BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, affecting 2.5 million people globally and 400,000 people in the United States. While no cure exists for MS, the goal is to manage the disease using disease-modifying therapies (DMTs), which have been shown to slow disease progression and prevent relapses. Relapsing-remitting MS (RRMS) is the most common form of MS at the time of diagnosis. Peginterferon beta-1a (PEG) and alemtuzumab (ALT) were recently approved and have demonstrated good clinical outcomes, including reduced relapse rates in clinical trials...

Michael F Holick
Vitamin D deficiency and insufficiency is a global health issue that afflicts more than one billion children and adults worldwide. The consequences of vitamin D deficiency cannot be under estimated. There has been an association of vitamin D deficiency with a myriad of acute and chronic illnesses including preeclampsia, childhood dental caries, periodontitis, autoimmune disorders, infectious diseases, cardiovascular disease, deadly cancers, type 2 diabetes and neurological disorders. This review is to put into perspective the controversy surrounding the definition for vitamin D deficiency and insufficiency as well as providing guidance for how to treat and prevent vitamin D deficiency...

REVIEW
Ellen Tedford, Glenn McConkey
Although the parasite Toxoplasma gondii is one of the most pervasive neurotropic pathogens in the world, the host-parasite interactions during CNS infection and the consequences of neurological infection are just beginning to be unraveled. The chronic stages of infection have been considered dormant, although several studies have found correlations of infection with an array of host behavioral changes. These may facilitate parasite transmission and impact neurological diseases. During infection, in addition to the presence of the parasites within neurons, host-mediated neuroimmune and hormonal responses to infection are also present...

BACKGROUND: Protein O-linked-β-N-acetyl glucosamine (O-GlcNAc) is a post-translational modification to Ser/Thr residues that integrates energy supply with demand. Abnormal O-GlcNAc patterning is evident in several neurological disease states including epilepsy, Alzheimer's disease and autism spectrum disorder (ASD). A potential treatment option for these disorders includes the high-fat, low-carbohydrate, ketogenic diet (KD). The goal of this study was to determine whether the KD induces changes in O-GlcNAc in the BTBR(T+tf/j) (BTBR) mouse model of ASD...

AbstractFlea-borne (murine) typhus is a global rickettsiosis caused by Rickettsia typhi. Although flea-borne typhus is no longer nationally notifiable, cases are reported for surveillance purposes in a few U.S. states. The infection is typically self-limiting, but may be severe or life-threatening in some patients. We performed a retrospective review of confirmed or probable cases of fatal flea-borne typhus reported to the Texas Department of State Health Services during 1985-2015. When available, medical charts were also examined...

Patients with unclear patterns of developmental and cognitive delay may go years without a definitive diagnosis despite extensive testing due to overlapping phenotypes of many genetic disorders. In this study, we identified causative variants in DYRK1A, KARS, or KAT6A in four individuals with global developmental delay and various findings including microcephaly and sensorineural hearing loss using whole exome sequencing. We present the cognitive, neurologic, and physical findings of four individuals to expand the clinical knowledge of possible features of the phenotypes of three rare genetic disorders...

Cardiac arrest-induced global cerebral ischemia injury (CA-GCII) usually leads to a poor neurological outcome without an effective treatment. Bone marrow-derived mesenchymal stem cells (BMMSCs) may provide a potential cell-based therapy against neurologic disorders through induction of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF). To optimize the neuroprotective efficacy of BMMSCs further, in this study we have derived BMMSCs, which co-overexpress both BDNF and VEGF, and tested them for the treatment of CA-GCII in a rat model...

OBJECTIVE: Transcranial Magnetic Stimulation in de novo patients with Celiac Disease previously revealed an imbalance in the excitability of cortical facilitatory and inhibitory circuits. After a median period of 16 months of gluten-free diet, a global increase of cortical excitability was reported, suggesting a glutamate-mediated compensation for disease progression. We have now evaluated cross-sectionally the changes of cortical excitability to TMS after a much longer gluten-free diet...

Global expression profiling of neurologic or psychiatric disorders has been confounded by variability among laboratories, animal models, tissues sampled, and experimental platforms, with the result being that few genes demonstrate consistent expression changes. We attempted to minimize these confounds by pooling dentate granule cell transcriptional profiles from 164 rats in seven laboratories, using three status epilepticus (SE) epilepsy models (pilocarpine, kainate, self-sustained SE), plus amygdala kindling...

Failure of the blood-brain barrier (BBB) is a critical event in the development and progression of diseases such as acute ischemic stroke, chronic ischemia or small vessels disease that affect the central nervous system. It is not known whether BBB breakdown in subjects with chronic carotid artery stenosis can be restrained with postoperative recovery of cerebral perfusion. The aim of the study was to assess the short-term effect of internal carotid artery stenting on basic perfusion parameters and permeability surface area-product (PS) in such a population...

Falling is a major problem among the people globally, frequently due to some health problems including vision loss or balance disorder as a consequence of aging. As a result of the falling in elder people; injuries, complications, neurological problems and mortality are generally occurred. This situation also affects the patients' families psychologically. A large number of studies show that significant fractures, injuries and in some cases death are commonly encountered in elderly. Nonetheless, in the immediate intervention, the rate of damage is reduced and the life quality can be significantly restored...

We support the findings of Carmody et al. [1], who offered new insights into the neurological phenotype of people with KCNJ11 neonatal diabetes. Neurological features result from the KATP channel affected by these mutations being expressed in the brain as well as the pancreas [2]. Previous work has characterized developmental delay associated with specific mutations, for example, V59M, known as developmental delay, epilepsy and neonatal diabetes (DEND) syndrome [3,4]. Affected individuals also have impaired visuo-motor performance [5] and psychiatric (predominantly neurodevelopmental) disorders [6]...

BACKGROUND: Measures of chest compression fraction (CCF), compression rate, compression depth and pre-shock pause have all been independently associated with improved outcomes from out-of-hospital (OHCA) cardiac arrest. However, it is unknown whether compliance with American Heart Association (AHA) guidelines incorporating all the aforementioned metrics, is associated with improved survival from OHCA. METHODS: We performed a secondary analysis of prospectively collected data from the Resuscitation Outcomes Consortium Epistry-Cardiac Arrest database...

BACKGROUND: Neuronal primary cilia are sensory organelles that are critically involved in the proper growth, development, and function of the central nervous system (CNS). Recent work also suggests that they signal in the context of CNS injury, and that abnormal ciliary signaling may be implicated in neurological diseases. METHODS: We quantified the distribution of neuronal primary cilia alignment throughout the normal adult mouse brain by immunohistochemical staining for the primary cilia marker adenylyl cyclase III (ACIII) and measuring the angles of primary cilia with respect to global and local coordinate planes...
