Neither sensation seeking nor neuroticism were related to acquisition learning and neuroticism was neither related to avoidance nor extinction. Transcranial direct currentstimulation administered before extinction did not influence present results. Results highlight the important role of elevated avoidance propensity in fear maintenance. Results moreover provide evidence for reduced sensation-seeking and increased acquisition learning to be avoidance-driving mechanisms. Since approach-avoidance conflicts are faced by anxiety patients on a daily basis, strengthening sensation-seeking-congruent attitudes and approach behaviours may optimize individualized treatment.Serum levels of carbon dioxide (CO2) closely regulate cerebral blood flow (CBF) and actively participate in different aspects of brain physiology such as hemodynamics, oxygenation, and metabolism. Fluctuations in the partial pressure of arterial CO2 (PaCO2) modify the aforementioned variables, and at the same time influence physiologic parameters in organs such as the lungs, heart, kidneys, and the gastrointestinal tract. In general, during acute brain injury (ABI), maintaining normal PaCO2 is the target to be achieved. https://www.selleckchem.com/products/ecc5004-azd5004.html Both hypercapnia and hypocapnia may comprise secondary insults and should be avoided during ABI. The risks of hypocapnia mostly outweigh the potential benefits. Therefore, its therapeutic applicability is limited to transient and second-stage control of intracranial hypertension. On the other hand, inducing hypercapnia could be beneficial when certain specific situations require increasing CBF. The evidence supporting this claim is very weak. This review attempts providing an update on the physiology of CO2, its risks, benefits, and potential utility in the neurocritical care setting.

Cardiac complications are common after spontaneous intracerebral hemorrhage (ICH). In this study we intended to investigate factors associated with higher alterations in heart rate and their impact on outcome.

Eighty-eight ICH patients were included. A simplified approach to calculate heart rate variability (HR

) in analogy to systolic blood pressure variability (SBP

) with daily standard deviations of HR in the acute (first 24h) and subacute phase (day1-day7) was used. Using multivariable regression, factors associated with higher HR

and the association between higher HR

and poor 3-month outcome (modified Rankin Scale>3) were analyzed. All models were adjusted for age, atrial fibrillation, mechanical ventilation, vasopressor administration, and mean HR.

Patients were 71 (IQR=60-79) years old and presented with an admission ICH-Score of 2 (IQR=1-3). In multivariable analysis, intraventricular hemorrhage (adjOR=8.66, 95%-CI=1.89-39.60, p=0.005), a QRS complex >120ms (adjOR=19.02; 95%-CI=2.08-175.05, p=0.009) and female sex (adjOR=4.24; 95%-CI=1.08-16.64, p=0.038) were associated with higher HR

in the acute phase. A higher HR

(adjOR=1.29, 95%-CI=1.01-1.66, p=0.045) in the acute but not in the subacute phase (p=0.764) was associated with poor 3-month outcome.

The study suggests that a higher variation in heart rate in the early phase after ICH may discriminate patients with poor outcome.

Currently, no ground contact countermeasures have been implemented and no pedestrian model has been validated for ground contact, though this is needed for developing future ground contact injury countermeasures. In this paper, we assess the predictive capacity of the MADYMO ellipsoid pedestrian model in reconstructing six recent pedestrian cadaver ground contact experiments. Whole-body kinematics as well as vehicle and ground contact related aHIC (approximate HIC) and BrIC scores were evaluated. Reasonable results were generally achieved for the timings of the principal collision events, and for the overall ground contact mechanisms. However, the resulting head injury predictions based on the ground contact HIC and BrIC scores showed limited capacity of the model to replicate individual experiments. Sensitivity studies showed substantial influences of the vehicle-pedestrian contact characteristic and certain initial pedestrian joint angles on the subsequent ground contact kinematics and injury predictions. Further work is needed to improve the predictive capacity of the MADYMO pedestrian model for ground contact injury predictions.

Acupuncture has been found to be an effective treatment for insomnia. but it is not clear whether acupuncture is just a placebo effect. We aimed to compare the efficacy and safety of acupuncture and sham/placebo acupuncture.

We searched the Central Register of Controlled Trials of Medline, EMBASE, and Cochrane from database inception through March 16, 2020 for randomized controlled trials (RCTs) that compared acupuncture therapy with sham/placebo acupuncture or no treatment. Restricted to English language. Cochrane risk of bias tool was used to analyze risk of bias of the included randomized controlled trials (RCT). Data analysis was performed with Review Manager 5.3.

A total of 15 studies involving 1108 patients. Meta-analysis results showed that acupuncture therapy was superior to sham/placebo acupuncture in terms of improving Pittsburgh sleep quality index (PSQI), insomnia severity index (ISI), total sleep time (TST), sleep-onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE), ev Types of acupuncture therapy and placebo may underestimate the efficacy of acupuncture in different ways.This 3-year longitudinal study examined the extent to which body weight contingent self-worth (CSW) predicted depressive symptoms in 439 adolescent girls and the roles of unstable self-esteem and interpersonal sexual objectification in this association. Half-longitudinal mediation showed that the indirect effect of body weight CSW on depression via instability of self-esteem was significant. Prior levels of body weight CSW predicted increases in unstable self-esteem, which predicted increments in depressive symptoms over time. However, earlier levels of depression did not significantly predict increases in self-esteem instability. Moderation analyses indicated that the indirect effect was conditional upon individuals' experience of interpersonal sexual objectification. The positive link between body weight CSW and unstable self-esteem was stronger in girls who experienced more interpersonal sexual objectification. The direct effect of body weight CSW on depression was also moderated by interpersonal sexual objectification.
