RESUMO
BACKGROUND: Chronically hospitalized children are at risk for neurodevelopmental delay, compounded by restricted social interactions, movement and environmental stimulation. We measured patients' movements and interactions to characterize developmentally relevant aspects of our inpatient environment and identify opportunities for developmental enrichment. METHODS: As part of a quality improvement initiative to inform neurodevelopmental programming for children with medical complexity at our paediatric post-acute care specialty hospital, we conducted >232 hours of time-motion observations. Trained observers followed 0- to 5-year-old inpatients from 7 am to 7 pm on weekdays, categorizing observations within five domains: Where, With, Position, State and Environment. Observations were collected continuously utilizing REDCap on iPads. A change in any domain initiated a new observation. RESULTS: Patients were median 1 year and 8 months of age (range 2 months to 3 years 9 months) with a median length of hospitalization of 514 days (range 66-1298). In total, 2636 unique observations (or median 134 observations per patient-day [range 95-210]) were collected. Patients left their rooms up to 4 times per day for median 1 h and 34 min (range 41 min to 4 h:30 min). Patients spent 4 h:6 min (2 h:57 min to 6 h:30 min) interacting with someone and 3 h:51 min (57 min to 6 h:36 min) out of bed each day. Patients were simultaneously out of their beds, interacting with someone and awake for 2 h:21 min (51 min to 4 h:19 min) each day. CONCLUSIONS: Despite a care model prioritizing time out of bed and social interaction, time-motion observations indicate patients spent many of their waking hours in bed and alone. Quantifying our inpatients developmental opportunities will inform neurodevelopmental programming initiatives.

Nursing education, as with professionalization projects, is fraught with epistemicide, false separations, and a focus on expertise over relations and accountability. This is a critical reflection of the first 5 years of a four-semester prelicensure Community Engagement course series. As the course lead, I have consistently initiated adjustments, based on experiences teaching multiple sections and synthesizing comments and feedback from students and faculty, with an eye toward longstanding and pressing concerns in the world around us. Two broad epistemic arrangements emerge from this critical excavation: (1) naturalized hierarchy, false separations, and appraisals of relevance and (2) relationality and reflection as unsettling. There is a need for sustained collective examination and shift in how the nursing education and healthcare industries curate the meanings and practice of "community," "health," and "nursing," peering out from the regulatory oversight of neoliberal forces. How might we situate student progression, program implementation, institutional contracts, and curricular standards within the contexts of nursing programs' responsibilities to local communities in light of unfolding events locally and globally and their historical antecedents? How are we all, as faculty, disrupting siloes, false separations, and the contradictions of professionalism and the biomedical model to intentionally advance health equity? May we continue to illuminate the presence of community as being everywhere, not merely in juxtaposition to acute care. May we unsettle the prevailing theorization and practices of community throughout nursing education and commit to imagining and practicing relational praxis.
RESUMO
BACKGROUND: Although health equity is critically important for healthcare delivery, there are inconsistencies in its definitions or lack of definitions. PURPOSE: Develop a comprehensive understanding of health equity to guide nursing practice and healthcare policy. METHOD: Walker and Avant's concept analysis method was used to establish defining attributes, antecedents, consequences, and empirical referents of health equity. FINDINGS: Health equity defining attributes are grounded in ethical principles, the absence of unfair and avoidable differences, and fair and just opportunities to attain a person's full health potential. Health equity antecedents are categorized into environmental; financial or economic; law, politics, and policy; societal and structural; research; and digital and technology. DISCUSSION: Health equity's antecedents are useful to distinguish health disparities from health outcomes resulting from individual preferences. To achieve health equity, organizations need to focus on addressing the antecedents.

