RESUMEN

Healthcare personnel experienced unprecedented stressors and risk factors for burnout, anxiety, and depression during the COVID-19 pandemic. This may have been particularly true for spiritual health clinicians (SHCs), also referred to as healthcare chaplains. We administered a daily pulse survey that allowed SHCs to self-report burnout, depression, and well-being, administered every weekday for the first year of the pandemic. We used a series of linear regression models to evaluate whether burnout, depression, and well-being were associated with local COVID-19 rates in the chaplains' hospital system (COVID-19 admissions, hospital deaths from COVID-19, and COVID-19 ICU census). We also compared SHC weekly rates with national averages acquired by the U.S. Census Bureau's Household Pulse Survey (HPS) data during the same timeframe. Of the 840 daily entries from 32 SHCs, 90.0% indicated no symptoms of burnout and 97.1% were below the cutoff for depression. There was no statistically significant relationship between any of the COVID-19 predictors and burnout, depression, or well-being. Mean national PHQ-2 scores were consistently higher than our sample's biweekly means. Understanding why SHCs were largely protected against burnout and depression may help in addressing the epidemic of burnout among healthcare providers and for preparedness for future healthcare crises.

RESUMEN

Healthcare chaplains address broad social and emotional dimensions of care within a pluralistic religious landscape. Although the development and evaluation of chaplaincy interventions has advanced the field, little research has investigated factors influencing the implementation of new chaplain interventions. In this mixed-method study, we examined attitudes about evidence-based interventions held by chaplain residents (n = 39) at the outset of an ACPE-accredited residency program in the southeast United States. We also used semi-structured interviews (n = 9) to examine residents' attitudes, beliefs, and decision-making processes after they trained in the delivery of a novel manualized intervention, Compassion-Centered Spiritual Health (CCSH). Most residents reported favorable attitudes toward manualized approaches prior to training. Interviews revealed complex decision-making processes and highlighted personal motivations and challenges to learning and implementing CCSH. Implementation science can reveal factors related to motivation, intention, and training that may be optimized to improve the implementation of healthcare chaplaincy interventions.

RESUMEN

BACKGROUND: Psychedelic-assisted therapies hold early promise for treating multiple psychiatric conditions. However, absent standards for the care, teams providing psychedelic-assisted therapy pose a major roadblock to safe administration. Psychedelics often produce spiritually and existentially meaningful experiences, and spiritual health practitioners have been involved in administering psychedelic-assisted therapies in multiple settings, suggesting important qualifications for delivering these therapies. However, the roles and competencies of spiritual health practitioners in psychedelic-assisted therapies have not been described in research. METHOD: This study examined interviews with 15 spiritual health practitioners who have facilitated psychedelic-assisted therapy. Thematic analyses focused on their contributions, application of expertise and professional background, and roles in administering these therapies. RESULTS: Seven themes emerged, comprising two domains: unique and general contributions. Unique contributions included: competency to work with spiritual material, awareness of power dynamics, familiarity with non-ordinary states of consciousness, holding space, and offer a counterbalance to biomedical perspectives. General contributions included use of generalizable therapeutic repertoire when conducting PAT, and contributing to interdisciplinary collaboration. IMPLICATIONS: Spiritual health practitioners bring unique and specific expertise to psychedelic-assisted therapy based on their training and professional experience. They are skilled at interprofessional collaboration in a way that complements other clinical team members. Psychedelic-assisted therapy teams may benefit from including spiritual health practitioners. In order to ensure rigorous standards and quality care, further efforts to delineate the roles and necessary qualifications and training of spiritual health clinicians for psychedelic-assisted therapy are needed.

RESUMEN

Bereavement increases in prevalence as people age and is associated with multiple psychological and health risks, including cardiovascular risk. Religious and existential variables may play an important role in the health impacts of bereavement. Theorized pathways linking religious and existential variables with health have suggested these associations are due to intermediary psychosocial variables, but have not been tested in bereavement. This research empirically tested these pathways in a bereaved population. In N = 73 adults within 1 year of bereavement (mean age = 64.36), this study examined associations between (1) religious and existential characteristics (religious and spiritual struggles, intrinsic religiosity, and existential quest) and intermediary psychosocial variables (depression, loneliness, and difficulties in emotion regulation), and between (2) intermediary psychosocial variables and bereavement-relevant health outcomes (self-reported health, change in health since last year, grief severity, and cardiovascular biomarkers). Cardiovascular biomarkers (heart rate, heart rate variability, and blood pressure) were collected before, during, and after a laboratory grief recall emotion elicitation. Anticipated associations between self-reported religious and existential characteristics and intermediary variables, and between intermediary variables and self-reported bereavement-relevant outcomes, were consistently observed. However, associations between intermediary variables and cardiovascular biomarkers were largely unobserved. This study examined the role of religious and existential variables in whole-person health after bereavement and is among the first to include biomarkers of cardiovascular risk. Results suggest that although religious and existential variables are associated with important bereavement-related outcomes, these associations may be "skin-deep," and extensions to cardiovascular functioning should be re-examined.

