Medication errors in mental healthcare:a systematic review

Methods: It has been estimated that medication error harms 1-2% of patients admitted to general hospitals. There has been no previous systematic review of the incidence, cause or type of medication error in mental healthcare services. Methods: A systematic literature search for studies that examined the incidence or cause of medication error in one or more stage(s) of the medication-management process in the setting of a community or hospital-based mental healthcare service was undertaken. The results in the context of the design of the study and the denominator used were examined. Results: All studies examined medication management processes, as opposed to outcomes. The reported rate of error was highest in studies that retrospectively examined drug charts, intermediate in those that relied on reporting by pharmacists to identify error and lowest in those that relied on organisational incident reporting systems. Only a few of the errors identified by the studies caused actual harm, mostly because they were detected and remedial action was taken before the patient received the drug. The focus of the research was on inpatients and prescriptions dispensed by mental health pharmacists. Conclusion: Research about medication error in mental healthcare is limited. In particular, very little is known about the incidence of error in non-hospital settings or about the harm caused by it. Evidence is available from other sources that a substantial number of adverse drug events are caused by psychotropic drugs. Some of these are preventable and might probably, therefore, be due to medication error. On the basis of this and features of the organisation of mental healthcare that might predispose to medication error, priorities for future research are suggested.

O antagonismo do receptor de serotonina do tipo 7 da substância cinzenta periaquedutal dorsal reduz a ansiedade experimental basal, mas não aquela gerada pela retirada do etanol em ratos

Ethanol-dependent individuals who reduce or discontinue its use may present Alcohol Withdrawal Syndrome, which is characterized by unpleasant signs and symptoms, such as anxiety, that may trigger relapses. Ethanol, a psychotropic drug, is able to promote behavioral and neurophysiological changes, acting on different neurotransmitter systems, including the serotonergic, which has also been directly associated with aversive states, including anxiety. This study aimed to investigate the participation of type 7 serotonin receptor (5-HT7) of the dorsal periaqueductal gray (DPAG) on basal experimental anxiety and that caused by ethanol withdrawal. For this, 75-100 days old Wistar rats were subjected to two experiments. On the first one, animals underwent stereotactic surgery for implantation of guide cannulas used for administration of the drug directly into the DPAG. After seven days, the animals received doses of 2.5; 5 and 10 nmols of type 7 receptor antagonist SB269970 (SB) or vehicle intra-DPAG and, ten minutes after, they were exposed to elevated plus maze (EPM). In the following day, the animals were submitted to the same treatment and tested in the open field (OF). In the second experiment, animals received increasing concentrations (2%, 4%, 6%) of ethanol as the only source of liquid diet or water (control group), both with free access to chow. Seventy two hours and ninety six hours after the ethanol withdrawal, animals received SB (2.5 and 5.0 nmols) intraDPAG ten minutes before the test in the LCE and OF, respectively. In experiment 1, the dose of antagonist 10 nmols was able of reversing the anxiety generated by EPM. In the experiment 2, ineffective SB doses on the LCE (2.5 and 5.0 nmol) were not able to reverse the anxiety caused by the ethanol withdrawal in the EPM, although the dose of 2.5 nmols of SB has reversed its hipolocomotor effect in this test. This result suggests that the 5-HT7 receptor is involved in the modulation of the basal experimental anxiety in rats, but not in the anxiety caused by ethanol withdrawal in the DPAG.

Le cognitive enhancement en milieu universitaire : entre souffrance psychique individuelle, culture de performance et insécurités sociales

Ce projet de mémoire s’intéresse à la mise en relation du cognitive enhancement observé dans les universités occidentales contemporaines et de la société dans laquelle il s’insère. Nous avons voulu détacher la perspective du phénomène des analyses principalement orientées vers les programmes de sciences de la santé et de droit, ainsi que de l’approche quantitative, clinique, athéorique et somme toute moralisatrice qui lui est usuellement accordée afin d’explorer la nature des pratiques d’usages de psychotropes des étudiants universitaires en sciences humaines et sociales en vue d’augmenter leurs performances cognitives, d’approfondir la compréhension des raisonnements sous-jacents à ces pratiques, puis de resituer ces derniers dans leur contexte élargi. Nous avons interrogé treize étudiants de divers programmes de sciences humaines et sociales consommant, ou ayant déjà consommé, des psychotropes en vue de rehausser leurs performances cognitives en contexte académique. Les résultats suggèrent un écart dans la nature de leurs pratiques d’usage par rapport aux domaines d’études habituellement préconisés en ce sens qu’une grande variété de substances sont considérées comme supports cognitifs ; ensuite, que le recours aux psychotropes dans une visée de performance cognitive s’éloigne des logiques de la nécessité médicale et de la toxicomanie. En premier lieu, le cognitive enhancement est associé par plusieurs à une souffrance psychique liée à une perte de repères existentiels et les étudiants y ont recours dans une optique de compréhension de soi et de quête de repères dans un monde qu’ils ressentent comme instable. En second lieu, la consommation de psychotropes s’apparente davantage à un désir de satisfaire aux conditions incertaines et menaçantes des demandes externes de performance telles qu’ils les appréhendent qu’à un souci de soigner quelque condition médicale de la cognition. Nous pensons que le rapport au psychotrope qu’entretiennent les étudiants universitaires en sciences humaines et sociales s’insère en toute cohérence dans les discours et injonctions contemporaines de performance, en ce sens que leur souffrance psychique individuelle expose les limites de ce que la société attend d’eux.

