Attentional control is crucial for selectively attending to relevant information when our brain is confronted with a multitude of sensory signals. Graph-theoretical measures provide a powerful tool for investigating the efficiency of brain network communication in separating and integrating information. Albeit it has been demonstrated that atDCS can boost auditory attention in situations with high control demands, its effect on neurophysiological mechanisms of functional brain network communication in situations when attentional focus conflicts with perceptual saliency remain unclear. This study investigated the effects of atDCS on network connectivity and theta oscillatory power under different levels of attentional-perceptual conflict. We hypothesized that the benefit of atDCS on network communication efficiency would be particularly apparent in conditions requiring high attentional control. Thirty young adults participated in a dichotic listening task with intensity manipulation while EEG activity was recorded. find more In a cross-over design, participants underwent right frontal atDCS and sham stimulations in two separate sessions. Time-frequency decomposition and graph-theoretical analyses of network efficiency (using 'small-world' properties) were used, respectively, to quantify theta oscillatory power and brain network efficiency. The atDCS-induced effect on task efficiency in the most demanding condition was mirrored only by an increase in network efficiency during atDCS compared to sham stimulation. These findings are corroborated by Bayesian analyses. AtDCS-induced performance enhancement under high levels of attentional-perceptual conflicts is accompanied by an increase in network efficiency. Graph-theoretical measures can serve as a metric to quantify the effects of non-invasive brain stimulation on the separation and integration of information in the brain.Carcinoids of the left main bronchus are rare tumors of the bronchial system and patients often present with dyspnea, asthma-like symptoms, and pneumonia. Gold standard for therapy of carcinoids is surgical resection, but the surgical approach for segmental resection and anastomosis of the left main bronchus is a matter of discussion. With a left-sided approach the access to the bronchus is blocked by the aortic arch and the pulmonary vein. If a right-sided approach is performed, the problem of ventilation during resection and anastomosis of the bronchus occurs. We present a surgical approach from the right side using intraoperative extracorporeal membrane oxygenation to assure oxygen supply for resection of a typical carcinoid of the left main stem bronchus, and discuss the current literature.Idiopathic aneurysm of pulmonary artery is a rare disorder with unclear pathology and mechanism. The indications for its surgical treatment are not clear, especially in cases with normal pulmonary pressure. We report the case of a 64-year-old man with a giant idiopathic aneurysm of the pulmonary artery (max diameter 97.3 mm). The patient successfully underwent surgical treatment with the aneurysmorrhaphy in our Department of Cardiovascular and Thoracic Surgery. The patient was extubated successfully within 6 hours of the operation and discharged hospital after 10 days. In cases with giant aneurysm of the pulmonary artery, the aneurysmorrhaphy may be considered as a safe and feasible choice.Community paramedicine (CP) is an evolving method of providing community-based health care in which paramedics function outside of their traditional emergency response roles in order to improve access to primary and preventive health care and to basic social services. Early evidence indicates that CP programs have contributed to reducing health care utilization and improving patient outcomes leading some to call for a transformation of EMS into value-based mobile healthcare fully integrated within an interprofessional care team. The purpose of this scoping review was to understand the evidence base of CP in order to inform the further evolution of this model of care. Following the PRISMA extension for Scoping Reviews, 1,163 titles were screened by our research team. Eligibility criteria were publication in English after January 1, 2000; description of a CP program located in a Western nation; and inclusion of a discussion of outcomes. Twenty-nine publications met the criteria for inclusion. The literature was varied in terms of study design, program purpose, and target audience. The lack of rigorous, longitudinal studies with control groups makes rendering conclusions as to the value and effectiveness of CP programs difficult. Further, the extent to which community paramedics operate within interprofessional teams remains unclear. However, some programs demonstrated improvement in both health services and patient outcomes. As stakeholders continue to explore the potential of CP, results of this review highlight the importance of further investigation of outcomes, the professional identity of the community paramedic, and the role of the community paramedic on interprofessional teams.Little is known about the impact of attention during motor adaptation tasks on how movements adapted in one context generalize to another. We investigated this by manipulating subjects' attention to their movements while exposing them to split-belt walking (i.e., legs moving at different speeds), which is known to induce locomotor adaptation. We hypothesized that reducing subjects' attention to their movements by distracting them as participants adapted their walking pattern would facilitate the generalization of recalibrated movements beyond the training environment. We reasoned that awareness of the novel split-belt condition could be used to consciously contextualize movements to that particular situation. To test this hypothesis, young adults adapted their gait on a split-belt treadmill while they observed visual information that either distracted them or made them aware of the belt's speed difference. We assessed adaptation and aftereffects of spatial and temporal gait features known to adapt and generalize differently in different environments. We found that all groups adapted similarly by reaching the same steady state values for all gait parameters at the end of the adaptation period. In contrast, both groups with altered attention to the split-belts environment (distraction and awareness groups) generalized their movements from the treadmill to overground more than controls, who walked without altered attention. This was specifically observed in the generalization of step time (temporal gait feature) which might be less susceptible to online corrections when walking overground. These results suggest that altering attention to one's movements during sensorimotor adaptation facilitates the generalization of movement recalibration.
