Unintended consequences of technology in competency-based education: a qualitative study of lessons learned in an OtoHNS program

BACKGROUND

Formative feedback and entrustment ratings on assessments of entrustable professional activities (EPAs) are intended to support learner self-regulation and inform entrustment decisions in competency-based medical education. Technology platforms have been developed to facilitate these goals, but little is known about their effects on these new assessment practices. This study investigates how users interacted with an e-portfolio in an OtoHNS surgery program transitioning to a Canadian approach to competency-based assessment, Competence by Design.

METHODS

We employed a sociomaterial perspective on technology and grounded theory methods of iterative data collection and analysis to study this OtoHNS program's use of an e-portfolio for assessment purposes. All residents (n = 14) and competency committee members (n = 7) participated in the study; data included feedback in resident portfolios, observation of use of the e-portfolio in a competency committee meeting, and a focus group with residents to explore how they used the e-portfolio and visualize interfaces that would better meet their needs.

RESULTS

Use of the e-portfolio to document, access, and interpret assessment data was problematic for both residents and faculty, but the residents faced more challenges. While faculty were slowed in making entrustment decisions, formative assessments were not actionable for residents. Workarounds to these barriers resulted in a "numbers game" residents played to acquire EPAs. Themes prioritized needs for searchable, contextual, visual, and mobile aspects of technology design to support use of assessment data for resident learning.

CONCLUSION

Best practices of technology design begin by understanding user needs. Insights from this study support recommendations for improved technology design centred on learner needs to provide OtoHNS residents a more formative experience of competency-based training.

Real-World Experience of Vismodegib in Advanced Basal Cell Carcinoma at a Canadian Cancer Center

BACKGROUND

Vismodegib is a novel Hedgehog pathway inhibitor that has revolutionized the treatment of patients with advanced basal cell carcinoma (BCC) who are poor candidates for surgery or radiation. Few studies have explored the use of vismodegib to facilitate further surgery or radiotherapy, and the optimal treatment duration to balance outcomes with adverse effects.

OBJECTIVES

To characterize the disease response, progression, and recurrence outcomes of BCC patients, and to report the impact of subsequent therapies.

METHODS

We performed a retrospective study of 46 adult patients with advanced basal cell carcinoma (aBCC), including both locally advanced (laBCC) and metastatic (mBCC) disease, treated with vismodegib at a single center from 2012 to 2019.

RESULTS

Thirty-six had laBCC, and 10 had mBCC. Treatment was given over a mean of 21.9 months. Twenty-three (50%) had a complete response (CR), and 19 (41.3%) achieved partial response (PR). Median time to maximal response was 5.3 months. Eleven (23.9%) had resected disease at median 17.2 months, and 11 patients (23.9%) received radiotherapy. Thirty-two (69.6%) experienced progressive disease after achievement of CR or PR. Among 17 CR patients, who stopped treatment, 14 (82.3%) experienced subsequent relapse; 6 (85%) attained a repeat response. Twenty (43.5%) discontinued treatment at least once due to adverse effects.

CONCLUSIONS

With a response rate of 91%, London Regional Cancer Center's (LRCP)'s experience with vismodegib supports its effectiveness in treatment of aBCC. Moreover, a significant number of patients treated with vismodegib became amenable to surgery or radiotherapy. Toxicity remained an important factor that limited treatment duration.

The embodiment of practice thresholds: from standardization to stabilization in surgical education

Surgeons practice their own variations on a procedure. Residents experience shifting thresholds between variations that one surgeon holds firmly as principle and another takes more lightly as preference. Such variability has implications for surgical education, but the impact is not well understood. This is a critical problem to investigate as programs seek to define procedures for competency-based medical education (CBME) and improve learning through deliberate practice. Our study analyzes the emergence of procedural variation in an early-adopter CBME program through a situational analysis of tonsillectomy, a foundation level procedure in this otolaryngology, head and neck surgical program. An earlier phase of the study identified frequent variations (n = 12) on tonsillectomy among co-located surgeons who routinely perform this procedure (n = 6). In the phase reported here we interviewed these surgeons (n = 4) and residents at different stages of training (n = 3) about their experiences of these variations to map the relations of contributing social and material actors. Our results show that even a basic procedure resists standardization. This study contributes a sociomaterial grounded theory of surgical practice as an embodied response to conditions materialized by intra-relations of human and more-than-human actors. Shifting root metaphors about practice in surgical education from standardization to stabilization can help residents achieve stable-for-now embodiments of performance as their practice thresholds continue to emerge.