Scholars of color have been instrumental in advancing nursing knowledge development but find limited spaces where one can authentically share their philosophical perspective. Although there is a call for antiracism in nursing and making way for more diverse and inclusive theories and philosophies, our voices remain at the margins of nursing theory and philosophy. In nursing philosophy, there continues to be a lack of racial diversity in those who are given the platform to share their scholarship. Five nurse scholars of color attended the International Nursing Philosophy Conference in August 2022. We established a collective system of support by sharing our experiences as researchers, scholars, and educators with each other. The theory of emancipatory nursing praxis informed this process. In this dialogue, we reflected on what it is like to present at and attend predominantly white nursing conferences. We shared our experiences of how we exist as nurse scholars, our philosophical views, and our thoughts on how we create spaces where scholars of color can feel welcomed and acknowledged for their contributions to advancing nursing knowledge.
RESUMO
Drawing from a keynote panel held at the hybrid 25th International Philosophy of Nursing Conference, this discussion paper examines the question of epistemic silence in nursing from five different perspectives. Contributors include US-based scholar Claire Valderama-Wallace, who meditated on ecosystems of settler colonial logics of nursing; American scholar Lucinda Canty discussed the epistemic silencing of nurses of colour; Canadian scholar Amelie Perron interrogated the use of disobedience and parrhesia in and for nursing; Canada-based scholar Ismalia De Sousa considered what nursing protects in its silences; and Australian scholar Janice Gullick spoke to trans invisibility in nursing.
RESUMO
Social justice is put forth as a core professional nursing value, although conceptualizations within foundational documents and among nurse educators remain inconsistent and contradictory. The purpose of this study was to explore how faculty teach social justice in theory courses in Baccalaureate programs. This qualitative study utilized constructivist grounded theory methods to examine processes informing participants' teaching. Participants utilize four overarching approaches: fostering engaging classroom climates, utilizing various naming strategies, framing diversity and culture as social justice, and role modeling a critical stance. They deploy specific strategies, varying largely by race, educational background, and nursing specialty. A background in social sciences supports pedagogy that interrogates health inequities rather than merely raising awareness about disparities. Findings also reveal that faculty of color navigate institutional structures predicated upon colorblind racism and problematic views of culture, which many white faculty teaching non-Community Health Nursing courses described doing. To enact social justice and be answerable to our communities, concerted anti-oppression efforts are needed across education, research, practice, and policy. This includes sustained commitment to address colonialism and whiteness in every institution that defines, promotes, and claims to advance nursing so that we can fulfill our responsibility to address unjust systems and structures to serve our communities.

OBJECTIVE: The purpose of this study was to explore nurse educators' conceptualizations of social justice in theory courses. The findings contextualize the role of nurse educators in promoting social justice among future health care providers and the relevance of their perspectives on social justice. DESIGN: This descriptive qualitative study was completed utilizing constructivist grounded theory methods. SAMPLE AND MEASUREMENTS: I interviewed 28 nurse educators teaching theory courses in Baccalaureate nursing programs on the West coast of the United States. Initial and focused codes were constructed from interview transcripts to understand and contextualize statements about social justice. RESULTS: Participants' conceptualizations of social justice include equity, equality, self-awareness, withholding judgment, and taking action. CONCLUSIONS: Notable differences emerged along racial lines and, less so, in relation to educational background and nursing specialty. This study highlights areas of concern with respect to how nurse educators enact the claim that social justice is a core professional nursing value. The findings call attention to tensions and contradictions as individuals navigate the landscape of nursing with limited structural and institutional effort.

Despite institutional claims that social justice is a core professional nursing value, efforts to fulfill this claim remain uneven. The purpose of this study was to examine the circumstances that shape nursing educators' approaches to social justice. In-depth semi-structured interviews with 28 educators teaching theory courses in baccalaureate nursing programs shed light upon the influences that shape how educators integrate social justice. These include formative experiences, institutional factors, and curricular opportunities. Formative experiences include upbringing, educational background, and preparation to teach. Institutional factors consist of the type of institution, geographic location, and the specter of retention, promotion, and tenure. Finally, curricular opportunities and fit include the positioning of Community Health Nursing, fragmentation and tension between "content and context," and the "driving force" of the National Council Licensure Examination for Registered Nurses (NCLEX). Findings indicate that the capacity to uphold the value of social justice is shaped by experiences across the lifespan, institutional policies, and practices related to faculty hiring, development, career advancement, as well as curricular vision. This study calls for a concerted effort to enact social justice nursing education.

