Technology-Assisted, Group-Based CBT for Rural Adults' Depression: Open Pilot Trial Results.

Purpose: This pilot study assesses the association of Raising Our Spirits Together (ROST), a technology-assisted, group-based cognitive behavioral therapy for depression, with rural adults' depressive symptoms and anxiety. Method: Nine adults from rural Michigan participated in an open pilot of ROST. Clergy facilitated pilot groups. The pilot began in February 2020 in-person. Due to COVID-19, the pilot was completed virtually. Results: Mean depressive symptom scores, based on the PHQ-9, significantly decreased from pre-treatment (M = 14.4) to post-treatment (M = 6.33; t (8) = 6.79; P < .001). Symptom reduction was maintained at 3-month follow-up (M = 8.00), with a significant pattern of difference in depressive symptoms over time (F(2) = 17.7; P < .001; eta-squared = .689). Similar patterns occurred for anxiety based on the GAD-7. Participants attended an average of 7.33 of 8 sessions. Fidelity ratings were excellent. Discussion: ROST is a potentially feasible intervention for rural adults' depressive symptoms. ROST offers a promising model for increasing treatment access and building capacity in rural areas.

Première vague de la COVID-19 au Québec : motivation du personnel soignant à traiter des patients infectés.

INTRODUCTION: Retention of healthcare workers (HCWs) in the healthcare system during the COVID-19 pandemic could become a challenge. It is therefore important to better understand what are the motivational elements that could explain a greater or lesser motivation to care for infected patients. OBJECTIVES: To evaluate factors modulating HCWs' willingness to treat COVID-19 infected patients. METHODS: HCWs from Québec, Canada, were invited to complete an online survey during the first wave of the COVID-19 pandemic between the months of April and July 2020. The survey focused on the intention to avoid treating infected patients, prior experiences in treating COVID-19 patients and anxiety levels. Descriptive statistics and multiple regression analysis were used to assess which factors explained differences in HCWs intention to avoid treating patients. RESULTS: A total of 430 HCW completed the survey. A majority were women (87%) and nurses (50%). Of those, 12% indicated having considered measures to avoid working with COVID-19 infected patients and 5% indicated having taken actions to avoid working with infected patients. A further 18% indicated that they would use a hypothetical opportunity to avoid working with infected patients. Having previously treated infected patients was associated with a significant reduction in the intention to avoid work (OR: 0.56 CI 0.36-0.86). Amongst HCWs, physicians had a significantly reduced intention to avoid treating infected patients (OR: 0.47 CI 0.23-0.94). We also found that an increase in anxiety score was associated with a greater intention to avoid treating COVID-19 infected patients (OR: 1.06 CI 1.04-1.08). CONCLUSION: Study results suggest that previous experience in treating COVID-19 infected patients is protective in terms of work-avoidance intentions. We also found that amongst HCWs, physicians had a significantly lower intention to avoid working with COVID-19 infected patients. Finally, our results show that increase in anxiety is associated with a higher intention to avoid treating infected patients. Characterization of factors associated with low anxiety levels and low reluctance to work during the COVID-19 pandemic could be useful in staffing facilities during the present and future healthcare crisis.

Randomized trial of routine versus on-demand intraoperative extracorporeal membrane oxygenation in lung transplantation: A feasibility study.

In most centers, extracorporeal membrane oxygenation (ECMO) is the preferred means to provide cardiopulmonary support during lung transplantation. However, there is controversy about whether intraoperative venoarterial (VA) ECMO should be used routinely or selectively. A randomized controlled trial is the best way to address this controversy. In this publication, we describe a feasibility study to assess the practicality of a protocol comparing routine versus selective VA-ECMO during lung transplantation. This prospective, single-center, randomized controlled trial screened all patients undergoing lung transplantation. Exclusion criteria include retransplantation, multiorgan transplantation, and cases where ECMO is mandatory. We determined that the trial would be feasible if we could recruit 19 participants over 6 months with less than 10% protocol violations. Based on the completed feasibility study, we conclude that the protocol is feasible and safe, giving us the impetus to pursue a multicenter trial with little risk of failure due to low recruitment.

