Pooling data from past trials may help identify subgroups most likely to benefit from specific treatments and thus inform future trial design. In this perspective, we report on our effort to pool data from past Alzheimer's disease trials to identify patients most likely to respond to different treatments. We delineate challenges and hurdles, from our proof-of-principle study, for which we requested access to trial datasets from various pharmaceutical companies and encountered obstacles in the process of arranging data-sharing agreements through legal departments. Six phase I–III trials from three sponsors provided access to their data (total <i>n</i> = 3170), which included demographic information, vital signs, primary and secondary endpoints, and in a small subset, cerebrospinal fluid amyloid (<i>n</i> = 165, 5.2%) and tau (<i>n</i> = 212, 6.7%). Data could be analyzed only within specific data access platforms, limiting potential harmonization with data provided through other platforms. Limited overlap in terms of outcome measures, clinical and biological information hindered analyses. Thus, while it is a commendable advancement that (some) trials now allow researchers to study their data, we conclude that gaining access to past trial datasets is complicated, frustrating the field's communal effort to find the best treatments for the right individuals. We provide a plea to promote harmonization and open access to data, by urging trial sponsors and the academic research community alike to remove barriers to data access and improve collaboration through practicing open science and harmonizing outcome measures, to allow investigators to learn all there is to learn from past failures and successes.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> HIGHLIGHTS</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Pooling data from past Alzheimer's disease clinical trials may help identify subgroups most likely to benefit from specific treatments and may help inform future trial design.</li>\u0000 \u0000 <li>Accessing past trial datasets is complicated, frustrating the field's communal effort to find the best treatments for the right individuals.</li>\u0000 \u0000 <li>We urge trial sponsors and the academic research community to remove data access barriers and improve collaboration through practicing open science and harmonizing outcome measures.</li>\u0000 </ul>\u0000 </div>\u0000 </section>\u0000 </div>","PeriodicalId":53225,"journal":{"name":"Alzheimer''s and Dementia: Translational Research and Clinical Interventions","volume":"10 3","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11303826/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141903598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is a lack of consensus on how to measure it and this limits ability to find what improves and impairs social connection in LTC homes. We therefore aimed to systematically review and evaluate the measurement properties of existing measures of social connection for LTC residents, to identify which, if any, measures can be recommended. We searched eight electronic databases from inception to April 2022 for studies which reported on psychometric properties of a measure of any aspect(s) of social connection (including social networks, interaction, engagement, support, isolation, connectedness, and loneliness) for LTC residents. We used COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines to evaluate the measurement properties reported for each identified measure and make recommendations. We identified 62 studies reporting on 38 measures; 21 measured quality of life, well-being or life satisfaction and included a social connection subscale or standalone items and 17 measures specifically targeted social connection. We found there was little high-quality evidence on psychometric properties such as sufficient content validity (<i>n</i> = 0), structural validity (<i>n</i> = 3), internal consistency (<i>n</i> = 3), reliability (<i>n</i> = 1), measurement error (<i>n</i> = 0), construct validity (<i>n</i> = 4), criterion validity (<i>n</i> = 0) and responsiveness (<i>n</i> = 0). No measures demonstrated satisfactory psychometric properties on all these aspects, so none could be recommended for use. Thirty-four measures have the potential to be recommended but require further research to assess their quality and the remaining four are not recommended for use. Our review therefore found that no existing measures have sufficient evidence to be recommended for assessment of social connection in residents of LTC homes. Further validation and reliability studies of existing instruments or the development of new measures are needed to enable accurate measurement of social connection in LTC residents for future observational and interventional studies.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Highlights</h3>\u0000 \u0000 <div>\u0000 <ul>\u0000 \u0000 <li>Social connection is fundamental to person-centered care in long-term care homes.</li>\u0000 \u0000 <li>There is insufficient evidence for the reliability and validity of existing measures.</li>\u0000 \u0000 <li>No current measures can be recommended for use based on existing evidence.</li>\u0000 \u0000 <li>A reliable and valid measure of social connection is needed for fu","PeriodicalId":53225,"journal":{"name":"Alzheimer''s and Dementia: Translational Research and Clinical Interventions","volume":"10 3","pages":""},"PeriodicalIF":4.9,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11299077/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141894860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In regions beyond temporal cortex, tau PET uptake decreased with age for the same pTau-181 or GFAP concentrations. FDG PET and brain volumes correlate with tau PET in numerous regions (such as inferior temporal: <i>p</i> = 0.0007, <i>p</i> = 0.00001, respectively). NfL, GFAP, and all imaging modalities correlate with baseline MMSE; subsequent MMSE decline is predicted by baseline parahippocampal and lateral temporal tau PET (<i>p</i> = 0.0007) and volume (<i>p</i> = 0.0006). Lateral temporal FDG PET (<i>p</i> = 0.006) and volume (<i>p</i> = 0.0001) are most strongly associated with subsequent ADAS-cog decline.
