RESUMEN

PURPOSE: Moral distress (MD) is the result of barriers or constraints that prevent providers from carrying out what they believe to be ethically appropriate care. This study was initiated to explore associations between MD, burnout, and the organizational climate (OC) for oncology physician assistants (PAs). METHODS: A national survey of oncology PAs was conducted to explore the associations between MD, OC, and burnout. The Nurse Practitioner-Primary Care OC Questionnaire was revised for oncology PAs to assess OC for PA practice. MD and burnout were assessed using the Measure of MD-Healthcare Professionals (MMD-HP) and the Maslach Burnout Inventory. RESULTS: One hundred forty-six oncology PAs are included in the analysis. PAs were mostly female (90%), White/Caucasian (84%), married/partnered (78%), and in medical oncology (73%), with mean age 41.0 years. The mean MMD-HP score for oncology PAs was 71.5 and there was no difference in MD scores on the basis of oncology subspecialty, practice setting, practice type, or hours worked per week. PAs currently considering leaving their position because of MD had significantly higher mean scores on the MMD-HP compared with those not considering leaving their position (108.2 v 64.8; P = .001). PAs with burnout also had significantly higher mean scores for MD compared with PAs without burnout (97.6 v 54.3; P < .001). A negative relationship between OC for PA practice and MD was only found for the PA-administration relations subscale, whereas all subscales were negatively associated with burnout. CONCLUSION: This study demonstrates that the risk of professional burnout increases significantly with increasing levels of MD. Additional research exploring the relationship between MD and burnout is needed.

RESUMEN

PURPOSE: Despite an increase in the number of physician assistants (PAs) in the oncology workforce, their potential to meet anticipated demand for oncology services may be hindered by high rates of burnout. The aim of this study was to examine the association between organizational context (OC) and burnout among oncology PAs to better understand factors associated with burnout. METHODS: A national survey of oncology PAs was conducted to explore relationships between burnout and the OC in which the PA practiced. The Areas of Worklife Survey (AWS) assessed OC by examining six key workplace qualities (workload, control, reward, community, fairness, and values). Burnout was assessed using the Maslach Burnout Inventory. RESULTS: PAs demonstrating burnout scored significantly lower across all domains of the AWS than those without burnout (P < .001 for each AWS subscale). The median score for each domain of the AWS and burnout (No v Yes) were as follows: workload (3.33 v 2.67), control (3.67 v 3.00), reward (4.00 v 3.67), community (4.00 v 3.67), fairness (3.33 v 2.67), and values (4.00 v 3.33). Multivariable analysis found that mismatches between the PA and their work environment in workload (odds ratio [OR] = 1.99; 95% CI, 1.32 to 3.02; P = .001), reward (OR = 1.89, 95% CI, 1.18 to 3.02; P = .008), and values (OR = 2.25; 95% CI, 1.31 to 3.88; P = .003) were more likely to report burnout. Differences in burnout in the context of workload were not explained by patient volume, practice structure, or professional autonomy. CONCLUSION: Workload, reward, and values were associated with greater odds of burnout, with workload being the most common mismatch in job fit. Sustainable workloads and consistency in rewards (financial, institutional, and social) for oncology PAs should be an employer's focus to help mitigate their risk of burnout.

RESUMEN

PURPOSE: Burnout has significant implications for the individual provider, the oncology workforce, and the quality of care for patients with cancer. The primary aim of this study was to explore temporal changes in burnout among physician assistants (PAs) in oncology in 2019 compared with 2015. METHODS: Oncology PAs were surveyed to assess for burnout using the Maslach Burnout Inventory according to the same cross-sectional design of the study performed in 2015. Comparison between oncology PAs in 2015 and 2019 in the prevalence of burnout and personal and professional characteristics was performed. RESULTS: Two hundred thirty-four participants completed the full-length survey. The participants in 2015 and 2019 were similar in age (41.8 v 40.3 years), sex (88.8% v 86.3% female), number of years as a PA in oncology (9.6 v 10), and percentage involved in academic practice (55.2% v 59.2%). There was a significant increase in burnout in 2019 compared with 2015 with 48.7% of PAs reporting at least one symptom of burnout compared with 34.8% (odds ratio for burnout, 2019 v 2015 = 1.92 [95% CI, 1.40 to 2.65], P < 0.001). The odds of burnout remained higher in 2019 compared with 2015 when adjusted for age, sex, relationship status, practice setting, subspecialty, practice type, and hours worked. Factors associated with burnout in both 2015 and 2019 include the percentage of time spent on patient care, collaborative physician relationship, number of hours worked, and satisfaction with compensation. No new factors associated with burnout emerged in 2019 that were not identified in 2015. CONCLUSION: The rate of burnout of oncology PAs has significantly increased. Burnout in oncology PAs is multifactorial, and the increase cannot be easily explained. Additional research is needed to better define the drivers of PA burnout.

