Clinician characteristics, communication, and patient outcome in oncology: a systematic review.

OBJECTIVE: The aim of this study was to review the literature on clinician characteristics influencing patient-clinician communication or patient outcome in oncology. METHODS: Studies investigating the association of clinician characteristics with quality of communication and with outcome for adult cancer patients were systematically searched in MEDLINE, PSYINFO, PUBMED, EMBASE, CINHAL, Web of Science and The Cochrane Library up to November 2012. We used the preferred reporting items for systematic reviews and meta-analyses statement to guide our review. Articles were extracted independently by two of the authors using predefined criteria. RESULTS: Twenty seven articles met the inclusion criteria. Clinician characteristics included a variety of sociodemographic, relational, and personal characteristics. A positive impact on quality of communication and/or patient outcome was reported for communication skills training, an external locus of control, empathy, a socioemotional approach, shared decision-making style, higher anxiety, and defensiveness. A negative impact was reported for increased level of fatigue and burnout and expression of worry. Professional experience of clinicians was not related to communication and/or to patient outcome, and divergent results were reported for clinician gender, age, stress, posture, and confidence or self-efficacy. CONCLUSIONS: Various clinician characteristics have different effects on quality of communication and/or patient outcome. Research is needed to investigate the pathways leading to effective communication between clinicians and patients. Copyright © 2013 John Wiley & Sons, Ltd.

Impacte visual aeri a Argentona

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit cientí­fic del Jovent l'any 2009. Aquest treball té com a finalitat millorar l'entorn aeri d'Argentona, un poble situat a la comarca del Maresme. Els elements que creen més impacte visual aeri són les antenes en desús i el cablejat no soterrat. S'han buscat propostes per canviar aquesta situació: la retirada de les antenes, aprofitant l'arribada de la TDT, i el soterrament del cablejat aeri. Donat que ambdues accions afectarien al municipi i a la seva població, s'ha considerat necessari incloure una enquesta, per a conèixer l'opinió dels argentonins, i dues entrevistes, a l'alcalde i a l'enginyer municipal, per conèixer la postura oficial.

Spatio-temporal gait analysis in children with cerebral palsy using, foot-worn inertial sensors.

A child's natural gait pattern may be affected by the gait laboratory environment. Wearable devices using body-worn sensors have been developed for gait analysis. The purpose of this study was to validate and explore the use of foot-worn inertial sensors for the measurement of selected spatio-temporal parameters, based on the 3D foot trajectory, in independently walking children with cerebral palsy (CP). We performed a case control study with 14 children with CP aged 6-15 years old and 15 age-matched controls. Accuracy and precision of the foot-worn device were measured using an optical motion capture system as the reference system. Mean accuracy±precision for both groups was 3.4±4.6cm for stride length, 4.3±4.2cm/s for speed and 0.5±2.9° for strike angle. Longer stance and shorter swing phases with an increase in double support were observed in children with CP (p=0.001). Stride length, speed and peak angular velocity during swing were decreased in paretic limbs, with significant differences in strike and lift-off angles. Children with cerebral palsy showed significantly higher inter-stride variability (measured by their coefficient of variation) for speed, stride length, swing and stance. During turning trajectories speed and stride length decreased significantly (p<0.01) for both groups, whereas stance increased significantly (p<0.01) in CP children only. Foot-worn inertial sensors allowed us to analyze gait spatiotemporal data outside a laboratory environment with good accuracy and precision and congruent results with what is known of gait variations during linear walking in children with CP.

Effects of a dual inhibitor of angiotensin converting enzyme and neutral endopeptidase, MDL 100,240, on endocrine and renal functions in healthy volunteers.

