Atrophy patterns on MRI can reliably predict three neuropathological subtypes of Alzheimer's disease (AD): typical, limbic-predominant, or hippocampal-sparing. A method to enable their investigation in the clinical routine is still lacking. We aimed to (1) validate the combined use of visual rating scales for identification of AD subtypes; (2) characterise these subtypes at baseline and over two years; and (3) investigate how atrophy patterns and non-memory cognitive domains contribute to memory impairment...

Nowadays, there is a lot of interest in assessing functional interactions between key brain regions. In this paper, Granger causality analysis (GCA) and motif structure are adopted to study directed connectivity of brain default mode networks (DMNs) in resting state. Firstly, the time series of functional magnetic resonance imaging (fMRI) data in resting state were extracted, and the causal relationship values of the nodes representing related brain regions are analyzed in time domain to construct a default network...

Few studies have evaluated magnetic resonance imaging (MRI) visual scales in Parkinson's disease-Mild Cognitive Impairment (PD-MCI). We selected 79 PD patients and 92 controls (CO) to perform neurologic and neuropsychological evaluation. Brain MRI was performed to evaluate the following scales: Global Cortical Atrophy (GCA), Fazekas, and medial temporal atrophy (MTA). The analysis revealed that both PD groups (amnestic and nonamnestic) showed worse performance on several tests when compared to CO. Memory, executive function, and attention impairment were more severe in amnestic PD-MCI group...

The objective of the study was to assess the quality of life (QOL) of patients with giant cell arteritis (GCA), following high dose of corticosteroids (CS). Thirty patients with GCA who had stopped CS or who were under long-term low dose of CS were included and matched to 60 controls. QOL was measured by the SF-36 score and a specific questionnaire. GCA patients had no impairment of QOL compared to controls according to SF-36. Most of them (57%) estimated that their general condition was improved following treatment...

Age-related brain atrophy is a common finding, but neurodegenerative diseases such as Alzheimer's disease are associated with accelerated atrophy of the medial temporal lobe. In current practice for brain atrophy evaluation, several rating scales are being used such as the medial temporal atrophy (MTA), global cortical atrophy-frontal subscale (GCA-F) and posterior atrophy (PA) scales. Practical cut-offs to differentiate between normal and advanced brain atrophy are needed, because of their possible usefulness as a biomarker...

Alanine is encoded by the four codons of the GC box (GCA, GCG, GCU, and GCC). Known alanine anticodons include the UGC, IGC, and VGC triplets (I = inosine; V = uridine-5-oxyacetic acid). The energy-minimized structures of all possible codon-anticodon combinations involving all the alanine codons GCA, GCG, GCU, and GCC with the alanine anticodons UGC, IGC, and VGC are studied using the AMBER software. Fifteen H-bonded duplex structures arising out of these combinations are studied here, all having Watson-Crick-type base pairs at the first and second codon positions, and a variety of base pairing possibilities at the third (or wobble) position...

Gingival cysts, which are more frequently reported as gingival cysts of adults (GCA), are soft tissue cystic lesions of odontogenic origin that are infrequently seen, especially in children. These lesions usually appear as localized firm elevations on the facial gingiva in the anterior segment of the mandible. The purpose of this paper is to present a rare case of a gingival cyst discovered on the palatal aspect of the posterior maxilla in a four-year-old child. The lesion was treated with excisional biopsy...

Giant cell arteritis (GCA) is a systemic autoimmune disease that affects medium- and large-sized arteries. The diagnostic gold standard is the temporal artery biopsy, but it has limited sensitivity and some difficulties in reproducibility. Color duplex ultrasonography is a noninvasive, reproducible, and inexpensive method for diagnosis of temporal arteries involvement (temporal arteritis [TA]) in GCA with high sensitivity and specificity. We present the ultrasound findings at baseline and during follow-up in a case of TA in a patient with GCA...

Maternally expressed gene 3 (MEG3) is an imprinted gene located at 14q32 which encodes an lncRNA and is downregulated in an expanding list of cancer cell lines and primary human cancers. The miR-770 is transcribed from the intronic sequence of MEG3 and MEG3 may be the host gene for miR-770. However, the biological role of MEG3 and miR-770 in gastric cardia adenocarcinoma (GCA) development and prognosis is poorly defined. The present study was to investigate the function and methylation status of MEG3 in GCA, and further to detect the functional association of miR-770 and its host gene MEG3 in GCA carcinogenesis and prognosis...

OBJECTIVES: Outcome assessment in large-vessel vasculitis (LVV) remains challenging and this impairs patient management and the conduct of clinical studies. Previous proposals for outcome tools have not included imaging. This study aimed to develop an imaging score to quantify damage in LVV and to assess the difference between Takayasu (TAK) and giant cell arteritis (GCA). METHODS: Ninety-six patients (41 TAK, 55 GCA) were identified from local registries at two University Hospitals in the UK...

Nowadays noninvasive vascular imaging has an important role in the diagnostic work-up of the large vessel vasculitides (LVV), most importantly giant cell arteritis (GCA) and Takayasu arteritis. Among the imaging modalities available, ultrasound (US) has several important advantages, including low costs, rapid and repetitive availability without exposure to radiation, and high spatial resolution for assessment of large and medium-sized arteries. Therefore, US can be regarded the first line imaging method in suspected LVV...

Valeria Silvestri, Giacomo Isernia
Giant cell arteritis (GCA) is an inflammatory vasculopathy affecting large- and middle-sized vessels, specifically cranial arteries derived from carotid artery. Isolated extracranial vessel involvement can occur. Interest in extravascular manifestations is recently increasing because of diffusion of sensitive and specific imaging tools such as fluorodeoxyglucose positron emission tomography computerized tomography (18 FDG PET CT). Patients have an increased relative risk of severe infection. Listeria monocytogenes infection risk is increased, and vascular system involvement and graft infection have been, although rarely, reported...

BACKGROUND: Giant cell arteritis (GCA) is a form of large-vessel vasculitis affecting patients older than 50years old. Recent reports have suggested that the condition is caused by reactivation of varicella zoster virus (VZV). If that is indeed the case, a vaccine that prevents VZV reactivation should reduce the incidence of GCA. To further test that hypothesis, we assessed the incidence of GCA among patients older than 50years of age who were vaccinated against VZV and compared it to GCA incidence in the general population...
