Calculations of energy levels, radiative rates and lifetimes are reported for 17 F-like ions with 37≤Z≤53. For brevity, results are only presented among the lowest 113 levels of the 2s22p5, 2s2p6, 2s22p43ℓ, 2s2p53ℓ, and 2p63ℓ configurations, although the calculations have been performed for up to 501 levels in each ion. The general-purpose relativistic atomic structure package (grasp) has been adopted for the calculations, and radiative rates (along with oscillator strengths and line strengths) are listed for all E1, E2, M1, and M2 transitions of the ions. Comparisons are made with earlier available experimental and theoretical energies, although these are limited to only a few levels for most ions. Therefore for additional accuracy assessments, particularly for energy levels, analogous calculations have been performed with the Flexible Atomic Code (fac), for up to 72 259 levels. Limited previous results are available for radiative rates for comparison purposes, and no large discrepancy is observed for any transition and/or ion.

BACKGROUND: Prostate cancer might have high radiation-fraction sensitivity that would give a therapeutic advantage to hypofractionated treatment. We present a pre-planned analysis of the efficacy and side-effects of a randomised trial comparing conventional and hypofractionated radiotherapy after 5 years follow-up.

METHODS: CHHiP is a randomised, phase 3, non-inferiority trial that recruited men with localised prostate cancer (pT1b-T3aN0M0). Patients were randomly assigned (1:1:1) to conventional (74 Gy delivered in 37 fractions over 7·4 weeks) or one of two hypofractionated schedules (60 Gy in 20 fractions over 4 weeks or 57 Gy in 19 fractions over 3·8 weeks) all delivered with intensity-modulated techniques. Most patients were given radiotherapy with 3-6 months of neoadjuvant and concurrent androgen suppression. Randomisation was by computer-generated random permuted blocks, stratified by National Comprehensive Cancer Network (NCCN) risk group and radiotherapy treatment centre, and treatment allocation was not masked. The primary endpoint was time to biochemical or clinical failure; the critical hazard ratio (HR) for non-inferiority was 1·208. Analysis was by intention to treat. Long-term follow-up continues. The CHHiP trial is registered as an International Standard Randomised Controlled Trial, number ISRCTN97182923.

FINDINGS: Between Oct 18, 2002, and June 17, 2011, 3216 men were enrolled from 71 centres and randomly assigned (74 Gy group, 1065 patients; 60 Gy group, 1074 patients; 57 Gy group, 1077 patients). Median follow-up was 62·4 months (IQR 53·9-77·0). The proportion of patients who were biochemical or clinical failure free at 5 years was 88·3% (95% CI 86·0-90·2) in the 74 Gy group, 90·6% (88·5-92·3) in the 60 Gy group, and 85·9% (83·4-88·0) in the 57 Gy group. 60 Gy was non-inferior to 74 Gy (HR 0·84 [90% CI 0·68-1·03], pNI=0·0018) but non-inferiority could not be claimed for 57 Gy compared with 74 Gy (HR 1·20 [0·99-1·46], pNI=0·48). Long-term side-effects were similar in the hypofractionated groups compared with the conventional group. There were no significant differences in either the proportion or cumulative incidence of side-effects 5 years after treatment using three clinician-reported as well as patient-reported outcome measures. The estimated cumulative 5 year incidence of Radiation Therapy Oncology Group (RTOG) grade 2 or worse bowel and bladder adverse events was 13·7% (111 events) and 9·1% (66 events) in the 74 Gy group, 11·9% (105 events) and 11·7% (88 events) in the 60 Gy group, 11·3% (95 events) and 6·6% (57 events) in the 57 Gy group, respectively. No treatment-related deaths were reported.

INTERPRETATION: Hypofractionated radiotherapy using 60 Gy in 20 fractions is non-inferior to conventional fractionation using 74 Gy in 37 fractions and is recommended as a new standard of care for external-beam radiotherapy of localised prostate cancer.

