RESUMO

We demonstrate subrecoil Sisyphus cooling using the long-lived ^{3}P_{0} clock state in alkaline-earth-like ytterbium. A 1388-nm optical standing wave nearly resonant with the ^{3}P_{0}→^{3}D_{1} transition creates a spatially periodic light shift of the ^{3}P_{0} clock state. Following excitation on the ultranarrow clock transition, we observe Sisyphus cooling in this potential, as the light shift is correlated with excitation to ^{3}D_{1} and subsequent spontaneous decay to the ^{1}S_{0} ground state. We observe that cooling enhances the loading efficiency of atoms into a 759-nm magic-wavelength one-dimensional (1D) optical lattice, as compared to standard Doppler cooling on the ^{1}S_{0}→^{3}P_{1} transition. Sisyphus cooling yields temperatures below 200 nK in the weakly confined, transverse dimensions of the 1D optical lattice. These lower temperatures improve optical lattice clocks by facilitating the use of shallow lattices with reduced light shifts while retaining large atom numbers to reduce the quantum projection noise. This Sisyphus cooling can be pulsed or continuous and is applicable to a range of quantum metrology applications.

RESUMO

AIM: To assess the protocol feasibility and intervention acceptability of a community-based, peer support diabetes prevention programme (DPP) for African-American (AA) grandmother caregivers at risk for diabetes. MATERIALS AND METHODS: Grandmother caregivers were randomized in a 2:1 ratio to DPP (active comparator) or DPP plus HOPE (Healthy Outcomes through Peer Educators; intervention). DPP + HOPE incorporated support from a peer educator who met with participants in person or by telephone every week during the 1-year intervention. Outcomes included: (1) recruitment rates, outcome assessment, and participation adherence rates assessed quantitatively; and (2) acceptability of the programme assessed through end-of-programme focus groups. RESULTS: We successfully consented and enrolled 78% (n = 35) of the 45 AA grandmothers screened for eligibility. Eighty percent of participants (aged 64.4 ± 5.7 years) were retained up to Week 48 (74% for DPP [n = 17] and 92% for DPP + HOPE [n = 11]). All grandmothers identified social support, neighbourhood safety, and access to grocery stores as influences on their health behaviours. At Month 12, the active comparator (DPP) group and the intervention group (DPP + HOPE) had a mean change in body weight from baseline of -3.5 ± 5.5 (-0.68, -6.29) kg and - 4.4 ± 5.7 (-0.59, -8.2) kg, respectively. CONCLUSIONS: This viable study met the aim of educating and equipping AA grandmothers with the practical and sustained support needed to work toward better health for themselves and their grandchildren, who may be at risk for diabetes. The intervention was both feasible and acceptable to participating grandmothers and their organizations.

RESUMO

PURPOSE: Foundational research demonstrates that spirituality may affect the way people with cancer experience pain. One potential route is through alterations in thoughts and beliefs, such as pain-related catastrophizing. The purpose of this study is to understand whether spirituality impacts pain experiences through pain-related catastrophizing. METHODS: This explanatory sequential mixed methods study was informed by an adapted Theory of Unpleasant Symptoms. Data were collected via online surveys (N = 79) and follow-up qualitative interviews (N = 25). Phase 1 employed Empirical Bayesian analysis. Phase 2 used deductive content analysis. Phase 3 involved creating a mixed methods joint display to integrate findings and draw meta inferences. RESULTS: Results indicate that total spiritual well-being was directly negatively associated with pain-related catastrophizing, and indirectly negatively associated with the outcomes of pain interference, pain severity, and pain-related distress. Qualitative categories highlight the supportive role of spirituality when facing pain, while also shedding light on the limitations of spirituality in the context of some pain (i.e., severe, neuropathic, and/or chronic). Mixed methods findings reveal the importance of spirituality for some people as they face cancer and cancer-related pain, as well as the need for integrating spirituality as part of a larger pain management plan. CONCLUSIONS: This research advances supportive cancer care by exploring the complex role of spirituality in pain experiences. Findings will inform further exploration into the role of spirituality in supporting holistic symptom management in the context of cancer, as well as developing and testing interventions to enhance spirituality and address symptom-related suffering.

