Importance To our knowledge, this is the first clinical trial designed to investigate concurrent treatment with a checkpoint inhibitor and conventional chemotherapy in relapsed or refractory classic Hodgkin lymphoma in patients destined for an autologous stem cell transplant. Objective To evaluate the complete response rate as assessed by ¹⁸ F-fluorodeoxyglucose–positron emission tomography with computed tomography (FDG-PET/CT) after salvage therapy for patients with relapsed or refractory classic Hodgkin lymphoma. Design, Setting, and Participants A single-group, phase 2, multi-institutional nonrandomized clinical trial to evaluate the addition of pembrolizumab to ifosfamide, carboplatin, and etoposide (ICE) chemotherapy was conducted from April 20, 2017, to October 29, 2020, at 5 US sites. The 42 patients were aged 18 years or older, with an Eastern Cooperative Oncology Group Performance Status Scale score of 0 or 1 and biopsy-proven relapsed or refractory classic Hodgkin lymphoma after 1 or 2 prior lines of chemotherapy. Patients were required to be appropriate candidates for transplant, with measurable lesions detected by FDG-PET/CT. Interventions Two cycles of pembrolizumab (200 mg intravenously on day 1) with ICE chemotherapy every 21 days, followed by stem cell mobilization and collection, and then 1 cycle of pembrolizumab monotherapy followed by FDG-PET/CT response assessment. Main Outcomes and Measures The primary end point was complete response rate detected by FDG-PET/CT, defined as a Deauville score of 3 or lower. Patients with a complete response proceeded to an autologous stem cell transplant. Secondary end points included progression-free survival, overall survival, stem cell mobilization, and neutrophil and platelet engraftment. Adverse events were monitored to assess safety. Results Forty-two patients were enrolled, with 37 evaluable for the primary end point. The median age was 34 years (range, 19-70 years), 25 patients were female (68%), 6 were African American (16%), and 26 were White (70%). The complete response rate for the 37 patients assessed by FDG-PET/CT imaging was 86.5% (95% CI, 71.2%-95.5%); the overall response rate was 97.3% (36 patients), with 10.8% partial responses (4 patients). New areas of FDG-PET positivity in 2 patients were biopsied, showing noncaseating granuloma in 1 case and a reactive lymph node in a second. Progression-free survival and overall survival 2-year estimates were 87.2% (32 patients; 95% CI, 77.3%-98.3%) and 95.1% (95% CI, 88.8%-100%), respectively. The addition of pembrolizumab to ICE chemotherapy did not negatively affect stem cell mobilization or collection or engraftment, similar to prior experience in this patient population and setting. Conclusions and Relevance Results suggest that the addition of pembrolizumab to ICE chemotherapy was well tolerated and highly effective in comparison with prior reports of chemotherapy-only regimens, supporting further investigation in patients with relapsed or refractory classic Hodgkin lymphoma eligible for an autologous stem cell transplant.

Objective Cancer survivors face numerous physical and mental health challenges even after treatment completion. However, few studies have examined mental health in cancer survivors who received curative treatment during the transition out of active treatment and into survivorship. The current study describes the prevalence of mental health outcomes and their correlates in cancer survivors treated with curative intent during the first year of survivorship. Methods A total of 120 cancer survivors of any cancer type completed a survey that assessed depression, anxiety, death ideation, alcohol and substance use, and demographic characteristics. Data regarding cancer type and treatment were extracted from the medical record. Results Approximately 15% of the sample reported depression symptoms. Fifteen percent also reported anxiety symptoms in the past two weeks. 10 percent of the sample reported experiencing death ideation since their treatment ended and 7.5% reported death ideation in the past two weeks. Younger age, previous psychiatric diagnosis, and current substance use were associated with reports of depression symptoms, anxiety symptoms, and death ideation. Conclusion Cancer survivors entering survivorship after curative treatment experience elevated prevalence of depressive symptoms, anxiety symptoms, and death ideation. Younger cancer survivors and those with previous psychiatric diagnoses or substance use may be at particular risk for mental health problems during the first year of survivorship. Future research should further examine modifiable risk factors for depression, anxiety, and death ideation in cancer survivors at the transition into survivorship after curative treatment in order to improve survivorship care within both oncology and primary care.

