Brain dynamics of post‐task resting state are influenced by expertise: Insights from baseball players

Post‐task resting state dynamics can be viewed as a task‐driven state where behavioral performance is improved through endogenous, non‐explicit learning. Tasks that have intrinsic value for individuals are hypothesized to produce post‐task resting state dynamics that promote learning. We measured simultaneous fMRI/EEG and DTI in Division‐1 collegiate baseball players and compared to a group of controls, examining differences in both functional and structural connectivity. Participants performed a surrogate baseball pitch Go/No‐Go task before a resting state scan, and we compared post‐task resting state connectivity using a seed‐based analysis from the supplementary motor area (SMA), an area whose activity discriminated players and controls in our previous results using this task. Although both groups were equally trained on the task, the experts showed differential activity in their post‐task resting state consistent with motor learning. Specifically, we found (1) differences in bilateral SMA–L Insula functional connectivity between experts and controls that may reflect group differences in motor learning, (2) differences in BOLD‐alpha oscillation correlations between groups suggests variability in modulatory attention in the post‐task state, and (3) group differences between BOLD‐beta oscillations that may indicate cognitive processing of motor inhibition. Structural connectivity analysis identified group differences in portions of the functionally derived network, suggesting that functional differences may also partially arise from variability in the underlying white matter pathways. Generally, we find that brain dynamics in the post‐task resting state differ as a function of subject expertise and potentially result from differences in both functional and structural connectivity.

Chronic Obstructive Pulmonary Disease and Heart Failure

Chronic obstructive pulmonary disease (COPD) is commonly associated with heart failure. Individuals with COPD have a 4.5-fold greater risk of developing heart failure than those without. The sensitivity and specificity of clinical judgment in the diagnosis of heart failure in patients with COPD can be enhanced by biological markers such as B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide. Correct interpretation of imaging results (mainly echocardiographic findings) and lung function tests can also help establish the co-occurrence of both conditions. There is little evidence on the management of patients with COPD and heart failure, although treatment of COPD undeniably affects the clinical course of patients with heart failure and viceversa.     

Lung Cancer and COPD: a Common Combination

Background and objectiveTo analyse frequency, characteristics and patient survival with lung cancer (LC) and Common Obstructive Pulmonary Disease (COPD), comparing them with patients that do not have COPD.Material and methodsA retrospective study, of patients diagnosed by means of cytohistology. Survival was estimated by the Kaplan-Meier method. Statistical analysis was carried out using SPSS 15.0.ResultsA total of 996 patients were diagnosed, 39.8% with COPD. Mean age70±9.19 years. GOLD stages: I 18.2%, II 53.6%, III 24%, IV 4.2%. The histological types: squamous cell carcinoma 48.2%, adenocarcinoma 22%, and small cell carcinoma 22.5%. Survival was longer in the COPD group.ConclusionsLC and COPD are combined in 39.8%. Squamous cell type is more frequent and survival was longer in the COPD group.     

Prevention of overweight and obesity from a public health perspective

International organizations have raised awareness of the increasing prevalence of overweight and obesity worldwide and the impact on morbidity, mortality, quality of life, and cost of healthcare. The development and implementation of obesity prevention strategies requires the identification and understanding of determinant factors that can be influenced by effective large-scale action plans over time. Strategies aimed at the primary prevention of obesity in a population should be multifaceted and designed to actively involve stakeholders and other major parties concerned; in addition, multiple settings for implementation should be considered. In this paper, an overview is presented of the strategies currently in place for obesity prevention, particularly in Spain.     

El torbellino de la violencia. Relatos biográficos de mujeres que sufren maltrato

ObjectivesTo analyse the experience from the point of view of women who have suffered domestic violence. To identify factors related to continuing or resolving the problem.DesignQualitative interpretative research from a phenomenological perspective.Population sampleWomen, detected in primary care, who have suffered domestic violence and have recognised the problem, and who accepted to participate in this research.Multicentre StudySix health centres in the city of Malaga.Methods and techniquesThe technique used is the biographical narration using individual open interviews between social workers and women. This narration was tape-recorded and verbatim transcribed to written text. Grounded theory. Qualitative analysis was made with ATLAS-TI 5.2.OutcomesA total of 35 narrations were analysed. The abuse situation was described as “whirl-wind” metaphor (blindness-isolation-helplessness-suffering-destiny-dependence-fantasies -about love, protection, happiness, change- and vicious circles). Enduring experience is reported to be related to several factors: inculcated gender values, family-ideal, uncertainty, annulment, personal failure sensation, love, support defects, self-image, children protection, multiple fears and material aspects. They identified two types of “exit”: passive and active with different mechanisms and repercussions. Exit experience is related to: limit situations, children intervention, family ideal attempts, and fear-loss. Leaving is a transitional process or “pathway”. Institutional support is not always guaranteed and emotional support is better evaluated than a legal one.ConclusionsEnduring and coming out are reported as two qualitatively different states, which involve many cultural and personal factors. There is a gap between these two states with a process that varies depending on the involvement of the women in decision-making.
