Opioid misuse in patients with cancer pain: an integrative systematic review of the literature
Introducción: los opioides son ampliamente utilizados para el control del dolor oncológico y no oncológico. Existe mucha información sobre el uso inadecuado de opioides (UIO) en pacientes no oncológicos, sin embargo en pacientes oncológicos existe menos evidencia. Objetivos: identificar, analizar y sintetizar la evidencia disponible sobre la epidemiología, los factores de riesgo, instrumentos clínicos y evolución del UIO en pacientes con dolor oncológico. Material y métodos: revisión sistemática integradora de la literatura con extracción de datos y síntesis narrativa. Las fuentes utilizadas para buscar artículos publicados hasta el 31 de diciembre de 2017 fueron las bases de datos PubMed, Web of Science y PsychINFO. Se eligieron aquellos artículos que siguieran los siguientes criterios de inclusión: 1) publicados en lengua inglesa, española o francesa, y 2) que incluyesen información sobre la prevalencia o incidencia del UIO en pacientes con dolor oncológico, o/y 3) que aportasen información sobre factores de riesgo, mortalidad, duración del UIO y su remisión. Resultados: De la búsqueda surgieron 3520 artículos, de los cuales 40 cumplieron los criterios de inclusión. Se identificaron cuatro áreas temáticas: 1) epidemiología, 2) factores de riesgo, 3) opinión de pacientes y profesionales, y 4) políticas específicas. Los resultados obtenidos fueron muy heterogéneos, identificándose una prevalencia que oscila entre el 0 y el 26 % en el UIO y entre el 12 y el 85 % en las conductas aberrantes relacionadas con opioides. Se identificaron diferentes factores de riesgo de UIO, destacando la edad joven y la presencia de antecedentes psiquiátricos o de abuso de sustancias, y se describieron diferentes instrumentos dirigidos a la evaluación del riesgo o bien al diagnóstico del UIO. En cuanto a la opinión de los profesionales, parece haber un incremento de la sensibilización al respecto, pero las políticas de los centros en relación con esta problemática suelen ser casi inexistentes. Conclusiones: A pesar de que existe una mayor sensibilización de los profesionales acerca del UIO en pacientes oncológicos, la información de que disponemos es muy heterogénea y no nos permite extraer conclusiones claras. Por esta razón será necesaria la realización de nuevos estudios intentando homogeneizar criterios y establecer mejores protocolos y políticas de detección e intervención frente al UIO
ICOnnecta't: Development and Initial Results of a Stepped Psychosocial eHealth Ecosystem to Facilitate Risk Assessment and Prevention of Early Emotional Distress in Breast Cancer Survivors' Journey
Psychosocial interventions prevent emotional distress and facilitate adaptation in breast cancer (BC). However, conventional care presents accessibility barriers that eHealth has the potential to overcome. ICOnnecta't is a stepped digital ecosystem designed to build wellbeing and reduce psychosocial risks during the cancer journey through a European-funded project. Women recently diagnosed with BC in a comprehensive cancer center were offered the ecosystem. ICOnnecta't consists of four care levels, provided according to users' distress: screening and monitoring, psychoeducation campus, peer-support community, and online-group psychotherapy. Descriptive analyses were conducted to assess the platform's implementation, while multilevel linear models were used to study users' psychosocial course after diagnosis. ICOnnecta't showed acceptance, use and attrition rates of 57.62, 74.60, and 29.66%, respectively. Up to 76.19% of users reported being satisfied with the platform and 75.95% informed that it was easy to use. A total of 443 patients' needs were detected and responsively managed, leading 94.33% of users to remain in the preventive steps. In general, strong social support led to a better psychosocial course. ICOnnecta't has been successfully implemented. The results showed that it supported the development of a digital relation with healthcare services and opened new early support pathways
