Revisão sistemática do efeito do envelhecimento no andar livre e adaptativo

Aging seems to impair the walking. However, it is not clear the effects of aging on walking. The aim of this study was to determine changes in kinematic, kinetic and electromyographic parameters of the free and adaptive gait, in preferred velocity, caused by aging. The initial search strategy was performed to identify all articles that examined the free and adaptive gait. The electronic databases analyzed were: MEDLINE, PubMed, EMBASE, CINAHL, Sports Discus, DARE, PsychInfo, ERIC, AusportMed, AMI, Cochrane and PEDro. Twenty-three articles were reviewed in full. Elderly are slower, with shorter step length and longer double support duration than young adults during free and adaptive gait. Even, they showed higher muscular demands, with redistribution of joint power and torque and decreased force in the propulsion and absorption phases. It was concluded that elderly present altered kinematic, kinetic and electromyographic parameters of free and adaptive gait compared to young adults.

Prevalence of recurrent wheezing and its risk factors

Objective: analyze the prevalence of recurrent wheezing and its risk factors. Method: systematic literature review, guided by the research question “what is the prevalence of recurrent wheezing and its risk factors?”. The search was performed in the databases MedLine and LILACS, in April and May 2013. The inclusion criteria were: scientific study, fully available, published between 2002 and 2013, with free access. Results: wheezing presents a higher prevalence in developing countries, possibly due to poor socioeconomic conditions. Among its risk factors, we find heredity, mother’s education level, attendance of day nursery, smoking during pregnancy, breastfeeding for < 3 months, animals in the household of children, among others. Conclusion: in Latin America, the prevalence of wheezing shows to be high and the use of non-standardized instruments hampers its treatment.

Care to mastectomy with axillary lymphadenectomy, lymphedema prevention: An integrative review

Objective: to examine the care provided to women affected by breast cancer and who has performed axillary lymphadenectomy. Method: integrative review conducted in the databases LILACS and PubMed between 2000 and 2012, leaving the question << What care is provided to prevent lymphedema in women who underwent lymphadenectomy? >> Resulting in 18 articles, analyzed under the following variables: author, title, methodology, year, journal, goal, prevention and control of lymphedema therapies and adherence to rehabilitation. Results: three categories are identified for rehabilitation of patient: prevention and control, therapies and adherence. Conclusion: preoperative is poorly addressed by; emphasizes the importance of home visits as part of rehabilitation, which is effective with the accession of the patient who needs information for its follow-up, no need for a guideline for this type treatment.

O contexto de indexação para catalogação de livros usando uma abordagem sociognitiva

We evaluated study of the indexing process in the cataloging at university libraries, using a socio-cognitive approach to analyze procedures, difficulties and perceptions of librarians, users, and managers. The methodology consisted of the Individual and Group Verbal Protocols applied in university libraries. The results were the absence of procedures for book subject analysis and representation, incompatibility of indexing language, and problems of subject retrieval from the catalog. We have concluded that is tendency of catalogs to act as databases. Therefore, the cataloguer should present a posture of commitment similar to that of an indexer who works in the production of these bases.

Integrative aspects of the relationship between stress and heart rate variability

The literature indicates stress as a response of the organism to a stimulation that requires enormous efforts to adapt to the changes in the environment and the body. When an individual is subjected to stress, the autonomic nervous system is triggered, the sympathetic pathway is activated, and the parasympathetic system is suppressed, which exerts several effects on the cardiovascular system and affects heart rate variability. This research aimed to conduct a literature review to find and analyze the studies that address clearly the implications of stress on heart rate variability. The methodology employed was an active search in the databases SciELO, PubMed and Lilacs. The results were five articles, most of which suggest a relationship between stress and heart rate variability. We observed that the majority of the studies indicated a strong association between stress and cardiac autonomic activity. The stress is present in the daily activities of the population, especially in labor. The subject is vast, however, were observed in the references the effects of stress on the body making it vulnerable to diseases. Thus, this information may contribute to the aid of preventive strategies against stress and diseases of the cardiovascular system.

Modelos de recuperação de informação e web semântica: a questão da relevância

Introduction: In the Web environment, there is a need for greater care with regard to the processing of descriptive and thematic information. The concern with the recovery of information in computer systems precedes the development of the first personal computers. Models of information retrieval have been and are today widely used in databases specific to a field whose scope is known. Objectives: Verify how the issue of relevance is treated in the main computer models of information retrieval and, especially, as the issue is addressed in the future of the Web, the called Semantic Web. Methodology: Bibliographical research. Results: In the classical models studied here, it was realized that the main concern is retrieving documents whose description is closest to the search expression used by the user, which does not necessarily imply that this really needs. In semantic retrieval is the use of ontologies, feature that extends the user's search for a wider range of possible relevant options. Conclusions: The relevance is a subjective judgment and inherent to the user, it will depend on the interaction with the system and especially the fact that he expects to recover in your search. Systems that are based on a model of relevance are not popular, because it requires greater interaction and depend on the user's disposal. The Semantic Web is so far the initiative more efficient in the case of information retrieval in the digital environment.

O impacto do Método Mãe Canguru no processo de aprendizagem de prematuros de baixo peso: Revisão da literatura

Technology advances and scientific studies in Neonatal Intensive Care Units (NICU) have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB). However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC) were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011), that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL), a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

Efeitos da Ventilação Mecânica não Invasiva sobre a Modulação Autonômica Cardíaca

This review is intended to gather together recent studies that explore the effects of different types of noninvasive ventilation (NIV) on the autonomic nervous system, assessed through heart rate variability (HRV). A search for papers was conducted in the PubMed, PEDro, SciELO and Lilacs databases with the following descriptors: noninvasive ventilation, CPAP ventilation, intermittent positive pressure breathing and autonomic nervous system, for the period between 2008 and 2012. After eliminating papers not addressing the topic, we selected six studies, of which five applied NIV in CPAP mode and one used biphasic positive airway pressure. In general, the findings suggest that NIV promotes changes in autonomic modulation that are dependent on the conditions of the subjects analyzed and the time when these rates are assessed, meaning acute or long-term effects.
