Development of a new reference material for accurate measurements of lithium in Li-clays.

Currently, there are no national and international certified reference materials (CRM) in lithium clays that can make reliable and traceable lithium measurements for the International System of Units (SI). Hence, it is necessary to have references to meet the needs in terms of mining and activities that involve the use of lithium to favor the economy derived from its multiple uses and associated benefits in the exploration, exploitation, and handling of lithium ore. In this study, a candidate for reference material (RM) of Li in clays was developed and certified based on the provisions of ISO 17034:2016 and ISO Guide 35:2017. Different mass sizes of the RM (0.05, 0.1, and 0.25 g) were used to evaluate homogeneity. An isochronous study (short-term stability) was carried out in the assessment of stability, influenced by the effects of transport at different temperatures (20, 40, and 50 °C) for a determined time of 6 weeks, in addition to a classic (long-term) study for 19 weeks. The sample was treated using microwave-assisted acid digestion and Li measurements were performed using the analytical technique of Flame Atomic Absorption Spectrometry (FAAS). The CRM is homogeneous for the sample mass sizes of 0.05 and 0.1 g, and the mass fraction of w(Li) was stable in the RM for temperatures of 20, 40, and 50 °C. The determined period of validity was 3 years.

Certified Food Safety Management Systems Assessed through the Lenses of Food Safety Culture and Locus of Control: A Pilot Study.

The approach to ensure food safety (FS) has evolved, including the concept of FS culture, which has been shaped by both the legislation and the scientific literature. In this study, two companies that produce foods associated with potential risks of cross-contamination (gluten-free foods and frozen pastry, respectively) and are certified according to international voluntary FS standards, such as the British Retail Council Global Standard (BRC) and the International Featured Standards Food Version (IFS), were investigated to assess: (a) if the assessment of FS culture's pillars can uncover unexpected critical areas; (b) if the scores of the FS culture's pillars are related to personal traits, namely, age, seniority in the company and locus of control orientation, i.e., the beliefs that an event is the result of external factors (luck, destiny or superior beings), or the result of internal factors (human behavior). Questionnaires for the survey and the scoring system applied were selected from the literature. Results showed that all food handlers had an optimistic bias, which paradoxically could be the consequence of the rigorous application of hygienic procedures. The younger food handlers had significantly (p < 0.05) lower commitment than the older ones. Moreover, the segment of food handlers having an external locus orientation demonstrated weaker normative beliefs than those having an internal locus of control orientation. Results showed that the FS culture survey, which is related to the shared FS culture, could disclose unknown weakness in third-party certified companies, even if the well implemented principles of voluntary FS standards are aligned with the FS-culture pillars. Moreover, the segmentation of food handlers according to their age and the locus of control assessment could provide additional information on the individual orientation toward FS behavior. Hence these tools could assist the leaders in the management of the dynamic nature of human capital.

The evolution and formalization of anesthesia assistant roles across Canada.

PURPOSE: The purpose of this Special Article is to document the evolution of the anesthesia assistant (AA) profession in Canada and summarize AA practice at Canadian institutions as it exists today, five decades after Quebec and 15 years after most other provinces formalized AA practice. SOURCE: Through the Management Committee of the Association of Canadian University Departments of Anesthesia (ACUDA), we conducted a purposeful sampling of all ACUDA chairs or their delegates. We requested the following data: history of AAs becoming a reality in their particular province or region; potential recruitment pools; training programs and curricula; pathway to credentialing; funding, pay, retention, recruitment, and status of union representation; and metrics. PRINCIPAL FINDINGS: Data were provided by 19 institutions in 8 provinces: Newfoundland and Labrador, Nova Scotia, Quebec, Ontario, Manitoba, Saskatchewan, Alberta, and British Columbia. Given the different health care governance structures across the provinces, AA roles vary in terms of its associated technical, clinical, and educational responsibilities. The role of AAs in supporting anesthesia care through equipment maintenance and assistance with airway management, resuscitation, and administration of regional anesthesia seems to be well established, as is their role in providing brief intraoperative relief for anesthesiologists during a stable period of anesthesia. Anesthesia assistant duties continue to evolve, becoming more aligned with the specific institution and less dependent on the supervising anesthesiologist. Apart from the initial metrics collected during the Ontario ACT implementation pilot projects, we are not aware of any formal metrics, current or ongoing, being collected across Canada, related to either patient safety events or perioperative efficiency. CONCLUSIONS: This compilation of pan-Canadian AA data shows diverse models of practice and highlights the value to patients and the health care system as a whole of incorporating these allied professionals into the anesthesia care team (ACT). The present findings allow us to offer suggestions for consideration during discussions of retention, recruitment, program expansion, and cross-country collection of metrics and other data. We conclude by making six recommendations: 1. recognize that implementation of ACTs is a key element in solving the challenge of an increasing surgical backlog; 2. develop, or facilitate the development of, metrics and increase data-sharing nationally to enable health care authorities to better understand the importance of AAs in patient safety and perioperative efficiency; 3. develop and implement funding strategies to lower the barriers to AA training such as hospital-sponsored positions, ongoing salary support, and return-of-service arrangements; 4. ensure that salaries appropriately reflect the increased level of training and added levels of responsibility of certified AAs; 5. develop long-term strategies to ensure stable funding, recruitment and retention, and a better match between the number of AA training positions and the need for newly certified AAs; and 6. engage all stakeholders to acknowledge that AAs, as knowledgeable and specifically trained assistants, not only fulfill their defined clinical role but also contribute significantly to patient safety and clinical efficiency by assuming nondirect patient care tasks.

