Hypercalcaemia of malignancy: a case of vitamin-D-mediated hypercalcaemia in lymphoma.

Hypercalcaemia of malignancy (HCM) is a paraneoplastic syndrome that often portends a poor prognosis. We present an extremely rare (<1%) case of HCM due to extrarenal calcitriol (1,25-(OH)D) production in a patient with splenic marginal zone lymphoma. A man in his 80s presented with a 3-week history of fatigue, unsteadiness and abdominal pain, and new findings of anaemia, kidney injury and hypercalcaemia.

Workload transition rate matters: Evidence from growth curve modeling.

This research examined three specific gaps in the workload transition literature: (1) the impact of workload transition rate, (2) the applicability of current theoretical explanations, and (3) the variability of performance overall and over time. Sixty Naval flight students multitasked in an unmanned aerial vehicle control testbed and workload transitioned at three rates: slow, medium, or fast. Response time and accuracy were analyzed via growth curve modeling.

Scan-based eye tracking measures are predictive of workload transition performance.

Given there is no unifying theory or design guidance for workload transitions, this work investigated how visual attention allocation patterns could inform both topics, by understanding if scan-based eye tracking metrics could predict workload transition performance trends in a context-relevant domain. The eye movements of sixty Naval flight students were tracked as workload transitioned at a slow, medium, and fast pace in an unmanned aerial vehicle testbed. Four scan-based metrics were significant predictors across the different growth curve models of response time and accuracy.

Near-Perfect Automation: Investigating Performance, Trust, and Visual Attention Allocation.

Objective: Assess performance, trust, and visual attention during the monitoring of a near-perfect automated system.

Background: Research rarely attempts to assess performance, trust, and visual attention in near-perfect automated systems even though they will be relied on in high-stakes environments.

Methods: Seventy-three participants completed a 40-min supervisory control task where they monitored three search feeds.

Transitions Between Low and High Levels of Mental Workload can Improve Multitasking Performance.

Complex and dynamic environments including military operations, healthcare, aviation, and driving require operators to transition seamlessly between levels of mental workload. However, little is known about how the rate of an increase in workload impacts multitasking performance, especially in the context of real-world tasks. We evaluated both gradual and sudden workload increases in the dynamic multitasking environment of an Unmanned Aerial Vehicle (UAV) command and control testbed and compared them to constant workload.

A Retrospective Analysis of Pain Burden in Hospitalized Young Adult Cancer Patients Compared with Their Older Adult Counterpart.

Context: Research shows an increased symptom burden in young adult (YA) cancer patients compared with their older adult counterpart.

Objectives: The purpose of this study was to identify differences in clinical characteristics and related outcomes between YA and older adult cancer patients admitted for cancer-related pain.

Materials And Methods: We retrospectively identified 190 hospitalized patients in a single academic center with admissions for cancer-related pain.
