Maintaining balance while simultaneously performing other tasks is common during everyday activities. However, this dual-tasking (DT) divides attention and increases cognitive demand, which can be detrimental to stability in older adults. It is unknown if the focus of attention influences how a dual-task affects balance and whether this is detectable in middle-aged adults.

Post-growth: the science of wellbeing within planetary boundaries.

Lancet Planet Health

January 2025

Department of Environmental Sciences and Policy, Central European University, Vienna, Austria.

There are increasing concerns that continued economic growth in high-income countries might not be environmentally sustainable, socially beneficial, or economically achievable. In this Review, we explore the rapidly advancing field of post-growth research, which has evolved in response to these concerns. The central idea of post-growth is to replace the goal of increasing GDP with the goal of improving human wellbeing within planetary boundaries.

People with type 2 diabetes (T2D) are at a higher risk for myocardial infarction (MI) than age-matched healthy individuals. Here, we studied cell-based cardiac regeneration post MI in T2D rats modeling the co-morbid conditions in patients with MI. We recapitulated the T2D hallmarks and clinical aspects of diabetic cardiomyopathy using high-fat diet and streptozotocin in athymic rats, which were then subjected to MI and intramyocardial implantation of human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) with or without rat adipose-derived microvessels (MVs).

Experimental evidence that exerting effort increases meaning.

Cognition

January 2025

Department of Psychology, University of Toronto,; Rotman School of Management, University of Toronto.

Efficiency demands that we work smarter and not harder, but is this better for our wellbeing? Here, we ask if exerting effort on a task can increase feelings of meaning and purpose. In six studies (N = 2883), we manipulated how much effort participants exerted on a task and then assessed how meaningful they found those tasks. In Studies 1 and 2, we presented hypothetical scenarios whereby participants imagined themselves (or others) exerting more or less effort on a writing task, and then asked participants how much meaning they believed they (or others) would derive.

External delay and dispersion correction of automatically sampled arterial blood with dual flow rates.

Biomed Phys Eng Express

January 2025

Brain Health Imaging Centre, Centre for Addiction and Mental Health, B68-250 College St, Toronto, Ontario, M5T 1R8, CANADA.

Objective: Arterial sampling for PET imaging often involves continuously measuring the radiotracer activity concentration in blood using an automatic blood sampling system (ABSS). We proposed and validated an external delay and dispersion correction procedure needed when a change in flow rate occurs during data acquisition. We also measured the external dispersion constant of [11C]CURB, [18F]FDG, [18F]FEPPA, and [18F]SynVesT-1.

Impact of under-assisted ventilation on diaphragm function and structure in a porcine model.

Anesthesiology

January 2025

Department of Anesthesiology and Critical Care Medicine B (DAR B), Saint-Eloi Hospital, University Teaching Hospital of Montpellier, 80 avenue Augustin Fliche, 34295 Montpellier, France.

Background: Long-term controlled mechanical ventilation (CMV) in intensive care unit (ICU) induces ventilatory-induced-diaphragm-dysfunction (VIDD). The transition from CMV to assisted mechanical ventilation is a challenge that requires clinicians to balance over-assistance and under-assistance. While the effects of over-assistance on the diaphragm are well known, we aimed to assess the impact of under-assistance on diaphragm function and structure in piglet model with pre-existing VIDD (after long-term CMV) or without VIDD (short-term CMV).

Management of Insomnia in the General Hospital.

Prim Care Companion CNS Disord

January 2025

Department of Psychiatry, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

Successful resolution of approach-avoidance conflict (AAC) is fundamentally important for survival, and its dysregulation is a hallmark of many neuropsychiatric disorders, and yet the underlying neural circuit mechanisms are not well elucidated. Converging human and animal research has implicated the anterior/ventral hippocampus (vHPC) as a key node in arbitrating AAC in a region-specific manner. In this study, we sought to target the vHPC CA1 projection pathway to the nucleus accumbens (NAc) to delineate its contribution to AAC decision-making, particularly in the arbitration of learned reward and punishment signals, as well as innate signals.

The TRIM-NHL RNA-binding protein MEI-P26 modulates the size of Drosophila Type I neuroblast lineages.

Genetics

January 2025

Department of Molecular Genetics, University of Toronto, 661 University Avenue, Toronto, Ontario, Canada M5G 1M1.

The Drosophila TRIM-NHL RNA-binding protein (RBP), MEI-P26, has previously been shown to suppress tumor formation in the germline. Here we show that, in the Drosophila larval central brain, cell-type specific expression of MEI-P26 plays a vital role in regulating neural development. MEI-P26 and another TRIM-NHL RBP, Brain tumor (BRAT), have distinct expression patterns in Type I neuroblast (NB) lineages: While both proteins are expressed in NBs, BRAT is expressed in ganglion mother cells (GMCs) but not neurons whereas MEI-P26 is expressed in neurons but not GMCs.