RESUMO

PURPOSE: To assess the matching and content validity of a pain quality pictogram tool with a Hmong community. DESIGN: A Qualtrics survey was administered to two groups of participants. METHODS: Sixty Hmong participants (n = 49 limited English proficiency and bilingual Hmong community members in group 1; n = 11 bilingual Hmong healthcare practitioners in group 2) participated in this study. Hmong community members in group 1 were asked to identify the pain pictogram that best matched a pre-recorded Hmong pain quality phrase. The practitioners in group 2 were asked to evaluate how well each pain pictogram represented the pre-recorded Hmong pain quality phrase it intended to measure. To assess the matching, we assessed agreement between the pain concept in the phrase and the pictogram intended to represent it, using group 1. A content validity index (CVI) was calculated to assess the content validity of the tool using group 2. RESULTS: Among the community participants, 8 of the 15 pictograms were matched with the intended phrase almost perfectly, and 3 were matched by a substantial majority. There were no differences in matching by patient gender and language proficiency. Among practitioners, 11 of 15 pain pictograms met the CVI threshold of 0.70 for all three dimensions (i.e., representativeness, relevance, and comprehension). CONCLUSION: Findings support including most of the pain pictograms in the tool but suggest specific areas for improvement. CLINICAL IMPLICATIONS: Findings provide insights for redesigning the selected pain pictogram tool to be used in clinical settings with LEP Hmong patients.

RESUMO

This pilot study assessed the feasibility of implementing a pain assessment information visualization (InfoViz) tool to address cultural and language barriers among limited English proficiency (LEP) Hmong patients in primary care. We used a static group comparison design to collect data from 20 patient, interpreter, and provider triads under usual care (i.e., interpreter using verbal pain descriptions), followed by another 20 triads under the intervention (i.e., interpreter using verbal pain descriptions and the InfoViz tool). Feasibility outcomes included recruitment and retention rates, InfoViz tool completion, acceptability, and fidelity. We also assessed mutual understanding (MU) and pain electronic health record (EHR) documentation. Descriptive data were calculated and thematic analysis was conducted. Thirty-six LEP Hmong patients (n = 29 female, mean age = 59.03), 27 providers (n = 15 female), and four interpreters participated in this study. The patient recruitment rate was 18% while the retention rate was 81%. Interpreter recruitment rate was 80%, and 75% for retention rate. The intervention fidelity mean score was 83%. In the intervention condition, patient-provider MU of pain severity improved by 30%, coupled with a 28% increase in pain severity EHR documentation compared to usual care. While communication of pain quality did not improve, there was a higher mean number of pain descriptors (3.31 in the intervention vs. 1.79 in usual care) in EHR documentation. All participants had a positive experience with the tool, reporting it as valuable with 100% completeness of all tools. Findings revealed the tool was acceptable and feasible to use among LEP patients-interpreters-providers, providing support for an efficacy study.

