Vascular dementia (VaD), the second most common cause of cognitive impairment in the population, is a disease that results from reduction in regional cerebral blood flow and involves oxidative stress and inflammation. Co-ultramicronized PEALut (co-ultra PEALut) is a new compound with beneficial effects, which include anti-inflammatory and antioxidant properties. Recently, co-ultraPEALut has been shown to exhibit neuroprotective effects in models of Parkinson's disease, cerebral ischemia and Alzheimer's disease...

Background: the diagnosis of cerebral small vessel disease, a leading cause of vascular dementia (VaD), relies solely on neuroimaging studies. Circulating microRNAs (miRNAs) have been proposed as diagnostic biomarkers in various disorders. Our aim was to identify differentially expressed, circulating miRNAs in small vessel VaD which could serve as diagnostic biomarkers for this disease. Method: we performed plasma miRNA profiling by quantitative polymerase chain reaction (qPCR) array in small vessel VaD patients and age- and gender-matched, cognitively normal and healthy controls...

Cardanol monoene (CM) is the major phenolic component extracted from cashew nut shell liquid (CNSL), which has been relevant to wide range of biological effects. In this study, we found that CM could inhibit the M14 human melanoma cells proliferation in a dose dependent and time dependent manner, and the IC50 values were determined to be 23.15 ± 2.42 μM and 12.30 ± 1.67 μM after 24 h and 48 h treatment, respectively. The flow cytometric analysis demonstrated that CM induced M14 cell cycle arrest at S phase, along with the collapse of mitochondrial membrane potential (ΔΨm) and the accumulation of reactive oxygen species (ROS) level in cells,but the apoptotic cells reduced when treated with Z-VAD-FMK (pan-caspase inhibitor)...

Arnaoutoglou et al. (2017) reported that "Ishihara Color Vision Test - 38 Plate" was useful for the differential diagnosis of dementia between Alzheimer's Disease (AD) and Vascular Dementia (VaD). The authors used sensitivity/specificity analysis, presenting 80.6% and 87.5% to discriminate AD and VaD patients when an optimal (32.5) cut-off value of performance was used. The authors cited a reference of the fact that AD patients suffered from a non-specific type of color blindness (Pache et al., 2003), and I have a query on their study with special reference to statistical method...

The aim of this work is to study pediatric pneumatic ventricle (PVAD) performance, versus VAD rate (VADR) and native heart rate (HR) ratio Rr (VADR/HR). The study uses a hybrid model of the cardiovascular system (HCS). HCS consists of a computational part (a lumped parameter model including left and right ventricles, systemic and pulmonary arterial and venous circulation) interfaced to a physical part. This permits the connection of a VAD (15 mL PVAD). Echocardiographic and hemodynamic data of a pediatric patient (average weight 14...

OBJECTIVE: A workgroup of clinical experts has developed an Appropriate Use Criteria (AUC) for the use of hyaluronic acid (HA) in the treatment of osteoarthritis (OA) of the knee. The increasingly broad and varied use of HA injections, lack of published clinical guidance, and limited coverage for their use has created the imperative to establish appropriateness criteria. METHODS: The experts of this workgroup represent rheumatology, orthopedic surgery, physiatry, sports medicine, and nursing clinicians with substantive knowledge of intra-articular HA therapy...

Ventricular assist devices (VADs) have positively impacted the management of heart failure. However, they come with a range of complications. Although general surgical complications have been assessed in adults with VADs, there is no study to date that has assessed general surgery intervention in the pediatric population. Fifty-two patients who received VADs from 2005 to 2015 at the Stollery Children's Hospital were assessed for general surgery intervention and anticoagulation status at the time of intervention...

Background: The accurate estimation of the prevalence of vitamin A deficiency (VAD) is important in planning and implementing interventions. Retinol-binding protein (RBP) is often used in population surveys to measure vitamin A status, but its interpretation is challenging in settings where inflammation is common because RBP concentrations decrease during the acute-phase response.Objectives: We aimed to assess the relation between RBP concentrations and inflammation and malaria in preschool children (PSC) (age range: 6-59 mo) and women of reproductive age (WRA) (age range: 15-49 y) and to investigate adjustment algorithms to account for these effects...

BACKGROUND: Stroke is the most feared complication associated with the Berlin Heart EXCOR pediatric ventricular assist device (VAD), the most commonly used VAD in children, and affects 1 in 3 children. We sought to determine whether a modified anti-thrombotic guideline, involving more intense platelet inhibition and less reliance on platelet function testing, is associated with a lower incidence of stroke. METHODS: All children supported with the EXCOR at Stanford from 2009 to 2014 were divided into 2 cohorts based on the primary anti-thrombotic guideline used to prevent pump thrombosis: (1) the Edmonton Anti-thrombotic Guideline (EG) cohort, which included children implanted before September 2012 when dual anti-platelet therapy was used with doses titrated to Thromboelastrography/PlateletMapping (TEG/PM); and (2) the Stanford Modified Anti-thrombotic Guideline (SG) cohort, which included children implanted on or after September 2012 when triple anti-platelet therapy was used routinely and where doses were uptitrated to high, weight-based dosing targets, with low-dose steroids administered as needed for inflammation...

Pump thrombosis represents a significant cause of morbidity and mortality in patients on continuous flow ventricular assist devices (CF-VAD). Pump thrombosis in the pediatric CF-VAD population has been reported between 11% and 44%, with the largest reported series from the PediMACS registry reporting a rate of approximately 15%. We report our early experience with four pediatric patients who developed pump thrombosis on a CF-VAD. Our limited experience suggests that the treatment of pediatric VAD thrombosis can be approached with similar principles to the adult population...

Here we describe the case of a 62-year-old woman diagnosed with multiple myeloma (IgA-κ type) who had a high serum CEA level of 27.7 ng/ml. Upper and lower gastrointestinal endoscopy and PET/CT scan showed no abnormality. After two courses of VAD therapy, the serum CEA level decreased to 5.7 ng/ml, with a decrease in the IgA level, suggesting the diagnosis of CEA-producing myeloma. After 4 years and 1 month, she had a relapse with an increase in the LDH level and myeloma cells in the blood, followed by cognitive loss and convulsion...

The pediatric use of pneumatic ventricular assist devices (VADs) as a bridge to heart transplant still suffers for short-term major complications such as bleeding and thromboembolism. Although numerical techniques are increasingly exploited to support the process of device optimization, an effective virtual benchmark is still lacking. Focusing on the 12 cc Penn State pneumatic VAD, we developed a novel fluid-structure interaction (FSI) model able to capture the device functioning, reproducing the mechanical interplay between the diaphragm, the blood chamber, and the pneumatic actuation...

Alterations in the immune response that result in inflammation might play a role in the pathology of dementias. In order to analyze changes of the peripheral immune system associated with different types of dementias, we determined several innate and adaptive cell populations in whole blood using flow cytometry. We included patients with Alzheimer's disease (AD; n = 60), vascular dementia (VaD; n = 20), and frontotemporal dementia (FTD; n = 12) at the time point of diagnosis and 24 age-matched neuropsychiatric healthy persons...
