- Abstract
Health care and religious organizations have a long history with one another. Chaplains' investments in the health and wellbeing of their local communities have extended beyond the hospital walls for longer than many chaplains may recognize. However, the published evidence suggests these efforts have been limited. Given the history of health care evolution in the United States, the small evidence of cases highlighting chaplains' leadership within community health initiatives, and the pressure for health systems to address the social determinants of health, we sought to explore chaplains' integration in community health and wellness initiatives. This paper presents the results of a qualitative analysis of interviews with chaplains working to promote community health and wellness (n = 10). The identified themes highlight factors at the individual chaplain level, such as how chaplains got involved, characteristics of the chaplains' contexts, and the impact of chaplains' involvement.

- Abstract
Background: Clinical Pastoral Education (CPE) is the predominant specialised training for healthcare chaplains in several national contexts. CPE is spiritual care education that uses experiential and action-reflection learning methods to train diverse participants. However, CPE is not established for chaplaincy training in England. Currently, chaplaincy education in England lacks standardisation, leading to inequalities in entry into the profession and inconsistent training and career pathways. CPE has the potential to address these issues. We examined changes associated with participating in CPE and participants' perceptions about their learning experience. We sought to evaluate the effectiveness of CPE as a viable chaplaincy education model in healthcare settings in England., Methods: Convergent mixed methods involved pre-post surveys and focus group sessions to examine the experiences and development of seven chaplains, with diverse experience levels and backgrounds, who participated in the pilot CPE unit in NHS England. We integrated thematic analysis and survey results., Results: We identified four overarching themes: Development pathways, Catalysts for development, Advantages of CPE for chaplaincy education, and Experiences with CPE course structure. Participants developed along various pathways: confidence, reflective practice, emotional intelligence, listening and attending skills, diversity in chaplaincy care, and spiritual assessment. Survey results confirmed several themes, indicating gains in chaplaincy capabilities, emotional intelligence, and counselling self-efficacy. Participants emphasised the advantages and effectiveness of the CPE model., Conclusions: Quantitative and qualitative findings converged to provide rich evidence that CPE generated personal and professional development, improving chaplaincy practice. General learning pathways moved from personal development, through the interpersonal learning context, and translated into chaplain competency. Participants endorsed CPE, as a robust and effective training model for chaplaincy in the English context, for those entering the profession and experienced chaplains alike. We conceptualised preliminary models for chaplain development and learning pathways in CPE that need validation and refinement by future research., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Szilagyi et al.

- Abstract
Ascension, one of the largest Roman Catholic healthcare systems, and Transforming Chaplaincy (TC) collaborated on a research project "Managing Spiritual Care (SC) Departments During the COVID-19 Pandemic: A Qualitative Study." Research participants included 22 leaders from Ascension and TC contacts. Four rounds of individual interviews were conducted from April, 2020 to February, 2021. After issues of race and racial reckoning following George Floyd's murder were brought up spontaneously in interviews, questions on how leaders responded to racial reckoning were added to the subsequent interviews. A secondary analysis examined responses from participants on racial reckoning from interviews 2-4. The objective of this study was to better understand how SC leaders understand their role in issues concerning justice, equity, and inclusion. This study utilized hermeneutic phenomenology methodology. Four phenomenological patterns emerged including: World of Racial Reckoning, Lack of Safety, Creating Safety, and Movement Toward Justice.

- Abstract
Many Clinical Pastoral Education programs pivoted to remote delivery during the COVID-19 pandemic. Our survey explored educators' preparedness, self-efficacy, and views regarding remote Clinical Pastoral Education. Few respondents were either very (14.2%) or not at all (16.5%) prepared. Most were confident facilitating remote learning (69.8%-88.5%), believing remote Clinical Pastoral Education can achieve outcomes equivalent to in-person (59.1%). Six qualitative themes emerged: educator development, educator challenges, remote Clinical Pastoral Education efficacy, remote group dynamics, clinical practice/supervision implications, and benefits and opportunities.

- Abstract
Chaplain leadership may have played a pivotal role in shaping chaplains' roles in health care amidst the COVID-19 pandemic. We convened an international expert panel to identify expert perception on key chaplain leadership factors. Six leadership themes of professional confidence, engaging and trust-building with executives, decision-making, innovation and creativity, building integrative and trusting connections with colleagues, and promoting cultural competencies emerged as central to determining chaplains' integration, perceived value, and contributions during the pandemic.

- Abstract
Clinical Pastoral Education (CPE) programs faced extraordinary challenges during the COVID-19 pandemic. We examined how ACPE-certified educators responded to maintain program delivery. Survey results ( n = 210) suggested a substantial and abrupt increase in remote delivery for CPE instruction and supervised clinical practice, primarily driven by those previously fully in-person. Respondents reported abrupt changes impacted 1152 students. Participants rated their utilization and helpfulness of professional, organizational, and technology resources during the pivot and beyond.