Background The SAGES University Colorectal Masters Program is a structured educational curriculum that is designed to aid practicing surgeons develop and maintain knowledge and technical skills for laparoscopic colorectal surgery. The Colorectal Pathway is based on three anchoring procedures (laparoscopic right colectomy, laparoscopic left and sigmoid colectomy for uncomplicated and complex disease, and intracorporeal anastomosis for minimally invasive right colectomy) corresponding to three levels of performance (competency, proficiency and mastery). This manuscript presents focused summaries of the top 10 seminal articles selected for laparoscopic left and sigmoid colectomy for complex benign and malignant disease. Methods A systematic literature search of Web of Science for the most cited articles on the topic of laparoscopic complex left/sigmoid colectomy yielded 30 citations. These articles were reviewed and ranked by the SAGES Colorectal Task Force and invited subject experts according to their citation index. The top 10 ranked articles were then reviewed and summarized, with emphasis on relevance and impact in the field, study findings, strength and limitations and conclusions. Results The top 10 seminal articles selected for the laparoscopic left/sigmoid colectomy for complex disease anchoring procedure include advanced procedures such as minimally invasive splenic flexure mobilization techniques, laparoscopic surgery for complicated and/or diverticulitis, splenic flexure tumors, complete mesocolic excision, and other techniques (e.g., Deloyers or colonic transposition in cases with limited colonic reach after extended left-sided resection). Conclusions The SAGES Colorectal Masters Program top 10 seminal articles selected for laparoscopic left and sigmoid colectomy for complex benign and malignant disease anchoring procedure are presented. These procedures were the most essential in the armamentarium of practicing surgeons that perform minimally invasive surgery for complex left and sigmoid colon pathology.

Context.—: Unicentric Castleman disease (UCD) is a dynamic entity with a wide spectrum of morphologic findings. UCD can be further subdivided into hyaline-vascular and mixed/plasmacytic variants. Hyaline-vascular UCD has both follicular and interfollicular (stromal) changes, and occasionally these lesions show a skewed representation of either the follicular or stromal compartments. Plasmacytosis is usually minimal in hyaline-vascular variant. Mixed/plasmacytic variant of UCD is composed of sheets of plasma cells often associated with a variable number of follicles with regressive changes. Objective.—: To illustrate the differential diagnosis of UCD, as it is quite broad and includes lymphomas, plasma cell neoplasms and stromal neoplasms such as follicular dendritic cell sarcoma and vascular neoplasms, immunoglobulin G4-related disease, infections, and other rare lesions. An additional objective is to enhance awareness of the morphologic features of UCD in excisional and in small core-needle biopsy specimens, the latter of which may inadvertently target follicle- or stroma-rich areas, causing diagnostic challenges. Data sources.—: In this review, we provide the readership a concise illustration of the morphologic spectrum of UCD that we have encountered in our practice and a brief discussion of entities in the differential diagnosis. Conclusions.—: UCD exhibits a broad spectrum of morphologic changes, and awareness of these morphologic variations is key to avoid misdiagnosis.

Purpose of Review It is widely recognized that nutrition plays an important role in disease prevention and management; however, formal physician education in nutrition still lags behind recommended national guidelines. As experts of digestion and metabolism, gastroenterologists are uniquely positioned to incorporate nutrition into clinical care. Gastroenterology fellowship presents itself as a unique time to capture trainees for more formalized education in nutrition and obesity which can then be implemented in practice. Recent Findings Recent literature suggests a large knowledge gap regarding foundational nutritional concepts among gastroenterology trainees, a result of limited education and exposure. Summary The following is an overview of current trends in nutrition education both broadly and in gastroenterology fellowships with a comprehensive review of current educational tools, curriculum design, implementation in practice, and future directions.