RéSUMé: OBJECTIF: Le but de cet article spécial est de documenter l'évolution de la profession d'assistant·e en anesthésie (AA) au Canada et de résumer la pratique des AA dans les établissements canadiens telle qu'elle existe aujourd'hui, cinquante ans après que le Québec et quinze ans après que la plupart des autres provinces ont officialisé la pratique des AA. SOURCES: Par l'entremise du Comité de gestion de l'Association canadienne universitaire des départements d'anesthésie (ACUDA), nous avons réalisé un échantillonnage ciblé de tou·tes les président·es de l'ACUDA ou de leurs délégué·es. Nous avons demandé les données suivantes : historique de la concrétisation de la profession d'AA dans leur province ou région; bassins de recrutement potentiels; programmes de formation et programmes d'études; voie d'accès à l'accréditation; financement, rémunération, rétention, recrutement et état de la représentation syndicale; et données métriques. CONSTATATIONS PRINCIPALES: Des données ont été fournies par 19 institutions dans 8 provinces : Terre-Neuve-et-Labrador, Nouvelle-Écosse, Québec, Ontario, Manitoba, Saskatchewan, Alberta et Colombie-Britannique. Compte tenu des différentes structures de gouvernance des soins de santé dans les provinces, les rôles des AA varient en termes de responsabilités techniques, cliniques et éducatives connexes. Le rôle des AA dans le soutien des soins d'anesthésie par l'entretien du matériel et l'aide à la prise en charge des voies aériennes, à la réanimation et à l'administration de l'anesthésie régionale semble bien établi, tout comme leur rôle dans la fourniture d'un bref soulagement peropératoire aux anesthésiologistes pendant une période stable d'anesthésie. Les tâches des assistant·es en anesthésie continuent d'évoluer, devenant plus alignées sur l'établissement spécifique et moins dépendantes de l'anesthésiologiste superviseur·e. À l'exception des mesures initiales recueillies dans le cadre des projets pilotes de mise en œuvre des ESA (équipes de soins en anesthésie) en Ontario, nous ne sommes au courant d'aucune mesure officielle, actuelle ou en cours, recueillie dans l'ensemble du Canada, concernant les événements liés à la sécurité des patient·es ou à l'efficacité périopératoire. CONCLUSION: Cette compilation de données pancanadiennes sur les AA présente divers modèles de pratique et souligne l'importance pour les patient·es et le système de soins de santé dans son ensemble d'intégrer ces professionnel·les connexes à l'équipe de soins d'anesthésie (ESA). Les résultats actuels nous permettent d'avancer des suggestions à prendre en compte lors des discussions sur le maintien en poste, le recrutement, l'expansion des programmes et la collecte de mesures et d'autres données à l'échelle du pays. Nous concluons en formulant six recommandations : 1. reconnaître que la mise en œuvre des ESA constitue un élément clé pour résoudre le problème de l'augmentation de l'arriéré chirurgical; 2. élaborer ou faciliter l'élaboration de mesures et accroître le partage des données à l'échelle nationale pour permettre aux autorités sanitaires de mieux comprendre l'importance des AA pour la sécurité des patient·es et l'efficacité périopératoire; 3. élaborer et mettre en œuvre des stratégies de financement pour réduire les obstacles à la formation des AA, comme les postes parrainés par les hôpitaux, le soutien salarial continu et les ententes de retour de service; 4. veiller à ce que les salaires reflètent de manière appropriée le niveau accru de formation et les niveaux de responsabilité accrus des AA certifié·es; 5. élaborer des stratégies à long terme pour assurer un financement, un recrutement et une rétention stables, ainsi qu'une meilleure adéquation entre le nombre de postes de formation des AA et le besoin de nouveaux et nouvelles AA certifié·es; et 6. inciter toutes les personnes impliquées à reconnaître que les AA, en tant qu'assistant·es compétent·es et spécialement formé·es, non seulement remplissent leur rôle clinique défini, mais contribuent également de manière significative à la sécurité des patient·es et à l'efficacité clinique en assumant des tâches de soins non directs aux patient·es.