Scut to Scholarship: Can Operative Notes be Educationally Useful?

OBJECTIVE

Efforts to implement competency-based medical education require new sources of workplace-based evidence of growth in learning. We used qualitative analysis of operative notes to explore procedural variation in a simple surgical procedure.

DESIGN

We used a grounded theory-based mixed methods approach to depict intersurgeon procedural variation. Our grounded theory approach to analysis included follow up interviews with surgeons and residents to probe their understandings of the reasons for variation in the dictated notes and the current and potential utility of operative notes as a reliable source of data for learning and assessment.

SETTING

Publicly funded tertiary care otolaryngology-head & neck surgery residency program in Ontario, Canada PARTICIPANTS: Using maximum variability sampling, all surgeons performing tonsillectomy in the department (n = 6) contributed operative notes from 65 tonsillectomies, 5 intraoperative observations, and 4 semi-structured interviews. An additional 3 residents from various levels of training contributed semistructured interviews.

RESULTS

Intersurgeon procedural variations persist even in simple surgical procedures such as tonsillectomy. Operative notes appear to capture procedural variations in a limited way. Surgeons and resident make informal educational use of the clerical work of writing and assessing operative notes, but optimization will be required to shift such hidden work into the formal educational domain.

CONCLUSIONS

The implementation of competency-based medical education requires surgical educators to both eliminate low-yield tasks for learning and to find new opportunities for multiple low-stakes assessment. Analysis of operative notes may become a high-yield strategy for learning and assessment if residents and surgeons are coached to use operative notes more reliably and efficiently.

Development of a novel simulation-based task trainer for management of retrobulbar hematoma

BACKGROUND

Retrobulbar hematoma (RH) is a rare but devastating complication of sinus surgery. It is treated initially with a lateral canthotomy and cantholysis at the bedside. Due to the high stakes and urgency of this complication, teaching this in the clinical setting is difficult. The objective of this study was to develop a cadaveric model for addressing this problem.

METHODS

A fresh-frozen human cadaveric model of RH was created using a Foley catheter to simulate elevated intraocular pressure. Residents who participated in an emergencies in otolaryngology-head & neck surgery "boot camp" were included in the study. A survey measuring confidence levels in performing lateral canthotomy and cantholysis was administered. After completing the skill station, a postintervention survey was administered to assess the confidence of the learner as well as fidelity and usefulness of the task trainer.

RESULTS

Thirty-three residents participated in the boot camp. Residents rated their confidence preintervention at 1.3/5, which suggests the majority were unable to perform the procedure. After using the model, residents rated their confidence at 3.5/5, which falls between basic knowledge and reasonably confident; this improvement achieved statistical significance (p < 0.0001). The fidelity of the model was rated 3.9/5; a score of 4 is defined as realistic. The residents rated the usefulness of the model as 4.7; a score of 5 is defined as very useful.

CONCLUSION

A cadaveric model of RH was successfully developed. This novel simulator was perceived to be useful, realistic, and effective by junior residents.

Perioperative Teaching and Feedback: How are we doing in Canadian OTL-HNS programs?

Background

Discrepancies between resident and faculty perceptions regarding optimal teaching and feedback during surgery are well known but these differences have not yet been described in Otolaryngology - Head and Neck Surgery (OTL-HNS). The objectives were thus to compare faculty and resident perceptions of perioperative teaching and feedback in OTL-HNS residency programs across Canada with the aim of highlighting potential areas for improvement.

Methods

An anonymous electronic questionnaire was distributed to residents and teaching faculty in OTL-HNS across Canada with additional paper copies distributed at four institutions. Surveys consisted of ratings on a 5-point Likert scale and open-ended questions. Responses among groups were analysed with the Wilcoxon-Mann Whitney test, while thematic analysis was used for the open-ended questions.

Results

A total of 143 teaching faculty and residents responded with statistically significant differences on 11 out of 25 variables. Namely, faculty reported higher rates of pre and intra-operative teaching compared to resident reports. Faculty also felt they gave adequate feedback on residents’ strengths and technical skills contrary to what the residents thought. Both groups did agree however that pre-operative discussion is not consistently done, nor is feedback consistently given or sought.

