This study investigates the anti-allergic properties of peanut skin polyphenols (PSP)-enriched peanut (PN) protein aggregates. PSP was blended with PN flour at concentrations of 5, 10, 15, 30, and 40% (w/w). Rat basophil leukemia cells (RBL-2H3) were sensitized with either anti-DNP-IgE or PN-allergic plasma followed by co-exposure to unmodified PN flour (control) or PSP-PN protein aggregates and Ca2+ ionophore, ionomycin. Immunoblotting and staining were performed to measure the IgE binding capacity of PSP-PN aggregates...

Inability to accurately diagnose Lewy type alpha-synucleinopathy (LTS) pre-mortem has been a major obstacle to clinical care and research. Probable REM sleep behavior disorder (PRBD) diagnosed with support of instruments such as the Mayo Sleep Questionnaire (MSQ) may provide a cost effective means of predicting LTS. Since 2007, 602 subjects in the Arizona Study of Aging and Neurodegenerative Disorders had clinician assessment for PRBD (298 with, 304 without support of the MSQ), completed cognitive and movement examinations, and had neuropathological assessment...

INTRODUCTION: Pseudoprogression (PsP) is a diagnostic dilemma in glioblastoma (GBM) after chemoradiotherapy (CRT). Magnetic resonance imaging (MRI) features may fail to distinguish PsP from early true progression (eTP), however clinical findings may aid in their distinction. METHODS: Sixty-seven patients received CRT for GBM between 2003 and 2016, and had pre- and post-treatment imaging suitable for retrospective evaluation using RANO criteria. Patients with signs of progression within the first 12-weeks post-radiation (P-12) were selected...

BACKGROUND: Differentiation of Parkinson's disease (PD) from the various types of atypical parkinsonism (AP) such as multiple system atrophy (MSA), progressive supranuclear palsy (PSP), dementia with Lewy bodies (DLB), corticobasal syndrome (CBS) and vascular parkinsonism (VP), can be challenging, especially early in the disease course when symptoms overlap. A major unmet need in the diagnostic workup of these disorders is a diagnostic tool that differentiates the various disorders, preferably in the earliest disease stages when the clinical presentation is similar...

Frontotemporal lobar degeneration (FTLD) is a clinically, pathologically, and genetically heterogeneous group of disorders that affect the frontal and temporal lobes of the brain. FTLD classification distinguishes three main neuropathological groups: FTLD-tau, FTLD-TDP, and FTLD-FUS. As a four-repeat tauopathy, argyrophilic grain disease (AGD) is included in the FTLD-tau group. AGD may also appear in association with other neuropathological disorders. We describe the demographic, clinical, neuropathological, and genetic characteristics of a series of FTLD cases presenting with AGD...

Religion is a form of coping that helps individuals to deal with a wide variety of difficult life situations. But most of the research in this field has been in acute patients of schizophrenia. Also, most of the research on religion and schizophrenia has focused on religion and spirituality as coping mechanisms, and research evaluating the relationship between spirituality/religiousness and repertoire of other coping skills is sparse. Our objective was to evaluate the association between spirituality, religiousness and coping skills in patients with schizophrenia in remission...

Objective: Parkinson's disease (PD) has significant clinical overlaps with atypical parkinsonism syndromes (APS), which have a poorer treatment response and a more aggressive course than PD. We aimed to identify plasma biomarkers to differentiate PD from APS. Methods: Plasma samples ( n = 204) were obtained from healthy controls and from patients with PD, dementia with Lewy bodies (DLB), multiple system atrophy, progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), or frontotemporal dementia (FTD) with parkinsonism (FTD-P) or without parkinsonism...

In a subset of glioblastoma (GBM) patients, the differentiation between tumor progression and tumor pseudoprogression (PsP) is challenging. This case describes a male patient suffering from isocitrate dehydrogenase 1 (IDH1) mutant GBM who demonstrated an increasing contrast-enhancing (CE) lesion on a cranial magnetic resonance imaging (cMRI) scan 8 months after radiochemotherapy. In accordance with the response assessment in neuro-oncology (RANO) criteria, the cMRI lesion was classified as recurrent tumor, although 18 F-fluoroethyl-L-tyrosine positron emission tomography (18 F-FET-PET) did not indicate vital tumor tissue...