Pre-Admission Standardized Tests and the Relationship with Anesthesiologist Assistant Student Performance: A Retrospective Analysis.

Background: The Anesthesiologist Assistant (AA) profession is gaining popularity, and as such, the number of applicants and the number of AA programs are also increasing. There is no published data on what makes a good AA student - multiple studies exist in this regard for anesthesiology residents and medical students. The Medical College Admissions Test (MCAT) and the Graduate Record Examination (GRE) have shown to have some correlation with student success in other health professions. There is no data to suggest that they can indicate potential success or academic problems during AA school. As such, this study evaluated the impact of these standardized test scores and student success in both the preclinical and clinical curricula at the Emory AA program. Methods: A retrospective analysis of MCAT scores and GRE scores was performed. 2-tailed Pearson coefficients were calculated to see if there was a relationship between higher MCAT and GRE scores and performance in our program. Results: 2- tailed Pearson coefficients showed a moderately strong correlation between MCAT scores and our AA program's science curriculum. There was a weak correlation as well between GRE scores here. The correlation dropped slightly for the MCAT and performance during our clinical curriculum, and a similar drop was noted for the GRE. Discussion: Our study shows that the MCAT appears to more strongly correlated with better performance in both the science curriculum of our program and also with our clinical program. The study likely implies that the MCAT appears to be a better gauge as to how a student will do in an AA program in comparison to the GRE. Further studies are needed to understand how to appropriately admit students who will successfully complete the rigorous AA program curriculum both at Emory and beyond.

In the presence of death and dying: death attitudes and compassion fatigue among certified nursing assistants in skilled care.

OBJECTIVES: Certified Nursing Assistants (CNAs) are responsible for 80-90% of direct-to-resident care in skilled nursing facilities (SNFs), and may develop close, family-like relationships with their residents. With SNFs becoming a common place of death for older adults, CNAs now find themselves engaging in end-of-life caregiving with limited training and institutional support for emotional outcomes. This study aimed to understand and evaluate the relations between bereavement, death exposure, and compassion fatigue among CNAs, hypothesizing that (a) experiential avoidance moderates the relation between death exposure and negative death attitudes and (b) death attitudes moderate the relation between death exposure and compassion fatigue. METHOD: One hundred and ten CNAs across all shifts from four skilled nursing facilities in the southeastern United States participated in surveys and, potentially, focus groups. RESULTS: Results failed to find support for death exposure being related either to experiential avoidance or negative death attitudes. However, results supported the relation between negative death attitudes and compassion fatigue. CONCLUSION: Implications highlight the need to develop interventions focusing on palliative skills-based training and emotional support of CNAs in their role as end-of-life caregivers. By reducing compassion fatigue, it may be possible to decrease job turnover and increase quality-of-care for residents.

Change in expectations: A policy recommendation for future and current nurse educators.

Currently, there are no standardized requirements for pedagogical preparation for nurse educators at the state and national level. Various stakeholders have identified an issue in the preparation of nurse educators in academia. Current recommendations are that faculty have a master's or doctoral degree in nursing (American Association of Colleges of Nursing, 2017); however, requirements do not include educational preparation prior to or concurrent with starting a faculty position. This policy paper highlights a recommendation to require one of the following: the Certified Nurse Educator credential or certificate in teaching for educators without prior formal education in pedagogy. Outcomes of such a requirement would include nurse educators have a better understanding of the science of nursing education and preparation related to teaching. A second outcome is students receive an education that uses evidence-based teaching methods.

Training potential of a teleoperated humanoid robot for use by a young psychiatrist during childcare leave.

