyroid cancer diagnostics: agreement climb in preoperative and postoperative diagnoses of 36.10 per cent, climb in preoperatively diagnosed extrathyroidal invasion of 34.15 per cent, climb in preoperatively diagnosed tumor recurrence of 15.85 per cent, climb in tumor cervical glands disease diagnostics of 34.80 per cent.

    Between January 1994 and December 2004, 696 patients with localized endometrial carcinoma have been treated at the Institute Jean-Godinot. Patients were selected on the following criteria: histologically proven adenocarcinoma of the endometrium; age at onset under 60 years; patient not deceased at the time of the study. One hundred twelve patients met these criteria and received a mailed specific questionnaire to establish their pedigree. Thirty-one patients (35.5%) were eventually found eligible for a genetic counselling but only 13 patients agreed to be informed later on. According to the obtained pedigrees and MSI test results, 7 genetic tests have been carried out and so far, 3 MMR mutations were detected. This study suggested the feasibility of a step by step screening of endometrial cancers to select patients at risk for Lynch syndrome and for whom a genetic test would be recommended. Authors suggest that either Amsterdam or Bethesda criteria should be systematically used prospectively in every newly diagnosed endometrial cancer and retrospectively using clinical databases available on endometrial cancers.

    Numerical simulations, using the weather research and forecasting (WRF) model in concert with GPS dropwindsondes released during the NASA African Monsoon Multidisciplinary Analyses 2006 Field Campaign, were conducted to provide additional insight on SAL-TC interaction. Using NCEP Final analysis datasets to initialize the WRF, a sensitivity test was performed on the assimilated (i.e., observation nudging) GPS dropwindsondes to understand the effects of individual variables (i.e., moisture, temperature, and winds) on the simulation and determine the extent of improvement when compared to available observations. The results suggested that GPS dropwindsonde temperature data provided the most significant difference in the simulated storm organization, storm strength, and synoptic environment, but all of the variables assimilated at the same time give a more representative mesoscale and synoptic picture.
