RESUMEN
How and where patients with advanced cancer facing limited survival spend their time is critical. Healthcare contact days (days with healthcare contact outside the home) offer a patient-centered and practical measure of how much of a person's life is consumed by healthcare. We retrospectively analyzed contact days among decedent veterans with stage IV gastrointestinal cancer at the Minneapolis Veterans Affairs Healthcare System from 2010 to 2021. Among 468 decedents, the median overall survival was 4 months. Patients spent 1 in 3 days with healthcare contact. Over the course of illness, the percentage of contact days followed a "U-shaped" pattern, with an initial post-diagnosis peak, a lower middle trough, and an eventual rise as patients neared the end-of-life. Contact days varied by clinical factors and by sociodemographics. These data have important implications for improving care delivery, such as through care coordination and communicating expected burdens to and supporting patients and care partners.

BACKGROUND: Delay discounting refers to the devaluation of a reward given increasing delays to delivery. Similarly, effort discounting refers to the devaluation of a reward given increasing effort required to obtain it. Individuals with substance use disorder show higher rates of delay discounting, exacerbating short-term positive reinforcement at the expense of long-term consequences. This study explores how effort discounting compares to delay discounting behavior among alcohol users as well as how these preferences change between monetary and alcohol rewards. METHODS: A total of 100 participants completed an online survey through Amazon Mechanical Turk. Participant alcohol use was evaluated using DSM-5 and the Alcohol Use Disorders Identification Test criteria. All participants completed 4 randomized discounting tasks involving delay or effort discounting, in which the reward was money or alcohol. A follow-up experiment (n = 423) added the alcohol purchase task to assess alcohol valuation. RESULTS: Individuals with greater alcohol use disorder (AUD) severity discounted future money and alcohol significantly more than those with less AUD. However, individuals meeting more DSM-5 criteria were only willing to perform more effort for alcohol. The follow-up experiment replicated these findings and demonstrated that individuals with greater AUD also showed an increased valuation of alcohol and alcohol value-mediated effort discounting. CONCLUSIONS: These results suggest that individuals with greater AUD were less willing to wait for money or alcohol. While all participants were willing to work for money regardless of AUD severity, individuals with greater AUD showed increased valuation of alcohol drinks and were willing to exert more effort to obtain alcohol. Together, these results paint a picture of individuals with increased AUD as both more impulsive and willing to work to obtain alcohol, contributing to our understanding of decision making among individuals who abuse substances.

DTNBP1 (dystrobrevin binding protein 1) is a leading candidate susceptibility gene in schizophrenia and is associated with working memory capacity in normal subjects. In schizophrenia, the encoded protein dystrobrevin-binding protein 1 (dysbindin-1) is often reduced in excitatory cortical limbic synapses. We found that reduced dysbindin-1 in mice yielded deficits in auditory-evoked response adaptation, prepulse inhibition of startle, and evoked γ-activity, similar to patterns in schizophrenia. In contrast to the role of dysbindin-1 in glutamatergic transmission, γ-band abnormalities in schizophrenia are most often attributed to disrupted inhibition and reductions in parvalbumin-positive interneuron (PV cell) activity. To determine the mechanism underlying electrophysiological deficits related to reduced dysbindin-1 and the potential role of PV cells, we examined PV cell immunoreactivity and measured changes in net circuit activity using voltage-sensitive dye imaging. The dominant circuit impact of reduced dysbindin-1 was impaired inhibition, and PV cell immunoreactivity was reduced. Thus, this model provides a link between a validated candidate gene and an auditory endophenotypes. Furthermore, these data implicate reduced fast-phasic inhibition as a common underlying mechanism of schizophrenia-associated intermediate phenotypes.

BACKGROUND: After-hour calls can be resource intensive and remain a significant challenge to medical practices, though they have historically been poorly or non-reimbursable services. This study reviews after-hour calls from hematology/oncology patients at a cancer center to characterize after-hour care needs, identify care gaps, and look for opportunities to improve outpatient healthcare delivery. METHODS: This descriptive, retrospective Institutional Review Board-approved study analyzed patient calls between June 2015 to February 2021 in an academic hematology/oncology practice. Data from 500 calls were reviewed and cataloged into a database including patient demographics, clinical history, and information surrounding the call (e.g., primary reason for the call, outcome of the call). Calls were also categorized as being urgent or not from a patient or provider's perspective. RESULTS: Among 500 calls, representing 398 unique patients, the average patient was 62 years old and 52% of calls were from females. Most calls were made to report symptoms (65%), followed by calls to follow-up on labs, tests, or imaging (13%), and clarifying treatment plans (10%). Oncology patients represented 67% of calls and hematology (malignant and benign) patients represented 33%. More specifically, patients with gastrointestinal cancer (25%), hematologic malignancies (24%), and thoracic cancer (13%) represented the diagnoses with the highest call volume. CONCLUSIONS: This study explores the complexity and variety of after-hour cancer patient calls. By systematically exploring patient calls, this data can provide insight into patients' needs outside of regular clinic times and help practices develop strategies to anticipate these needs, reduce after-hour call burden, and improve overall quality of care.
