The prevalence of Late-life Depression (LLD) has been estimated between 10% and 15%. Therefore, it is a considerable worldwide problem. The psychopathology is not substantially different from that of depressive episodes in young adults but somatic complaints in combination with end-of-life perspective leave an imprint on emotional experience. The frequent suicidal tendency, especially in old unmated men, remains a particular challenge. It is important to combine psychiatric and somatic diagnostics using modern meth [...]

Treatment options for end stage lung diseases are limited to stabilizing lung failure, decreasing disease progression, and symptom management, but significant reversal of lost lung function is often not possible. For well selected patients, lung transplantation may be a viable option to improve both longevity and quality of life. Though outcomes for lung transplant recipients have improved over several decades, long term survival still lags behind that of other solid organ transplant recipients. Longevity after lun [...]

The use of Pd-Cu bimetallic catalysts in the reduction of aqueous nitrate ions by hydrogen was studied. The catalysts were supported on multi-walled carbon nanotubes (MWCNTs), activated carbon (AC), and Titania, and the influence of the support on the nitrate reduction activity in water was then investigated. The catalysts were characterized before and after use by FT-IR, XRD, SEM, EDX, and Laser Granulometry. It was found that the surface characteristics of the support have an influence on the catalyst activity, w [...]

The Pd-H system has attracted extensive attention. Pd can absorb considerable amount of H at room temperature, this ability is reversible, so it is suitable for multiple energy applications. Pd-Ag alloys possess higher H permeability, solubility and narrower miscibility gap with better mechanical properties than pure Pd, but sulfur poisoning remains an issue. Pd-Cu alloys have excellent resistance to sulfur and carbon monoxide poisoning and hydrogen embrittlement, good mechanical properties, and broader temperature [...]

We explored the feasibility of a virtual-reality delivered mindfulness training intervention on burnout symptoms among corporate employees and clinicians in the Intensive Care Unit and Palliative Care Unit (PCU). To develop the VR mindfulness intervention we leveraged the Capability, Opportunity, Motivation, Behavior model (COM-B) as a guide for the design and implementation of the VR mindfulness training intervention. Using a pre-posttest within subjects design we assessed burnout syndrome, job stress and work-rel [...]

Musculoskeletal (MSK) pain is a multifaceted problem, with many contributors. The assessment of these contributions by clinicians has evolved to include not only the musculoskeletal and nervous systems, but also psychosocial contributions. Nutrition, however, has not been considered as a potential contributor in the same way, despite a significant body of evidence showing that amending one’s diet may significantly reduce pain and inflammation. Historically, when the biomedical model was considered the gold standard [...]

Background: The leaves of Mitragyna speciosa (kratom), a tropical tree that is indigenous to Southeast Asia, have been used traditionally to increase stamina, as a digestive aid, and as an analgesic. Kratom use is now increasingly popular in the rest of the world because of easy availability through the Internet and real, or perceived, views of efficacy and safety. Methods: PubMed and MedLine searches were conducted of published articles available in English. Results: Mitragynine and 7-hydroxymitragynine are the pr [...]

The experience of loss due to death, illness, and social mitigation was inevitable during the COVID-19 pandemic. Mental health services are chronically difficult to access in Canada, and this barrier is further exacerbated when trying to access certified art therapists to deliver expressive arts therapy. This pilot project attempted to provide an alternative to this service through an interprofessional alliance with a professional artist and certified counselors. A small group (n = 6) of vulnerable youth who had su [...]

In this perspective on hydrogen carriers, we focus on the needs for the development of robust active catalysts for the release of H2 from aqueous formate solutions, which are non-flammable, non-toxic, thermally stable, and readily available at large scales at reasonable cost. Formate salts can be stockpiled in the solid state or dissolved in water for long term storage and transport using existing infrastructure. Furthermore, formate salts are readily regenerated at moderate pressures using the same catalyst as for [...]

The first step in managing an entity's carbon emissions involves measurement as 'what gets measured gets managed' and measurement lies at the heart of carbon management. The study of carbon management is important to all stakeholders as it enables calculation of emissions that can help determine opportunities for emissions reductions to address climate change which can improve energy efficiency and brand reputation. Alphabet is an interesting company to study given its main commercial activities relate to the devel [...]