RESUMEN

Importance: Mounting evidence supports the role of spiritual, existential, religious, and theological components in mediating psychedelic-assisted therapy, yet integration of these elements into the clinical setting is lagging. Observations: Although psychedelic-assisted therapy commonly produces spiritually, existentially, religiously, or theologically relevant experiences for patients, these have not been systematically integrated into the psychotherapies that accompany therapeutic uses of psychedelics. As a key feature and potential mediator of therapeutic effects, evidence-based psychedelic-assisted therapies should include these topics in the treatment model. Research across multiple diagnostic targets and treatment contexts suggests that spiritually integrated psychotherapies are effective, feasible, and produce add-on benefits in spiritually, existentially, religiously, and theologically relevant outcomes, which are particularly germane to psychedelics. Established standards in spiritually integrated psychotherapy may be fruitfully applied to psychedelic-assisted therapy. Objectives for spiritually, existentially, religiously, and theologically integrated psychedelic-assisted therapy based on these standards and informed by considerations specific to psychedelics are recommended. Conclusions and Relevance: Spiritual, existential, religious, and theological topics' integration in psychedelic-assisted therapy is needed to ensure culturally competent, evidence-based treatment aligned with the highest standards of clinical care. Neglecting to address these topics can detract from cultural competence, contribute to risks for patients, and potentially undermine treatment success.

RESUMEN

Objectives: Although hospital chaplains play a critical role in delivering emotional and spiritual care to a broad range of both religious and non-religious patients, there is remarkably little research on the best practices or "active ingredients" of chaplain spiritual consults. Here, we examined how chaplains' compassion capacity was associated with their linguistic behavior with hospitalized inpatients, and how their language in turn related to patient outcomes. Methods: Hospital chaplains (n = 16) completed self-report measures that together were operationalized as self-reported "compassion capacity." Next, chaplains conducted consultations with inpatients (n = 101) in five hospitals. Consultations were audio-recorded, transcribed, and analyzed using Linguistic Inquiry Word Count (LIWC). We used exploratory structural equation modeling to identify associations between chaplain-reported compassion capacity, chaplain linguistic behavior, and patient depression after the consultation. Results: We found that compassion capacity was significantly associated with chaplains' LIWC clout scores, a variable that reflects a confident leadership, inclusive, and other-oriented linguistic style. Clout scores, in turn, were negatively associated with patient depression levels controlling for pre-consult distress, indicating that patients seen by chaplains displaying high levels of clout had lower levels of depression after the consultation. Compassion capacity exerted a statistically significant indirect effect on patient depression via increased clout language. Conclusions: These findings inform our understanding of the linguistic patterns underlying compassionate and effective chaplain-patient consultations and contribute to a deeper understanding of the skillful means by which compassion may be manifest to reduce suffering and enhance well-being in individuals at their most vulnerable.

RESUMEN

Over the last decade, numerous interventions and techniques that aim to engender, strengthen, and expand compassion have been created, proliferating an evidence base for the benefits of compassion meditation training. However, to date, little research has been conducted to examine individual variation in the learning, beliefs, practices, and subjective experiences of compassion meditation. This mixed-method study examines changes in novice meditators' knowledge and contemplative experiences before, during, and after taking an intensive course in CBCT® (Cognitively-Based Compassion Training), a contemplative intervention that is increasingly used for both inter- and intrapersonal flourishing. The participants in this study (n = 40) were Christian healthcare chaplains completing a 1-year residency in Clinical Pastoral Education (CPE) who learned CBCT as part of their professional chaplaincy training curriculum. Prior to and upon completion of training, we surveyed participants to assess their beliefs about the malleability of compassion, types of engagement in compassion meditation, and perceptions of the impact of taking CBCT. We also conducted in-depth interviews with a subset of participants to gain a qualitative understanding of their subjective experiences of learning and practicing compassion meditation, a key component of CBCT. We found that participants reported increases in the extent to which they believed compassion to be malleable after studying CBCT. We also found high levels of variability of individual ways of practicing and considered the implications of this for the study of contemplative learning processes. This multi-methodological approach yielded novel insights into how compassion practice and compassion-related outcomes interrelate, insights that can inform the basic scientific understanding of the experience of learning and enacting compassion meditation as a means of strengthening compassion itself.