Conclusion

Faculty and residents in OTL-HNS residency programs disagree on the frequency and optimal timing of peri-operative teaching and feedback. This difference in perception emphasizes the need for a more structured approach to feedback delivery including explicitly stating when feedback is being given, and the overall need for better communication between residents and staff.

Factors associated with lingual tonsil hypertrophy in Canadian adults

Background

Hypertrophy of the lingual tonsil tissue in the adult patient is thought to contribute to the pathophysiology of obstructive sleep apnea. The underlying etiology of lingual tonsil hypertrophy (LTH) in the adult patient is unclear and likely multifactorial. Previous studies have suggested that the lingual tonsils may undergo compensatory hyperplasia post-tonsillectomy in children, although it is unknown if this occurs or persists into adulthood. The purpose of this study was to determine what factors are associated with LTH in a population of Canadian adults.

Methods

Adult patients presenting for consultation to an academic Rhinology/General Otolaryngology practice were eligible for enrollment. Demographic data including age, body mass index (BMI), Reflux Symptom Index (RSI), history of allergy, and history of tonsillectomy was collected via questionnaire. Endoscopic photographs of the base of tongue and larynx were captured. These were graded for LTH and Reflux Finding Scale (RFS) by blinded examiners. Statistical analysis was performed by comparing the mean LTH value to the variables of interest using two-tailed T-test. P < .05 was considered significant.

Results

One hundred two subjects were enrolled. Age ranged from 18 to 78. 28 patients had previous tonsillectomy. This was not associated with a significant increase in lingual tonsil tissue (r = −0.05, p = 0.61). RFS >7 or RSI >13 was considered positive for laryngopharyngeal reflux. There was no difference in LTH based on RSI positivity (p = 0.44). RFS positivity correlated with increased lingual tonsil tissue (p < 0.05). BMI >30 was associated with increased lingual tonsil hypertrophy (p < 0.05).

Conclusions

An elevated body mass index and positive Reflux Finding Score are associated with lingual tonsil hypertrophy in adults. Reflux symptom index, history of allergy and history of childhood tonsillectomy are not associated with LTH.

Malignant Proliferating Trichilemmal Tumor Treated with Radical Radiotherapy: A Case Report and Literature Review

Reported here is the first case of a malignant proliferating trichilemmal tumor treated with radical radiotherapy. Complete clinical response was achieved, and this obviated the need for aggressive surgery. These tumors have a tendency to develop in older patients, and have a propensity for affecting women more than men. The standard of treatment is surgical excision with a margin of normal tissue. Given that not all patients are good surgical candidates, the role of different treatment modalities in the management of this tumor is discussed.

Dairy farmers' perceptions toward the implementation of on-farm Johne's disease prevention and control strategies

Implementation of specific management strategies on dairy farms is currently the most effective way to reduce the prevalence of Johne's disease (JD), an infectious chronic enteritis of ruminants caused by Mycobacterium avium subspecies paratuberculosis (MAP). However, dairy farmers often fail to implement recommended strategies. The objective of this study was to assess perceptions of farmers participating in a JD prevention and control program toward recommended practices, and explore factors that influence whether or not a farmer adopts risk-reducing measures for MAP transmission. Semi-structured interviews were conducted with 25 dairy farmers enrolled in a voluntary JD control program in Alberta, Canada. Principles of classical grounded theory were used for participant selection, interviewing, and data analysis. Additionally, demographic data and MAP infection status were collected and analyzed using quantitative questionnaires and the JD control program database. Farmers' perceptions were distinguished according to 2 main categories: first, their belief in the importance of JD, and second, their belief in recommended JD prevention and control strategies. Based on these categories, farmers were classified into 4 groups: proactivists, disillusionists, deniers, and unconcerned. The first 2 groups believed in the importance of JD, and proactivists and unconcerned believed in proposed JD prevention and control measures. Groups that regarded JD as important had better knowledge about best strategies to reduce MAP transmission and had more JD risk assessments conducted on their farm. Although not quantified, it also appeared that these groups had more JD prevention and control practices in place. However, often JD was not perceived as a problem in the herd and generally farmers did not regard JD control as a "hot topic" in communications with their herd veterinarian and other farmers. Recommendations regarding how to communicate with farmers and motivate various groups of farmers according to their specific perceptions were provided to optimize adoption of JD prevention and control measures and thereby increase success of voluntary JD control programs.