RESUMEN

The eukaryotic domain-conserved TORC1 signalling pathway connects growth with nutrient sufficiency, promoting anabolic processes such as ribosomal biogenesis and protein synthesis. In Saccharomyces cerevisiae, TORC1 is activated mainly by the nitrogen sources. Recently, this pathway has gotten renewed attention but now in the context of the alcoholic fermentation, due to its key role in nitrogen metabolism regulation. Although the distal and proximal effectors downstream TORC1 are well characterised in yeast, the mechanism by which TORC1 is activated by nitrogen sources is not fully understood. In this work, we took advantage of a previously developed microculture-based methodology, which indirectly evaluates TORC1 activation in a nitrogen upshift experiment, to identify genetic variants affecting the activation of this pathway. We used this method to phenotype a recombinant population derived from two strains (SA and WE) with different geographic origins, which show opposite phenotypes for TORC1 activation by glutamine. Using this phenotypic information, we performed a QTL mapping that allowed us to identify several QTLs for TORC1 activation. Using a reciprocal hemizygous analysis, we validated GUS1, KAE1, PIB2, and UTH1 as genes responsible for the natural variation in the TORC1 activation. We observed that reciprocal hemizygous strains for KAE1 (ATPase required for t6A tRNA modification) gene showed the greatest phenotypic differences for TORC1 activation, with the hemizygous strain carrying the SA allele (KAE1 SA ) showing the higher TORC1 activation. In addition, we evaluated the fermentative capacities of the hemizygous strains under low nitrogen conditions, observing an antagonistic effect for KAE1 SA allele, where the hemizygous strain containing this allele presented the lower fermentation rate. Altogether, these results highlight the importance of the tRNA processing in TORC1 activation and connects this pathway with the yeasts fermentation kinetics under nitrogen-limited conditions.

RESUMEN

Saccharomyces cerevisiae is the main species responsible for the alcoholic fermentation in wine production. One of the main problems in this process is the deficiency of nitrogen sources in the grape must, which can lead to stuck or sluggish fermentations. Currently, yeast nitrogen consumption and metabolism are under active inquiry, with emphasis on the study of the TORC1 signalling pathway, given its central role responding to nitrogen availability and influencing growth and cell metabolism. However, the mechanism by which different nitrogen sources activates TORC1 is not completely understood. Existing methods to evaluate TORC1 activation by nitrogen sources are time-consuming, making difficult the analyses of large numbers of strains. In this work, a new indirect method for monitoring TORC1 pathway was developed on the basis of the luciferase reporter gene controlled by the promoter region of RPL26A gene, a gene known to be expressed upon TORC1 activation. The method was tested in strains representative of the clean lineages described so far in S. cerevisiae. The activation of the TORC1 pathway by a proline-to-glutamine upshift was indirectly evaluated using our system and the traditional direct methods based on immunoblot (Sch9 and Rps6 phosphorylation). Regardless of the different molecular readouts obtained with both methodologies, the general results showed a wide phenotypic variation between the representative strains analysed. Altogether, this easy-to-use assay opens the possibility to study the molecular basis for the differential TORC1 pathway activation, allowing to interrogate a larger number of strains in the context of nitrogen metabolism phenotypic differences.

