Brain Behav Immun 2017; 60:142-150. [PMID: 27742582 DOI: 10.1016/j.bbi.2016.10.004] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2016] [Revised: 09/06/2016] [Accepted: 10/08/2016] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND Infections represent the most frequent medical complications in stroke patients. Their main determinants are dysphagia and a transient state of immunodepression. We analyzed whether distinct anatomical brain regions were associated with the occurrence of stroke-associated infections or immunodepression. MATERIALS AND METHODS In 106 patients with acute ischemic stroke, we evaluated the incidence of pneumonia, urinary tract infection, or other infections together with the characterization of biomarkers of immunodepression. Twenty control subjects served to provide reference values. Using voxel-based lesion-symptom mapping, the involvement of gray and white matter structures was correlated with clinical and laboratory findings in crude analyses and in volume adjusted models to rule out associations reflecting differences in the size of the infarction. RESULTS Stroke-associated infection occurred in 22 (21%) patients and prevailed in patients with larger infarcts. Volume adjusted voxel-based lesion-symptom mapping revealed the involvement of the superior and middle temporal gyri, the orbitofrontal cortex, the superior longitudinal fasciculus and the inferior fronto-occipital fasciculus amongst infected patients. These associations were similar for pneumonia but not for urinary tract infections. Lymphopenia was associated with lesions of the superior and middle temporal gyri. Laterality did not influence stroke-associated infections or the presence of immunodepressive traits after volume control. The greatest overlap in the neuroanatomical correlates occurred between pneumonia and dysphagia. CONCLUSION Infarct volume plays a relevant role in the occurrence of stroke-associated infections, but lesions in specific brain locations such as the superior and lateral temporal lobe and the orbitofrontal cortex are also associated with increased infectious risk, especially pneumonia.

Abstract
In an attempt to find a new class antibacterial agents, a series of biscoumarins (1-4) and dihydropyrans (5-13) were successfully prepared. The molecular structures of four representative compounds, that is, 4, 5, 8 and 12 were confirmed by single crystal X-ray diffraction study. These synthesized compounds were screened for their antibacterial activity in vitro against Staphylococcus aureus (S. aureus ATCC 29213), methicillin-resistant S. aureus (MRSA XJ 75302), vancomycin-intermediate S. aureus (Mu50 ATCC 700699), USA 300 (Los Angeles County clone, LAC), Staphylococcus epidermidis (S. epidermidis ATCC 14990), methicillin-resistant S. epidermidis (MRSE XJ 75284) and Escherichia coli (E. coli ATCC 25922). Additionally, there are two classical intramolecular O-H···O hydrogen bonds (HBs) in biscoumarins 1-4 and the corresponding HB energies were further performed with the density functional theory (DFT) [B3LYP/6-31G*] method.

Abstract
Neurologists have a new toolbox of options for neurorehabilitation of disabling brain disorders such as stroke and traumatic brain injury. An emerging intellectual paradigm for neurologic recovery that includes neural regeneration, repair, and dynamic reorganization of functional neural systems, as well as increasing awareness of behavioral principles that may support best return to function and freedom, brought forward treatments based on experience-dependent learning, neurophysiologic stimulation, and a combination of these concepts. In this article, we summarize five rehabilitative approaches to watch: constraint therapy for motor and language recovery, synergy of motor-language rehabilitation, prism adaptation training and other virtual feedback approaches, and noninvasive magnetic and electrical brain stimulation.
