Administration of Blood By Registered Nurses—Joint Statement by California Medical Association,California Hospital Association and California Nurses' Association

After several years of favorable experience with registered nurses giving intravenous injections of fluids under the criteria set out in a joint statement by the California Medical Association, the California Hospital Association and the California Nurses'' Association,^* it was proposed that it would be appropriate for registered nurses to administer blood. Careful study of current experience in various places with registered nurses giving blood transfusions convinced a joint committee that it recommend the adoption of the following statement which was approved by the associations indicated.

This joint statement was approved by the Canadian Healthcare Association, the CMA, the Canadian Nurses Association and the Catholic Health Association of Canada and was developed in cooperation with the Canadian Bar Association.     

Did Osler suffer from "paranoia antitherapeuticum baltimorensis"?: A comparative content analysis of The Principles and Practice of Medicine and Harrison's Principles of Internal Medicine, 11th edition

One of the most important legacies of Sir William Osler was his textbook The Principles and Practice of Medicine. A common criticism of the book when it was first published was its deficiency in the area of therapeutics. In this article, the 1st edition of The Principles and Practice of Medicine is compared with the 11th edition of Harrison''s Principles of Internal Medicine. The analysis focuses on the treatment recommendations for 4 conditions that were covered in both books (diabetes mellitus, ischemic heart disease, pneumonia and typhoid fever). Osler''s textbook dealt with typhoid fever and pneumonia at greater length, whereas Harrison''s placed more emphasis on diabetes mellitus and ischemic heart disease. Notwithstanding Osler''s reputation as a therapeutic nihilist, the 2 books devoted equivalent space to treatment (in terms of proportion of total sentences for the conditions). For all conditions except ischemic heart disease, Osler concentrated on general measures and symptomatic care. Throughout Osler''s textbook numerous negative comments are made about the medicinal treatment of various conditions. A more accurate statement about Osler''s therapeutic approach was that he was a "medicinal nihilist." His demand for proof of efficacy before use of a medication remains relevant.     

The vexed question of authorship: views of researchers in a British medical faculty.

OBJECTIVE: To assess knowledge, views, and behaviour of researchers on criteria for authorship and causes and control of gift authorship. DESIGN: Interview survey of stratified sample of researchers. SETTING: University medical faculty. SUBJECTS: 66 staff (94% response rate) comprising several levels of university academic and research appointments. MAIN OUTCOME MEASURES: Awareness and use of criteria for authorship, views on which contributions to research merit authorship, perceptions about gift authorship and strategies for reducing it, and experiences of authorship problems. RESULTS: 50 (76%) respondents supported criteria for authorship, but few knew about or used available criteria. Of the five people who could specify all three criteria of the International Committee of Medical Journal Editors, only one knew that all criteria had to be met. Forty one respondents (62%) disagreed with this stipulation. A range of practical and academic contributions were seen as sufficient for authorship. Gift authorship was perceived as common, promoted by pressure to publish, to motivate research teams, and to maintain working relationships. A signed statement justifying authorship and a published statement of the contribution of each author were perceived as practical ways of tackling gift authorship. Most researchers had experienced problems with authorship, most commonly the perception that authorship had been deserved but not awarded (49%). CONCLUSION: There seems to be a gap between editors'' criteria for authorship and researchers'' practice. Lack of awareness of criteria is only a partial explanation. Researchers give more weight than editors to practical research contributions. Future criteria should be agreed by researchers and not be imposed by editors.     

Darwin's error? Patrick Matthew and the catastrophic nature of the geologic record

In 1831, the Scottish horticulturalist Patrick Matthew (1790–1874) published a clear statement of the law of natural selection in an Appendix to his book Naval Timber and Arboriculture, which both Darwin and Wallace later acknowledged. Matthew, however, was a catastrophist, and he presented natural selection within the contemporary view that relatively long intervals of environmental stability were episodically punctuated by catastrophic mass extinctions of life. Modern studies support a similar picture of the division of geologic time into long periods of relative evolutionary stability ended by sudden extinction events. Mass extinctions are followed by recovery intervals during which surviving taxa radiate into vacated niches. This modern punctuated view of evolution and speciation is much more in line with Matthew's episodic catastrophism than the classical Lyellian–Darwinian gradualist view.     