Macrophages, the major component of the mononuclear phagocyte system, uptake and clear systemically administered nanoparticles (NPs). Therefore, leveraging macrophages as a druggable target may be advantageous to enhance NP-mediated drug delivery. Despite many studies focused on NP-cell interactions, NP-mediated macrophage polarization mechanisms are still poorly understood. This work aimed to explore the effect of NP physicochemical parameters (size and charge) on macrophage polarization. Upon exposure to biological fluids, proteins rapidly adsorb to NPs and form protein coronas. To this end, we hypothesized that NP protein coronas govern NP-macrophage interactions, uptake, and subsequent macrophage polarization. To test this hypothesis, model polystyrene NPs with various charges and sizes, as well as NPs relevant to drug delivery, were utilized. Data suggest that cationic NPs potentiate both M1 and M2 macrophage markers, while anionic NPs promote M1-to-M2 polarization. Additionally, anionic polystyrene nanoparticles (APNs) of 50 nm exhibit the greatest influence on M2 polarization. Proteomics was pursued to further understand the effect of NPs physicochemical parameters on protein corona, which revealed unique protein patterns based on NP charge and size. Several proteins impacting M1 and M2 macrophage polarization were identified within cationic polystyrene nanoparticles (CPNs) corona, while APNs corona included fewer M1 but more M2-promoting proteins. Nevertheless, size impacts protein corona abundance but not identities. Altogether, protein corona identities varied based on NP surface charge and correlated to dramatic differences in macrophage polarization. In contrast, NP size differentially impacts macrophage polarization, which is dominated by NP uptake level rather than protein corona. In this work, specific corona proteins were identified as a function of NP physicochemical properties. These proteins are correlated to specific macrophage polarization programs and may provide design principles for developing macrophage-mediated NP drug delivery systems.

Prior research establishing that bone interacts in coordination with the bone marrow microenvironment (BMME) to regulate hematopoietic homeostasis was largely based on analyses of individual bone-associated cell populations. Recent advances in intravital imaging has suggested that the expansion of hematopoietic stem cells (HSCs) and acute myeloid leukemia cells is restricted to bone marrow microdomains during a distinct stage of bone remodeling. These findings indicate that dynamic bone remodeling likely imposes additional heterogeneity within the BMME to yield differential clonal responses. A holistic understanding of the role of bone remodeling in regulating the stem cell niche and how these interactions are altered in age-related hematological malignancies will be critical to the development of novel interventions. To advance this understanding, herein, we provide a synopsis of the cellular and molecular constituents that participate in bone turnover and their known connections to the hematopoietic compartment. Specifically, we elaborate on the coupling between bone remodeling and the BMME in homeostasis and age-related hematological malignancies and after treatment with bone-targeting approaches. We then discuss unresolved questions and ambiguities that remain in the field.

In the current literature, clinical registry cohorts related to ocular inflammation are few and far between, and there are none involving multi-continental international data. Many existing registries comprise administrative databases, data related to specific uveitic diseases, or are designed to address a particular clinical problem. The existing data, although useful and serving their intended purposes, are segmented and may not be sufficiently robust to design prognostication tools or draw epidemiological conclusions in the field of uveitis and ocular inflammation. To solve this, we have developed the Ocular Autoimmune Systemic Inflammatory Infectious Study (OASIS) Clinical Registry. OASIS collects prospective and retrospective data on patients with all types of ocular inflammatory conditions from centers all around the world. It is a primarily web-based platform with alternative offline modes of access. A comprehensive set of clinical data ranging from demographics, past medical history, clinical presentation, working diagnosis to visual outcomes are collected over a range of time points. Additionally, clinical images such as optical coherence tomography, fundus fluorescein angiography and indocyanine green angiography studies may be uploaded. Through the capturing of diverse, well-structured, and clinically meaningful data in a simplified and consistent fashion, OASIS will deliver a comprehensive and well organized data set ripe for data analysis. The applications of the registry are numerous, and include performing epidemiological analysis, monitoring drug side effects, and studying treatment safety efficacy. Furthermore, the data compiled in OASIS will be used to develop new classification and diagnostic systems, as well as treatment and prognostication guidelines for uveitis.

The etiologies of Parkinson’s disease (PD) remain unclear. Some, such as certain genetic mutations and head trauma, are widely known or easily identified. However, these causes or risk factors do not account for the majority of cases. Other, less visible factors must be at play. Among these is a widely used industrial solvent and common environmental contaminant little recognized for its likely role in PD: trichloroethylene (TCE). TCE is a simple, six-atom molecule that can decaffeinate coffee, degrease metal parts, and dry clean clothes. The colorless chemical was first linked to parkinsonism in 1969. Since then, four case studies involving eight individuals have linked occupational exposure to TCE to PD. In addition, a small epidemiological study found that occupational or hobby exposure to the solvent was associated with a 500% increased risk of developing PD. In multiple animal studies, the chemical reproduces the pathological features of PD. Exposure is not confined to those who work with the chemical. TCE pollutes outdoor air, taints groundwater, and contaminates indoor air. The molecule, like radon, evaporates from underlying soil and groundwater and enters homes, workplaces, or schools, often undetected. Despite widespread contamination and increasing industrial, commercial, and military use, clinical investigations of TCE and PD have been limited. Here, through a literature review and seven illustrative cases, we postulate that this ubiquitous chemical is contributing to the global rise of PD and that TCE is one of its invisible and highly preventable causes. Further research is now necessary to examine this hypothesis.

