The Effect Of The Lee Silverman Voice Treatment (Lsvt) Big Method Based On Occupation On Older Adult Functional Mobility Balance, Muhammad Luthfi, Kharisma Nur Idalasari

Jurnal Fisioterapi Terapan Indonesia

Balance impairment is one of the major problems commonly experienced by older adults as a result of degenerative processes, leading to an increased risk of falls. Falls may cause fear of recurrent falling, reduced physical activity, loss of physical capability, and may eventually result in disability and psychological consequences such as depression. Structured, occupation-based physical activity has been shown to provide various benefits for older adults, including improving physical function, slowing functional decline associated with degenerative processes, reducing fall risk, and enhancing postural control. This study aimed to analyze the effect of the occupation-based Lee Silverman Voice Treatment (LSVT) BIG …

Understanding disease progression and sophisticated tumor ecosystems is imperative for investigating tumorigenesis mechanisms and developing novel prevention strategies. Here, we dissected heterogeneous microenvironments during malignant transitions by leveraging data from 1396 samples spanning 13 major tissues. Within transitional stem-like subpopulations highly enriched in precancers and cancers, we identified 30 recurring cellular states strongly linked to malignancy, including hypoxia and epithelial senescence, revealing a high degree of plasticity in epithelial stem cells. By characterizing dynamics in stem-cell crosstalk with the microenvironment along the pseudotime axis, we found differential roles of ANXA1 at different stages of tumor development. In precancerous stages, reduced …

The Effectiveness Of Ras Treatment In Improving Gait Patterns In Patients With Parkinson’S Disease: A Literature Review, Vivian Huang, Andrea Hunt, Alicia Chopyk

Rowan-Virtua Research Day

Parkinson’s Disease (PD) is a neurodegenerative disorder involving the loss of dopaminergic neurons leading to symptoms such as tremor and gait disturbance. This results in the classic shuffling gait: stooped posture, variation in stride length, variation in cadence, reduced gait velocity, inability to maintain a steady rhythm, and an increased fear of falling. This study’s objective is to review the current literature on the use of rhythmic auditory stimulation (RAS)Ⓡ as a treatment option for PD. Previous research has looked at RASⓇ as a potential non-pharmacologic treatment because researchers hypothesize that listening to music produces an external rhythm that the …

Center on Aging Staff Publications

Background: The epoxyeicosatrienoic acids (EETs) are derivatives of the arachidonic acid metabolism with anti-inflammatory activities. However, their efficacy is limited due to the rapid hydrolysis by soluble epoxide hydrolase (sEH). Inhibition of sEH has been shown to stabilize the EETs and reduce neuroinflammation in Aβ mouse models of Alzheimer's disease (AD). However, the role of the sEH-EET signaling pathway in other CNS cell types and neurodegenerative conditions are less understood.

Methods: Here we investigated the mechanisms and functional role of the sEH-EET axis in tauopathy by treating PS19 mice with a small molecule sEH inhibitor TPPU and by crossing the …

Many coronavirus disease 2019 (COVID-19) positive individuals exhibit abnormal electroencephalographic (EEG) activity reflecting “brain fog” and mild cognitive impairments even months after the acute phase of infection. Resting-state EEG abnormalities include EEG slowing (reduced alpha rhythm; increased slow waves) and epileptiform activity. An expert panel conducted a systematic review to present compelling evidence that cognitive deficits due to COVID-19 and to Alzheimer’s disease and related dementia (ADRD) are driven by overlapping pathologies and neurophysiological abnormalities. EEG abnormalities seen in COVID-19 patients resemble those observed in early stages of neurodegenerative diseases, particularly ADRD. It is proposed that similar EEG abnormalities in …

Journal of Geriatric Emergency Medicine

The introduction of novel amyloid-targeting therapies for Alzheimer’s disease presents challenges for emergency clinicians. Patients on these therapies may present with amyloid related imaging abnormalities (ARIA) that are only detectable on magnetic resonance imaging and have significant implications for emergency department (ED) pathways, particularly for patients with stroke-like symptoms and those requiring anticoagulants. In this article, we highlight key considerations for the practicing clinician and ED administrators, including the identification of ARIA, protocols for imaging and treatment considerations, and strategies for interdisciplinary collaboration to ensure optimal care for this unique patient population.

Factors Associated With Increased Health Care Utilization For Patients With Dementia With Lewy Bodies: A Narrative Review, Kathryn A. Wyman-Chick, Matthew J. Barrett, Michael J. Miller, Jennifer L. Kuntz, Ella A. Chrenka, Rebecca C. Rossom

Journal of Patient-Centered Research and Reviews

Numerous studies have demonstrated that dementia is associated with increased utilization of health care services, which in turn results in increased costs of care. Dementia with Lewy bodies (DLB) is associated with greater costs of care relative to other forms of dementia due to higher rates of hospitalization and nursing home placement directly related to neuropsychiatric symptoms, parkinsonism, increased susceptibility to delirium, and elevated rates of caregiver burden. There is a critical need for researchers to identify potentially modifiable factors contributing to increased costs of care and poor clinical outcomes for patients with DLB, which may include comorbidities, polypharmacy/contraindicated medications, …