BACKGROUND: Progressive Supranuclear Palsy (PSP) and Cortico-basal syndrome (CBS) may share similar clinical findings and peculiar tests to distinguish between the two disorders could be useful. We evaluated Blink Reflex (BR) and R2 Blink Reflex Recovery Cycle (R2BRRC), determining diagnostic sensitivity, specificity, positive and negative predictive value of R2BRRC in differentiating PSP from CBS patients. METHODS: This was a prospective data collection study investigating BR and R2BRRC at interstimulus intervals (ISIs) of 100, 150, 200, 300, 400, 500, 750 ms in 12 PSP patients, 8 CBS patients, and 10 controls...

INTRODUCTION: Adalimumab (ADA) is a medication used in the treatment of several autoimmune diseases. Despite the beneficial effects of ADA, its adherence and persistence rates are low. Patients treated with ADA from Clalit Health Services (CHS) can enroll in AbbVie's patient support program (PSP), which aims to improve ADA adherence and persistence. Therefore, we examine whether PSP participation is associated with a longer persistence and/or an improved adherence to ADA. METHODS: A real-world retrospective cohort study of all new ADA users from CHS, comparing those enrolled in the offered PSP to those not enrolled...

Introduction: Patients with prior primary spontaneous pneumothorax (PSP) frequently seek clearance to dive. Despite wide consensus in precluding compressed-air diving in this population, there is a paucity of data to support this decision. We reviewed the literature reporting the risk of PSP recurrence. Methods: A literature search was performed in PubMed and Web of Science using predefined terms. Studies published in English reporting the recurrence rate after a first PSP were included...

BACKGROUND AND OBJECTIVES: Gait impairment and reduced mobility are typical features of idiopathic Parkinson's disease (iPD) and atypical parkinsonian disorders (APD). Quantitative gait assessment may have value in the diagnostic workup of parkinsonian patients and as endpoint in clinical trials. The study aimed to identify quantitative gait parameter differences in iPD and APD patients using sensor-based gait analysis and to correlate gait parameters with clinical rating scales. SUBJECTS AND METHODS: Patients with iPD and APD including Parkinson variant multiple system atrophy and progressive supranuclear palsy matched for age, gender, and Hoehn and Yahr (≤3) were recruited at two Movement Disorder Units and assessed using standardized clinical rating scales (MDS-UPDRS-3, UMSARS, PSP-RS)...

The progressive supranuclear palsy is a progressive neurodegenerative disease characterized by Parkinsonism, oculomotor abnormalities, early postural instability and cognitive impairment. Neurodegeneration in PSP is associated with tau protein, but the mechanisms by which tau abnormalities lead to cell dysfunction and death are not well understood. Neuro-behavioural problems related to the fear and loss of autonomy can determinate many bioethical implications. Careful planning involving patients' families, academic and industry researchers were necessary to ensure improvement in quality of life...

The advent of the fully bioresorbable vascular scaffold (BVS) is the latest step in a series of advancements in the design of intracoronary stents over the past few decades. The novelty of this technology is in providing temporary vessel scaffolding and local antiproliferative therapy to prevent neointimal hyperplasia after percutaneous coronary intervention followed by gradual resorption of the scaffold to restore the native vessel anatomy and physiology-a process termed vascular reparative therapy. Areas covered: The first generation of BVS has not been able to fully match the high benchmark in safety and efficacy set by contemporary metallic drug-eluting stents...

BACKGROUND: Poor subpleural perfusion (PSP) in the capillary phase of pulmonary angiography predicts worse outcomes after pulmonary endarterectomy in operable chronic thromboembolic pulmonary hypertension (CTEPH). Balloon pulmonary angioplasty (BPA) has emerged for non-operable CTEPH. We assessed the association between PSP and BPA failure. METHOD: Subpleural perfusion was classified as poor (defined as subpleural spaces either not or minimally perfused in all segments) or normal...
