Facilitators of the transition process for the self-care of the person with stoma: subsidies for Nursing

OBJECTIVE To know the facilitating factors of the transition process from dependency to the self-care of people with a stoma. METHOD This is a descriptive study of qualitative approach, including 27 people with permanent stomas due to cancer. The data were collected through semi-structured interviews and submitted to content analysis based on the Transition Theory as theoretical reference. RESULTS The self-care facilitators related to the person were the positive significance of ostomy; the preparation for this experience already in the preoperative period; emotional stability; faith; religiousness; and a sense of normalcy acquired from a next image similar to the previous one. The facilitators related to the community were the following: receiving equipment for free from the government; support from family and the multidisciplinary team, especially the nurses; and having contact with other people with stomata. CONCLUSION The results allow that nurses develop strategies to help people with stomata to resume their self-care.

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.

Role of myosin V in actin cable organization in fission yeast

Functional specialization is tightly linked to the ability of eukaryotic cells to acquire a particular shape. Cell morphogenesis, in turn, relies on the capacity to establish and maintain cell "polarity", which is achieved by orienting the trafficking of signaling molecules and organelles towards specific cellular locations and/or membrane domains. The "oriented" transport is based upon cytoskeletal polymers, microtubules and actin filaments, which serve as tracks for molecular motors. These latter generate motion that is translated either into pulling forces or directed transport. Fission yeast, a rod-like unicellular eukaryote, shapes itself by restricting growth at cell tips through the concerted activity of microtubules and actin cables. Microtubules, which assemble into 2-6 bundles and run parallel to the long axis of the cell, serve to orient growth to the tips. Growth is supported by the actin cytoskeleton, which provides tracks, the cables, for motor-based transport of secretory vesicles. The molecular motors, which bind cargos and deliver them to the tips along cables, are also known as type V myosins (hereafter indicated as myosin V). How the bundles of parallel actin filaments, i.e. the cables, extend from the tips through the cell and whether they serve any other purpose, besides providing tracks, is poorly understood. It is also unclear how the crosstalk between the two cytoskeletal systems is achieved. These are the basic questions I addressed during my PhD. The first part of the thesis work (Chapter two) suggests that the sole function of actin cables in polarized growth is to serve as tracks for motors. The data indicate that cells may have evolved two cytoskeletal systems to provide robustness to the polarization process but in principle a unique cytoskeleton might have been able to direct and support polarized growth. How actin cables are organized within the cell to optimize cargo transport is addressed later on (Chapter three). The major finding, based on the actin cable defect of cells lacking myosin Vs, is that actin filaments self-organize through the activity of the transport motors. In fact, by delivering cargos to cell tips and exerting physical pulling forces on actin filaments, Myosin Vs contribute not only to polarize cargo transport but also actin tracks. Among the cargos transported by Myosin V, which may be relevant to its function in organizing cables, there is likely the endoplasmic reticulum (ER). Actin cables, which run parallel to cortical ER, may serve as tracks for Myosin V. Myosin V-driven displacement, in turn, may account for the dynamic expansion and organization of ER during polarized growth as suggested in Chapter four. The last part of the work (Chapter five) highlights the existence of a crosstalk between actin and microtubules. In absence of myosin V, indeed, microtubules contribute to actin cable organization, likely playing a scaffolding/tethering function. Whether or not the kinesin 1, Klp3, plays any role in such process has to be demonstrated. In conclusion the work proposes a novel role for myosin Vs in actin organization, besides its transport function, and provides molecular tools to further dissect the role of this type of myosin in fission yeast. - La spécialisation fonctionnelle est étroitement connectée à la capacité des cellules eucaryotes d'acquérir une forme particulière. La morphogenèse cellulaire à son tour, est basée sur la capacité d'établir et de maintenir la polarité cellulaire, polarité réalisée en orientant le trafic des molécules signales et des organelles vers des zones cellulaires spécifiques. Ce transport directionnel dépend des polymères du cytosquelette, microtubules et microfilaments, qui servent comme des voies pour les moteurs moléculaires. Ces derniers engendrent du mouvement, traduit soit en force de traction soit en transport directionnel. La levure fissipare, un eucaryote unicellulaire en forme de bâtonnet, acquière sa forme en limitant sa croissance aux extrémités par l'action concertée des microtubules et de l'actine. Les microtubules, qui s'assemblent de façon antiparallèle et parcourent la cellule parallèlement à l'axe longitudinal, servent à orienter la croissance aux extrémités. Cette croissance est permise par le cytosquelette d'actine, fournissant des voies, les câbles, pour le transport actif des vésicules de sécrétion. Les moteurs moléculaires, responsables de ce transport actif sont aussi appelés myosines de type V (par la suite appelés myosines V). La manière dont ces câbles s'étendent depuis l'extrémité jusqu'à l'intérieur de la cellule est peu connue. De plus, on ignore également si ces câbles présentent une fonction autre que le transport. L'interaction entre les deux cytosquelettes est également obscure. Ce sont ces questions de base auxquelles j'ai tenté de répondre lors de ma thèse. La première partie de cette thèse (chapitre II) suggère que les câbles d'actine, pendant la croissance polarisée, fonctionnent uniquement comme des voies pour les moteurs moléculaires. Les données indiqueraient que les cellules ont fait évoluer deux systèmes de cytosquelette pour assurer plus de robustesse au processus de polarisation, bien que, comme nous le verrons, un système unique est suffisant. Au chapitre III, nous verrons comment les câbles d'actine sont organisés à l'intérieur de la cellule afin d'optimiser le transport des cargo. La découverte majeure, réalisée en observant des cellules dont la myosine V fait défaut, est que ces filaments d'actine s'auto organisent grâce au passage des moteurs moléculaires le long de ces voies. En réalité, en délivrant les cargos aux extrémités de la cellule et en exerçant des forces de traction sur les câbles, les myosines V contribuent non seulement à polariser le transport mais également à polariser les voies elles mêmes. Nous verrons également au chapitre IV, que parmi les cargos importants pour l'organisation des câbles, il y aurait le réticulum endoplasmique (RE). En effet, les câbles d'actine, qui s'étalent parallèlement au RE cortical, pourraient servir comme voie pour la myosine V. Cette dernière en retour pourrait être responsable de l'expansion dynamique et de l'organisation du RE pendant la croissance polarisée.