RESUMEN

While oncology clinical research coordinators (CRCs) experience a combination of factors that are thought to put them at increased risk for burnout, very little research has been conducted to understand the risk factors associated with burnout among CRCs. We used a mixed-method approach, including self-report questionnaires to assess burnout and compassion satisfaction, as well as individual and interpersonal variables hypothesized to impact CRC well-being. We also conducted a focus group to gain a more nuanced understanding of coordinators' experiences around burnout, teamwork, resilience, and incivility. Coordinators reported relatively moderate levels of burnout and compassion satisfaction. Resilience, sleep dysfunction, stress, and incivility experienced from patients/family were significant predictors of burnout. Resilience and incivility from patients/family were significant predictors of compassion satisfaction. Themes that emerged from the focus group included that burnout is triggered by feeling overwhelmed from the workload, which is buffered by what was described as a supportive work culture based in teamwork. This study identified variables at the individual and interpersonal level that are associated with burnout and compassion satisfaction among oncology CRCs. Addressing these variables is of critical importance given that oncology CRCs and team-based coordinator care are vital to the success of clinical trials.

RESUMEN

Overfishing of sea cucumber Isostichopus badionotus from Yucatan has led to a major population decline. They are being captured as an alternative to traditional species despite a paucity of information about their health-promoting properties. The transcriptome of the body wall of wild and farmed I. badionotus has now been studied for the first time by an RNA-Seq approach. The functional profile of wild I. badionotus was comparable with data in the literature for other regularly captured species. In contrast, the metabolism of first generation farmed I. badionotus was impaired. This had multiple possible causes including a sub-optimal growth environment and impaired nutrient utilization. Several key metabolic pathways that are important in effective handling and accretion of nutrients and energy, or clearance of harmful cellular metabolites, were disrupted or dysregulated. For instance, collagen mRNAs were greatly reduced and deposition of collagen proteins impaired. Wild I. badionotus is, therefore, a suitable alternative to other widely used species but, at present, the potential of farmed I. badionotus is unclear. The environmental or nutritional factors responsible for their impaired function in culture remain unknown, but the present data gives useful pointers to the underlying problems associated with their aquaculture.

RESUMEN

This study examines the effectiveness of incorporating compassion meditation training into a clinical pastoral education (CPE) curriculum to enhance compassion satisfaction and reduce burnout among hospital chaplain residents. Specifically, a longitudinal, quasi-experimental design was used to examine the impact of Cognitively-Based Compassion Training (CBCT), a group-delivered compassion meditation intervention. Hospital chaplain residents (n = 15) were assigned to participate in a CBCT intervention or a waitlist comparison group. Chaplains assigned to CBCT reported significant decreases in burnout and anxiety compared to the waitlist group; effects were not maintained at 4-month follow-up. Other outcomes, including compassion satisfaction, did not differ significantly but were trending in the expected direction. Findings suggest that compassion meditation training incorporated into CPE promotes chaplain wellbeing, although it may be necessary to extend CBCT throughout residency to sustain effects.

RESUMEN

Sea cucumber body wall contains several naturally occurring bioactive components that possess health-promoting properties. Isostichopus badionotus from Yucatan, Mexico is heavily fished, but little is known about its bioactive constituents. We previously established that I. badionotus meal had potent anti-inflammatory properties in vivo. We have now screened some of its constituents for anti-inflammatory activity in vitro. Glycosaminoglycan and soluble protein preparations reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammatory responses in HaCaT cells while an ethanol extract had a limited effect. The primary glycosaminoglycan (fucosylated chondroitin sulfate; FCS) was purified and tested for anti-inflammatory activity in vivo. FCS modulated the expression of critical genes, including NF-ĸB, TNFα, iNOS, and COX-2, and attenuated inflammation and tissue damage caused by TPA in a mouse ear inflammation model. It also mitigated colonic colitis caused in mice by dextran sodium sulfate. FCS from I. badionotus of the Yucatan Peninsula thus had strong anti-inflammatory properties in vivo.

