Development and initial validation of the Cognitive Change Scale (CCS).

Background: Cognitive impairment is common in neurologic diseases. Precise measurement of cognitive change over time is necessary for isolating disease-related patterns from normal age-related decline. Existing measures of subjective cognition, however, focus on present status.

Psychotic symptoms are associated with elevated tau PET signal in the amygdala independent of Alzheimer's disease clinical severity and amyloid burden.

Background: Psychosis in Alzheimer's disease (AD) is associated with worse outcomes, yet no established biomarkers exist for early diagnosis and intervention. We compared tau PET burden across older individuals with and without psychotic symptoms.

Methods: [F]AV1451 tau PET binding was compared between 26 Alzheimer's Disease Neuroimaging Initiative (ADNI) subjects with psychotic symptoms (delusions and/or hallucinations) and 26 ADNI subjects without psychotic symptoms, matched for age, sex, race/ethnicity, and clinical severity.

Health-Related Quality of Life and Depression Symptoms in a Cross Section of Patients with Advanced Lung Cancer before and during the COVID-19 Pandemic.

Adults with advanced lung cancer experience reduced health-related quality of life (HRQOL) and psychological symptoms at diagnosis. This study aimed to evaluate whether the COVID-19 pandemic worsened HRQOL among patients recently diagnosed with cancer. We analyzed baseline data from two randomized controlled trials of early palliative care to compare HRQOL and depression symptoms among those enrolled during the pandemic (January 2020 to January 2021) versus prepandemic (March 2018 to January 2019).

A discrete parasubthalamic nucleus subpopulation plays a critical role in appetite suppression.

Food intake behavior is regulated by a network of appetite-inducing and appetite-suppressing neuronal populations throughout the brain. The parasubthalamic nucleus (PSTN), a relatively unexplored population of neurons in the posterior hypothalamus, has been hypothesized to regulate appetite due to its connectivity with other anorexigenic neuronal populations and because these neurons express Fos, a marker of neuronal activation, following a meal. However, the individual cell types that make up the PSTN are not well characterized, nor are their functional roles in food intake behavior.

Study protocol for a randomised trial evaluating the non-inferiority of stepped palliative care versus early integrated palliative care for patients with advanced lung cancer.

Introduction: Integrating palliative care (PC) early in the illness course for patients with serious cancers improves their outcomes and is recommended by national organisations such as the American Society of Clinical Oncology. However, monthly visits with PC clinicians from the time of diagnosis can be challenging to implement due to the lack of specialty-trained PC clinicians and resources. Therefore, we developed a stepped care model to triage PC service based on patients' needs.
