Abstract
INTRODUCTION Adverse drug reactions (ADRs) are common among people with dementia; however, little is known about the magnitude and predictors associated with ADR-related hospitalisation among these individuals. This study aimed to determine the magnitude, types, drugs implicated and predictors of ADRs associated with hospitalisation among people with dementia. METHODS This retrospective case-control study analysed medical records of individuals aged ≥ 65 years with dementia admitted to major public hospitals in Tasmania, Australia, from July 2010 to July 2021. Adverse drug reactions and implicated drugs were identified using administrative data and cross-checked with hospital medical records, with consensus reached among the research team. RESULTS Of the 7928 people admitted to hospital at least once within the study period, 1876 (23.7%) experienced at least one ADR-related hospitalisation. Of these, 300 case patients with 311 ADRs and 300 control patients were randomly selected. The most common types of ADRs were renal (acute kidney injury; AKI) (36.0%), followed by neuropsychiatric (17.6%), cardiovascular (16.0%) and haematological (13.1%). Diuretics, renin-angiotensin system (RAS) inhibitors and anti-thrombotics constituted the main implicated drug classes. The ADR-related hospitalisation was associated with: chronic kidney disease (CKD) (OR 8.00, 95% CI 2.63-24.28, p < 0.001), Australian-born (OR 1.62, 95% CI 1.08-2.43, p = 0.019), hypertension (OR 1.48, 95% CI 1.01-2.17, p = 0.044) and the number of medicines (OR 1.06, 95% CI 1.00-1.12, p = 0.022). Potentially inappropriate medication use and anticholinergic burden did not predict ADR-related hospitalisation. CONCLUSIONS These predictors could help identify the individuals at the highest risk and enable targeted interventions to be designed.

Abstract
Nurses, regardless of their area of practice, may have to care for a person in their last days and hours of life. However, many nurses outside of specialist palliative and end of life care settings do not feel adequately prepared for this. Nurses can usually obtain advice from specialists working in local hospices or palliative care centres, but they may still find it challenging to act on that advice if it is not underpinned by their own knowledge base. This article provides a guide to assist non-palliative care nurses in recognising dying and managing common symptoms at the end of life.

Abstract
Natural products are compounds isolated from plants that provide a variety of lead structures for the development of new drugs by the pharmaceutical industry. The interest in these substances increases because of their beneficial effects on human health. Alzheimer's disease (AD) affects occur in about 80% of individuals aged 65 years. AD, the most common cause of dementia in elderly people, is characterized by progressive neurodegenerative alterations, as decrease of cholinergic impulse, increased toxic effects caused by reactive oxygen species and the inflammatory process that the amyloid plaque participates. In silico studies is relevant in the process of drug discovery; through technological advances in the areas of structural characterization of molecules, computational science and molecular biology have contributed to the planning of new drugs used against neurodegenerative diseases. Considering the social impairment caused by an increased incidence of disease and that there is no chemotherapy treatment effective against AD; several compounds are studied. In the researches for effective neuroprotectants as potential treatments for Alzheimer's disease, natural products have been extensively studied in various AD models. This study aims to carry out a literature review with articles that address the in silico studies of natural products aimed at potential drugs against Alzheimer's disease (AD) in the period from 2015 to 2021.

Abstract
PURPOSE People with dementia may have indications for aspirin prescription and clinicians are asked to balance the potential risks against benefits. This review examines the evidence for the risk and benefit of long-term aspirin use in people with dementia aged over 65 years, including randomised controlled trials and observational studies. METHODS We searched three databases for research published between 2007 and 2020. Each eligible article was assessed for risk of bias, and confidence in findings was rated using Grading of Recommendations Assessment, Development and Evaluation (GRADE). RESULTS Four papers met inclusion criteria: one randomised controlled trial, two cohort studies, and one with pooled data. All looked only at dementia of Alzheimer's type, and none addressed myocardial or cerebral infarction as outcomes. Dementia progression was reported by two studies, with conflicting results. The trial found no significant effect of aspirin on mortality (odds ratio aspirin vs. no aspirin 1.07, 95% confidence interval 0.58-1.97) but found more events of severe bleeding with aspirin (OR aspirin vs. no aspirin 6.9, 1.5-31.2). An excess in intracranial haemorrhage in the aspirin group was judged plausible based on two non-randomised studies. CONCLUSIONS The review findings are limited because studies include only people with Alzheimer's-type dementia and lack confirmatory studies, although an increased risk of bleeding events is recognised. Further research that addresses the benefits and risks of aspirin in more representative groups of people with dementia is needed to guide prescribing decisions.

