Methicillin-resistant (MRSA) is the leading cause of wound infections, often progressing into serious invasive bloodstream infections. MRSA disproportionately affects Indigenous peoples in Canada with higher rates of skin and wound infections, an example of persistent gaps in health outcomes between Indigenous and non-Indigenous peoples precipitated by the legacy of colonialism. Conversely, Indigenous peoples have long used natural remedies for infections and other diseases; however, their knowledge was rarely considered for modern medicine.

Many oil and gas developments will soon be decommissioned and, knowledge on the accumulation of mercury (Hg), throughout offshore infrastructure is limited. Any release of Hg could have a detrimental impact on marine ecosystems. To bridge this knowledge gap, a fractionation approach was taken on steel samples exposed to Hg and HS, separating Hg compounds removed from the surface into polar, non-polar and insoluble fractions.

Background: Amygdala function underlying emotion processing has been shown to vary with an individuals' biological sex. Expanding upon functional magnetic resonance imaging (fMRI) findings reported previously where a low level of response was the focus, we examined alcohol and sex effects on functional connectivity between the amygdala and other brain regions. The central hypothesis predicted that sex would influence alcohol's effects on frontal-limbic functional circuits underlying the processing of negative and positive facial emotions.

Unlabelled: WHAT IS KNOWN ON THE SUBJECT?: Safewards was developed for acute mental health units, and while could be effective in forensic mental health services, there are some gaps in the model for such services, where factors including offending behaviour and longer term care can have an influence. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: The importance of acknowledging and addressing responses related to offending behaviour in forensic mental health settings, while also understanding the vulnerability of the consumer group and responsibilities to the maintenance of professional boundaries. Enhancing collaboration with consumers/families/carers/supporters is important in a forensic mental health setting, and an important element of Safewards Secure.

WHAT IS KNOWN ON THE SUBJECT?: Seclusion is a harmful and traumatising intervention for people accessing mental health services. People who are subject to seclusion in inpatient mental health services often first experience this within the first 24 h following admission. There is limited research examining how recent contact with services impacts the likelihood of seclusion when people are admitted to inpatient services.

Aim: The research aim of this study was to seek feedback from prevention of aggression training experts about the suitability of Entrustable Professional Activities (EPAs) as an assessment tool for an Aggression Prevention Protocol. The protocol was designed to structure intervention to prevent aggression and reduce the use of restrictive practices following risk assessment using a validated instrument (the Dynamic Appraisal of Situational Aggression).

Background: Preventing aggression and limiting the use of restrictive practices are key priorities for inpatient mental health services.

Background: People with serious mental illness (SMI; bipolar [BD] or schizophrenia spectrum disorders [SSD]) who smoke have 30-60% lower odds of quitting and are more prone to experience neuropsychiatric adverse events (NPSAEs) when quitting than smokers without SMI. We pilot-tested the feasibility of combining two different dosing strategies of varenicline preloading with Acceptance and Commitment Therapy (ACT) in persons with SMI in an attempt to bolster quit rates without increasing NPSAEs.

Methods: Twelve-week, single center, randomized, double-blind, pilot feasibility trial of low (0.

Imipramine is a tricyclic antidepressant typically reserved for patients with treatment-resistant mood disorders. A rare side effect of long-term use of imipramine is a slowly progressive melanin-associated, slate gray-blue hyperpigmentation of the skin in a photo-distributed pattern. We report a case of imipramine-induced hyperpigmentation developing 50 years after initiating imipramine therapy, whose lesions were essentially devoid of melanin on histopathological exam.

Article Synopsis
  • The study investigates the impact of maternal childhood trauma on the mental health of their offspring, highlighting that while many children show increased psychopathology, some exhibit resilience.
  • It explores the role of epigenetic aging—measured through DNA methylation—in moderating the effects of maternal childhood adversity, particularly focusing on self-reported experiences of trauma.
  • Results reveal that while maternal sexual abuse is linked to offspring symptoms, this relationship diminishes in children who display accelerated epigenetic aging, suggesting a mechanism for resilience against intergenerational trauma.

The minimization of pain in research animals is a scientific and ethical necessity. Carprofen is commonly used for pain management in mice; however, some data suggest that the standard dosage of 5 mg/kg may not provide adequate analgesia after surgery. We hypothesized that a higher dose of carprofen in mice would reduce pain-associated behaviors and improve analgesia without toxic effects.

Patients with severe uncontrolled asthma (SUA) overwhelmingly contribute to the economic burden of asthma and may require biologic therapy. However, the impact of the CoronaVirus Disease of 2019 (COVID-19) on asthma costs and biologic use has yet to be evaluated. The objective was to test the hypothesis that SUA costs and biologic use decreased during the pandemic.

Recent evidence suggests that maternal childhood adversity may have an intergenerational impact, with children of adversity-exposed mothers exhibiting elevated symptoms of psychopathology. At the same time, many children demonstrate resilience to these intergenerational effects. Among the variety of factors that likely contribute to resilience, the composition of the gut microbiome may play a role in buffering the negative impacts of trauma and stress.

Necrobiosis lipoidica (NL) is a rare, chronic idiopathic granulomatous dermatitis with a somewhat controversial association with diabetes and other systemic diseases. We report a case of NL developing within a polychromic tattoo on the lower leg of a 53-year-old woman. Characteristic histopathologic findings of both active and chronic "burnt-out" NL appeared to originate from the tattoo where red ink was used 13 years prior.

Introduction: Contemporary models of care for people with mental disorders continue to shift to community-based care, requiring fewer inpatient mental health beds, shorter inpatient lengths of stay, and less use of coercion. It has been suggested that some mentally unwell people, whose behavior can no longer be safely contained in overstretched mental health units where seclusion and restraint are discouraged, are now left to the criminal justice system to manage. It is unclear whether the risk of imprisonment following discharge from a mental health unit has increased over recent years.

The concentration, chemical speciation, and spatial distribution of essential and toxic mineral elements in cereal seeds have important implications for human health. To identify genes responsible for element uptake, translocation, and storage, high-throughput phenotyping methods are needed to visualize element distribution and concentration in seeds. Here, we used X-ray fluorescence microscopy (μ-XRF) as a method for rapid and high-throughput phenotyping of seed libraries and developed an ImageJ-based pipeline to analyze the spatial distribution of elements.

Article Synopsis
  • Black American women face unique adversities that can negatively affect their mental health and potentially impact their children's well-being across generations.
  • The study analyzed 180 Black American mothers, looking at how their past trauma and experiences with racial discrimination might affect their children's emotional health, using both self-reports and biological measures.
  • Results showed that more childhood trauma, experiences of racial discrimination, and epigenetic age acceleration in mothers were linked to higher emotional reactivity in their children, highlighting the need to consider broader social factors when assessing "maternal adversity."*
