Antsietate asaldura orokorraren tratamenduaren hausnarketa eta erizaintzaren esku hartzea : berrikuspen bibliografikoa

Antsietate asaldurak gaixotasun mentalen artean ugarienak dira; hau horrela izanik, Antsietate Asaldura Orokorraren tratamenduak aztertu beharrekoak dira gaur egun. Lehenik eta behin, ikerketa askoren arabera dependentzia, tolerantzia eta bigarren mailako efektu asko ematen baitira epe luzeko antsietatearen aurkako farmakoetan. Bentzodiazepinak eragiten dituzten arazoak direla eta, garrantzitsua da tratamendu psikologikoaren eraginkortasuna aztertzea. Helburua: Tratamendu farmakologiko eta ez-farmakologikoaren eraginkortasunaren hausnarketa egitea eta patologiaren kudeaketan Erizaintzaren funtzioa baloratzea dira. Metodologia: Scopus, Pubmed, Cochrane library, Trip database, Science Direct, Ministerio de Sanidad Servicios Sociales e Igualdad eta Cuiden bezalako datu baseetan azkeneko 10 urteetako bilaketa bibliografikoaz gain, eskuzko bilaketa ere gauzatu da gaztelaniaz zein ingelesez . Emaitzak: Nahiz eta gidek bentzodiazepinen epe laburrerako erabilpena gomendatu, epe luzerako tratamendu moduan erabiltzen dira bigarren mailako efektu ugari eta dependentzia garatuz. Psikoterapiaren eraginkortasuna, farmakoena baino geldoagoa izaten da baina epe luzera iraupen luzeagoa du. Ondorioak: Bentzodiazepinen eraginkortasuna epe laburrean ezin da ukatu, Terapia Kognitibo-Konduktuala hasteko momentuan erabilgarria izanik bere eraginkortasun sintomatologikoagatik. Erizainaren funtzioa baliagarria da asaldura mental honen balorazioan, beharrezko tratamenduak jasotzea ahalbidetuz eta bideraketa on bat eginez.

Terapias cognitivo-conductuales en la fobia social, en adultos

La fobia social es una enfermedad psiquiátrica que causa costes socioeconómicos significativos y que presenta una alta comorbilidad. Las terapias cognitivo-conductuales (TCC) pueden ser una alternativa de tratamiento efectiva, ya que buscan el cambio de pensamientos y comportamientos adquiridos en una enfermedad con un alto componente de aprendizaje. Objetivo: Verificar la efectividad de las terapias cognitivo-conductuales (TCC) con respecto a otros tratamientos empleados en la fobia social, en adultos (farmacoterapia y otras técnicas de psicoterapia). Metodología: Revisión bibliográfica de estudios de los últimos 10 años, en bases de datos (Pumed etc...). Se seleccionan 12 artículos, 10 ensayos clínicos y 2 meta-análisis. Resultados: Los estudios muestran una respuesta positiva de los pacientes (en términos de reducción de síntomas según escalas de medida estandarizadas para la fobia social) al tratamiento con terapias cognitivo-conductuales (TCC), en sus distintas modalidades de aplicación (individual, grupal y por internet). Estos ratios de respuesta son similares a los que se obtienen en otros tratamientos (farmacoterapia y terapia psicodinámica). Las TCC presentan como ventaja la ausencia de efectos secundarios; como desventaja, su efecto se produce a más largo plazo Conclusiones: No hay resultados concluyentes en relación al beneficio de estas terapias respecto de otras; los factores que determinan fundamentalmente el éxito de las mismas son la situación y la predisposición individual de cada paciente. Dadas las implicaciones de esta patología en la sociedad actual, sería conveniente invertir más medios en el desarrollo de nuevas técnicas.

Efficacy of a cognitive and behavioural psychotherapy applied by primary care psychologists in patients with mixed anxiety-depressive disorder: a research protocol