Br J Clin Pharmacol 2020; 87:375-385. [PMID: 32520427 DOI: 10.1111/bcp.14417] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Revised: 05/28/2020] [Accepted: 06/01/2020] [Indexed: 12/18/2022] Open
Abstract
AIMS This systematic review aimed to quantify the prevalence of adverse drug events (ADEs) and adverse drug reactions (ADRs) in older inpatients with dementia. METHODS A systematic search of observational studies was performed in Embase, Medline, PsycINFO, International Pharmaceutical Abstracts, Scopus and Informit. Articles published in English that reported the prevalence of ADEs or ADRs in hospital patients aged 65 years or older with dementia were included. Two authors reviewed titles and abstracts and all eligible full-text articles. Relevant information relating to ADEs, ADRs and dementia was obtained from each article. RESULTS In total, 5 articles were included. One study reported the prevalence of ADEs to be 81.5%, defined using the Naranjo algorithm. Four studies assessed the prevalence of ADRs, ranging from 12.7 to 24.0%, assessed using various methods. One study defined ADRs according to the World Health Organization-Uppsala Monitoring Centre criteria, 2 studies employed the World Health Organization definition and 1 study did not explicitly define ADRs. The most frequently reported drug classes implicated in ADEs and ADRs were psychotropic, antihypertensive and analgesic drugs. CONCLUSION Our findings suggest a high prevalence of ADEs and ADRs in older inpatients with dementia. However, only 1 study documented ADEs and there was variability in approaches to ADR assessment. A greater understanding of ADEs and ADRs, as well as tailored assessment tools, will promote prevention of ADEs and ADRs in people with dementia.

Abstract
BACKGROUND In order to analyze use of health services and identify sources of delays in accessing the right care for patients with Alzheimer's disease and related dementias (AD/ADRD), understanding of care seeking pathways is needed. The objectives of this study were: (i) to explore pathways to hospital care for patients with AD/ADRD and (ii) to describe challenges experienced by the patients and their families while seeking health care. METHODS Using purposive sampling, 30-in-depth, semi-structured interviews were conducted among caregivers of older adults diagnosed with dementia from rural Southwestern, Uganda. Data was analyzed using ATLAS. Ti software. RESULTS There was variability in pathways to care from individual to individual. There was one broader theme captured: points of care choice with four broader categories: hospitals, clinics, places of religious worship and traditional healers' shrines, each with its facilitating factors, outcomes and challenges encountered. Most of the respondents reported use of hospitals at first and second visit to the health care point but places of religious worship became more common from third to sixth health care encounter. Major improvements (58.1%) were observed on hospital use but little or no help with prayers, clinics and traditional healers. The challenges experienced with formal points of care focused on lack and cost of prescribed drugs, weakening effect of the drugs, lack of skills to manage the condition, and lack of improvement in quality of life. These challenges together with knowledge gap about the disease and belief in spiritual healing facilitated the shift from formal to informal health care pathways, more particularly the places of religious worship. CONCLUSIONS Our study findings indicate that caregivers/families of patients with dementia went to different places both formal and informal care settings while seeking health care. However, hospital point of care was more frequent at initial health care visits while places of worship took the lead at subsequent visits. Although no specific pathway reported, most of them begin with hospital (formal) and end with non-formal. We recommend that health systems carry out public awareness on dementia.

Abstract
OBJECTIVES More people with dementia also fall into the category of high vascular risk, for which a statin is usually prescribed. However, these recommendations are based on studies in people without dementia. We aimed to evaluate the evidence for the long-term effectiveness and harm of statin therapy in patients with dementia. DESIGN Systematic review of randomized controlled trials and observational research. SETTING Publications from developed countries indexed in the PubMed, Web of Science, and Cochrane trial database between 2007 and 2019. PARTICIPANTS Trials including people with all types of dementia with a mean age older than 65 years. INTERVENTION Treatment with a statin for 6 months or longer. MEASUREMENTS Major adverse cardiovascular events, dementia progression, and general health at 2 years, or medication adverse events (AEs) at any time. Each article was assessed for bias using the Newcastle-Ottawa or Cochrane Collaboration tools. A narrative synthesis and pooled analyses are reported. RESULTS Five articles met the inclusion criteria. They reported only on dementia of the Alzheimer's type. There was no evidence regarding cardiovascular events or general health. We made a very low confidence finding that statins reduce dementia progression based on three cohort studies of heterogeneous design. We made a very low confidence finding of no significant difference in AEs based on two randomized controlled trials of 18 months: odds ratios of any AE = 1.21 (95% confidence interval [CI] = .83-1.77), serious AE = 1.03 (95% CI = .76-1.87), and death = 1.69 (95% CI = .79-3.62). CONCLUSION Evidence was insufficient to fully evaluate the efficacy of statins in people with dementia. We found that statins may have a small benefit delaying progression in Alzheimer's dementia, although this conflicted with previous findings from shorter randomized trials. For safety, the trial data lacked power to show clinically important differences between the groups. We recommend that clinical data be leveraged for further observational studies to inform prescribing decisions. J Am Geriatr Soc 68:650-658, 2020.