- Abstract
Background: Evidence and clinical guidelines call care team members to address the spiritual well-being of pediatric patients, especially adolescents and young adults (AYA), with cancer and blood disorders. However, the lack of relevant training in generalist spiritual care has been a key barrier. Therefore, we aimed to improve clinicians' capabilities by utilizing the Interprofessional Spiritual Care Education Curriculum (ISPEC) to close this gap in pediatric hematology-oncology. A model of interprofessional spiritual care entails that all team members attend to patients' spirituality by employing generalist spiritual care skills and collaborating with spiritual care specialists such as chaplains., Methods: Interdisciplinary team members providing care for AYA with cancer and blood disorders were recruited to participate in interprofessional spiritual care education. Our intervention combined an evidence-based online curriculum and in-person discussion groups. Pretest-posttest study examined changes in participants' skills and practices to identify, address, and discuss spiritual concerns. Surveys were conducted at baseline and at 1, 3, and 6 months after the intervention., Results: Participants (n = 21) included physicians, advanced practice providers, nurse coordinators, and psychosocial team members. We observed positive changes in participants' ability (36%, P < 0.01), frequency (56%, P = 0.01), confidence (32%, P < 0.01), and comfort (31%, P = 0.02) providing generalist spiritual care baseline versus one month, with significant gains maintained through six months (Omnibus P < 0.05)., Conclusions: Utilizing ISPEC, interprofessional spiritual care education has a strong potential to develop pediatric hematology-oncology team members' capabilities to attend to the spiritual aspect of whole-person care and thus contribute to the well-being of AYA with cancer and blood disorders., (© 2021 The Authors.

- Abstract
We investigated the generation of reactive oxygen species (ROS) from bronchoalveolar lavage (BAL) cells of either control or LPS-exposed rats and the effects of PDE4 inhibitors on ROS production. The PDE4 inhibitors, rolipram and Ariflo (cilomilast, SB 207499) dose-dependently (0.1-10 microm) inhibited fMLP-induced superoxide anion (O(2)(*-)) production (IC(50)s: 0.03 and 0.55 microm, respectively) in BAL cells of Wistar rats collected 3 h after an LPS-aerosol (200 micrograms ml(-1), 1 h). These BAL contained 85-95% neutrophils (BAL cells enriched in neutrophils). In contrast, BAL cells collected at the end of the challenge contained only macrophages and in these conditions, rolipram and Ariflo (0.1-10 microm) could only inhibit 25 and 45% of fMLP-induced O(2)(*-) release, respectively. We also observed that the inhibition of p44/42(MAPK) by PD98059 (1-10 microm) increased O(2)(*-) release by BAL cells enriched in neutrophils, but not by macrophages, and prevented the inhibition of O(2)(*-) production induced by PDE4 inhibitors. Western blot analysis showed that PDE4 inhibitors strongly activated p44/42(MAPK) in BAL cells enriched in neutrophils but not in macrophages. And in these cells, PDE4 and p44/42(MAPK) were co-immunoprecipitated by a polyclonal anti-PDE4 antibody. The following cell permeable-cAMP analogues, dbcAMP (10 microm-1 mm), 8-CPT-cAMP (1 mm) and 8-pMeOPT-2'-O-Me-cAMP (0.5 mm), could not reduce fMLP-induced O(2)(*-) production and both PKA inhibitors, PKA inhibitor 14-22 amide myristoylated (50 nm-1 microm) and H-89 (100 nm-1 microm), did not affect the decrease of O(2)(*-) release induced by PDE4 inhibitors in BAL cells enriched in neutrophils. These data suggest that PDE4 inhibitors decreased fMLP-induced O(2)(*-) release in BAL cells enriched in neutrophils but not in macrophages, through p44/42(MAPK) activation by a cAMP- and a PKA-independent mechanism.

- Abstract
A novel series of benzodiazepine derivatives have been discovered as inhibitors of PDE4 enzymes. We have found that our compounds are selective versus other PDE enzymes, and that the activity can be modulated by specific structural modifications. One compound exhibited a strong eosinophilic infiltration inhibiting action on sensitized Brown-Norway rats (compound 9, 5.1 mg/kg p.o.), moreover this compound is not emetic at 3 mg/kg i.v.

- Abstract
A somatostatin-14-degrading activity has been purified to homogeneity from rat pure pancreatic juice. This proteinase was concentrated more than 350-fold in a four-step procedure including ion-exchange and gel filtration. The final preparation contained a single protein with a molecular weight (M(r)) of approx. 29,000, as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The determination of its NH2-terminal sequence led us to conclude that the purified proteinase corresponds to the rat pancreatic elastase II predicted from the cDNA clone isolated by MacDonald in 1982. This anionic proteinase exhibits an isoelectric point of 5.6 and does not contain any carbohydrate moieties in its structure. The proteinase is sensitive to the trypsin inhibitors soybean trypsin inhibitor and N alpha-tosyl-L-lysine-chloromethyl ketone and also to 3,4-dichloroisocoumarin, a general elastase inhibitor. The cleavage products obtained after hydrolysis of somatostatin-14 by the purified elastase, were separated by reversed phase high performance liquid chromatography and identified by amino-acid analysis. The primary hydrolysis was trypsin-like and consisted in an opening of the cyclic structure of somatostatin-14 after the Lys-9 residue leading to the formation of a Y-shaped peptide with the same amino-acid composition as the native peptide. The initial 'trypsin-like specificity' was not observed during the secondary hydrolysis of the Y-shaped peptide; indeed the proteinase seemed more specific for a certain motif in the native peptide rather than for a specific class of amino acid, this last kind of selectivity is commonly observed with trypsin and chymotrypsin. In order to establish that the proteinase possesses an extended recognition site on the substrate rather than a specificity for a class of amino acid, the substrate specificity of the rat pancreatic elastase II was investigated with a series of para-nitroanilide peptides. The proteinase exhibits a large specificity involving peptide chain of at least four amino acids with a preference for bulky residue in P1 or P2. The Km values of 89 microM and 1567 microM obtained for somatostatin-14 and Suc-Ala-Ala-Pro-Met-pNA, respectively, indicate that elastase II has a greater affinity for the natural substrate than for synthetics. This last observation along with the substrate specificity of the proteinase leads us to propose that elastase II could be specifically involved in the regulation of biological functions of somatostatin-14 in the gastrointestinal tract.
