Objectives: This study aimed to examine the associations of arthritis with functional disability and depressive symptoms among general US adults. Additionally, it explored the relationship between radiographic knee osteoarthritis (assessed by X-ray examination) and functional disability. Above findings seek to highlight the need for comprehensive physical and mental health management in individuals with arthritis.
Methods: We designed a cross-sectional study utilizing multivariable logistic regression models to examine the associations. Odds ratios (OR) and corresponding 95% confidence intervals (CI) were documented in a crude model and three adjusted models. Participants were from the National Health and Nutrition Examination Survey (NHANES) 1988-1994 and 1999-2018. Arthritis was self-reported or graded by the Kellgren-Lawrence score after an objective X-ray examination. Functional disability included disability in activities of daily living (ADL disability), instrumental activities of daily living (IADL disability), and mobility disability. Depressive symptom was assessed using the Patient Health Questionnaire (PHQ).
Results: We included 22,566 older adults (≥60 years; 10,961 had self-reported arthritis) for functional disability analysis (2377 older adults with data on X-ray examination; 1012 had radiographic knee osteoarthritis) and 32,056 adults (≥20 years; 9175 had self-reported arthritis) for depressive symptom analysis. After controlling for all covariates, self-reported arthritis was associated with ADL disability (odds ratios [OR]: 2.677; 95% confidence interval [CI]: 2.499-2.868), IADL disability (OR: 2.064; 95% CI: 1.940-2.196), and mobility disability (OR: 2.954; 95% CI: 2.778-3.142), and depressive symptom (OR: 2.177; 95% CI: 1.979-2.395). In participants with data on X-ray examination, radiographic knee osteoarthritis was only associated with mobility disability (OR: 1.437; 95% CI: 1.183-1.744).
Conclusions: Self-reported arthritis was associated with ADL disability, IADL disability and mobility disability, and depressive symptoms. Among participants with X-ray data, radiographic knee osteoarthritis was only associated with mobility disability in general US adults. Appropriate managements of both physical and mental health are needed for individuals with arthritis.

Background: Parkinson's disease is an hypokinetic disorder characterized by selective loss of dopaminergic in substantia nigra pars compacta (SNPc) region of mid-brain. Dopaminergic degeneration of neurons is considered to be due to oxidative stress, neuroinflammation, neurons mitochondrial dysfunction and glutamate excitotoxicity etc. Filgrastim has been reported to produce anti-oxidant, anti-inflammatory and neuromodulatory actions in previous studies.

Background: To bolster clinical trial infrastructure, there is a need to develop novel, valid, and reliable patient-reported outcome (PRO) measures capable of tracking clinically-relevant changes in Alzheimer's disease (AD), Mild Cognitive Impairment (MCI) and dementia over time. This research describes the development and validation of the Alzheimer's Disease-Health Index (AD-HI) as a tool to measure how patients feel and function in response to therapeutic intervention.
Method: We previously conducted semi-structured qualitative interviews and a national cross-sectional study with individuals with AD, MCI and dementia to ascertain the most prevalent and impactful symptoms identified by the participants.

Background: Evidence in adults without Down syndrome (DS) suggests that exercise during mid-life improves cognitive function and decreases risk of later life dementia. Studies supporting this relationship in adults with DS are limited. The purpose of this study was to examine changes in cognitive function after a 12-mo exercise intervention in adults with DS without dementia.

Background: People with dementia of all ages have a human right to equal access to quality health care. Despite evidence regarding its effectiveness, many people living with dementia lack access to evidence-based rehabilitation for promoting function and quality of life. The aims of this study were to 1) explore barriers to access to dementia rehabilitation; and 2) identify solutions which improve access to rehabilitation.

Background: Alzheimer's disease (AD) affects over 55 million people worldwide and is characterized by abnormal deposition of amyloid-β and tau in the brain causing neuronal damage and disrupting transmission within brain circuits. Episodic memory loss, executive deficits, and depression are common symptoms arising from altered function in spatially distinct brain circuits that greatly contribute to disability. Transcranial electrical stimulation (tES) can target these circuits and has shown promise to relieve specific symptoms.
