This paper presents a measurement system intended to monitor the usage of walker assistive devices. The goal is to guide the user in the correct use of the device in order to prevent risky situations and maximize comfort. Two risk indicators are defined: one related to force unbalance and the other related to motor incoordination. Force unbalance is measured by load cells attached to the walker legs, while motor incoordination is estimated by synchronizing force measurements with distance data provided by an optical sensor. The measurement system is equipped with a Bluetooth link that enables local supervision on a computer or tablet. Calibration and experimental results are included in the paper.

Default Bulk Ordering and Text Messaging to Enhance Outreach for Lipid Screening: A Randomized Clinical Trial.
JAMA Cardiol

Importance: A comprehensive lipid panel is recommended by guidelines to evaluate atherosclerotic cardiovascular disease risk, but uptake is low.
Objective: To evaluate whether direct outreach including bulk orders with and without text messaging increases lipid screening rates.
Design, Setting, And Participants: Pragmatic randomized clinical trial conducted from June 6, 2023, to September 6, 2023, at 2 primary care practices at an academic health system among patients aged 20 to 75 years with at least 1 primary care visit in the past 3 years who were overdue for lipid screening.

Trade in wood and forest products spans the global supply chain. Illegal logging and associated trade in forest products present a persistent threat to vulnerable ecosystems and communities. Illegal timber trade has been linked to violations of tax and conservation laws, as well as broader transnational crimes.

McCaig Institute for Bone and Joint Health, Cumming School of Medicine, University of Calgary, Calgary AB, Canada.
Immune checkpoint inhibitors (ICI) are widely used in cancer treatment, yet their impact on bone health remains unclear. This study aimed to perform a retrospective cohort study utilizing routine computed tomography (CT) scans from patients with melanoma to perform opportunistic quantitative CT (QCT) analysis to investigate the effects of ICI treatment on skeletal health, including volumetric bone mineral density (vBMD) measurements and osteoarthritis (OA) parameters. A previously established machine-learning assisted opportunistic QCT pipeline was used to estimate lumbar spine vBMD from baseline and 12-month follow-up CT scans in patients with melanoma treated with ICI therapy and those not treated with ICI therapy.

Purpose: Bangladesh has experienced a rapid epidemiological transition from communicable to non-communicable diseases (NCDs) in recent decades. There is, however, limited evidence about multidimensional determinants of NCDs in this population. The BangladEsh Longitudinal Investigation of Emerging Vascular and nonvascular Events (BELIEVE) study is a household-based prospective cohort study established to investigate biological, behavioural, environmental and broader determinants of NCDs.