Background The use of simulation in medical education is increasing, with students taught and assessed using simulated patients and manikins. Medical students at Queen’s University of Belfast are taught advanced life support cardiopulmonary resuscitation as part of the undergraduate curriculum. Teaching and feedback in these skills have been developed in Queen’s University with high-fidelity manikins. This study aimed to evaluate the effectiveness of video compared to verbal feedback in assessment of student cardiopulmonary resuscitation performance Methods Final year students participated in this study using a high-fidelity manikin, in the Clinical Skills Centre, Queen’s University Belfast. Cohort A received verbal feedback only on their performance and cohort B received video feedback only. Video analysis using ‘StudioCode’ software was distributed to students. Each group returned for a second scenario and evaluation 4 weeks later. An assessment tool was created for performance assessment, which included individual skill and global score evaluation. Results One hundred thirty eight final year medical students completed the study. 62 % were female and the mean age was 23.9 years. Students having video feedback had significantly greater improvement in overall scores compared to those receiving verbal feedback (p = 0.006, 95 % CI: 2.8–15.8). Individual skills, including ventilation quality and global score were significantly better with video feedback (p = 0.002 and p < 0.001, respectively) when compared with cohort A. There was a positive change in overall score for cohort B from session one to session two (p < 0.001, 95 % CI: 6.3–15.8) indicating video feedback significantly benefited skill retention. In addition, using video feedback showed a significant improvement in the global score (p < 0.001, 95 % CI: 3.3–7.2) and drug administration timing (p = 0.004, 95 % CI: 0.7–3.8) of cohort B participants, from session one to session two. Conclusions There is increased use of simulation in medicine but a paucity of published data comparing feedback methods in cardiopulmonary resuscitation training. Our study shows the use of video feedback when teaching cardiopulmonary resuscitation is more effective than verbal feedback, and enhances skill retention. This is one of the first studies to demonstrate the benefit of video feedback in cardiopulmonary resuscitation teaching.

La enfermedad de Chagas, también conocida como tripanosomiasis americana o Mal de Chagas-Mazza, es una enfermedad parasitaria tropical, generalmente crónica, causada por el protozoo flagelado Trypanosoma cruzi. Esta enfermedad afecta mayormente a las zonas con un gran índice de pobreza, siendo un problema en El Salvador, por lo cual se realizó el estudio de búsqueda de triatóminos en el entorno familiar y presencia de la enfermedad de Chagas en la población de 5 a 15 años, caserío San Rafael, cantón Guanaste, municipio de Ciudad Barrios, departamento de San Miguel en el período de mayo a julio de 2014. Se plantearon como Objetivos Aplicar los indicadores entomológicos en los vectores capturados y las viviendas inspeccionadas donde habita la población de 5 a 15 años de edad del caserío San Rafael y determinar la presencia de la enfermedad de Chagas en la población de 5 a 15 años de edad. La Metodología empleada en el estudio es de tipo prospectivo de corte transversal, descriptivo, de campo y de laboratorio. La población estuvo formada por 63 menores de edad y 37 viviendas. Resultados de esta investigación son: respecto a las viviendas se estudiaron 37 casas donde residen menores de 5 a 15 años de edad, encontrándose en viviendas un total de 22 vectores transmisores de la enfermedad, de las cuales en 3 (13.6%) de estas se encontraron positivas al parásito Trypanosoma cruzi; favorece a la proliferación de este vector en la comunidad el tipo de construcción de las viviendas, en las cuales predominó las casas de pared, piso y tierra con adobe, tierra y teja y bahareque, tierra y teja, respectivamente En la población se examinaron a 63 menores entre 5 a 15 años, de estos se detectaron 9 casos sospechosos y confirmaron 6 casos positivos, lo que equivale al 9% a la presencia de la enfermedad de Chagas. Conclusiones Se estudiaron 37 viviendas dado que en ellas habitan menores de 5 a 15 años, 10 de estas se encuentran infectadas con el vector. Encontrando un total de 22 chinches con un porcentaje de 27.02% de infestación de vivienda por Triatoma dimidiata. Se realizó una búsqueda dentro de las viviendas, con un índice de infestación intradomiciliar de 27.02%. A pesar de la búsqueda exhaustiva realizada en el área peridomiciliar de las viviendas no se logró encontrar el vector por lo tanto el índice de infestación peridomiciliar es de 0.0%. Al realizar la compresión abdominal de los 22 triatóminos capturados 3 resultaron positivos a la presencia del parásito, obteniéndose el índice de infestación natural de T. cruzi de 13.6%. De las chinches positivas, 2 de ellas fueron encontradas en viviendas de menores que salieron negativos a las pruebas parasitológicas directas e indirectas. Un factor importante para la detección de la enfermedad es que la comunidad esté informada completamente sobre los signos y síntomas de esta, y así evitar que la enfermedad pase desapercibida.