OBJECTIVE: Social inequities threaten the health of the global population. A superficial acknowledgement of social justice by nursing's foundational documents may limit the degree to which nurses view injustice as relevant to nursing practice and education. The purpose was to examine conceptualizations of social justice and connections to broader contexts in the most recent editions. DESIGN: Critical discourse analysis examines and uncovers dynamics related to power, language, and inequality within the American Nurses Association's Code of Ethics, Scope and Standards of Practice, and Social Policy Statement. RESULTS: This analysis found ongoing inconsistencies in conceptualizations of social justice. Although the Code of Ethics integrates concepts related to social justice far more than the other two, tension between professionalism and social change emerges. The discourse of professionalism renders interrelated cultural, social, economic, historical, and political contexts nearly invisible. CONCLUSION: Greater consistency would provide a clearer path for nurses to mobilize and engage in the courageous work necessary to address social injustice. These findings also call for an examination of how nurses can critique and use the power and privilege of professionalism to amplify the connection between social institutions and health equity in nursing education, practice, and policy development.

The photoisomerization of ß-ionone protonated Schiff base (BIPSB) is investigated in the gas phase by irradiating mobility-selected ions in a tandem ion mobility spectrometer with tunable radiation. Four distinguishable isomers are produced by electrospray ionization whose structures are deduced from their collision cross sections and photoisomerization behavior along with density functional theory calculations. They include two geometric isomers of BIPSB with trans or cis configurations about the polyene chain's terminal CâN double bond, a bicyclic structure formed through electrocyclization of the polyene chain, and a Z-retro-γ-ionone isomer. Although trans-BIPSB and 9-cis-BIPSB have similar photoisomerization action spectra, with a maximum response at 375 nm, they photoconvert to different isomers. The trans-BIPSB isomer transforms to the bicyclic form upon exposure to light over the 320-400 nm range, whereas the cis-BIPSB isomer is prevented by steric hindrance from forming the bicyclic BIPSB isomer following irradiation and is proposed instead to form the 7,9-di-cis isomer. Neither the bicyclic isomer nor the Z-retro-γ-ionone isomer respond strongly to near-UV light.
RESUMO
Imidazopyridazine compounds are potent, ATP-competitive inhibitors of calcium-dependent protein kinase 1 (CDPK1) and of Plasmodium falciparum parasite growth in vitro. Here, we show that these compounds can be divided into two classes depending on the nature of the aromatic linker between the core and the R2 substituent group. Class 1 compounds have a pyrimidine linker and inhibit parasite growth at late schizogony, whereas class 2 compounds have a nonpyrimidine linker and inhibit growth in the trophozoite stage, indicating different modes of action for the two classes. The compounds also inhibited cyclic GMP (cGMP)-dependent protein kinase (PKG), and their potency against this enzyme was greatly reduced by substitution of the enzyme's gatekeeper residue at the ATP binding site. The effectiveness of the class 1 compounds against a parasite line expressing the modified PKG was also substantially reduced, suggesting that these compounds kill the parasite primarily through inhibition of PKG rather than CDPK1. HSP90 was identified as a binding partner of class 2 compounds, and a representative compound bound to the ATP binding site in the N-terminal domain of HSP90. Reducing the size of the gatekeeper residue of CDPK1 enabled inhibition of the enzyme by bumped kinase inhibitors; however, a parasite line expressing the modified enzyme showed no change in sensitivity to these compounds. Taken together, these findings suggest that CDPK1 may not be a suitable target for further inhibitor development and that the primary mechanism through which the imidazopyridazines kill parasites is by inhibition of PKG or HSP90.

