Seroreactivity to new Mycobacterium leprae protein antigens in different leprosy-endemic regions in Brazil

New Mycobacterium leprae protein antigens can contribute to improved serologic tests for leprosy diagnosis/classification and multidrug therapy (MDT) monitoring. This study describes seroreactivity to M. leprae proteins among participants from three highly endemic leprosy areas in Brazil: central-western Goiânia/Goiás (GO) (n = 225), Rondonópolis/Mato Grosso (MT) (n = 764) and northern Prata Village/Pará (PA) (n = 93). ELISA was performed to detect IgG to proteins (92f, 46f, leprosy IDRI diagnostic-1, ML0405, ML1213) and IgM to phenolic glycolipid-I (PGL-I). Multibacillary (MB) leprosy had positive rates for PGL-I that were similar to those for proteins; however, some anti-PGL-I-negative subjects were positive for proteins, suggesting that adding protein antigen to PGL-I can enhance the sensitivity of MB leprosy detection. In MT, different degrees of seroreactivity were observed and ranked for MB, former patients after MDT, paucibacillary (PB) leprosy, household contact (HHC) and endemic control (EC) groups. The seroreactivity of PB patients was low in GO and MT. HHCs from different endemic sites had similar IgG antibody responses to proteins. 46f and 92f were not recognised by most tuberculosis patients, ECs or HHCs within GO, an area with high BCG vaccination coverage. Low positivity in EC and HHC was observed in PA and MT. Our results provide evidence for the development of an improved serologic test that could be widely applicable for MB leprosy testing in Brazil.

Genotyping of Mycobacterium leprae present on Ziehl-Neelsen-stained microscopic slides and in skin biopsy samples from leprosy patients in different geographic regions of Brazil

We analysed 16 variable number tandem repeats (VNTR) and three single-nucleotide polymorphisms (SNP) in Mycobacterium leprae present on 115 Ziehl-Neelsen (Z-N)-stained slides and in 51 skin biopsy samples derived from leprosy patients from Ceará (n = 23), Pernambuco (n = 41), Rio de Janeiro (n = 22) and Rondônia (RO) (n = 78). All skin biopsies yielded SNP-based genotypes, while 48 of the samples (94.1%) yielded complete VNTR genotypes. We evaluated two procedures for extracting M. leprae DNA from Z-N-stained slides: the first including Chelex and the other combining proteinase and sodium dodecyl sulfate. Of the 76 samples processed using the first procedure, 30.2% were positive for 16 or 15 VNTRs, whereas of the 39 samples processed using the second procedure, 28.2% yielded genotypes defined by at least 10 VNTRs. Combined VNTR and SNP analysis revealed large variability in genotypes, but a high prevalence of SNP genotype 4 in the Northeast Region of Brazil. Our observation of two samples from RO with an identical genotype and seven groups with similar genotypes, including four derived from residents of the same state or region, suggest a tendency to form groups according to the origin of the isolates. This study demonstrates the existence of geographically related M. leprae genotypes and that Z-N-stained slides are an alternative source for M. leprae genotyping.

Integrative Review: Concepts And Methods Used In Nursing


Integrative review (IR) has an international reputation in nursing research and evidence-based practice. This IR aimed at identifying and analyzing the concepts and methods recommended to undertaking IR in nursing. Nine information resources,including electronic databases and grey literature were searched. Seventeen studies were included. The results indicate that: primary studies were mostly from USA; it is possible to have several research questions or hypotheses and include primary studies in the review from different theoretical and methodological approaches; it is a type of review that can go beyond the analysis and synthesis of findings from primary studies allowing exploiting other research dimensions, and that presents potentialities for the development of new theories and new problems for research. Conclusion: IR is understood as a very complex type of review and it is expected to be developed using standardized and systematic methods to ensure the required rigor of scientific research and therefore the legitimacy of the established evidence.