RESUMEN

Background: Germline genetic testing is standard practice in oncology. Outcomes of telephone disclosure of a wide range of cancer genetic test results, including multigene panel testing (MGPT) are unknown. Methods: Patients undergoing cancer genetic testing were recruited to a multicenter, randomized, noninferiority trial (NCT01736345) comparing telephone disclosure (TD) of genetic test results with usual care, in-person disclosure (IPD) after tiered-binned in-person pretest counseling. Primary noninferiority outcomes included change in knowledge, state anxiety, and general anxiety. Secondary outcomes included cancer-specific distress, depression, uncertainty, satisfaction, and screening and risk-reducing surgery intentions. To declare noninferiority, we calculated the 98.3% one-sided confidence interval of the standardized effect; t tests were used for secondary subgroup analyses. Only noninferiority tests were one-sided, others were two-sided. Results: A total of 1178 patients enrolled in the study. Two hundred eight (17.7%) participants declined random assignment due to a preference for in-person disclosure; 473 participants were randomly assigned to TD and 497 to IPD; 291 (30.0%) had MGPT. TD was noninferior to IPD for general and state anxiety and all secondary outcomes immediately postdisclosure. TD did not meet the noninferiority threshold for knowledge in the primary analysis, but it did meet the threshold in the multiple imputation analysis. In secondary analyses, there were no statistically significant differences between arms in screening and risk-reducing surgery intentions, and no statistically significant differences in outcomes by arm among those who had MGPT. In subgroup analyses, patients with a positive result had statistically significantly greater decreases in general anxiety with telephone disclosure (TD -0.37 vs IPD +0.87, P = .02). Conclusions: Even in the era of multigene panel testing, these data suggest that telephone disclosure of cancer genetic test results is as an alternative to in-person disclosure for interested patients after in-person pretest counseling with a genetic counselor.

RESUMEN

BACKGROUND: Inflammation is suggested to be a central feature of atherosclerosis, particularly among smokers. We studied whether inflammatory biomarkers GlycA and high-sensitivity C-reactive protein are associated with cigarette smoking. METHODS AND RESULTS: A total of 11 509 participants, 6774 from the MESA (Multi-Ethnic Study of Atherosclerosis) and 4735 from ELSA-Brasil (The Brazilian Longitudinal Study of Adult Health) were included. We evaluated the cross-sectional association between multiple measures of smoking behavior and the inflammatory biomarkers, GlycA and high-sensitivity C-reactive protein, using regression models adjusted for demographic, anthropometric, and clinical characteristics. Participants were 57.7±11.1 years old and 46.4% were men. Never, former, and current smokers comprised 51.7%, 34.0%, and 14.3% of the population, respectively. Multivariable-adjusted mean absolute difference in GlycA levels (µmol/L) with 95% confidence interval (CI) were higher for former (4.1, 95% CI, 1.7-6.6 µmol/L) and current smokers (19.9, 95% CI, 16.6-23.2 µmol/L), compared with never smokers. Each 5-unit increase in pack-years of smoking was associated with higher GlycA levels among former (0.7, 95% CI, 0.3-1.1 µmol/L) and current smokers (1.6, 95% CI, 0.8-2.4 µmol/L). Among former smokers, each 5-year increase in time since quitting smoking was associated with lower GlycA levels (-1.6, 95% CI, -2.4 to -0.8 µmol/L) and each 10-unit increase in number of cigarettes/day was associated with higher GlycA among current smokers (2.8, 95% CI, 0.5-5.2 µmol/L). There were similar significant associations between all measures of smoking behavior, and both log-transformed GlycA and high-sensitivity C-reactive protein. CONCLUSIONS: Acute and chronic exposure to tobacco smoking is associated with inflammation, as quantified by both GlycA and high-sensitivity C-reactive protein. These biomarkers may have utility for the study and regulation of novel and traditional tobacco products.

