Racial and ethnic diversity in academic nursing leadership: A cross-sectional analysis.

BACKGROUND/PURPOSE: To characterize the representation of racial and ethnic minoritized faculty in leadership positions at the top 50 National Institutes of Health-ranked academic nursing institutions. METHODS: We conducted a cross-sectional observational study to characterize the racial/ethnic composition of academic leaders, including those in diversity, equity, and inclusion (DEI) positions from September 2020 to December 2020. DISCUSSION: Among the 409 leaders, the sample was predominantly composed of females (86.6%), White leaders (80.9%), affiliated with public institutions (75.1%), and in the southern region (42.1%). Exactly 13.6% were from minoritized groups. Minoritized leaders were less likely to hold dean and higher executive positions than their nonminoritized counterparts (p < .002). DEI leadership positions were mostly concentrated in lower executive positions (e.g., director) and primarily consisted of minoritized leaders (>60%). CONCLUSION: Underrepresentation of racial and ethnic minoritized individuals in academic nursing leadership persists, necessitating structural interventions within nursing academia to promote inclusivity. Achieving this goal requires a concerted investment in diversifying academic nursing leadership and ensuring positions that minoritized leaders are in, hold weight.

Severe neighborhood deprivation and nursing home staffing in the United States.

BACKGROUND: Low nursing home staffing in the United States is a growing safety concern. Socioeconomic deprivation in the local areas surrounding a nursing home may be a barrier to improving staffing rates but has been poorly studied. Thus, the objective of this paper was to assess the relationship between neighborhood deprivation and nursing home staffing in the United States. METHODS: This cross-sectional study used 2018 daily payroll-based staffing records and address data for 12,609 nursing homes in the United States linked with resident assessment data. Our primary exposure of interest was severe economic deprivation at the census block group (neighborhood) level, defined as an area deprivation index score ≥85/100. The primary outcome was hours worked per resident-day among nursing home employees providing direct resident care. Marginal linear regression models and generalized estimating equations with robust sandwich-type standard errors were used to estimate associations between severe neighborhood deprivation and staffing rates. RESULTS: Compared to less deprived neighborhoods, unadjusted staffing rates in facilities located within severely deprived neighborhoods were 38% lower for physical and occupational therapists, 30% lower for registered nurses (RNs), and 5% lower for certified nursing assistants. No disparities in licensed practical nurse (LPN) staffing were observed. In models with state-level and rurality fixed effects and clustered on the county, a similar pattern of disparities was observed. Specifically, RN staffing per 100 resident-days was significantly lower in facilities located within severely deprived neighborhoods as compared to those in less deprived areas (mean difference: 5.6 fewer hours, 95% confidence interval [CI] 4.2-6.9). Disparities of lower magnitude were observed for other clinical disciplines except for LPNs. CONCLUSIONS: Significant staffing disparities were observed within facilities located in severely deprived neighborhoods. Targeted interventions, including workforce recruitment and retention efforts, may be needed to improve staffing levels for nursing homes in deprived neighborhoods.

Architecture of the outbred brown fat proteome defines regulators of metabolic physiology.

Brown adipose tissue (BAT) regulates metabolic physiology. However, nearly all mechanistic studies of BAT protein function occur in a single inbred mouse strain, which has limited the understanding of generalizable mechanisms of BAT regulation over physiology. Here, we perform deep quantitative proteomics of BAT across a cohort of 163 genetically defined diversity outbred mice, a model that parallels the genetic and phenotypic variation found in humans. We leverage this diversity to define the functional architecture of the outbred BAT proteome, comprising 10,479 proteins. We assign co-operative functions to 2,578 proteins, enabling systematic discovery of regulators of BAT. We also identify 638 proteins that correlate with protection from, or sensitivity to, at least one parameter of metabolic disease. We use these findings to uncover SFXN5, LETMD1, and ATP1A2 as modulators of BAT thermogenesis or adiposity, and provide OPABAT as a resource for understanding the conserved mechanisms of BAT regulation over metabolic physiology.

Exploring the Evidence: Symptom Burden in Chronic Kidney Disease.

Chronic kidney disease (CKD) is more prevalent in individuals with obesity, diabetes mellitus, or hypertension. Individuals with CKD are prone to kidney failure, with symptom experiences that rival those of patients with cancer. We explored symptom burden in individuals with CKD via a systematic review of 30 quantitative and qualitative articles. The most common CKD symptoms were fatigue, weakness, pain, sleep disturbances and itchy skin. Instruments used to assess symptoms were the Kidney Disease Quality of Life (KDQOL)-36, the Palliative Outcome Symptom-Scale renal (POS-r)-13, and the Dialysis Symptom Index (DSI)-10. The included qualitative studies expand and expound on the quantitative data presented. This article describes the prevalence of symptom burden in individuals with CKD in relation to psychosocial and demographic factors and discuss the importance of symptom management.

