Late migration of percutaneous bio-absorbable devices--a word of caution.

BACKGROUND: Closures of atrial septal defects or a patent foramen ovale (PFO) are increasingly performed percutaneously. The experience of late migration of a new bio-absorbable device is presented here, followed by conceptual discussion. METHODS: Six months post PFO closure with a BioSTAR® device a patient presented with chest pain. Echocardiography showed a hyperechogenic structure perforating the aortic wall. RESULTS: Surgical exploration showed a perforation of the ascending aorta by one metallic, non absorbable arm. This is the second case of late (>6 months) dislocation of the residual framework of the occluder. CONCLUSIONS: The overall incidence of perforation of cardiac structures due to secondary dislocation is low. However this complication exists and should kept in mind in symptomatic patients with new onset of chest pain, after percutaneous procedures. The concept of biodegradation, with residual, non absorbable metal braiding, should be reviewed, analyzing in particular long term results and incidence of secondary dislocation.

Histone deacetylase inhibitors repress macrophage migration inhibitory factor (MIF) expression by targeting MIF gene transcription through a local chromatin deacetylation.

The cytokine macrophage migration inhibitory factor plays a central role in inflammation, cell proliferation and tumorigenesis. Moreover, macrophage migration inhibitory factor levels correlate with tumor aggressiveness and metastatic potential. Histone deacetylase inhibitors are potent antitumor agents recently introduced in the clinic. Therefore, we hypothesized that macrophage migration inhibitory factor would represent a target of histone deacetylase inhibitors. Confirming our hypothesis, we report that histone deacetylase inhibitors of various chemical classes strongly inhibited macrophage migration inhibitory factor expression in a broad range of cell lines, in primary cells and in vivo. Nuclear run on, transient transfection with macrophage migration inhibitory factor promoter reporter constructs and transduction with macrophage migration inhibitory factor expressing adenovirus demonstrated that trichostatin A (a prototypical histone deacetylase inhibitor) inhibited endogenous, but not episomal, MIF gene transcription. Interestingly, trichostatin A induced a local and specific deacetylation of macrophage migration inhibitory factor promoter-associated H3 and H4 histones which did not affect chromatin accessibility but was associated with an impaired recruitment of RNA polymerase II and Sp1 and CREB transcription factors required for basal MIF gene transcription. Altogether, this study describes a new molecular mechanism by which histone deacetylase inhibitors inhibit MIF gene expression, and suggests that macrophage migration inhibitory factor inhibition by histone deacetylase inhibitors may contribute to the antitumorigenic effects of histone deacetylase inhibitors.

Polymorphisms of the " macrophage migration inhibitory factor " gene in infectious diseases

Summary The proinflammatory cytokine macrophage migration inhibitory factor (MIF) has emerged as a central mediator of inflammation and innate immune defense against infections. MIF has been shown to play an important role in the pathogenesis of infectious diseases like sepsis, tuberculosis and autoimmune inflammatory diseases, such as arthritis, inflammatory bowel disease and asthma. Two functional polymorphisms of the MIF gene promoter, a five to eight CATT repeat microsatellite at position -794 and a G/C SNP at position -173, have been associated with increased susceptibility to or severity of autoimmune inflammatory diseases like arthritis, colitis and atopy. The aim of this thesis was to define whether, and if so by which mechanisms, MIF gene polymorphisms influence the susceptibility to or the outcome of one of the most severe and one of the most prevalent infectious diseases: meningococcal sepsis and tuberculosis, respectively. The results of the comparison between 1106 patients suffering from severe meningococcal infections and 434 healthy volunteers showed that carriers of the CATT5-5 genotype were protected from meningococcemia. A transmission disequilibrium test involving 106 families confirmed this association. At baseline and after stimulation with Neisseria meningitidis, the CATT5 MIF promoter drove lower transcriptional activity than the CATT6 or CATT7 alleles in human monocytic cells and whole blood of CATT5-5 healthy individuals tended to produce less MIF than whole blood of CATT6-6 individuals. Beyond, we describe several new MIF gene polymorphisms in Africans. Genotyping the CATT microsatellite and the -173*G/C SNP revealed great genetic diversity in six African ethnic groups. Comparing 471 African tuberculosis cases and 932 matched healthy controls, we observed ethnicity dependent associations of the -173*G/C and the CATT5-8 with susceptibility to or severity of tuberculosis, but confirmation in larger cohorts ìs needed. In conclusion, we report that homozygous carriage of a low expression allele of the MIF gene protects from meningococcal disease. These results support the concept that analyses of MIF genotypes in patients with sepsis may help to classify patients into risk categories and to identify those patients who may benefit from anti-MIF therapeutic strategies.