OBJECTIVE: To investigate the endocrine and renal effects of the dual inhibitor of angiotensin converting enzyme and neutral endopeptidase, MDL 100,240. DESIGN: A randomized, placebo-controlled, crossover study was performed in 12 healthy volunteers. METHODS: MDL 100,240 was administered intravenously over 20 min at single doses of 6.25 and 25 mg in subjects with a sodium intake of 280 (n = 6) or 80 (n = 6) mmol/day. Measurements were taken of supine and standing blood pressure, plasma angiotensin converting enzyme activity, angiotensin II, atrial natriuretic peptide, urinary atrial natriuretic peptide and cyclic GMP excretion, effective renal plasma flow and the glomerular filtration rate as p-aminohippurate and inulin clearances, electrolytes and segmental tubular function by endogenous lithium clearance. RESULTS: Supine systolic blood pressure was consistently decreased by MDL 100,240, particularly after the high dose and during the low-salt intake. Diastolic blood pressure and heart rate did not change. Plasma angiotensin converting enzyme activity decreased rapidly and dose-dependently. In both the high- and the low-salt treatment groups, plasma angiotensin II levels fell and renin activity rose accordingly, while plasma atrial natriuretic peptide levels remained unchanged. In contrast, urinary atrial natriuretic peptide excretion increased dose-dependently under both diets, as did urinary cyclic GMP excretion. Effective renal plasma flow and the glomerular filtration rate did not change. The urinary flow rate increased markedly during the first 2 h following administration of either dose of MDL 100,240 (P < 0.001) and, similarly, sodium excretion tended to increase from 0 to 4 h after the dose (P = 0.07). Potassium excretion remained stable. Proximal and distal fractional sodium reabsorption were not significantly altered by the treatment. Uric acid excretion was increased. The safety and clinical tolerance of MDL 100,240 were good. CONCLUSIONS: The increased fall in blood pressure in normal volunteers together with the preservation of renal hemodynamics and the increased urinary volume, atrial natriuretic peptide and cyclic GMP excretion distinguish MDL 100,240 as a double-enzyme inhibitor from inhibitors of the angiotensin converting enzyme alone. The differences appear to be due, at least in part, to increased renal exposure to atrial natriuretic peptide following neutral endopeptidase blockade.

Major impact of body position on arterial stiffness indices derived from radial applanation tonometry in pregnant and nonpregnant women.

OBJECTIVE: To evaluate the impact of body position on the arterial stiffness indices provided by radial applanation tonometry in pregnant and nonpregnant women. METHODS: Twenty-four young women (18-30 years) in the third trimester of a normal pregnancy and 20 healthy nonpregnant women of the same age were enrolled. In each, applanation tonometry was carried out in the sitting and supine position. The following stiffness indices were analyzed: systolic augmentation index (sAix), sAix adjusted for heart rate (sAix@75) and diastolic augmentation index (dAix), all expressed in % of central aortic pulse pressure. RESULTS: The sAix was apparently not influenced by body position, but the transition from seated to supine was associated with a substantial decrease in heart rate. When correcting for this confounder by calculating the sAix@75, systolic augmentation was substantially lower when individuals were supine (mean ± SD: nonpregnant 3.0 ± 14.4%, pregnant 8.8 ± 9.7%) than when they were sitting (nonpregnant 5.7 ± 13.0%, pregnant 11.1 ± 83%, P = 0.005 supine vs. seated in both study groups, P > 0.2 for pregnant vs. nonpregnant). The influence of body position on the dAix went in the opposite direction (supine: nonpregnant 9.7 ± 6.6%, pregnant 4.4 ± 3.5%; seated: nonpregnant 7.7 ± 5.8%, pregnant 3.3 ± 2.4%, P < 0.00001 supine vs. seated in both study groups, P = 0.001 for pregnant vs. nonpregnant). CONCLUSION: Body position has a major impact on the pattern of central aortic pressure augmentation by reflected waves in healthy young women examined either during third trimester pregnancy or in the nonpregnant state.

Multi-segment foot kinematics after total ankle replacement and ankle arthrodesis during relatively long-distance gait.