Background Epidemiological studies demonstrate an association between kidney stones and risk for chronic kidney disease (CKD) and CKD progression. Metabolic acidosis, as a consequence of CKD, results in a reduced urine pH which promotes the formation of some types of kidney stones and inhibits the formation of others. While metabolic acidosis is a risk factor for CKD progression, the association of serum bicarbonate with risk of incident kidney stones is not well understood. Methods We used an Integrated Claims-Clinical dataset of US patients to generate a cohort of patients with non-dialysis-dependent CKD with 2 serum bicarbonate values 12 to <22 mmol/L (metabolic acidosis) or 22 to <30 mmol/L (normal serum bicarbonate). Primary exposure variables were baseline serum bicarbonate and change in serum bicarbonate over time. Cox proportional hazards models evaluated time to first occurrence of kidney stones during a median 3.2-year follow-up. Results 142 884 patients qualified for the study cohort. Patients with metabolic acidosis experienced post-index date kidney stones at greater frequency than patients with normal serum bicarbonate at the index date (12.0% vs 9.5%, P < 0.0001). Both lower baseline serum bicarbonate (hazard ratio [HR] 1.047; 95% confidence interval [CI] 1.036–1.057) and decreasing serum bicarbonate over time (HR 1.034; 95% CI 1.026–1.043) were associated with increased risk of kidney stone development. Conclusions Metabolic acidosis was associated with a higher incidence of kidney stones and shorter time to incident stone formation in patients with CKD. Future studies may investigate the role of correcting metabolic acidosis to prevent stone formation.

Objectives: This practice parameter was revised collaboratively by the American College of Radiology (ACR) and the American Radium Society (ARS). This practice parameter provides updated reference literature regarding both clinical-based conventional total body irradiation and evolving volumetric modulated total body irradiation. Methods: This practice parameter was developed according to the process described under the heading The Process for Developing ACR Practice Parameters and Technical Standards on the ACR website (https://www.acr.org/Clinical-Resources/Practice-Parameters-and-Technical-Standards) by the Committee on Practice Parameters-Radiation Oncology of the ACR Commission on Radiation Oncology in collaboration with the ARS. Results: This practice parameter provides a comprehensive update to the reference literature regarding conventional total body irradiation and modulated total body irradiation. Dependence on dose rate remains an active area of ongoing investigation in both the conventional setting (where instantaneous dose rate can be varied) and in more modern rotational techniques, in which average dose rate is the relevant variable. The role of imaging during patient setup and the role of inhomogeneity corrections due to computer-based treatment planning systems are included as evolving areas of clinical interest notably surrounding the overall dose inhomogeneity. There is increasing emphasis on the importance of evaluating mean lung dose as it relates to toxicity during high-dose total body irradiation regimens. Conclusions: This practice parameter can be used as an effective tool in designing and evaluating a total body irradiation program that successfully incorporates the close interaction and coordination among the radiation oncologists, medical physicists, dosimetrists, nurses, and radiation therapists.

Background: Nasal airway obstruction (NAO) is a highly prevalent disorder. Septal swell body (SSB) hypertrophy is an often-overlooked contributor to NAO. SSB treatment may relieve symptoms of NAO. The objective of this study was to assess the clinical use of a temperature-controlled radiofrequency (TCRF) device to treat SSBs to improve symptoms in adults with NAO. Methods: In this prospective, multicenter, open-label, single arm study, patients with severe or extreme NAO related to SSB hypertrophy received bilateral TCRF treatment in the SSB area. The primary endpoint was improvement in Nasal Obstruction Symptom Evaluation (NOSE) scale scores from baseline to 3 months post-procedure. A subset of study patients underwent computed tomography (CT) imaging to evaluate post-treatment changes in SSB size. Results: Mean NOSE scale scores significantly improved from 73.5 (SD 14.2) at baseline to 27.9 (SD 17.2) at 3 months post-procedure; a reduction of -45.3 (SD 21.4), (95% confidence interval [CI]: -50.4 to -40.1; p< 0.0001): the responder rate was 95.7% (95% CI: 0.88 to 0.99; p < 0.0001). CT evaluation at 3 months showed statistically significant reductions in the SSB with the greatest reduction in the middle thickness: (mean change -3.4 [SD 1.8] millimeters [95% CI: -4.0 to -2.8; p<.0001]). Minimal adverse events with any relationship to the device or procedure were reported, none were serious in nature and no septal perforations occurred. Conclusions: This study demonstrates that temperature-controlled radiofrequency treatment of SSB hypertrophy is well-tolerated and effective at reducing both SSB size and symptoms of NAO at 3 months post-treatment.