Teaching-service integration: implications and roles in experiences of Undergraduate Courses in Nursing

The study aimed at understanding the implications of the teaching-service integration to nursing education from the perspective of teachers, students and professionals in Primary Healthcare as well as identifying the roles of teachers and professionals who follow practical experiences in education. This is a case study of qualitative approach carried out in five undergraduate courses in Nursing in the state of Santa Catarina. A total of 22 teachers and 14 professionals were interviewed and five focus groups were conducted with students. Results are presented in two categories: Implications of the teaching-service integration to education in Nursing: contributing factors and intervening factors and Relationships established in the experiences: a unison speech and a dissonant practice. The contributions of the teaching-service integration are undeniable. Despite this belief, there are intervening factors that need to be on the agenda for discussion. The role of facilitator in education emerged strongly despite conflicting perceptions remain.

Nurses, nursing technicians and assistants: who experiences more moral distress?

Objective: To identify the frequency and intensity of moral distress experienced by nurses, technicians and nursing assistants who worked in hospitals in the South of Rio Grande do Sul State. Method: A survey research was conducted with 334 nursing workers from three institutions, through a questionnaire of moral distress. Constructs were validated through factorial analysis and Cronbach’s alpha: lack of competence of the working team, disrespect to the patient’s autonomy, insufficient working conditions and therapeutic obstinacy. Results: With descriptive statistics and analysis of variance, it was found that nurses and nursing assistants have higher perception of moral distress when compared to nursing technicians. Organizational questions and ways of communication influence lower perception of moral distress.Conclusion: Implementation of actions to favor coping, decision making and autonomy exercise from those workers.


Child Health Booklet: experiences of professionals in primary health care

Objective: Understanding the experiences of health professionals in primary care with the Child Health Booklet in child health care. Method: A qualitative study with a phenomenological approach, in which participated nurses and doctors from six teams of the Family Health Strategy (FHS) in Belo Horizonte, MG. In total, were carried out 12 non-directive interviews, using two guiding questions. Results: A comprehensive analysis of the speeches enabled the construction of three categories that signal the experiences of the professionals with the booklet. The experiments revealed difficulties arising from the limitations of knowledge about the instrument; incomplete filling out of the booklet by many professionals that care for children; the daily confrontations of the process and the organization of work teams; disinterest of families with the instrument. Conclusion: The research points possible and necessary ways to improve the use of booklets as an instrument of full child health surveillance.

Regulation of the immune response by macrophage migration inhibitory factor: biological and structural features.

The classical T cell cytokine macrophage migration inhibitory factor (MIF) has reemerged recently as a critical mediator of the host immune and stress response. MIF has been found to be a mediator of several diseases including gram-negative septic shock and delayed-type hypersensitivity reactions. Its immunological functions include the modulation of the host macrophage and T and B cell response. In contrast to other known cytokines, MIF production is induced rather than suppressed by glucocorticoids, and MIF has been found to override the immunosuppressive effects of glucocorticoids. Recently, elucidation of the three-dimensional structure of MIF revealed that MIF has a novel, unique cytokine structure. Here the biological role of MIF is reviewed in view of its distinct immunological and structural properties.

BETWEEN DREAMS AND REALITY: Migration of Brazilian women to Switzerland

The general objective of this article was to study the process of illegal migration of Brazilian women to Switzerland and, more specifically, to analyze the motivations for migration, the difficulties found upon arrival, the circumstances that led them to get married and lastly an evaluation of the whole experience. The methodology was based in a qualitative approach. The participants were eight Brazilian women that illegally migrated to Switzerland but now are married with Swiss or European men. They responded to an interview focused in the objectives of the study. The appreciation of the data was realized with Minayo´s Content Analysis. The motivations were related to a bettering of the financial situation. In the difficulties encountered, we can bring out illegality, language and prejudice. Regarding marriage, they married to stay legally in the country. Finally, the evaluation of the experience was negative for most participants.