Self-Care, Sense Of Coherence And Depression In Patients Hospitalized For Decompensated Heart Failure

OBJECTIVE To analyze the self-care behaviors according to gender, the symptoms of depression and sense of coherence and compare the measurements of depression and sense of coherence according to gender. METHOD A correlational, cross-sectional study that investigated 132 patients with decompensated heart failure (HF). Data were collected through interviews and consultation to medical records, and analyzed using the chi-square and the Student's t tests with significance level of 0.05. Participants were 75 men and 57 women, aged 63.2 years on average (SD = 13.8). RESULTS No differences in self-care behavior by gender were found, except for rest after physical activity (p = 0.017). Patients who practiced physical activity showed fewer symptoms of depression (p<0.001). There were no differences in sense of coherence according to self-care behavior and gender. Women had more symptoms of depression than men (p = 0.002). CONCLUSION Special attention should be given to women with HF considering self-care and depressive symptoms.

Prevalence of self-reported constipation in adults from the general population

OBJECTIVE To estimate the prevalence of self-reported constipation and associated factors in the general population of a Brazilian city. METHOD Secondary analysis of an epidemiological study, population-based, cross-sectional study, about bowel habits of Brazilian population. A total of 2,162 individuals were interviewed using two instruments: sociodemographic data and the adapted and validated Brazilian version of the "Bowel Function in the Community" tool. RESULTS There was a prevalence of 25.2% for the self-reported constipation, 37.2% among women and 10.2% among men. Stroke and old age were associated with constipation in the three statistical models used. CONCLUSION The prevalence found showed to be similar to the findings in the literature, although some associated factors obtained here have never been investigated.

Relationship between the users' contact time in educational programs on diabetes mellitus and self-care skills and knowledge

Abstract OBJECTIVE Check the relationship between the users' contact time in educational programs and self-care and knowledge variables in diabetes mellitus. METHOD A longitudinal study with a quantitative approach with the participation, in the initial phase, of 263 users linked to Basic Health Units in Belo Horizonte, Brazil during the years 2012 and 2013. The data were collected with respect to the total contact time of the users' participation in the educational program as regards knowledge and self-care in acquired diabetes mellitus. The data were analyzed using the Student t-test for comparison of means, considering a 0.05 significance level. RESULTS The final sample included 151 users. The analysis showed that the improvement in self-care scores was statistically higher during an educational intervention of eight hours or more (p-value <0.05). In relation to the scores for knowledge, there was a statistically significant improvement at the end of the educational program. It was not possible to identify a value for the contact time from which there was an increase in mean scores for the ability of knowledge. CONCLUSION To improve the effectiveness of the promotion of skills related to knowledge and self-care in diabetes mellitus, it is necessary to consider the contact time as a relevant factor of the educational program.