Altered corticostriatal functional connectivity in obsessive-compulsive disorder
Context: neurobiological models of obsessive-compulsive disorder (OCD) emphasize disturbances in the function and connectivity of brain corticostriatal networks, or 'loops.' Although neuroimaging studies of patients have supported this network model of OCD, very few have applied measurements that are sensitive to brain connectivity features. Objective: using resting-state functional magnetic resonance imaging, we tested the hypothesis that OCD is associated with disturbances in the functional connectivity of primarily ventral corticostriatal regions, measured from coherent spontaneous fluctuations in the blood oxygenation level-dependent (BOLD) signal. Design: case-control cross-sectional study. Setting: hospital referral OCD unit and magnetic resonance imaging facility. Participants: a total of 21 patients with OCD (10 men, 11 women) and 21 healthy control subjects matched for age, sex, and estimated intelligence. Main outcome measures: voxelwise statistical parametric maps testing the strength of functional connectivity of 4 striatal seed regions of interest (dorsal caudate nucleus, ventral caudate/nucleus accumbens, dorsal putamen, and ventral putamen) with remaining brain areas. Results: for both groups, there was a clear distinction in the pattern of cortical connectivity of dorsal and ventral striatal regions, consistent with the notion of segregated motor, associative, and limbic corticostriatal networks. Between groups, patients with OCD had significantly increased functional connectivity along a ventral corticostriatal axis, implicating the orbitofrontal cortex and surrounding areas. The specific strength of connectivity between the ventral caudate/nucleus accumbens and the anterior orbitofrontal cortex predicted patients' overall symptom severity (r(2) = 0.57; P < .001). Additionally, patients with OCD showed evidence of reduced functional connectivity of the dorsal striatum and lateral prefrontal cortex, and of the ventral striatum with the region of the midbrain ventral tegmental area. Conclusions: this study directly supports the hypothesis that OCD is associated with functional alterations of brain corticostriatal networks. Specifically, our findings emphasize abnormal and heightened functional connectivity of ventrolimbic corticostriatal regions in patients with OCD

Task-induced deactivation from rest extends beyond the default mode brain network
Activity decreases, or deactivations, of midline and parietal cortical brain regions are routinely observed in human functional neuroimaging studies that compare periods of task-based cognitive performance with passive states, such as rest. It is now widely held that such task-induced deactivations index a highly organized"default-mode network" (DMN): a large-scale brain system whose discovery has had broad implications in the study of human brain function and behavior. In this work, we show that common task-induced deactivations from rest also occur outside of the DMN as a function of increased task demand. Fifty healthy adult subjects performed two distinct functional magnetic resonance imaging tasks that were designed to reliably map deactivations from a resting baseline. As primary findings, increases in task demand consistently modulated the regional anatomy of DMN deactivation. At high levels of task demand, robust deactivation was observed in non-DMN regions, most notably, the posterior insular cortex. Deactivation of this region was directly implicated in a performance-based analysis of experienced task difficulty. Together, these findings suggest that task-induced deactivations from rest are not limited to the DMN and extend to brain regions typically associated with integrative sensory and interoceptive processes
Brain Volumetric Correlates of Right Unilateral Versus Bitemporal Electroconvulsive Therapy for Treatment-Resistant Depression.
