[Ab] Resumo:The view of sexuality Freud first proposed in the Three Essays on the Theory of Sexuality contains a discrepancy between the sexuality perverse and polymorphous described in the first two essays and the biologically directed, reproductive sexuality of the third essay. According to Jean Laplanche, the theorist of psychoanalysis who is Freud's closest reader and translator, the discrepancy is due to two contradictory opinions Freud apparently held at different moments of his writing: one, that sexuality is exogenous, an effect of seduction by adults; two, that sexuality is endogenous, innate in the human biological organism. This article focuses on Laplanche's elucidation of two aspects of sexuality present in each adult: an instinctual, hormonally based, and ultimately reproductive sexual impulse, which begins at puberty, and the drive-based sexual impulses first theorized by Freud as polymorphous-perverse infantile sexuality, which begin in infancy and continue to be active throughout the individual's life. Laplanche's rereading of Freud leads to a more complex understanding of sexuality as always deviant, in one way or another and to a greater or lesser degree, from the established social norms. So-called sexual deviance, therefore, is not a problem within the sexual but an issue within the social field.

[Ti] Título:Imidazoline 1 receptor activation preserves respiratory drive in spontaneously breathing newborn rats during dexmedetomidine administration.

[Ab] Resumo:BACKGROUND: Dexmedetomidine is an alpha-2 (α ) adrenoceptor and imidazoline 1 (I ) receptor agonist that provides sedation without loss of respiratory drive. AIMS: The aim of this study was to elucidate the involvement of α -adrenoceptor and I receptor in the cardiorespiratory changes induced by dexmedetomidine in spontaneously breathing newborn rats. METHODS: An abdominal catheter to administer drugs and three subcutaneous electrodes to record electrocardiographic data were inserted into 2- to 5-day-old Wistar rats under isoflurane anesthesia. In individual chambers, each rat was intraperitoneally administered dexmedetomidine (50 µg·kg ) followed 5 min later by normal saline or 1, 5, or 10 mg·kg atipamezole (selective α -adrenoceptor antagonist) or efaroxan (α -adrenoceptor/I receptor antagonist). Cardiorespiratory indices were recorded before and after drug administration. RESULTS: The administration of dexmedetomidine alone resulted in significant changes to most of the cardiorespiratory indices examined. The addition of 5 or 10 mg·kg atipamezole or 1 mg·kg efaroxan completely ameliorated the dexmedetomidine-associated reduction in heart rate (HR). The addition of 1 mg·kg atipamezole or 1 or 5 mg·kg efaroxan completely ameliorated the dexmedetomidine-associated reduction in respiratory frequency. Mean inspiratory flow (V /T ; V is tidal volume and T is inspiratory time), which is an index of respiratory drive, was not significantly affected by the administration of dexmedetomidine alone (P = 0.273) or dexmedetomidine + atipamezole (P = 0.605, 0.153, 0.138 for 1, 5, 10 mg·kg atipamezole, respectively); however, it was significantly decreased after the administration of dexmedetomidine + efaroxan (P = 0.029, <0.001, <0.001 for 1, 5, 10 mg·kg efaroxan, respectively). CONCLUSIONS: Our results suggest that in newborn rats undergoing dexmedetomidine sedation, the α -adrenoceptor, but not I receptor, is involved in the regulation of HR and respiratory frequency, and that activation of the I receptor plays a major role in the maintenance of respiratory drive.

[Ti] Título:The so-called death drive, an indispensable force for any subjective life.

[Ab] Resumo:The psychoanalytic movement has difficulty in overcoming the malaise bequeathed by what Freud wanted to call the 'death drive'. This term remains doubly problematic: first because the indispensable antagonist of Eros-binding cannot be reduced to a particular drive; and secondly because this Anteros plays a vital role in subjectivization. The Freudian idea of the 'death drive' has in addition the drawback of confusing dissociative thrust (unbinding) with the aggressive component of libidinal cathexis. Now it is precisely the lack of articulation between them that leads to deconstructing it. For it is constantly observed that in the psychic register aggression is much more fixing than unbinding. The essential role of Anteros/unbinding in the process of subjectivization can be illustrated through several key operations in subjective development: sublimatory activity and its renunciation of pleasure-discharge, the work of mourning opposed to melancholic fixation, the intricating-unbinding parental function, and finally the psychoanalytic treatment and its work of analysis. This means we should cease to anathematize the dynamic component of unbinding as 'of death' and seek to explain the concept of subjectivization better.

[Ab] Resumo:Our study examined whether verbally participating in fat talk conversations had a different effect on women's body image perception than merely listening to friends engage in fat talk conversations. Participants were 321 women who completed measures of listening to and participating in fat talk conversations, drive for thinness, body dissatisfaction, and dietary restraint. Results indicated that verbally participating in fat talk was a much stronger predictor of women's drive for thinness, body dissatisfaction, and dietary restraint than merely listening to friends engage in fat talk conversations.

[Ab] Resumo:OBJECTIVE: Fitspiration is a recent Internet trend designed to motivate people to eat healthily and to exercise. The aim of the study was to investigate disordered eating and exercise in women who post fitspiration on Instagram. METHOD: Participants were 101 women who post fitspiration images on Instagram and a comparison group of 102 women who post travel images. Both groups completed measures of disordered eating and compulsive exercise. RESULTS: Women who post fitspiration images scored significantly higher on drive for thinness, bulimia, drive for muscularity, and compulsive exercise. Almost a fifth (17.5%) of these women were at risk for diagnosis of a clinical eating disorder, compared to 4.3% of the travel group. Compulsive exercise was related to disordered eating in both groups, but the relationship was significantly stronger for women who post fitspiration images. DISCUSSION: For some women, posting fitspiration images on Instagram may signify maladaptive eating and exercise behaviors. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2017; 50:76-79).