A high throughput screen allowed the identification of N-hydroxyimide inhibitors of ERCC1-XPF endonuclease activity with micromolar potency, but they showed undesirable selectivity profiles against FEN-1. A scaffold hop to a hydroxypyrimidinone template gave compounds with similar potency but allowed selectivity to be switched in favour of ERCC1-XPF over FEN-1. Further exploration of the structure-activity relationships around this chemotype gave sub-micromolar inhibitors with >10-fold selectivity for ERCC1-XPF over FEN-1.

Catechol-based inhibitors of ERCC1-XPF endonuclease activity were identified from a high-throughput screen. Exploration of the structure-activity relationships within this series yielded compound 13, which displayed an ERCC1-XPF IC50 of 0.6 µM, high selectivity against FEN-1 and DNase I and activity in nucleotide excision repair, cisplatin enhancement and γH2AX assays in A375 melanoma cells. Screening of fragments as potential alternatives to the catechol group revealed that 3-hydroxypyridones are able to inhibit ERCC1-XPF with high ligand efficiency, and elaboration of the hit gave compounds 36 and 37 which showed promising ERCC1-XPF IC50 values of <10 µM.

PfCDPK1 is a Plasmodium falciparum calcium-dependent protein kinase, which has been identified as a potential target for novel antimalarial chemotherapeutics. In order to further investigate the role of PfCDPK1, we established a high-throughput in vitro biochemical assay and used it to screen a library of over 35,000 small molecules. Five chemical series of inhibitors were initially identified from the screen, from which series 1 and 2 were selected for chemical optimization. Indicative of their mechanism of action, enzyme inhibition by these compounds was found to be sensitive to both the ATP concentration and substitution of the amino acid residue present at the "gatekeeper" position at the ATP-binding site of the enzyme. Medicinal chemistry efforts led to a series of PfCDPK1 inhibitors with 50% inhibitory concentrations (IC50s) below 10 nM against PfCDPK1 in a biochemical assay and 50% effective concentrations (EC50s) less than 100 nM for inhibition of parasite growth in vitro. Potent inhibition was combined with acceptable absorption, distribution, metabolism, excretion, and toxicity (ADMET) properties and equipotent inhibition of Plasmodium vivax CDPK1. However, we were unable to correlate biochemical inhibition with parasite growth inhibition for this series overall. Inhibition of Plasmodium berghei CDPK1 correlated well with PfCDPK1 inhibition, enabling progression of a set of compounds to in vivo evaluation in the P. berghei rodent model for malaria. These chemical series have potential for further development as inhibitors of CDPK1.

The coronavirus pandemic provoked worldwide changes to the workplace, leading to rapid changes in lifestyles and working conditions. While organizations and governments struggled to develop regulations and policies, individuals were forced to find ways to manage work and life. During the pandemic and quarantine, a group of knowledge workers from around the world convened virtually and agreed to use qualitative autoethnographic methods to study how the quarantine disrupted their conventional patterns of work and care. In this article, we apply two communication perspectives-uncertainty reduction theory and re-silience-to participant diaries to understand how participants represent internal and external stressors, the efforts diarists employed to overcome those stressors, and their varying success in doing so. Post-hoc application of these communication concepts suggests that the diarists, though privileged in some ways, were not exempt from the social, professional, and emotional consequences of the pandemic and that their efforts to enact resilience were unevenly successful, especially in relation to their use of communications technology. Diarists reported struggling with uncertainty at numerous levels and that uncertainty contributed to individual emotional and cultural distress. Disruptions to work, home, and communities significantly affected wellbeing and ability to cope with challenges. Added to this were the complex and competing roles that diarists felt as they struggled to work from home, parent, and remain engaged.
RESUMO
For decades, health professional organizations have recommended increased diversity in the workforce and education. To address persistent inequities in health care, the racial composition of the nursing workforce needs be congruent with the U.S. population. Without first addressing structural inequity in nursing education programs, the nursing profession cannot begin to address structural racism in health care. The lack of nursing student diversity is reflective of barriers in program admissions. This article is a call to nursing accreditation bodies to operationalize anti-racism to improve U.S. nursing workforce diversity by introducing accountability structures that require evidence-based holistic admission review and analysis of admission data to ensure that student cohorts are diverse across nursing programs, thereby ensuring a future workforce that reflects the diversity of the U.S. population.
RESUMO
A series of imidazopyridazines which are potent inhibitors of Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1) was identified from a high-throughput screen against the isolated enzyme. Subsequent exploration of the SAR and optimisation has yielded leading members which show promising in vitro anti-parasite activity along with good in vitro ADME and selectivity against human kinases. Initial in vivo testing has revealed good oral bioavailability in a mouse PK study and modest in vivo efficacy in a Plasmodium berghei mouse model of malaria.