This study aimed to investigate the influence of ankle osteoarthritis (AOA) treatments, i.e., ankle arthrodesis (AA) and total ankle replacement (TAR), on the kinematics of multi-segment foot and ankle complex during relatively long-distance gait. Forty-five subjects in four groups (AOA, AA, TAR, and control) were equipped with a wearable system consisting of inertial sensors installed on the tibia, calcaneus, and medial metatarsals. The subjects walked 50-m twice while the system measured the kinematic parameters of their multi-segment foot: the range of motion of joints between tibia, calcaneus, and medial metatarsals in three anatomical planes, and the peaks of angular velocity of these segments in the sagittal plane. These parameters were then compared among the four groups. It was observed that the range of motion and peak of angular velocities generally improved after TAR and were similar to the control subjects. However, unlike AOA and TAR, AA imposed impairments in the range of motion in the coronal plane for both the tibia-calcaneus and tibia-metatarsals joints. In general, the kinematic parameters showed significant correlation with established clinical scales (FFI and AOFAS), which shows their convergent validity. Based on the kinematic parameters of multi-segment foot during 50-m gait, this study showed significant improvements in foot mobility after TAR, but several significant impairments remained after AA.

Performer par le dispositif ? Un retour critique sur la théorie de la performativité.

L'objectif de cet article est de revenir sur un point saillant de la théorie de la performativité des énoncés économiques, c'est-à-dire l'importance qu'elle accorde aux dispositifs techniques dans l'explication de l'influence des théories économiques sur le monde social. Cette démarche débouche sur le refus de mobiliser les catégories sociales (institution, convention, norme sociale, etc.) dans les explications qu'elle produit. On soulignera ici l'origine de cette posture épistémologique, la théorie de l'acteur-réseau, avant d'en faire la critique. On montrera principalement que penser les dispositifs techniques nécessite impérativement de les penser au sein d'un contexte conventionnel particulier. Dès lors, le rejet des catégories sociales est épistémologiquement contre-productif dans les études de performativité

Maurice Blanchot: autonomie et responsabilité (1944-1948)

RÉSUMÉ En conjuguant les méthodes de l'histoire littéraire, de la sociologie des champs et de l'analyse littéraire, ce mémoire se propose d'étudier l'élaboration de la « posture » de Maurice Blanchot dans l'immédiat après-guerre (1944-1948). Le passé de Blanchot, marqué par des positions politiques d'extrême droite dans les années 30, et dans une certaine mesure encore sous l'Occupation, le conduit à un repositionnement conséquent dans le champ littéraire de la Libération marqué par l'Epuration des écrivains collaborateurs. Ce repositionnement se traduit par l'élaboration de la « posture » de l'écrivain en retrait, qui se présente comme la manifestation d'une autonomie littéraire radicale. Toutefois, cette posture du retrait demeure une forme de participation au champ littéraire et Blanchot, malgré sa volonté d'une parfaite autonomie de son oeuvre vis-à-vis des impératifs économiques ou idéologiques du temps, n'en est pas moins amené à réélaborer ses postulats critiques de même que sa production proprement dite (Le Très-Haut, L'Arrêt de mort), en interaction avec les nouvelles forces dominantes du champ littéraire de la Libération. Il est notamment conduit à se positionner vis-à-vis de la nouvelle avant-garde qui a émergé de la Résistance, dominée par Sartre et ses Temps Modernes, qui promeut un nouveau modèle, celui de l'écrivain engagé.

Statistical evaluation of the influence of writing postures on on-line signatures. Study of the impact of time.

The aim of this study is to investigate the influence of unusual writing positions on a person's signature, in comparison to a standard writing position. Ten writers were asked to sign their signature six times, in each of four different writing positions, including the standard one. In order to take into consideration the effect of the day-to-day variation, this same process was repeated over 12 sessions, giving a total of 288 signatures per subject. The signatures were collected simultaneously in an off-line and on-line acquisition mode, using an interactive tablet and a ballpoint pen. Unidimensional variables (height to width ratio; time with or without in air displacement) and time-dependent variables (pressure; X and Y coordinates; altitude and azimuth angles) were extracted from each signature. For the unidimensional variables, the position effect was assessed through ANOVA and Dunnett contrast tests. Concerning the time-dependent variables, the signatures were compared by using dynamic time warping, and the position effect was evaluated through classification by linear discriminant analysis. Both of these variables provided similar results: no general tendency regarding the position factor could be highlighted. The influence of the position factor varies according to the subject as well as the variable studied. The impact of the session factor was shown to cover the impact that could be ascribed to the writing position factor. Indeed, the day-to-day variation has a greater effect than the position factor on the studied signature variables. The results of this study suggest guidelines for best practice in the area of signature comparisons and demonstrate the importance of a signature collection procedure covering an adequate number of sampling sessions, with a sufficient number of samples per session.

