Migraine Characteristics, Comorbidities, Healthcare Resource Utilization, and Associated Costs of Early Users of Erenumab in the USA: A Retrospective Cohort Study Using Administrative Claims Data.

Introduction: Erenumab is indicated for migraine preventive treatment in adults. The objective of this study was to provide descriptive information on real-world use of erenumab including patient profile and treatment patterns.

Methods: We completed a retrospective review of US data (through May 2019) from the IBM MarketScan Early View Databases, identifying adult patients newly treated with erenumab with a migraine claim in the year prior to first erenumab claim (index) and at least 1 year of continuous pre-index medical and pharmacy insurance coverage, to assess pre- and post-erenumab migraine characteristics, comorbidities, healthcare resource utilization, and associated costs.

The migraine signature study: Methods and baseline results.

Objective: To characterize patients who utilize services for migraine in a large integrated health care network, and describe patterns of care and utilization.

Background: Within health care systems, migraine is a common reason for seeking primary and neurology care, but relatively little is documented about who seeks care and the factors that explain variation in utilization.

Methods: We conducted a retrospective cohort study using electronic health record (EHR) data from Sutter Health primary care (PC) patients who had at least one office visit to a PC clinic between 2013 and 2017.

A transgenic Alzheimer rat with plaques, tau pathology, behavioral impairment, oligomeric aβ, and frank neuronal loss.

Alzheimer's disease (AD) is hallmarked by amyloid plaques, neurofibrillary tangles, and widespread cortical neuronal loss (Selkoe, 2001). The "amyloid cascade hypothesis" posits that cerebral amyloid sets neurotoxic events into motion that precipitate Alzheimer dementia (Hardy and Allsop, 1991). Yet, faithful recapitulation of all AD features in widely used transgenic (Tg) mice engineered to overproduce Aβ peptides has been elusive.

The integrated proactive surveillance system for prostate cancer.

In this paper, we present the design and implementation of the integrated proactive surveillance system for prostate cancer (PASS-PC). The integrated PASS-PC is a multi-institutional web-based system aimed at collecting a variety of data on prostate cancer patients in a standardized and efficient way. The integrated PASS-PC was commissioned by the Prostate Cancer Foundation (PCF) and built through the joint of efforts by a group of experts in medical oncology, genetics, pathology, nutrition, and cancer research informatics.

Can peripheral leukocytes be used as Alzheimer's disease biomarkers?

Alzheimer's disease (AD) is the leading cause of dementia in elderly populations throughout the world and its incidence is on the rise. Current clinical diagnosis of AD requires intensive examination that includes neuropsychological testing and costly brain imaging techniques, and a definitive diagnosis can only be made upon postmortem neuropathological examination. Additionally, antemortem clinical AD diagnosis is typically administered following onset of cognitive and behavioral symptoms.

Better cognitive performance in elderly taking antioxidant vitamins E and C supplements in combination with nonsteroidal anti-inflammatory drugs: the Cache County Study.

Studies have shown less cognitive decline and lower risk of Alzheimer's disease in elderly individuals consuming either antioxidant vitamins or nonsteroidal anti-inflammatory drugs (NSAIDs). The potential of added benefit from their combined use has not been studied. We therefore analyzed data from 3,376 elderly participants of the Cache County Study who were given the Modified Mini-Mental State examination up to three times during a period of 8 years.

Blocking TGF-beta-Smad2/3 innate immune signaling mitigates Alzheimer-like pathology.

Alzheimer's disease is the most common dementia and is pathologically characterized by deposition of amyloid-beta peptide (Abeta) into beta-amyloid plaques, neuronal injury and low-level, chronic activation of brain immunity. Transforming growth factor-betas (TGF-betas) are pleiotropic cytokines that have key roles in immune cell activation, inflammation and repair after injury. We genetically interrupted TGF-beta and downstream Smad2/3 signaling (TGF-beta-Smad2/3) in innate immune cells by inducing expression of CD11c promoter-driven dominant-negative TGF-beta receptor type II in C57BL/6 mice (CD11c-DNR), crossed these mice with mice overexpressing mutant human amyloid precursor protein, the Tg2576 Alzheimer's disease mouse model, and evaluated Alzheimer's disease-like pathology.

Developing new treatments for Alzheimer's disease: the who, what, when, and how of biomarker-guided therapies.

This synthetic review presents an approach to the use of biomarkers for the development of new treatments for Alzheimer's disease (AD). After reviewing the process of translation as applied to AD, the paper provides a general update on what is known about the biology of the disease, and highlights currently available treatments. This is followed by a discussion of future drug development for AD emphasizing the roles that biomarkers are likely to play in this process: (1) define patients who are going to progress rapidly for the purpose of trial enrichment; (2) differentiate disease and therapeutically relevant AD subtypes; (3) assess the potential activity of specific therapies in vivo or ex vivo; and (4) measure the underlying disease state, so as to (a) detect disease and assess drug response in asymptomatic patients, (b) serve as a secondary outcome measure in clinical trials of symptomatic patients, and (c) decide if further development of a treatment should be stopped if not likely to be effective.

Cognitive function over time in the Alzheimer's Disease Anti-inflammatory Prevention Trial (ADAPT): results of a randomized, controlled trial of naproxen and celecoxib.

Background: Observational studies have shown reduced risk of Alzheimer dementia in users of nonsteroidal anti-inflammatory drugs.

Objective: To evaluate the effects of naproxen sodium and celecoxib on cognitive function in older adults.

Design: Randomized, double-masked chemoprevention trial.

NSAIDs for the chemoprevention of Alzheimer's disease.

Epidemiologic and laboratory studies suggest that non-steroidal anti-inflammatory drug (NSAID) use reduces the risk of Alzheimer's disease (AD). Initial reports in the early 1990's indicated that a history of arthritis, a presumed surrogate of NSAID use, was associated with a lower risk of AD. [1] These reports were followed by epidemiologic studies in which NSAID use was assessed directly and the majority of these reports confirmed the inverse association with risk for AD.

A population study of Alzheimer's disease: findings from the Cache County Study on Memory, Health, and Aging.

There are several population-based studies of aging, memory, and dementia being conducted worldwide. Of these, the Cache County Study on Memory, Health and Aging is noteworthy for its large number of "oldest-old" members. This study, which has been following an initial cohort of 5,092 seniors since 1995, has reported among its major findings the role of the Apolipoprotein E gene on modifying the risk for Alzheimer's disease (AD) in males and females and identifying pharmacologic compounds that may act to reduce AD risk.

Nonsteroidal anti-inflammatory drugs for the prevention of Alzheimer's disease: a systematic review.

Objective: Alzheimer's disease, the most prevalent dementia, is a prominent source of chronic illness in the elderly. Laboratory evidence suggests that nonsteroidal anti-inflammatory drugs (NSAIDs) might prevent the onset of Alzheimer's disease. Since the early 1990s numerous observational epidemiological studies have also investigated this possibility.