RESUMO

BACKGROUND: System contributors to resident burnout and well-being have been under-studied. We sought to determine factors associated with resident burnout and identify at risk groups. METHODS: We performed a US national survey between July 15 2022 and April 21, 2023 of residents in 36 specialties in 14 institutions, using the validated Mini ReZ survey with three 5 item subscales: 1) supportive workplace, 2) work pace/electronic medical record (EMR) stress, and 3) residency-specific factors (sleep, peer support, recognition by program, interruptions and staff relationships). Multilevel regressions and thematic analysis of 497 comments determined factors related to burnout. RESULTS: Of 1118 respondents (approximate median response rate 32%), 48% were female, 57% White, 21% Asian, 6% LatinX and 4% Black, with 25% PGY 1 s, 25% PGY 2 s, and 22% PGY 3 s. Programs included internal medicine (15.1%) and family medicine (11.3%) among 36 specialties. Burnout (found in 42%) was higher in females (51% vs 30% in males, p = 0.001) and PGY 2's (48% vs 35% in PGY-1 s, p = 0.029). Challenges included chaotic environments (41%) and sleep impairment (32%); favorable aspects included teamwork (94%), peer support (93%), staff support (87%) and program recognition (68%). Worklife subscales were consistently lower in females while PGY-2's reported the least supportive work environments. Worklife challenges relating to burnout included sleep impairment (adjusted Odds Ratio (aOR) 2.82 (95% CIs 1.94, 4.19), absolute risk difference (ARD) in burnout 15.9%), poor work control (aOR 2.25 (1.42, 3.58), ARD 12.2%) and chaos (aOR 1.73 (1.22, 2.47), ARD 7.9%); program recognition was related to lower burnout (aOR 0.520 (0.356, 0.760), ARD 9.3%). These variables explained 55% of burnout variance. Qualitative data confirmed sleep impairment, lack of schedule control, excess EMR and patient volume as stressors. CONCLUSIONS: These data provide a nomenclature and systematic method for addressing well-being during residency. Work conditions for females and PGY 2's may merit attention first.

RESUMO

PURPOSE: To evaluate the implementation of MOVIN, a multicomponent mobility intervention, by a nurse-led team and measure the effectiveness on unit-level outcomes. METHOD: A pragmatic quasi-experimental study was conducted on an inpatient adult medical unit. Evaluation was guided by the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. Interviews with 13 organizational partners were conducted to understand barriers and facilitators to adoption. Thematic analysis was used to analyze the data. Quantitative data to determine effectiveness on distance of patient ambulation and percent of patients ambulated by nursing staff were analyzed using an interrupted time series. RESULTS: A significant increase in total weekly distances for patient ambulation and percent of patients ambulated by nursing staff occurred between preintervention, intervention, and postintervention periods. Themes for adoption included: Value, Immediate Feedback, Inclusive Implementation, Resource Needs, and Lack of Organizational Evidence. The nurse-led team demonstrated high fidelity to maintaining the core components of MOVIN. CONCLUSION: A nurse-led team can successfully launch a multicomponent mobility intervention and sustain impact. RE-AIM supported assessments of key partners at multiple organizational levels, capturing critical unit level outcomes. Multiple methods for data collection and analysis yielded rich results to inform future dissemination of MOVIN. [Research in Gerontological Nursing, 17(4), 189-201.].

RESUMO

Background: The presence of poorly controlled symptoms negatively impacts the quality of life (QoL) throughout cancer treatment. The purpose of this multisite study was to explore the relationship between QoL and symptom adverse events (AEs) in children with advanced cancer over 6 months. Method: A prospective and longitudinal descriptive study design was used to collect QoL and symptom AE data from children aged 2 to 18 with advanced cancer. QoL was measured using the Pediatric Quality of Life Inventory (PedsQLTM) Cancer Module 3.0 and symptom AEs were measured using the Pediatric Patient-Reported Outcome-Common Terminology Criteria for AEs (PRO-CTCAEs®). Descriptive statistics were used to describe QoL and symptom AE data. Correlational analyses and generalized linear mixed models were used to examine the relationship between symptom AEs and QoL. Results: Forty-nine children participated in the study. The mean total PedsQLTM score was 73.86 for the sample across all time points. Children diagnosed with a central nervous system (CNS) tumor reported poorer QoL compared to children diagnosed with a hematologic malignancy or non-CNS solid tumor. Symptom frequency AEs of anxiety, pain, nausea, insomnia, hot flashes, and fatigue severity demonstrated the strongest and most significant negative correlation with total QoL scores. Analyses of the relationship between QoL and symptom AEs over time revealed time-specific significant differences with children who experienced frequency AEs of nausea, and anxiety reporting poorer QoL at time point 4 (week 8). Discussion: The Ped PRO-CTCAE® and PedsQLTM can be used to evaluate the relationship between symptom AEs and QoL in practice and in future research.