A garantia da memória histórica do ensino em nível profissionalizante em enfermagem, na década de 1970, foi o objeto dessa investigação. Teve como objetivos descrever e analisar o contexto sócio-político e as circunstâncias históricas em que a Lei nº 5.692, de 12 de agosto de 1971, das Diretrizes e Bases da Educação Nacional, foi promulgada, bem como discutir as mudanças e desdobramentos dessa no ensino profissionalizante em enfermagem. Trata-se de estudo descritivo, qualitativo, exploratório e de natureza histórico-social, com base em análise documental. Optou-se pela Micro-história para dar sustentação teórica à discussão dos resultados dessa investigação, pois a análise dos documentos históricos, sob o prisma de que, embora não seja possível enxergar a sociedade inteira a partir de um fragmento social, é possível enxergar algo da realidade social que envolve o fragmento humano examinado. A delimitação das fontes históricas do estudo compreende o Acervo do Arquivo Histórico da Associação Brasileira de Enfermagem - Seção São Paulo; o Acervo documental sobre a ABEn/SP, existente no Centro Histórico Cultural da Enfermagem Ibero-Americana da Escola de Enfermagem da USP e a Série Documenta do Ministério da Educação e Cultura. A partir dessa LDB nº 5.692/71, o ensino de Enfermagem foi totalmente integrado ao sistema nacional de Educação e sua promulgação ocorreu durante a Ditadura Militar e a ideologia do “milagre econômico”. De acordo com essa ideologia, o sistema educacional brasileiro deveria adequar-se ao modelo econômico desenvolvimentista, com treinamento de pessoal de nível técnico, visando aumentar e baratear os recursos humanos para o trabalho. A ABEn, como entidade representativa dos interesses políticos e ideológicos dos profissionais da área, liderava os debates sobre as questões da formação dos recursos humanos na enfermagem, sendo que na década de 70 mais da metade do contingente de enfermagem era majoritariamente sem formação específica. Também por conta dessa realidade, houve iniciativas governamentais para tentar reverter essa situação. Apesar das questões do ensino da enfermagem não se encontrarem explicitadas no texto da LDB nº 5.692/71, os resultados deste trabalho revelaram que a legislação estudada teve desdobramentos nas decisões políticas no âmbito do ensino profissionalizante e, consequentemente, impactou sobre a formação dos profissionais de enfermagem.

Después de una laparotomía del 70 al 95de pacientes tienen algún grado de adherencias, las que se manifestarán dependiendo de su consistencia y ubicación con cuadros clínicos de obstrucción intestinal agudos o crónicos, dolor abdominal crónico de casa no bien definido, dispareunias, infertilidad. El tratar la causa y el lavado de cavidad peritoneal son puntales principales en el tratamiento de la inflamación peritoneal desencadenante de la formación de adherencias. Para el lavado los cristaloides son los más indicados y de ellos la solución salñina y el lactato de Ringer los más usados. El objetivo fue conocer la capacidad para disminuir la formación de adherencias intraabdominales con el uso de lactato de ringer en comparación con la solución salina al contacto con el peritoneo, en ausencia de patología abdominal, en ratas Wistar. Para esto se realizó un estudio experimental clínico controlado aleatorizado en ratas wistar de laboratorio, formando dos grupos de 38 especímenes en cada uno, que cumplan los criterios de inclusión y exclusión, a las cuales les introdujo 5cc, de lactato de ringer y el otro grupo 5cc de solución salina al 0.9a 37 grados Celsius en la cavidad abdominal por punción con aguja Verres. A las 6 semanas se sacrificó a los animales y se realizó una valoración de las adherencias con clasificación macroscópica y estudio microscópico. De 75 casos, 35 del grupo de Lactato de Ringer y 36 del grupo de Solución salina, solamente 3 (8,10) ratas del grupo de Lactato de Ringer y 3 (7,89) del grupo de Solución Salina presentaron adherencias intraperitoneales. RR: 0,97 (0,18-5,15)