Parents’ Perception of Medication Treatments for Preschool Children with or at – risk for ADHD

Introduction: ADHD is a chronic medical condition that affects 3-7% of school-aged children. Over the last few years, there has been increased attention with children in the preschool age range. The American Academy of Pediatrics (AAP) recommends that treatment for ADHD in the preschool age range should take the form of behavior modification first, with medication only considered after behavior modification is not effective alone in treating the symptoms (AAP, 2011). However, little research has been done to examine parent perceptions of evidence-based treatment approaches for children in the preschool age range. Objective: This study sought to examine parent perceptions of psychotropic medication use for preschool age (4-6 years) children with or at-risk of ADHD. Method: Data was collected from 176 families who presented for treatment at a clinic in southeast Florida. Parents completed questionnaires about their family background, their child’s behavior, behavioral functioning, and their perceptions of medication treatment. Results: Preliminary results indicate that 50% of parents were not open to the possibility of medication, 44.6% of parents were open to the possibility of medication, and 5.4% of parents chose against medication when a physician recommended it. Results examining the extent to which severity of child behavior problems impacts parent perceptions of medication will also be presented. Conclusion: These findings demonstrate that parents of preschool children are hesitant to consider medication as a treatment option for their young children. The findings of this study are important as more and more young children are being diagnosed with ADHD each year

Sentimentos de Paranóia e de Vergonha nos Sem-Abrigo

A população “sem-abrigo” e todos os problemas envolventes, como a pobreza e a exclusão social apresentam uma complexidade cada vez mais inquietante e preocupante na nossa sociedade. O fenómeno multifacetado dos sem-abrigo constitui um grave problema social. A pertinência deste estudo prende-se com a escassez de investigação relativa à população sem-abrigo e perceber melhor a sua complexidade, nomeadamente no que respeita à caracterização psicológica dos indivíduos sem-abrigo. Neste sentido, o presente estudo tem como objectivo conhecer melhor esta população através da recolha de informação relativa aos seus receios, valores, prazeres, percepção do motivo da sua situação, consumo de substâncias psicotrópicas, contacto com a família e amigos. Paralelamente pretendemos avaliar os sentimentos de vergonha (em função de experiências negativas precoces), de paranóia e emoções negativas (depressão, ansiedade e stress) nesta população específica e analisar a relação entre estas variáveis. A amostra é constituída por 56 sujeitos na condição de sem-abrigo, com uma média de idade de 40,86 e de 7 anos de escolaridade, sendo a maioria (n=49) do sexo masculino. O protocolo de avaliação, para além do questionário psicossocial desenvolvido para o efeito, incluía ainda escalas para medir a Depressão, Ansiedade e Stress (DASS-21), Vergonha Externa (OAS), Vergonha Interna (ISS) e Paranóia (GPS). Os dados do nosso estudo permitiram pôr em evidência algumas das dificuldades mais significativas dos sem-abrigo, nomeadamente, as rupturas dos laços familiares, o desemprego e a toxicodependência entre outros. Constatámos que os sem-abrigo da nossa amostra apresentam valores médios mais elevados de paranóia, vergonha externa e interna, quando comparados com os valores da população normal. Verifica-se ainda que quando mais escolarizada é a nossa amostra, menor sintomatologia depressiva e relacionada com o stress apresenta. Encontrámos correlações significativas positivas e moderadas entre as variáveis em estudo. Dada a escassez de investigação em indivíduos sem-abrigo, e apesar das limitações inerentes a este estudo, esperamos ter dado um contributo para alargar o conhecimento deste complexo fenómeno, nomeadamente no que respeita à caracterização psicológica destes indivíduos. / The homeless population and all the related issues such as poverty and social exclusion are a complex and increasingly worrying concern of our society. The multifaceted phenomenon of homelessness is a serious social problem. The relevance of this study relates to the scarcity of research on the homeless population and to better understand its complexity, particularly the psychological characteristics of the homeless individuals. As such, this study aims to better understand this population by collecting information on their fears, values, pleasures, perception of the reason for their situation, consumption of psychotropic substances, contact with family and friends. Simultaneously we intend to evaluate the feelings of shame (due to early negative experiences), paranoia and negative emotions (depression, anxiety and stress) in this specific population as well as analyse the relationship between these variables. The study sample is based on 56 individuals in the condition of homelessness, mostly male (n = 49), with an average age of 40.86 and 7 years of schooling. In addition to the psychological questionnaire developed for this purpose, the evaluation protocol also included scales to measure Depression, Anxiety and Stress (DASS-21), External Shame (OAS), Internal Shame (ISS) and Paranoia (GPS). The data in our study allowed to highlight some of the most significant problems of homelessness, including disruption of family ties, unemployment, drug abuse and others. We learnt that the homeless in our sample have a higher average number of paranoia, internal and external shame, when compared to the normal population. We have also found that the more educated our sample is, the less are the depressive symptoms and stress-related features. Among the studied variables, we have found significant positive and moderate correlations. Given the scarcity of research on homeless individuals and despite the limitations of this study, we hope to have contributed to increase the knowledge on this complex phenomenon, especially concerning the psychological characterization of these individuals.

