Toque terapêutico no cuidado da enfermagem: uma análise conceitual

Objective: To analyze the concept of therapeutic touch in nursing care, specifying its attributes, antecedents, and consequents. Methods: This is a conceptual analysis of the evolutive view of Rodgers (2000), about the concept of therapeutic touch in nursing care, together with an integrative literature review based on the research question: What is the concept of therapeutic touch in nursing care? What are the attributes, antecedents, and consequents of therapeutic touch in nursing care? The search was conducted in the electronic databases CINAHL Complete, MEDLINE Complete, Nursing & Allied Health Collection: Comprehensive, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Library, Information Science & Technology Abstracts, MedicLatina, in the b-on Online Knowledge Library, by combining the descriptors DeCS/MESH “therapeutic touch”, “nursing” e “nursing care” and the Boolean operator AND over the period from 2000 to 2020. Results: The sample was composed of eight studies that identified three thematic pillars: (i) attributes: complementary and effective method, technique, tool, nursing intervention, use of hands, intention to help or heal, complementary treatment, intentional touch, and energy transfer; (ii) antecedents: pain, anxiety, fatigue, dementia, Alzheimer’s disease, tension headache, fibromyalgia syndrome, and cardiovascular problems; (iii) consequents: promotes a calming effect; increases empathy, satisfaction, interaction, respect, sense of worth and life; promotes well-being, comfort, tranquility and peace, hope, security, motivation, mood and sleep quality; reduces stress and disruptive behaviors; promotes better functional status and quality of life. Conclusion: Therapeutic touch is implicit in the professional practice of nurses, requiring concrete and unique adjustment to the real circumstances and needs of the person, towards a practice that promotes comfort.Objetivo: Analisar o conceito de toque terapêutico no cuidado de enfermagem, especificando seus atributos, antecedentes e consequentes.

Resultados: A amostra foi formada por oito estudos que identificaram três pilares temáticos: (i) atributos: método complementar e eficaz, técnica, ferramenta, intervenção de enfermagem, uso de mãos, intenção de ajudar ou curar, tratamento complementar, toque intencional e transferência de energia; (ii) antecedentes: dor, ansiedade, fadiga, demência, doença de Alzheimer, cefaleia de tensão, síndrome de fibromialgia e problemas cardiovasculares; (iii) consequentes: promove um efeito calmante; aumenta a empatia, satisfação, interação, respeito, senso de valor e vida; promove bem-estar, conforto, tranquilidade e paz, esperança, segurança, motivação, humor e qualidade do sono; reduz o estresse e comportamentos perturbadores; promove melhor estado funcional e qualidade de vida. Conclusão: O toque terapêutico está implícito na prática profissional dos enfermeiros, exigindo um ajuste concreto e singular às circunstâncias e necessidades reais da pessoa, em favor de uma prática que promova o conforto.info:eu-repo/semantics/publishedVersio

COMMUNICATION AND THE PERCEPTION OF RISK IN THE INFLUENCE OF BEHAVIORS

The Effect of Lycopene Preexposure on UV-B-Irradiated Human Keratinocytes

Lycopene has been reported as the antioxidant most quickly depleted in skin upon UV irradiation, and thus it might play a protective role. Our goal was to investigate the effects of preexposure to lycopene on UV-B-irradiated skin cells. Cells were exposed for 24 h to 10 M lycopene, and subsequently irradiated and left to recover for another 24 h period. Thereafter, several parameters were analyzed by FCM and RT-PCR: genotoxicity/clastogenicity by assessing the cell cycle distribution; apoptosis by performing the Annexin-V assay and analyzing gene expression of apoptosis biomarkers; and oxidative stress by ROS quantification. Lycopene did not significantly affect the profile of apoptotic, necrotic and viable cells in nonirradiated cells neither showed cytostatic effects. However, irradiated cells previously treated with lycopene showed an increase in both dead and viable subpopulations compared to nonexposed irradiated cells. In irradiated cells, lycopene preexposure resulted in overexpression of BAX gene compared to nonexposed irradiated cells. This was accompanied by a cell cycle delay at S-phase transition and consequent decrease of cells in G0/G1 phase. Thus, lycopene seems to play a corrective role in irradiated cells depending on the level of photodamage. Thus, our findings may have implications for the management of skin cancer

Cycloartane triterpenes from Euphorbia tuckeyana

Investigation of the acetone extract of the whole plant of Euphorbia tuckeyana afforded a new cycloartane-type triterpene named as cyclotucanol. Its structure was established as cycloartane-24-methylene-3beta,25-diol (1). The known cycloartane triterpenes cycloeucalenol (2), 3,8-hydroxy-cycloart-25-en-24-one (3), cycloart-25-ene-3beta,24-diol (4), 25,26,27-trisnor-3beta-hydroxycycloartan-24-al (5) and cycloart-23-ene-3beta,25-diol (6) were also isolated and identified