RESUMEN

Crohn's Disease (CD) and Ulcerative Colitis (UC) are world-wide health problems in which intestinal dysbiosis or adverse functional changes in the microbiome are causative or exacerbating factors. The reduced abundance and diversity of the microbiome may be a result of a lack of exposure to vital commensal microbes or overexposure to competitive pathobionts during early life. Alternatively, many commensal bacteria may not find a suitable intestinal niche or fail to proliferate or function in a protective/competitive manner if they do colonize. Bacteria express a range of factors, such as fimbriae, flagella, and secretory compounds that enable them to attach to the gut, modulate metabolism, and outcompete other species. However, the host also releases factors, such as secretory IgA, antimicrobial factors, hormones, and mucins, which can prevent or regulate bacterial interactions with the gut or disable the bacterium. The delicate balance between these competing host and bacteria factors dictates whether a bacterium can colonize, proliferate or function in the intestine. Impaired functioning of NOD2 in Paneth cells and disrupted colonic mucus production are exacerbating features of CD and UC, respectively, that contribute to dysbiosis. This review evaluates the roles of these and other the host, bacterial and environmental factors in inflammatory bowel diseases.

RESUMEN

22-Oxocholestanes bearing the oxime functionality in the side chain have been synthesized from diosgenin and evaluated in vivo as anti-inflammatory agents in an acute inflammation mouse ear model, against the commercial glucocorticoid dexamethasone. The final compounds were all regioselectively obtained with an E configuration at the oxime double bond. The title compounds reduced ear-induced inflammation and edema. The most active oximes repressed the expression of proinflammatory genes TNF-α, COX-2, and IL-6; including macrophage migration inhibitory factor. Overall, our data suggest that 22-oxocholestane oximes exert a strong in vivo anti-inflammatory activity.

RESUMEN

Background: Alterations in the gut microbiota are strongly associated with the development of inflammatory bowel disease (IBD), particularly with Crohn's disease, which is characterized by reduced abundance of commensal anaerobic bacteria including members of the Bacteroides genus. Our aim was to investigate the protective effects of Bacteroides thetaiotaomicron, an abundant member of this genus, in different rodent models of IBD. Methods: We assessed the effect of B. thetaiotaomicron administration on primary readouts of colitis (weight loss, histopathology, and immune parameters) in dextran sodium sulphate (DSS) and interleukin-10 knockout (IL10KO) models of IBD. Efficacy of a freeze-dried bacterial formulation and a purified recombinant protein of B. thetaiotaomicron was also investigated. Results: B. thetaiotaomicron showed protective effects in both DSS and IL10KO rodent models, as demonstrated by significant amelioration of weight loss, colon shortening, histopathological damage and immune activation. This efficacy was not exclusive to actively growing bacterial preparations but was retained by freeze-dried cells of B. thetaiotaomicron. A pirin-like protein (PLP) of B. thetaiotaomicron, identified by microarray analysis during coculture of the bacterial strain with Caco-2 cells, reduced pro-inflammatory NF-κB signalling in these intestinal epithelial cells. Recombinant PLP partially recapitulated the effect of the whole strain in a rat DSS model. Conclusions: B. thetaiotaomicron displays strong efficacy in preclinical models of IBD and protects against weight loss, histopathological changes in the colon and inflammatory markers. These data indicate that the live strain or its products may be a novel alternative to current treatment options for Crohn's disease.