Consistency of financial interest disclosures in the biomedical literature: the case of coronary stents

Background

Disclosure of authors'' financial interests has been proposed as a strategy for protecting the integrity of the biomedical literature. We examined whether authors'' financial interests were disclosed consistently in articles on coronary stents published in 2006.

Methodology/Principal Findings

We searched PubMed for English-language articles published in 2006 that provided evidence or guidance regarding the use of coronary artery stents. We recorded article characteristics, including information about authors'' financial disclosures. The main outcome measures were the prevalence, nature, and consistency of financial disclosures. There were 746 articles, 2985 authors, and 135 journals in the database. Eighty-three percent of the articles did not contain disclosure statements for any author (including declarations of no interests). Only 6% of authors had an article with a disclosure statement. In comparisons between articles by the same author, the types of disagreement were as follows: no disclosure statements vs declarations of no interests (64%); specific disclosures vs no disclosure statements (34%); and specific disclosures vs declarations of no interests (2%). Among the 75 authors who disclosed at least 1 relationship with an organization, there were 2 cases (3%) in which the organization was disclosed in every article the author wrote.

Conclusions/Significance

In the rare instances when financial interests were disclosed, they were not disclosed consistently, suggesting that there are problems with transparency in an area of the literature that has important implications for patient care. Our findings suggest that the inconsistencies we observed are due to both the policies of journals and the behavior of some authors.     

A 2013 linear sequence of legume genera set in a phylogenetic context — A tool for collections management and taxon sampling

The Leguminosae (or Fabaceae) currently comprises 751 genera. In most of the world's herbaria the genera are arranged by old, non-phylogenetic, classification systems which, while offering insights into morphological similarity, make no explicit statement as to evolutionary relationships. While classifications based on morphology are useful tools for plant identification, they do not offer the predictive value that phylogenetically based linear sequences provide. The legume collection of c.750,000 specimens in the Herbarium of the Royal Botanic Gardens, Kew was moved to a new building between 2010 and 2011, which presented the opportunity to reorganise the collection by a linear sequence based on a number of relatively comprehensive published legume phylogenies. The numbered linear sequence adopted at Kew has been updated and emended to include generic changes that have been published up to March 2013. The linear sequence, together with an alphabetical list of genera, is presented here to serve as a management tool for future taxon sampling and herbarium curation. The process used to develop the linear sequence and to rearrange the legume collection at Kew is discussed together with plans for future dissemination of changes to the sequence as new phylogenies are published and incorporated.     

Subject-specific bone remodelling of the scapula

Finite element analyses, with increasing levels of detail and complexity, are becoming effective tools to evaluate the performance of joint replacement prostheses and to predict the behaviour of bone. As a first step towards the study of the complications of shoulder arthroplasty, the aim of this work was the development and validation of a 3D finite element model of an intact scapula for the prediction of the bone remodelling process based on a previously published model that attempts to follow Wolff's law. The boundary conditions applied include full muscle and joint loads taken from a multibody system of the upper limb based on the same subject whose scapula was here analysed. To validate the bone remodelling simulations, qualitative and quantitative comparisons between the predicted and the specimen's bone density distribution were performed. The results showed that the bone remodelling model was able to successfully reproduce the actual bone density distribution of the analysed scapula.

An instrument for assessment of videotapes of general practitioners' performance.