Objective: The selection of a bitemporal (BT) or right unilateral (RUL) electrode placement affects the efficacy and side effects of ECT. Previous studies have not entirely described the neurobiological underpinnings of such differential effects. Recent neuroimaging research on gray matter volumes is contributing to our understanding of the mechanism of action of ECT and could clarify the differential mechanisms of BT and RUL ECT. Methods: To assess the whole-brain gray matter volumetric changes observed after treating patients with treatment-resistant depression with BT or RUL ECT, the authors used MRI to assess 24 study subjects with treatment-resistant depression (bifrontotemporal ECT, N=12; RUL ECT, N=12) at two time points (before the first ECT session and after ECT completion). Results: Study subjects receiving BT ECT showed gray matter volume increases in the bilateral limbic system, but subjects treated with RUL ECT showed gray matter volume increases limited to the right hemisphere. The authors observed significant differences between the two groups in midtemporal and subcortical limbic structures in the left hemisphere. Conclusions: These findings highlight that ECT-induced gray matter volume increases may be specifically observed in the stimulated hemispheres. The authors suggest that electrode placement may relevantly contribute to the development of personalized ECT protocols
Neural correlates of moral sensitivity in obsessive-compulsive disorder
Context: heightened moral sensitivity seems to characterize patients with obsessive-compulsive disorder (OCD). Recent advances in social cognitive neuroscience suggest that a compelling relationship may exist between this disorder-relevant processing bias and the functional activity of brain regions implicated in OCD. Objective: to test the hypothesis that patients with OCD demonstrate an increased response of relevant ventromedial prefrontal and orbitofrontal cortex regions in a functional magnetic resonance imaging study of difficult moral decision making. Design: case-control cross-sectional study. Setting: hospital referral OCD unit and magnetic resonance imaging facility. Participants: seventy-three patients with OCD (42 men and 31 women) and 73 control participants matched for age, sex, and education level. Main outcome measures: functional magnetic resonance imaging activation maps representing significant changes in blood oxygenation level-dependent signal in response to 24 hypothetical moral dilemma vs nondilemma task vignettes and additional activation maps representing significant linear associations between patients' brain responses and symptom severity ratings. Results: in both groups, moral dilemma led to robust activation of frontal and temporoparietal brain regions. Supporting predictions, patients with OCD demonstrated significantly increased activation of the ventral frontal cortex, particularly of the medial orbitofrontal cortex. In addition, the left dorsolateral prefrontal cortex and left middle temporal gyrus were more robustly activated in patients with OCD. These results were unexplained by group differences in comorbid affective symptoms. Patients' global illness severity predicted the relative magnitude of orbitofrontal-striatal activation. The severity of 'harm/checking' symptoms and 'sexual/religious' obsessions predicted the magnitude of posterior temporal and amygdala-paralimbic activation, respectively. Conclusions: the neural correlates of moral sensitivity in patients with OCD partly coincide with brain regions that are of general interest to pathophysiologic models of this disorder. In particular, these findings suggest that the orbitofrontal cortex together with the left dorsolateral prefrontal cortex may be relevant for understanding the link between neurobiological processes and certain maladaptive cognitions in OCD
Surface indicators are correlated with soil multifunctionality in global drylands
Multiple ecosystem functions need to be considered simultaneously to manage and protect the several ecosystem services that are essential to people and their environments. Despite this, cost effective, tangible, relatively simple and globally relevant methodologies to monitor in situ soil multifunctionality, that is, the provision of multiple ecosystem functions by soils, have not been tested at the global scale. We combined correlation analysis and structural equation modelling to explore whether we could find easily measured, field-based indicators of soil multifunctionality (measured using functions linked to the cycling and storage of soil carbon, nitrogen and phosphorus). To do this, we gathered soil data from 120 dryland ecosystems from five continents. Two soil surface attributes measured in situ (litter incorporation and surface aggregate stability) were the most strongly associated with soil multifunctionality, even after accounting for geographic location and other drivers such as climate, woody cover, soil pH and soil electric conductivity. The positive relationships between surface stability and litter incorporation on soil multifunctionality were greater beneath the canopy of perennial vegetation than in adjacent, open areas devoid of vascular plants. The positive associations between surface aggregate stability and soil functions increased with increasing mean annual temperature. Synthesis and applications. Our findings demonstrate that a reduced suite of easily measured in situ soil surface attributes can be used as potential indicators of soil multifunctionality in drylands world-wide. These attributes, which relate to plant litter (origin, incorporation, cover), and surface stability, are relatively cheap and easy to assess with minimal training, allowing operators to sample many sites across widely varying climatic areas and soil types. The correlations of these variables are comparable to the influence of climate or soil, and would allow cost-effective monitoring of soil multifunctionality under changing land-use and environmental conditions. This would provide important information for evaluating the ecological impacts of land degradation, desertification and climate change in drylands world-wide.Fil: Eldridge, David J..