Uptake and Removal of Uranium by and from Human Teeth.

Uranium-238 (238U), a long-lived radiometal, is widespread in the environment because of both naturally occurring processes and anthropogenic processes. The ingestion or inhalation of large amounts of U is a major threat to humans, and its toxicity is considered mostly chemical rather than radiological. Therefore, a way to remove uranium ingested by humans from uranium-contaminated water or from the air is critically needed. This study investigated the uranium uptake by hydroxyapatite (HAP), a compound found in human bone and teeth. The uptake of U by teeth is a result of U transport as dissolved uranyl (UO22+) in contaminated water, and U adsorption has been linked to delays in both tooth eruption and development. In this present work, the influence of pH, contact time, initial U concentration, and buffer solution on the uptake and removal of U in synthetic HAP was investigated and modeled. The influence of pH (pH of human saliva, 6.7-7.4) on the uptake of uranyl was negligible. Furthermore, the kinetics were extremely fast; in one second of exposure, 98% of uranyl was uptaken by HAP. The uptake followed pseudo-second-order kinetics and a Freundlich isotherm model. A 0.2 M sodium carbonate solution removed all the uranyl from HAP after 1 h. Another series of in vitro tests were performed with real teeth as targets. We found that, for a 50 mg/L U in PBS solution adjusted to physiological pH, ∼35% of the uranyl was uptaken by the tooth after 1 h, following pseudo-first-order kinetics. Among several washing solutions tested, a commercially available carbonate, as well as a commercially available fluoride solution, enabled removal of all the uranyl taken up by the teeth.

The Challenges, Joys, and Career Satisfaction of Women Graduates of the Robert Wood Johnson Clinical Scholars Program 1973-2011.

BACKGROUND: To ensure a next generation of female leaders in academia, we need to understand challenges they face and factors that enable fellowship-prepared women to thrive. We surveyed woman graduates of the Robert Wood Johnson Clinical Scholars Program (CSP) from 1976 to 2011 regarding their experiences, insights, and advice to women entering the field. METHODS: We surveyed every CSP woman graduate through 2012 (n = 360) by email and post. The survey, 12 prompts requiring open text responses, explored current work situation, personal definitions of success, job negotiations, career regrets, feelings about work, and advice for others. Four independent reviewers read overlapping subsets of the de-identified data, iteratively created coding categories, and defined and refined emergent themes. RESULTS: Of the 360 cohort, 108 (30%) responded. The mean age of respondents was 45 (range 32 to 65), 85% are partnered, and 87% have children (average number of children 2.15, range 1 to 5). We identified 11 major code categories and conducted a thematic analysis. Factors common to very satisfied respondents include personally meaningful work, schedule flexibility, spousal support, and collaborative team research. Managing professional-personal balance depended on career stage, clinical specialty, and children's age. Unique to women who completed the CSP prior to 1995 were descriptions of "atypical" paths with career transitions motivated by discord between work and personal ambitions and the emphasis on the importance of maintaining relevance and remaining open to opportunities in later life. CONCLUSIONS: Women CSP graduates who stayed in academic medicine are proud to have pursued meaningful work despite challenges and uncertain futures. They thrived by remaining flexible and managing change while remaining true to their values. We likely captured the voices of long-term survivors in academic medicine. Although transferability of these findings is uncertain, these voices add to the national discussion about retaining clinical researchers and keeping women academics productive and engaged.

Genome analysis of three Pneumocystis species reveals adaptation mechanisms to life exclusively in mammalian hosts.

Pneumocystis jirovecii is a major cause of life-threatening pneumonia in immunosuppressed patients including transplant recipients and those with HIV/AIDS, yet surprisingly little is known about the biology of this fungal pathogen. Here we report near complete genome assemblies for three Pneumocystis species that infect humans, rats and mice. Pneumocystis genomes are highly compact relative to other fungi, with substantial reductions of ribosomal RNA genes, transporters, transcription factors and many metabolic pathways, but contain expansions of surface proteins, especially a unique and complex surface glycoprotein superfamily, as well as proteases and RNA processing proteins. Unexpectedly, the key fungal cell wall components chitin and outer chain N-mannans are absent, based on genome content and experimental validation. Our findings suggest that Pneumocystis has developed unique mechanisms of adaptation to life exclusively in mammalian hosts, including dependence on the lungs for gas and nutrients and highly efficient strategies to escape both host innate and acquired immune defenses.
