Our study aimed to assess the quality of life (QoL) of patients with congestive heart failure (CHF) and to correlate the different aspects of QoL with relevant socio-demographic variables, CHF severity, somatic comorbidities, other clinical variables and depressive symptomatology. In a cross-sectional study design, a community sample of 103 adult patients with CHF (mean age 68 years, 73 % male) was recruited from an outpatient cardiology practice. CHF severity was assessed with physician ratings of the New York Heart Association (NYHA) functional class and measurement of brain natriuretic peptide (BNP) levels. The psychometric evaluation of quality of life was made using the Medical Outcomes Study Short Form-36 (SF-36) and the Kansas City Cardiomyopathy Questionnaire (KCCQ). The Beck Depression Inventory Second Edition (BDI-II) assessed depressive symptoms. Using multiple linear regression, predictors of poorer QoL included being a female, being older, living alone, NYHA functional class ≥ II, higher levels of BNP comorbidity (such as renal insufficiency and cerebrovascular disease), fluid retention, depressive symptomatology (assessed by BDI-II) and treatment with anti-dyslipidemics, diuretics and β-blockers. Among these correlates, psychological distress was the most strongly related to QoL. Also, functional status measured by NYHA demonstrated a high impact on QoL. Our findings suggest the need to address such factors in developing effective care to improve psychological and functional status in order to enhance QoL in these patients.  相似文献

The phenomenon of cheating in higher education is of overwhelming importance in that the students engaging in these acts are unlikely to have the skills necessary for their future professional life. Despite its relevance, the empirical evaluation of cheating in universities has been almost exclusively focused on the US context. Little is known about cheating at the European level, let alone in Portugal. Even less is explored at the regional level. In this paper we present evidence on the perception of cheating by Portuguese undergraduate students of economics/business degrees. We undertake a large-scale survey, involving 2675 students from all Portuguese mainland public universities (10). We found that copying-favourable environments are associated with a higher propensity to cheat. Moreover, in universities where ‘codes of honour’ exist, this propensity tends to be lower. Finally, the propensity to copy seems to be highly influenced by the cultural systems and socially-related factors of different regions.  相似文献

Our paper offers a reflection on the state of the art of antisocial behaviors in adolescence, seeking to review and synthesize relevant conclusions from developmental investigation on this subject. We begin by identifying the peculiarities of the antisocial phenomenon in adolescence, with particular focus on social and family aspects that may influence social behaviors at this stage, as well as on individual variables that undergo considerable development in adolescence and may play an important role in risk behaviors, such as psychosocial competence, personality, self-concept, and intelligence. The general conclusion points out questions that remain unanswered. Therefore, work seeking to address some of those questions is presented.  相似文献

The paradigmatic theory of modern epistemology holds psychoanalysis in its scientific statute. Even if there is no explicit epistemology in the Freudian writings, it is undeniable that the genesis of psychoanalysis has a rigorous dialetic between theorization and clinical observation. Metapsychology is an organized and consistent set of concepts, capable of explaining and coordinating the analytical experience. It is through metapsychology that clinical work encounters the possibility of universalization, while metapsychology finds the possibility of fulfillment in clinical work. Clinical experience also confirms the interrelation between psychopathology and culture. Modern times have brought about new versions for psychopathological symptoms, which, in turn, have special effects on the narcisistic personalities and the manifestations of anxiety, giving place to different neurotic configurations.  相似文献

The general theory of variable binding term operators is an interesting recent development in logic. It opens up a rich class of semantic and model-theoretic problems. In this paper we survey the recent literature on the topic, and offer some remarks on its significances and on its connections with other branches of mathematical logic.  相似文献

The purpose was three-fold: (1) to investigate the effect of baseline, precompetition, and postcompetition stress on salivary cortisol levels in top-ranking Brazilian wrestlers (N = 17) participating in a national competition; (2) to estimate correlations among three stress measures (perceived stress, salivary cortisol, and physiological stress reaction); and (3) to compare cortisol concentrations between losers and winners. Salivary cortisol was collected at baseline, pre-, and postcompetition. Physiological stress reaction and perceived stress scores were measured just before warm-up for the competition. Analysis showed a significant main effect for testing time. Correlations among the stress measures were not significant. Analysis of covariance between the winners (n = 10) and the losers (n = 7) was also not significant. Salivary cortisol concentrations increased after the intense exercise of competition. The wrestlers did not perceive any physiological effects.  相似文献

Polyamines, such as spermidine and spermine, have been reported to improve memory retention through the activation of N-methyl-d-aspartate receptors (NMDAr). However whether polyamine agonists and antagonists alter extinction remains unclear. In the current study, we investigated whether spermidine and polyamine antagonists that selectively block the NR2B subunit at the NMDAr alter the extinction of contextual conditioned fear in male Wistar rats. The bilateral intra-hippocampal administration of exogenous spermidine (2 nmol/site) immediately after, but not 6 h after extinction training, facilitated the extinction of fear conditioning. The injection of the NMDAr antagonists arcaine (0.2 nmol/site), ifenprodil (20 nmol/site) and traxoprodil (0.2 nmol/site), disrupted fear extinction and, at doses that had no effect per se, reversed the facilitatory effect of spermidine on fear extinction. These results suggest that exogenous and endogenous polyamines facilitate the extinction of contextual conditioned fear through activation of NR2B subunit-containing NMDAr in the hippocampus. Since extinction-based exposure therapy is widely used as treatment for a number of anxiety-related disorders, including phobias and post-traumatic stress, the currently reported facilitation of extinction by polyaminergic agents suggest these compounds as putative candidates for drug development.  相似文献

In the embodied cognition framework, sensory, motor and emotional experiences are encoded along with sensorimotor cues from the context in which information was acquired. As such, representations retain an initial imprint of the manner in which information was acquired. The current study reports results indicating a lack of embodiment effects in ASD and, further, an association between embodiment differences and ASD symptomatology. The current results are consistent with an embodied account of ASD that goes beyond social experiences and could be driven by subtle deficits in sensorimotor coordination.  相似文献

This qualitative study analyzes the definitions of manhood provided by a US sample of 36 adult, working class Latinos who identify as feminist, and have attended institutions of higher education. Using an intersectional framework, we analyze in-depth interviews and address the research questions “To what extent did participants identify with their gender, race, ethnicity, sexuality, and class background? How did participants subjectively define what it means to be a man?”. Results indicate that participants identified with their significant social groups to varying degrees. Manhood was defined in relational, ethical, and counter-hegemonic ways. Our discussion examines the way participants wove in and out of discourses related to hegemonic notions of manhood deemed as positive, while simultaneously rejecting aspects of hegemonic masculinity.  相似文献

This study aimed to compare therapists’ observable behaviors to promote alliances with involuntary and voluntary clients during brief family therapy. The therapists’ contributions to fostering alliances were rated in sessions 1 and 4 using videotapes of 29 families who were observed in brief therapy. Using the System for Observing Family Therapy Alliances, trained raters searched for specific therapist behaviors that contributed to or detracted from the four alliance dimensions: engagement in the therapeutic process, an emotional connection with the therapist, safety within the therapeutic system, and a shared sense of purpose within the family. The results showed that when working with involuntary clients, therapists presented more behaviors to foster the clients’ engagement and to promote a shared sense of purpose within the family. However, in the fourth session, the therapists in both groups contributed to the alliance in similar ways. The results are discussed in terms of (a) the therapists’ alliance‐building behaviors, (b) the specificities of each client group, and (c) the implications for clinical practice, training, and research.  相似文献
