MIGRANTES TEMPORALES: RESIGNIFICACIÓN DE LAS NARRATIVAS

 El objetivo de este texto es el análisis de las narrativas de campesinos migrantes temporales, procedentes de dos regiones de fuerte emigración en Brasil: el estado de Paraíba, (situado en el nordeste del país), y el norte de Minas Gerais (situado en la región sudeste), donde se localiza el Vale do Rio Jequitinhonha. El estado de São Paulo es el principal destino de estos campesinos migrantes a causa de los extensos cañaverales que, actualmente, cubren un área de más de cinco millones de hectáreas. Son utilizadas también las narrativas de campesinos migrantes para la ciudad de São Paulo y de Rio de Janeiro. La metodología se basa en la Historia Oral. El eje principal de las reflexiones sostiene la idea de que no hay una desaparición de las narrativas causada por las constantes migraciones, sino una resignificación de las mismas, a partir de la experiencia migratoria. Palabras clave: Trabajo, emigración, narrativas.   Abstract The aim of this article is to analyse the narratives of  the temporary peasant migrants  from two important emigration regions in Brazil:  the State of Paraiba (located in the Northeast region) and  Vale of Jequitinhonha River in the North of Minas Gerais (located in the southeast region). The  main destination of the peasant migrants  is the sugar cane fields in the State of São Paulo, which covers over five millions of hectares of land. The narratives of peasant  migrants who go to the cities of São Paulo and Rio de Janeiro are also analysed in the article. The methodology is grounded on oral history. The main idea of the analysis  is that the narrative has not disappeared due to the permanent migrations, but there has been a re-interpretation of the narratives throughout the migration experience.

Cardiac Troponin T and Illness Severity in the Very-Low-Birth-Weight Infant

Introduction. Respiratory distress are very common in Very-low-birth-weight (VLBW) infants and Myocardial injury may play a role in the disease outcome. Cardiac troponin T (cTnT) is the most useful marker of injury in adult population, but has not been extensively studied in this population. Aim. To study the role of cTnT in VLBW infants and its association with clinical outcomes. Methods. All VLBW infants admitted to our NICU were included in the study. Echocardiography and blood samples for cTnT determination were collected at 24 and 48 hours of life, and values >0.1 ng/mL were considered CTnT-positive values. Results. A total of 116 neonates had their blood samples collected. The median cTnT concentration within 24 hours was 0.191 (0.1–0.79) ng/mL and within 48 hours was 0.293 (0.1–1.0) ng/mL. A logistic regression analysis showed that PDA, low GA, and use of dopamine were independently associated with positive cTnT and abnormal Dopplerfluxometry and diuretics use had protective effects and was independently associated with troponin values. Conclusion. We observed a high prevalence of positivecTnT values in VLBW infants associated with illness severity. Our findings suggest that cTnT may be a useful and early marker of myocardial injury in VLBW infants

PESQUISA E EXTENSÃO NA MODALIDADE DE ENSINO A DISTÂNCIA: A EXPERIÊNCIA DA LICENCIATURA EM TURISMO

O ensino a distância surge, no Brasil, como um projeto de ampliação de acesso ao nível superior, porém a garantia do tripé “ensino, pesquisa e extensão” ainda é um desafio para essa modalidade. O ensino a distância é mediatizado pela plataforma do ambiente virtual de aprendizagem (AVA) e por intermédio de tutores, materiais didáticos, polos e de ligações através de números 0800.Além de suscitar uma série de interessantes e relevantes debates acerca de formas de construção do conhecimento, pensar pesquisa e extensão em uma nova modalidade de ensino é rever as concepções filosóficas que permeiam o ensino como um todo. Através da contextualização do ensino a distância no Estado do Rio de Janeiro e do Curso de Licenciatura em Turismo,pretende-se refletir sobre o papel da pesquisa e extensão nesta modalidade, utilizando para tal a experiência em andamento dois projetos de pesquisa e extensão que estão sendo desenvolvidos

Avaliação de programa para reduzir dores nas costas em trabalhadores de enfermagem

OBJECTIVE: To evaluate the effectiveness of a program designed to reduce back pain in nursing aides. METHODS: Female nursing aides from a university hospital who had suffered episodes of back pain for at least six months were included in the study. Participants were randomly divided into a control group and an intervention group. The intervention program involved a set of exercises and an educational component stressing the ergonomic aspect, administered twice a week during working hours for four months. All subjects answered a structured questionnaire and the intensity of pain was assessed before and after the program using a visual analogue scale (VAS). Student's t-test or the Wilcoxon Rank Sum Test for independent samples, and Chi-square test or the Exact Fisher test for categorical analysis, were used. The McNemar test and the Wilcoxon matched pairs test were used to compare the periods before and after the program. RESULTS: There was a statistically significant decrease in the frequency of cervical pain in the last two months and in the last seven days in the intervention group. There was also a reduction in cervical pain intensity in the two periods (2 months, 7 days) and lumbar pain intensity in the last 7 days. CONCLUSIONS: The results suggest that a program of regular exercise with an emphasis on ergonomics can reduce musculoskeletal symptoms in nursing personnel.OBJETIVO: Avaliar o efeito de um programa na redução de dores nas costas em auxiliares de enfermagem. MÉTODOS: Participaram do estudo auxiliares de enfermagem com menos de 50 anos de idade, do sexo feminino, de um hospital universitário e que apresentavam dores nas costas por um período mínimo de 6 meses. O programa envolveu parte educativa, com abordagem ergonômica, e a realização de exercícios executados durante o horário de trabalho, duas vezes por semana, em um período de quatro meses. As participantes foram divididas aleatoriamente em grupo tratado e grupo controle. A intensidade das dores foi avaliada pela escala visual analógica. Foram utilizados os testes t de Student ou de Wilcoxon, para amostras independentes e os testes Qui-quadrado ou Exato de Fisher, para as categóricas. Para comparar as proporções do início e final do programa utilizou-se o teste de McNemar. RESULTADOS: Ocorreu diminuição estatisticamente significativa na freqüência de dor cervical durante os últimos dois meses e durante a ultima semana no grupo tratado. Houve também redução na intensidade da dor cervical em ambos os períodos (2 meses; 7 dias) e da dor lombar na última semana. CONCLUSÕES: O estudo sugere que programa regular de exercícios, acompanhado por abordagem instrucional ergonômica, pode reduzir sintomas músculo-esqueléticos em trabalhadores de enfermagem.35636