Long-lived plasma cells are generated in mucosal immune responses and contribute to the bone marrow plasma cell pool in mice

During systemic immune responses, plasma blasts are generated in secondary lymphoid organs and migrate to the bone marrow, where they can become long-lived, being responsible for the maintenance of long-term antibody titers. Plasma blasts generated in mucosal immune responses of the small intestine home to the lamina propria (LP), producing mainly immunoglobulin A. The migration of these antibody-secreting cells is well characterized during acute immune responses. Less is known about their lifetime and contribution to the long-lived bone marrow compartment. Here we investigate the lifetime of plasma cells (PCs) and the relationship between the PC compartments of the gut and bone marrow after oral immunization. Our findings indicate that PCs in the LP can survive for extended time periods. PCs specific for orally administered antigens can be detected in the bone marrow for at least 9 months after immunization, indicating that the mucosal PC compartment can contribute to the long-lived PC pool in this organ, independent of the participation of splenic B cells. Our findings suggest that the compartmentalization between mucosal and systemic PC pools is less strict than previously thought. This may have implications for the development of vaccines as well as for autoantibody-mediated diseases.

Evaluation of a novel high-fidelity epistaxis task trainer

OBJECTIVES/HYPOTHESIS

To assess the efficacy of a novel high-fidelity epistaxis simulator in teaching epistaxis management to junior otolaryngology head and neck surgery residents.

STUDY DESIGN

Prospective cohort study.

METHODS

A novel high-fidelity epistaxis task trainer was developed using a cadaver head, intravenous tubing, and a food coloring-filled saline bag to emulate blood. Learners were instructed on two techniques of nasal packing (formal nasal pack and nasal tampon) for the management of epistaxis using the task trainer. Learners were videotaped attempting to pack the nose of the task trainer pre- and postintervention (verbal instruction, and practice time with task trainer). Five board-certified otolaryngologists (blinded to pre- and postintervention status) evaluated the packing technique using standardized subjective outcome measures.

RESULTS

There were 13 junior otolaryngology residents enrolled in the study. This cohort showed a statistically significant increase in global rating scores (P < 0.05) in all items measured for both packing methods.

CONCLUSION

This novel cadaveric epistaxis simulator has been successful in teaching and the practical application of various skills in epistaxis management. This task trainer appears to confer an educational benefit in technical skills acquisition in novice learners. Further studies are needed to determine long-term skill retention. Simulation is a promising educational adjunct that effectively enhances epistaxis management skills acquisition while maximizing patient safety.

Emergencies in otolaryngology-head and neck surgery bootcamp: a novel Canadian experience

OBJECTIVES/HYPOTHESIS

A 1-day intensive course (bootcamp) was developed, to teach junior otolaryngology-head and neck surgery (OTO-HNS) residents emergency procedural skills, clinical reasoning, and communication skills. This learning paradigm utilized a number of novel task trainers, panel discussions, and emergency simulations. The study objective was to assess the educational value of this bootcamp.

STUDY DESIGN

Prospective cohort survey.

METHODS

Residents were recruited from regional teaching centers within a 2000-km radius of the simulation center. Preceptors fluent in English and in French were in attendance. Pre-bootcamp outcome measures included the Kolb Learning Style Inventory and a self-administered survey measuring confidence levels in performing specific OTO-HNS tasks. Post-bootcamp outcome measures included a survey evaluating the bootcamp experience and a structured follow-up telephone interview.

RESULTS

Twenty-eight residents participated in the bootcamp from across the United States and Canada. When asked if they felt that "overall, the educational day was an effective learning process," the average score was 4.75/5.0. The vast majority of participants (92.9%) felt they would recommend the bootcamp to a future junior resident. Kolb learning styles that prefer active experimentation (acting, initiating, and deciding) were more common than those that utilize reflective observation (imagining, analyzing, reflecting), which favors a hands-on model of learning.

CONCLUSION

This first Canadian OTO-HNS bootcamp demonstrated the feasibility and effectiveness of conducting a centralized bootcamp for regional training centers spanning multiple states/provinces and languages. Future bootcamps will be held annually and will ideally continue the natural evolution of surgical, hands-on training.