RESUMO

PURPOSE: The study's aims were (a) to evaluate hearing status and (b) word recognition ability of Hmong speakers using four validated monosyllabic word recognition tests in the White Hmong dialect and (c) to assess the relationship between the participant's language and the average word recognition percent correct scores, adjusting for age, gender, and degree of hearing loss. METHOD: Participants listened to two randomly assigned validated Hmong word lists (male/female talker) for each ear. Pure-tone air- and bone-conduction thresholds as well as word recognition ability were measured. Descriptive statistics were calculated to analyze the percent correct of word lists and classify hearing status. A nonparametric regression analysis was used to assess the relationship between the participant's language and the average word recognition percent correct scores, adjusting for age, gender, and degree of hearing loss. RESULTS: Forty-eight Hmong (25 females, 23 males; Mage = 44.4) participated in this study. Thirty-three participants had hearing loss in at least one ear, and 15 had hearing within normal limits bilaterally. Participants with normal, mild, or steeply sloping hearing loss reached an average word recognition score of > 94% on Hmong lists by both male and female talkers. Participants with moderate-to-severe hearing loss scored 68% on average for the male talker Hmong lists and 60% on average for the female talker Hmong lists. Gender was significantly positively associated with average word recognition percent correct on the female word lists (b = -0.224, p = .047) but not statistically significant for the male word lists (b = 7.579, p = .141). CONCLUSION: Findings provide support for the use of the four Hmong word lists in clinical settings.

RESUMO

Objective: Assess implementation feasibility and outcomes for an Osteoarthritis Management Program (OAMP) at an academic center. Design: This open study assessed an OAMP designed to deliver care in 1-5 individual or group visits across ≤12 months. Eligibility included adults with knee or hip osteoarthritis with ≥1 visit from 7/1/2017-1/15/2021. A multidisciplinary care team provided: education on osteoarthritis, self-management, exercise, weight loss; pharmacologic management; assessments of mood, sleep, quality of life, and diet. Clinic utilization and growth are reported through 2022. Patient outcomes of body mass index (BMI), pain, and function were analyzed using multivariable general linear models. OAMP outcomes were feasibility and sustainability. Results: Most patients were locally referred by primary care. 953 patients attended 2531 visits (average visits 2.16, treatment duration 187.9 days). Most were female (72.6%), older (62.1), white (91.1%), and had medical insurance (95.4%). Obesity was prevalent (84.7% BMI ≥30, average BMI 40.9), mean Charlson Comorbidity Index was 1.89, and functional testing was below average. Longitudinal modeling revealed statistically but not clinically significant pain reduction (4.4-3.9 on 0-10 scale, p â€‹= â€‹0.002). BMI did not significantly change (p â€‹= â€‹0.87). Higher baseline pain and BMI correlated with greater reductions in each posttreatment. Uninsured patients had shorter treatment duration. Increasing clinic hours (4-24 â€‹h weekly) and serving 953 patients over four years demonstrated OAMP sustainability. Conclusions: OAMP implementation was feasible and sustainable. Patients with high baseline pain and BMI were more likely to improve. Noninsurance was a barrier. These results contribute to understanding OAMP outcomes in U.S. healthcare.

RESUMO

Background: Few studies have examined biomarkers of stress and inflammation as underlying mechanisms of symptoms in adolescents and young adults with cancer. This study determined the feasibility of collecting blood and saliva samples across time, described the range and distribution of biomarkers, and explored the association of biomarkers with symptom adverse events (AEs). Method: This longitudinal, prospective repeated-measures single-site feasibility study recruited N = 10 children (M = 12.5 years) receiving treatment for advanced cancer. Symptom AE data and inflammation (cytokines and C-reactive protein) and physiologic response to stress (salivary cortisol and salivary alpha-amylase) biomarker levels were collected at three time points. Descriptive statistics were used to examine feasibility and acceptability and to summarize symptom AE, stress, and inflammatory biomarker data. A linear regression model was used to determine cortisol diurnal slopes. The relationship between symptom and inflammatory biomarker data was explored and Hedges's g statistic was used to determine its effect size. Results: Participants provided 83% of saliva samples (n = 199/240) and 185 samples were sufficient to be analyzed. Nurses collected 97% (n = 29/30) of blood samples. Participants reported the saliva collection instructions, kits, and reminders were clear and helpful. Insomnia, pain, fatigue, and anxiety demonstrated the most medium and large negative effects with inflammatory markers. Symptom AEs demonstrated the highest number of medium and large negative effects with interleukin-8 and tumor necrosis factor-alpha (-0.53 to -2.00). Discussion: The results indicate longitudinal concurrent collection of symptom and biomarker data is feasible and inflammatory and stress biomarkers merit consideration for inclusion in future studies.

