Purpose/Background

Delirium is an acute disorder yielding cognitive deficits, such as disruption in attention and awareness. It impacts approximately 50% of individuals over the age of 65 who are admitted to the hospital and is prevalent with patients in the intensive care unit (ICU). ICU delirium is associated with adverse outcomes, including higher morbidity, prolonged hospital stays, and chronic neurocognitive deficits. Research demonstrates that implementation of a non-pharmacological sleep bundle can reduce the overall occurrence of delirium. The purpose of this scoping review is to examine the efficacy of a non-pharmacological sleep bundle on the incidence of ICU delirium in …

Department of Occupational Therapy Faculty Papers

Background

Despite over 200 evidence-based dementia caregiver programs, we know little about the best approaches for optimally scaling these programs in daily service contexts, nor do we fully understand the most effective approaches of ensuring successful implementation. As a result, a small fraction of the many individuals living with dementia and their caregivers within in the US have access to evidence-based programs. A leading barrier to implementation of evidence-based dementia caregiver support programs into long-term care settings is the lack of streamlined, scalable, user-friendly, and tested training modalities.

Objective

To describe the protocol for a study evaluating the implementation of …

Department of Occupational Therapy Faculty Papers

Complexity of care is the inevitable consequence of an aging population and is particularly true in instances where patients are managing chronic conditions such as heart failure with reduced ejection fraction (HFrEF). HFrEF itself is complex, with an undulating course of illness, increased risk of sudden cardiac death, and myriad accompanying treatment considerations. Generalist management of HFrEF among older patients is further complicated by competing comorbidities, potential for financial toxicity, potential for mental health symptoms, and risk of care with does not align with goals and preferences. The 5Ms (multicomplexity, mind, mobility, medications, and matters most) is a holistic conceptualization …

Cancer Of Unknown Primary With Squamous Cell Carcinoma Phenotype Presenting As Isolated Axillary Mass, Nicole Liang, Mohamed Ashal, Lynne J. Goebel

Internal Medicine

Cancer of unknown primary (CUP) is a rare metastatic malignancy where no primary tumor can be found. We report the case of a 71-year-old female with a strong family history of breast cancer presenting with isolated axillary lymphadenopathy after a tick bite. A biopsy of the axillary mass revealed poorly differentiated squamous cell carcinoma and after extensive evaluation, she was diagnosed with metastatic squamous cell carcinoma with unknown primary tumor. We present this case because of the role of confounding history complicating her initial diagnosis and bringing awareness to a rare disease.

Blood-based biomarkers continue to be explored for disease detection, monitoring of progression, and therapeutic outcomes as the diagnostic determination of Alzheimer’s Disease in Down Syndrome (DS-AD) remains challenging in clinical settings. This perspective highlights the current status of this effort. Overall, amyloid (A), tau (T), and neurodegeneration (AT[N]) blood-based biomarkers have been shown to increase with disease pathology for individuals with DS. Phosphorylated tau biomarkers (p-tau217, p-tau181) have been consistently shown to track disease progression for DS-AD and are likely good candidates for use in clinical settings. Biomarkers of inflammation (glial fibrillary acidic protein) also show promise; however, additional work …
