Public speaking: view from master's students in nursing

A comunicação é um instrumento básico de trabalho dos enfermeiros, no entanto falar em público é uma situação temida por muitos profissionais. Este trabalho teve como objetivos descrever as emoções sentidas pelos enfermeiros mestrandos e identificar como planejam a apresentação e o que consideram importante para falar em público. Participaram do estudo cinquenta enfermeiros matriculados no mestrado da EEUSP. A coleta de dados deu-se através de questionário com perguntas abertas. Os resultados mostraram que a ansiedade foi a emoção mais freqüente citada pelos enfermeiros, no planejamento o domínio do conteúdo foi o aspecto mais relatado e falar com clareza foi a característica mais valorizada para quem fala em público.Communication is a basic element of Nursing; still, speaking in public can be a frightening experience for many nurses. This article intends to study the emotions felt by Master's studentes in Nursing, identifying how they plan their presentation and whatthey consider important enough to reveal to the public. Fifty nurses who were enrolled in the Master's program at EEUSP participated in the study. Data was collected through a questionaire utilizing open-answer questions. Results showed that anxiety was the most frequent emotion related by. them. In the planning of a presentation, however confidence in the content of the speaker's text was the most important aspect, while speaking clearly appeared as the most valued characteristic in general

Chemical Composition and Evaluation of Antitumoral Activity of Leaf and Root Essential Oils of Conyza canadensis (Asteraceae)

The leaf and root oils of Conyza canadensis were studied for chemical composition and antitumor activity. The results showed that there is great variation in the composition of the oils obtained from different parts. The main components in the leaf oil were limonene, caryophyllene oxide and espatulenol. In the root oil the major component was the acetylenic ester lachnophyllum methyl ester. It was observed that according to the collection time (6 and 16 hours), significant variations in the content of the main components of this essential oil of leaves can occur. Limonene, spatulenol and caryophyllene oxide presented a distribution of 61% / 5.4% / 12.5% ​​and 38% / 10.7% / 22.3% in oils obtained from plants collected at 6 and 16 hours, respectively. The antitumor activity of the oils showed that leaf oil had a greater potential for inhibition, and this oil was distinguished by the activity against neoplastic cell lines K562 (leukemia) and NCI-ADR / RES (ovary with multidrug resistance phenotype ) with TGI values ​​of 16.8 and 19.0 mg.mL-1, respectively. Comparing the leaf oils and their tumor cell inhibition potentials, it was noted that this activity is higher in the oil with higher contents of monoterpene limonene.

Measuring access to medicines: a review of quantitative methods used in household surveys

<p>Abstract</p> <p>Background</p> <p>Medicine access is an important goal of medicine policy; however the evaluation of medicine access is a subject under conceptual and methodological development. The aim of this study was to describe quantitative methodologies to measure medicine access on household level, access expressed as paid or unpaid medicine acquisition.</p> <p>Methods</p> <p>Searches were carried out in electronic databases and health institutional sites; within references from retrieved papers and by contacting authors.</p> <p>Results</p> <p>Nine papers were located. The methodologies of the studies presented differences in the recall period, recruitment of subjects and medicine access characterization.</p> <p>Conclusions</p> <p>The standardization of medicine access indicators and the definition of appropriate recall periods are required to evaluate different medicines and access dimensions, improving studies comparison. Besides, specific keywords must be established to allow future literature reviews about this topic.</p

Determination of βS haplotypes in patients with sickle-cell anemia in the state of Rio Grande do Norte, Brazil

βS haplotypes were studied in 47 non-related patients with sickle-cell anemia from the state of Rio Grande do Norte, Brazil. Molecular analysis was conducted by PCR/RFLP using restriction endonucleases XmnI, HindIII, HincII and HinfI to analyze six polymorphic sites from the beta cluster. Twenty-seven patients (57.5%) were identified with genotype CAR/CAR, 9 (19.1%) CAR/BEN, 6 (12.8%) CAR/CAM, 1 (2.1%) BEN/BEN, 2 (4.3%) CAR/Atp, 1 (2.1%) BEN/Atp and 1 (2.1%) with genotype Atp/Atp. The greater frequency of Cameroon haplotypes compared to other Brazilian states suggests the existence of a peculiarity of African origin in the state of Rio Grande do Norte