RESUMO

AIM: Feeling valued is a striking mitigator of burnout yet how to facilitate healthcare workers (HCWs) feeling valued has not been adequately studied. This study discovered factors relating to HCWs feeling valued so leaders can mitigate burnout and retain their workforce. METHOD: The Coping with COVID-19 survey, initiated in March 2020 by the American Medical Association, was distributed to 208 US healthcare organisations. Of the respondents, 37 685 physicians, advanced practice clinicians, nurses, and other clinical staff answered questions that assessed burnout, intent to leave and whether they felt valued.Quantitative analysis looked at odds of burnout and intent to leave among the highest versus lowest feeling valued (FV) groups. Open-ended comments provided by 5559 respondents with high or low sense of FV were analysed to understand aspects of work life that contributed to FV. RESULTS: Of 37 685 respondents, 45% felt valued; HCWs who felt highly valued had 8.3 times lower odds of burnout and 10.2 lower odds of intent to leave than those who did not feel valued at all. Qualitative data identified six themes associated with FV: (1) physical safety, (2) compensation and pandemic-related finances, (3) transparent and frequent communication, (4) effective teamwork, (5) empathetic and respectful leaders, and (6) organisational support. CONCLUSION: This US study demonstrates that FV correlates with burnout and intent to leave, yet only 45% of HCWs feel valued. Six themes link to interventions leaders can follow to facilitate HCWs FV and potentially reduce burnout and increase retention for a challenged healthcare workforce.

RESUMO

BACKGROUND: Maternal history of trauma is a risk factor for distress during pregnancy. The purpose of this paper was to examine the theorized differential impact of a cognitive behavioral intervention (Mothers and Babies Personalized; MB-P) on maternal distress and emotional regulation for those with ≥ 1 adverse childhood experiences (ACEs; vs no ACEs) from pregnancy to 3 months postpartum. METHODS: Between August 2019 and August 2021, eligible pregnant individuals aged ≥ 18 years, < 22 weeks' gestation, and English-speaking were recruited from 6 university-affiliated prenatal clinics. Participants (N = 100) were randomized to MB-P (n = 49) or control (n = 51). Analyzable data were collected for 95 participants. Analyses tested progression of change (slope) and at individual timepoints (panel analysis) for perinatal mental health outcomes. RESULTS: The majority of participants (n = 68, 71%) reported experiencing > 1 ACE (median = 1, range: 0-11). Participants demonstrated significant differential effects for depressive symptoms in absence of ACEs (standardized mean differences [SMD] = 0.82; 95% confidence interval [CI] = [0.13-1.51]) vs in presence of ACEs (SMD = 0.39; 95% CI = [-0.20 to 0.97]) and perceived stress in absence of ACEs (SMD = 0.92; 95% CI = [0.23-1.62]) vs in presence of ACEs (SMD = -0.05; 95% CI = [-0.63 to 0.53]). A panel analysis showed significantly reduced depressive symptoms postintervention and increased negative mood regulation at 3 months postpartum for individuals with ACEs. CONCLUSIONS: Findings support effectiveness of the MB-P intervention to reduce prenatal distress for all pregnant individuals. Preliminary exploration suggests the possibility that individuals with ACEs may benefit from enhanced trauma-informed content to optimize the effects of a perinatal intervention.