Obesity affects millions of people worldwide and is associated with an increased risk of cognitive decline. The glymphatic system is a brain-wide metabolic waste clearance system, dysfunction of which is linked to dementia. We herein examined glymphatic transport in mice with long-term obesity induced by a high-fat diet for 10 months. The obese mice developed hypertension and elevated heart rate, neuroinflammation and gliosis, but not apparent systemic inflammation. Surprisingly, glymphatic inflow was globally unaffected by the high-fat diet except for the hypothalamus, which displayed increased influx and elevated AQP4 vascular polarization compared to the normal weight control group. We propose that a long-term high-fat diet induced metabolic alteration of hypothalamic neurons and neuroinflammation, which in turn enhanced glymphatic clearance in the effected brain region.

Background Utilizing a 1-year chart review as the data, Furo et al. conducted a research study on an association between buprenorphine dose and the urine “norbuprenorphine” to “creatinine” ratio and found significant differences in the ratio among 8-, 12-, and 16-mg/day groups with an analysis of variance (ANOVA) test. This study expands the data for a 2-year chart review and is intended to delineate an association between buprenorphine dose and the urine “norbuprenorphine” to “creatinine” ratio with a higher statistical power. Methods This study performed a 2-year chart review of data for the patients living in a halfway house setting, where their drug administration was closely monitored. The patients were on buprenorphine prescribed at an outpatient clinic for opioid use disorder (OUD), and their buprenorphine prescription and dispensing information were confirmed by the New York Prescription Drug Monitoring Program (PDMP). Urine test results in the electronic health record (EHR) were reviewed, focusing on the “buprenorphine,” “norbuprenorphine,” and “creatinine” levels. The Kruskal–Wallis H and Mann–Whitney U tests were performed to examine an association between buprenorphine dose and the “norbuprenorphine” to “creatinine” ratio. Results This study included 371 urine samples from 61 consecutive patients and analyzed the data in a manner similar to that described in the study by Furo et al. This study had similar findings with the following exceptions: (1) a mean buprenorphine dose of 11.0 ± 3.8 mg/day with a range of 2 to 20 mg/day; (2) exclusion of 6 urine samples with “creatinine” level <20 mg/dL; (3) minimum “norbuprenorphine” to “creatinine” ratios in the 8-, 12-, and 16-mg/day groups of 0.44 × 10 ⁻⁴ (n = 68), 0.1 × 10 ⁻⁴ (n = 133), and 1.37 × 10 ⁻⁴ (n = 82), respectively; however, after removing the 2 lowest outliers, the minimum “norbuprenorphine” to “creatinine” ratio in the 12-mg/day group was 1.6 × 10 ⁻⁴ , similar to the findings in the previous study; and (4) a significant association between buprenorphine dose and the urine “norbuprenorphine” to “creatinine” ratios from the Kruskal-Wallis test ( P < .01). In addition, the median “norbuprenorphine” to “creatinine” ratio had a strong association with buprenorphine dose, and this association could be formulated as: [y = 2.266 ln( x) + 0.8211]. In other words, the median ratios in 8-, 12-, and 16-mg/day groups were 5.53 × 10 ⁻⁴ , 6.45 × 10 ⁻⁴ , and 7.10 × 10 ⁻⁴ , respectively. Therefore, any of the following features should alert providers to further investigate patient treatment compliance: (1) inappropriate substance(s) in urine sample; (2) “creatinine” level <20 mg/dL; (3) “buprenorphine” to “norbuprenorphine” ratio >50:1; (4) buprenorphine dose >24 mg/day; or (5) “norbuprenorphine” to “creatinine” ratios <0.5 × 10 ⁻⁴ in patients who are on 8 mg/day or <1.5 × 10 ⁻⁴ in patients who are on 12 mg/day or more. Conclusion The results of the present study confirmed those of the previous study regarding an association between buprenorphine dose and the “norbuprenorphine” to “creatinine” ratio, using an expanded data set. Additionally, this study delineated a clearer relationship, focusing on the median “norbuprenorphine” to “creatinine” ratios in different buprenorphine dose groups. These results could help providers interpret urine test results more accurately and apply them to outpatient opioid treatment programs for optimal treatment outcomes.

