Proceso experiencial y su relación con la libertad desde el enfoque Humanista- Existencial : un estudio de caso de una paciente con rasgos del trastorno de personalidad por dependencia (TPD)

El objetivo del presente estudio de caso tiene como fin, comprender el proceso experiencial de una paciente de 21 años, quien presenta rasgos de Dependencia Emocional, lo anterior basándonos desde un enfoque Humanista Existencial. Dicho estudio permite comprender la manera en que la paciente configura su mundo, utiliza su libertad, decide utilizar sus mecanismos de defensa, basada en la comprensión de sus deseos, su intencionalidad y la manera en que actúa acorde esto, proyectándose de manera intencional en su presente continuo. Como resultado de este análisis, se observó que la paciente utiliza mecanismo de defensa tales como víctima inocente, desplazamiento de la responsabilidad, buscando de manera constante un salvador, entre otros, con el fin de seguir aferrada a ese vínculo con su pareja y no asumir su libertad de manera responsable, comprendiendo y asumiendo el papel protagónico que tiene en su vida. Así mismo, se observó el impacto que tienen las redes sociales en las personas que presentan TPD, por otro lado, se analizó y resalto la importancia de trabajar los límites durante psicoterapia, permitiendo que este comprenda sus propios deseos, y a partir de eso, actuar, conociendo sus emociones, sentimientos, gustos, basándose primero en su mundo que en el de la otra persona.MaestríaMagister en Psicologí

Electrical impedance tomography to evaluate air distribution prior to extubation in very-low-birth-weight infants: a feasibility study

OBJECTIVES: Nasal continuous positive airway pressure is used as a standard of care after extubation in very-low-birth-weight infants. A pressure of 5 cmH2O is usually applied regardless of individual differences in lung compliance. Current methods for evaluation of lung compliance and air distribution in the lungs are thus imprecise for preterm infants. This study used electrical impedance tomography to determine the feasibility of evaluating the positive end-expiratory pressure level associated with a more homogeneous air distribution within the lungs before extubation. METHODS: Ventilation homogeneity was defined by electrical impedance tomography as the ratio of ventilation between dependent and non-dependent lung areas. The best ventilation homogeneity was achieved when this ratio was equal to 1. Just before extubation, decremental expiratory pressure levels were applied (8, 7, 6 and 5 cmH(2)0; 3 minutes each step), and the pressure that determined the best ventilation homogeneity was defined as the best positive end-expiratory pressure. RESULTS: The best positive end-expiratory pressure value was 6.3 ± 1.1 cmH(2)0, and the mean continuous positive airway pressure applied after extubation was 5.2 ± 0.4 cmH(2)0 (p = 0.002). The extubation failure rate was 21.4%. X-Ray and blood gases after extubation were also checked. CONCLUSION: This study demonstrates that electrical impedance tomography can be safely and successfully used in patients ready for extubation to suggest the best ventilation homogeneity, which is influenced by the level of expiratory pressure applied. In this feasibility study, the best lung compliance was found with pressure levels higher than the continuous positive airway pressure levels that are usually applied for routine extubation

Trust and control interrelations: New perspectives on the trust control nexus

This article is the post-print version of the published article that may be accessed at the link below. Copyright @ 2007 Sage Publications.This article introduces the special issue on New Perspectives on the Trust-Control Nexus in Organizational Relations. Trust and control are interlinked processes commonly seen as key to reach effectiveness in inter- and intraorganizational relations. The relation between trust and control is, however, a complex one, and research into this relation has given rise to various and contradictory interpretations of how trust and control relate. A well-known discussion is directed at whether trust and control are better conceived as substitutes, or as complementary mechanisms of governance. The articles in this special issue bring the discussion on the relationship between both concepts a step further by identifying common factors, distinctive mechanisms, and key implications relevant for theory building and empirical research. By studying trust and control through different perspectives and at different levels of analysis, the articles provide new theoretical insights and empirical evidence on the foundations of the trust-control interrelations

Casimir Effect, Achucarro-Ortiz Black Hole and the Cosmological Constant

We treat the two-dimensional Achucarro-Ortiz black hole (also known as (1+1) dilatonic black hole) as a Casimir-type system. The stress tensor of a massless scalar field satisfying Dirichlet boundary conditions on two one-dimensional "walls" ("Dirichlet walls") is explicitly calculated in three different vacua. Without employing known regularization techniques, the expression in each vacuum for the stress tensor is reached by using the Wald's axioms. Finally, within this asymptotically non-flat gravitational background, it is shown that the equilibrium of the configurations, obtained by setting Casimir force to zero, is controlled by the cosmological constant.Comment: 20 pages, LaTeX, minor corrections, comments and clarifications added, version to appear in Phys.