Background: In contrast with the recommendations of clinical practice guidelines, the most common treatment for anxiety and depressive disorders in primary care is pharmacological. The aim of this study is to assess the efficacy of a cognitive-behavioural psychological intervention, delivered by primary care psychologists in patients with mixed anxiety-depressive disorder compared to usual care. Methods/Design: This is an open-label, multicentre, randomized, and controlled study with two parallel groups. A random sample of 246 patients will be recruited with mild-to-moderate mixed anxiety-depressive disorder, from the target population on the lists of 41 primary care doctors. Patients will be randomly assigned to the intervention group, who will receive standardised cognitive-behavioural therapy delivered by psychologists together with usual care, or to a control group, who will receive usual care alone. The cognitive-behavioural therapy intervention is composed of eight individual 60-minute face-to face sessions conducted in eight consecutive weeks. A follow-up session will be conducted over the telephone, for reinforcement or referral as appropriate, 6 months after the intervention, as required. The primary outcome variable will be the change in scores on the Short Form-36 General Health Survey. We will also measure the change in the frequency and intensity of anxiety symptoms (State-Trait Anxiety Inventory) and depression (Beck Depression Inventory) at baseline, and 3, 6 and 12 months later. Additionally, we will collect information on the use of drugs and health care services. Discussion: The aim of this study is to assess the efficacy of a primary care-based cognitive-behavioural psychological intervention in patients with mixed anxiety-depressive disorder. The international scientific evidence has demonstrated the need for psychologists in primary care. However, given the differences between health policies and health services, it is important to test the effect of these psychological interventions in our geographical setting.

Increased opioid dependence in a mouse model of panic disorder

[EN] Panic disorder is a highly prevalent neuropsychiatric disorder that shows co-occurrence with substance abuse. Here, we demonstrate that TrkC, the high-affinity receptor for neurotrophin-3, is a key molecule involved in panic disorder and opiate dependence, using a transgenic mouse model (TgNTRK3). Constitutive TrkC overexpression in TgNTRK3 mice dramatically alters spontaneous firing rates of locus coeruleus (LC) neurons and the response of the noradrenergic system to chronic opiate exposure, possibly related to the altered regulation of neurotrophic peptides observed. Notably, TgNTRK3 LC neurons showed an increased firing rate in saline-treated conditions and profound abnormalities in their response to met5-enkephalin. Behaviorally, chronic morphine administration induced a significantly increased withdrawal syndrome in TgNTRK3 mice. In conclusion, we show here that the NT-3/TrkC system is an important regulator of neuronal firing in LC and could contribute to the adaptations of the noradrenergic system in response to chronic opiate exposure. Moreover, our results indicate that TrkC is involved in the molecular and cellular changes in noradrenergic neurons underlying both panic attacks and opiate dependence and support a functional endogenous opioid deficit in panic disorder patients.

Mindfulness training for reducing anger, anxiety, and depression in fibromyalgia patients

Fibromyalgia is a disabling syndrome. Results obtained with different therapies are very limited to date.The goal of this study was to verify whether the application of a mindfulnessbased training program was effective in modifying anger, anxiety, and depression levels in a group of women diagnosed with fibromyalgia. This study is an experimental trial that employed a waiting list control group. Measures were taken at three different times: pretest, posttest, and follow-up. The statistical analyses revealed a significant reduction of anger (trait) levels, internal expression of anger, state anxiety, and depression in the experimental group as compared to the control group, as well as a significant increase in internal control of anger. It can be concluded that the mindfulness-based treatment was effective after 7 weeks. These results were maintained 3 months after the end of the intervention.

Bipolar disorder comorbid with alcohol use disorder: Focus on neurocognitive correlates

Bipolar disorder (BD) and alcohol use disorders (AUDs) are usually comorbid, and both have been associated with significant neurocognitive impairment. Patients with the BD-AUD comorbidity (dual diagnosis) may have more severe neurocognitive deficits than those with a single diagnosis, but there is paucity of research in this area. To explore this hypothesis more thoroughly, we carried out a systematic literature review through January 2015. Eight studies have examined the effect of AUDs on the neurocognitive functioning of BD patients. Most studies found that BD patients with current or past history of comorbid AUDs show more severe impairments, especially in verbal memory and executive cognition, than their non-dual counterparts. Greater neurocognitive dysfunction is another facet of this severe comorbid presentation. Implications for clinical practice and research are discussed. Specifically, the application of holistic approaches, such as clinical staging and systems biology, may open new avenues of discoveries related to the BD-AUD comorbidity.

Response of the topological surface state to surface disorder in TlBiSe2

Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile Tl atoms at room temperature. No trivial surface states are observed in photoemission at low temperatures, which suggests that these islands cannot be regarded as a clear surface termination. The topological surface state is, however, clearly resolved in photoemission experiments. This is interpreted as direct evidence of its topological self-protection and shows the robust nature of the Dirac cone-like surface state. Our results can also help explain the apparent mass acquisition in S-doped TlBiSe2.
