Perceived coercion to enter treatment among involuntarily and voluntarily admitted patients with substance use disorders
2016
Background Perceived coercion is a sense of pressure related to the experience of being referred to treatment. The sense of pressure arises from the patient’s internal perception of coercion. The sources of coercion may be the legal system, the family, the health system, or self-criticism (internal sources). Here, we studied patients diagnosed with substance use disorders that were involuntarily admitted to hospital, pursuant to a social services act. We sought to determine whether these patients perceived coercion differently than patients that were admitted voluntarily. Methods This study included patients admitted to combined substance use disorder and psychiatry wards in three publicly …
What happens when we get angry? Hormonal, cardiovascular and asymmetrical brain responses
2010
This study aimed to evaluate neuroendocrine and cardiovascular responses together with changes in brain asymmetry following an anger mood induction laboratory task. Previous research has shown an increase in heart rate and blood pressure when anger is experienced. Increased testosterone and decreased cortisol in response to anger and aggressive behavior have also been reported. With regard to asymmetrical frontal brain activity and emotion, the valence model links negative affect (as anger) to the right hemisphere while the motivational direction model links approach-related emotions (as anger) to the left hemisphere. From the subjective perception and from the neuroendocrine and cardiovasc…
Wave similarity mapping shows the spatiotemporal distribution of fibrillatory wave complexity in the human right atrium during paroxysmal and chronic…
2005
Introduction: The complexity of waveforms during atrial fibrillation may reflect critical activation patterns for the arrhythmia perpetuation. In this study, we introduce a novel concept of map, based on the analysis of the wave morphology, which gives a direct evidence in the human right atrium on the spatiotemporal distribution of fibrillatory wave complexity in paroxysmal (PAF) and chronic (CAF) atrial fibrillation. Methods and Results: Electrograms were recorded from a 64-electrode catheter in the right atrium of 15 patients during PAF (n = 8) and CAF (n = 7). Wave similarity maps were constructed by calculating the degree of morphological similarity of activation waves (S) at each atri…
Psychopathological and emotional deficits in myotonic dystrophy
1998
OBJECTIVE—To evaluate psychopathological disturbances in patients with myotonic dystrophy (MD) and compare patients with MD to both patients with facioscapulohumeral dystrophy (FSHD) and healthy control subjects. METHODS—A semistructured interview was used to determine DSM III-R criteria for major depressive episodes, dysthymic episodes, and generalised anxiety. The Montgomery and Asberg and the Hamilton depressive scales, the Covi and Tyrer anxiety scales, the Abrams and Taylor scale for emotional blunting, and the depressive mood scale were all used in the study. Subjects were also asked to complete questionnaires for physical and social anhedonia. RESULTS—Fifteen patients with MD, 11 pat…
Countertransference in Factitious Disorder
1994
In the treatment of patients with factitious disorder it is important to realize that at various levels of their experience these patients are more intimate with death than with life. This requires a particular awareness of resistance mechanisms to countertransference as well as of the importance of clinical procedures, in particular with regard to superego analysis. A requirement for establishing a psychotherapeutic alliance with patients suffering from factitious disorder is a high degree of 'therapeutic eros', hope and trust in one's own capabilities. The emphasis on a 'biophile attitude' does, however, involve the danger that the destructive potential, fantasies of death or killing, but…
Predictive signs and indicators of aggressiveness and violence: a comparison between a group of adolescents attending an external penal area, a group…
2006
Aim. We considered the spreading and the increasing of aggressive and violent behaviours. The most of them have two common roots: lack of actual motivation and brutality. Our research intends to detect specific indicators and predictive signs of violent and aggressive behaviours. In order to this, scientific literature shows that the most reliable indicators and predictive signs are linked to structural personality features (e.g. defensive strategies, impulse control). Methods. This cross sectional study compares a group of 26 male adolescents with Conduct Disorder (F91.8), a group of 29 male patients with Borderline Personality Disorder (F60.31) and a group of 33 male prisoners with Antiso…
Differential Response of Ant Colonies to Intruders: Attack Strategies Correlate With Potential Threat
2011
Animals are often threatened by predators, parasites, or competitors, and attacks against these enemies are a common response, which can help to remove the danger. The costs of defense are complex and involve the risk of injury, the loss of energy ⁄time, and the erroneous identification of a friend as a foe. Our goal was to study the specificity of defense strategies. We analyzed the aggressive responses of ant colonies by confronting them with workers of an unfamiliar congeneric species, a non-nestmate conspecific, a co-occurring congeneric competitor species, and a social parasite—a slave-making ant. As expected, the latter species, which can inflict dramatic fitness losses to the colony,…
Age-dependent inbreeding risk and offspring fitness costs in female black grouse
2011
Dispersal is an important mechanism used to avoid inbreeding. However, dispersal may only be effective for part of an individual's lifespan since, post-dispersal individuals that breed over multiple reproductive events may risk mating with kin of the philopatric sex as they age. We tested this hypothesis in black grouse Tetrao tetrix , and show that yearling females never mated with close relatives whereas older females did. However, matings were not with direct kin suggesting that short-distance dispersal to sites containing kin and subsequent overlap of reproductive lifespans between males and females were causing this pattern. Chick mass was lower when kinship was high, suggesting impor…
Intramuscular sex steroid hormones are associated with skeletal muscle strength and power in women with different hormonal status
2015
International audience; Estrogen (E2)-responsive peripheral tissues, such as skeletal muscle, may suffer from hormone deficiency after menopause potentially contributing to the aging of muscle. However, recently E2 was shown to be synthesized by muscle and its systemic and intramuscular hormone levels are unequal. The objective of the study was to examine the association between intramuscular steroid hormones and muscle characteristics in premenopausal women (n = 8) and in postmenopausal monozygotic twin sister pairs (n = 16 co-twins from eight pairs) discordant for the use of E2-based hormone replacement. Isometric skeletal muscle strength was assessed by measuring knee extension strength.…
Manejo de la hiperglucemia con fármacos no insulínicos en pacientes adultos con diabetes tipo 2
2019
Resumen: El adecuado tratamiento de la diabetes mellitus tipo 2 (DM2) incluye la alimentación saludable y el ejercicio (150 min/semana) como pilares básicos. Para el tratamiento farmacológico, la metformina es el fármaco de elección inicial, salvo contraindicación o intolerancia; en caso de mal control, se dispone de 8 familias terapéuticas (6 orales y 2 inyectables) como posibles combinaciones. Se presenta un algoritmo y unas recomendaciones para el tratamiento de la DM2. En prevención secundaria cardiovascular se recomienda asociar un inhibidor del cotransportador sodio-glucosa tipo 2 (iSGLT2) o un agonista del receptor de glucagon-like peptide-1 (arGLP1) en pacientes con obesidad. En pre…
