Editorial calls for more research on link between football and brain damage

Is brain damage an inevitable consequence of American football, an avoidable risk of it, or neither? An editorial published yesterday in the medical journal BMJ poses those provocative questions. Chad Asplund, director of sports medicine at Georgia Regents University, and Thomas Best, professor and chair of sports medicine at Ohio State University, offer an overview of the unresolved connection between playing football and chronic traumatic encephalopathy, a type of gradually worsening brain damage caused by repeated mild brain injuries or concussions. This condition was first described in a football player in 2005, after University of Pittsburgh experts performed an autopsy on Pittsburgh Steelers center Mike Webster, whose life had taken a downward turn after his retirement from professional football. Since then, researchers have linked chronic traumatic encephalopathy to the wasting away of brain tissue, the buildup of brain proteins linked to dementia and Alzheimer’s disease, memory loss, depression, anger, and other behavioral and emotional problems. So far, all cases of autopsy-proven chronic traumatic encephalopathy have been in players who sustained repeated blows to the head. That’s a fact of life for almost all professional football players. But some of those with the condition had never been diagnosed with a concussion. According to Asplund and Best, this suggests that a series of head injuries that don’t cause concussions may lead to chronic traum...

AbstractIntroductionMaternal perception of fetal movements has long been considered an indicator of fetal well ‐being. A sudden decrease in the number of fetal movements is suggestive of fetal compromise. We aimed to determine whether the maternal perception of reduced fetal movements (RFM) is associated with placental pathological lesions in a low‐risk term population.Material and methodsOur study was a case ‐control study that was performed in a single university center. Placental histopathology, maternal demographics, labor characteristics, and neonatal outcomes of term, singleton pregnancies with maternal percept...

This study aimed to analyse the features of lymphadenopathy and estimate the role of imaging methods, including computed tomography (CT) and positron emission tomography-CT (PET/CT), in the diagnosis of lymphadenopathy in patients with POEMS syndrome. We conducted a retrospective analysis of 23 patients with confirmed POEMS syndrome. All of the patients received chest and abdominal CT scan and/or superficial ultrasound examinations. Four patients underwent PET/CT examinations, and 6 patients received lymph node biopsies. Enlarged lymph nodes (short diameter ≥ 1 cm) were found in 48% (11/23) of patients, but only 1 patie...

UreñaAbstractThe effect of two types of graphene nanoplatelets on the curing kinetics, gelation and vitrification behaviour of a benzoxazine resin was investigated by means of differential scanning calorimetry and rheological experiments. The results showed that the incorporation of graphene nanoplatelets did not change the autocatalytic nature of curing reaction. However, when benzoxazine was doped with the nanofiller supplied by XG-Scien...

This study focuses on the synthesis of lithium aluminate material. The obtained γ-LiAlO2 material for application in radiation dosimetry is reported. γ-LiAlO2 powder was prepared by a sol-gel approach and a solid state reaction method for comparison purpose. The lithium aluminate was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that LiAlO2 powder has a crystalline structure in the gamma- phase form depending strongly on calcined temperature. Both methods produced completely pure γ-LiAlO2 with the average density of 2.615g/cm3 at a relatively low tempe...