OBJECTIVES--To identify those important characteristics of doctors'' and patients'' behaviour that distinguish between "good" and "bad" consultations when viewed on videotape; to use these characteristics to develop a reliable instrument for assessing general practitioners'' performance in their own consultations. DESIGN--Questionnaires completed by patients, general practitioner trainers, and general practitioner trainees. Reliability of draft instrument tested by general practitioner trainers. SETTING--All vocational training schemes for general practice in the Northern region of England. SUBJECTS--First stage: 76 patients in seven groups, 108 general practice trainers in 12 groups, and 122 general practice trainees in 10 groups. Second stage: 85 general practice trainers in 12 groups. MAIN OUTCOME MEASURES--Trainers'' ratings of importance; alpha coefficients of draft instrument by trainee, group, and consultation. RESULTS--6890 characteristics of good and bad consultations were consolidated into a draft assessment instrument consisting of 46 pairs of definitions separated by six point bipolar scales. Nine statement pairs given low importance ratings by trainers were eliminated, reducing the instrument to 37 statement pairs. To test reliability, general practitioner trainers used the instrument to assess three consultations. With the exception of one group of trainers, all alpha coefficients exceeded the acceptable level of 0.80. CONCLUSION--The instrument produced is reliable for assessing general practitioners'' performance in their own consultations.

Points to Consider: Ethical,Legal, and Psychosocial Implications of Genetic Testing in Children and Adolescents

In 1995, the American Society of Human Genetics (ASHG) and American College of Medical Genetics and Genomics (ACMG) jointly published a statement on genetic testing in children and adolescents. In the past 20 years, much has changed in the field of genetics, including the development of powerful new technologies, new data from genetic research on children and adolescents, and substantial clinical experience. This statement represents current opinion by the ASHG on the ethical, legal, and social issues concerning genetic testing in children. These recommendations are relevant to families, clinicians, and investigators. After a brief review of the 1995 statement and major changes in genetic technologies in recent years, this statement offers points to consider on a broad range of test technologies and their applications in clinical medicine and research. Recommendations are also made for record and communication issues in this domain and for professional education.     

The significance of Aleš Hrdlička's “Neanderthal phase of man”: A historical and current assessment

Ale? Hrdli?ka's hypothesis on a Neandertal phase of human evolution is examined in light of current data and interpretations on Neandertals. Hrdli?ka's interpretations are related to his ideas regarding the peopling of the New World. A major early statement of Hrdli?ka's views on Neandertal was his Huxley Memorial Lecture of 1927. We assess this formulation and subsequent development of his hypothesis. Hrdli?ka's position is compared with the “presapiens” and “pre-neandertal” hypotheses on the basis of current theory and data.     

Estimation of foot joint kinetics in three and four segment foot models using an existing proportionality scheme: Application in paediatric barefoot walking

Recent studies which estimated foot segment kinetic patterns were found to have inconclusive data on one hand, and did not dissociate the kinetics of the chopart and lisfranc joint. The current study aimed therefore at reproducing independent, recently published three-segment foot kinetic data (Study 1) and in a second stage expand the estimation towards a four-segment model (Study 2).Concerning the reproducibility study, two recently published three segment foot models (Bruening et al., 2014; Saraswat et al., 2014) were reproduced and kinetic parameters were incorporated in order to calculate joint moments and powers of paediatric cohorts during gait. Ground reaction forces were measured with an integrated force/pressure plate measurement set-up and a recently published proportionality scheme was applied to determine subarea total ground reaction forces. Regarding Study 2, moments and powers were estimated with respect to the Instituto Ortopedico Rizzoli four-segment model. The proportionality scheme was expanded in this study and the impact of joint centre location on kinetic data was evaluated.Findings related to Study 1 showed in general good agreement with the kinetic data published by Bruening et al. (2014). Contrarily, the peak ankle, midfoot and hallux powers published by Saraswat et al. (2014) are disputed. Findings of Study 2 revealed that the chopart joint encompasses both power absorption and generation, whereas the Lisfranc joint mainly contributes to power generation.The results highlights the necessity for further studies in the field of foot kinetic models and provides a first estimation of the kinetic behaviour of the Lisfranc joint.