A cocaína e suas manifestações orofaciais

A cocaína é uma droga com ação estimulante no sistema nervoso central, extraída e refinada a partir da planta de coca (Erythroxylum coca). É característica por induzir o consumidor a um estado de hipervigilância reduzindo ao mesmo tempo, o cansaço e a fadiga. Este pó branco, cristalino, de sabor amargo, possui também um efeito anestésico local e vasoconstritor. As formas de apresentação mais comuns da droga são o cloridrato de cocaína e a cocaína crack. Esta droga destaca-se por ser o estimulante mais consumido na Europa com cerca de 3,4 milhões de consumidores estimados no ano de 2014. A prevalência do consumo desta droga em Portugal aumentou 0,3% de 2001, para 2012 na população geral (15-64 anos). Os estudos mais recentes em populações escolares (entre 2010 e 2011) evidenciaram, de um modo geral, o aumento da prevalência de consumo nesta população. Os efeitos adversos resultantes, tanto a nível físico como psíquico, são vários, sendo as manifestações orofaciais as que mais interferem na Qualidade de vida do toxicómano. As manifestações mais frequentes são as perfurações do septo nasal e palatino, bruxismo, gengivite, erosão dentária, xerostomia, cárie, lesões brancas atípicas e cefaleias em salva, tendo o Médico Dentista um papel importante no diagnóstico e tratamento destas lesões. A legislação, ao nível Europeu, sobre drogas procura uma uniformização das medidas aplicadas nos países membros, baseando-se no equilíbrio entre as sanções e o tratamento. Apesar das convenções das Nações Unidas sobre drogas limitarem o consumo de estupefacientes e substâncias psicotrópicas exclusivamente para fins médicos e científicos, cabe aos países signatários a liberdade de decisão das políticas a adoptar em matérias de infrações penais como a posse e o consumo ilegal.

Perto de ti, matas. Longe de ti, eu morro: Uma etnografia sobre usos de drogas de rua

O presente documento apresenta uma etnografia, realizada numa freguesia de Vila Nova de Gaia, sobre o uso, em contexto de rua, de substâncias denominadas "pesadas". Partindo de uma linha teórico­ metodológica que se demarca dos paradigmas tradicionais que perspectivam o fenómeno droga através das dimensões da delinquência ou da patologia, procedemos a uma análise, em contexto natural, dos espaços e actores relacionados com o psicotropismo. Concluímos que uma relação de dependência com as drogas emerge de uma dimensão processual, para a qual contribui o contexto sociocultural e o quadro relacional onde o indivíduo se insere. Daí, recorrermos ao conceito de itinerário de consumo na abordagem das relações estabelecidas com as substâncias. ABSTRACT; This document presents an ethnography, developed in Vila Nova de Gaia, about consumption, in street environment, of as common sense defines "hard" drugs. Through a theoretical and methodological approach that makes a difference among the traditional paradigms, which conceive the drug phenomenon under the delinquency and pathological dimensions, we analyse, in natural environment, the places and the actors which are involved in the drug scene. We concluded that the drug addiction relationship comes from a sequential dimension, in which sociocultural environment and relationship background make a contribution. Is that the reason why we use consumption itinerary concept to approach the relations between individual and drugs.