Health-related quality of life among patients with advanced cancer: an integrative review

This integrative literature review aimed to characterize scientific articles on health-related quality of life – HRQoL – among patients with advanced cancer from national and international literature, and summarize those factors evidenced in the literature that contributed to the improvement or worsening of HRQoL among patients with advanced cancer. The search for materials was conducted in the following databases: CINAHL, EMBASE, PubMed, SciELO and LILACS. Among the 21 articles in the sample, 13 showed an improvement of HRQoL among patients with advanced cancer related to the development of physical, emotional and spiritual interventions. In eight studies, we identified predictive symptoms of low HRQoL, such as pain, fatigue, sleep disorders, depression, nutritional changes, and others. The results showed that clinical manifestations, which many times were inherent in cancer, such as factors that can lower patients’ HRQoL, while physical, psychological and spiritual benefits resulting from therapeutic interventions may promote its improvement.


Risk factors for falls in hospitalized adult patients: an integrative review

Objective: Identifying risk factors for the occurrence of falls in hospitalized adult patients. Method: Integrative review carried out in the databases of LILACS, SciELO, MEDLINE and Web of Science, including articles published between 1989 and 2012. Results: Seventy-one articles were included in the final sample. Risk factors for falls presented in this review were related to patients (intrinsic), the hospital setting and the working process of health professionals, especially in nursing (extrinsic). Conclusion: The systematic screening of risk factors for falls was identified as a contributing factor to the reduction of this injury, helping the non-occurrence of this event that, despite being preventable, can have serious consequences including death.


Risk factors associated with mental health issues in adolescents: a integrative review

Objective: To identify the risk factors associated with mental health issues in adolescents. Method: An integrative review was conducted in four databases with publications from 2007 to 2013. The terms Adolescent and Mental Health were used to search adequate articles as DeCs/MeSH bases. Results: Publications were found in different journals in different fields of knowledge and the quantitative research was the most frequent. The mental health issues were categorized as individual factors; drug related factors, school factors, family factors, social factors and STDs/Aids related factors. The most addressed category was individual factors, with 23 publications. Conclusion: The integrative review allowed to point important questions to be addressed in preventive actions by the health professional, including the nurse, to create a space that works with risk conditioning factors in adolescents for mental health aggravation.


Perceived self-image in adolescent idiopathic scoliosis: an integrative review of the literature

Objective: To learn about the experiences of adolescents diagnosed with idiopathic scoliosis. Method: Integrative review of the literature published within a specified time frame. Results: For both sexes, the predominant clinical symptom of this condition appears to be the negative effect that the deformity exerts on perceived self-image. Quantitative studies used numerical scores to assess perceptions of body image but did not analyse emotional aspects. Patients treated surgically were found to have a better self-image than patients treated with a brace. Quality of life was improved by a reduction in the magnitude of the curve. Conclusion: Spinal deformity exerts a psychological effect on adolescent girls.


Experience of spouses of women with breast cancer: an integrative literature review

Objective: To gather, to characterize, to analyze, to synthesize and to integrate primary studies that addressed the experiences of spouses / husbands / partners of women with breast cancer, presenting the current state of knowledge. Method: Integrative literature review carried out in the databases of VHL, PubMed, CINHAL e SciELO. Results: The sample consisted of eight studies published between 2000-2012, which pointed to the experiences of the involvement and the care of the husbands towards their ill wives. Conclusion: This study highlights the need for attention and assistance to those spouses, as well as guidance and education to exercise the care the same way as the health staff has done with women. Furthermore, it emphasizes the importance of further studies in order to deepen the knowledge on this topic, and thus, improve the care with better scientific basis.

The work environment and leadership in nursing: an integrative review

Objective: To investigate the relationship between the work environment and leadership in nursing. Method: An integrative review of literature which was based on data from LILACS, PubMed, CINAHL and the SciELO portal for journals covering the period from January to April 2013. The inclusion criteria were: the indexing of research covering leadership exercised by nurses over a team and whether the research was available in English, Spanish or Portuguese. Results: The sample consisted of 12 articles that met the criteria. Conclusion: The results showed that leadership had an impact on the work environment. However, no studies were found that showed the influence of the working environment on leadership in nursing.

Educational technologies designed to promote cardiovascular health in adults: integrative review

Objective Investigating the educational technologies developed for promoting cardiovascular health in adults. Method Integrative review carried out in the databases of PubMed, SciELO and LILACS, with 15 articles selected. Results Over half (60%) of the studies were randomized clinical trials. The developed educational technologies were programs involving three strategies, with duration of one year, use of playful technologies with storytelling, computer programs or software for smartphones, and electronic brochure. These technologies resulted in reduction of blood pressure, weight, waist circumference, decreased hospitalizations and increased years of life. Conclusion The studies with better impact on the cardiovascular health of adults were those who brought the technology in the form of program and duration of one year.