[Ab] Resumo:Goal-directed social behaviours such as mating and fighting are associated with scalable and persistent internal states of emotion, motivation, arousal or drive. How those internal states are encoded and coupled to behavioural decision making and action selection is not clear. Recent studies in Drosophila melanogaster and mice have identified circuit nodes that have causal roles in the control of innate social behaviours. Remarkably, in both species, these relatively small groups of neurons can influence both aggression and mating, and also play a part in the encoding of internal states that promote these social behaviours. These similarities may be superficial and coincidental, or may reflect conserved or analogous neural circuit modules for the control of social behaviours in flies and mice.

[Ti] Título:Neurophysiological Evidence for a Cortical Contribution to the Wakefulness-Related Drive to Breathe Explaining Hypocapnia-Resistant Ventilation in Humans.

[Ab] Resumo:Spontaneous ventilation in mammals is driven by automatic brainstem networks that generate the respiratory rhythm and increase ventilation in the presence of increased carbon dioxide production. Hypocapnia decreases the drive to breathe and induces apnea. In humans, this occurs during sleep but not during wakefulness. We hypothesized that hypocapnic breathing would be associated with respiratory-related cortical activity similar to that observed during volitional breathing, inspiratory constraints, or in patients with defective automatic breathing (preinspiratory potentials). Nineteen healthy subjects were studied under passive (mechanical ventilation, n = 10) or active (voluntary hyperventilation, n = 9) profound hypocapnia. Ventilatory and electroencephalographic recordings were performed during voluntary sniff maneuvers, normocapnic breathing, hypocapnia, and after return to normocapnia. EEG recordings were analyzed with respect to the ventilatory flow signal to detect preinspiratory potentials in frontocentral electrodes and to construct time-frequency maps. After passive hyperventilation, hypocapnia was associated with apnea in 3 cases and ventilation persisted in 7 cases (3 and 6 after active hyperventilation, respectively). No respiratory-related EEG activity was observed in subjects with hypocapnia-related apneas. In contrast, preinspiratory potentials were present at vertex recording sites in 12 of the remaining 13 subjects (p < 0.001). This was corroborated by time-frequency maps. This study provides direct evidence of a cortical substrate to hypocapnic breathing in awake humans and fuels the notion of corticosubcortical cooperation to preserve human ventilation in a variety of situations. Of note, maintaining ventilatory activity at low carbon dioxide levels is among the prerequisites to speech production insofar as speech often induces hypocapnia. SIGNIFICANCE STATEMENT: Human ventilatory activity persists, during wakefulness, even when hypocapnia makes it unnecessary. This peculiarity of human breathing control is important to speech and speech-breathing insofar as speech induces hypocapnia. This study evidences a specific respiratory-related cortical activity. This suggests that human hypocapnic breathing is driven, at least in part, by cortical mechanisms similar to those involved in volitional breathing, in breathing against mechanical constraints or with weak inspiratory muscle, and in patients with defective medullary breathing pattern generators. This fuels the notion that the human ventilatory drive during wakefulness often results from a corticosubcortical cooperation, and opens new avenues to study certain ventilatory and speech disorders.

[Ab] Resumo:Objectives There remains limited consensus regarding the definition and conceptual basis of exercise addiction. An understanding of the factors motivating maintenance of addictive exercise behavior is important for appropriately targeting intervention. The aims of this study were twofold: first, to establish consensus on features of an exercise addiction using Delphi methodology and second, to identify whether these features are congruous with a conceptual model of exercise addiction adapted from the Work Craving Model. Methods A three-round Delphi process explored the views of participants regarding the features of an exercise addiction. The participants were selected from sport and exercise relevant domains, including physicians, physiotherapists, coaches, trainers, and athletes. Suggestions meeting consensus were considered with regard to the proposed conceptual model. Results and discussion Sixty-three items reached consensus. There was concordance of opinion that exercising excessively is an addiction, and therefore it was appropriate to consider the suggestions in light of the addiction-based conceptual model. Statements reaching consensus were consistent with all three components of the model: learned (negative perfectionism), behavioral (obsessive-compulsive drive), and hedonic (self-worth compensation and reduction of negative affect and withdrawal). Conclusions Delphi methodology allowed consensus to be reached regarding the features of an exercise addiction, and these features were consistent with our hypothesized conceptual model of exercise addiction. This study is the first to have applied Delphi methodology to the exercise addiction field, and therefore introduces a novel approach to exercise addiction research that can be used as a template to stimulate future examination using this technique.

[Ti] Título:The longitudinal relationship between worry and disordered eating: Is worry a precursor or consequence of disordered eating?

[Ab] Resumo:Worry, the core component of generalized anxiety disorder, is associated with disordered eating. However, it is unclear whether worry is a precursor to disordered eating or whether worry is a consequence of disordered eating (or both). The current study tested if worry prospectively predicted disordered eating symptoms and vice-versa across six months. Young adult women (n=300) completed a measure of worry and disordered eating at Time 1, and two months and six months later. A prospective path model utilizing structural equation modeling investigated if worry predicted disordered eating (and vice-versa). Worry prospectively predicted drive for thinness across both two and six months while controlling for previous levels of worry. In the opposite direction, drive for thinness did not predict worry over time. There were no prospective relationships between worry and bulimia or body dissatisfaction. Therefore, interventions focusing on decreasing worry could be effective in preventing and treating excessive concerns about thinness and their associated impairment.