Hydration of endo-Tricyclo[5,2,1,02,6]deca-3,8-diene (endo-Dicyclopentadiene) / Über die Hydratisierung von endo-Tricyclo[5.2.1.02,6]deca-3.8-dien (endo-Dicyclopentadien)

The hydration of endo-dicyclopentadiene (1) yields a 1:2 mixture of exo-8-hydroxy-exotricyclo[5,2,1,02,6]dec-3-ene (2) and exo-9-hydroxy-exo-tricyclo[5,2,1,02,6]dec-3-ene (3). The structures of these compounds were determined by 1H and 13C spectroscopy with simultaneous application of paramagnetic shift reagent Eu(fod)3. The stereospecific exoattack of the proton in the first reaction step is demonstrated by the reaction in deuteriumoxid.

Struktur und Reaktivität von 4-Hydroxy-5-oximino-7-methyl-5H-pyrano-[2.3-b]-pyridin-8-oxid / Structure and Reactivity of 4-Hydroxy-5-oximino-7-methyl-5H-pyrano-[2,3-b]-pyridine-8-oxide

For the reaction product of 1 with dimethylformamidedimethylacetal in the presence of hydroxylamine there might exist five possible tautomeric forms 2 a-e. The structure of the title compound was determined to be 2 d by applying carbon-13 NMR spectroscopy to 2 a-e and some derivatives 8-5 in DMSO-d6 resp. DMSO-d6/NaOD.

Against all odds: a qualitative study of rehabilitation of persons with spinal cord injury in Afghanistan

STUDY DESIGN

Cross-sectional, survey.

OBJECTIVES

To describe the challenges in rehabilitating patients with spinal cord injury in the orthopaedic centres of the International Committee of the Red Cross in Afghanistan.

SETTING

Afghanistan (Kabul, Herat, Mazar-i-Sharif, Jalalabad, Gulbahar), April 2012.

METHODS

Semi-structured interviews were conducted with managers and professional staff of ICRC and other concerned organizations/institutions (Ministries, hospitals, non-governmental organizations), and with people with SCI and their families. Quantitative data were extracted from routine statistics.

RESULTS

A reported annual incidence of roughly 21 SCI cases per million in Afghanistan could be established for the year 2011. Acts of violence were the most frequent cause, followed by spinal tuberculosis. Despite very elementary prehospital and hospital care, SCI individuals are rehabilitated within the limits set by available technology and socio-economic factors. Support to community reintegration is effective for the ones living within a radius determined by distance and security.

CONCLUSION

Rehabilitation of SCI patients would be ineffective without covering at least part of the services usually provided during the phases of acute hospital care and community reintegration. The question of whether services currently provided by foreign-based or funded organizations can be extended into a potential postconflict period, and by whom, remains open.

Phase II study of first-line sagopilone plus prednisone in patients with castration-resistant prostate cancer: a phase II study of the Department of Defense Prostate Cancer Clinical Trials Consortium

BACKGROUND

Preclinical studies in prostate cancer (PC) models demonstrated the anti-tumour activity of the first fully synthetic epothilone, sagopilone. This is the first study to investigate the activity and safety of sagopilone in patients with metastatic castration-resistant PC (CRPC).

METHODS

Chemotherapy-naïve patients with metastatic CRPC received sagopilone (one cycle: 16 mg m(-2) intravenously over 3 h q3w) plus prednisone (5 mg twice daily). The primary efficacy evaluation was prostate-specific antigen (PSA) response rate (≥50% PSA reduction confirmed ≥28 days apart). According to the Simon two-stage design, ≥3 PSA responders were necessary within the first 13 evaluable patients for recruitment to continue until 46 evaluable patients were available.

RESULTS

In all, 53 patients received ≥2 study medication cycles, with high compliance. Mean individual dose was 15.1±1.4 mg m(-2) during initial six cycles, mean dose intensity 94±9%. The confirmed PSA response rate was 37%. Median overall progression-free survival was 6.4 months. The most commonly reported adverse events (>10% of patients) were peripheral neuropathy (94.3%), fatigue (54.7%) and pain in the extremities (47.2%). Sagopilone was associated with very little haematological toxicity.

CONCLUSION

This study shows that first-line sagopilone has noteworthy anti-tumour activity and a clinically significant level of neuropathy for patients with metastatic chemotherapy-naïve CRPC.