Introduction: Paranoia is a common and impairing psychosis symptom, which exists along a severity continuum that extends into the general population. Individuals at clinical high-risk for psychosis (CHR) frequently experience paranoia and this may elevate their risk for developing full psychosis. Nonetheless, limited work has examined the efficient measurement of paranoia in CHR individuals. The present study aimed to validate an often used self-report measure, the Revised Green Paranoid Thoughts Scale (RGPTS), in this critical population. Method: Participants were CHR individuals (n = 103), mixed clinical controls (n = 80), and healthy controls (n = 71) who completed self-report and interview measures. Confirmatory factor analysis (CFA), psychometric indices, group differences, and relations to external measures were used to evaluate the reliability and validity of the RGPTS. Results: CFA replicated a two-factor structure for the RGPTS and the associated Reference and Persecution scales were reliable. CHR individuals scored significantly higher on both Reference and Persecution, relative to both healthy (ds = 1.03, .86) and clinical controls (ds = .64, .73). In CHR participants, correlations between Reference and Persecution and external measures were smaller than expected, though showed evidence of discriminant validity (e.g., interviewer-rated paranoia, r = .24). When examined in the full sample, correlation magnitude was larger and follow-up analyses indicated that Reference related most specifically to paranoia (β = .32), whereas Persecution uniquely related to poor social functioning (β = -.29). Conclusion: These results demonstrate the reliability and validity of the RGPTS, though its scales related more weakly to severity in CHR individuals. The RGPTS may be useful in future work aiming to develop symptom-specific models of emerging paranoia in CHR individuals. This article is protected by copyright. All rights reserved.

Objectives There are no evidence-based interventions for reducing loneliness in family caregivers of people with dementia (ADRD caregivers), despite heightened risk. We examined feasibility, acceptability, and potential efficacy of a brief behavioral intervention, Engage Coaching for Caregivers, to reduce loneliness and increase social connection for older ADRD caregivers experiencing stress and loneliness. Methods A single-arm clinical trial of 8 individual sessions of Engage Coaching delivered remotely. Outcomes assessed 3-months post-intervention included loneliness and relationship satisfaction (co-primary) and perceived social isolation (secondary). Results Engage Coaching was feasible to deliver, with n = 25 of 30 enrolled completing at least 80% of sessions. 83% indicated the program met expectations and 100% reported the program was suitable and convenient. Improvements were observed in loneliness (standardized response mean [SRM] = 0.63), relationship satisfaction (SRM = 0.56), and perceived social isolation (SRM = 0.70). Conclusion Engage Coaching is a promising behavioral intervention to enhance social connection for older ADRD caregivers.

Molecular clock REV-ERBα is central to regulating lung injuries, and decreased REV-ERBα abundance mediates sensitivity to pro-fibrotic insults and exacerbates fibrotic progression. In this study, we determine the role of REV-ERBα in fibrogenesis induced by bleomycin and Influenza A virus (IAV). Bleomycin exposure decreases the abundance of REV-ERBα, and mice dosed with bleomycin at night display exacerbated lung fibrogenesis. Rev-erbα agonist (SR9009) treatment prevents bleomycin induced collagen overexpression in mice. Rev-erbα global heterozygous (Rev-erbα Het) mice infected with IAV showed augmented levels of collagens and lysyl oxidases compared with WT-infected mice. Furthermore, Rev-erbα agonist (GSK4112) prevents collagen and lysyl oxidase overexpression induced by TGFβ in human lung fibroblasts, whereas the Rev-erbα antagonist exacerbates it. Overall, these results indicate that loss of REV-ERBα exacerbates the fibrotic responses by promoting collagen and lysyl oxidase expression, whereas Rev-erbα agonist prevents it. This study provides the potential of Rev-erbα agonists in the treatment of pulmonary fibrosis.