International Sub commission on Stratigraphic Classification [Report No. 7b; editor H. D. Hedberg]: Summary of an International Guide to Stratigraphic Classification, Terminology, and Usage. Lethaia, Vol. 5, pp. 297–323. Oslo, July 15th, 1972. Six published reports (and some 40 circulars) of the International Sub commission on Stratigraphic Classification (ISSC) constitute the principal bases for the initial edition of an International Guide to Stratigraphic Classification, Terminology, and Usage. The published reports on Lithostratigraphic Units, Biostratigraphic Units, Chronostratigraphic Units, and Stratotypes are advance chapters of the Guide. The following Summary, which with the preceding Introduction will form the first chapter of the completed Guide, provides a concise and condensed statement of principles, definitions, and proposed rules, which are elaborated in more detail in the published reports and individual chapters of the Guide.     

Imitation of Body Movements Facilitated by Joint Attention through Eye Contact and Pointing in Japanese Monkey

Eye contact and pointing are typical gestures in order to direct another individual''s attention toward a target. We previously investigated on Japanese monkeys whether joint attention ability encouraged by eye contact and pointing was associated with the imitation of human''s actions. The monkeys with the joint attention skills showed the imitation of human''s actions. In the current study, we investigated on a monkey whether joint attention ability also facilitated the imitation of human body-movements. Results showed that the monkey being taught eye contact and pointing showed the imitation of human body-movements. These results suggest that the monkeys have basic potential for following another individual''s motion, and that what imitation expresses depends on where the monkeys are paying attention. Thus, eye contact and pointing are suitable for directing the monkey''s attention toward the human.     

THE SCOPE AND RESPONSIBILITY OF MEDICINE: A Forum with a Purpose

Many physicians and others are convinced that there is a pressing need for more discussion and more agreement concerning what ought to be the scope of medicine in today''s society. At the present moment, there is no general consensus either within or without the profession. Yet if the responsibility is ever to be met, its scope must be recognized and somehow defined.The editors of California Medicine propose to provide a forum in this journal for discussion of the scope and responsibility of medicine. This is a forum with a purpose, and so far as is known, an innovation in medical journalism. The forum is initiated with the statements beginning on the following page. Readers and others are invited to submit their views constructively and succinctly. As many of these as space permits will be published in future issues of California Medicine as a continuation of this forum. At an appropriate time all the material will be collated and, if feasible, the distillate will be prepared in the form of a statement on “The Scope and Responsibility of Medicine” to be submitted to the Council of the California Medical Association for its consideration.The statements which follow are the concisely expressed views of distinguished scholars, educators, statesmen and practitioners in the health field. It is hoped their views on this timely and important subject will provoke thought and comment among the readers of this journal     

Evaluation by Expert Dancers of a Robot That Performs Partnered Stepping via Haptic Interaction

Our long-term goal is to enable a robot to engage in partner dance for use in rehabilitation therapy, assessment, diagnosis, and scientific investigations of two-person whole-body motor coordination. Partner dance has been shown to improve balance and gait in people with Parkinson''s disease and in older adults, which motivates our work. During partner dance, dance couples rely heavily on haptic interaction to convey motor intent such as speed and direction. In this paper, we investigate the potential for a wheeled mobile robot with a human-like upper-body to perform partnered stepping with people based on the forces applied to its end effectors. Blindfolded expert dancers (N=10) performed a forward/backward walking step to a recorded drum beat while holding the robot''s end effectors. We varied the admittance gain of the robot''s mobile base controller and the stiffness of the robot''s arms. The robot followed the participants with low lag (M=224, SD=194 ms) across all trials. High admittance gain and high arm stiffness conditions resulted in significantly improved performance with respect to subjective and objective measures. Biomechanical measures such as the human hand to human sternum distance, center-of-mass of leader to center-of-mass of follower (CoM-CoM) distance, and interaction forces correlated with the expert dancers'' subjective ratings of their interactions with the robot, which were internally consistent (Cronbach''s α=0.92). In response to a final questionnaire, 1/10 expert dancers strongly agreed, 5/10 agreed, and 1/10 disagreed with the statement "The robot was a good follower." 2/10 strongly agreed, 3/10 agreed, and 2/10 disagreed with the statement "The robot was fun to dance with." The remaining participants were neutral with respect to these two questions.