Stress radiography and posterior pathological laxity of knee: comparison between two different techniques.

Stress radiographs have been recommended in order to obtain a better objective quantification of abnormal compartment knee motion. This tool has showed to be superior in quantifying a posterior cruciate ligament (PCL) lesion compared to clinical or arthrometer evaluation. Different radiographic techniques have been described in literature to quantify posterior pathological laxity. In this study we evaluated the total amount of posterior displacement (PTD) and side to side difference (SSD), before and after surgical reconstruction of PCL or PCL and posterolateral complex (PLC), using two different stress radiography techniques (Telos stress and kneeling view). Twenty patients were included in this study. We found a statistical significant difference about both total PTD and SSD among the two techniques preoperatively and at follow-up, with greatest values occurring using the kneeling view. Although stress radiographies has been introduced to allow an objective quantification of laxity in ligamentous injured knee, we believe that further studies on a large numbers of subjects are required to define the relationship between PTD values, measured with stress knee radiography, particularly using kneeling view, and ligamentous knee injury, in order to obtain a real useful tool in the decision making process, as well as to evaluate the outcome after ligamentous surgery.

Daisy Roots Garden Project

In the summer of 2009 a local Men’s group that met in St Helena’s thought that it might be a good idea to sow a wild garden on the site.  Then came the raised beds – 2 were placed in the garden area opposite the front door of the house and as it was winter there was not much happening and they were quickly renamed the ‘coffins’.  This was the start of ‘Daisy Roots’. Dublin City Council provided top soil and water butts.  An Taisce funded the start up phase of the project and now continue to provide funds for insurance and some development work.  At the right hand side of St Helena’s there is, what was the old stable yard of the ‘big house’.  This had been used to house a large ‘lock up container and a porta-cabin.  These have been now removed and this is where the main part of the garden is. Following a conference of Business in the Community Ireland, DX Ltd expressed an interest in getting involved in a local project.  Together DX staff and the volunteers reclaimed the old stables and gave them new roofs and new doors.  Paths were put in between the raised vegetable beds and new raised beds were built.  A seating area was developed.  The garden is now wheelchair accessible and there are wheelchair accessible flowerbeds in the garden also.  The newest projects in the garden are a memorial flowerbed and a propagator.

Effective exposure to solar UV in building workers: influence of local and individual factors.

Excessive exposure to solar UV light is the main cause of skin cancers in humans. UV exposure depends on environmental as well as individual factors related to activity. Although outdoor occupational activities contribute significantly to the individual dose received, data on effective exposure are scarce and limited to a few occupations. A study was undertaken in order to assess effective short-term exposure among building workers and characterize the influence of individual and local factors on exposure. The effective exposure of construction workers in a mountainous area in the southern part of Switzerland was investigated through short-term dosimetry (97 dosimeters). Three altitudes, of about 500, 1500 and 2500 m were considered. Individual measurements over 20 working periods were performed using Spore film dosimeters on five body locations. The postural activity of workers was concomitantly recorded and static UV measurements were also performed. Effective exposure among building workers was high and exceeded occupational recommendations, for all individuals for at least one body location. The mean daily UV dose in plain was 11.9 SED (0.0-31.3 SED), in middle mountain 21.4 SED (6.6-46.8 SED) and in high mountain 28.6 SED (0.0-91.1 SED). Measured doses between workers and anatomical locations exhibited a high variability, stressing the role of local exposure conditions and individual factors. Short-term effective exposure ranged between 0 and 200% of ambient irradiation, indicating the occurrence of intense, subacute exposures. A predictive irradiation model was developed to investigate the role of individual factors. Posture and orientation were found to account for at least 38% of the total variance of relative individual exposure, and were also found to account more than altitude on the total variance of effective daily exposures. Targeted sensitization actions through professional information channels and specific prevention messages are recommended. Altitude outdoor workers should also benefit from preventive medical examination.
