A 24-year-old man on maintenance hemodialysis presented with bilateral cavitary consolidations and methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia following ulceration of the skin over his arteriovenous (AV) fistula cannulation site. A diagnosis of septic pulmonary embolism was made, which presumptively originated from a localized MSSA infection of his AV access. He had an excellent response to a 28-day course of cloxacillin, with the resolution of the pulmonary lesions.Levels of environmental mercury (Hg) within the Canadian Arctic are a current area of concern. Although efforts have been made to reduce Hg released into the environment, levels remain elevated in flora and fauna. This study examined the concentrations of Hg in soil and naturally occurring edible plant and fungi species, identified by local Inuit residents, from eight locations in Iqaluit, Nunavut, and the surrounding area during the summers of 2018 and 2019. Total Hg concentrations were obtained in 24 soil samples, 112 flora samples from 23 plant and five lichen species, and 157 fungal samples from eight species. Median Hg concentrations in plant species ranged from 0.005 μg g-1 Hg dry weight (dw) in Saxifraga cernua to 0.19 μg g-1 Hg dw in Oxytropis maydelliana. Median concentrations in edible fungi species ranged from 0.084 μg g-1 Hg dw in the Cortinarius croceus (non-puffball species) to 1.6 μg g-1 Hg dw in Lycoperdon perlatum (a puffball mushroom). Additionally, median Hg concentration in puffball species (1.4 μg g-1 ) were higher than non-puffball species (0.12 μg g-1 ). Three puffball species were assessed for methylmercury (MeHg), with mean concentrations ranging from 0.013 to 0.085 μg g-1 MeHg dw. Limited research has been conducted on Hg uptake in naturally occurring edible plant and fungi species of the Canadian Arctic. This study contributes important information on Hg accumulation and processes in edible plant and fungi Arctic species, is the first to focus on plants used by the local Indigenous community, and demonstrates a need for further studies to assess Hg in Arctic environments.Globally, trans and gender diverse people contend with day-to-day exclusion, discrimination, and marginalisation, often culminating in experiences of poverty and homelessness. In this discussion article, we outline a bricolage research orientation rooted in liberation and Indigenous approaches brought into dialogue with the broader cannon of community psychology for meaningful research with homeless trans and gender diverse people. Such an approach transcends rigid disciplinary divides and shapes a framework for collaborative action, advocacy, and social change. We argue that scholar-activism, social justice, and relationality and collaboration should inform every stage of the research process and beyond when engaging with minoritized communities.
Intensified job demands (IJDs) and their effects on employee burnout, work engagement and patient satisfaction were investigated across different work units and occupational groups in a healthcare setting.
A multilevel study.
One thousand twenty-four healthcare employees responded to a survey in 2019 and rated their experiences of IJDs, burnout and work engagement. Nine hundred fifty-one patients rated their satisfaction with care received from healthcare staff.
Work units and occupational groups who shared more experiences of increased time pressure and multitasking reported higher exhaustion. LOXO-292 c-RET inhibitor Shared perceptions of increased planning and performing one’s work autonomously correlated with higher exhaustion and lower patient satisfaction at the work-unit level. Moreover, work intensification was found to be highest in emergency care and among nurses, while job-related planning demands were highest in leadership services.
IJDs are a shared risk to employee well-being among heterogeneous healthcare starating pace of socio-economic change, the pace of work is also getting faster. Our findings help understand how IJDs are experienced among heterogeneous healthcare staff. Because different occupational groups and work units had different demands, this research shows that attempts to mitigate the negative effects of IJDs need to be planned and implemented in a context-specific way. It seems crucial to pay more attention especially to adequate nurse staffing so that the adverse effects of IJDs could be mitigated among them.In a green energy economy, electrocatalysis is essential for chemical energy conversion and to produce value added chemicals from regenerative resources. To be widely applicable, an electrocatalyst should comprise the Earth’s crust’s most abundant elements. The most abundant 3d metal, iron, with its multiple accessible redox states has been manifold applied in chemocatalytic processes. However, due to the low conductivity of FeIII Ox Hy phases, its applicability for targeted electrocatalytic oxidation reactions such as water oxidation is still limited. Herein, it is shown that iron incorporated in conductive intermetallic iron silicide (FeSi) can be employed to meet this challenge. In contrast to silicon-poor iron-silicon alloys, intermetallic FeSi possesses an ordered structure with a peculiar bonding situation including covalent and ionic contributions together with conducting electrons. Using in situ X-ray absorption and Raman spectroscopy, it could be demonstrated that, under the applied corrosive alkaline conditions, the FeSi partly forms a unique, oxidic iron(III) phase consisting of edge and corner sharing [FeO6 ] octahedra together with oxidized silicon species. This phase is capable of driving the oxyge evolution reaction (OER) at high efficiency under ambient and industrially relevant conditions (500 mA cm-2 at 1.50 ± 0.025 VRHE and 65 °C) and to selectively oxygenate 5-hydroxymethylfurfural (HMF).Indoor air quality is a major issue for public health, particularly in northern communities. In this extreme environment, adequate ventilation is crucial to provide a healthier indoor environment, especially in airtight dwellings. The main objective of the study is to assess the impact of ventilation systems and their optimization on microbial communities in bioaerosols and dust in 54 dwellings in Nunavik. Dwellings with three ventilation strategies (without mechanical ventilators, with heat recovery ventilators, and with energy recovery ventilators) were investigated before and after optimization of the ventilation systems. Indoor environmental conditions (temperature, relative humidity) and microbiological parameters (total bacteria, Aspergillus/Penicillium, endotoxin, and microbial biodiversity) were measured. Dust samples were collected in closed face cassettes with a polycarbonate filter using a micro-vacuum while a volume of 20 m3 of bioaerosols were collected on filters using a SASS3100 (airflow of 300 L/min).