Purpose: To synthesize and characterize S-alkylated/aralkylated 2-(1H-indol-3-ylmethyl)-1,3,4- oxadiazole-5-thiol derivatives. Methods: 2-(1H-indol-3-yl)acetic acid (1) was reacted with absolute ethanol and catalytic amount of sulfuric acid to form ethyl 2-(1H-indol-3-yl)acetate (2) which was transformed to 2-(1H-indol-3- yl)acetohydrazide (3) by refluxing with hydrazine hydrate in methanol. Ring closure reaction of 3 with carbon disulfide and ethanolic potassium hydroxide yielded 2-(1H-indol-3-ylmethyl)-1,3,4-oxadiazole-5- thiol (4) which was finally treated with alkyl/aralkyl halides (5a-u) in DMF and NaH to yield Salkylated/ aralkylated 2-(1H-indol-3-ylmethyl)-1,3,4-oxadiazole-5-thiols (6a-u). Structural elucidation was done by IR, 1H-NMR and EI-MS techniques Results: 2-(1H-indol-3-ylmethyl)-1,3,4-oxadiazole-5-thiol (4) was synthesized as the parent molecule and was characterized by IR and the spectrum showed peaks resonating at (cm-1) 2925 (Ar-H), 2250 (S-H ), 1593 (C=N ) and 1527 (Ar C=C ); 1H-NMR spectrum showed signals at δ 11.00 (s, 1H, NH-1ʹ), 7.49 ( br.d, J = 7.6 Hz, 1H, H-4\'), 7.37 (br.d, J = 8.0 Hz, 1H, H-7\'), 7.34 (br.s, 1H, H-2\'), 7.09 (t, J = 7.6 Hz, 1H, H-5\'), 7.00 (t, J = 7.6 Hz, 1H, H-6\') and 4.20 (s, 2H, CH2-10ʹ). EI-MS presented different fragments peaks at m/z 233 (C11H9N3OS)˙+ [M+2]+, 231 (C11H9N3OS)˙+ [M]+, 158 (C10H8NO)+, 156 (C10H8N2)˙+, 130 (C9H8N)+. The derivatives (6a-6u) were prepared and characterized accordingly. Conclusion: S-alkylated/aralkylated 2-(1H-indol-3-ylmethyl)-1,3,4-oxadiazole-5-thiols (6a-u) were successfully synthesized.