Social isolation disrupts hippocampal neurogenesis in young non-human primates

Social relationships are crucial for the development and maintenance of normal behavior in non-human primates. Animals that are raised in isolation develop abnormal patterns of behavior that persist even when they are later reunited with their parents. in rodents, social isolation is a stressful event and is associated with a decrease in hippocampal neurogenesis but considerably less is known about the effects of social isolation in non-human primates during the transition from adolescence to adulthood. To investigate how social isolation affects young marmosets, these were isolated from other members of the colony for 1 or 3 weeks and evaluated for alterations in their behavior and hippocampal cell proliferation. We found that anxiety-related behaviors like scent-marking and locomotor activity increased after social isolation when compared to baseline levels. in agreement, grooming an indicative of attenuation of tension was reduced among isolated marmosets. These results were consistent with increased cortisol levels after 1 and 3 weeks of isolation. After social isolation (1 or 3 weeks), reduced proliferation of neural cells in the subgranular zone of dentate granule cell layer was identified and a smaller proportion of BrdU-positive cells underwent neuronal fate (doublecortin labeling). Our data is consistent with the notion that social deprivation during the transition from adolescence to adulthood leads to stress and produces anxiety-like behaviors that in turn might affect neurogenesis and contribute to the deleterious consequences of prolonged stressful conditions.Universidade Federal de São Paulo, Dept Fisiol, BR-04023062 São Paulo, BrazilUniv Fed Rio Grande do Norte, Dept Fisiol, BR-59072970 Natal, RN, BrazilUniv Fed Rural Rio de Janeiro, Dept Ciencias Fisiol, Rio de Janeiro, BrazilUniversidade Federal de São Paulo, Dept Fisiol, BR-04023062 São Paulo, BrazilWeb of Scienc

Critical Education in Community Health Literacy for Brazilian Nurses: A Course Evaluation

This article presents an immediate evaluation of a professional development course in community health literacy for Brazilian nurses. An evaluation based on an applied thematic analysis of the accounts of 63 attendees in three Brazilian cities (January 2020) was guided by the following themes: (a) expansion of understanding about community health literacy as a pillar for planning and providing health care; (b) encouragement of innovation in research and/or practice; and (c) plans to incorporate the information shared in the course into professional projects. The evaluation disclosed the complexity of social contexts for health literacy, which is intertwined with ethnocultural diversity and deep socioeconomic disparities, such as restricted access to essential public health services for socially deprived and vulnerable individuals. Expanded understanding about community health literacy is a pillar for care planning and delivery, as well as innovation in research and practice projects. Participants’ evaluations revealed ideas to improve nurses’ practice in promoting community health literacy and empowerment, as well as quality of life and social well-being. Future knowledge dissemination may impact nurses’ clinical practice and management actions, bringing changes in various areas of practice to redesign more socially inclusive actions for clientele.

Laparoscopy versus laparotomy for FIGO stage 1 ovarian cancer (Review)

Background This is an updated version of the original review that was first published in the Cochrane Database of Systematic Reviews 2008, Issue 4. Laparoscopy has become an increasingly common approach to surgical staging of apparent early-stage ovarian tumours. This review was undertaken to assess the available evidence on the benefits and risks of laparoscopy compared with laparotomy for the management of International Federation of Gynaecology and Obstetrics (FIGO) stage I ovarian cancer. Objectives To evaluate the benefits and risks of laparoscopy compared with laparotomy for the surgical treatment of FIGO stage I ovarian cancer (stages Ia, Ib and Ic). Search methods For the original review, we searched the Cochrane Gynaecological Cancer Group Trials (CGCRG) Register, Cochrane Central Register of Controlled Trials (CENTRAL 2007, Issue 2), MEDLINE, EMBASE, LILACS, Biological Abstracts and CancerLit from 1 January 1990 to 30 November 2007. We also handsearched relevant journals, reference lists of identified studies and conference abstracts. For this updated review, we extended the CGCRG Specialised Register, CENTRAL, MEDLINE, EMBASE and LILACS searches to 6 December 2011. Selection criteria Randomised controlled trials (RCTs), quasi-RCTs and prospective cohort studies comparing laparoscopic staging with open surgery (laparotomy) in women with stage I ovarian cancer according to FIGO. Data collection and analysis There were no studies to include, therefore we tabulated data from non-randomised studies (NRS) for discussion. Main results We performed no meta-analyses. Authors’ conclusions This review has found no good-quality evidence to help quantify the risks and benefits of laparoscopy for the management of earlystage ovarian cancer as routine clinical practice