RESUMEN

OBJECTIVE: Roseburia hominis is a flagellated gut anaerobic bacterium belonging to the Lachnospiraceae family within the Firmicutes phylum. A significant decrease of R. hominis colonization in the gut of ulcerative colitis patients has recently been demonstrated. In this work, we have investigated the mechanisms of R. hominis-host cross talk using both murine and in vitro models. DESIGN: The complete genome sequence of R. hominis A2-183 was determined. C3H/HeN germ-free mice were mono-colonized with R. hominis, and the host-microbe interaction was studied using histology, transcriptome analyses and FACS. Further investigations were performed in vitro and using the TLR5KO and DSS-colitis murine models. RESULTS: In the bacterium, R. hominis, host gut colonization upregulated genes involved in conjugation/mobilization, metabolism, motility, and chemotaxis. In the host cells, bacterial colonization upregulated genes related to antimicrobial peptides, gut barrier function, toll-like receptors (TLR) signaling, and T cell biology. CD4+CD25+FoxP3+ T cell numbers increased in the lamina propria of both mono-associated and conventional mice treated with R. hominis. Treatment with the R. hominis bacterium provided protection against DSS-induced colitis. The role of flagellin in host-bacterium interaction was also investigated. CONCLUSION: Mono-association of mice with R. hominis bacteria results in specific bidirectional gene expression patterns. A set of genes thought to be important for host colonization are induced in R. hominis, while the host cells respond by strengthening gut barrier function and enhancing Treg population expansion, possibly via TLR5-flagellin signaling. Our data reveal the immunomodulatory properties of R. hominis that could be useful for the control and treatment of gut inflammation.

RESUMEN

DNA-based identification of mixed-organism samples offers the potential to greatly reduce the need for resource-intensive morphological identification, which would be of value both to bioassessment and non-native species monitoring. The ability to assign species identities to DNA sequences found depends on the availability of comprehensive DNA reference libraries. Here, we compile inventories for aquatic metazoans extant in or threatening to invade the Laurentian Great Lakes and examine the availability of reference mitochondrial COI DNA sequences (barcodes) in the Barcode of Life Data System for them. We found barcode libraries largely complete for extant and threatening-to-invade vertebrates (100% of reptile, 99% of fish, and 92% of amphibian species had barcodes). In contrast, barcode libraries remain poorly developed for precisely those organisms where morphological identification is most challenging; 46% of extant invertebrates lacked reference barcodes with rates especially high among rotifers, oligochaetes, and mites. Lack of species-level identification for many aquatic invertebrates also is a barrier to matching DNA sequences with physical specimens. Attaining the potential for DNA-based identification of mixed-organism samples covering the breadth of aquatic fauna requires a concerted effort to build supporting barcode libraries and voucher collections.

RESUMEN

BACKGROUND: Chaplaincy is a relatively new discipline in medicine that provides for care of the human spirit in healthcare contexts for people of all worldviews. Studies indicate wide appreciation for its importance, yet empirical research is limited. Our purpose is to create a model of human spiritual processes and needs in palliative care situations so that researchers can locate their hypotheses in a common model which will evolve with relevant findings. METHODS: The Model Building Subgroup worked with the Chaplaincy Research Consortium as part of a larger Templeton Foundation funded project to enhance research in the area. It met with members for an hour on three successive occasions over three years and exchanged drafts for open comment between meetings. All members of the Subgroup agreed on the final draft. RESULTS: The model uses modestly adapted existing definitions and models. It describes the human experience of spirituality during serious illness in three renditions: visual, mathematical, and verbal so that researchers can use whichever is applicable. The visual rendition has four domains: spiritual, psychological, physical and social with process arrows and permeable boundaries between all areas. The mathematical rendition has the same four factors and is rendered as an integral equation, corresponding to an integrative function postulated for the human spirit. In both renditions, the model is notable in its allowance for direct spiritual experience and a domain or factor in its own right, not only experience that is created through the others. The model does not describe anything beyond the human experience. The verbal rendition builds on existing work to describe the processes of the human spirit, relating it to the four domains or factors. CONCLUSIONS: A consensus model of the human spirit to generate hypotheses and evolve based on data has been delineated. Implications of the model for how the human spirit functions and how the chaplain can care for the patient or family caregiver's spiritual coping and well-being are discussed. The next step is to generate researchable hypotheses, results of research from which will give insight into the human spirit and guidance to chaplains caring for it.

RESUMEN

High-throughput screening has become a mainstay of small-molecule probe and early drug discovery. The question of how to build and evolve efficient screening collections systematically for cell-based and biochemical screening is still unresolved. It is often assumed that chemical structure diversity leads to diverse biological performance of a library. Here, we confirm earlier results showing that this inference is not always valid and suggest instead using biological measurement diversity derived from multiplexed profiling in the construction of libraries with diverse assay performance patterns for cell-based screens. Rather than using results from tens or hundreds of completed assays, which is resource intensive and not easily extensible, we use high-dimensional image-based cell morphology and gene expression profiles. We piloted this approach using over 30,000 compounds. We show that small-molecule profiling can be used to select compound sets with high rates of activity and diverse biological performance.
