Medication for Alzheimer’s Disease and Associated Fall Hazard: a Retrospective Cohort Study from the Alzheimer’s Disease Neuro-Imaging Initiative

BACKGROUND: Falls are common in the elderly, especially in those with cognitive impairment. The elderly are often treated with several medications, which may have both beneficial and deleterious effects. The use and type of medication in Alzheimer's disease (AD) patients and association with falls is limited. OBJECTIVE: We examined the association between falls and medication use in the Alzheimer's Disease Neuroimaging Initiative (ADNI). METHODS: Diagnosis, demographics, medication use, apolipoprotein E4 allele status and functional activity level at baseline were gathered for 810 participants enrolled in the ADNI, including healthy controls and subjects with mild cognitive impairment or Alzheimer's. Reports detailing adverse event falls were tabulated. Baseline characteristics were compared between subjects with and without one or more falls. Cox proportional hazards models were conducted to evaluate the association between subject characteristics and hazard of the first fall. RESULTS: Age (p < 0.0001), Functional Activities Questionnaire (p = 0.035), Beers List (p = 0.0477) and medications for treating cognitive symptoms of Alzheimer's (p = 0.0019) were associated with hazard of fall in the univariate model. In the final multivariate model, after adjusting for covariates, Alzheimer's medication use (p = 0.0005) was associated with hazard of fall. Medication was changed by the clinician after an adverse fall event in 9% of the falls. About 7% of the falls were reported as serious adverse events and 6% were reported to be severe. CONCLUSION: We found a significant association between the use of symptomatic medication treating cognitive symptoms in AD and hazard of fall after adjusting for age and Beers List medication use. Additional pharmacovigilance of the association between falls and Alzheimer's medication use is warranted

Expanded encyclopaedias of DNA elements in the human and mouse genomes

All data are available on the ENCODE data portal: www.encodeproject. org. All code is available on GitHub from the links provided in the methods section. Code related to the Registry of cCREs can be found at https:// github.com/weng-lab/ENCODE-cCREs. Code related to SCREEN can be found at https://github.com/weng-lab/SCREEN.© The Author(s) 2020. The human and mouse genomes contain instructions that specify RNAs and proteins and govern the timing, magnitude, and cellular context of their production. To better delineate these elements, phase III of the Encyclopedia of DNA Elements (ENCODE) Project has expanded analysis of the cell and tissue repertoires of RNA transcription, chromatin structure and modification, DNA methylation, chromatin looping, and occupancy by transcription factors and RNA-binding proteins. Here we summarize these efforts, which have produced 5,992 new experimental datasets, including systematic determinations across mouse fetal development. All data are available through the ENCODE data portal (https://www.encodeproject.org), including phase II ENCODE1 and Roadmap Epigenomics2 data. We have developed a registry of 926,535 human and 339,815 mouse candidate cis-regulatory elements, covering 7.9 and 3.4% of their respective genomes, by integrating selected datatypes associated with gene regulation, and constructed a web-based server (SCREEN; http://screen.encodeproject.org) to provide flexible, user-defined access to this resource. Collectively, the ENCODE data and registry provide an expansive resource for the scientific community to build a better understanding of the organization and function of the human and mouse genomes.This work was supported by grants from the NIH under U01HG007019, U01HG007033, U01HG007036, U01HG007037, U41HG006992, U41HG006993, U41HG006994, U41HG006995, U41HG006996, U41HG006997, U41HG006998, U41HG006999, U41HG007000, U41HG007001, U41HG007002, U41HG007003, U54HG006991, U54HG006997, U54HG006998, U54HG007004, U54HG007005, U54HG007010 and UM1HG009442

Cognitive dysfunction and greater visit-to-visit systolic blood pressure variability

OBJECTIVES: To determine whether variability in blood pressure (BP) is negatively associated with performance on cognitive testing. DESIGN: Multinational, longitudinal, observational cohort study. SETTING: The Alzheimer's Disease Neuroimaging Initiative study. PARTICIPANTS: Individuals with a screening diagnosis of mild cognitive impairment or normal cognition (N=626). MEASUREMENTS: Mean, variance, and maximum BP were calculated based on measures collected from screening to 36 months. Analysis of covariance models were used to determine the association between BP measures and cognitive scores at 36 months after adjusting for covariates. RESULTS: Greater variability in systolic (P.18) BP was associated with worse global (Modified Alzheimer's Disease Assessment Scale Cognitive Component and Clinical Dementia Rating sum of boxes) and executive (Trail-Making Test Part B, Animal Fluency, and Vegetable Fluency) function and episodic memory (Rey Auditory Verbal Learning Test Total Score). CONCLUSION: There is a clinically significant association between greater systolic BP variability and greater cognitive dysfunction. These results should be verified in other well-characterized cohorts, and the neuroanatomical pathophysiology underlying the observed greater cognitive impairment should be further explored

Basic oral care for hematology–oncology patients and hematopoietic stem cell transplantation recipients:a position paper from the joint task force of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) and the European Society for Blood and Marrow Transplantation (EBMT)

Hematology-oncology patients undergoing chemotherapy and hematopoietic stem cell transplantation (HSCT) recipients are at risk for oral complications which may cause significant morbidity and a potential risk of mortality. This emphasizes the importance of basic oral care prior to, during and following chemotherapy/HSCT. While scientific evidence is available to support some of the clinical practices used to manage the oral complications, expert opinion is needed to shape the current optimal protocols. This position paper was developed by members of the Oral Care Study Group, Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) and the European Society for Blood and Marrow Transplantation (EBMT) in attempt to provide guidance to the health care providers managing these patient populations. The protocol on basic oral care outlined in this position paper is presented based on the following principles: prevention of infections, pain control, maintaining oral function, the interplay with managing oral complications of cancer treatment and improving quality of life. Using these fundamental elements, we developed a protocol to assist the health care provider and present a practical approach for basic oral care. Research is warranted to provide robust scientific evidence and to enhance this clinical protocol