Background: Childcare leave extensions can sometimes negatively affect the professional clinical training of early-career psychiatrists in Japan. During childcare leave, being able to learn in the examination room while staying at home would be useful. Therefore, we developed a training system using a teleoperated robot (Sota) for young psychiatrists who wanted to participate in the examination room during childcare leave while remaining at home. Case Presentation: We report the case of a patient with autism spectrum disorder (ASD) comorbid with Tourette's disorders (P). A young female psychiatrist (D) used the training system to learn from a board-certified psychiatrist. In this case, the board-certified psychiatrist, P, and the robot were placed in the examination room. D teleoperated Sota from home, allowing her to talk to the board-certified psychiatrist and P. She learned about the clinical features of Tourette's syndrome by observing the examination of the board-certified psychiatrist and hearing the patient's distress. P was satisfied with the fact that he was seen not only by a board-certified psychiatrist but also by D. Conclusion: These case findings suggest that our system is helpful for young psychiatrists who want to study in the examination room during childcare leave while staying at home. Future studies should include a single-case experimental design with information regarding key outcome variables and other relevant variables gathered regularly over time.

Development of purity certified reference materials to establish metrological traceability for the measurement of nitroimidazoles in agricultural products.

It is of significant importance to public health that reliable monitoring of nitroimidazoles be conducted, while certified reference materials (CRMs) are essential for accurate and reliable detection. A project has been initiated with the objective of developing nitroimidazole purity CRMs to ensure that results from nationwide monitoring laboratories for nitroimidazoles in antibiotic residues can be compared and traced. The candidates were successively characterized in terms of their structure by means of infrared (IR) spectroscopy and mass spectrometry (MS). The mass balance (MB) method and the quantitative nuclear magnetic resonance (qNMR) method were utilized to determine the purity of nitroimidazoles with remarkable accuracy. Furthermore, a methodical investigation was conducted on homogeneity, stability, and uncertainty. Six nitroimidazole purity CRMs, including tinidazole (GBW09252), secnidazole (GBW09286), ronidazole (GBW09288), metronidazole (GBW(E)090755), dimetridazole (GBW(E)090819), and ornidazole (GBW(E)090820), were finally manufactured following authorization from China's State Administration for Market Regulation (SAMR). By using these CRMs, it is possible to improve the traceability, accuracy, and comparability of nitroimidazole measurements in a range of agricultural products, protecting public health.

Private sector led multi-stakeholder platforms positively influence certified common bean seed supply in Malawi.

Common bean yields in Malawi remain low, primarily due to the use of low-yielding, recycled local seeds by most smallholder farmers. The low uptake of certified bean seed is attributed to limited incentives from the private sector. This study hypothesizes that the sustainable adoption of market-preferred varieties can be achieved by synchronizing and linking seed production to the grain market through committed value chain actors in a private sector-led multi-stakeholder platform. This paper examines the role of private sector-led multi-stakeholder platforms in the supply of certified common bean seed in Malawi. The research draws on both qualitative and quantitative primary data collected through a semi-structured questionnaire and interviews with key informants. Data were analyzed using an Ordinary Least Squares (OLS) regression model. The results indicate that several variables representing membership in multi-stakeholder platforms (MSPs) significantly affect the supply of certified common bean seed. Participation in MSPs, contractual arrangements, market structure, extension services, and seed demonstrations positively influenced seed supply. The findings underscore the need for a well-coordinated multi-stakeholder platform to enhance the supply of certified common bean seed, supported by effective policies and incentives from policymakers.

Total organic carbon quantification in soils and sediments: Performance test of a modified sample preparation method.

The total organic carbon (TOC) concentration of particulate samples is a key parameter to characterize soils and sediments. To demonstrate the applicability and reliability of a modified sample preparation method for the direct measurement of TOC contents in suspended particulate samples, we analyzed five certified reference materials (CRMs) with varying TOC concentrations using a Shimadzu TOC-L CPH analyzer. Measured values were calibrated with a multi-point curve that cover the full range of the expected TOC concentrations and the results were validated using statistical values and measures. The method validation reveals that the measurements are accurate and precise for CRMs from marine and soil contexts, but show a low accuracy for the CRM containing polycyclic aromatic hydrocarbons (PAHs). This demonstrates the applicability and reliability of the modified preparation method for direct TOC determination of suspended particulate samples. Therefore, it is relevant for a broader community, beyond geosciences, and for users employing devices of other manufacturers to analyze TOC in suspended particulate samples.•Modified preparation method uses reduced sample weights and yields accurate and precise results.•Cost-efficient and environmentally friendly alternative: reduces waste by saving acid and ultrapure water.•Avoids incomplete dissolution of dolomite by heating acidified samples.