Curatorial considerations, aims and objectives:The title for this exhibition (37 ° South to 19 ° North) refers to the Latitude of Melbourne, Australia and Cuernavaca, Mexico.My curatorial objective for making such a reference to the geographical was to invoke a sense of both distance and connection between the two locations of Australia and Mexico and to also create a sense of sharing, not only between our distant landscapes and cultures but also between the feelings and emotions that we all experience in response to the places in which we live out the moments which make up our daily lives.In developing this project I considered the work of more than 35 contemporary Australian photographers and finally selected 15 photographers (including myself). Most of these artists have or have had close connection to Melbourne and to the southern/eastern line of Australian continent. The final selection ranged from Hobart to Maroochydore and one artist who had lived in Melbourne for many years but was now living in Mexico. These photographers (and the specific works) were selected because their long term creative practice captures a sense of location (place and space) with a deep introspective sensibility which I feel offers a viewer a personal and softly spoken vision of some particular aspect of an Australian location, be that exterior landscape or interior place and a sense of unique connection to such places. These images are not documents but rather representations of feelings, stories, memories and dreams which emerge in the milieu of our inhabitants.In selecting the works, careful consideration was also given to diversity of approaches to photographic practice in conjunction to thematic content. Formats and media included black and white, pin hole photography, toy camera, large format (both 4” x 5” and 10”x 8”), phone camera, various digital camera images and other experimental approaches. The local art scene in Cuernavaca is very strong and there is a strong interest in photography. This is partially due to the number of local arts schools and universities which offer studies in photography as well as the political dimension regarding Mexican art in general - as a tool of both political media, reportage and documentary work, photography is a significant medium for many of the people who would be visiting the exhibition. I therefore felt it was important to address the diversity of approaches to the medium which are currently being explored by Australian practitioners.The City Museum of Cuernavaca provided two large walls and some smaller sections of side walls on both the grounds level and the upper level of the main museum galleries for exhibition.The works were arranged with a simple thematic structure. Top level, left to right, then bottom level, left to right starting with images which presented a sense of wilderness and landscape (which were also quite abstract and reductive) to more representational landscape images moving to landscape with small figures (people) emerging within the images (Ash Kerr) to landscapes with larger figures and the emerging presence of man-made elements to urban landscapes and then to interior urban scapes and finally to interior locations with people and finally finishing on the metaphorical image by Harry Nankin of Bogong Moths and the politics of climate change. (It is also interesting to note that the migration path of the Bongong moth matches well the distribution of the artists selected for this project)Broadly speaking the images started outside with broad landscape to intimate interior locations. With these works a great deal of personal content from each photographer was presented. Most artists chose to present 3 large format images while some only presented 2 images. Other graphic and visual elements were considered in the final placement of the images.It must also be noted that the artists selected ranged broadly from very highly established and significant local artists to mid-career/younger establishing artist to some lesser known and emerging artists. From a curatorial perspective I feel this is offers the possibility of what I shall term, a more balanced representation of the local Australian practice and it provides a context in which both established and emerging artists / works must engage on a dialogue, within the exhibition. I believe it also placing the curatorial premise on the strength of the work rather than on whom the artists are and their status. It also supports the younger emerging artists and provides a less formal and predictable outcome for the established artists and for as a collective presentation as a whole.

Un enfant qui développe ses habiletés motrices par le biais d'une pratique d'activités physiques régulière améliore sa santé en général, mais aussi ses chances de maintenir de saines habitudes de vie à l’âge adulte. L’acquisition des habiletés motrices par l’enfant contribue non seulement à son développement physique et moteur, mais aussi cognitif, affectif et social. L’environnement dans lequel l’enfant évolue est un facteur d’une grande influence face à sa pratique de l’activité physique et au développement de ses habiletés motrices. À cet égard, l’environnement familial et le modèle parental sont des vecteurs motivationnels majeurs face à l’attitude que l’enfant adoptera quant à sa pratique d’activités physiques au quotidien. À ce jour, peu d’études ont évalué les effets d’interventions menées auprès des parents visant à favoriser la pratique d’activités physiques et le développement des habiletés motrices. Le but du présent projet de recherche consistait à évaluer les effets d’une intervention menée auprès des parents visant à augmenter la pratique d’activités physiques et le degré d’habiletés motrices chez des enfants âgés de 3 à 5 ans fréquentant un milieu de garde. Nous voulions aussi déterminer si la perception des parents avait changé face à l’importance de l’activité physique et du développement des habiletés motrices chez leur enfant. À cette fin, nous avons procédé à une étude quasi expérimentale en étudiant le comportement de 37 enfants provenant de trois milieux de garde de la région de Coaticook en Estrie. Les données ont été recueillies par le biais d’un calendrier d’activité physique et d’un questionnaire pré et post intervention. Les résultats de ce projet de recherche montrent que les enfants d’âge préscolaire Coaticokois font en moyenne 28 minutes d’activités physiques par jour lorsqu’ils se retrouvent à la maison auprès de leurs parents. De plus, seulement 31 % des activités physiques et motrices effectuées par les enfants ont été vécues en présence de leurs parents. Les résultats de ce projet de recherche indiquent également un effet temps et un effet groupe non significatifs avec des enfants n’ayant pas démontré des signes de progression face au développement de leurs habiletés motrices. Par contre, les enfants du groupe intervention ayant reçu un calendrier avec des suggestions d’activités physiques et motrices ont expérimenté plus d’activités de manipulation d’objets que les enfants du groupe contrôle n’ayant pas eu cette opportunité. Les parents du groupe intervention ont notamment mentionné avoir été influencés par la présence d’un calendrier avec des activités physiques et motrices suggérées, ce qui reflète bien les résultats précédemment indiqués. En comparant nos résultats avec les recommandations de 120 minutes par jour d’activités physiques du National Association for Sport and Physical Education, NASPE (2009) et celles de la Société Canadienne de Physiologie de l’Exercice, SCPE (2012) qui suggère 180 minutes d’activités physiques par jour, et ce, peu importe l’intensité déployée par l’enfant, on peut conclure que les enfants de ce projet de recherche n’atteignent pas ces recommandations. Nous demeurons convaincus du bien-fondé d’une intervention menée auprès des parents afin d’améliorer la pratique d’activités physiques des enfants d’âge préscolaire, notamment si une collaboration plus étroite est effectuée avec ces derniers. Cependant, de nombreuses autres études sur le sujet seront nécessaires pour constater quel type d’intervention est le plus efficace afin de favoriser la pratique d’activités physiques et d’améliorer le degré d’habiletés motrices chez des enfants âgés de 3 à 5 ans.