Balneotherapy is a potential risk factor for Pseudomonas aeruginosa colonization

The practice of immersion in burn patient has been abandoned in many parts of the world but in Brazil it is still common. The aim of this study was to ascertain if balneotherapy is a risk factor for Pseudomonas aeruginosa colonization in thermally injured patients. Eighteen patients from a Burn Center were studied for 14 weeks for Pseudomonas aeruginosa. Samples were collected by swabbing the exudate of wounds, before and after giving bath to the patients and from balneotherapy table. Pulsed-field gel electrophoresis was used to determine bacterial genetic relatedness. Thirty-seven P. aeruginosa isolates were detected from 292 swabs collected from patients' burn surface area and from the balneotherapy table. Profile analysis of P. aeruginosa DNA fragmentation showed 10 clones among the 37 strains analyzed. Type A is the most prevalent clone, with 23 strains distributed into eight subtypes. These were present in the swabs collected, before and after the patients' bath, from the surface of the bath table, suggesting that there was cross-contamination between the patients in different ways. This work demonstrates that balneotherapy is a risk factor in the Burn Center studied, because the same clone was found among P. aeruginosa isolates collected at various points and times.A prática de balneotarapia em paciente queimado foi abandonada em muitas partes do mundo, mas no Brasil ainda é comum. O objetivo deste estudo foi verificar se a balneoterapia é um fator de risco para a colonização por Pseudomonas aeruginosa em pacientes queimados. Dezoito pacientes internados em um Centro de Queimadura (CQ) foram acompanhados por 14 semanas. Amostras foram coletadas do exsudato de feridas, antes e depois do banho dos pacientes e também da mesa onde a balneoterapia foi realizada. A relação genética entre as cepas de P. aeruginosa foi determinada pela electroforese em gel de campo pulsado. Trinta e sete cepas foram detectadas a partir de 292 swabs coletados de área de superfície das feridas dos pacientes e da mesa de balneoterapia. Análise de fragmentação do DNA das 37 P. aeruginosa mostrou a existência de 10 clones. O tipo A foi o clone mais prevalente, com 23 cepas distribuídas em oito subtipos. Estas estavam presentes nas lesões dos pacientes antes e após o banho e na mesa onde o banho foi realizado, sugerindo contaminação cruzada inter e intra-pacientes e pacientes e mesa de banho. Este trabalho mostra que a balneoterapia é um fator de risco para colonização por P. aeruginosa, no CQ estudado, pois um mesmo clone da bactéria foi encontrado nos isolados coletados em vários pontos e épocas diferentes

Anal Examinations in Cases of Alleged Homosexuality

Anal examinations are forcibly conducted in many countries where consensual anal intercourse is considered a criminal act. They are conducted almost exclusively on males in an effort to “prove” that they are “homosexuals” despite the fact that anal intercourse is not a necessary determinant of “homosexual activity.” Forcibly conducted anal examinations are usually initiated at the request of law enforcement officials, the prosecutor, or the court and conducted in the absence of informed consent or in circumstances where individuals are not capable of giving genuine informed consent or where refusal to give consent would be interpreted as self-incrimination. This may be presumed to be the case when examinations are conducted on individuals in detention, subsequent to allegations of criminalised sexual acts by the authorities. The purpose of this medico-legal statement is to provide legal experts, adjudicators, health care professionals, and policymakers, among others, with an understanding of: 1) the validity of forcibly conducted anal examinations as medical and scientific evidence of consensual anal intercourse; 2) the likely physical and psychological consequences of forcibly conducted anal examinations; and 3) whether, based on these effects, forcibly conducted anal examination constitutes cruel, inhuman, or degrading treatment or torture
