Evaluation of measurement equivalence of the Family Satisfaction with the End-of-Life Care (FAMCARE): Tests of differential item functioning between Hispanic and non-Hispanic White caregivers.

Evaluation of measurement equivalence of the Family Satisfaction with the End-of-Life Care (FAMCARE): Tests of differential item functioning between Hispanic and non-Hispanic White caregivers. Palliat Support Care. 2020 Mar 19;:1-13 Authors: Teresi JA, Ocepek-Welikson K, Ramirez M, Kleinman M, Ornstein K, Siu A, Luchsinger J Abstract OBJECTIVE: Although the psychometric properties of the Family Satisfaction with End-of-Life Care measure have been examined in diverse settings internationally; little evidence exists regarding measurement equivalence in Hispanic caregivers. The aim was to examine the psychometric properties of a short-form of the FAMCARE in Hispanics using latent variable models and place information on differential item functioning (DIF) in an existing family satisfaction item bank. METHOD: The graded form of the item response theory model was used for the analyses of DIF; sensitivity analyses were performed using a latent variable logistic regression approach. Exploratory and confirmatory factor analyses to examine dimensionality were performed within each subgroup studied. The sample included 1,834 respondents: 317 Hispanic and 1,517 non-Hispanic White caregivers of patients with Alzheimer's disease and cancer, respectively. RESULTS: There was strong support for essential unidimensionality for both Hispanic and non-Hispanic White subgroups. Modest DIF of low magnitude and impact was observed; flagged items related to informatio...

This study aimed to characterize the role of BDNF in age-related microglial activation. Initially, we found that degrees of microglial activation were especially evident in the substantia nigra (SN) across different brain regions of aged mice. The levels of BDNF and TrkB in microglia decreased with age and negatively correlated with their activation statuses in mice during aging. Interestingly, aging-related microglial activation could be reversed by chronic, subcutaneous perfusion of BDNF. Peripheral lipopolysaccharide (LPS) injection-induced microglial activation could be reduced by local supplement of BDNF, while shTrkB...

This article provides an overview of the evidence on the risks and benefits of using medical cannabis for the indications of chronic pain, cancer-related pain, cancer cachexia, dementia, and Alzheimer's disease. Currently, there is insufficient evidence to determine the effectiveness and safety of cannabinoids for most reviewed indications, with the exception of chronic pain. Future research is required before palliative care clinicians can make evidence-based decisions on the integration of medical cannabis as adjunct therapies. PMID: 32312410 [PubMed - in process]

In this study, the Morris water maze (MWM) experiment was adopted to evaluate the cognitive-enhancing effects of the studied plant extracts. The malondialdehyde (MDA) profiles in the brains of experimental mice were determined using the thiobarbituric acid reactive substances (TBARS) test. Moreover, qualitative phytochemical profiling of the studied plant extracts was performed using standard procedures. The results showed remarkable cognitive-enhancing activities which were reflected in significantly shorter transfer latencies, navigation distances, longer time spent in platform quadrant, and lower MDA levels compared wit...

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons. Epige...

Abstract While end-of-life (EOL) care has been a relatively common option for patients with terminal cancer, the utilization of EOL care in Alzheimer disease and other dementias has become available more recently. By the time end-stage dementia is present, the clinicians and caregivers become faced with multiple clinical issues-their inability to provide subjective complaints of pain and discomfort, behavioral symptoms, delirium, food refusal, and so on. In addition to providing quality EOL care to the patients, clinicians need to work with their families in an open and empathic manner, assuring that their loved o...

Many people have heard of hospice care but they mistakenly think that it’s just a way to help cancer patients be more comfortable at the end of their lives. Fewer people have heard of palliative care, and they may have no idea what it is. The truth is that hospice and palliative care are related but used for different reasons at different times, and everyone should be well-versed in what they offer. Here, we’ll clarify some points of confusion.

, Eroğlu H Abstract Alzheimer's Disease (AD) is one of the most challenging diseases faced by humankind. AD is still not classified as curable because of the complex structure of pathologies underlying it. As the mean life expectancy of the world population constantly increases, the prevalence of AD and treatment costs for AD also grow rapidly. Current state of the art for AD treatment mainly consists of palliative therapy aimed at providing symptomatic relief and improving the standard of living in patients with AD. However, different research groups are working on more effective and safe drug delivery options a...
