Background: Access to a comprehensive public health index or database has been identified as problematic for health professionals. Public health literature contains many varied sources including reports, journal articles, and grey literature. Traditional biomedical databases such as MEDLINE often do not meet the needs of public health workers and researchers.
Aim/methods: The aim of the study was to examine the unique content of the GLOBAL HEALTH database, by comparing it to the MEDLINE database. Pre-determined terms were used as baseline comparators where controlled vocabulary definitions in each database were sufficiently matched. Retrieved results were stored and compared using EndNote libraries.
Results: Results obtained from the terms used in the comparison study protocol suggest that the GLOBAL HEALTH database holds a high proportion of unique records in comparison to MEDLINE. The largest overlap of duplicates from the GLOBAL HEALTH database perspective came from the coccidiomycosis results set which contained 70.5% of references retrieved from both databases. Analyzing the results from a MEDLINE perspective, the subject with the largest overlap was dengue, with a 43% overlap.
Conclusion: The results of this study show that the GLOBAL HEALTH database is complimentary to MEDLINE in the subject areas of public health and global health.

Background: Pharmacoepidemiologic studies assessing drug effectiveness for Alzheimer's disease and related dementias (ADRD) are increasingly popular given the critical need for effective therapies for ADRD. To meet the urgent need for robust dementia ascertainment from real-world data, we aimed to develop a novel algorithm for identifying incident and prevalent dementia in claims.
Method: We developed algorithm candidates by different timing/frequency of dementia diagnosis/treatment to identify dementia from inpatient/outpatient/prescription claims for 6,515 and 3,997 participants from Visits 5 (2011-2013; mean age 75.
Background: In Alzheimer's Disease trials, the Mini-Mental State Examination (MMSE) and Clinical Dementia Rating (CDR) are commonly utilized as inclusionary criteria at screening. These measures, however, do not always reaffirm inclusionary status at baseline. Score changes between screening and baseline visits may imply potential score inflation at screening leading to inappropriate participant enrollment.

Background: Alzheimer's Disease (AD) poses a substantial global health burden, necessitating innovative therapeutic strategies. This study investigates the neuroprotective potential of a chrysin-loaded Nanostructured Lipid Carrier (NLC) drug delivery system in AD management. Employing the high-pressure homogenization method, chrysin-loaded NLCs were meticulously formulated to optimize drug delivery efficiency.

Background: Clinical trials should strive to yield results that are clinically meaningful rather than solely relying on statistical significance. However, the determination of clinical meaningfulness of dementia clinical trials lacks standardization and varies based on the trial's nature. To tackle this issue, a proposed approach involves assessing the time saved before reaching a specific threshold in cognitive status.

Merry Life Biomedical Company, Ltd., Tainan City, Taiwan, Taiwan.
Background: Alzheimer's disease (AD) is complex in pathogenesis and related to aging biology, especially in late-onset AD. We identified a novel synthetic curcumin analog TML-6 through the platform of 6 biomarkers of anti-aging, anti-inflammation, and anti-Aβ as the potential AD drug candidate. TML-6 exhibits multi-target effects on AD pathogenesis, including the activation of NrF-2, the regulation of autophagic machinery through mTOR, the inhibition of APP synthesis and reduction of Aβ, the upregulation of ApoE, and the inhibition of microglial activation.