Study protocol: A randomized controlled trial of Raising Our Spirits Together, an entertaining, group-based technology-assisted cognitive behavioral therapy for depression, tailored for rural adults and delivery by clergy.

This paper presents a methodological description of a randomized controlled trial (RCT) testing the effect of Raising Our Spirits Together (ROST), a technology-assisted cognitive behavioral therapy (T-CBT) for depression, tailored for the rural context and for delivery by clergy, compared to an enhanced control condition. Depression is among the most common mental health conditions; yet the majority of adults with depression do not receive needed treatment due to limited access to mental health professionals, treatment-associated costs, distance to care, and stigma. These barriers are particularly salient in rural areas of the United States. T-CBT with human support is an accessible and effective treatment for depression; however, currently available T-CBTs have poor completion rates due to the lack of tailoring and other features to support engagement. ROST is a T-CBT specifically tailored for the rural setting and delivery by clergy, who are preferred, informal providers. ROST also presents core CBT content in a simple, jargon-free manner that supports multiple learning preferences. ROST is delivered virtually in a small group format across 8 weekly sessions via videoconferencing software consistent with other clergy-based programs, such as Bible studies or self-help groups. In this study, adults with depressive symptoms recruited from two rural Michigan counties will be randomized to receive ROST versus an enhanced control condition (N = 84). Depressive symptoms post-treatment and at 3 months follow-up according to the Patient Health Questionnaire (PHQ-9) will be the primary outcome. Findings will determine whether ROST is effective for improving depression symptoms in underserved, under resourced rural communities.

Correlation between Neutrophil Extracellular Traps (NETs) Expression and Primary Graft Dysfunction Following Human Lung Transplantation.

Primary graft dysfunction (PGD) is characterized by alveolar epithelial and vascular endothelial damage and inflammation, lung edema and hypoxemia. Up to one-third of recipients develop the most severe form of PGD (Grade 3; PGD3). Animal studies suggest that neutrophils contribute to the inflammatory process through neutrophil extracellular traps (NETs) release (NETosis). NETs are composed of DNA filaments decorated with granular proteins contributing to vascular occlusion associated with PGD. The main objective was to correlate NETosis in PGD3 (n = 9) versus non-PGD3 (n = 27) recipients in an exploratory study. Clinical data and blood samples were collected from donors and recipients pre-, intra- and postoperatively (up to 72 h). Inflammatory inducers of NETs' release (IL-8, IL-6 and C-reactive protein [CRP]) and components (myeloperoxidase [MPO], MPO-DNA complexes and cell-free DNA [cfDNA]) were quantified by ELISA. When available, histology, immunohistochemistry and immunofluorescence techniques were performed on lung biopsies from donor grafts collected during the surgery to evaluate the presence of activated neutrophils and NETs. Lung biopsies from donor grafts collected during transplantation presented various degrees of vascular occlusion including neutrophils undergoing NETosis. Additionally, in recipients intra- and postoperatively, circulating inflammatory (IL-6, IL-8) and NETosis biomarkers (MPO-DNA, MPO, cfDNA) were up to 4-fold higher in PGD3 recipients compared to non-PGD3 (p = 0.041 to 0.001). In summary, perioperative elevation of NETosis biomarkers is associated with PGD3 following human lung transplantation and these biomarkers might serve to identify recipients at risk of PGD3 and initiate preventive therapies.