RESUMEN

PURPOSE: Multiple-gene, next-generation sequencing panels are increasingly used to assess hereditary cancer risks of patients with diverse personal and family cancer histories. The magnitude of breast and ovarian cancer risk associated with many clinically tested genes, and independent of family cancer history, remains to be quantified. METHODS: We queried a commercial laboratory database of 95,561 women tested clinically for hereditary cancer risk with a 25-gene (APC, ATM, BARD1, BMPR1A, BRCA1, BRCA2, BRIP1, CDH1, CDK4, CHEK2, MLH2, MSH2, MSH6, MUTYH, NBN, P14ARF, P16, PALB2, PMS2, PTEN, RAD51C, RAD51D, SMAD4, STK11, and TP53) next-generation sequencing panel. Multivariable logistic regression models accounting for family history were used to examine the association between pathogenic mutations and breast or ovarian cancer. As a confirmatory approach, a matched case-control analysis was conducted, defining cases as patients with breast or ovarian cancer and controls as women without cancer. RESULTS: One or more pathogenic mutations were detected in 6,775 (7%) of 95,561 women. Eight genes (ATM, BARD1, BRCA1, BRCA2, CHEK2, PALB2, PTEN, and TP53) were associated with breast cancer, with odds ratios (ORs) ranging from two-fold (ATM: OR, 1.74; 95% CI, 1.46 to 2.07) to six-fold (BRCA1: OR, 5.91; 95% CI, 5.25 to 6.67). Eleven genes (ATM, BRCA1, BRCA2, BRIP1, MLH1, MSH2, MSH6, NBN, STK11, RAD51C, and RAD51D) were associated with ovarian cancer, with OR ranging from two-fold (ATM: OR, 1.69; 95% CI, 1.19 to 2.40) to 40-fold (STK11: OR, 41.9; 95% CI, 5.55 to 315). Multivariable models and matched case-control analyses yielded similar results. CONCLUSION: Among nearly 100,000 clinically tested women, 7% carried a pathogenic mutation in one or more cancer-associated genes. Associated breast and ovarian cancer risks ranged from two- to 40-fold after controlling for family history. These results may inform cancer risk counseling.

RESUMEN

PURPOSE: Recent studies have demonstrated increasing rates of financial toxicities and emotional distress related to cancer treatment. This study assessed and characterized the relationships among financial distress, emotional symptoms, and overall distress in patients with cancer. METHODS: A cross-sectional sample of patients with cancer who visited our outpatient medical oncology and psychiatry clinics completed a pen-and-paper survey. The survey assessed demographics; cost concerns; and financial, emotional, and overall distress. RESULTS: One hundred twenty insured patients completed the survey. Sixty-five percent reported clinically significant overall distress scores, with the same percentage reporting at least one emotional problem (worry, anxiety, depression, etc). Twenty-nine percent scored in the range of high to overwhelming financial distress. By using structural equation modeling, we found that financial distress was associated with overall distress. This association was both direct (accounting for 76% of the effect) and indirect (accounting for 24% of the effect) via mediation by emotional distress. CONCLUSION: This cohort of patients with cancer reported significant levels of emotional distress, financial distress, and overall distress. These factors were interrelated, with both financial and emotional distress contributing to overall distress. Interventions targeted at alleviating financial distress may help to decrease levels of overall distress.

RESUMEN

We used a photoactive general anesthetic called meta-azi-propofol (AziPm) to test the selectivity and specificity of alkylphenol anesthetic binding in mammalian brain. Photolabeling of rat brain sections with [(3)H]AziPm revealed widespread but heterogeneous ligand distribution, with [(3)H]AziPm preferentially binding to synapse-dense areas compared to areas composed largely of cell bodies or myelin. With [(3)H]AziPm and propofol, we determined that alkylphenol general anesthetics bind selectively and specifically to multiple synaptic protein targets. In contrast, the alkylphenol anesthetics do not bind to specific sites on abundant phospholipids or cholesterol, although [(3)H]AziPm shows selectivity for photolabeling phosphatidylethanolamines. Together, our experiments suggest that alkylphenol anesthetic substrates are widespread in number and distribution, similar to those of volatile general anesthetics, and that multi-target mechanisms likely underlie their pharmacology.

RESUMEN

Diagnostic imaging is a cornerstone of patient evaluation in the acute care setting, but little effort has been devoted to understanding the appropriate influence of sex and gender on imaging choices. This article provides background on this issue and a description of the working group and consensus findings reached during the diagnostic imaging breakout session at the 2014 Academic Emergency Medicine consensus conference "Gender-specific Research in Emergency Care: Investigate, Understand, and Translate How Gender Affects Patient Outcomes." Our goal was to determine research priorities for how sex and gender may (or should) affect imaging choices in the acute care setting. Prior to the conference, the working group identified five areas for discussion regarding the research agenda in sex- and gender-based imaging using literature review and expert consensus. The nominal group technique was used to identify areas for discussion for common presenting complaints to the emergency department where ionizing radiation is often used for diagnosis: suspected pulmonary embolism, suspected kidney stone, lower abdominal pain with a concern for appendicitis, and chest pain concerning for coronary artery disease. The role of sex- and gender-based shared decision-making in diagnostic imaging decisions is also raised.
