A history of concussions is associated with symptoms of common mental disorders in former male professional athletes across a range of sports

Objective: Recent reports suggest that exposure to repetitive concussions in sports is associated with an increased risk of symptoms of distress, anxiety and depression, sleep disturbance or substance abuse/dependence (typically referred as symptoms of common mental disorders[CMD]) and of later development of neurodegenerative disease, in particular chronic traumatic encephalopathy (CTE). The primary aim of this study was to explore the relationship between sports career-related concussions and the subsequent occurrence of symptoms of CMD among former male professional athletes retired from football (soccer), ice hockey and rugby (union). Methods: Cross-sectional analyses were performed on baseline electronic questionnaires from three prospective cohort studies among former male professional athletes retired from football (soccer), ice hockey and rugby (union). The number of confirmed concussions was examined through a single question, while symptoms of distress, anxiety and depression, sleep disturbance and adverse alcohol use were assessed using validated questionnaires. Results: From 1,957 former professional athletes contacted, a total of 576 (29%) completed the questionnaire. Of these, 23% had not incurred a concussion during their career, 34% had two or three, 18% four or five, and 11% six or more concussions. The number of sports career-related concussions was a predictor for all outcome measures (β = 0.072–0.109; P ≤ 0.040). Specifically, former professional athletes who reported a history of four or five concussions were approximately 1.5 times more likely to report symptoms of CMD, rising to a two- to five-fold increase in those reporting a history of six or more sports career-related concussions. Conclusions: These data demonstrate an association between exposure to sports concussion and subsequent risk of symptoms of CMD in former professional athletes across a range of contact sports. Further work to explore the association between sports concussion and symptoms of CMD is required; in the meanwhile, strategies for effective risk reduction and improved management appear indicated

One-dimensional fluids with second nearest-neighbor interactions

As is well known, one-dimensional systems with interactions restricted to first nearest neighbors admit a full analytically exact statistical-mechanical solution. This is essentially due to the fact that the knowledge of the first nearest-neighbor probability distribution function, $p_1(r)$, is enough to determine the structural and thermodynamic properties of the system. On the other hand, if the interaction between second nearest-neighbor particles is turned on, the analytically exact solution is lost. Not only the knowledge of $p_1(r)$ is not sufficient anymore, but even its determination becomes a complex many-body problem. In this work we systematically explore different approximate solutions for one-dimensional second nearest-neighbor fluid models. We apply those approximations to the square-well and the attractive two-step pair potentials and compare them with Monte Carlo simulations, finding an excellent agreement.Comment: 26 pages, 12 figures; v2: more references adde

Magnetotransport in perovskite series La_{n-nx}Ca_{1＋nx}Mn_nO_{3n＋1} ferromagnets

The perovskite series La_{n-nx}Ca_{1＋nx}Mn_nO_{3n＋1｝(n=2,3,and ∞)composed of n layers of MnO2 is a colossal magnetoresistance (CMR) ferromagnet. Results on the transport properties of epitaxial a-axis thin-film samples with a fixed carrier concentration (x=0.3) have indicated that a reduction in the number of layers results in systematic changes in the various features. These include an increase in resistivity, a decrease in the resistivity peak temperature Tρc corresponding to the metal-insulator transition, an enhancement of the maximum MR near Tρc, and an increase in the low-temperature intrinsic MR. In order to explain the variation in these features with the number of MnO2 layers, it is necessary to take both c-axis transfer interaction and two-dimensional spin fluctuation into account.journal articl

Tunesiens Wahl setzt ein Zeichen, eine Wende ist sie nicht: Nach der Parlamentswahl blockiert der Konflikt um Staats- und Gesellschaftsmodell weiterhin Institutionen und Reformen

Die Parlamentswahl vom 26. Oktober zeigt, dass viele Wähler ein islamistisches Staatsmodell für Tunesien ablehnen. Sie verdeutlicht auch, wie zersplittert und zerstritten die Befürworter eines säkularen Modells sind, obwohl ihre Zusammenarbeit mehr denn je notwendig wäre, um Reformen umzusetzen und einen modernen, am Staatsbürgerkonzept ausgerichteten Staat aufzubauen. Europa sollte eine Konsensfindung zwischen den Säkularen unterstützen, damit Tunesien international zukunftsfähig bleibt