How anxious were Quebec healthcare professionals during the first wave of the COVID-19 pandemic? A web-based cross-sectional survey.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic may cause significant anxiety among healthcare professionals (HCPs). COVID-19-related psychological impacts on HCPs in Western countries have received relatively little attention. OBJECTIVE: This study aims to assess the levels of anxiety in HCPs working in the province of Quebec (Canada) during the first wave of the COVID-19 pandemic and identify factors associated with changes in anxiety scores. METHODS: An exploratory online cross-sectional survey was conducted among Quebec HCPs from April to July 2020. The Spielberger's State-Trait Anxiety Inventory (STAI) was used to measure state anxiety among HCPs. Descriptive and multivariate analyses were performed. RESULTS: A total of 426 HCPs completed the survey. Anxiety scores ranged from 20 to 75 points, with 80 being the highest possible value on the STAI scale. Being a female HCP [B = 5.89, 95% confidence interval (CI): 2.49-9.3] and declaring having the intention to avoid caring for patients with COVID-19 (B = 3.75, 95% CI: 1.29-6.22) were associated with increased anxiety scores. Having more years of experience was associated with decreased anxiety scores [B = -0.2, 95% CI: -0.32-(-0.08)]. CONCLUSION: Organizational strategies aimed at preventing and relieving anxiety should target junior female HCPs who express the intention to avoid caring for patients with COVID-19. Seniority could become an important criterion in selecting frontline HCPs during pandemics. Further studies are needed to comprehensively examine the impacts of the COVID-19 pandemic on Canadian HCPs and identify evidence-based coping strategies.

HSP90 Inhibitor Improves Lung Protection in Porcine Model of Donation After Circulatory Arrest.

BACKGROUND: Ischemia-reperfusion associated with prolonged warm ischemia during donation after circulatory death (DCD) induces acute lung injury. The objective of this study was to combine ex vivo lung perfusion (EVLP) and a heat shock protein-90 inhibitor (HSP90i) to recondition DCD organs and prevent primary graft dysfunction. METHODS: Pigs (55 to 65 kg) were anesthetized, ventilated, and hemodynamically monitored. Cardiac arrest was induced with potassium chloride, and animals were left nonventilated for 2 hours. Lungs were procured and perfused in an EVLP platform for 4 hours by using a cellular perfusate. In the study group, the perfusate contained HSP90i and its transport vehicle (n = 4). In the control group, the perfusate contained only the transport vehicle (n = 4). Gas exchange, airway pressures, and compliance were measured. Pulmonary edema was assessed by bronchoscopy and weight measurement. Lung biopsy samples were obtained for histologic analyses and protein expression measurements. RESULTS: The use of HSP90i reduced lung weight gain to 8.4 ± 3.4% vs 26.6 ± 6.2% in the control group (P < .05). There was reduced edema formation. The ratio of the partial pressure of arterial oxygen to the fraction of inspired oxygen at the end of EVLP was 423 ± 65 in the study group vs 339 ± 25 mm Hg in the control group, but this difference was not statistically significant. Lactate metabolism, pulmonary vascular resistance, and pulmonary arterial pressure improved during EVLP with the use of the HSP90i. CONCLUSIONS: The use of HSP90i with EVLP improves the lung reconditioning process. Further research is required to confirm whether these findings translate to benefit once transplanted and observed in vivo. Successful pharmacologic inhibitors may expand the donor pool in the context of DCD donors.

Aluminum contamination of parenteral nutrition and aluminum loading in children on long-term parenteral nutrition.

BACKGROUND: Children who are receiving parenteral nutrition are at risk of aluminum overload, which may contribute to such side effects as osteopenic bone disease. The aim of the present study is to determine the aluminum contamination of parenteral nutrition solutions and their components, and to assess the aluminum status of children on long-term parenteral nutrition. METHODS: Aluminum concentrations were determined by graphite furnace absorption spectroscopy in components and in final parenteral nutrition solutions. The urinary aluminum excretion and plasma aluminum concentration were determined in 10 children on long-term parenteral nutrition. RESULTS: The mean aluminum concentration in the administered parenteral nutrition solutions was 1.6 +/- 0.9 micromol x l(-1)(mean +/- standard deviation (SD)). The resulting mean aluminum daily intake of the 10 patients was 0.08 +/- 0.03 micromol x kg(-1) x day(-1). CONCLUSIONS: Compared to two previous studies performed in 1990 and in 1995 in our hospital, the aluminum contamination of parenteral nutrition solutions and the daily aluminum intake of the children seemed to decrease. However, the plasma aluminum concentration and daily urinary aluminum excretion of the children still remain above normal standards. The children had no clinical symptoms of bone disease but aluminum accumulation in tissue can not be excluded. To prevent this iatrogenic toxicity, the aluminum contamination of parenteral nutrition should be assessed regularly.