Self-serving biases: Evidence from a simulated labor relationship

Previous studies have found evidence of a self-serving bias in bargaining and dispute resolution. We use experimental data to test for this effect in a simulated labor relatonship. We finda consistent discrepancy between employer beliefs and employee actions that can only be attributed to self-serving biases. This discrepancy is evident through stated beliefs, revealed satisfaction, and actual actions. We present evidenceand discuss implications.

From severance pay to self-insurance: Effects of severance payments savings accounts in Colombia

In 1990 Colombia replaced its traditional system of severance paymentswith a new system of severance payments savings accounts (SPSAs). Althoughseverance payments often are justified on the grounds that they provideinsurance against earnings loss, they also increase costs for employersand distort employment decisions. The impact of severance payments dependslargely on how much of the costs to employers can be shifted to workers.The theoretical analysis in this paper shows that, in contrast to atraditional system of severance payments, the system of SPSAs facilitatesthe shifting of severance payments costs to workers in the form of lowerwages. Empirical results using the Colombian National Household Surveysindicate that the introduction of SPSAs shifted around 80% of the totalseverance payments contributions to wages and had a positive effect onweekly hours. Results using the 1997 Colombian Living Standards MeasurementSurvey suggest that, although SPSAs in part replaced employer insurancewith self-insurance, SPSAs continue to play a consumption smoothing rolefor the non-employed.

Ratio maps and correspondence analysis

We compare two methods for visualising contingency tables and developa method called the ratio map which combines the good properties of both.The first is a biplot based on the logratio approach to compositional dataanalysis. This approach is founded on the principle of subcompositionalcoherence, which assures that results are invariant to considering subsetsof the composition. The second approach, correspondence analysis, isbased on the chi-square approach to contingency table analysis. Acornerstone of correspondence analysis is the principle of distributionalequivalence, which assures invariance in the results when rows or columnswith identical conditional proportions are merged. Both methods may bedescribed as singular value decompositions of appropriately transformedmatrices. Correspondence analysis includes a weighting of the rows andcolumns proportional to the margins of the table. If this idea of row andcolumn weights is introduced into the logratio biplot, we obtain a methodwhich obeys both principles of subcompositional coherence and distributionalequivalence.

Regions of rationality: Maps for bounded agents

An important problem in descriptive and prescriptive research in decision making is to identify regions of rationality, i.e., the areas for which heuristics are and are not effective. To map the contours of such regions, we derive probabilities that heuristics identify the best of m alternatives (m > 2) characterized by k attributes or cues (k > 1). The heuristics include a single variable (lexicographic), variations of elimination-by-aspects, equal weighting, hybrids of the preceding, and models exploiting dominance. We use twenty simulated and four empirical datasets for illustration. We further provide an overview by regressing heuristic performance on factors characterizing environments. Overall, sensible heuristics generally yield similar choices in many environments. However, selection of the appropriate heuristic can be important in some regions (e.g., if there is low inter-correlation among attributes/cues). Since our work assumes a hit or miss decision criterion, we conclude by outlining extensions for exploring the effects of different loss functions.

One person in the battlefield is not a warrior: Self-construal, perceived ability to make a difference, and socially responsible behavior

We suggest that cultivating an individual's connectedness to others promotes sociallyresponsible behavior both directly and indirectly through increased perceived abilityto make a difference. Individuals whose interdependent self is more prominent feel theyhave more of an impact on larger scale societal outcomes and, therefore, engage more insocially responsible behaviors than do individuals whose independent self is moreprominent. We test these hypotheses in two experiments in which participants makefinancial contributions or exert an effort for a social cause. In a survey, we find thatperceived effectiveness mediates the effect of self-construal on socially responsibleconsumption.

Are self-regarding subjects more rational?

Through an experiment, we investigate how the level of rationality relatesto concerns for equality and efficiency. Subjects perform dictator games anda guessing game. More rational subjects are not more frequently of the selfregardingtype. When performing a comparison within the same degree of rationality,self-regarding subjects show more strategic sophistication than othersubjects.