Introducción: Siendo la desnutrición infantil, un indicador trazador en el perfil de salud de una población y prioridad establecida por los objetivos de desarrollo del milenio y el plan decenal de salud pública en Colombia - PDSP en su dimensión de seguridad alimentaria y nutricional, mantiene gran prevalencia a nivel nacional a pesar de presentar subregistro en la información reportada, por ende, es prioridad la medición, notificación y tratamiento de la misma. La OMS estandarizó los parámetros de medición y el gobierno nacional los adoptó mediante la resolución 2121 de 2010. Sin embargo, para disminuir el indicador de desnutrición que al año 2015 debería estar reducido en un 50% según el PDSP, es necesario identificar el sub registro que hay en el diagnóstico de la misma. Metodología: Se realizó un estudio poblacional, descriptivo y transversal, en el cual se analizó la base de datos de los niños menores de 5 años asistentes a consulta de crecimiento y desarrollo en una institución de salud del municipio de Puerto Inírida, con el fin de realizar una caracterización nutricional basados en mediciones antropométricas y contrastándolas realizadas por los profesionales de salud con las encontradas utilizando los patrones establecidos por la OMS. La información se analizó con el Software WHO Anthro propiedad de la OMS. Resultados: Se encontró que el 33,6% de los menores de 5 años registrados presentan desnutrición crónica, el 7,6% desnutrición aguda, el 13,2% de desnutrición global y el 13,9% tiene obesidad. Al discriminarlo por edad se encontró mayor prevalencia de desnutrición crónica en ambos sexos, siendo mayor en población de sexo masculino (40,1% masculino – 27,6% femenino); al igual que al realizar la comparación por pertenencia puesto que se encuentra la misma prevalencia en desnutrición crónica (29,1% en población indígena y 29% en población no indígena). Según los estándares de la OMS, en la población estudiada 12 se identificaron 243 casos de malnutrición, mientras que en la consulta de crecimiento y desarrollo fueron diagnosticados como casos de malnutrición por los profesionales de salud solo 99. Discusión: La malnutrición es un problema estructural, por ende, se deben tener en cuenta factores tanto intrínsecos como extrínsecos de la persona. Las medidas antropométricas son sólo una manera de medir, que se debe contextualizar con el entorno y las condiciones socioeconómicas, patológicas y culturales en las que se encuentre la población. El estado nutricional de los menores asistentes a los controles de crecimiento y desarrollo de la población estudiada, se encuentra mal registrado, de la misma manera se encontró una gran prevalencia de desnutrición crónica que es un determinante en la calidad de vida. Es imperante la implementación de políticas públicas adecuadas que permitan profundizar en las causas de este flagelo y así mismo en su tratamiento.
