Caregivers' Perceptions of Clinical Symptoms, Disease Management, and Quality of Life Impact in Cases of Cyclin-Dependent Kinase-Like 5 Deficiency Disorder: Cross-Sectional Online Survey.

Background: Cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) is an ultrarare genetic condition causing developmental epileptic encephalopathy characterized by seizures and motor and intellectual disabilities. No disease-modifying therapies are available, and treatments focus mainly on symptom management to improve quality of life.

Objective: The aim of this study was to better understand the burden of CDD based on family caregivers' perceptions.

Measuring the Burden of Epilepsy Hospitalizations in CDKL5 Deficiency Disorder.

Background: Information on the hospital service use among individuals with CDKL5 Deficiency Disorder, an ultrarare developmental epileptic encephalopathy, is limited, evidence of which could assist with service planning. Therefore, using baseline and longitudinal data on 379 genetically verified individuals in the International CDKL5 Disorder Database, we aimed to investigate rates of seizure-related and other hospitalizations and associated length of stay in this cohort.

Methods: Outcome variables were lifetime count of family-reported hospitalizations and average length of stay both for seizure- (management and/or investigative) and non-seizure-related causes.

Erenumab Decreases Headache-Related Sick Leave Days and Health Care Visits: A Retrospective Real-World Study in Working Patients with Migraine.

Introduction: The prevalence of migraine is highest among working age individuals, and this disease is associated with an increased number of sick leaves and health care visits, as well as lost productivity. Erenumab, the first monoclonal antibody targeting the calcitonin gene-related peptide (CGRP) pathway, is effective in decreasing the monthly number of migraine days, but evidence of its impact on the number of sick leave days and health care visits in patients with migraine is limited.

Methods: This retrospective registry study focused on occupationally active patients with migraine treated with erenumab at a Finnish private health care provider, Terveystalo.

My Migraine Voice survey: disease impact on healthcare resource utilization, personal and working life in Finland.

Background: A global My Migraine Voice survey was conducted in 31 countries among 11,266 adults who suffered from ≥4 monthly migraine days (MMD). The aim of this retrospective observational survey-based study was to analyse the country specific results in Finland in order to understand the impact of migraine based on disease severity.

Methods: The included participants (3%, n = 338/11,266) were stratified by mean MMDs into 4 ≤ MMD < 8 (n = 133), 8 ≤ MMD < 15 (n = 139) and MMD ≥ 15 (n = 66) subgroups.

Burden of migraine in Finland: multimorbidity and phenotypic disease networks in occupational healthcare.

Background: Migraine is a complex neurological disorder with high co-existing morbidity burden. The aim of our study was to examine the overall morbidity and phenotypic diseasome for migraine among people of working age using real world data collected as a part of routine clinical practice.

Methods: Electronic medical records (EMR) of patients with migraine (n = 17,623) and age- and gender matched controls (n = 17,623) were included in this retrospective analysis.

Burden of migraine in Finland: health care resource use, sick-leaves and comorbidities in occupational health care.

Background: The highest prevalence of migraine is detected among people who are of working age. The aim of this study was to assess the burden of migraine in an occupational health care setting using real world data collected as a part of routine clinical practice.

Methods: This retrospective register study included migraineurs using occupational health care at the private health care provider Terveystalo.

Poly(ADP-ribose) polymerase-1 regulates microglia mediated decrease of endothelial tight junction integrity.

Alzheimer's disease pathology includes, beside neuronal damage, reactive gliosis and reduced blood-brain barrier (BBB) integrity. Microglia are intimately associated with the BBB and upon AD pathology, pro-inflammatory responses of microglia could contribute to BBB damage. To study whether microglia can directly affect BBB integrity, the effects of amyloid beta (Aβ) -stimulated primary murine microglia on co-cultured mouse brain endothelial cells (bEnd3) and murine astrocyte cultures were assessed.

Interleukin-18 alters protein expressions of neurodegenerative diseases-linked proteins in human SH-SY5Y neuron-like cells.

Chronic inflammation and oxidative stress (OS) are present in Alzheimer's disease (AD) brains in addition to neuronal loss, Amyloid-β (Aβ) plaques and hyperphosphorylated tau-protein neurofibrillary tangles (NFTs). Previously we showed that levels of the pro-inflammatory cytokine, interleukin-18 (IL-18), are elevated in post-mortem AD brains. IL-18 can modulate the tau kinases, Cdk5 and GSK3β, as well as Aβ-production.

An update on clinical proteomics in Alzheimer's research.

Alzheimer's disease (AD) is a pathologically complex and aetiologically multifactorial dementing disorder affecting millions of people worldwide. The pathological brain changes are assumed to occur decades prior to the onset of clinical symptoms. The diagnosis of early AD remains problematic and is mainly based on clinical and neuropsychological findings after the onset of symptoms.

3rd Annual FinnProt Meeting: from cells to systems.

The Finnish Proteomics Society, FinnProt ( www.finnprot.org ), was founded in November 2004 as the Proteomics Division of the Societas biochemica, biophysica et microbiologica Fenniae ( www.

Multiplexed proteomic analysis of oxidation and concentrations of cerebrospinal fluid proteins in Alzheimer disease.

Background: Carbonylation is an irreversible oxidative modification of proteins that has been linked to various conditions of oxidative stress, aging, physiological disorders, and disease. Increased oxidative stress is thus also considered to play a role in the pathogenesis of age-related neurodegenerative disorders such as Alzheimer disease (AD). In addition, it has recently become evident that the response mechanisms to increased oxidative stress may depend on sex.

Oxidative modification of proteins in the frontal cortex of Alzheimer's disease brain.

There is a large body of evidence highlighting the importance of oxidative stress in the pathogenesis of Alzheimer's disease (AD). We have previously standardised a method that can be applied to study oxidative changes in individual brain proteins by using two-dimensional oxyblots (Korolainen MA, Goldsteins G, Alafuzoff I, Koistinaho J, Pirttilä T. Proteomic analysis of protein oxidation in Alzheimer's disease brain.

Proteomic analysis of glial fibrillary acidic protein in Alzheimer's disease and aging brain.

Chronic inflammation is known to play an important role in the heterogeneous pathogenesis of Alzheimer's disease (AD). Activated astrocytes expressing glial fibrillary acidic protein (GFAP) are closely associated with AD pathology, such as tangles, neuritic plaques and amyloid depositions. Altogether, 46 soluble isoforms of GFAP were separated and most of them quantified by two-dimensional immunoblotting in frontal cortices of AD patients and age-matched controls.

Proteomic analysis of protein oxidation in Alzheimer's disease brain.

There is a growing body of evidence that oxidative stress plays a major role in Alzheimer's disease (AD) pathogenesis. Identification of oxidatively altered proteins in AD is important for understanding the relationship between protein oxidation, protein aggregation and neurodegeneration. In this communication, we report a method that can be applied to study oxidative changes of individual proteins in brain.