Understanding the experiences of caregivers of children with tuberculosis in directly observed therapy

Objective To understand the situations and communications experienced by caregivers of children with tuberculosis (TB) with regard to directly observed therapy (DOT). Method A descriptive exploratory study with a qualitative approach was applied and developed in the ambulatory of Programa Einstein na Comunidade de Paraisópolis (PECP). The data were collected using semi-structured interviews of 13 caregivers of children with TB in DOT. The Collective Subject Discourse (CSD) method was used to analyze the data. Results Seven CSDs were identified and grouped into four categories: "Living in a difficult situation", "Changing the family routine", "Responsibility almost always fall son the mother", and "Adapting to the DOT". Conclusions The difficulties faced by the caregiver of the child at the beginning of DOT significantly changed the familiar routine. The responsibility for its continuity was assigned to the mother, who must adapt to the demands of the treatment and face the situation.

Supplemental nursing staff´s experiences at a Spanish hospital: Qualitative phenomenology research

The objective of this study was to describe the Supplemental Nursing Staff´s experiences at different hospital units. A qualitative phenomenological approach was conducted; a purposeful and theoretical sampling was implemented with supplemental nursing staff at Santa Barbara Hospital of Soria (Spain), to gain a more in-depth understanding of the Supplemental Nursing Staff ´s experience. Data were collected by in-depth interviews and through a field notebook. Data were analyzed using the Giorgi proposal. Twenty-one nurses with a mean age of 46 years were included. Three main topics emerged from the data analysis: building the first contact, carving out a niche and establishing interprofessional/interpersonal relationships. We conclude that the experience of hosting the supplemental nursing staff in changing clinical environments is conditioned by various factors. It is necessary for nurses and hospital managers to establish clear objectives with regard to the supplemental nursing staff´s role in the units.

PERCEPTIONS AND EXPERIENCES OF ELDERLY RESIDENTS IN A NURSING HOME

The objective of this study was to evaluate the perception of the elderly residents of a long-stay nursing home on the process of institutionalization. We interviewed 14 subjects, five women and nine men, aged between 60 and 92 years. Data collection was conducted with a semi-structured sociodemographic interview, which presented the guiding question: “Tell me about how is your life, what do you do and how did you come to live here”. From the analysis, we found topics related to feelings of abandonment, loneliness, anger, ingratitude, living with chronic pain, satisfaction of property in the nursing home, productivity and social relationship. Given the thematic analysis, it was possible to group them into three categories such as: what the elderly feel, what the elderly perceive and what the elderly desire. As a result, we need public policies that addresses to the service provided by institutions regarding elderly expectations.

Unwanted sexual experiences among adolescents: shedding light on the gray zone between consensual and non-consensual sex.

This study aimed at exploring adolescents' perceptions of unwanted sexual experiences (USE) in order to set up definitions, categories, and boundaries on the continuum between consensual and non-consensual sex. METHODS: We conducted a qualitative thematic analysis of four focus group discussions gathering a total of 29 male and female adolescents aged 16-20 years. RESULTS: Analysis of participants' discourse revealed three main characteristics that define USE, namely, regret, as most situations discussed were said to be acceptable or not in terms of whether there were regrets after the fact; misperception of sexual intent; and lack of communication between partners. CONCLUSIONS: Our findings revealed that health professionals should be aware of the subtle aspects identifying USE when screening for situations that can have adverse psychological consequences. Where prevention is concerned, it appears important to address these aspects of USE in sex education classes.

The (un)receptive experiences of female rape victims who seek healthcare services

OBJECTIVE To know the structure and functioning of healthcare services from the perspective of women who have suffered rape. METHOD A qualitative study conducted with 11 women who experienced rape, monitored in a maternity in the state of Alagoas, Brazil. Data were systematically based on content analysis. RESULTS It allowed for understanding the path taken by women in search of support from health services, as well as the limitations and capabilities of these services. CONCLUSION The assistance received in healthcare services leans towards a revictimization process of women who already carry trauma from the rape. It is necessary to reflect about care practices aimed at sexually victimized women.

Life experiences of elderly with cancer pain: the existential comprehensive approach

OBJECTIVE Understanding the experiences of elderly with cancer pain. METHOD Qualitative research based on Heidegger's phenomenology. 12 elderly cancer patients from a city in northwest Paraná were interviewed from November 2013 to February 2014. RESULTS Analysis performed by vague, median and interpretive understanding which resulted in two ontological themes: Cancer pain: unveiling the imprisonment and impositions experienced by the elderly, and Unveiling the anguish of living with cancer pain; it revealed not only how the elderly experience pain in their daily lives, but also how hard it is to live with its particularities. CONCLUSION Cancer pain has biopsychosocial repercussions for the elderly, generating changes in their existence in the world, requiring holistic and authentic care.