Type I thyroplasty: risk stratification approach to inpatient versus outpatient postoperative management

BACKGROUND

type I thyroplasty is an effective and safe procedure for unilateral vocal fold paralysis and is shifting toward outpatient postoperative care. However, serious airway complications have been reported.

OBJECTIVES

the aims of this study were to investigate whether risk stratification into inpatient/outpatient postoperative care reduces outpatient airway complications and to compare the cost-effectiveness and surgical outcomes of risk stratification to a historical inpatient control group (non-risk stratified).

SETTING

tertiary, university-based medical centre.

DESIGN AND RESULTS

Three retrospective groups were examined: historical inpatient control (n = 15), risk-stratified (RS)- inpatient (n = 16), and RS outpatient (n = 17). Laryngeal edema was encountered in two historical controls (13.3%), two RS inpatients (12.5%), and one RS outpatient (5.9%). One case of implant extrusion occurred in the RS outpatient group. There was no difference in maximum phonation time or voice-related quality of life between RS versus historical controls (p > .5). The cost savings of risk stratification versus entirely inpatient care was $CAD 633.12/patient. The average duration in hospital for RS inpatient versus RS outpatient was 29.8 and 8.3 hours, respectively.

CONCLUSIONS

postoperative RS may reduce potentially serious outpatient airway complications and cost while improving patient satisfaction.

Inactivation of animal and human prions by hydrogen peroxide gas plasma sterilization

Prions cause various transmissible spongiform encephalopathies. They are highly resistant to the chemical and physical decontamination and sterilization procedures routinely used in healthcare facilities. The decontamination procedures recommended for the inactivation of prions are often incompatible with the materials used in medical devices. In this study, we evaluated the use of low-temperature hydrogen peroxide gas plasma sterilization systems and other instrument-processing procedures for inactivating human and animal prions. We provide new data concerning the efficacy of hydrogen peroxide against prions from in vitro or in vivo tests, focusing on the following: the efficiency of hydrogen peroxide sterilization and possible interactions with enzymatic or alkaline detergents, differences in the efficiency of this treatment against different prion strains, and the influence of contaminating lipids. We found that gaseous hydrogen peroxide decreased the infectivity of prions and/or the level of the protease-resistant form of the prion protein on different surface materials. However, the efficiency of this treatment depended strongly on the concentration of hydrogen peroxide and the delivery system used in medical devices, because these effects were more pronounced for the new generation of Sterrad technology. The Sterrad NX sterilizer is 100% efficient (0% transmission and no protease-resistant form of the prion protein signal detected on the surface of the material for the mouse-adapted bovine spongiform encephalopathy 6PB1 strain and a variant Creutzfeldt-Jakob disease strain). Thus, gaseous or vaporized hydrogen peroxide efficiently inactivates prions on the surfaces of medical devices.

FOXP3 expression in blood, synovial fluid and synovial tissue during inflammatory arthritis and intra-articular corticosteroid treatment

OBJECTIVE

To analyse the distribution of FOXP3+CD25+CD4+ regulatory T cells (Treg) in peripheral blood, synovial fluid and tissue of patients with rheumatic disease during relapse and after local treatment.

METHODS

FOXP3 expression was assessed by flow cytometry, immunohistochemistry, immunofluorescence and real-time polymerase chain reaction (RT-PCR). The functional suppressive capacity of Treg was analysed after co-culture with effector CD4+CD25- T cells through assessment of proliferation and cytokine secretion.

RESULTS

It was shown that FOXP3 protein and mRNA expression in synovial fluid T cells was not confined solely to CD25(bright) T cells as seen in blood, but included CD25(intermediate) and even CD25(neg) T cells. Indeed, synovial fluid CD25(high) T cells showed similar suppressive capacity as CD25(bright) T cells, indicating the presence of functional Treg in T cells with lower intensity of CD25. In synovial tissue, FOXP3+ cells were present in low numbers within T-cell infiltrates and decreased further after intra-articular glucocorticosteroid administration, in parallel with the general reduction in inflammation.

CONCLUSIONS

Identification of synovial fluid FOXP3+ Treg with varying intensities of CD25 opens up possibilities for thorough characterisation of this important T-cell subset in the inflammatory compartment. However, only scarce synovial membrane expression of FOXP3 was found even in the absence of overt inflammation, suggesting that the synovial membrane is a site that would benefit therapeutically from Treg expansion.