BACKGROUND: Two population surveys were conducted in Belarus: The Living Conditions, Lifestyle and Health (LLH) in 2001 (n = 2000) and The Health in Times of Transition (HITT) in 2010 (n = 1800). Each survey included a question on health status. The LLH questionnaire provided a 4-point Verbal Response Scale, but the HITT questionnaire used a 5-point scale. When translated into Russian, only two response categories of these scales had identical wording. These differences made a direct comparison of self-reported health status between 2001 and 2010 difficult. METHODS: We conducted a Health Category Response Scale (HCRS) survey in 2010 (n = 570) using a 100ths graduated Visual Analogue Scale (VAS) to understand how the response categories of different scales are perceived by Russian speakers. We implemented the HCRS survey's data to calculate the weighted health status (WHS) for each of the original surveys and to compare health status in Belarus between 2001and 2010. RESULTS: The WHS in Belarus showed a small, but statistically significant, improvement of 2.9 points on a 0-100 scale between 2001 and 2010 (56.2 vs. 59.1). Identical response categories were perceived differently on a 4-point and 5-point VAS. The category 'good' ('ХоÑоÑее') measured â¼12 points higher, and the category 'bad/poor' ('ÐÐ»Ð¾Ñ Ð¾Ðµ') measured â¼16 points lower, on the 4-point compared with the 5-point VAS. CONCLUSION: Our HCRS survey and novel method enabled a direct comparison of questions with different response options. When applied to the LLH and HITT projects, we concluded that health status in Belarus has improved between 2001 and 2010.

American institutions of nursing education have integrated cultural competence as a pillar approach to addressing health disparities. The theoretical frameworks, priorities, and solutions that national organizations pursue and endorse have far-reaching implications. The American Association of Colleges of Nursing (AACN) is one such organization. The purpose of this project was to critically analyze the AACN's Tool Kit of Resources for Cultural Competent Education for Baccalaureate Nurses to excavate dynamics related to language, power, and inequality. Findings of this critical discourse analysis indicate: (1) the centrality of the AACN's assumed authority and lack of relationality with readers, (2) nursing insularity and narrow theorization of culture and power, and (3) the harm of whiteness and colonialism as pedagogy. Accountability and repair include transparency, taking note of resources and viewpoints available and endorsed on organization websites, and updating (or refuting) outdated and harmful approaches.
RESUMO
The COVID lockdowns were characterised by new forms of governmentality as lives were disrupted and controlled through the vertical transmission of biopolitics by the state. The paper considers how this was experienced by academics in 11 different countries through analysis of diaries written during the first lockdown. The paper asks if communities can offer an alternative to governmentality by looking at three levels: the national, the neighbourhood and the personal. Whilst at a national level the idea of community was instrumentalised to encourage compliance to extraordinary measures, at the local level community compassion through helping neighbours encouraged horizontal connections that could offer a "space" within the dominant logic of governmentality. At the level of personal communities, the digitalisation of social relationships helped to create supportive networks over widely dispersed areas but these were narrowly rather than widely focused, avoiding critical discussion.