Methodological approach for the development of terminology subsets ICNP®: an integrative review

Objective To analyze the methodological aspects used for the preparation of terminology subsets of the International Classification for Nursing Practice (ICNP®), in dissertations and theses in the Brazilian nursing. Method This is an integrative review of the Brazilian dissertations and theses defended in the period from 2007 to 2013, which were included seven dissertations. Results The increasing production of studies on the theme by Brazilian nurses shows a concern for a unified language for the profession. However, the results demonstrate the lack of uniformity in the conduct of studies, especially in relation to the stages of content validation. The initiatives of some authors to systematize alternative methods for creating these subsets also stood out. Conclusion We suggest the development of new terminology subsets, following standards of methodological rigor, as well as its application and validation by the selected clientele, to ensure greater reliability of results and desired changes for the profession.

Therapeutic Listening as a health intervention strategy: an integrative review

Objective To investigate and evaluate the available evidence in the literature regarding the use of Therapeutic Listening as a health intervention strategy. Method Integrative review conducted on the following databases PubMed, CINAHL, The Cochrane Library, EMBASE, LILACS and APA PsycNET without restrictions of year or type of study. The keywords were combined in different ways to ensure extensive search of primary studies. Results Among the 15 studies on Therapeutic Listening, 33% addressed the effect of training on listening skills, 27% focused on the efficacy of listening as an intervention, 20% explored the experiences lived by the subjects regarding listening and 20% discussed various aspects of listening. Conclusion Most studies have strong to moderate level of evidence, although addressing different aspects related to Therapeutic Listening, they have in common the need for recognition of skills on the part of health professionals, to develop an effective process of listening.


Difficulties of familes in caring for children and adolescents with mental disorders: an integrative review

Objective To identify the difficulties of families with children and/or adolescents with mental disorder. Method This is an integrative review. In December 2013, an electronic search was performed on Latin American Caribbean Literature on Health Sciences databases (LILACS) and on Electronic Medicus Index of the National Library of Medicine (MEDLINE) indexed in the Health Virtual Library (BVS) using a combination of descriptors and boolean operators as follows: mental disorders and child or adolescent and caregivers and/not health staff. Results 557 studies were identified, of which 15 were selected for this study. The findings indicated difficulties related to the care for or to interaction with children/adolescents with mental disorder. Conclusion The studies revealed difficulties related to everyday practices of care and feelings expressed during care practices, as well as in relationships with children or adolescents with mental disorder.



Ethical dimension of circle Integrative Community Therapy on qualitative research

This study discusses ethical issues in research involving human beings and seeks to understand the relationship between qualitative research and the ethical care guidelines for Integrative Community Therapy (ICT) circles based on Resolution 466/12 of the National Health Council of the Ministry of Health of Brazil. This is documentary research, which analyzed Resolution 466/12 and ICT circles seeking to make a connection between the ethical guidelines contained in both. The analysis of the corpus was directed toward the construction of the following results: the person's perception, cultural diversity and community. It also brings in consideration of the influence of the ethical dimension of the ICT circles on qualitative research. We conclude that ICT circles are innovative in the sense of the diversity of participants and respect for cultural and social differences. Thus, ICT circles promote acquisition of quality information for social research as well as compliance with the ethical guidelines outlined in Resolution No. 466/12.

Strategies for self-management support by patients with stroke: integrative review

OBJECTIVE To analyze strategies for self-management support by patients with stroke in the light of the methodology of the five A's (ask, advice, assess, assist and arrange). METHODS Integrative review conducted at the following databases CINAHL, SCOPUS, PubMed, Cochrane and LILACS. RESULTS A total of 43 studies published between 2000 and 2013 comprised the study sample. All proposed actions in the five A's methodology and others were included. We highlight the Assist and Arrange, in which we added actions, especially with regard to the use of technological resources and joint monitoring between patients, families and professionals. No study included all five A's, which suggests that the actions of supported self-management are developed in a fragmented way. CONCLUSION The use of five A's strategy provides guidelines for better management of patients with stroke with lower cost and higher effectiveness.