Abstract
This study examined the use of potentially inappropriate medicines that may affect cognition (PIMcog) in people with dementia and its associated factors. Medical records of all outpatients with dementia attending a tertiary hospital in Vietnam between January 1, 2015, and December 31, 2016, were examined. Medicine use was assessed against a list of PIMcog. Variables associated with having a PIMcog were assessed using a multiple logistic regression. Of the 128 patients, 41% used a PIMcog, 39.1% used cholinesterase inhibitors (CEIs) concomitantly with anticholinergics, and 18% used antipsychotics. The number of hospital visits (adjusted odds ratio [OR]: 1.08; 95% confidence interval [CI]: 1.02-1.16) and number of treating specialists (adjusted OR: 0.61; 95% CI: 0.45-0.83) were associated with PIMcog use. This study highlights a high-level use of medicines that can further impair cognition or reduce the effectiveness of CEIs in people with dementia. Efforts to improve quality use of medicines for this population are warranted.

Abstract
OBJECTIVE To describe the prevalence and concordance of anticholinergic exposure according to 9 published scales, to quantify the relative weight of the drug subtypes included in each scale, and to identify clinical variables related to anticholinergic exposure. METHODS Observational and cross-sectional study using 5323 cases of dementia diagnosed in the 7 hospitals of the public health care system of the Health Region of Girona (Spain) between 2007 and 2014 and registered by the Registry of Dementias of Girona (ReDeGi). We used the Pharmacy database that includes all the drugs prescribed by specialist and primary care physicians and dispensed in pharmacies. We calculated the anticholinergic exposure using the scoring rules of each scale. Age, gender, place of residence, dementia subtype, Clinical Dementia Rating score, Mini-Mental Status Examination score, and Blessed Dementia Rating Score at the moment of dementia diagnose were retrieved from the ReDeGi. RESULTS Prevalence of the annual anticholinergic exposure ranged from 36.3% to 69.0% according to the different scales, the concordance among scales was poor to moderate, and the central nervous system drugs accounted the most for anticholinergic exposure. Being in a nursing home, having depressive symptoms, having a non-Alzheimer's dementia subtype, the number of drug treatments, and the severity of dementia were main determinants of anticholinergic exposure. CONCLUSIONS There is a large difference in outcomes among the 9 anticholinergic risk scales. Clinicians and researchers should be aware of these differences when using these instruments in patients with dementia.

Abstract
This article presents a list of potentially delirogenic properties of drugs that are currently of relevance to drug therapy in Europe, which was created through a Delphi process including experts from professions relevant to diagnosis and treatment of delirium. The Diagnostic and Statistical Manual of Mental Disorders 5 (DSM 5) defines delirium as a disturbance in attention, awareness and cognition that develops over a short period of time and fluctuates. Possible causes of delirium are manifold: usually delirium is considered to develop in a multifactorial way, caused by inalterable parameters, such as advanced age and pre-existing cognitive impairment and precipitated by modifiable parameters, such as the use of certain drugs or substance withdrawal. Delirium is a serious condition with a pronounced impact on morbidity, mortality and costs to the healthcare system. Circumstances and drugs that might precipitate or worsen delirium should therefore be avoided whenever possible. A list of drugs that might have a detrimental influence on the emergence and duration of delirium has been created using the terms "delirogenity" and "delirogenic" to describe the potential of a drug or withdrawal to cause or worsen delirium. The results are novel and noteworthy, as their focus is on substances relevant to European pharmacotherapy. Furthermore, they represent a methodical consensus from a group of experts of a wide variety of professions relevant to the prevention, diagnosis and treatment of delirium, such as nursing, pharmacy, pharmacology, surgical and internal medicine, neurology, psychiatry, intensive care and medicine, with working, teaching and scientific experience in several European countries practicing both in primary and secondary care.