Lost in translation? The potential psychobiotic Lactobacillus rhamnosus (JB-1) fails to modulate stress or cognitive performance in healthy male subjects

Background: Preclinical studies have identified certain probiotics as psychobiotics a live microorganisms with a potential mental health benefit. Lactobacillus rhamnosus (JB-1) has been shown to reduce stress-related behaviour, corticosterone release and alter central expression of GABA receptors in an anxious mouse strain. However, it is unclear if this single putative psychobiotic strain has psychotropic activity in humans. Consequently, we aimed to examine if these promising preclinical findings could be translated to healthy human volunteers. Objectives: To determine the impact of L. rhamnosus on stress-related behaviours, physiology, inflammatory response, cognitive performance and brain activity patterns in healthy male participants. An 8 week, randomized, placebo-controlled, cross-over design was employed. Twenty-nine healthy male volunteers participated. Participants completed self-report stress measures, cognitive assessments and resting electroencephalography (EEG). Plasma IL10, IL1β, IL6, IL8 and TNFα levels and whole blood Toll-like 4 (TLR-4) agonist-induced cytokine release were determined by multiplex ELISA. Salivary cortisol was determined by ELISA and subjective stress measures were assessed before, during and after a socially evaluated cold pressor test (SECPT). Results: There was no overall effect of probiotic treatment on measures of mood, anxiety, stress or sleep quality and no significant effect of probiotic over placebo on subjective stress measures, or the HPA response to the SECPT. Visuospatial memory performance, attention switching, rapid visual information processing, emotion recognition and associated EEG measures did not show improvement over placebo. No significant anti-inflammatory effects were seen as assessed by basal and stimulated cytokine levels. Conclusions: L. rhamnosus was not superior to placebo in modifying stress-related measures, HPA response, inflammation or cognitive performance in healthy male participants. These findings highlight the challenges associated with moving promising preclinical studies, conducted in an anxious mouse strain, to healthy human participants. Future interventional studies investigating the effect of this psychobiotic in populations with stress-related disorders are required.

Estado de las enfermedades raras que cursan con discapacidad intelectual en Colombia

Las enfermedades raras o huérfano son una problemática que ha tomado mucha importancia en el contexto mundial del presente siglo, estas se han definido como crónicas, de difícil tratamiento de sus síntomas y con baja prevalencia en la población; muchas de estas enfermedades cursan con varios tipos de discapacidad, siendo el objetivo del presente trabajo el enfocarse en aquellas enfermedades raras que cursan con discapacidad intelectual. Para poder profundizar en estas enfermedades se realizó una revisión teórica sobre las enfermedades raras, así como de la discapacidad psíquica y su importancia a nivel mundial y nacional. A partir de estas definiciones, se revisaron en profundidad 3 enfermedades raras que cursan con discapacidad intelectual en el contexto colombiano, como son: el síndrome de Rett, el síndrome de Prader-Willi y el síndrome de X frágil. En cada una de estas enfermedades además se explicaron los tipos de diagnóstico, intervención, prevención, grupos de apoyo y tipos de evaluación que más se usan en el contexto nacional

The psychoactive effects of “Light Cannabis”. From Italian law to psychopharmacology

In 2019, the Italian Supreme Court established that hemp, for non-medical use, cannot be commercialized for human use, when the “psychotropic effect” of the product or its “offensiveness” can be demonstrated. The first chapter of this work reports a review of the European and Italian legislation on hemp cultivation, as well as the hemp production chain and commercial activities. The second chapter reports the pharmacological aspects and the psychoactive effects of light cannabis, along with pharmacokinetics of the main Cannabis compounds: Δ9-tetrahydrocannabinol (Δ9-THC), Cannabidiol (CBD) and Cannabinol (CBN). The aim of the experimental study, reported in the third chapter, is to assess Δ9-THC and CBD blood concentrations after smoking “light cannabis”, and its effects on vigilance, cognitive and motor skills. Eighteen young adults consumed three light cannabis cigarettes with a percentage of 0.41% of Δ9-THC and of 12.41% of CBD. Blood samples were collected before the experiment (t0) and after pre-defined time-lapses. Five performance tasks and a subjective scale were employed for measuring cognitive and psychomotor performances the day before the experiment (TT0) and after the third cigarette (TT1). Mean (SD) concentrations (ng/ml) were between 1.0(0.8) in t1 and 0.3(0.3) in t5 for Δ9-THC; and 10.5(10.3) in t1 and 5.7(5.7) in t5 for CBD. No significant differences were observed between TT0 and TT1 for all performed psychomotor performance task. Δ9-THC and CBD concentrations showed a high inter-subject variability, and the average concentrations were lower than those previously reported. Toxicological results showed a decrease of Δ9-THC and CBD after the third light cannabis cigarette, and a Δ9-THC /CBD ratio always < 1 was observed. This value might be useful in discriminating light cannabis versus illegal/medical cannabis consumption. The lack of impairment observed in our participants can be interpreted as a consequence of the very low concentrations in the blood.
