The impact of mental health disorders on outcomes following total ankle arthroplasty: A systematic review.

Background: The purpose of this systematic review was to evaluate the impact of mental health disorders (MHDs) on the clinical and functional outcomes following total ankle arthroplasty (TAA) for the treatment of end-stage ankle arthritis.

Methods: A systematic review of the EMBASE, MEDLINE, and Cochrane Library databases was conducted in April 2024 following PRISMA guidelines. Data collected included patient demographics, clinical outcomes, complications, and failures.

Activating waitlists: Identifying barriers and facilitators to pain self-management while waiting.

Objectives: Waitlists for pain management services are often extensive, risking psychological and physical decline and patient non-engagement in treatment once accessed. Currently, for outpatient pain management, no standardised waiting list interventions exist, resulting in passive waiting. To arrest prospective wait-related decline(s), this study aimed to identify the barriers and facilitators to pain self-management while waiting, forming the foundation for a waitlist intervention development.

Memory control deficits in the sleep-deprived human brain.

Sleep disturbances are associated with intrusive memories, but the neurocognitive mechanisms underpinning this relationship are poorly understood. Here, we show that sleep deprivation disrupts prefrontal inhibition of memory retrieval, and that the overnight restoration of this inhibitory mechanism is associated with time spent in rapid eye movement (REM) sleep. The functional impairments arising from sleep deprivation are linked to a behavioral deficit in the ability to downregulate unwanted memories, and coincide with a deterioration of deliberate patterns of self-generated thought.

Diversity and evolution of tyrosinase enzymes involved in the adhesive systems of mussels and tubeworms.

Mussels and tubeworms have evolved similar adhesive systems to cope with the hydrodynamics of intertidal environments. Both secrete adhesive proteins rich in DOPA, a post-translationally modified amino acid playing essential roles in their permanent adhesion. DOPA is produced by the hydroxylation of tyrosine residues by tyrosinase enzymes, which can also oxidize it further into dopaquinone.
